After heating a high-frequency machine practical purposes, it is mainly the metal forging the workpiece is heated to a certain temperature (heating temperature according to different materials or different) frequency heat sealing machine, through the press, forging bed or other forms of forging the workpiece into other shapes. For example: Case, Table embryo, handle, mold accessories, kitchen utensils supplies, crafts, standard parts, fasteners, machine parts, lock, rivets, drill rod, drill with the hot extrusion and so on. 2, heat tie between it mainly refers to different kinds of metal or metal-to-metal and nonmetal heating by high-frequency welding machines, using the principle of thermal expansion or thermal melting so that the two together. For example: computer radiator copper and aluminum, horn buried net value of welding, steel tube composite, aluminum foil sealing (toothpaste), motor rotor, electric pipe sealing and so on. 3, melting it mainly refers to the high temperature of the metal, the metal into liquid, mainly used in iron, steel, copper, aluminum, zinc and various precious metals. Such as gold, silver is melted. With the induced current local heating of the workpiece surface heat treatment process. This commonly used in surface hardening heat treatment process can also be used for local annealing or tempering, sometimes for a whole quenching and tempering. The early 1930s, the United States, the Soviet Union has began to use the method of induction heating surface hardening of parts. With industrial development, induction heating heat treatment technology continues to improve, the application scope has been expanded. ① do not have the advantages of heating the whole, small deformation of the workpiece, the power consumption is small. ② pollution. ③ heating speed, surface oxidation and decarbonization lighter. ④ surface hardened layer can be adjusted Qingdao welding machine according to need, and easy to control. ⑤ heating equipment can be installed in machining production line, easy to implement mechanization and automation, easy to manage high frequency heat sealing machine price, and can reduce transportation, saving manpower, improve production efficiency. ⑥ hardened layer of fine martensite, hardness, strength and toughness are higher. ⑦ After the surface has hardened workpiece surface compressive stress within the larger, higher workpiece fatigue breaking capacity.
