[0001] The utility model relates to the technical field of catalytic oil slurry filtering equipment, in particular to a high-frequency induction heating equipment for metal heat treatment. Background Art

[0002] High-frequency induction heating is a method of heating metal workpieces using the principle of electromagnetic induction. During the manufacturing process of metal workpieces, high-frequency heating can speed up the efficiency of the workpiece quenching process. This type of heating equipment usually installs a heating coil on the high-frequency heater, and inserts the rod-shaped metal workpiece into the inner area of ​​the heating coil. At this time, eddy currents are generated around the metal workpiece, and then the metal workpiece is Joule heated, causing it to quickly enter a red temperature state.

[0003] In actual use, most of the existing high-frequency induction heating equipment uses a heating coil of fixed length, which will have disadvantages when processing metal workpieces of different lengths. If the length of the metal workpiece becomes smaller and the length of the heating coil is greater than the length of the metal workpiece, a part of the heating coil will be in an ineffective heating state, wasting electric energy. If the length of the metal workpiece becomes larger and the length of the heating coil is less than the length of the metal workpiece, part of the metal workpiece will not be inside the heating coil, and the metal workpiece cannot be fully heated. Therefore, the fixed-length heating coil is difficult to meet the processing conditions of metal workpieces of different lengths, which significantly reduces the applicability of the heating equipment.

[0004] In view of this, the present application proposes a high-frequency induction heating device for metal heat treatment that is capable of heating metal workpieces of different lengths and thereby improving the applicability of the heating device. Summary of the invention

[0029] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1-Figure 4As shown, a high-frequency induction heating device for metal heat treatment proposed by the utility model comprises a base 1, at least four support columns 3 are fixedly installed on the top of the base 1, and top plates 4 are fixedly installed on the tops of several support columns 3. The base 1, support columns 3 and top plates 4 together constitute the main support structure of the heating device, and a clamp 2 is slidably installed on the top plate 4, and the bottom end of the clamp 2 is slidably connected to the base 1 to ensure that the clamp 2 can be stably slidably assembled on the support structure, so as to facilitate lateral adjustment thereof; a third heater 8 is fixedly installed on the bottom of the top plate 4, and a first heater 5, a second heater 6 and a third heater 7 are provided on one side of the third heater 8. Heater 7, the first heater 5 and the second heater 7 can be raised and lowered, and the three heaters are fixedly mounted with heating coils 10. When the three heaters are at the same height, the three heating coils 10 form an integral long coil, which can effectively and comprehensively heat the long metal workpiece 9 that penetrates into its inner area. After the height of the first heater 5 and the second heater 7 is adjusted, the three coils are split into independent short coils, which can heat the short metal workpiece 9, ensuring that the heating equipment can meet the heating operation of metal workpieces 9 of different lengths.

[0032] Furthermore, a height adjustment frame 6 is installed on the top plate 4, and the height adjustment frame 6 consists of a lifting plate 61, a limiting connecting rod 63 and a reciprocating screw rod 62. The above-mentioned limiting connecting rod 63 is movably arranged on the top plate 4, and the top end of the limiting connecting rod 63 is fixedly connected to the lifting plate 61, and the bottom end of the limiting connecting rod 63 is fixedly connected to the corresponding heater, ensuring that the heater can be stably suspended under the top plate 4; the above-mentioned reciprocating screw rod 62 passes through the lifting plate 61 and is threadedly connected thereto, and the bottom end of the reciprocating screw rod 62 is rotatably connected to the top of the top plate 4. After rotating the handwheel at the top of the reciprocating screw rod 62, the lifting plate 61 can be driven to be raised and lowered under the limit of the limiting connecting rod 63, so as to facilitate the adjustment of the height of the first heater 5, the second heater 7 and the corresponding heating coil 10.

[0033] Furthermore, the clamp 2 includes a plurality of clamping seats 21, and an L-shaped connecting frame 22 is fixed between two adjacent clamping seats 21, which can connect the plurality of clamping seats 21 into one, so as to facilitate synchronous lateral adjustment thereof; a U-shaped sliding sleeve 24 is fixedly installed on the clamping seat 21 close to the top plate 4, and the sliding sleeve is slidably connected to the top plate 4; a slider 23 is fixedly installed on the lower surface of the clamping seat 21 close to the base 1, and the slider 23 is slidably connected to the slide groove set on the top of the base 1, so as to effectively limit the clamp 2, ensure that it can stably slide and adjust laterally, and facilitate the adjustment of the depth of the metal processing part 9 inserted into the inner side of the heating coil 10.

[0034] Secondly, a quartz ring 211 is fixedly installed on the clamping seat 21, and a clamping hole 213 is provided on the quartz ring 211. A fixing bolt 215 is threadedly installed at one end of the clamping seat 21, and a lifting block 214 is movably installed in the clamping seat 21. One end of the lifting block 214 extends into the clamping hole 213. When the metal processing part 9 passes into the clamping hole 213, the fixing bolt 215 is adjusted to push the lifting block 214 to move to one side of the clamping hole 213. When the lifting block 214 is in close contact with the metal processing part 9, the metal processing part 9 can be locked and fixed to ensure that the metal processing part 9 can be firmly installed on the clamp 2.

[0035] It is worth mentioning that a plurality of heat dissipation channels 212 are drilled at one end of the clamping seat 21. The inner open end of the heat dissipation channel 212 is attached to the outer wall of the quartz ring 211. The quartz ring 211 is installed on the clamping seat 21. Its main purpose is to provide heat insulation. After the metal workpiece 9 is heated, the probability of heat conduction to the clamping seat 21 can be reduced. Combined with the heat dissipation channel 212, the heat dissipation effect can be accelerated. During the heating operation, when the clamp 2 is adjusted, the risk of scalding the hands can be reduced.

[0036] In this embodiment, the metal workpiece 9 is first passed through the clamping hole 213, and then turned to the fixing bolt 215, and the metal workpiece 9 is clamped by the lifting block 214 to ensure that the metal workpiece 9 can be firmly installed on the clamp 2, which is convenient for subsequent heating treatment. When heating metal workpieces 9 of different lengths, the heating coil 10 can be combined or split to meet the processing requirements of metal workpieces 9 of different lengths. The specific operation method is as follows:

[0037] For a long metal workpiece 9, multiple heating coils 10 should be combined into a long coil of an integrated structure. At this time, the metal workpiece 9 penetrates into the inner area of ​​the long coil. The combined long coil can ensure that the metal workpiece 9 is completely covered inside the coil structure, so that it can be effectively heated, which solves the problem that the traditional fixed-length coil cannot effectively heat the workpiece whose length is greater than the coil itself.

[0038] For metal processing parts 9 of small length, the present application can split the long coil of the above-mentioned integrated structure. At this time, the reciprocating screw 62 can be rotated first to drive the lifting plate 61 to be lifted and lowered. When the lifting plate 61 moves downward, it can drive the heater and the corresponding heating coil 10 to move downward, which is convenient for splitting the integrated long coil into multiple independent short coils, and then fix multiple metal processing parts 9 of small length on the corresponding clamping seats 21 respectively, and push the clamp 2 to one side of the short coil, so that multiple short metal processing parts 9 can be inserted into the corresponding short coils. Not only can multiple workpieces be heated at the same time, but the length of the coil is matched with the length of the workpiece, which solves the problem of ineffective heating and increased energy waste caused by the coil length being greater than the workpiece length. Therefore, the present application can perform effective and energy-saving heating treatment on metal processing parts 9 of different lengths, effectively improving the applicability of the heating equipment.

[0039] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
