[0019] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0020] As Figures 1 to 3 shown in the embodiment of the angle-adjustable intermediate frequency melting furnace support frame of the utility model, the angle-adjustable intermediate frequency melting furnace support frame includes an outer cylinder 1 and a support 2. Rotating shafts 3 are symmetrically provided on both sides of the outer cylinder 1, and the rotating shafts 3 are rotatably connected to the support 2. A crucible 4 is fixedly connected inside the outer cylinder 1, an induction coil 5 is wound around the crucible 4, obliquely upward support rods 6 are fixedly connected to both sides of the support 2, the top ends of the support rods 6 are rotatably connected to a load-bearing plate 7, and a telescopic assembly 8 for adjusting the inclination of the outer cylinder 1 is provided between the middle of the load-bearing plate 7 and the lower part of the outer cylinder 1.

[0021] Specifically, when it is necessary to adjust the tilt angle of the smelting furnace, the telescopic assembly 8 is shortened, so that the bottom of the outer cylinder 1 rotates around the rotating shaft 3. By continuously shortening the telescopic assembly 8, the distance between the bearing plate 7 and the lower part of the outer cylinder 1 is reduced. When it is necessary to restore, the telescopic assembly 8 is elongated, the distance between the bearing plate 7 and the lower part of the outer cylinder 1 is increased, and the outer cylinder 1 is restored to the vertical state.

[0022] In an embodiment of the present application, preferably, the telescopic assembly 8 includes a fixed rod 81 and a lead screw 82. One end of the fixed rod 81 is hinged to the outer cylinder 1, the other end of the fixed rod 81 is rotatably connected to the lead screw 82, and the lead screw 82 is threadedly connected to the bearing plate 7, which is used to contract or extend the support distance between the bearing plate 7 and the hinged part of the outer cylinder 1 to adjust the tilt angle of the outer cylinder 1. After the angle is adjusted, due to the good stability of the threaded connection between the lead screw 82 and the bearing plate 7, there will be no slippage and rotation phenomenon, and the support is stable.

[0023] In an embodiment of the present application, preferably, two hinge plates 9 are fixedly connected to the lower part of the outer cylinder 1, a pin shaft 10 is fixedly connected between the two hinge plates 9, a rotating ring 11 is rotatably connected to the pin shaft 10, and the rotating ring 11 is fixedly connected to the fixed rod 81, which is used to make the fixed rod 81 rotate to adapt to the vertical angle between the lead screw 82 and the bearing plate 7 when the outer cylinder 1 is tilted.

[0024] In an embodiment of the present application, preferably, a reversible motor 12 is fixedly connected to the fixed rod 81, and the drive shaft of the reversible motor 12 is fixedly connected to the lead screw 82, which is used to drive the lead screw 82 to rotate to adjust the support distance between the bearing plate 7 and the hinged part of the outer cylinder 1.

[0025] In an embodiment of the present application, preferably, the fixed rod 81 and the reversible motor 12 are coaxial and fixedly connected to the tail of the reversible motor 12, with a simple structure and easy maintenance and operation.

[0026] In an embodiment of the present application, preferably, the crucible 4 is provided with a liquid pouring port 13 on the other side of the telescopic assembly 8 on the outer cylinder 1, which is used to pour the smelted metal liquid to avoid spillage.

[0027] In an embodiment of the present application, preferably, the hinged position of the fixed rod 81 is lower than the center point of the outer cylinder 1, and the height of the bearing plate 7 is higher than the position of the rotating shaft 3, making it easier to adjust the angle, with a small driving load, and also enabling the tilted angle to meet the requirements of a larger range.

[0028] In an embodiment of the present application, preferably, the induction coil 5 is hollow, and the outer cylinder 1 is provided with a heat dissipation window 14, which is used to introduce coolant and dissipate heat from the induction coil 5.

[0029] In summary, for the angle-adjustable intermediate frequency melting furnace support frame in the above embodiments of the present utility model, specifically, when it is necessary to adjust the tilt angle of the melting furnace, the reversible motor 12 is started to rotate, driving the lead screw 82 to rotate, so that the support distance between the load-bearing plate 7 and the hinge part is shortened. The outer cylinder 1 rotates around the rotating shaft 3, and the fixed rod 81 rotates around the pin shaft 10. The load-bearing plate 7 also adjusts its inclination angle and always remains perpendicular to the lead screw 82. When adjusted to the required angle, since the lead screw 82 and the load-bearing plate 7 are threadedly connected and always in a stable state, the support between the hinge part of the load-bearing plate 7 and the fixed rod 81 is stable, and the outer cylinder 1 will not rotate back, avoiding potential safety hazards. On the contrary, when the reversible motor 12 rotates to drive the lead screw 82 to rotate, the support distance between the hinge part of the load-bearing plate 7 and the fixed rod 81 becomes longer, and the inclination angle of the outer cylinder 1 gradually decreases until it returns to the vertical state. This device uses the threaded connection between the lead screw 82 of the telescopic assembly 8 and the load-bearing plate 7 to ensure the stable support of the telescopic assembly 8, prevent the outer cylinder 1 from rotating back when tilted, and ensure production safety.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
