Problems solved by technology

However, chrome plating has a long production cycle, unstable quality and other factors that restrict product quality. The waste water and waste gas produced by chrome plating are relatively serious environmental pollution. Environmental protection issues have attracted much attention and attention in today's society. The concept of sustainable development of green environmental protection is also implemented. in all walks of life

Abstract

The invention discloses a manufacturing process for a wear-resistant and corrosion-resistant central water pipe of a rocker arm of a coal shearer, comprising the following steps: 1. blanking; 2. straightening; 3. rough machining; 4. laser cladding; ; Sixth, the surface is smooth, and the central water pipe of the rocker arm of the coal mining machine is obtained. In the present invention, a laser cladding section and a non-laser cladding section are processed on the dynamic sealing section, and a laser cladding layer is prepared by laser cladding on the laser cladding section. While reducing the laser cladding area, it does not It affects the use of the central water pipe. By controlling the parameters of laser cladding, the efficiency of laser cladding is improved, the surface of the cladding layer is smooth, the precision control is high, and the cladding layer is full. Laser cladding replaces the traditional chrome plating process. , improves the wear resistance and corrosion resistance of the dynamic sealing section, ensures that the dynamic sealing section can also play an excellent sealing role during relative movement, has a higher sealing effect, and can still seal stably when the central water pipe moves.
