Medium-frequency heating equipment

Abstract

The invention discloses medium-frequency heating equipment. The medium-frequency heating equipment comprises a heating device and a supporting table. The heating device comprises a heating turntable and a heating channel; the heating turntable comprises a turntable motor and a turntable body; the output end of the turntable motor is arranged downwards and provided with a turntable rotating shaft through a coupler, wherein the axial direction of the turntable rotating shaft is perpendicular to a supporting table top; the turntable rotating shaft penetrates into the supporting table and is rotatably connected to the inner wall of the supporting table through a shaft seat; a turntable body is fixed on a section of shaft body of the turntable rotating shaft exposed outside the support table; aplurality of heating hole sites for vertically inserting bars are formed in the top surface of the turntable body; the plurality of heating hole sites are uniformly distributed along the circumferential direction of the turntable body; the turntable body is also provided with an arc-shaped heating channel; and the two channel walls of the heating channel are arranged on the two sides of the heating hole respectively. And a heating wire electrically connected with an external power supply is fixed on the side wall of the heating channel. According to the invention, the heating position of a hexagon bolt head is accurate, and production is orderly.

Description

technical field [0001] The invention relates to the technical field of bolt head heating, in particular to intermediate frequency heating equipment. Background technique [0002] During the bolt production process, one end of the raw material needs to be molded to form a hexagonal head, and the end to be pressed needs to be heated before molding, and the molding work can only be completed when the temperature reaches a certain temperature. [0003] For the heating of the existing bolt raw materials, one batch is heated at a time, and then the batch is taken away for molding one by one. The temperature of the last bolt hexagonal head to be pressed may not reach the standard, and the mold will be damaged during molding. Just need to reheat raw material, delay production speed. [0004] The comparative document with the publication number CN108817869B discloses a production process of torsional shear bolts, which also mentions the heating mechanism, which is combined with the ...

Problems solved by technology

[0003] For the heating of the existing bolt raw materials, one batch is heated at a time, and then the batch is taken away for molding one by one. The temperature of the last bolt hexagonal head to be pressed may not reach the standard, and the mold will be damaged during molding. It is necessary to reheat the raw materials, delaying the production speed

[0004] The comparative document with the publication number CN108817869B discloses a production process of torsional shear bolts, which also mentions the heating mechanism, which is combined with the conveying mechanism to achieve the effect of heating while transporting, but this is also a batch-by-batch. Batch heating, after the bar is heated, the last bar of the batch has a long waiting time for molding, and it is easy to cool in the air, resulting in the failure of subsequent molding and affecting the production progress
