High molecular plate punching device for automobile rear axle housing production

Abstract

The invention discloses a high molecular plate punching device for automobile rear axle housing production. The high molecular plate punching device comprises a base and a punching air cylinder, a containing groove is formed in the base, a liquid storage groove is formed in the center of the containing groove, the liquid storage groove is sealed through an elastic film, a conductive plate is fixedly connected to the bottom of the liquid storage groove, a conductive net is arranged in the elastic film, and a mounting barrel is fixedly connected to the punching air cylinder; the bottom of the mounting barrel is fixedly connected with a punching rod, and the outer wall of the mounting barrel is fixedly connected with an electrostatic generator; the conductive plate and the conductive net are powered on to enable electrorheological fluid to be hardened to support a plate, and the punching air cylinder drives the punching rod to descend for punching; when the punching rod descends, negative charges gathered at the tip of the punching rod enable negative charges on the conductive net to be discharged, therefore, the electrorheological fluid at the punching position is softened, and punching operation is facilitated; and meanwhile, the electrorheological fluid on the periphery of the punched position is in a hardened state, the plate is supported, and deformation of the punched position is avoided.

Description

technical field [0001] The invention relates to the technical field of processing devices for automobile parts, in particular to a punching device for polymer plates used in the production of rear axle housings of automobiles. Background technique [0002] The rear axle of a car refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-bridges that can implement half-bridge differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels. If it is For vehicles driven by the front axle, the rear axle is just a follower axle, which only plays the role of load bearing. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to carrying the load, it also plays a role in driving and deceleration. There is also the role of differential speed. If it is four-wheel drive, it is generally equipped with a transfer case in front of the rear axle. Th...

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
