Material clearing device for cylinder machining of vehicle body connection support

Abstract

The invention discloses a material clearing device for cylinder machining of a vehicle body connection support. The device comprises a punching machine hydraulic cylinder, a hydraulic cylinder oil way electromagnetic valve, a punching machine installing lower base plate, a waste material clearing cushion plate arranged on the punching machine installing lower base plate, a proximity switch arranged on the waste material clearing cushion plate, and a waste material clearing cylinder arranged on the waste material clearing cushion plate; a cylinder barrel of the waste material clearing cylinder is fixedly arranged relative to the position of the punching machine installing lower base plate; a waste material clearing push plate is arranged at the free end of a piston rod of the waste material clearing cylinder; and the proximity switch is located below the resetting position of the waste material clearing push plate, and is connected with and controls the hydraulic cylinder oil way electromagnetic valve. The material clearing device is not prone to the stuck fault, the friction force is small during machining waste material clearing operation, the energy consumption is low, and abrasion of long-time operation to an installing base of a material pushing plate and a punching machine is small.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a material cleaning device for a machined cylinder of a vehicle body connection bracket. Background technique [0002] The body connection bracket is an important support component used to install and fix various functional component assemblies such as steering support. The quality of its processing directly affects the installation positioning accuracy of various functional component assemblies and the reliability of the connection. There are many types of body connecting brackets with large structural differences, and in order to have high connection reliability, high mechanical strength and certain rigidity are required, so the body connecting brackets usually have relatively large volume and mass. [0003] During the mechanical processing of the body connection bracket, after the raw material steel plate or the blanking steel plate passes through the p...

AI Technical Summary

Problems solved by technology

[0003] During the mechanical processing of the body connection bracket, after the raw material steel plate or the blanking steel plate passes through the punching machine and the punching die of the stamping die, the corner waste will fall from the blanking through hole of the lower die of the stamping die and accumulate on the punching machine. On the installation base of the stamping machine, it is necessary to regularly clean up the corner waste accumulated on the installation base of the punching machine. Excessive accumulation of corner waste will affect the subsequent waste accumulation, and even easily cause the corner waste to be ejected under force, thus threatening the safety of the operator. Personal safety; the conventional machining waste cleaning device is to drive the pusher plate to move through the cylinder to clean up the machining waste between the mounting base of the stamping machine and the bottom of the lower die of the stamping die. The problem with the above operation method is that the pushing During the working process, the material plate itself will form steric resistance or force on the falling waste, making the machining waste easy to be ejected by the action of the pushing plate; in addition, if the pushing plate is too closely in contact with the mounting base of the punching machine, If the friction force is too large, not only will the energy consumption be high during operation, but also the wear and tear on the pusher plate and the mounting base of the punching machine will be greater after long-term operation; if there is a gap between the pusher plate and the mounting base of the punching machine, the gap is easy Plug edge and corner waste, resulting in jamming failure of machining waste cleaning device
