Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal heat treatment equipment, and in particular to a high-frequency air-cooled induction heating device. Background Technology
[0002] Air-cooled induction heating equipment is a highly efficient, energy-saving, and safe fire-fighting device widely used in industrial fields. This equipment utilizes the principle of electromagnetic induction, generating a high-frequency electromagnetic field through a built-in electromagnetic coil. When metal materials such as steel and aluminum enter the electromagnetic field range, the molecules inside the material begin to move rapidly and rub against each other, thereby generating heat and achieving the purpose of rapid heating.
[0003] Existing high-frequency air-cooled induction heating equipment, such as the high-frequency air-cooled induction heating equipment disclosed in utility model patent application number 202322559752.9, mainly includes an equipment box with an induction coil on the equipment box, a support base located on one side of the equipment box, a cavity on the support base, and a placement plate located in the cavity. In use, when the two sets of pressure seats are pressed together under the action of the elastic element, the two sets of inclined surfaces form an opening with an inverted triangular cross section. Since the shapes and sizes of the workpieces are different, it is convenient to move the workpieces that are placed horizontally, and the workpieces can be placed between the two sets of inclined surfaces.
[0004] However, most existing induction heating equipment is open-type, and workers can easily get burned if they accidentally touch it. Moreover, traditional high-frequency induction heating equipment generally uses a water cooling system to cool the induction coil and power devices, which requires high water quality and is prone to scaling and clogging of pipes, resulting in frequent maintenance. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-frequency air-cooled induction heating device that not only uses air cooling to cool the induction coil and power devices, avoiding scale buildup and pipe blockage in the water circuit, thus saving the trouble of subsequent maintenance, and utilizing waste heat, but also protects the induction coil to prevent burns to workers.
[0006] This utility model discloses a high-frequency air-cooled induction heating device, including a heating mechanism; it also includes a storage mechanism, a moving mechanism, a clamping mechanism, and an air-cooling mechanism.

The positioning grooves of the second protective box and the first protective box cooperate to prevent workers' palms from being inserted and causing burns.
[0010] Preferably, the clamping mechanism includes a bracket, a stepper motor, a rotating shaft, a hydraulic cylinder, and grippers.
