Progressive die integrating small hole punching and forming

Abstract

The invention discloses a progressive die integrating small hole punching and forming, which is characterized in that: the progressive die comprises an upper die, a lower die, a male die, a female die and a secondary precision guide mechanism, wherein the male die is arranged in the upper die; the female die is arranged in the lower die; and the upper die and the lower die are connected together by secondary precision guide mechanism. The progressive die integrating small hole punching and forming provided by the invention performs punching operation on a punch press at a speed of 500 times per minute and can form a product by punching for one time without secondary processing; and meanwhile, when the die is used for processing small holes, the production efficiency is high, the cost is low, and a small punch pin is unlikely to be broken in a high-speed punching process and has a long service life.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automatic high-precision progressive mold integrating small hole punching and forming. Background technique [0002] At present, in the production process of multiple small holes with small spacing between holes, three processes can be used to achieve: 1) single-process die stamping forming process: use multiple sets of single-process dies to stamp the small holes, and then use a pair of single-process dies to form small holes. 2) Laser etching process: First, use a single-process mold or other molds to manufacture the required products into semi-finished products, and then use the high heat energy generated by the laser generator to etch the semi-finished products. Forming; 3) Drilling and forming process of high-speed drilling machine: drilling and forming small holes one by one. The common disadvantages of the above processes are: long process, low efficiency, high cost, poo...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing production process cannot satisfy the high-efficiency production of products with multiple small holes and very small hole spacing

[0005] Another object of the present invention is how to solve the problem of high production efficiency and low cost while ensuring that the small punch is not easy to break and has a long life in the high-speed stamping process
