Description

The load character regulating system of oval section volute spring
Technical field
The present invention relates in a kind of online spring building mortion, reel through making to dock with the forming tool that is configured in its place ahead from the wire rod of forwards seeing off as the wire rod unloading part of wire rod guide member, thus the load character regulating system of the oval section volute spring that is shaped.
Background technology
The device that the line spring is shaped as passing through wound skein product, the device of known patent document 1 (TOHKEMY 2004-237352 number).According to this device; Wire rod passes out to the shaping platform through the wire rod force feed mechanism with mip rolls from quill (wire rod unloading part); With from docking with coiled material forming tool that the direction of the axis quadrature of wire rod is advanced towards line spring shaping platform and make its coiling, thereby be configured as coiled material.
In addition, the diameter of the coiled material of shaping changes according to the distance of coiled material forming tool and quill.That is, for the diameter of the coiled material that is shaped, the distance of forming tool and quill is near more, and roll diameter is more little, and the distance of forming tool and quill is far away more, and roll diameter is big more.Thereby; Through this line spring building mortion; Move to uniform velocity making on the axis direction of quill at wire rod by quill travel mechanism (with quill from the forming tool uniform velocity draw back) in, make from the quill uniform velocity under the wire rod seen off and the situation that the coiled material forming tool docks; Roll diameter gradually changes (increase) along axis direction, the spring of the conical shaped shape that therefore is shaped.
But, in the wire rod of the raw material that becomes oval section volute spring, because the difference of making batch etc., the difference of small characteristics such as deviation can wired footpath be arranged.Thereby, promptly use the different knifeedge wire rod of characteristic to form the oval section volute spring of same shape, ready-made oval section volute spring tends on the load character that obtains, produce deviation, does not possess the load character that preset range is gone up in design.Thereby, when forming oval section volute spring, need carry out operation that the load character that obtains is regulated according to batch grade of wire rod.
Therefore, the adjusting of the load character of oval section volute spring is to change knifeedge through the ready-made shape with oval section volute spring to carry out.For example; In the oval section volute spring; When making the oval section volute spring periphery with respect to the gradient of coiled material central axis direction, promptly when the increase degree of the roll diameter of coiled material central axis direction changes, because the delicate variation of profile, and the load character that obtains is changed knifeedge.The oval section volute spring periphery is with respect to the gradient of coiled material central axis direction, through as Fig. 7 (a) set line spring building mortion, and shown in Fig. 7 (b), roughly Fuji type, pyramid type and roughly changing between the bowl type roughly.
Particularly, in the setting of online spring building mortion, the translational speed of quill is fixed as uniform velocity, make from the quill uniform velocity the feed speed of the wire rod seen off on the way switch.
The setting of the wire rod feed speed in the line spring building mortion when Fig. 7 (a) expression is shaped oval section volute spring, Fig. 7 (b) expression is according to the ready-made shape of setting.The picture left above of Fig. 7 (a) and each transverse axis of top right plot are represented the feeding time t from the wire rod of quill respectively.Symbol t1 representes the time till the wire rod feed speed is switched, and t2 representes total feeding time of wire rod.In addition, the longitudinal axis of the picture left above of Fig. 7 (a) is represented the amount of feeding X of wire rod, and the longitudinal axis of top right plot is represented the feed speed V from the wire rod of quill.The transverse axis of left figure below of Fig. 7 (a) is represented traveling time (t1, t2 identical with the feeding time of the wire rod) t of quill, representes the displacement P of quill with the longitudinal axis of figure.
Set line spring building mortion with the such as stated mode that between the P1 to P3 shown in Fig. 7 (b), moves to constant speed (drawing back) of quill from the coiled material forming tool.On the other hand, set line spring building mortion with such mode of wire rod being seen off from quill with two stage uniform velocity shown in Fig. 7 (a) top right plot.
The coiled material circumferential length of the oval section volute spring that is shaped by line spring building mortion, with compare the coiling terminal near the coiling top near longer certainly.Thereby; For example, shown in the top right plot (double dot dash line part) of Fig. 7 (a), under situation about wire rod being seen off with certain speed V0 from the coiled material that moves to P3 with uniform velocity ground from P1; Shown in the left figure of Fig. 7 (b); The coiled material circumferential length increases to the coiling terminal from coiling top gradually, with respect to this, does not increase but certain from the amount of feeding (feed speed) of the wire rod of quill; The moving ratio of the quill when therefore coiled material being reeled a week becomes big gradually from coiling top to the coiling terminal.Thereby the oval section volute spring periphery is with respect to the inclination of coiled material central axis L 0 direction, shown in the left figure of Fig. 7 (b), and compares near the coiling top, and inclination is more anxious near the coiling terminal.The result; The left figure of Fig. 7 (b) as shown in; When establish P1 that quill moves between the P2 for preceding half (following only be called before half), establish P2 between P3 during for later half (following only be called later half); The oval section volute spring periphery is with respect to the inclination of coiled material central axis L 0, and half slow, later half urgency before forming is so ready-made oval section volute spring is formed the roughly Fuji type that periphery caves in to the inside (following this shape is expressed as roughly Fuji type).
On the other hand, the oval section volute spring periphery is with respect to the inclination of coiled material central axis L 0, if with the feed speed speedup of wire rod then tilt to slow down, if the feed speed of wire rod is slowed down then tilt to become anxious.Therefore; Shown in Fig. 7 (a) top right plot (solid line part); Will (feed speed of the wire rod of 0 ~ t1) quill located is slowed down from V0, and (the wire rod feed speed of t1 ~ t2) be under the situation of V0 speedup for the uniform velocity V2 of regulation, and the inclination of oval section volute spring periphery is shown in the figure of Fig. 7 (b) central authorities for the uniform velocity V1 of regulation, with later half from preceding half; Preceding half is more anxious than (b) left figure, later half more slow.As a result, the ready-made shape of oval section volute spring is transformed to the roughly certain roughly pyramid type of the inclination of periphery (following this shape is expressed as roughly pyramid type) slightly from Fuji type roughly, can finely tune resulting load character.
And; Shown in Fig. 7 (a) top right plot (chain-dotted line part); In that (0 ~ t1) wire rod feed speed is further slowed down from V1, and (the wire rod feed speed of t1 ~ t2) is under the situation of V4 from the V2 speedup, and the inclination of oval section volute spring periphery is shown in the right figure of Fig. 7 (b) for V3, with later half with preceding half; Preceding half is more anxious, later half more slow than the figure of (b) central authorities.As a result, the ready-made shape of oval section volute spring is changed to the outstanding laterally roughly bowl type of periphery (following this shape is expressed as a bowl type) slightly from pyramid type roughly, can further finely tune resulting load character.
As stated; The fine setting of the load character of oval section volute spring is in the past carried out through following action: according to preceding half the uniform velocity variable till the time t1 that sets in the line spring building mortion, move to P2 to quill from P1 (be made as a) here with quill from P2 move to P3 from time t1 to t2 till the combination of later half uniform velocity variable (being made as b here) manufacture experimently oval section volute spring; If the load character that can not get stipulating; Then the operating personnel sets change to the combination of uniform velocity variable (a, b); Manufacturing experimently the different knifeedge oval section volute spring of shape from the Fuji type to bowl roughly once more the type; Carry out the trial-production of oval section volute spring repeatedly, up to the oval section volute spring of the load character that obtains having regulation.

Like Fig. 4, shown in 5; Wire rod 1 from wire rod unloading part 158 is seen off and docking groove through tipped tool 160 is bent along the face with helical spring shaping direction quadrature contacts with the pushing face 167 of pitch instrument 154 when the inboard with bending directs into axle 153.The wire rod 1 that contacts with pushing portion 167, the as shown in Figure 6 pushing to helical spring shaping direction (CF direction) through quilt is wound as helical form, therefore becomes to be helical spring.After helical spring is shaped, with constitute can to the front end of the parting tool 155 of shaping platform 200 advance and retreat push and shove wire rod 1 answer off-position and with its cut-out.
The helical spring pitch that is shaped increases to the distance that the CF direction moves with the pitch instrument 154 of the state that wire rod 1 is docked with pushing portion 167 pro rata, and it is more little to return the CR direction.
The shaping of oval section volute spring is carried out through along with the coiling that carries out wire rod 1 roll diameter being increased and decreased gradually.In the coiling machine 150 of the application first embodiment; For example; As shown in Figure 6; Through control not shown cam make with motor the sliding stand 161 that carried tipped tool 160 with the uniform velocity of regulation along axis X 1 to the right (TR direction) thus move and tipped tool 160 drawn back gradually from wire rod unloading part 158, and the wire rod of seeing off with the uniform acceleration of regulation from wire rod unloading part 158 1 is docked with the docking groove 159 of tipped tool 160, thereby can be shaped oval section volute spring.Perhaps also can be opposite with it; Uniform acceleration through with regulation makes sliding stand 161 (tipped tool 160) move to the TR direction; And the wire rod of seeing off with the uniform velocity of regulation from wire rod unloading part 158 1 is docked with docking groove 159, thereby can form oval section volute spring.
In addition; The ready-made shape of oval section volute spring; Through make the feeding uniform acceleration of the situation downward modulation nodel line material that sliding stand 161 (tipped tool 160) moves to uniform velocity by being controlled at shown in following; And regulate the mobile uniform acceleration of the sliding stand 161 under the situation that wire rod is seen off with uniform velocity, thereby can be at Fuji type roughly, pyramid type and roughly regulating easily and freely between the bowl type roughly.
Control method according to the line spring building mortion of Fig. 8 when oval section volute spring is shaped specifies.Shown in Fig. 8 (a) is the control method of each embodiment of the application.The picture left above of Figure 12 (a) and each transverse axis of top right plot are represented the elapsed time t from the wire rod feeding of wire rod unloading part 158 respectively; The longitudinal axis of said the picture left above is represented the amount of feeding X from the wire rod of wire rod unloading part 158 respectively, and the longitudinal axis of said top right plot is represented the feed speed V from the wire rod of wire rod unloading part 158.The transverse axis of left figure below of Fig. 8 (a) has represented to carry the traveling time t of the sliding stand 161 of tipped tool 160, and the longitudinal axis of said left figure below is represented the amount of movement P of sliding stand 161.
Tipped tool 160 (sliding stand 161) is used motor through the not shown cam of Numerical Control, and the wire rod of seeing off from wire rod unloading part 158 1 is docked with docking groove 159, and moves t2 time from the P1 of left figure below of Fig. 8 (a) to P3 with uniform velocity along axis X 1.Numerical Control through not shown charging motor; Shown in the top right plot of Fig. 8 (a); Be always under the situation of uniform velocity V0 in the feed speed of supposition from the wire rod of wire rod unloading part 158; Same with in the past, shown in the left figure of Fig. 8 (b), form the oval section volute spring of the inboard roughly Fuji type that caves in of mediad of oval section volute spring outer peripheral face.
In the present embodiment, the feed speed that kind shown in the top right plot of Fig. 8 (a) that line spring building mortion is set at wire rod becomes V=a (t-t1)+V0, and wire rod is seen off with the uniform acceleration of regulation from the wire rod unloading part.A is the variable (for example 0 ~ 100 operating personnel manually set the integer 0 or more of change etc.) relevant with acceleration.T is the elapsed time of wire rod feeding, and t1 is the fixed value (t2 is the total feed time of wire rod) that becomes the official hour of t1<t2, and V0 is and the relevant fixed value of stipulating of uniform velocity.The operating personnel is setting on the basis of fixed value (t2, t1, V0) in the online spring building mortion in advance; Through setting changing be 0,1 with variable a, trial-production oval section volute spring in the feeding acceleration that 2...100 changes wire rod, manufacture experimently repeatedly up to the load character that obtains stipulating.
When increasing variable a, be the center with the position of time t1, speed V0, make the speed slope, to be that acceleration becomes big.It is such that the wire rod amount of feeding of this moment becomes Fig. 8 (a) the picture left above.Promptly; When a=0, the wire rod amount of feeding becomes X=V0 * t, begins to finish to feeding from the feeding of wire rod; The oval section volute spring periphery becomes anxious gradually with respect to the inclination of central axis L 0, therefore can form the oval section volute spring of roughly Fuji type such shown in the left figure of Fig. 8 (b).
On the other hand, when the operation personnel increase the setting value a relevant with acceleration for a=1,2,3 the time, wire rod amount of feeding X becomes X=a/2 * t 2+ (V0-a * t1) * t, see off with acceleration curve shape such shown in the solid line of Fig. 8 (a) the picture left above.That is, wire rod is compared during with the setting of having carried out a=0, partly slowly sees off preceding, see off fast later half, so the oval section volute spring periphery is later half roughly certain with respect to the preceding half-sum that is tilted in the wire rod feeding of central axis L 0.As a result, the ready-made shape of oval section volute spring becomes when setting a such " roughly pyramid type " shown in the figure of central authorities of Fig. 8 (b).
And, the operating personnel a is set than said " setting a " big situation under, shown in the chain-dotted line of Fig. 8 (a) the picture left above; Preceding half wire rod feeding is slower; Later half wire rod feeding is faster, so preceding half change that is tilted in the wire rod feeding of oval section volute spring is anxious, slows down later half.As a result, the ready-made shape of oval section volute spring becomes " roughly bowl type " such shown in the right figure of Fig. 8 (b) when certain value a.
If the such as stated ground of operating personnel is to having the wire rod of specific characteristic; Variable that only will be relevant with the feeding acceleration of wire rod for example from a=0 change to 1,2 ... 100; The ready-made shape that then can make oval section volute spring is changed to roughly bowl type (perhaps make the increase ratio of pitch different) knifeedge from Fuji type roughly, regulates the load character that obtains.Manufacture experimently variform oval section volute spring repeatedly; And make resulting load character be included in the optimum value that setting value a under the situation in the prescribed limit becomes the wire rod of this batch; If, then can volume production have oval section volute spring as the load character of purpose therefore with setting value a volume production oval section volute spring.The operating personnel just can regulate load character as long as a kind of variable relevant with acceleration set change, and does not need the variable of change more than two as in the past " combination of speed ".Thereby, easily confirm best setting value a through wire rod to characteristic with regulation, can easily regulate the load character of the oval section volute spring that obtains.
In addition; In the present embodiment; With the translational speed of tipped tool 160 (sliding stand 161) be fixed as uniform velocity, and the uniform acceleration of regulating the wire rod of seeing off from wire rod unloading part 158 1 make the ready-made change in shape of oval section volute spring; But, also can be in contrast, in the setting of coiling machine 150; For example; Even with seeing off of wire rod 1 be fixed as uniform velocity and make sliding stand 161 move and regulate its uniform acceleration that moves with the such uniform acceleration of the condition (amount of movement of sliding stand 161 satisfies the definition of X, and translational speed satisfies the definition of V) that satisfies Fig. 8 the picture left above, top right plot (regulates the setting value relevant with acceleration a), the ready-made shape that also can make oval section volute spring likewise (from Fuji type roughly to bowl type roughly) variation is carried out the adjusting of load character.In addition; Under the situation that has disposed a plurality of tipped tools 160 that can advance and retreat to the central shaft X2 of oval section volute spring (not shown); The sliding stand 161 that has carried each tipped tool 160 is moved with the such uniform acceleration of condition that satisfies Fig. 8 the picture left above, top right plot, and regulate the uniform acceleration that it moves.
On the other hand, the load character of oval section volute spring also can be regulated through the pitch metamorphosis that makes oval section volute spring.The load of oval section volute spring is that the pitch of path side becomes greatly, the pitch of big footpath side diminishes if be adjusted to, and then dies down, and diminishes if be adjusted to the pitch change of path side pitch big, footpath side greatly, and is then opposite, can grow.
According to this viewpoint; The load of oval section volute spring is regulated; The translational acceleration that also can replace above-mentioned oval section volute spring sliding stand 161 (tipped tool 160) is regulated and the adjusting of wire rod feeding acceleration, carries out and regulate through the translational acceleration of pitch instrument 154 from uniform acceleration to oval section volute spring shaping direction (CF direction) that move with.
Make pitch instrument 154 under the situation that the CF direction that oval section volute spring is shaped moves with uniform acceleration in the control through not shown actuating mechanism, the pitch of oval section volute spring is quickened to increase to the CF of Fig. 6 direction.Under the situation of the mobile uniform acceleration of having regulated pitch instrument 154, the increase metamorphosis of pitch, the ready-made shape of oval section volute spring changes knifeedge, therefore can carry out the adjusting of the resulting load character of oval section volute spring.
Therefore; In the setting of coiling machine 150; For example, if wire rod 1 is fixing from the speed (or speed) that moves of the feed speed (or acceleration) of wire rod unloading part 158 and sliding stand 161, (amount of movement of pitch instrument 154 satisfies the definition of X with the condition that satisfies Fig. 8 the picture left above, top right plot and make pitch instrument 154; Translational speed satisfies the definition of V) such uniform acceleration moves; And regulate its uniform acceleration that moves and (regulate the setting value relevant a), ready-made shape is changed according to the variation of the pitch increment of oval section volute spring, carry out the adjusting of load character with acceleration.
At this moment; If the operating personnel is in the setting of coiling machine 150; Only will (regulate through the translational acceleration of pitch instrument 154 under the situation of load character with the translational acceleration of sliding stand 161; Be the translational acceleration of pitch instrument) a relevant variable for example from a=0 change to 1,2 ... 100; The ready-made shape that then can make oval section volute spring is changed to roughly bowl type (perhaps make the increase ratio of pitch different) knifeedge from Fuji type roughly, regulates the load character that obtains.If the setting value a that manufactures experimently variform oval section volute spring repeatedly and be included under the situation in the prescribed limit with resulting load character comes the volume production oval section volute spring, then can have oval section volute spring through the wire rod volume production of this batch as the load character of purpose.The operating personnel only sets the load character that the oval section volute spring that obtains just can be easily regulated in change to a kind of variable relevant with acceleration.
Then, according to Fig. 9 ~ Figure 12 second embodiment of the line spring building mortion that can oval section volute spring be shaped is described.
With wire rod unloading part 158 is fixing and make first embodiment of tipped tool 160 side shiftings opposite; In the line spring building mortion 300 of second embodiment; Coiled material forming tool 120 through will being equivalent to tipped tool 160 is fixing to move axis X 1 direction of the quill 10 side direction wire rods that are equivalent to wire rod unloading part 158, carries out the shaping of oval section volute spring and the adjusting of load character.
In these figure; Line spring building mortion 300 shown in the present embodiment constitutes; Possess: wire rod delivering mechanism 20, have wire rod 1 with clamping via the wire rod guide member, be a pair of mip rolls 22,22 that quill 10 shaping platform 100 (referring to Fig. 9) is forwards seen off; And can be to the coiled material forming tool 120 of shaping platform 100 advance and retreat actions; Through making coiled material forming tool 120 before shaping platform 100 and then with wire rod 1 that leading section from quill 10 passes out to shaping platform 100, dock and make its coiling, thus helical spring is shaped.
Mark 3 is arranged on the fixed mount on the pallet 2, and fixed mount 3 is provided with along the axis X 1 of wire rod 1 and makes quill 10 advance and retreat actions and make the dynamic linear slide block 50 (the winding diameter governor motion after the present techniques scheme 1) that changes in interval between coiled material forming tool 120 and the quill 10.That is, on fixed mount 3, can be equipped with the sliding stand 52 that is equipped with quill 10 and wire rod delivering mechanism 20 via travelling carriage 4 integratedly slidably along the axis X 1 of wire rod 1.With sliding stand 52 incorporate quills 10,, can move to KF direction shown in Figure 10 or KR direction advance and retreat along the axis X 1 of wire rod 1 via the ball-screw 54 that drives through the servo motor M50 rotation that is arranged on the fixed mount 3.The mip rolls 22,22 of Fig. 9 is through being activated the driving force with motor M22 via not shown gear mechanism, and the roller 22 that makes the top widdershins, the roller 22 that makes the below deasil rotates and the wire rod 1 of clamping is passed out to shaping platform 100 from quill 10.
In addition, along with the direction of axis X 1 quadrature of wire rod 1 above dispose linear slide block 110.On this linear slide block 110 while carrying the instrument sliding stand 112 of coiled material forming tool 120, instrument sliding stand 112 is through servo motor M110 and with respect to the line spring shaping platform 100 advance and retreat actions of quill 10 front ends.Between the output shaft and instrument sliding stand 112 of servo motor M110, the rotation that is clamping servo motor M110 converts straight-line crank mechanism 114 into, comes the advance and retreat action of control tool sliding stand 112.
Coiled material forming tool 120 becomes the structure that on the instrument sliding stand 112 of action of can advancing and retreat, has carried instrument rotary unit 131 and made the servo motor M132 of rotary unit 131 rotations; This instrument rotary unit 131, at rotary body with rotating shaft parallel 133 with the advance and retreat direction of instrument sliding stand 112, be clip said rotating shaft 133 in the tool 132 and be provided with opposed to each other left side volume with and a pair of coiled material forming tool main body 134A, the 134B of right volume usefulness.Mark 132a is the gear on the output shaft that is contained in servo motor M132, and mark 133a is that axle is contained in the gear on the rotating shaft 133, meshes and the motor driving force is delivered to rotary unit 131 through two gear 132a, 133a.
In this coiled material forming tool 120C; Can therefore can in shaping platform 100, switch the right side volume that dock with wire rod 1 simply and use and left tool body 134A, the 134B that rolls up usefulness through driving servo motor M132 and the right volume of configuration on the contrary use tool body 134B with tool body 134A with left side volume.
In addition; Like Figure 11 (a) (b) shown in (c); On the bight, left and right side of the tool 132 of flat rectangular block shape, dispose right volume with each wire rod interface (136,137) of the groove (136a, 137a) that is formed with wire rod engaging usefulness towards opposite mode and roll up with a left side with tool body 134A and use tool body 134B.Shown in Figure 11 (b); The slot 136a of right volume usefulness is the pair of parallel groove that reduces to the right with the front end of tool body 134A along with the volume towards the right side; Shown in Figure 11 (c), the slot 137a of left side volume usefulness is the pair of parallel groove that reduces left with the front end of tool body 134B along with the volume towards a left side.
Under the situation that helical spring is shaped; Control through instrument sliding stand 112; Coiled material forming tool 120 is advanced to the CF of Figure 10 direction towards shaping platform 100; Tool body 134A (or 134B) and quill 10 are disposed opposed to each other, and dock with wire rod 1 that leading section from quill 10 passes out to shaping platform 100.Under rolling up with tool body 134A and quill 10 opposed situation on the right side, wire rod 1 is along the wire rod docking groove 136a that reduces to the right of Figure 11 (b) such right volume coiling shown in figure 12.In addition, make through servo motor M132 tool 132 Rotate 180s ° make left side volume with tool body 134B and quill 10 opposed situation under, wire rod 1 left side is rolled up coiling through the wire rod docking groove 137a that reduces left.
The helical spring volume footpath that is shaped increases with the distance of tool body 134A (or 134B) and quill 10 pro rata.Thereby; Under the situation that the oval section volute spring with that kind shown in figure 12 is shaped; For example, as long as the Numerical Control through servo motor M50, make carried the sliding stand 52 of seeing wire rod off in the process quill 10 with uniform acceleration along axis X 1 to the KR of Figure 10 direction uniform velocity move; Quill 10, is made wire rod 1 dock with wire rod docking groove 136a (or 137a) and gets final product when drawing back from tool body 134A (or 134B).Perhaps; As long as control through servo motor M50; Make and carried when wire rod seen off the sliding stand 52 of the quill 10 in the process KR direction of Figure 10 moves with uniform acceleration left along axis X 1 with uniform velocity, wire rod 1 is docked with wire rod docking groove 136a (or 137a) get final product.
In addition; In the setting of online spring building mortion 300, for example, through the mobile uniform velocity that is fixed as with sliding stand 52 (quill 10); (amount of feeding of wire rod 1 satisfies the definition of X with the condition that satisfies Fig. 8 the picture left above, top right plot with wire rod 1 from quill 10; Feed speed satisfies the definition of V) such uniform acceleration is seen off, and the uniform acceleration of adjusting wire rod feeding (is regulated the setting value relevant with acceleration a), perhaps in contrast; To be fixed as uniform velocity from the feed speed of the wire rod 1 of quill 10; Sliding stand 52 (quill 10) is moved with the such uniform acceleration of condition (amount of movement of sliding stand 52 satisfies the definition of X, and translational speed satisfies the definition of V) that satisfies Fig. 8 the picture left above, top right plot, and regulate its uniform acceleration and (regulate the setting value relevant a) with acceleration; Can make the change in shape of oval section volute spring thus, and regulate the load character that obtains.
At this moment; In the setting of the online spring building mortion 300 of operating personnel; Only through will with the feeding acceleration of wire rod 1 (perhaps; Regulating under the situation of load character through the mobile control of sliding stand 52; Be the translational acceleration of sliding stand 52) a relevant variable for example from a=0 change to 1,2 ... 100, the ready-made shape that just can make oval section volute spring is changed to roughly bowl type (perhaps make the increase ratio of pitch different) knifeedge from Fuji type roughly, and easily regulates the load character that obtains.
