Problems solved by technology

However, it is necessary to use a high-power continuous fiber laser (such as the IPG-2000W fiber laser mentioned in the patent application specification), which leads to high construction costs of the device (the cost of the high-power fiber laser itself is very high, and it also requires cooling and subsequent optical path systems. It is harsh, so the system construction cost is high); the powder spreading system with two powder cylinders and one powder spreading roller needs at least four motors to work in coordination, which is not conducive to improving cladding efficiency

Abstract

The invention relates to a quick laser cladding device of flat metal parts. The quick laser cladding device comprises five modules, namely an electrostatic powder spraying device, a quick laser galvanometer scanning device, a gas protection module, a parts conveying module, and a parts fixing clamp. The quick laser cladding device has the advantages of low equipment building and operating costs, fast powder adding method, fast cladding speed, good cladding layer surface quality, accurate and controllable cladding layer thickness and the like. According to the quick laser cladding device, the system building and operating costs are reduced, the production efficiency is improved, and good cladding quality is also obtained. By adopting the method, the requirements of cladding the flat metal parts at low cost, large batch, high speed and high quality can be met.

Description

technical field [0001] The invention belongs to the technical field of laser surface modification, and relates to a laser rapid cladding device and a cladding method for planar metal parts. Background technique [0002] Laser cladding is a laser surface modification technology that uses high-energy-density laser beams to clad powder materials on the surface of parts to obtain coatings with excellent mechanical properties. The liquid alloy formed after the powder is melted by the laser beam is rapidly solidified and crystallized due to the rapid heat conduction of the matrix material, which not only produces a firm and good metallurgical bond, but also obtains a fine and uniform microstructure (that is, the coating Excellent microstructure), so a surface coating with excellent mechanical properties, wear resistance and corrosion resistance can be obtained. [0003] Compared with the traditional heat treatment technology, the laser cladding technology has the following main a...
