Abstract

The utility model discloses a punch mold for thin material processing. An upper mold (2) is fixed on bottom of upper die holder (1), a die cavity formed by the upper die holder (1) and the upper mold (2) is filled with polyurethane mold (3), lower plane of the mold (3) is aligned with that of the die cavity of the upper mold (2), and a section mold (6) is placed on a working face (4) of a lower die holder (5). The utility model can produce thin material products of smooth edge and excellent quality via common press. At the same time, the utility model also improves utilization rate of equipment, saves raw materials and increases productivity.

Description

The stamping die that is used for thin material processing

Technical field

The utility model belongs to the diel field, particularly a kind of stamping die that is used for thin material processing.

Background technology

At present, need the thin material product of production lot of materials thickness in the industrial production less than the special type of 0.5mm, as slim pad etc., if this thin material product is directly used the forcing press punching press when production and processing, because material is too thin, the edge out-of-flatness of the product of producing that comes out, centre also can form local concavo-convex, therefore can not come direct processing thin material product with forcing press.Adopt the manual method for processing of pincers worker, though can ensure the quality of products, because process time is longer, production efficiency is low, and the qualification rate of product is relevant with workman's skills involved in the labour, and its qualification rate fluctuation is big.

Summary of the invention

The utility model purpose is, a kind of stamping die that is used for thin material processing is provided, and it adopts traditional stamping technology processing thin material product, the product percent of pass height is arranged, the advantage that production efficiency height and mould are simple and easy to make.

The purpose of this utility model is achieved like this:

The below of upper bolster is provided with patrix, filled polyurethane mould in the die cavity that upper bolster and patrix constitute, and the lower plane of polyurethane mould flushes with the lower plane of last model cavity, lays pattern on the working face of die shoe, and the diameter of its pattern is less than the die cavity diameter.

Owing to adopted such scheme, during with the product of this stamping die punching production thin material, because polyurethane mould has certain toughness, when patrix carries out punching press, because the diameter of pattern is less than the die cavity diameter, then according to the shape of the pattern formation product that is stamped, raw material are stressed evenly in the punching course for raw material, local concavo-convex phenomenon in the middle of product can not produce, product meets technological requirement.

This stamping die is used to process the thin material of thickness less than 0.5mm, and it is smooth to process its edge of thin material product, and quality is good, and the product percent of pass height has improved utilization rate of equipment and installations simultaneously, has saved raw material, has alleviated labour intensity.

Description of drawings

Fig. 1 is a structure cutaway view of the present utility model;

In the accompanying drawing, 1 is upper bolster; 2 is patrix; 3 is the polyurethane mould; 4 is the counterdie working face; 5 is die shoe, and 6 is pattern.

The specific embodiment

Referring to Fig. 1, upper bolster 1 below is provided with patrix 2, and patrix 2 is fixed on the upper bolster 1 by screw.Filled polyurethane mould 3 in the die cavity of upper bolster 1 and patrix 2, polyurethane can directly be filled in the die cavity of patrix 2.The lower end of polyurethane mould 3 flushes with the lower plane of an actor's rendering of an operatic tune 2.Lay pattern 6 on the working face 4 of die shoe 5, the diameter of pattern 6 is less than the die cavity diameter, and pattern adopts mould steel such as T10A or Cr12MoV to make.

The shape of polyurethane pattern 6 is the shape setting of processing parts as required.

To produce ring washer is that example describes the utility model.

On the counterdie working face 4 that is connected as a single entity with die shoe 5, lay the pattern 6 of ring washer, raw material are placed on the pattern 6, start stamping machine, upper bolster 1 drives patrix 2 and moves downward, because filled polyurethane mould 3 has the effect of certain compensator or trimmer pressure in the die cavity, and the diameter of pattern 6 is less than the die cavity diameter, and patrix 2 can stamp out raw material the ring washer product, the packing ring Internal and external cycle edge of gained is smooth, meets technological requirement.

Claims

1, a kind of stamping die that is used for thin material processing, comprise upper bolster (1) and die shoe (5), go up and be provided with patrix (2) in the bottom surface of die holder (1), it is characterized in that: filled polyurethane mould (3) in the die cavity that upper bolster (1) and patrix (2) constitute, lay pattern (6) on the working face (4) of die shoe (5).

2, stamping die according to claim 1 is characterized in that: the lower plane of described polyurethane mould (3) flushes with the lower plane of patrix (2) die cavity.
