A high frequency machine is a heating induction coil that is wound into a ring shape or a desired shape by a high current that emits a high frequency. The high frequency induction is usually made of a copper hollow tube. In the opposite direction of the induction heating current inside the induction heating object, a corresponding strong eddy current is generated. Because the inductively heated metal has electrical resistance, it generates strong Joule heat energy, which causes the temperature of the object to be heated to rise rapidly, thereby achieving the purpose of heat treatment. Therefore, Xinyu high-frequency induction heating machine in the industry, can also be called: high-frequency induction heating equipment; high-medium frequency induction quenching equipment; high-frequency heating machine.

Therefore, Xinyu high-frequency induction heating machine in the industry, can also be called: high-frequency induction heating equipment; high-medium frequency induction quenching equipment; high-frequency heating machine.
Equipment introduction
The high frequency machine is a general term for all high frequency equipment, one is to heat the metal material, and the other is to heat the non-metal material. It can be used in pure PVC or any soft and hard film containing 30% PVC or more, and can be processed for special purposes such as leather or cloth.
The high-frequency machine is the current induction heating device with the highest heating efficiency, the fastest speed, low energy consumption and environmental protection. High-frequency machine full name "high-frequency induction heating machine", also known as high-frequency heating machine, high-frequency induction heating equipment, high-frequency induction heating device, high-frequency heating power supply, high-frequency power supply, high-frequency welding machine, high-frequency induction heating machine, High-frequency induction heaters (welders), etc., as well as intermediate frequency induction heating equipment, ultra-high frequency induction heating equipment. The scope of application is very wide.
Structural principle
Sheet profiles of small length, as well as channel section parts, are traditionally manufactured in one or two stampings in a dedicated mold. It is also possible to stamp by unit with a universal tool, but the flat section 3 should be wide enough when using this method. When manufacturing the punch and die of a special mold, it should be entered from the nominal thickness of the material. Departure and work with the work surface. In the closed position, the mold should correct the flat section of the part and eliminate the effects of free bending of the blank. The actual value of the blank thickness may be entered. The values vary widely, so not all segments are being corrected.
For example, for high-precision sheet steel, the tolerance δ of thickness h0 = 2 mm is ± 0.15 mm. When a blank with a nominal thickness is used to correct a blank of h = 2.15 mm, the gap between the punch and the die on the two segments is 2.15 mm, and on the one and three segments, when σ = 30, Z = 2.3 mm. . If hh is on 2 segments. Uneven correction will be negatively reflected in the accuracy of the part, which is one of the shortcomings of the traditional process. The disadvantages of conventional processes are the high cost of the molds and equipment, as the peak load characteristics of the press produce too much power.
working principle
The high-frequency, high-current current of the high-frequency machine is wound into a heating coil (usually made of a copper tube) that is wound into a ring or other shape. Thereby, a strong magnetic flux whose polarity changes instantaneously is generated in the coil, and an object to be heated such as a metal is placed in the coil, and the magnetic flux penetrates the entire object to be heated, and is generated in the opposite direction to the heating current inside the object to be heated. Corresponding to a large eddy current. Since there is a resistance in the object to be heated, a lot of Joule heat is generated, and the temperature of the object itself rises rapidly. Achieve the purpose of heating all metal materials.
Application field
The application of the equipment is mainly caused by the heating of the workpiece and the like, so that the hardness of the metal material changes, the specific application is as follows:
1. Machine tool industry, such as machine bed surface, machine tool guide rails, etc.;
2. All kinds of hardware metal parts, machined parts. Quenching such as shafts, gears (sprocket wheels), cams, collets, clamps, etc.

6. Various power tools, such as gears and shafts;
1. Annealing in various stainless steel industries. Such as stainless steel pots, cans of annealing, annealing and annealing of the water tank, stainless steel tubes, stainless steel cutlery, stainless steel cups, etc.;
2. Annealing of various other metal workpieces. Such as golf clubs, clubs, copper locks, hardware copper fittings, kitchen knife handles, cutting edges, aluminum pots, aluminum barrels, aluminum radiators and all kinds of aluminum products.
Equipment Application 1. Thermal fit It mainly refers to the heating of the metal between different kinds of metals or between metal and non-metal, and the two are connected by the principle of thermal expansion or thermal melting. For example: the copper core of the computer radiator and the aluminum sheet, the buried value welding of the speaker net, the composite of the steel-plastic tube, the sealing of the aluminum foil (toothpaste skin), the rotor of the motor, the sealing of the electric heating tube and the like.
2. Melting it mainly refers to the metal into a liquid by the high temperature of the metal, mainly suitable for iron, steel, copper, aluminum, zinc and various precious metals. Such as the melting of gold and silver.
3. Hot forging is mainly after heating the workpiece to a certain temperature (the heating temperature is different depending on the material)
The high frequency machine forges the workpiece into other shapes by punching, forging or other forms. For example: case, watch embryo, handle, mold attachment, kitchen tableware, crafts, standard parts, fasteners, machining of mechanical parts, copper locks, rivets, steel brazing, hot extrusion of brazing tools, etc.
It mainly connects the two materials of the same material or different materials by heating to a certain temperature to melt the solder. The specific application is as follows:
1. Composite pot bottom welding is mainly used for three-layer brazing of round, square and other special-shaped flat stainless steel pot bottoms and aluminum sheets, and can also be used for other metal plane brazing.
2. The electric heating plate of the electric kettle (electric coffee pot) is mainly used for brazing between stainless steel flat bottom, aluminum sheet and electric heating tubes of various shapes.
