Metal plate longitudinal rolling shearing machine super-long scrap edge automatic reversing discharging device

Abstract

The invention provides a metal plate longitudinal rolling shearing machine super-long scrap edge automatic reversing discharging device. The initial position of a baffle in an automatic overturning discharging device is flush with a plate, an air cylinder telescopic rod conducts linear telescopic motion, the air cylinder telescopic rod stretches out and draws back once, the discharging device completes one-time reversing motion, and the cut super-long plate can fall into a discharging chute below after being reversed by a reversing device. According to the discharging chute device at the lowerend, an upper chute and a lower chute are connected, material transportation is facilitated, and automatic discharging is achieved through relevant angle setting. The phenomenon that cut scrap edgesdroop due to self gravity in the feeding process is effectively avoided, lifting of the scrap edges of the plate is achieved, meanwhile, limitation on the length of the cut scrap edges of the plate isgreatly reduced, shearing and reverse discharging of the scrap edges of the super-long plate are achieved, super-long material supporting, reverse discharging and material collecting devices are integrated, and the working efficiency is greatly improved while the product quality is improved.

Description

technical field [0001] The present invention relates to a kind of auxiliary equipment of longitudinal rolling shearing machine equipment, in particular to a kind of metal plate longitudinal rolling shearing machine super-long broken edge automatic reverse discharging device. Background technique [0002] Longitudinal rolling shearing machine is used for edge shearing of long steel plates. The feeding step method adopts pinch roller feeding, and the length is calculated by installing contact length measuring rollers or laser speed measuring before and after the tool holder. It is very difficult to synchronously control the feeding of the pinch roller with 4 motors (a total of 8 motors at the entrance and exit of the double-sided shears). Problems such as scale build-up and wear can affect cut-to-length accuracy and sheet squareness. [0003] At present, the method of high-speed small-step feeding is adopted, that is, when the scrap sheet reaches a certain length, it is cut o...

Problems solved by technology

However, the sheets cut by this method are generally shorter, so a higher cutting frequency is required, resulting in the frequent occurrence of the aforementioned problems, and the number of times the cut edges fall vertically on the belt causes frequent impacts and aggravates belt wear , shorten the service life of the belt
