Description

The spring forming machine push device

Technical field

The present invention relates to a kind of device that pushes, relate in particular to a kind of device that pushes of spring forming machine.

Background technology

General spring forming machine all has in order to push wire rod and wire rod is shaped to the device that pushes of spring, the technology of spring forming is with a feed mechanism wire rod to be sent into the spring forming machine, utilization pushes device and wire rod is curled and the formation spring, utilizes cutter that wire rod is cut off to finish the technology of spring forming at last again; Wherein, the effect that pushes device is the wire rod of linearity is shaped to the spring of the shape that curls, and the spring forming machine normally has and lays respectively at two of spring forming machine two respective side and push assembly; Adjust the circle footpath size that this two position that pushes assembly can determine formed spring.

The device that pushes of existing spring forming machine generally includes a sliding seat and is slidably connected to one of sliding seat and pushes the unit, can make oblique one-dimensional linear relative to the spring forming machine and move so that push the unit, adjust the line footpath size of formed spring, adjust the free degree deficiency that makes the spring forming machine determine spring wire footpath size but only can move with oblique one-dimensional linear, inconvenient in the adjustment.

Therefore just develop the device that pushes that another kind of spring forming machine, its improvement be except push the unit relatively the spring forming machine do the oblique movement, push device also relatively the spring forming machine do the vertical linear motion of one dimension direction, adjust the position that pushes the unit and still dislike not enough slightly but the linearity of utilizing this two direction moves, and push only spring forming machine do position adjustment among a small circle relatively of unit.In addition, two of existing spring forming machine push the unit and can't be independently push the unit as two dimensional motion adjustment and go out the position of bobbin with respect to the spring forming machine, cause in the technologic flexibility ratio of spring forming comparatively not enough.

So, how to improve aforesaid problem points, the problem that promptly becomes the present invention and studied.

Summary of the invention

A purpose of the present invention is to provide a kind of device that pushes of spring forming machine, and this pushes assembly and can do at random vertically, laterally move with respect to board by first transmission mechanism, second shaft transmission respectively, adjusts the free degree that pushes assembly to increase.

To achieve the above object, the invention provides a kind of device that pushes of spring forming machine, these spring forming facility have a board, this pushes device and comprises one first shaft transmission, one second shaft transmission and one pushes assembly, wherein, this first shaft transmission comprises one first brake that is fixed in described board, be subjected to one first driving screw of this first rotation that brake drives and be bolted in this first driving screw and can make linearly moving one first sliding seat with respect to described board, this second shaft transmission comprises one second brake that is fixed in this first sliding seat, be subjected to one second driving screw of this second rotation that brake drives and be bolted in this second driving screw and can make linearly moving one second sliding seat with respect to this first sliding seat, this pushes assembly and is fixed in this second sliding seat, this push assembly by this first shaft transmission and this second shaft transmission and can with respect to described board do vertically and laterally two dimension move.

To achieve the above object, the present invention system provides a kind of device that pushes of spring forming machine, these spring forming facility have a board and a spring wire to send axle, this pushes device and comprises a pair of first shaft transmission, a pair of second shaft transmission and a pair of assembly that pushes, wherein, should to first shaft transmission be formed at respectively described spring wire send shaft centre line on, following both sides, this first shaft transmission comprises one first brake that is fixed in described board, be subjected to one first driving screw of this first rotation that brake drives and be bolted in this first driving screw and can make linearly moving one first sliding seat with respect to described board, should comprise one second brake that is fixed in this first sliding seat respectively to second shaft transmission, be subjected to one second driving screw of this second rotation that brake drives and be bolted in this second driving screw and can make linearly moving one second sliding seat with respect to this first sliding seat, should be individually fixed in this second sliding seat to pushing assembly, this can be done vertically with respect to described board and laterally two-dimentional moving second shaft transmission by should and being somebody's turn to do first shaft transmission respectively independently to pushing assembly system.

The present invention is compared to the effect that prior art reached, solving existing spring forming machine only can utilize the linearity of a direction to move the shortcoming that reaches the adjustment that pushes device, by vertically moving and horizontal two dimension moves, the convenient adjustment pushes assembly and sends the position of axle with respect to board and spring wire, improves the flexibility ratio of spring forming technology; In addition, move simultaneously independently of each other pushing assembly by this, and can do moving of different azimuth, plasticly go out the comparatively complexity or the spring of 3D shape; Moreover first shaft transmission and second shaft transmission can increase the orientation that pushes assembly and the mobile variability of angle; Moreover moving to linear of first and second shaft transmission moved, thus can reach location more accurately, and also quite simple and easy in the operation.At last, can separate independent do to move this also can control pushing assembly by computer, control this respectively to pushing the difficulty that assembly can significantly improve the flexibility ratio of technology and reduce spring forming with computer.
