above mentioned bend pipe mould 5 has a bend pipe mould sleeve block 52 back to central authorities' formation of a side of the 4th drive 42, central authorities at the length direction of this bend pipe mould sleeve block 52 form the axle sleeve mating holes 521 that a perforation is arranged, and realize coordinating of bend pipe mould 5 and the 4th drive 42 by this axle sleeve mating holes 521 is placed on aforesaid axle sleeve 421.And the edge at bend pipe mould 5 towards the circumferencial direction of a side of the 4th drive 42 forms one group of boss nut 53 that respectively has internal thread hole is arranged with the interval state, use the one group of boss nut hold-down screw 531 equated with the quantity of boss nut 53 in the position corresponding to being preset in the screw hole 422 on the 4th drive 42, that boss nut 53 and the 4th drive 42 is fixing.
bend pipe mould 5 side outward has a flat back die 51 back to a side formation of aforesaid the 4th drive 42, edge at flat back die 51 forms the bend pipe chamber 511 that one group of each interval is arranged, this organizes bend pipe chamber 511 stepped arrangement each other, forms each other the ladder relation.Hence one can see that, and the shape of flat back die 51 is the shape that has a regional circular cone stage body of disappearance, particularly, the diameter of flat back die 51 from bend pipe mould 5 towards deviating from (away from) the direction narrow contracting gradually of bend pipe mould 5.As shown in Figure 1, the shape of cross section in each bend pipe chamber 511 takes the shape of the letter U.
although illustrated in the present embodiment four bend pipe chambeies 511, and the diameter in twice (two) the bend pipe chamber 511 of close bend pipe mould 5 is larger than the diameter in twice (two) the bend pipe chamber 511 away from bend pipe mould 5, so that the pipe 9 of reply different-diameter, but the quantity in bend pipe chamber 511 is not subject to illustrating the restriction of quantity.Also can tackle the bending machining of the pipe 9 of different tube diameters by changing bend pipe mould 5.
when the 4th drive 42 rotation, drive 5 rotations of bend pipe mould.In order to carry out spacing to pipe 9, the utility model is fixed with a body stop 7 at the sidepiece of an end of aforesaid flat back die 51, the base portion of the length direction of body stop 7 offers one group of fixing hole 71, with one group of stop hold-down screw 711, that body stop 7 is fixing with the screw hole 512 of a distolateral section that is opened in flat back die 51.Top at the length direction of body stop 7 forms one group of spacing paw 72 that is people's finger-shaped bending, this quantity of organizing spacing paw 72 equates with the quantity in aforesaid one group of bend pipe chamber 511, and side direction is corresponding to the top in bend pipe chamber 511, corresponding to the top (shape shown in Fig. 1) of the end end in bend pipe chamber 511, organize spacing paw 72 by this and coordinate bend pipe chambeies 511 that the pipe 9 in the bend pipe process is seized on both sides by the arms or claimed to hook.
be fixed with the first hinge seat 121 of one group of on same straight line and each interval on aforesaid the first support foot 12, and form in the bottom of wheel frame 6, one first hinge 62 is arranged, the first hinge 62 matches with the first hinge seat 121, and pivotally connected by the first hinge axis 621.Top at wheel frame 6 is respectively that pivot is provided with one group of guide wheel 61 by the first guide wheel shaft 611 rotationally, and this group guide wheel 61 forms and one group of gradient relation or weighting platform rank relation that bend pipe chamber 511 is corresponding each other.Because bend pipe chamber 511 has four in the present embodiment, therefore one group of guide wheel 61 also should have four mutually.
in addition, be provided with one group of second hinge seat 131 on aforesaid the second support foot 13, and form at the base portion (bottom) of the length direction of standby wheel frame 8, there are one second hinge 82, the second hinges 82 to match with the second hinge seat 131, and pivotally connected by the second hinge axis 821.On the top of standby wheel frame 8, by the second guide wheel shaft 811, be respectively that to be provided with one group of standby guide wheel 81(the present embodiment be two to pivot rotationally).
refer to Fig. 2, the quantity in the bend pipe chamber 511 on the flat back die 51 provided is a pair of, and the quantity of the spacing paw 72 of body stop 7 is reduced to for Fig. 1 a pair of, and the shape of whole body stop 7 is configured to " r " shape that trends towards English alphabet.
<b TranNum="147">when will be to pipe 9 bending machining, one end of pipe 9 is held on one of them guide wheel 61 on wheel frame 6, body stop 7 now be in towards under position, the other end of pipe 9 has been shelved in the spacing paw arc-shaped cavity 721 of spacing paw 72, and one of them the bend pipe chamber 511 in one group of bend pipe chamber 511 is corresponding to the top of pipe 9.By the button on electric control box 16 operation, make 2 work of electric-powered mechanism drive bend pipe mould driving mechanisms 4 by the power drive mechanism 3 be in transmission connection with electric-powered mechanism 2, the 4th drive 42 by this bend pipe mould driving mechanism 4 drives bend pipe mould 5, thereby flat back die 51 is low moved, by 511 pairs, bend pipe chamber pipe 9 spinning, make pipe 9 bend to the shape that is similar to " C " font of arc transition or trend towards < the shape of font.The degree of crook of pipe 9 depends on the anglec of rotation size of bend pipe mould 5.</b>
as shown in the above description, the technical scheme that the utility model provides has overcome the drawback in the prior art, has completed the invention task, has embodied alleged technique effect in the superincumbent technique effect of applicant hurdle.
