Description

Technical Field

[0001] This utility model relates to the technical field of medium frequency induction furnace equipment, and in particular to a coil lead-out side clamping mechanism for a medium frequency induction furnace. Background Technology

[0002] A medium-frequency induction furnace consists of main components such as an upper furnace body, a lower furnace body, an induction coil, and a relay. The upper furnace body includes the furnace shell and upper refractory cement. The induction coil includes a current-carrying conductor, insulating strip, coil leads, and insulating platform. The relay includes a magnetic yoke and coil pressing blocks. The medium-frequency induction furnace utilizes the principle of induction heating. Alternating current flows through the induction coil, causing a change in the magnetic field, which in turn heats and melts the metal. However, during the energizing process, the induction coil generates electromagnetic force, leading to vibrations in the coil.

[0003] Currently, the coil clamps are distributed between the relays to secure the induction coil. Due to the unique structure of the coil lead-out side, no clamps are installed there. When the coil is energized, the electromagnetic force increases the vibration amplitude, leading to breakage of the upper insulation platform and cracks in the cement connecting the coil cement to the upper furnace body refractory cement. This significantly shortens the service life of the insulation platform and refractory cement. Furthermore, increased coil vibration generates more noise, posing a noise hazard to operators. Moreover, without clamps to secure the coil lead-out side, the coil may rebound, causing insulation damage and shortening the lifespan of the coil insulation. Utility Model Content

[0004] The purpose of this invention is to provide a coil lead-out side clamping mechanism for a medium-frequency induction furnace, which aims to solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a coil lead-out side clamping mechanism for a medium-frequency induction furnace, including a medium-frequency induction furnace body and an induction coil disposed on the medium-frequency induction furnace body;

[0007] The side of the medium-frequency induction furnace body is provided with a coil lead-out side clamping mechanism, which includes a support body, a pressure block, and an elastic component;

[0008] The support body is installed on the medium frequency induction furnace body, the top of the pressure block is rotatably installed on the support body, one side of the pressure block is used to press the coil lead-out side, the elastic component is provided on the support body and connected to the pressure block, and the elastic component always has the tendency to drive the pressure block to rotate and press down.

[0009] In one possible implementation, the elastic component includes a connecting rod and a spring, a first end of the connecting rod being connected to the pressure block, a second end of the connecting rod extending movably through to the outside of the support body, a limiting element being installed on the second end of the connecting rod, and the spring being sleeved on the outside of the connecting rod and located between the limiting element and the support body.

[0010] In one possible implementation, a hinged arm is mounted on the support body, and the top of the pressure block is hinged to the hinged arm.

[0011] In one possible implementation, the spring is a compression spring.

[0012] In one possible implementation, the support is welded and fixed to the inner side of the medium-frequency induction furnace body.

[0013] In one possible implementation, a protruding pressing part is connected to one side of the pressure block, and the bottom end face of the protruding pressing part is used to press the coil lead-out side.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] In this invention, the coil lead-out side clamping mechanism can fix the position of the coil at the lead-out side, avoiding large vibration amplitudes of the coil during energization and under the action of electromagnetic force. This prevents the upper insulation platform of the coil from breaking due to large vibration amplitudes, and also prevents cracks in the cement at the connection between the coil cement and the upper furnace body refractory cement, thereby improving the service life of the insulation platform and refractory cement. In addition, it can also avoid noise from coil vibration, effectively preventing noise hazards for on-site operators. Furthermore, when the coil at the lead-out side is clamped by the pressure block, it can prevent the coil from rebounding, thus solving the problem of insulation damage and shortened coil insulation service life at this point.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] use Figure 1 This paper describes a coil lead-out side clamping mechanism for a medium-frequency induction furnace. Figure 1 This is a cross-sectional view of the present invention. The coil lead-out side clamping mechanism for the medium-frequency induction furnace can be installed on the coil lead-out side of the medium-frequency induction furnace body 1 to clamp and position the coil on the coil lead-out side.

[0025] First, use Figure 1 , Figure 2 and Figure 3 The overall structure of the coil lead-out side clamping mechanism for the medium-frequency induction furnace is described. Figure 1 This is a cross-sectional structural diagram of the present invention. Figure 2 This is a schematic diagram of the coil lead-out side clamping mechanism 2 in this utility model. Figure 3 This is a top view of the present invention.

[0026] like Figure 2 As shown. The coil lead-out side clamping mechanism of the medium-frequency induction furnace includes a medium-frequency induction furnace body 1 and an induction coil disposed on the medium-frequency induction furnace body 1. The medium-frequency induction furnace body 1 utilizes the principle of induction heating. By circulating alternating current through the induction coil, the magnetic field changes, thereby heating and melting the metal contained inside the medium-frequency induction furnace body 1.

[0027] The medium-frequency induction furnace body 1 includes an upper furnace body and a lower furnace body. Refractory cement 101 is provided at the top of the upper furnace body, and an insulating platform 102 is provided at the top of the induction coil. All of the above are existing technologies, and their working principles and functions will not be described in detail.

[0028] The side of the medium frequency induction furnace body 1 is provided with a coil lead-out side clamping mechanism 2, which is used to clamp and position the coil on the coil lead-out side to avoid the coil from generating a large vibration amplitude.

[0029] Regarding the specific structure and working principle of the coil lead-out side clamping mechanism 2, the specific coil lead-out side clamping mechanism 2 includes a support body 201, a pressure block 202, and an elastic component.

[0030] The support body 201 can be installed on the medium-frequency induction furnace body 1. Specifically, the support body 201 is integrated with the medium-frequency induction furnace body 1, that is, the support body 201 can be welded and fixed to the inner side of the medium-frequency induction furnace body 1. The support body 201 can be used to install the pressure block 202 and the elastic component.

[0031] Regarding the specific installation structure and working principle of the pressure block 202 and the elastic component, the top of the pressure block 202 can be rotatably mounted on the support body 201. One side of the pressure block 202 is used to press the coil lead-out side; specifically, a protruding pressing part 203 is connected to one side of the pressure block 202, and the bottom end face of the protruding pressing part 203 is used to press the coil lead-out side. The elastic component is provided on the support body 201 and connected to the pressure block 202. The elastic component always has a tendency to drive the pressure block 202 to rotate and press down, such as... Figure 2 As shown, specifically, the elastic component drives the pressure block 202 and the protruding pressing part 203 to rotate counterclockwise, so that the pressure block 202 and the protruding pressing part 203 have a clamping function, which can clamp and position the coil on the coil lead-out side.

[0032] In this embodiment, through the cooperation of the support body 201, the pressure block 202, and the elastic component, the support body 201 is installed on the medium-frequency induction furnace body 1. The elastic component drives the pressure block 202 and the protruding lower pressure part 203 to rotate counterclockwise, and presses the protruding lower pressure part 203 towards the coil lead-out side, thereby fixing the position of the coil at the coil lead-out side. This avoids the coil from generating a large vibration amplitude during the energization process and under the action of electromagnetic force, thus preventing the upper insulating platform 102 of the coil from breaking due to large vibration amplitude, and also preventing the cement at the connection between the coil cement and the upper furnace body refractory cement 101 from cracking, thereby improving the service life of the insulating platform 102 and the refractory cement 101.

[0033] In addition, by fixing the position of the coil at the lead-out side, coil vibration can be effectively avoided, that is, the noise generated by the coil vibration is avoided, and the operators on site can also effectively avoid noise hazards.

[0034] Furthermore, when the coil at the lead-out side is pressed tightly by the pressure block 202, the coil can be prevented from rebounding, thus solving the problem of insulation damage at this point and shortening the service life of the coil insulation.

[0035] In some embodiments, such as Figure 2 As shown. Figure 2 This is a schematic diagram of the coil lead-out side clamping mechanism 2 in this utility model. Regarding the specific structure and working principle of the elastic component, the elastic component includes a connecting rod 3 and a spring 4.

[0036] The first end of the connecting rod 3 is connected to the pressure block 202. Specifically, the first end of the connecting rod 3 can be hinged to the pressure block 202.

[0037] The second end of the connecting rod 3 extends movably through to the outside of the support body 201. A limiting element 5 is installed on the second end of the connecting rod 3. The spring 4 can be a compression spring, which is sleeved on the outside of the connecting rod 3 and located between the limiting element 5 and the support body 201. The first end of the spring 4 is fixedly connected to the side of the support body 201, and the second end of the spring 4 is fixedly connected to the side of the limiting element 5. Figure 2 As shown, the spring 4, which is a compression spring, always has the tendency to drive the connecting rod 3 and the pressure block 202 to move towards the right side of the medium frequency induction furnace body 1. Thus, the connecting rod 3 moving to the right can drive the pressure block 202 and the protruding lower pressure part 203 to rotate counterclockwise. The protruding lower pressure part 203 can press the coil on the coil lead-out side.

[0038] In this embodiment, the spring 4 drives the connecting rod 3 to move, thereby the connecting rod 3 drives the pressure block 202 to press and position the coil at the coil lead-out side.

[0039] In some embodiments, such as Figure 2 As shown. Figure 2 This is a schematic diagram of the coil lead-out side clamping mechanism 2 of this utility model. To allow the clamping block 202 to be rotatably mounted on the support body 201, a hinged arm 6 is mounted on the support body 201, and the top of the clamping block 202 is hinged to the hinged arm 6. In this embodiment, through the cooperation of the hinged arm 6 and the clamping block 202, the clamping block 202 can be rotatably mounted on the support body 201, thereby facilitating the clamping function of the clamping block 202 and the protruding lower clamping part 203.
