Description

Technical Field

[0001] The utility model relates to the field of induction heating equipment, and more particularly to a cooling structure of induction heating equipment. Background Art

[0002] Induction heating equipment converts electrical energy into heat energy using the principle of electromagnetic induction. It operates by passing an alternating current through an induction coil, generating an alternating magnetic field. This induces a current within a metal workpiece placed within the magnetic field, thereby rapidly heating the workpiece. Induction heating equipment offers advantages such as high heating efficiency, rapid heating speed, easy temperature control, and the ability to achieve localized heating. It is widely used in metal processing, heat treatment, smelting, and other fields.

[0003] In some small, simple induction heating devices, the heating coil is exposed to the outside to reduce costs and simplify the structure. For example, in small metal craft workshops, induction heating equipment is used to locally heat small metal parts, and in laboratories use induction heating equipment to facilitate observation of the status of the heated workpiece. However, such induction heating equipment usually only has a fan installed around the coil to dissipate heat, which is not very effective. This can keep the heating coil at high temperatures for a long time, eventually causing damage. In addition, the surface temperature of the heating coil after processing the workpiece is very high, and workers can easily suffer burns if they accidentally touch it.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a cooling structure for an induction heating device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a cooling structure for an induction heating device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling structure of an induction heating device, wherein the induction heating device is divided into multiple modules, each module has a separate heating coil and cooling assembly, and the cooling structure of the induction heating device also includes a base, the top two sides of the base are fixed to the cooling assembly through support plates, the cooling assembly is groove-shaped, and a lifting component is provided on the top to drive the heating coil to move up and down. When in use, the heating coil is placed under the cooling assembly and sleeved on the periphery of the workpiece fixed on the base to heat the workpiece. When cooling, the heating coil is moved upward and moved into the cooling assembly for cooling.

[0007] Preferably, the cooling assembly includes an annular shell fixed to the head of the support plate, a plurality of small holes are opened on the inner surface of the annular shell, and an air cooler is installed on the back of the annular shell to blow cold air toward the heating coil from all angles.

[0008] Preferably, the lifting component includes an N-shaped plate fixed on both sides of the annular shell, and an electric telescopic rod for driving the heating coil to move up and down is fixedly connected to the bottom surface of the N-shaped plate.

[0009] Preferably, a power supply is installed on the back of the heating coil for connecting the neutral wire and the live wire on the heating coil. Connecting plates are fixedly connected at both sides of the top. The top of the connecting plate is fixed to the end of the electric telescopic rod. An external wire is installed in the middle of the top of the power supply.

[0010] Preferably, an anti-winding component is installed on the top of the annular shell to avoid winding of external wires and reduce the workload of the staff.

[0011] Preferably, the anti-winding component includes a vertical tube body fixed to the back of the annular shell by an L-shaped plate, and the external wire passes through it. An annular plate is welded on the outer wall of the vertical tube body near the top, and a plurality of springs distributed in a circular array are installed on the top of the annular plate. The top of the spring is fixedly connected to a circular plate, and the center of the circular plate is fixed to the external wire.

[0012] Preferably, both sides of the top of the annular plate are fixedly connected to guide rails, and both sides of the circular plate are slidably connected to the guide rails through sliders, and the guide rails and sliders maintain the up and down linear movement of the annular plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The heating coil of the utility model can be cooled from all sides, which has a better cooling effect. Moreover, after heating, the heating coil will move to the inside of the cooling component for cooling, avoiding contact with the staff, thereby solving the problem that the heat dissipation effect of the existing induction heating equipment in the background technology is not very good, which will keep the heating coil in a high temperature state for a long time and eventually cause it to be damaged. In addition, the surface temperature of the heating metal ring is high after processing the workpiece. If the staff accidentally touches it, it is easy to be burned.

[0015] 2. The utility model installs an anti-winding component on the top of the annular shell to avoid the entanglement of external wires and reduce the workload of the staff;

[0016] 3. When the circular plate moves up and down, the utility model drives the slider to move up and down. The slider slides up and down along the guide rail to maintain the linear movement of the annular plate, thereby maintaining the linear expansion and contraction of the spring, preventing the spring from being damaged by oblique pulling.

[0028] like Figure 1-4 As shown, the utility model provides a cooling structure of an induction heating device. The induction heating device is divided into multiple modules, each module has a separate heating coil 1 and a cooling component 2. The cooling structure of the induction heating device also includes a base 3. The top sides of the base 3 are fixed to the cooling component 2 through support plates 4. The cooling component 2 is groove-shaped, and a lifting component 5 is provided on the top to drive the heating coil 1 to move up and down. When in use, the heating coil 1 is placed under the cooling component 2 and sleeved on the periphery of the workpiece fixed on the base 3 to heat the workpiece. When cooling, the heating coil 1 is moved upward and moved into the cooling component 2 for cooling.

[0029] When in use, first fix the workpiece on the top of the base 3, then use the lifting component 5 to drive the heating coil 1 to move downward, extend the heating coil 1 from the cooling component 2, and thus put it on the outer ring of the workpiece, and the workpiece is heated by the heating coil 1. After the heating is completed, the heating coil 1 can be driven to move upward by the electric telescopic rod 502, so that it can be retracted into the cooling component 2 for cooling. Since it is inside the cooling component 2, the heating coil 1 can be cooled from all sides, and the cooling effect is better. Moreover, after heating, the heating coil 1 will move to the inside of the cooling component 2 for cooling, avoiding contact with the staff.

[0030] The cooling assembly 2 includes an annular shell 201 fixed to the head of the support plate 4, and a plurality of small holes 202 are opened on the inner surface of the annular shell 201. An air cooler 203 is installed on the back of the annular shell 201. The lifting component 5 includes an N-shaped plate 501 fixed on both sides of the annular shell 201. An electric telescopic rod 502 that drives the heating coil 1 to move up and down is fixedly connected to the bottom surface of the N-shaped plate 501. A power supply 6 is installed on the back of the heating coil 1 for connecting the neutral wire and the live wire on the heating coil 1. Connecting plates 7 are fixedly connected at both sides of the top thereof. The top of the connecting plate 7 is fixed to the end of the electric telescopic rod 502, and an external wire 8 is installed in the middle of the top of the power supply 6.

[0031] That is, during cooling, the electric telescopic rod 502 drives the connecting plate 7 to move upward, thereby driving the power supply 6 and the heating coil 1 to move upward, and the heating coil 1 enters the space surrounded by the annular shell 201 of the cooling component 2, and the air cooler 203 blows cold air into the annular shell 201, and finally flows out from the small holes 202 on the inner surface of the annular shell 201. In this way, the cold air is diverted through the small holes 202, and can be blown to the heating coil 1 at different angles, thereby improving the cooling effect of the heating coil 1, and can also cool the power supply 6 at the same time. The length of the external wire 8 of the power supply 6 is long enough to leave space for the power supply 6 to move up and down.

[0032] However, an external wire 8 that is too long is very likely to get tangled when moving up and down, which requires staff to frequently deal with the tangling. For this reason, the utility model installs an anti-winding component 9 on the top of the annular shell 201 to avoid the tangling of the external wire 8. The anti-winding component 9 includes a vertical tube body 907 fixed to the back of the annular shell 201 through an L-shaped plate 901, and the external wire 8 passes through it. An annular plate 902 is welded to the outer wall of the vertical tube body 907 near the top, and a plurality of springs 903 distributed in a circular array are installed on the top of the annular plate 902. The top of the spring 903 is fixedly connected to a circular plate 904, and the center of the circular plate 904 is fixed to the external wire 8.

[0033] That is, in the initial state, the heating coil 1 and the power supply 6 are placed in the cooling assembly 2 above, and the spring 903 on the circular plate 904 uses its elastic supporting force to support the circular plate 904 to a certain height, thereby straightening the external wire 8 to prevent it from being entangled. When the heating coil 1 and the power supply 6 move downward to heat the workpiece, the power supply 6 will pull the external wire 8 down (the external wire 8 in the attached figure is in a pulled-down state), and the spring 903 will be compressed under the force to cooperate with the movement of the power supply 6. When the heating coil 1 and the power supply 6 move upward to reset after heating, the spring 903 will also use its elasticity to reset the circular plate 904, thereby straightening the external wire 8 again.

[0034] Furthermore, both sides of the top of the annular plate 902 are fixedly connected to the guide rails 905, and the two sides of the circular plate 904 are slidably connected to the guide rails 905 through sliders 906, that is, when the circular plate 904 moves up and down, it will drive the sliders 906 to move up and down, and the sliders 906 slide up and down along the guide rails 905 to maintain the linear movement of the annular plate 902, thereby maintaining the linear expansion and contraction of the spring 903, and preventing the spring 903 from being damaged by being pulled obliquely.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
