An equipment and control method for shearing length of aluminum alloy medium-thick plate

Abstract

The invention provides an aluminum alloy medium-thick plate shear length sizing device and a control method, which belong to the technical field of non-ferrous technology processing. The equipment includes a hydraulic lifting device and a laser range finder. The laser range finder is installed on the lifting platform at the top of the hydraulic lifting device, and the hydraulic lifting device can be lifted vertically. The main principle of using this equipment to cut aluminum plate to length is to measure the position of the head of the aluminum plate with a laser range finder, and then calculate the distance between the head of the aluminum plate and the cut-to-length shear, so as to accurately control the shearing length of the aluminum plate . The invention can accurately control the shearing length of the aluminum plate to meet the user's requirements for stepless sizing, the length control accuracy is within an ideal tolerance range, the design structure is simple, the sizing accuracy is stable and reliable, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of shearing length and sizing equipment and control methods for aluminum alloy medium and thick plates, in particular to an aluminum alloy medium and thick plate shearing length and sizing equipment and control method. Background technique [0002] The main application fields of aluminum alloy plate are transportation, tool and mold manufacturing and machinery manufacturing, among which the transportation industry is mainly used in aerospace industry, shipbuilding and automobile manufacturing. With the fierce competition in the market, users have higher and higher requirements for product surface quality and product dimensional accuracy. Aluminum alloy manufacturers are also facing pressure to reduce costs and increase product quality. The requirements for the length accuracy of aluminum alloy medium and thick plates Also getting higher and higher. At present, the sizing methods of the aluminum alloy medium...

Problems solved by technology

Due to the bright and reflective surface of the aluminum alloy, the slow transportation speed of the aluminum plate on the roller table and other factors have a certain impact on the measurement accuracy of the laser speedometer, and the purchase cost of the laser speedometer in the early stage and the maintenance cost in the later stage are relatively high.

The speed measuring method of installing a rotary encoder on the operating side of the roller table indirectly measures the speed of the aluminum plate through the speed of the roller table. The advantage is that the initial investment is small, the later maintenance is simple, and the disadvantage is that the measurement accuracy is poor
