Compound die capable of reducing blanking force for thick material connecting card

Abstract

The invention relates to the technical field of stamping machining, and specifically provides a compound die capable of reducing blanking force for a thick material connecting card. The compound die comprises an upper die part and a lower die part, wherein the upper die part comprises an upper die base, an upper cushion plate and an upper die fixing plate arranged sequentially from top to bottom,and a first spring component is further arranged in the upper die part; the lower die part comprises a discharging plate, a lower die fixing plate and the a lower die base arranged sequentially from top to bottom, a convex die and a concave die are embedded in the discharging plate, and a second spring component is further arranged in the lower die part; the lower surface of the upper die fixing plate is provided with a concave die plate; the lower surface of the concave die plate is provided with a plurality of bosses; a returning component is arranged in the concave die plate; and a punch penetrates through the upper die fixing plate and the returning component. By means of the compound die capable of reducing blanking force for the thick material connecting card, the blanking force andthe noise decibel generated by the stamping operation can be reduced, and the service life of the die is prolonged; and the costs of labor and material can be reduced, the production efficiency of products is improved, and parts can be produced quickly at one time.

Description

technical field [0001] The invention relates to the technical field of stamping processing, and more specifically, provides a composite mold for reducing punching force of a thick-material connection card. Background technique [0002] There are various styles and structures of hardware accessories circulating in the market. Among them, there is a siphon type roof rainwater drainage suspension system accessory connection card, which is used together with common pipe clips and is in great demand. At present, the molds used for parts generally use large punching machines, the cost of artificial water and electricity is relatively high, the noise is large, and the loss of the machine tool is large; during the punching process, the punch is easy to be broken or chipped; The material parts are not flat, and large burrs are prone to appear; the typing process is not combined with the blanking and punching, and two sets of dies are required for production, and the production effic...
