Abstract
The invention discloses a male die of a fine trimming die. The male die comprises a die shank, an upper die base, an upper padding plate, a punch-retainer plate, a punch and a scrap cutter, wherein the die shank, the upper die base, the upper padding plate, the punch-retainer plate and the punch are fixedly connected in sequence from top to bottom; the scrap cutter is located at the side of the punch and is fixedly connected to the punch-retainer plate; a small guide rod is also fixedly connected to the inside of the punch; and the lower end surface of the upper die base is fixedly connected with a guide sleeve and a limiting post. The male die disclosed by the invention and a female die matched with the male die form the fine trimming die mainly used for finely trimming parts; and the male die is reasonable in structural design, good in locating effect and high in machining precision.
Description
Technical field
The present invention relates to a kind of part forming mould structure, refer in particular to that a kind of accuracy is high, the male model of the refine Trimming Die of long working life.
Background technology
Reciprocating lever is as the vital part of sawing class instrument, and its accuracy of manufacture requires very high.The maximum feature of reciprocating lever punch process is exactly that material is thick, and the strength of materials is high, shearing area and shear dimension precision requirement high.The manufacture critical process of reciprocating lever part is blanking and refine.Be necessary to research and develop a kind of refine Trimming Die, be used for requiring that high part carries out finishing operations for the accuracy of manufacture.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose that a kind of deburring precision is high, the male model of the refine Trimming Die of long working life.
Technical solution of the present invention is achieved in that a kind of male model of refine Trimming Die, comprises die shank, upper bolster, upper padding plate, punch retainer, punch and scrap cutter; Described die shank, upper bolster, upper padding plate, punch retainer and punch are fixedly connected sequentially from top to bottom; Described scrap cutter is positioned at the side of punch, and is fixedly connected on punch retainer; Little guide post is also fixedly connected with in described punch; The lower surface of described upper bolster is fixedly connected with fairlead and limited post.
Preferably, described fairlead has four, is separately positioned on the corner of upper bolster.
Preferably, the lower end head of described scrap cutter is lower than the lower surface of punch.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Male model of the present invention and the master mold matched form refine Trimming Die, and be mainly used in the refine processing of part, its reasonable in design, good positioning effect, machining accuracy is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation of the male model of accompanying drawing 1 refine Trimming Die of the present invention.
Wherein: 1, die shank; 2, upper bolster; 3, upper padding plate; 4, punch retainer; 5, punch; 6, scrap cutter; 7, little guide post; 8, fairlead; 9, limited post.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The male model of refine Trimming Die of the present invention, as shown in Figure 1, comprises die shank 1, upper bolster 2, upper padding plate 3, punch retainer 4, punch 5 and scrap cutter 6; Described die shank 1, upper bolster 2, upper padding plate 3, punch retainer 4 and punch 5 are fixedly connected sequentially from top to bottom; Described scrap cutter 6 is positioned at the side of punch 5, and is fixedly connected on punch retainer 4; Little guide post 7 is also fixedly connected with in described punch 5; The lower surface of described upper bolster 2 is fixedly connected with fairlead 8 and limited post 9.
Further instruction, described fairlead 8 has four groups, is separately positioned on the corner of upper bolster 2, coordinates form guidance set with the lead on corresponding master mold.
Further instruction, the lower end head of described scrap cutter 6 is lower than the lower surface of punch 5.
The male model of the present invention program forms refine Trimming Die with the master mold matched, and its course of work is: be first connected to below suitable forcing press by die shank, and is installed on the table by die shoe; Workpiece to be processed is put into die, by hornblock location, location, workpiece is accurately located.Mould operationally, male molding member is descending with forcing press, when after punch and absorption surface, the scrap cutter of punch side is about to down the waste material excision of the edge of work simultaneously, then forcing press backhaul is up, and male molding member is and then up together, and the workpiece of deburring is released by stripper under the effect of recoil of spring power, finished work-piece is taken off, namely completes the finishing operations of a workpiece.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
