According to incomplete statistics, the value of annual mold consumption 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 the production cost of steel. The large consumption of molds not only directly increases production costs, but also causes greater economic losses due to frequent shutdowns of a large number of production lines due to frequent mold replacement.
In fact, the failure of the mold is scrapped due to the wear of the local material on the surface, and the processing cycle of the mold is very long, and the processing cost is extremely high (especially the manufacturing and processing costs of precision and complex molds or large molds are as high as hundreds of thousands or even millions. yuan). Therefore, it is undoubtedly a method of great economic significance to strengthen the surface of the specific parts of the mold that really bear the effect of wear to greatly extend and increase the service life of the mold.
In addition, most molds fail and are scrapped only after a thin layer of material on the surface is worn. Therefore, it is only necessary to repair the worn parts of the surface of the mold and key metal parts, and the mold surface is actually subjected to wear during the repair process. Coating a layer of high hardness and high wear-resistant metal on the surface of the mold can “turn waste into treasure”. Not only will the mold be repaired, the service life of the repaired mold will also be greatly improved than the original mold, and the economic benefits are huge (such as : It only takes a few days to repair a large shaft of a power plant motor, including various preparation times, using a micro-beam cold welding machine, but it can create millions of economic benefits).
Mold repair machine is a high-tech equipment to repair mold surface wear and processing defects. The principle of the mold repair machine is to use the principle of high-frequency electric spark discharge to perform non-thermal surfacing 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 or annealed after repairing. There is no stress concentration, no cracks, and the integrity of the mold is guaranteed; its strengthening function can also be used to strengthen the surface of the mold workpiece to achieve the mold’s wear resistance, heat resistance, and corrosion resistance.
The mold repair machine strengthens the mold with long life and good economic benefits. It can be used to strengthen and repair the surface of various metal materials such as iron-based alloys (carbon steel, alloy steel, cast iron), nickel-based alloys, and other metal materials, and greatly increase the service life.
Applications: Machinery, automobiles, light industry, home appliances, petroleum, chemical, electric power and other industrial equipment manufacturing departments and use departments, key wear-resistant parts of aero engines, hot extrusion dies, warm extrusion film tools, hot forging dies, rolling steel rolling Parts and molds such as guide guards, rolls, automobile engine camshafts, etc.
