[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a medium-frequency induction furnace, including a furnace body 1, a cover plate 11 rotatably connected to the upper end of the furnace body 1, and a rotating assembly 2 fixedly connected to one end of the furnace body 1 to facilitate the rotation of the furnace body 1 to pour molten iron. The rotating assembly 2 includes a motor 21 disposed on the outer side of the middle end of the furnace body 1, and a first gear 22 fixedly connected to the output shaft of the motor 21. The operation of the motor 21 drives the first gear 22 to rotate and provide power output. A second gear 23 meshes with the upper end of the first gear 22, and a rotating rod 24 is fixedly connected to the middle end of the second gear 23. The meshing of the first gear 22 and the second gear 23 drives the rotating rod 24 to rotate.

[0025] like Figure 1 and Figure 2 As shown, one end of the rotating rod 24 is rotatably connected to the support plate 25, and the outer end of the support plate 25 is fixedly connected to the protective cover 26. The end of the rotating rod 24 away from the support plate 25 passes through the protective cover 26. The support plate 25 and the protective cover 26 are used to protect the motor 21 and the first gear 22, etc.

[0026] like Figure 2As shown, a third gear 27 is fixedly connected to the end of the rotating rod 24 away from the support plate 25, and a fourth gear 28 is meshed at the lower end of the third gear 27. A fixing plate 29 is fixedly connected to the side of the fourth gear 28 near the furnace body 1, and the end of the fixing plate 29 near the furnace body 1 is fixedly connected to the furnace body 1. By using the meshing of the third gear 27 and the fourth gear 28, the fourth gear 28 drives the fixing plate 29 to rotate, thereby using the fixing plate 29 to drive the furnace body 1 to rotate under the support of the support rod 33.

[0027] like Figure 1 As shown, a support assembly 3 is provided at the lower end of the motor 21, and the support assembly 3 includes a hydraulic rod 31 provided at the lower end of the motor 21. A fixing block 32 is fixedly connected to the upper end of the hydraulic rod 31, and the upper end of the fixing block 32 is fixedly connected to the lower side of the motor 21. A support rod 33 is fixedly connected to the end of the fixing block 32 near the furnace body 1, and the end of the support rod 33 away from the fixing block 32 is rotatably connected to the furnace body 1. Activating the hydraulic rod 31 can push the fixing block 32 and the support rod 33 to move, thereby allowing the support rod 33 to push the furnace body 1 to move and adjust.

[0028] like Figure 1 As shown, a load-bearing plate 34 is fixedly connected to the lower end of the hydraulic rod 31, and bolts 35 are engaged inside both ends of the load-bearing plate 34 to facilitate the fixation and restriction of the hydraulic rod 31.

[0029] Working principle: When processing metal materials using a medium-frequency induction furnace, first open the cover plate 11, then place the metal material into the furnace body 1, and then close the cover plate 11 for heating and melting. After heating and melting, the hydraulic rod 31 is activated under the support of the load-bearing plate 34. After the hydraulic rod 31 is activated, the output shaft pushes the fixed block 32 and the support rod 33 to move the furnace body 1 upward. When the furnace body 1 is moved to a suitable height, the collecting device is pushed to the lower side of the furnace body 1. Then, with the assistance of the support plate 25 and the protective cover 26, the motor 21 is activated. After the motor 21 is activated, the output shaft drives the first gear 22 to rotate. After the first gear 22 rotates, it meshes with the second gear 23, driving the second gear 23 and the rotating rod 24 to rotate. The rotating rod 24 synchronously drives the third gear 27 to rotate. Then, by meshing the third gear 27 with the fourth gear 28, the fourth gear 28 drives the fixed plate 29 and the furnace body 1 to rotate. During the rotation of the furnace body 1, the cover plate 11 is opened, and the molten metal inside the furnace body 1 is poured out and injected into the collection device through the rotation of the furnace body 1. After the pouring is completed, the motor 21 is started, and its output shaft is rotated in the opposite direction to return the furnace body 1 to its original position. After the furnace body 1 returns to its original position, the collection device is moved out, and then the hydraulic rod 31 is started, so that the hydraulic rod 31 retracts and drives the fixed block 32 and the support rod 33 to move. The support rod 33 drives the furnace body 1 to move down and back to its original position. Then, the metal material is placed in the furnace body 1 for processing according to the above operation.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
