A polymer sheet punching device for the production of automobile rear axle housing

Abstract

The invention discloses a polymer plate punching device for the production of automobile rear axle housing, comprising a base and a punching cylinder, a placing groove is arranged on the base, a liquid storage groove is arranged in the center of the placing groove, and the liquid storage groove is sealed by an elastic film , The bottom of the liquid storage tank is fixed with a conductive plate, the elastic film is provided with a conductive net, the punching cylinder is fixed with a mounting cylinder, the bottom of the mounting cylinder is fixed with a punching rod, and the outer wall of the mounting cylinder is fixed with static electricity. The electrorheological fluid hardens to support the plate, the punching cylinder drives the punching rod to descend to punch the hole, when the punching rod descends, the negative charge accumulated at the tip of the punching rod makes the negative charge on the conductive net discharge. Open, so that the electrorheological fluid at the punching position is softened, which is convenient for the punching operation. At the same time, the electrorheological fluid around the punching position is in a hardened state, supporting the plate and avoiding the deformation of the punching position.

Description

technical field [0001] The invention relates to the technical field of auto parts processing devices, in particular to a punching device for polymer plates used in the production of automobile rear axle housings. Background technique [0002] The rear axle of the car refers to the rear drive shaft component of the vehicle power transmission. It consists of two half-axles, which can implement the differential motion of the half-axles. At the same time, it is also a device used to support the wheels and connect the rear wheels. For a vehicle driven by the front axle, the rear axle is just a follower axle, which only plays a bearing role. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the bearing role, it also acts as a drive and deceleration. There is also a differential function. If it is four-wheel drive, there is generally a transfer case in front of the rear axle. The rear axle is divided into an integral axle and a ...

AI Technical Summary

Problems solved by technology

[0003] The rear axle housing of an automobile is generally made of polymer materials, and it usually needs to be punched during production. During the punching process, it is generally fixed by a clamping device in the prior art, resulting in Before and after processing, the clamping and loosening operations of the clamping device are required, which makes the operation more troublesome and affects the efficiency of processing. At the same time, when punching, the punching position needs to be set to facilitate the passage of the punching rod. In the suspended state, during the processing process, the plate at the punching position cannot be reliably supported, and it is prone to deformation and cracking
