Description

Straightening device for steel cable (wire rope)

The utility model belongs to a kind of specific purpose tool that metallic article is produced steel wire and steel wire rope aligning that is used for.

In order to make steel wire and steel wire rope have good straight line performance, on wire drawing machine and Bunching machine, be equiped with straightener usually.The kind of straightener has many, but what the most generally adopt is the roller type straightener, its action principle (as shown in Figure 1), be exactly with the orbit distortion of the steel wire after the moulding or steel wire rope 20 by running roller 19, its inner stress distribution is improved, so that reach the purpose of straightened condition.

According to TB4 type water tank drawbench and DTU, DTS type double twisting device and homemade LT160 that Italian GCR company is made.1---the result of use of several roller type straighteners (figure is omitted) that 19/165 type wire drawing machine is disposed is observed, the part that all comes with some shortcomings to some extent, it is not good mainly to show as complex structure, volume bulkiness, manufacturing cost height, result of use.

The utility model proposes at the existing weak point of above-mentioned straightener, and purpose is roller type steel wire (rope) straightener of a kind of novel structure of design, easy to use, dependable performance.

Feature of the present utility model is: upper body and following body that straightener mainly is connected by the alignment pin of being furnished with nut constitute, be equipped with between the body up and down be enclosed within play on the alignment pin separate about the spring of body effect; Bearing is contained on the same plane of body up and down respectively with movable little axle and fixing little axle, the adjustment of volume under pressure is by the little axle realization of passing activity up and down of spring, core bar and screw, the not activity supporting point of this spring is located at down in the body and by core bar centering, and core bar is to lead with the screw that is fixed on down on the body and have a centre bore.

Fig. 1 is the operation principle schematic diagram of roller type straightener; Fig. 2 is a front view of the present utility model, and Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the version I that A-A analyses and observe among Fig. 2, is used for upright dress; Fig. 5 is A-A analyses and observe among Fig. 2 version II, be used to put down, upright dress.

Describe structure of the present utility model and using method in detail below in conjunction with accompanying drawing:

Folding, guiding and location between upper body 2 of the present utility model and the following body 8 is with running through

body

2,8 up and down and being furnished with the alignment pin 7 of nut 1 and being contained in up and down between the

body

2,8 and the spring 6 that is enclosed within on the alignment pin 7 is finished stretching out the end of thread outside the body, when upper and

lower body

2,8 merges, spring 6 is closed in the body, as shown in Figure 2; The bearing 4,4a that cylindrical has a groove is contained on the same plane of

body

2,8 up and down respectively by little axle 5 of activity and fixing little axle 15, the adjustment of the volume under pressure H of bearing 4 is radially to realize on the face of cylinder of the little axle 5 of passing activity up and down in the orientation by the screw 3 that is contained in down spring 13, the T-shape core bar 12 in the body 8 and be connected on the upper body 2, shown in Fig. 2 and 4 and with reference to Fig. 1; The screw 11 that is fixed on down on the body 8 and has a centre bore is to be used for support spring 13 and spring 13 is played core bar 12 guiding of centering effect, and makes it easy to loading and unloading, as shown in Figure 2.

For the ease of the utility model paperback (be body bearing is housed the plane upwards) operation under the situation, the structure of Fig. 4 is changed a little, become the form of Fig. 5, promptly the plate 17 that is connected with trough of belt on the opposite plane of bearing with screw 18 is housed at upper body 2 and following body 8, the nut 16 that is used for the little axle of fastening activity 5 sinks to the groove of plate 17, and it can move and do not rotate with the little axle 5 of activity and along its radial orientation; The afterbody of movable little axle 5 changes cylindrical annular knurl form into, can be without the instrument direct control.

Adopt following structure also can realize the purpose of this utility model:

(1) concentric holes that has step being processed in the position at screw 11 places of following body 8 directly leads and support springs 13 to core bar 12.

(2) spring 13 pass down body 8 not activity supporting point be placed on other part, such as drop on the external backing plate of following body 8 on.

(3) the movable little axle 5 of two kinds of forms exchanges use among Fig. 4 and Fig. 5.

(4) according to the specification and the speed of service of being rectified steel wire rope 20, the roller that bearing 4,4a is changed into general type uses.

(5) according to the installation and the service condition of straightener, alignment pin 7 tunes are used.

The utility model can also can found dress by paperback, descends body 8 to be fixed on the relevant position of wire drawing machine or Bunching machine it with screw during use, and concrete operation method is as follows:

(1) steel wire (rope) is installed: while loose nut 1, upper body 2 is subjected to the thrust of spring 6 to separate (one-tenth appropriate gap) with following body 8 voluntarily, in the stretching race of putting into down row's bearing 4a of steel wire (rope) (referring to Fig. 1), screw nut 1 more simultaneously then, make that

lower body

2,8 merges on it.

(2) steel wire (rope) linearity adjustment: after finishing steel wire (rope) and being installed, adjust the volume under pressure H that respectively organizes bearing 4 more respectively.Earlier nut 10,16 and the packing ring 9,14 with the movable little axle 5 of institute's accent is lax, when the need volume under pressure reduces, revolves screw 3 on pacifying slowly, and spring 13 opened naturally and drove that core bar 12 makes movable little 5 and upper bearing (metal) 4 and screw 3 rise synchronously this moment; When the need volume under pressure increases, but backspin screw 3, and the resistance that overcomes spring 13 moves down movable little axle 5, upper bearing (metal) 4 and core bar 12.

It is pointed out that the adjustment order of respectively organizing bearing 4 volumes under pressure generally interts carries out, and also will constantly observe the straight line situation of being transferred steel wire (rope) simultaneously, when thinking when reaching perfect condition little 5 of final fastening activity.In ordinary production, only need to finish steel wire (rope) and be installed and get final product according to the program of method of operating (1).

The utility model is compared with front described straightener, has following characteristics:

(1) simple in structure, easy manufacturing, main member of the present utility model is upper body 2 and lower body 8, folding between the two, guiding and location have only used common dowel device 1,6,7 to realize, the method that the back board device guiding that adopts than aforementioned straightener and eccentric mechanism carry out folding, location is particularly simple. The geometry of each parts is also than standard, so processing and manufacturing is all very convenient in addition.

(2) rational in infrastructure, volume is very little, design of the present utility model has made full use of the locus of

body

2,8 up and down, total is more become rationally and compact.As not resembling the straightener of aforementioned DTU machine, the not activity supporting point of spring 13 (referring to an end points place opposite with movable little axle 5) is not located in the body at adjustable bearing split bearing place, but be chosen in down dexterously within the body 8, thereby solved the working depth of spring 13 and the contradiction between the stress deformation effectively, also dwindled the volume of straightener simultaneously.The centering of core bar 12 has been arranged in addition, just guaranteed that also spring 13 is not offset on any situation.

(3) easy to operate, dependable performance, except that the fastening and lax use one easy screwdriver of the little axle 5 of activity, all the other positions do not need just can arbitrarily adjust by means of instrument.After the little axle of activity 5 and alignment pin 7 were locked, straightener had just formed a firm integral body, so running precision is highly stable.
