Automatic butt welding equipment for metal sheet

Abstract

The invention provides automatic butt welding equipment for metal sheet. The equipment comprises a frame, a welding machine, a welding gun, a welding gun operation driving mechanism, a laser director, an electric cabinet, a workpiece centering mechanism and a workpiece clamping mechanism, wherein the workpiece centering mechanism comprises a pad, a center positioning component, a left press plate component and a right press plate component; the workpiece clamping mechanism comprises two groups of clamp devices which correspond to the left press plate component and the right press plate component respectively; and each group of the clamp device at least comprises a fixed press plate pivot, and a pair of an extending air bag and a pressing air bag, and the pair of the extending air bag and the pressing air bag are positioned above the press plates and on the left side and the right side of the press plate pivot respectively. Furthermore, the left press plate and the right press plate respectively comprise a plurality of small press plates which are arranged in parallel, wherein the press plate in the middle is thickest, and the thicknesses of the small press plates are reduced progressively from the middle to two sides. Through the centering mechanism and the clamping mechanism, two metal sheets to be subjected to butt welding can easily realize centering and aligning of the workpiece, so that the butt welding can be automatically completed quickly and effectively, and the optimum butt welding quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to an automatic butt welding equipment for thin metal plates. Background technique [0002] Butt welding of sheet metal is a processing form often encountered in metal processing. But as we all know, the thinner the metal sheet, the more difficult it is to weld, especially when the thickness is less than 0.3mm, the welding difficulty of the metal sheet will increase greatly; when the thickness reaches 0.1mm, it is almost impossible to weld with conventional methods. If there is no special special equipment for sheet metal welding, whether it is argon tungsten arc welding, micro-beam plasma welding, or laser welding, the quality of butt welding of metal sheets cannot be guaranteed. In some existing welding professional technical materials or application manuals, although a series of references are also provided for the process parameters of thin plate welding, these proces...

But as we all know, the thinner the metal sheet, the more difficult it is to weld, especially when the thickness is less than 0.3mm, the welding difficulty of the metal sheet will increase greatly; when the thickness reaches 0.1mm, it is almost impossible to weld with conventional methods

If there is no special equipment for sheet metal welding, no matter whether it is argon tungsten arc welding, micro-beam plasma welding, or laser welding, the quality of butt welding of metal sheets cannot be guaranteed.

In some existing welding professional technical materials or application manuals, although a series of references are also provided for the process parameters of thin plate welding, these process parameters are either defective or cannot be applied in many cases
