A multi-station steel strip laser welding system

Abstract

The invention discloses a laser welding system of multistation steel bands. The laser welding system comprises a laser welding mechanism and four workpiece clamping mechanisms, wherein the four workpiece clamping mechanisms are symmetrically arranged around the laser welding mechanism in pairs; the laser welding mechanism comprises a laser assembly and a regulating assembly, the laser assembly comprises a laser head and a fixed connecting piece, the laser head is fixed to the regulating assembly by virtue of the fixed connecting piece, the laser head is driven to lift and rotate all around by the regulating assembly, and the regulating assembly comprises a base, a plurality of support columns, an intermediate plate, a top plate, a guide piece, a lifting regulating piece and a rotation regulating piece. The laser welding system has the beneficial effects that the regulating assembly is arranged, so that the position of the laser assembly can be conveniently regulated so as to focus; four collision blocks are arranged on a rotary disk, and a travel switch is arranged on the top plate, so that the rotary disk can be accurately rotated and positioned, and a welding head on the rotary disk is suitable for welding the multistation steel bands.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a multi-station steel strip laser welding system. Background technique [0002] When coiling the tube, the steel strip is loaded at the front end in the form of a coil, and then transported on the conveyor belt after unwinding, and enters the tube coiling process of the production line through the processes of unwinding, head cutting, etc. When a coil of steel strip is used up, It is necessary to butt the head of the next roll of steel strip with the tail of the previous roll of steel strip, and then weld them together so that the production raw materials can be continuously and normally transmitted on the transmission line to ensure the normal production. The welding method currently used is Manual welding, this method has the following disadvantages: first, the labor cost is high, and professional technical workers are required to watch the operation; second, when the fro...

Problems solved by technology

[0002] When coiling the tube, the steel strip is loaded at the front end in the form of a coil, and then transported on the conveyor belt after unwinding, and enters the tube coiling process of the production line through the processes of unwinding, head cutting, etc. When a coil of steel strip is used up, It is necessary to butt the head of the next roll of steel strip with the tail of the previous roll of steel strip, and then weld them together so that the production raw materials can be continuously and normally transmitted on the transmission line to ensure the normal production. The welding method currently used is Manual welding, this method has the following disadvantages: first, the labor cost is high, and professional technical workers are required to watch the operation; second, when the front and rear two coils of steel belt are butted, sometimes the two sides are not aligned, which affects the subsequent coiled tube The third is that the welding quality is greatly affected by manpower, and sometimes there will be disconnections at the welding place during the transmission process, which affects the start-up rate of the entire production; the fourth is that each work needs to wait for the previous product to complete the laser process. Only then can the next feeding be carried out, and the efficiency is low. In the steel strip coiling tube, a multi-station steel strip laser welding system with stable quality and low cost is needed
