According to incomplete statistics, the annual consumption 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 rolling rolls alone is more than 300,000 tons, and the value of hot rolling rolls accounts for more than 5% of the steel production cost. The large consumption of molds not only directly increases production costs, but also causes frequent shutdowns of a large number of production lines due to frequent replacement of molds, resulting in greater economic losses.

In fact, the failure of the mold is scrapped due to the wear and tear 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 cost of precision and complex molds or large molds is as high as hundreds of thousands or even millions. Yuan). Therefore, it is undoubtedly a method of great economic significance to carry out surface strengthening on the specific part of the mold that is actually subjected to wear, so as to greatly extend and improve the service life of the tool and mold. In addition, most molds are invalid and scrapped after only a thin layer of material on the surface is worn away. 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. The surface of the mold is coated with a layer of 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 are huge (such as : It only takes a few days to repair a large shaft of a power plant motor including various preparation times with a micro-beam cold welding machine, 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 carry out athermal 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 after repairing. There is no stress concentration and no cracks, which ensures the integrity of the mold; it can also be used to strengthen the surface of the mold workpiece to achieve wear resistance, heat resistance, corrosion resistance, etc. of the mold.

The mold repairing machine strengthens the mold with long service life and good economic benefits. It can be applied to various iron-based alloys (carbon steel, alloy steel, cast iron), nickel-based alloys, etc., to strengthen and repair the surface of various metal molds and workpieces, and greatly increase the service life.

Application scope: Machinery, automobile, light industry, household appliances, petroleum, chemical industry, electric power and other industrial equipment manufacturing departments and user departments, key wear-resistant parts of aero-engines, hot extrusion dies, warm extrusion film tools, hot forging dies, steel rolling Guides, rollers, automotive engine camshafts and other parts and molds
