Quick-change device special for punch and using method of quick-change device

Abstract

The invention relates to a quick-change device special for a punch and a using method of the quick-change device. The device comprises an upper die and a lower die, the upper die is provided with a punch, a movable assembly for driving the punch to move longitudinally and a first guide groove corresponding to the punch, and the lower die is provided with an insert corresponding to the punch. Due to the fact that a movable assembly is additionally arranged, the position of the punch can be adjusted, the use state is adjustable, so that a set of dies can be used for completing the production ofmultiple similar product, the device is good in applicability and is suitable for production of multiple similar products, the production efficiency can be greatly improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of metal stamping dies, and more specifically, to a special quick-change device for punches and a method for using the same. Background technique [0002] With the increasingly fierce competition in global mold technology, the production cost of metal stamping molds has become the core issue that manufacturers need to solve. In the field of automotive stamping dies, large dies weighing dozens of tons are often seen. These large dies are expensive and have a long production cycle, and cannot be replaced quickly. In the existing continuous die production, the upper die is often fixed with a variety of punches for multi-station processing, and the punch and the upper die are directly fixed together. The height of the punch is not variable, and it is always in a punching state. , it will cause great inconvenience in the production of multiple similar products. For example, product A has only one punching proces...

Problems solved by technology

In the field of automotive stamping dies, large dies weighing tens of tons are often seen. These large dies are expensive and have a long production cycle, and cannot be replaced quickly

In the existing continuous die production, the upper die is often fixed with a variety of punches for multi-station processing, and the punch and the upper die are directly fixed together. The height of the punch is not variable, and it is always in a punching state. , it will cause great inconvenience in the production of multiple similar products. For example, product A has only one punching process less than product B. When producing product A, the punch must be removed before production, resulting in In order to be unable to produce multiple products with the same set of molds, the applicability of the molds is poor, and the large molds are bulky, time-consuming to disassemble and assemble, and the punching machine is also in an idle state and cannot be processed, which greatly reduces the production efficiency and leads to high production costs.
