Problems solved by technology
[0003] The purpose of the present invention is to provide a butt welding strip shape control system to solve the unsatisfactory situation that the original laser butt welding machine welds the strip with poor shape, that is, the strip shape has waves, warps, and undercuts. When it is used, the steel plate type cannot be effectively leveled, resulting in quality defects such as height difference and pores in the weld

Abstract
The invention discloses a butt-welded strip steel shape control system, through which the strip steel shape to be welded is detected, the shape deviation fluctuation is determined, and then the multi-roller shape leveling device is controlled to use multiple times of repeated bending to perform Targeted correction and leveling to eliminate the influence of plate shape defects. At the same time, hydraulically driven pre-leveling components are used to further stabilize the plate shape before welding. slag, bulge and other defects, and finally use high-pressure strengthening flat parts to strengthen and optimize the plate shape of the weld area after welding. Through the trial operation verification, it can effectively solve the problem that the original laser butt welding machine cannot effectively straighten the strip steel plate when welding the strip steel with poor plate shape, that is, the strip steel plate shape has unsatisfactory conditions such as waves, warping, and undercutting, which leads to welding Seam height difference, air holes and other quality defects, overcome the deficiencies of the existing technology, it is worthy of vigorous promotion and application.
Description
technical field [0001] The present invention relates to butt welding equipment, more specifically, relates to a butt welding strip steel profile control system. Background technique [0002] The cold-rolled acid tandem mill adopts a laser butt welding machine, which welds a large number of high-strength and ultra-high-strength steel strips. The ultra-high-strength steel is hard and tough. In an ideal situation, there will be weld seam quality defects such as height difference and air holes during butt welding. Although the welding machine is equipped with a pre-leveling wheel device with disc springs, it cannot effectively correct the plate shape. In order to be able to weld and produce, only Cut off the head and tail of the strip with bad shape, resulting in a lot of waste. When the bad shape of the strip cannot be eliminated by multiple cuts, the weld with defects can only be released, resulting in such welds being too continuous Strip breakage easily occurs during the ro...
