Protection device for laser welding metal

Abstract

The invention discloses a protection device for laser welding metal. The protection device comprises a workbench, wherein the left side of the workbench is connected with a first protective cover through a first stepping motor, and the right side of the workbench is connected with a second protective cover through a second stepping motor; a first sliding groove and a second sliding groove are formed in the two sides of the workbench, wherein the first sliding groove and the second sliding groove are movably connected with a first sliding block and a second sliding block at the bottom of the first protective cover and the bottom of a second protective cover; the first protective cover and the second protective cover comprise frames, wherein grids are welded to the inner side and the outer side of each frame, and tempered glass plates are fixedly installed in the grids on the two sides; and dark acrylic plates are mounted between the tempered glass plates. According to the protection device for the laser welding metal, the protective covers can be moved, opened and closed through the stepping motors, so that a welding piece is convenient to operate and place; furthermore, an electriccylinder drives a laser welding structure, so that height adjustment is achieved, and energy consumption is reduced; and meanwhile, the tempered glass plates and the dark acrylic plates are arrangedon the protective covers so as to achieve isolation on laser radiation and strong lights.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to a protective device for laser welding metal. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts. [0003] However, in the prio...
