Side punching die with discharging function for upper arm bracket

Abstract

The invention discloses a side punching die with a discharging function for an upper arm bracket. The side punching die comprises an upper die seat, a pin, a lengthened screw, a guide sleeve, a guidepost, a lower die seat, an upper sliding block, a lower sliding block, a lower sliding block base assembly, a baffle, a spring, a double-layer nut, a pressing plate, a screw, an upper die backing plate, a punch fixing seat, a hole-punching punch, a female die fixing seat, a positioning block, a discharging spring, material-pressing rubber, a backing plate and a lower die backing plate. By arranging the punch fixing seat and the hole-punching punch, holes are punched at two sides simultaneously, so that the accuracy of the holes is effectively guaranteed; by arranging the discharging spring, the discharging spring ejects a stamped part after punching, and thus the production efficiency and the product quality are greatly improved; and by arranging the material-pressing rubber, when a workpiece is punched, the fixing effect of the workpiece can be guaranteed, and the workpiece can be prevented from being crushed.

Description

technical field [0001] The invention relates to the technical field of cold stamping dies, in particular to a side punching die with unloading for an upper arm bracket. Background technique [0002] The upper arm bracket is a component on the chassis of the rear axle of the car. There are connecting holes and arcs on both sides of the upper arm bracket, which are important parts for connecting the body and the rear axle. Therefore, the dimensional accuracy requirements for machining holes on both sides are relatively high. [0003] The traditional processing method is in the form of simple mold or drilling. The processing method of drilling has poor processing accuracy, poor hole consistency, and the concentricity of the holes on both sides cannot meet the design requirements, which affects the assembly quality. Simple die punching. After side punching, the stamping part is stuck on the punch holder, which is inconvenient to take out. The labor intensity of the workers is h...

Problems solved by technology

[0003] The traditional processing method is in the form of simple mold or drilling. The processing method of drilling has poor processing accuracy, poor hole consistency, and the concentricity of the holes on both sides cannot meet the design requirements, which affects the assembly quality. Simple die punching. After side punching, the stamping part is stuck on the punch holder, which is inconvenient to take out. The labor intensity of the workers is high and the production efficiency is low.
