[0020] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0021] like Figures 1 to 5As shown, a high-efficiency medium-frequency induction furnace of this embodiment includes a furnace body 1, and a pushing device 2 is provided on the periphery of the furnace body 1. The pushing device 2 is used to push the material into the furnace body 1. The pushing device 2 includes a main body 3, a power assembly 4 and a pushing assembly 5. The power assembly 4 is arranged on the main body 3. The power assembly 4 includes a motor 41 and a transmission member 42. The motor 41 drives the transmission member 42 to move. The transmission member 42 is arranged around the main body 3. The motor 41 makes the transmission member 42 form a closed loop and move in a cycle. The transmission member 42 can use a belt or a chain. A plurality of pushing assemblies 5 are arranged on the transmission member 42 at intervals, so that the pushing assemblies 5 are driven to move by the transmission member 42. The pushing assembly 5 includes a mounting seat 51, a push rod 52 and a spring 53. The mounting seat 51 is connected to the transmission member 42. The push rod 52 is inserted into the mounting hole 511 of the mounting seat 51. One end of the push rod 52 is provided with a rotating wheel 54 that presses against the side wall of the main body 3, and the other end is provided with a pushing portion 55. The spring is sleeved on the push rod and located in the mounting hole 511. The spring 53 presses against the pushing portion 55. The side wall of the main body 3 has a concave-convex curved surface 30. In the above technical solution, the motor 41 drives the transmission member 42 to rotate, thereby rotating the push assembly 5. When the push assembly 5 is located on the concave-convex curved surface 30, the rotating wheel 54 rolls on the concave-convex curved surface 30. When the rotating wheel 54 is located on the convex surface, the push rod 52 moves toward the furnace body 1, the spring 53 is stretched, and the push rod drives the pushing portion 55 to move toward the furnace body 1, thereby pushing the material rod in the material trough 10 of the furnace body 1 into the furnace body. When the roller 54 moves to the concave curved surface, the restoring force of the spring 53 resets the push rod. Through the above technical solution, the pusher assembly can be extended and retracted on the concave and convex surface, which is convenient for pushing materials without the need for a mechanical arm drive, thereby reducing the cost of use and maintenance.

[0022] In this embodiment, the main body 3 includes a first side portion 31, a second side portion 32 and an arc portion 33, the arc portion 33 connects the first and second side portions, the first side portion 31 faces the furnace body 1 and has a concave-convex curved surface 30, the second side portion 32 is away from the first side portion 31, and the surface of the second side portion 32 is a plane. Through the above technical solution, when the pusher assembly 5 moves to the second side portion 32, it will not telescopically move, so that it can remain stable. The pusher assembly 5 can be reversed by the arc portion 33. At least one motor 41 is arranged on the arc portion 33, and the motor 41 is arranged at both ends of the main body. The transmission member can be sleeved with the transmission wheel on the motor 41 to realize transmission. For example, the two arc portions 33 are respectively provided with a motor and a driven wheel, and the transmission member is sleeved on the driven wheel and the driving wheel of the motor. This is the basic structure of belt transmission and chain transmission, which is a conventional technical means in this field.

[0023] like Figure 3As shown, in this embodiment, at least part of the several pushing devices 2 has a clamping assembly 6 for clamping the bar material. The clamping assembly 6 is arranged at the end of the push rod 52. The extension and retraction of the push rod 52 can drive the clamping assembly 6 to move closer to or away from the furnace body 1. The clamping assembly 6 includes a driving cylinder 61, a transmission mechanism 62 and a clamping claw 63. The driving cylinder 61 is connected to the clamping claw 63 through the transmission mechanism 62, and drives the clamping claw 63 to open or close. When the clamping claw is closed, the material 30 can be clamped, and when it is opened, the material 30 can be released. When the clamping assembly 6 moves to the concave and convex curved surface position, when the clamping assembly 6 is close to the furnace body 1, the clamping claw 63 releases the material 30, so that it is located in the material trough 10 of the furnace body 1. When the clamping assembly 6 moves to the second side portion 32, the material is loaded into the clamping claw 63. In this way, the material can be pushed and loaded cyclically to improve the processing efficiency.

[0024] In this embodiment, the clamping claw 63 includes a first clamping arm 631 and a second clamping arm 632, a return spring 633 is provided between the first and second clamping arms, and the transmission mechanism 62 is connected to the first and second clamping arms respectively. The first and second clamping arms are clamped or released, and the return spring 633 is used to reset the clamping arms. The transmission mechanism 62 includes a first connecting rod 621 and a second connecting rod 622, the two ends of the first connecting rod 621 are respectively pivotally connected to the first clamping arm 631 and the sliding block 64 on the motor shaft of the driving cylinder 61, and the two ends of the second connecting rod 622 are respectively pivotally connected to the second clamping arm 632 and the sliding block 64. Through the above technical solution, the sliding block 64 can be driven to slide along a straight line by the driving cylinder 61, so that the first and second connecting rods pull the first and second clamping arms. The first clamping arm 631 and the second clamping arm 632 are respectively provided with an axial hole 65, and the axial hole 65 is pivotally connected to the housing 66 of the clamping assembly 6.

[0025] The first clamp arm 631 and the second clamp arm 632 are respectively provided with oppositely arranged slots 65, and the material 30 is arranged in the slots 65. The mounting seat 5 is provided with a slide rail 56, and the driving cylinder 61 is connected to the slide rail 56 through the matching portion 611, so that when the push rod drives the clamping assembly 6, it can be guided by the slide rail 56. The mounting seat 5 is connected to the transmission member 42 through the support portion 7, so that the mounting seat 5 is installed more stably.

[0026] A high-efficiency medium-frequency induction furnace in this embodiment can enable the pushing component to extend and retract on a concave and convex surface, which is convenient for pushing materials and does not require a mechanical arm drive, thereby reducing the cost of use and maintenance; in addition, it can discharge materials and improve the efficiency of discharging and pushing materials.
