Abstract

The invention aims to better improve the process flow of punching new products, meet the requirements of customrs for punching products, shorten the period, reduce the cost and improve the efficiency.The invention provides a special rectangular punching mechanism which comprises an upper die assembly and a lower die assembly, wherein the lower die assembly is right under the upper die assembly; the upper die assembly comprises an upper die seat 11, an upper backing plate 12, an upper clamping plate 13, a discharging backing plate 14, a discharging plate 15, a punch 16, a nitrogen pressure pump 17 and a nitrogen spring 18; the lower die assembly comprises a lower die plate 21, a lower backing plate 22, a lower die seat 23, a female die 24, a lower ejector rod 25, a blanking device 26, a guide block 27 and a floating block 28; the punch 16 comprises a punch seat 161 and a punch top 162; the punch seat 161 extends downwards out of the punch top 162; the punch seat 161 is wider than the punch top 162; and the angle between the wedge surface at the junction of the punch top 162 and the punch seat 161 and the punch top 162 is 30 degrees.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to the field of high-precision cold stamping. Background technique [0002] High quality, short delivery time, and low cost are the eternal requirements of customers for product parts. With the progress of the times, the information industry and electronic components are also developing and updating rapidly, and the requirements for the stamping process are getting higher and higher. The ordinary stamping process in the past can no longer meet the requirements of new products. The previous punching process can be completed with wire cutting punch, punching die and ordinary grinding. However, it cannot meet the requirements for special-shaped punching and edge-lapping. [0003] A Chinese invention patent has been published, publication number: CN105363816B, patent name: a micro-hole stamping forming process, application date: 20151204, which discloses a technology in the field ...
