Strip steel plate type control system for butt welding

Abstract

The invention discloses a strip steel plate type control system for butt welding. The strip steel plate type control system determines a plate type deviation fluctuation condition by detecting a to-be-welded strip steel plate type; then, a multi-roller plate type flattening device is used to perform multi-time repeated bending, and targeted corrective flattening is performed to eliminate influences of plate type defects; a hydraulically driven pre-leveling part is used to further stabilize the plate type for pre-welded strip steel, and defects such as welding slag and bumps on the surface of awelding seam are eliminated by a strip steel welding seam and heat affected zone surface grinding part after welding; and a large-pressure strengthening leveling part is used for performing strengthening and optimizing on a welded welding seam area plate type. Through trial-operation verification, the quality defect problems such as height difference and gas holes of a welding seam as the strip steel plate type cannot be effectively flattened if ideal conditions such as waves, tilting and sinking appear while an original laser butt welding machine welds strip steel with poor plate type, namely the strip steel plate can be effectively solved, so that defects of the prior art are overcome, and therefore, the strip steel plate type control system is worthy of being greatly applied and popularized.

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...

AI Technical Summary

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
