Composite die for processing spring seat parts

Abstract

The invention belongs to the technical field of dies, and discloses a composite die for processing spring seat parts. The composite die comprises an upper die plate (15), a die handle (18), a punch-die II (12), an upper punching die (25), a punch-die I (6), a lower blanking die (8), a lower die plate (7) and a material discharge plate (10). The die handle (18) is fixedly connected with the upper die plate (15), a material striking block (26) is arranged in an inner hole of the punch-die II (12), the upper punching die (25) is positioned in the inner hole of the punch-die II (12), the punch-die I (6) and the lower blanking die (8) are arranged correspondingly to the punch-die II (12), a male die on the upper portion of the punch-die I penetrates a stepped through hole on the lower blanking die, and an inner hole of the punch die I (6) is formed correspondingly to the upper punching die (25). By the composite die, assembly quality and working efficiency of products are improved, and production cost of parts is reduced.

Description

technical field [0001] The invention belongs to the technical field of moulds, and mainly relates to a composite mold used for processing spring seat parts. Background technique [0002] In the traditional molding process of spring seat parts, three sets of molds need to be designed separately in the molding process of the parts. The structure is relatively simple and the manufacturing is easy. However, there are obviously the following disadvantages: First, the production efficiency is low, and the parts need to be replaced three times or on different presses to complete; second, in the three forming processes, especially the two processes of drawing and punching, it is necessary to replace the positioning surface twice to repeat Positioning, it is easy to cause the uneven height of the wall after the part is drawn, and the center of the punching hole is offset and misaligned; according to incomplete statistics, when the spring seat is formed with three sets of molds, the s...

Problems solved by technology

[0002] In the traditional molding process of spring seat parts, three sets of molds need to be designed separately in the molding process of the parts. The structure is relatively simple and the manufacturing is easy.

However, there are obviously the following disadvantages: First, the production efficiency is low, and the parts need to be replaced three times or on different presses to complete; second, in the three forming processes, especially the two processes of drawing and punching, it is necessary to replace the positioning surface twice to repeat Positioning, it is easy to cause the uneven height of the wall after the part is drawn, and the center of the punching hole is offset and misaligned; according to incomplete statistics, when the spring seat is formed with three sets of molds, the scrap rate of the part due to the offset of the center hole is only up to 20%

Although the value of each part is not high, the impact on production is very large

The third is that the wall height of the spring seat is difficult to be even after drawing, and the turning process has to be increased, the processing is complicated, and the production cycle is lengthened
