Description

Technical Field

[0001] The present invention relates to the technical field of heating and welding, and in particular to a high-frequency induction heating device. Background Art

[0002] Electromagnetic induction heating, or simply induction heating, is a method of heating conductor materials such as metal materials. It is mainly used for metal hot working, heat treatment, welding and melting. It uses the method of electromagnetic induction to generate current inside the material to be heated, and relies on the energy of these eddy currents to achieve the heating purpose. The principle of a high-frequency induction heating device is to use the large current of high frequency waves emitted by it to flow through the heating induction coil wound into an annular state or the required shape, and achieve the purpose of rapid heating through the powerful eddy current energy generated by the coil.

[0003] However, in the process of heating a metal rod by a coil in a traditional high-frequency induction heating device, due to the relatively fast temperature rise, due to the effect of thermal expansion and contraction, the surface objects of the metal rod such as rust, sediment or other impurities are squeezed due to the expansion of the metal rod itself. After being squeezed, the surface objects will break away from the metal rod under the action of external force and scatter on the periphery of the high-frequency induction heating device, resulting in a large amount of rust, sediment or other impurities accumulating on the periphery of the high-frequency induction heating device, polluting the environment around the processing site. Summary of the Invention

[0004] Based on this, it is necessary to provide a high-frequency induction heating device for the technical problem of how to collect the surface objects that fall from the surface of the metal rod due to heating and scatter on the periphery of the high-frequency induction heating device.

Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

The interface panel 112 is provided with a first interface 1121 and a second interface 1122. The coil 200 is provided with a first connecting pipe 210 and a second connecting pipe 220. The first connecting pipe 210 is connected to the first interface 1121, and the second connecting pipe 220 is connected to the second interface 1122. A first socket 110-1 and a second socket 110-2 are also provided on the heating operation surface 110. The receiving member 300 includes a first insertion rod 310, a second insertion rod 320, and a telescopic expansion member 330. The first insertion rod 310 and the second insertion rod 320 are respectively connected to the telescopic expansion member 330 and are located on the same side of the telescopic expansion member 330.

The third expansion body 334 half-wraps the second expansion body 333 and is slidably connected to the second expansion body 333. The distance between the outside of the coil 200 and the interface panel 112 is less than the sum of the widths of the seat body 331, the first expansion body 332, the second expansion body 333, and the third expansion body 334. The length of the first expansion body 332 is greater than the diameter of the coil.

[0021] The high-frequency induction heating device 10 increases the area of ​​the telescopic unfolding member 330 formed by the base 331, the first unfolding body 332, the second unfolding body 333 and the third unfolding body 334 by opening the telescopic unfolding member 330, and the vertical projection of the coil 200 will be located in the telescopic unfolding member 330 after opening. In this way, when the coil 200 heats the metal rod, the surface objects of the metal rod, such as rust, mud or other impurities, will fall into the telescopic unfolding member 330 after opening due to the heat, specifically, fall into the base 331, the first unfolding body 332, the second unfolding body 333 and the third unfolding body 334, thereby avoiding rust, mud or other impurities from falling directly on the periphery of the processing site, thereby making the environment around the processing site neat and orderly, and also improving the processing efficiency from the side; at the same time, when the metal rod does not need to be heated, the telescopic unfolding member 330 can be folded up without taking up space, and the overall equipment is reasonably compact.

[0022] To facilitate assembly and disassembly, in one embodiment, the seat body 331 is provided with a first screw hole 3311 and a second screw hole 3312, and the first plug rod 310 and the second plug rod 320 are respectively provided with external threads, the first plug rod 310 is screwed into the first screw hole 3311, and the second plug rod 320 is screwed into the second screw hole 3312. This can facilitate the installation and disassembly of the receiving member 300, and is particularly suitable for the packaging and transportation of complete machine parts.

[0023] To facilitate opening or closing the telescopic unfolding member 330, in one embodiment, the seat body 331 is a rectangular parallelepiped structure, and the first unfolding body 332 is a hollow rectangular parallelepiped structure with one side open. Further, the two opposite side walls of the seat body 331 are provided with a first slide groove 3313, and the two opposite inner side walls of the first unfolding body 332 are provided with a first slide rail 3321, and the first slide rail 3321 is embedded in the first slide groove 3313 and is slidably connected to the first slide groove 3313.

Further, the two opposite outer side walls of the first unfolding body 332 are provided with a second slide groove 3322, and the two opposite inner side walls of the second unfolding body 333 are provided with a second slide rail 3331, and the second slide rail 3331 is embedded in the second slide groove 3322 and is slidably connected to the second slide groove 3322. Further, the third unfolding body 334 is a hollow rectangular parallelepiped structure with one side open. Furthermore, the second unfolding body 333 has two opposite outer side walls with third slide grooves 3332, and the third unfolding body 334 has two opposite inner side walls with third slide rails 3341-1, which are embedded in the third slide grooves 3332 and slidably connected to the third slide grooves 3332. In this way, the telescopic unfolding member 330 can be opened or closed in a semi-wrapped manner and in a sliding connection manner. At the same time, the structural design is more in line with industrial production and application, can be made of steel or plastic stamping, and is easy and quick to assemble.

[0024] In one embodiment, to collect rust, sediment or other impurities more effectively, the third deployment body 334 includes a bottom plate 3341, a front plate 3342, a cover plate 3343 and two side plates 3344.

The cover plate 3343 is rotatably connected to the front plate 3342. The bottom plate 3341, the front plate 3342, the cover plate 3343 and the two side plates 3344 together form a hollow rectangular parallelepiped structure with an opening on one side. The two side plates 3344 are respectively provided with third slide rails 3341-1. In this way, when the first deployment body 332, the second deployment body 333 and the third deployment body 334 are fully deployed, the third deployment body 334 can be further opened to increase the area of the third deployment body 334, that is, the front plate 3342 and the cover plate 3343 can be rotated and opened away from the bottom plate 3341. In this way, the area of the third deployment body 334 can be further increased, so as to receive rust, sediment or other impurities in a larger range.

[0025] In one embodiment, to prevent the rust, sediment or other impurities collected in the third deployment body 334 from falling due to the vibration of the machine or external force, a limiting rubber strip 3345 is convexly provided at the edge area of the cover plate 3343. The limiting rubber strip 3345 can be bonded to the edge area of the cover plate 3343. In this way, the height of the edge area of the cover plate 3343 is raised by the limiting rubber strip 3345, preventing the rust, sediment or other impurities collected in the third deployment body 334 from falling due to the vibration of the machine or external force.

[0026] Furthermore, the high-frequency induction heating device is further provided with a controller for controlling the overall operation of the high-frequency induction heating device. The controller is electrically connected to the heater body. The heater body is used to generate high-frequency current. The heater body is electrically connected to the coil through an internal wire. The high-frequency current generated by the heater body is conducted to the coil through the internal wire, so that the coil heats the workpiece to be heated, such as a metal rod.

[0027] Furthermore, the high-frequency induction heating device is also provided with a coil fixing mechanism and a coil. The controller is electrically connected to the heater body, and the heater body is electrically connected to the coil through the coil fixing mechanism. The coil fixing mechanism includes a fixing box, a blocking block, and two fixing components. Threaded holes are formed at both ends of the fixing box, and the blocking block is located in the middle area of the fixing box and is connected to the fixing box. A plurality of fixing holes are formed on one side of the fixing box, and two wiring holes are formed on the side of the fixing box opposite to the fixing holes. Two receiving cavities are formed in the fixing box, and the two receiving cavities are respectively located on both sides of the blocking block. Each wiring hole, each threaded hole, and some of the fixing holes communicate with one receiving cavity. Each fixing component includes a threaded rod, a receiving block, a plurality of pressing plates, and an elastic member. Part of the threaded rod, the receiving block, and the elastic member are received in one receiving cavity. One end of the threaded rod is connected to the receiving block, a plurality of pressing plates are connected to the receiving block, the end of the receiving block away from the threaded rod is connected to the elastic member, and the end of the elastic member away from the receiving block is connected to the blocking block. Each pressing plate is inserted into a fixing hole. Both the receiving block and the pressing plates are made of conductive materials. One end of the coil is inserted into a fixing hole and is electrically connected to a receiving block through a pressing plate, and the other end of the coil is inserted into a fixing hole and is electrically connected to another receiving block through a pressing plate. The first wiring end of the heater body is inserted into a wiring hole and is electrically connected to a receiving block, and the second wiring end of the heater body is inserted into the other wiring hole and is electrically connected to another receiving block. In the high-frequency induction heating device of this embodiment, by rotating the threaded rod in one fixing component to drive the receiving block to slide in the receiving cavity, the receiving block sliding in the receiving cavity drives the pressing plate to move in the fixing hole to fixedly clamp one end of the coil. Similarly, by rotating the threaded rod in the other fixing component to drive the receiving block to slide in the receiving cavity, the receiving block sliding in the receiving cavity drives the pressing plate to move in the fixing hole to fixedly clamp the other end of the coil. The plurality of fixing holes formed in the fixing box are used to accommodate coils with different numbers of turns, and coils with different numbers of turns can be inserted into different fixing holes, greatly improving the convenience of replacing the induction coil with different numbers of turns of the high-frequency induction heater.

[0028] The coil fixing mechanism is used to fix the coil. Specifically, one end of the threaded rod is connected to the receiving block, several pressing plates are all connected to the receiving block, the end of the receiving block away from the threaded rod is connected to the elastic member, and the end of the elastic member away from the receiving block is connected to the blocking block. In this embodiment, the elastic member is an elastic rubber. In another embodiment, the elastic member is a compression spring. Each pressing plate is inserted into a fixing hole. Both the receiving block and the pressing plate are made of conductive materials. One end of the coil is inserted into a fixing hole and electrically connected to a receiving block through a pressing plate, and the other end of the coil is inserted into a fixing hole and electrically connected to another receiving block through a pressing plate. The first wiring terminal of the heater body is inserted into a wiring hole and electrically connected to a receiving block, and the second wiring terminal of the heater body is inserted into another wiring hole and electrically connected to another receiving block. By rotating the threaded rod in one fixing component, the receiving block is driven to slide in the receiving cavity. The sliding of the receiving block in the receiving cavity drives the pressing plate to move in the fixing hole to fixedly clamp one end of the coil. Similarly, by rotating the threaded rod in another fixing component, the receiving block is driven to slide in the receiving cavity. The sliding of the receiving block in the receiving cavity drives the pressing plate to move in the fixing hole to fixedly clamp the other end of the coil. The multiple fixing holes provided in the fixing box can accommodate coils with different numbers of turns. Coils with different numbers of turns can be inserted into different fixing holes, greatly improving the convenience of replacing the induction coil with different numbers of turns in the high-frequency induction heater.

[0029] In order to increase the structural stability of the high-frequency induction heater, in one embodiment, the high-frequency induction heater further includes a support frame, and the controller, the heater body and the fixing box are all connected to the support frame. Specifically, the support frame includes a support plate and several support columns. The several support columns are all connected to the support plate, and the several support columns are evenly distributed around the support plate to evenly bear the weight of the support plate. The controller, the heater body and the fixing box are all connected to the support plate. In this way, the support frame increases the structural stability of the high-frequency induction heater.

[0030] In order to improve the clamping degree of the coil fixing mechanism on the coil, in one embodiment, the pressing plate is an arc-shaped plate. The arc-shaped plate increases the contact area between the pressing plate and the coil, increases the friction between the pressing plate and the coil, thereby improving the clamping degree of the coil fixing mechanism on the coil. Further, anti-slip lines are provided on the inner side wall of the fixing hole. The anti-slip lines increase the anti-slip performance of the fixing box, increase the friction between the coil and the fixing box, thereby improving the clamping degree of the coil fixing mechanism on the coil. In this way, the clamping degree of the coil fixing mechanism on the coil is improved, and the working stability of the coil fixing mechanism is improved.

[0031] In order to increase the working stability of the coil fixing mechanism, in one embodiment, both side walls of the receiving chamber are provided with sliding grooves, and both sides of the receiving block are provided with sliding blocks, each sliding block is inserted in a sliding groove and is slidably connected to the fixing box.

In another embodiment, both side walls of the receiving chamber are provided with sliding edges, and both sides of the receiving block are provided with sliding grooves, and each sliding edge is inserted in a sliding groove and is slidably connected to the receiving block. Further, both side walls of the receiving chamber are provided with two sliding edges, and both sides of the receiving block are provided with two sliding grooves, each sliding edge is inserted in a sliding groove and is slidably connected to the receiving block.
