Description

Technical Field

[0001] The utility model relates to the technical field of red copper wire processing, in particular to a turning mechanism of a medium frequency smelting furnace. Background Art

[0002] A medium frequency melting furnace is a melting equipment that uses medium frequency current to generate induction heating. It is mainly used for melting and smelting metals. This furnace generates an alternating electromagnetic field through an induction coil, causing the metal to generate eddy currents under the action of the electromagnetic field, thereby generating heat to achieve heating and melting of the metal. It is often used in the processing of copper materials such as red copper wire.

[0003] For example, a turning device for a medium frequency smelting furnace disclosed in Chinese patent announcement number (CN207634924U) includes a worm shaft with spiral teeth cooperating with a turbine to solve the self-locking problem during the turning process; the supporting part of the smelting barrel is supported by bearings to solve the rotation problem of the smelting barrel; the right end of the support shaft adopts bevel gear transmission to solve the problem of transmission direction of the overall structure; a cylindrical rod is provided on gear B to solve the positioning problem of the smelting barrel during rotation; a plurality of teeth are provided on gear A to solve the problem of intermittent motion when gear A and gear B are meshed; the overall transmission structure adopts gear transmission to solve the problem of reliable fixed transmission of the equipment; the handle part is cylindrical to solve the problem of the operator's grip.

[0004] However, the above patent still has the problem of poor flip locking effect for the flipping device. For example, in the above patent, the overall transmission structure adopts gear transmission, and uses multiple sets of different gears to realize the flipping operation of the smelting furnace. In this method, self-locking is achieved only by different transmission methods between the matching gears. However, it cannot be used for a long time for self-locking. Too long time may easily lead to the collapse of the gear tooth surface, thereby affecting the subsequent meshing transmission effect and affecting the flipping of the smelting furnace.
