A punching die for rear suspension mounting bracket

Abstract

The invention relates to a punching die of a rear suspension installation bracket. The punching die comprises an upper die and a lower die, wherein the upper die comprises an upper die plate, an upper padding plate, an upper fixing plate, a punching head, a pressing plate and a male die, the lower die comprises a female die insert, a female die, a lower padding plate, a lower die plate, a right L-shaped locating block and a left L-shaped locating block, an elastic element is embedded in the left side of the upper fixing plate, the lower end of the elastic element is connected with the pressing plate, the punching head is clamped in the middle part of the upper fixing plate and the pressing plate, the upper end of the male die is fixedly connected with the middle lower part of the pressing plate, the lower end of the punching head penetrates through the male die, the female die is installed in the female die insert, the left L-shaped locating block is fixed at the left rear part of the upper part of the male die and the male die insert, and the right L-shaped locating block is fixed at the right front part of the upper part of the male die and the male die insert. The punching die of the rear suspension installation bracket has the advantages of reasonable structure design, convenience in control, high punching efficiency and the like, and the locating size of a to-be-punched part is guaranteed, so that the repair rate is reduced, the part is automatically separated, and convenience is provided for the use of an operator.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a punching die for a rear suspension mounting bracket. Background technique [0002] The structural features of the rear suspension mounting bracket commonly used in automobiles include the mounting surface and the side block. The middle part of the mounting surface needs to be punched so as to be used for positioning and connection with other parts on the automobile. When using the existing punching die to punch it, because the punching process is after the flanging of the side stop, and the structural characteristics of the side stop are not convenient for lateral positioning, it is easy to produce positioning errors, resulting in punching The dimensional accuracy of the hole is poor, which affects the installation and use of the rear suspension mounting bracket. The position of the hole needs to be corrected repeatedly to meet the use requirements. The repair rat...

AI Technical Summary

Problems solved by technology

The mold has a simple and reasonable structural design, fast opening and closing speed of the stamping die, high processing efficiency, compact structural design, small size, and is convenient for mold installation and management, but the mold is not suitable for rear suspension mounting brackets. The reason is that the structural characteristics of the rear suspension support and the rear suspension mounting bracket are different, and the parts that need to be punched are different, and the positioning of the rear suspension support is relatively simple. This mold can meet the positioning requirements, and the installation of the rear suspension mounting bracket Positioning is difficult, and the positioning size is difficult to guarantee
