According to incomplete statistics, machinery processing industry every year in die consumption value is five times the total value of all kinds of machine tools, it is conceivable that machinery, metallurgy, light industry, electronics, and other industries in the mold market is so huge. Another example: in the metallurgical industry, the annual hot rolling mill roll consumption is more than three hundred thousand tons, the value of hot rolled steel production costs accounted for more than 5%. Mold a large number of consumption, not only directly increase production costs, but also because of frequent replacement of the mold and a large number of production lines frequently stop production caused by greater economic losses.
Die failure in fact because of the local surface material wear and other reasons scrapped, and mold processing cycle is very long, processing cost is high (especially sophisticated molds or large mold manufacturing processing fee of up to hundreds of thousands of dollars or even hundreds of millions of dollars). Therefore, it is an important economic significance to enhance the service life of the die and mold by using the specific parts of the mold truly bearing wear. Large metal because, in addition to most of the mold surface is a thin layer of material is worn after the discard, so, only to die and key parts of abrasion on the surface of local repair, and in the repair process in the mold surface the real actual bearing wear surface coated with a layer of high hardness wear-resistant metal layer, "turning waste into treasure, not only make the mold repair, repair the mold service life will be compared with the original mould large increase, the economic benefits are enormous (for example: fix a root power motor shaft includes all kinds of preparation time, micro beam cold welding machine only takes a few days, but can create millions of yuan of economic benefits.
Die repairing machine is a high and new equipment to repair the surface of the die. Principle of mold repair machine is using high-frequency electric spark discharge principle, heat welding for the workpiece, to repair the defect on the surface of metal mold and wear, the main characteristics is small heat affected zone, mold repair can not deform after, annealing, no stress concentration and crack does not occur, to ensure the integrity of the mold; also can use it and strengthen the function of the die workpiece surface
strengthening treatment, mould wear resistance, heat resistance, corrosion resistance and.
The die repairing machine has long service life and good economic benefit. Can be applied to all kinds of iron base alloy (Tan Gang, alloy steel, cast iron), nickel base alloy and
other metal materials and parts of the mold and the surface strengthening and repair and a substantial increase in the use of life.
Scope of application: machinery, automobile, light industry, household electrical appliances, petroleum, chemical industry, electric power and other industrial equipment manufacturing departments and departments, aero engine wear and hot extrusion mould, warm extrusion film, touch the hot forging, rolling rolling guide, roll, automobile engine camshaft etc. parts and mold
