What are the main uses of high-frequency machines?

The practical applications of high-frequency machines include heating, heat treatment, welding, and annealing. Working principle: The high-frequency high current of the high-frequency machine flows towards a heating coil that is wound into a ring or other shape (usually made with a copper tube high-frequency machine). As a result, a strong magnetic beam with instantaneous polarity changes is generated within the coil. When metal or other heated objects are placed inside the coil, the magnetic beam will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a corresponding eddy current will be generated. Due to the presence of resistance within the heated object, a significant amount of Joule heat is generated, causing the object's own temperature to rapidly rise. To achieve the purpose of heating all metal materials.

The following are high-frequency machines - practical applications:

1： Heating 1. Hot forging mainly involves heating the workpiece to a certain temperature (the heating temperature varies depending on the material), and then forging the workpiece into other shapes through punching machines, forging machines, or other forms. For example, watch cases, watch blanks, handles, mold accessories, kitchen utensils, handicrafts, standard parts, fasteners, mechanical parts processing, copper locks, rivets, steel drills, hot extrusion of drilling tools, and so on. 2. Heat matching mainly refers to the connection between different types of metals or between metals and non-metals through the heating of metals, using the principle of thermal expansion or melting to connect the two together. For example, copper core and aluminum sheet of computer heat sink, buried value welding of horn mesh, composite of steel plastic pipes, sealing of aluminum foil (toothpaste), sealing of motor rotor, electric heating tube, etc. 3. Melting mainly refers to the process of converting metals into liquids through high temperature treatment. It is mainly suitable for iron, steel, copper, aluminum, zinc, and various precious metals. Like the melting of gold and silver.

2： Heat treatment mainly involves heating the workpiece and other treatments to change the hardness of the metal material. The specific applications are as follows: 1. Various hardware tools and hand tools. Quenching of pliers, wrenches, hammers, axes, screwdrivers, scissors (gardening scissors), etc; 2. Various car and motorcycle accessories. Quenching of crankshafts, connecting rods, piston pins, sprockets, aluminum wheels, valves, rocker shafts, transmission half shafts, small shafts, pulleys, etc; 3. Various electric tools. Such as gears and shafts; 4. Machine tool industry. Quenching of machine bed surfaces, machine guide rails, etc; 5. Various hardware and metal parts, mechanical processing parts. Quenching of shafts, gears (sprockets), camshafts, chucks, fixtures, etc; 6. Hardware mold industry. Quenching of small molds, mold accessories, mold inner holes, etc;

3： Welding is mainly achieved by heating the solder to a certain temperature to melt it, thereby connecting two metals of the same or different materials together. The specific applications are as follows: 1. Welding of various hardware cutting tools: diamond cutting tools, grinding tools, drilling tools, alloy saw blades, hard alloy turning tools, milling cutters, reamers, planers, woodworking drills, etc; 2. Welding of various hardware and mechanical accessories: silver welding and copper welding of the same or different metals, such as hardware bathroom products, refrigeration copper accessories, lighting accessories, precision mold accessories, hardware handles, egg beaters, alloy steel and steel, steel and copper, copper and copper, etc; 3. Composite pot bottom welding is mainly used for three-layer brazing of round, square, and other irregular flat stainless steel pot bottoms and aluminum sheets, and can also be used for brazing other metal flat surfaces. 4. The welding of the heating plate of an electric kettle (electric coffee pot) is mainly used for brazing between stainless steel flat bottoms, aluminum sheets, and various shapes of electric heating pipes. 5. The welding of communication products has stable welding quality and can be paired with automated equipment for welding.

4： Annealing 1. Annealing in various stainless steel industries. Such as annealing and stretching of stainless steel pots and cans, annealing of rolled edges, annealing of sinks, stainless steel pipes, stainless steel tableware, stainless steel cups, etc; 2. Annealing of various other metal workpieces. Such as golf balls, clubs, copper locks, hardware copper accessories, kitchen knife handles, blades, aluminum pots, aluminum buckets, aluminum radiators, and various aluminum products.
