Abstract

The invention relates to a stamping die for improving processing precision. The stamping die comprises an upper die and a lower die which are in upper-lower layout. A male die is mounted on the upper portion of the upper die through bolts, and a U-shaped groove is formed in the bottom of the male die. A female die is mounted on the bottom of the lower die through bolts, and a U-shaped groove is formed in the top of the female die. Four stepped positioning rods are symmetrically arranged on the upper die, positioning tables are correspondingly arranged on the lower die, and each positioning table is provided with a stepped hole. Under the action of the positioning rods, positioning effect can be effectively improved, and a workpiece does not move during stamping, so that processing precision is effectively improved.

Description

A kind of diel that improves machining accuracy
Technical field
The present invention relates to mould applications, relate in particular to a kind of diel that improves machining accuracy.
Background technology
Diel, be in Cold Press Working, material (metal or nonmetal) is processed into to a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould be arranged on forcing press to exert pressure to material, makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.
Diel of the prior art is in the workpiece punching course, and limit effect is poor, easily is moved, and has reduced machining accuracy.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of diel that improves machining accuracy.
The present invention is achieved through the following technical solutions:
A kind of diel that improves machining accuracy, have and go to upper and lower the upper die and lower die of arranging, described patrix top is equipped with punch by bolt, the punch bottom is provided with the U-shaped groove, and the counterdie bottom is equipped with die by bolt, and the die top is provided with the U-shaped groove, be arranged with four backstays on described patrix, backstay is stepped stem, and described counterdie is provided with corresponding positioning table, in described positioning table, is provided with shoulder hole.
As the preferred technical solution of the present invention, described backstay and patrix are one-body molded.
As the preferred technical solution of the present invention, described positioning table and counterdie are one-body molded.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, under the effect of backstay, can effectively improve locating effect, and workpiece can not be moved when punching press, thereby effectively improves machining accuracy.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
Described a kind of diel that improves machining accuracy, have and go to upper and lower patrix 1 and the counterdie 2 of arranging, described patrix 1 top is equipped with punch 3 by bolt, punch 3 bottoms are provided with the U-shaped groove, and counterdie 2 bottoms are equipped with die 4 by bolt, and die 4 tops are provided with the U-shaped groove, be arranged with four backstays 5 on described patrix 1, backstay 5 is stepped stem, and described counterdie 2 is provided with corresponding positioning table 6, in described positioning table 6, is provided with shoulder hole 7.
Described backstay 5 is one-body molded with patrix 1, and described positioning table 6 is one-body molded with counterdie 2, is convenient to processing and manufacturing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
