According to incomplete statistics, the annual consumption value of molds in the machining industry is five times the total value of various machine tools. It is conceivable that the mold market in machinery, metallurgy, light industry, electronics and other industries is so huge. Another example: in the metallurgical industry, the annual consumption of hot-rolled rolls alone is more than 300,000 tons, and the value of hot-rolled rolls accounts for more than 5% of Auto air conditioner snail shell mold Plant the cost of steel production. The large consumption of molds not only directly increases production costs, but also causes greater economic losses due to frequent shutdown of a large number of production lines due to frequent mold replacement.
The failure of the mold is actually scrapped due to the local material wear on the surface layer, and the processing cycle of the mold is very long and the processing cost is extremely high (especially the manufacturing and processing cost of precision and complex molds or large molds is as high as hundreds of thousands of yuan or even millions of dollars. Yuan). Therefore, it is undoubtedly a method with important economic significance to strengthen the surface of the specific parts of the mold that are really subjected to wear, so as to greatly extend and improve the service life of the mold. In addition, most molds fail and are scrapped only because a thin layer of material is worn on Auto Air Conditioner Bracket Mould Plant the surface. Therefore, it is only necessary to repair the worn local areas on the surface of the mold and key metal parts, and in the repair process, the surface of the mold is actually subjected to wear and tear. The surface of the mold is coated with a high-hardness and high-wear-resistant metal layer, which can "turn waste into treasure", not only the mold can be repaired, but the service life of the repaired mold will be greatly improved compared with the original mold, and the economic benefits will be huge (such as : It only takes a few days to repair a large shaft of a power plant motor including various preparation times, but it can create economic benefits of millions of yuan).
Mold repairing machine is a high-tech equipment for repairing mold surface wear and processing defects. The principle of the mold repairing machine is to use the principle of high-frequency electric spark discharge to perform heat-free surfacing welding on the workpiece to repair the surface defects and wear of the metal mold. The main feature is that the heat-affected area is small, and the mold will not be deformed, annealed, There is no stress concentration and no cracks, which ensures the integrity of the mold; it can also use its strengthening function to strengthen the surface of the mold workpiece to achieve wear resistance, heat resistance, and corrosion resistance of the mold.
The mold repairing machine strengthens the mold with long service life and good economic benefits. It can be used to strengthen and repair the surface of various iron-based alloys (carbon steel, alloy steel, cast iron), nickel-based alloys and other metal materials, molds and workpieces, and greatly improve the service life.
Scope of application: machinery, automobile, light industry, household appliances, petroleum, chemical industry, electric power and other industrial equipment manufacturing departments and use departments, key wear parts of aero-engine, hot extrusion dies, warm extrusion film tools, hot forging dies, rolling steel rolling Parts and molds for guides, rollers, camshafts of automobile engines, etc.
