Optimized shearing control system for side of thick plate

Abstract

The invention discloses an optimized shearing control system for the side of a thick plate. Coordinate data, detected by a planar detection device, is of the edge contour of the rolled large plate isadopted as a basis, L2 conducts calculation comparison according to original planning data and own set data sent by L3, and according to the comparison result, a double-side trimming shear is controlled to conduct or not conduct shearing. The problem is effectively solved that in the prior art, an operator has to conduct shearing on light plates and carefully confirm that the actual edge shearingamount of on-site steel plates meets requirements, and then whether or not current steel plates can be normally sheared is determined manually, so that unreliability is generated; through computers, automatic auxiliary calculation is conducted, a shearing strategy is made, the operator only needs to execute operation according to the shearing strategy, in this way, a good solution is provided forautomatic and intelligent shearing of the thick plate, meanwhile, labor intensity is lowered, the good effect on promotion of shearing reliability and production efficiency is realized, and the effectis durable and reliable.

Description

technical field [0001] The invention relates to thick plate automatic shearing equipment, in particular to a thick plate edge optimal shearing control system. Background technique [0002] The double-sided shear is located after the cutting head shear and before the fixed-to-length shear. It is used to cut the edges on both sides of the thick plate. Therefore, whether the shearing efficiency of double-sided shears is high and whether the trimming quality is good and stable will directly affect the logistics rhythm of the entire shearing line and the quality of the final product, which is of great importance. [0003] There are two most basic and very strict limit requirements for the trimming amount of the steel plate to be sheared by double shear: (1) The actual minimum trimming amount of the steel plate to be sheared must be greater than or equal to the minimum value allowed by the equipment. The purpose of this is to To ensure that the cut waste edge can be continuously ...

AI Technical Summary

Problems solved by technology

This traditional operation method has obvious disadvantages: Whether the double-sided shearing of the steel plate can be trimmed or not depends entirely on the manual judgment of the operator, which has great unreliability and high labor intensity, and is not conducive to equipment maintenance and the quality of the steel plate after shearing Quality Control

Although this method of operation can assist the operator to quantitatively determine the amount of trimming on one side through the backing, the disadvantages are also very obvious: (1) If the shape of the edge of the incoming steel plate is not good, especially when the steel plate has a camber, The backing located at the head and tail of the steel plate basically does not play its due role, and cannot assist in measuring the trimming amount within the entire length of the steel plate; (2) Even if the incoming steel plate is in good shape, if the actual trimming amount is large, this This operation method will cause the problem that the trimming amount on one side only meets the minimum requirement for normal cutting, while the remaining trimming amount on the other side is too large

It does not meet the shearing requirement that the amount of edge trimming on both sides should be kept as uniform as possible during bilateral shearing, which is not conducive to the quality control of the edge of the steel plate after shearing
