Abstract
The utility model relates to a turret punching die and assembling die material returning structure, belonging to a punching machine punching die and assembling die material returning device. The utility model discloses that a guide sleeve of a detachable material returning plate is fixed to the front end of the material returning structure, a lock pin is arranged in the body wall of the front end of the guide sleeve, the front surface of the lock pin contacts with the rear surface of the material returning plate elastically. The utility model processes the guide sleeve and the material returning plate in a fission way, to reduce the processing difficulty greatly; the center throughhole of the material returning plate can change according to the shape and size of a cutting edge of a punching head; because the structure of the material returning plate is simple, the prossesing cost is low and the manufacturing can be large; the material returning plate can be produced with metal material or engineering plastics respectively according the different requirements of punching plate material and the surface processing quality, to improve the surface processing quality the punching products; the lock pin adopts polyurethane pectin to produce, having a better elasticity, the rustiness problem does not exist, so the service life is long and replacing is easy and convenient.
Description
Technical field
The utility model relates to the material returned structure of punch press punch die patrix discharging device, particularly capstan head punch die patrix.
Background technology
The guide pin bushing and the stripper of the existing capstan head punch die patrix that uses in a large number are overall structure, and the difficulty of processing of the blind hole in the guide pin bushing is big, the manufacturing cost height; For adapting to the drift of different blade shapes and size, need to adopt different guide pin bushings; And can not require to adopt the stripper of different material making, thereby be unfavorable for improving the crudy of stamping-out product surface according to stamping-out sheet material material character and surface quality.
Summary of the invention
The purpose of this utility model provides a kind of material returned structure of capstan head punch die patrix, guide pin bushing and stripper split are processed, assembled, so that reduce the difficulty of processing of guide pin bushing, and can be different with size according to the drift blade shape, the different of stamping-out plate material and suface processing quality requirement select different strippers for use.
Technical solution of the present utility model is at the removable stripper that is fixed with of the front end of guide pin bushing, is provided with retaining pin, the rear end face Elastic Contact of the front end face of retaining pin and stripper in the body wall of the leading section of guide pin bushing.
Can be provided with annular groove on the hole wall of its front end face that keeps to the side of the endoporus of above-described guide pin bushing, form an inside annular convex between the front side wall of this annular groove and the guide pin bushing front end face, the close position of end face thereafter is provided with annular groove on the lateral surface of stripper, form an outside annular convex between the rear wall of this annular groove and the stripper rear end face, the annular convex of stripper is embedded in the annular groove of guide pin bushing, and the annular convex of guide pin bushing is embedded in the annular groove of stripper.
Can be provided with an open slot vertically on the body wall of the leading section of above-described guide pin bushing, be provided with a blind hole vertically in the body wall of the bottom of open slot, be provided with the elasticity retaining pin in this blind hole, the front end face roof pressure of retaining pin is on the rear end face of stripper.
Above-described retaining pin can be that front end face is the polyamine fat colloid pin that hemispherical, bar portion are the plum blossom cylindricality.
The central through hole of stripper of the present utility model can be circular hole, elliptical aperture, or polygonal hole.
Principle of the present utility model is that during assembling, with the annular groove on the inwall of the annular convex aligning guide pin bushing endoporus leading section on the rear end, the stripper outside, this moment, the rear end face of stripper was depressed retaining pin earlier.After the annular convex of the front end of guide pin bushing embedded the annular groove of stripper, the retaining pin elastic reset blocked the stripper outer shroud and realizes screens.Then drift is inserted guide pin bushing, rotate stripper, central through hole and drift cutting edge on the stripper are aligned, again drift is pushed the central through hole on the stripper, till the drift stop bit.During work, machine power promotes drift and presses down together with guide pin bushing, and stripper compresses the stamping-out plate, and drift continues downward stamping-out.After stamping-out finished, drift resetted through the stripper material returned.
The utility model has the advantages that because guide pin bushing and stripper split are processed, assembled, the difficulty of processing of guide pin bushing is reduced greatly; Central through hole on the stripper can be according to the difference of the shape and size of drift cutting edge and corresponding change; Because stripper is simple in structure, thereby processing cost is low, and be convenient to produce in enormous quantities; Stripper can according to stamping-out plate material and suface processing quality requires different and adopt metal material or engineering plastics to make respectively, is convenient to improve the crudy of stamping-out product surface; Retaining pin adopts polyamine fat colloid to make, and has elasticity preferably, does not have problem of rustiness, thereby long service life, and changes simple, convenient.
Description of drawings
Fig. 1 is an organigram of the present utility model;
Fig. 2 is an application examples schematic diagram of the present utility model.
The specific embodiment
According to Fig. 1, shown in Figure 2, the utility model by guide pin bushing 1, be installed in the stripper 2 of guide pin bushing 1 front end, the intraparietal retaining pin 3 that is installed in guide pin bushing 1 front end is formed.Be processed with annular groove 4 near on the hole wall of its front end face, the inside annular convex 5 of formation between the front side wall of annular groove 4 and guide pin bushing 1 front end face at the endoporus of guide pin bushing 1.Stripper 2 is circular, and the shape of its central through hole can be circular hole, elliptical aperture or polygonal hole, and its shape and size are decided according to the shape and size of drift 6 cutting edges.Position near rear end face on the lateral surface of stripper 2 is processed with the width annular groove 7 bigger slightly than the annular convex 5 of guide pin bushing 1.Form the width outside annular convex 8 slightly littler between the rear wall of annular groove 7 and stripper 2 rear end faces than the annular groove on the guide pin bushing 14.The annular convex 8 of stripper 2 is inlaid in the annular groove 4 of guide pin bushing 1, and the annular convex 5 of guide pin bushing 1 is inlaid in the annular groove 7 of stripper 2.Be processed with an open slot 9 vertically in the body wall of the leading section of guide pin bushing 1, the bottom of open slot 9 flushes with the rear wall of annular groove 4.In the body wall of the guide pin bushing 1 of the bottom of open slot 9, be processed with the blind hole of a diameter 3mm vertically, in blind hole, be fitted with retaining pin 3.Retaining pin 3 usefulness polyamine fat are made, and its front end face is semi-spherical shape, and its bar portion is the plum blossom post shapes.The front end face roof pressure of retaining pin 3 is on the rear end face of stripper 2.
