Abstract
The invention discloses a female die body of a trimming die for fine trimming. The female die body comprises a lower die seat, a female die fixing plate, a female die and an unloading plate. The female die fixing plate is fixedly connected to the lower die seat. The female die is fixedly connected to the female die fixing plate. The unloading plate is sleeved with the female die. The lower end face of the unloading plate is connected with the lower die seat in the manner that force transfer rods and springs penetrate the female die fixing plate. The upper end face of the female die fixing plate is further fixedly connected with locating blocks. The lower die seat is further fixedly connected with guide columns and limiting columns. The trimming die for fine trimming is formed by the female die body and a matched male die body, the trimming die for fine trimming is mainly used for fine trimming machining of a part, and the female die body 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 master mold 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 master mold of the refine Trimming Die of long working life.
Technical solution of the present invention is achieved in that a kind of master mold of refine Trimming Die, comprises die shoe, die block, die and stripper; Described die block is fixedly connected on die shoe; Described die is fixedly connected on die block; Described stripper is set in die; The lower surface of described stripper, by transmission rod and spring, is connected with die shoe through die block; The upper surface of described die block is also fixedly connected with locating piece; Described die shoe is also fixedly connected with lead and limited post.
Preferably, described lead has four groups, is separately positioned on the corner of die shoe.
Preferably, described locating piece has two pieces at least.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Master mold of the present invention and the male model 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 master mold of accompanying drawing 1 refine Trimming Die of the present invention.
Wherein: 1, die shoe; 2, die block; 3, die; 4, stripper; 5, transmission rod; 6, spring; 7, locating piece; 8, lead; 9, limited post.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The master mold of refine Trimming Die of the present invention, as shown in Figure 1, comprises die shoe 1, die block 2, die 3 and stripper 4; Described die block 2 is fixedly connected on die shoe 1; Described die 3 is fixedly connected on die block 2; Described stripper 4 is set in die 3; The lower surface of described stripper 4, by transmission rod 5 and spring 6, is connected with die shoe 1 through die block 2; The upper surface of described die block 2 is also fixedly connected with locating piece 7; Described die shoe 1 is also fixedly connected with lead 8 and limited post 9.
Further instruction, described lead 8 has four groups, is separately positioned on the corner of die shoe 1, coordinates form guidance set with the fairlead on corresponding male model.
Further instruction, described locating piece 7 has two pieces at least, is symmetrical arranged above die, for fixing part to be processed, also can arrange more locating piece according to part shape, guarantee to locate more accurately.
The master mold of the present invention program forms refine Trimming Die with the male model 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.
