Abstract

The utility model discloses a stamping composite die. The die comprises an upper die and a lower die, wherein a guide sleeve of the upper die is sleeved on a guide post of the lower die, a bottom hole punch is arranged in the center of the upper die, a flange hole punch is arranged at a position of the upper die, which is away from the bottom hole punch, the flange hole punch is sleeved by an upper punch die, and a first lower punch die, a lower punch die and a blanking die which correspond to the bottom hole punch, the flange hole punch and the upper punch die are arranged on the lower die. By the aid of the above mode, blanking, drawing, bottom hole punching, flange hole punching and edge cutting are compounded at one time, only a die is required, the blanking and the drawing are completed before the punching and the edge cutting, five processes are compounded sequentially, and requirements of high accuracy, low cost and high efficiency of modern production are met.

Description

A kind of punching-pressing composite mould

Technical field

The utility model relates to mould manufacturing field, particularly relates to a kind of punching-pressing composite mould.

Background technology

At present, for the bottom with aperture and the basic stamping procedure that has the once drawing spare of flange to be shaped be: blanking, pull and stretch, punching, side cut specifically have following four kinds of forming technology schemes:

(1) blanking, pull and stretch, punching, the single operation of side cut are shaped;

(2) blanking, punching are first compound, and pull and stretch, single operation of cutting edge are shaped again;

(3) blanking, pull and stretch are first compound, rush bottom outlet and side cut combined shaping again.

(4) blanking, pull and stretch, to rush bottom outlet first compound, cutting edge is shaped again;

By analyzing, scheme (1) mould structure is simple, but needs 4 secondary moulds, and efficient is very low, and can not produce high-precision stamping parts; Scheme (2), (3), (4) structure are slightly more complex, and need 2 pairs with mold, and accuracy and efficiency has largely and improves.These four kinds of schemes can not satisfy the requirement of modern production high accuracy, low cost, high benefit far away.
