Abstract
The utility model discloses a protection device effectively preventing a punch from being broken. The protection device comprises the punch, one end of the punch is provided with an adaptor, one end of the adaptor is arranged into a plunger chip, a discharging plate is arranged on one side of the plunger chip, one end of the discharging plate is arranged into a guide layer, the other end of the discharging plate is arranged into a material-removing layer, and the width of the material-removing layer is larger than that of the guide layer. The protection device can effectively enable waste materials to fall off, does not enable the waste materials to be taken to the upper portion during an actual processing procedure, effectively avoids breaking of the plunger chip caused by an undersize gap, effectively improves the phenomenon that plunger chips are replaced frequently in an original punching process, increases using flexibility, and is novel in design and easy to popularize and apply.
Description
Technical field
The utility model relates to the stamping Die Design manufacture field, particularly relates to a kind of protector that prevents that effectively punching pin from disconnecting.
Background technology
Drift also is punch, patrix, formpiston, red needle etc., and drift is divided into A type drift, T-shaped drift, special-shaped plunger chip.Drift is mounted in the metal parts in the diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.Mold and punching head generally adopts high-speed steel and wolfram steel etc. as material, high-speed steel drift and wolfram steel drift etc. are arranged, and high-speed steel is the most frequently used material, commonly used have CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., the wolfram steel material generally is used on the punching and shearing die of having relatively high expectations, the precision of at present domestic professional production manufacturer production drift all can reach ± 0.002mm, with true treasured in the quality that adds the punching in man-hour, in the processing of the five metals in modern times or machining, cooperate use of punching die, also improve the efficient of producing.
Yet, for some tiny drifts, in process, use repeatedly, because waste material is too much, so that the gap smaller in process, thereby cause drift be easy to sprain disconnected, thereby interrupt production, change frequently drift, to such an extent as to reduced the efficient of producing, and drift easily disconnected reason be, in the process of design since drift and stripper to enter the gap of piece smaller, although easily broken drift has all increased reinforcement, also keeping away unavoidably in process of production the punch holder break flour brings up, so that entering the break flour of being brought up in the gap of piece an actor's rendering of an operatic tune, drift and stripper be stuck in the inside, more and more to the waste material that makes the inside, thus cause disconnecting, the flexibility ratio of using is little, is unfavorable for promoting and using.
In sum, for the defective of prior art, need especially a kind of protector that prevents that effectively punching pin from disconnecting, to solve the deficiencies in the prior art.
The utility model content
For in the prior art punching pin being disconnected easily, and very large defective arranged in the process of practical application, the utility model proposes a kind of protector that prevents that effectively punching pin from disconnecting, simple in structure, easy to make, can effectively waste material be come off, can be with the scrap band in not top, the fracture of effectively having avoided drift to cause owing to the gap is too small addresses the deficiencies of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of protector that prevents that effectively punching pin from disconnecting, comprise punching pin, one end of described punching pin is provided with adapter, the one end is set to drift, described drift one side is provided with stripper, one end of described stripper is set to guide layer, and its other end is set to take off the bed of material, takes off the width of the bed of material greater than the width of guide layer.
Further, be provided with pilot hole, the large 0.04mm of width of the Width punching pin of described pilot hole in the middle of the described guide layer.
Further, the described below of taking off the bed of material is provided with the waste material receiving magazine.
Further, the diameter of described punching pin is 2mm, and the diameter of drift is 0.5mm.
Further, the shape of described drift is tapered.
The beneficial effects of the utility model are: this apparatus structure is simple, easy to make, so that the technique of stripper and design are more reasonable, can effectively waste material be come off, in the process of reality, scrap belt is gone in top, the fracture of effectively having avoided drift to cause owing to the gap is too small, effectively improve the original phenomenon of changing frequently drift of in punch process, managing, promoted the efficient of producing, also effectively saved production cost, increased the flexibility of using, modern design is a kind of good design, is easy to promote and use.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a kind of structural representation that effectively prevents the protector that punching pin disconnects of the utility model.
100-punching pin among the figure, the 110-adapter, the 120-drift, the 300-stripper, the 310-guide layer, 320-takes off the bed of material, 330-pilot hole, 340-waste material receiving magazine.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of protector that prevents that effectively punching pin from disconnecting, comprise punching pin 100, one end of described punching pin 100 is provided with adapter 110, the one end is set to drift 120, described drift 120 1 sides are provided with stripper 300, one end of stripper 300 is set to guide layer 310, and its other end is set to take off the bed of material 320, takes off the width of the bed of material 320 greater than the width of guide layer 310.
In addition, be provided with pilot hole 330 in the middle of the described guide layer 310, the large 0.04mm of width of the Width punching pin 100 of described pilot hole 330, and the below of taking off the bed of material 320 is provided with waste material receiving magazine 340.The diameter of punching pin 100 is 2mm, and the diameter of drift 120 is 0.5mm.The shape of drift 120 is tapered.
Present embodiment is in the process of using, punching pin 100 is in processing, adapter 110 connects with machine, drift 120 passes through first the guide layer 310 of stripper 300, at last by taking off the bed of material 320, owing to take off the width of the bed of material 320 greater than the width of guide layer 310, waste material just can not take the top to from guide layer 310 like this, just can determine the gap between drift 120 and the stripper 300, effectively avoid break flour that drift 120 is stuck, strengthen the service life of drift 120.
Based on above-mentioned, the beneficial effect of present embodiment is simple in structure, easy to make, so that the technique of stripper and design are more reasonable, can effectively waste material be come off, in the process of reality, scrap belt is gone in top, and the fracture of effectively having avoided drift to cause owing to the gap is too small has effectively improved the original phenomenon of changing frequently drift of managing in punch process, promoted the efficient of producing, also effectively save production cost, increased the flexibility of using, modern design, be a kind of good design, be easy to promote and use.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
