Recently, with the support of Shaanxi Coal Group Tongchuan Mining, Xinsheng Coal Machinery Manufacturing Co., Ltd. invested more than 17 million yuan to build a laser pointer cladding production line, which was officially produced after the cladding, and the old hydraulic pillars were delivered to users, marking The company's technological innovation has once again reached a new level.
Xinsheng Coal Machine Manufacturing Co., Ltd. is a professional repairing manufacturer of hydraulic supports. The person in charge of the company is keeping a close eye on the frontiers of science and technology, fully researching and introducing external links. It actively contacts with the professional manufacturers of Xi'an Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences and decides to apply the laser pointer. Cladding carries out technological transformation and upgrading, breaking the bottleneck that affects the long-term development of enterprises.
The laser cladding technology is suitable for surface strengthening treatment of easily worn and corrodible parts. The metal coating material is placed on the surface of the substrate to be coated, and then irradiated with a thin layer on the surface of the substrate by laser irradiation. And rapidly solidified to form a surface coating with a very low dilution and metallurgical bonding with the substrate, thereby achieving a process for significantly improving the corrosion resistance, wear resistance, high temperature resistance, oxidation resistance and partial electrical characteristics of the surface of the substrate.
Under the rapid scanning of the high-energy laser pointer beam, the surface of the hydraulic cylinder of the ordered rotating cylinder is instantaneously micro-melted, and the alloy powder that is automatically synchronously fed is wound around the outer circumference of the column, and the surface of the column is superimposed and laminated. The cover is covered with a layer of "copper iron armor" that is densely bonded to the base metallurgy, which extends the service life of mechanical equipment such as hydraulic columns by 3 to 5 times.
At present, Xinsheng Coal Machinery Manufacturing Co., Ltd.'s laser cladding production line equipment runs smoothly. This technology can replace the electroplating process, help the enterprise green manufacturing technology innovation, and meet the environmental protection policy of green mining. The annual output value is expected to reach 40 million yuan.
