Surface laser cladding method of hydraulic support post and jack

Abstract

The invention relates to a surface laser cladding method of a hydraulic support post and a jack, which is characterized by comprising the following technology steps: 1, processing the surfaces of the post and the jack which are to be cladded; 2, feeding mixed gas (argon, nitrogen and carbon dioxide) to a laser generator; 3, electrifying the laser generator; 4, generating laser beam from the laser generator; 5,reflecting the laser beam by three mirrors; 6, feeding powder through a powder feeding machine; 7, focusing with a focus lens; 8, cladding metal powder on the surfaces of the post and the jack; 9, processing the surfaces of the post and the jack; and 10, obtaining the finished product. The invention has the advantages that the method has low dilution rate and small heat affected zone; the distortion of the cladding piece is smaller after forming metallurgy combination with a cardinal plane, and an automatic cladding process is easy to be achieved; and the method can greatly improve wear-resistant, corrosion-resistant, heat-resistant and antioxidant properties of base material surface, thereby meeting the requirements of the specific properties of the base material surface and saving abundant valuable elements as well as reducing pollution on environment.

Description

technical field [0001] The invention relates to a laser cladding method on the surface of a base material, in particular to a laser cladding method on the surface of a hydraulic support column and a jack. Background technique [0002] With the continuous expansion of coal mine production, the demand for hydraulic support for mine support is also increasing, and the surface treatment of the important components of the hydraulic support, the column and the jack, has been chrome-plated for decades. . The disadvantages of the electroplating process are: 1) Most electroplating equipment has serious environmental pollution and great social harm; 2) This process is a special process, which requires high thickness and porosity of the coating; 3) The electroplating layer is easy to fall off, causing The performance of the pillar is invalid, and the anti-corrosion effect is not ideal. Therefore, applying the existing electroplating process to treat the surface of the substrate can n...

Problems solved by technology

The disadvantages of the electroplating process are: 1) Most electroplating equipment has serious environmental pollution and great social harm; 2) This process is a special process, which requires high thickness and porosity of the coating; 3) The electroplating layer is easy to fall off, causing The performance of the pillar is invalid, and the anti-corrosion effect is not ideal

Therefore, the application of the existing electroplating process to treat the surface of the base part can no longer meet the higher requirements of corrosion resistance and wear resistance.
