Description
Technical Field
[0001] This utility model relates to the technical field of steel wire induction heating devices, and in particular to a steel wire induction heating device. Background Technology
[0002] A high-frequency induction heating machine is a device that uses a high-frequency current passing through an induction coil to generate a high-frequency magnetic field, inducing eddy currents within conductors such as metals, thereby generating heat. A powerful magnetic flux with rapidly changing polarity is generated within the high-frequency induction coil. When the metal to be heat-treated is placed within the high-frequency coil, the magnetic flux penetrates the entire metal object being heated. Within the induction-heated object, corresponding strong eddy currents are generated in the opposite direction to the induction heating current. Because the metal contains resistance, strong Joule heating energy is generated, causing the temperature of the induction-heated object to rise rapidly, thus achieving the purpose of heat treatment.
[0003] The inventors discovered during routine use of the high-frequency induction heating machine that when steel wire is passed through the machine, it needs to be heated by passing it through a spiral heating wire. Since the steel wire is suspended as it passes through the heating wire, it is easy for the steel wire to come into contact with the heating wire during heating, causing it to stick together and thus affecting the process. Utility Model Content

[0007] Preferably, a brush is fixedly connected to the inner wall of the limiting ring, and the brush is made of iron wire.
[0008] The effect achieved by the above-mentioned components is that, under the action of the brush, impurities on the surface of the steel wire are cleaned and scraped off, thereby achieving the cleaning effect.
[0009] Preferably, a scraper ring is fixedly connected to one end of the limiting ring, and the scraper ring is a rubber ring.

[0028] Example 1, as Figure 1 A steel wire induction heating device includes a heating machine 1, an operation panel 4 fixedly connected to the side of the heating machine 1, a spiral heating wire 6 fixedly connected to the side of the heating machine 1, a handle 5 fixedly connected to the top of the heating machine 1, and a limit device 2 provided on the side of the heating machine 1.
[0029] The working principle of the high-frequency induction heating machine 1 is based on the electromagnetic induction effect. A high-frequency current generates an alternating magnetic field in the induction coil, causing eddy currents to form inside the metal workpiece, which then rapidly heats up due to resistance. Its core processes include high-frequency current generation, electromagnetic induction, eddy current heat generation, and the skin effect.
[0030] Working principle and core components
[0031] High-frequency current generation
[0032] The equipment converts ordinary power (such as 220V / 50Hz) into high-frequency (usually several kilohertz to several megahertz), high-voltage, low-current AC power, which is then further adjusted to low-voltage, high-current power by a transformer to meet the needs of induction heating.
[0033] Electromagnetic induction and eddy current effect
[0034] When a high-frequency current is passed through the induction coil, a high-intensity alternating magnetic field is generated.
[0035] When a metal workpiece is placed in a magnetic field, closed eddy currents (induced currents) are formed inside it due to electromagnetic induction.
[0036] According to Joule's law (Q = I²Rt), eddy currents are converted into heat energy under the action of metal resistance, thus achieving rapid heating.
[0037] Skin effect and heating control
[0038] The skin effect of high-frequency current causes eddy currents to concentrate on the metal surface, resulting in preferential heating of the surface layer. The heating depth can be controlled by adjusting the current frequency: the higher the frequency, the shallower the heating layer, which is suitable for surface heat treatment (such as quenching); the lower the frequency, the greater the heating depth, which is suitable for overall heating (such as melting).
[0039] Key features and auxiliary mechanisms
[0040] Proximity effect: When a high-frequency current in opposite directions is passed through an adjacent conductor, the interaction of magnetic fields can improve heating efficiency.
[0041] Non-contact heating: No direct contact with the heat source is required, reducing pollution and energy loss.
[0042] Precise control: By adjusting the frequency, power and heating time, the temperature distribution and heating speed can be precisely controlled, making it suitable for uniform heating of workpieces with complex shapes.
[0043] Reference Figure 2 The limiting device 2 includes a rectangular rod 21 fixedly connected to the side of the heating machine 1. A limiting ring 22 is fixedly connected to the side of the rectangular rod 21. A brush 24, which is made of iron wire, is fixedly connected to the inner wall of the limiting ring 22. A scraper ring 23, which is made of rubber, is fixedly connected to one end of the limiting ring 22. A through groove 25 is opened on the inner wall of the limiting ring 22. A rectangular plate 26 is fixedly connected to the bottom of the limiting ring 22. A collection frame 27 is fixedly connected to the side of the rectangular plate 26. A locking rod 28 is inserted into the side of the collection frame 27. The locking rod 28 is inserted into the interior of the collection frame 27.
[0044] Working principle: When the steel wire needs to be limited and cleaned, the steel wire is passed through the limiting ring 22 so that the steel wire will not come into contact with the spiral heating wire 6 when heated. Under the action of the brush 24, the impurities on the surface of the steel wire are cleaned and scraped off, thereby achieving the cleaning effect. Under the action of the scraper ring 23, the impurities on the surface of the steel wire are cleaned off, thereby cleaning the steel wire. The collection frame 27 is fixed to the surface of the rectangular plate 26 by the clamp 28, so that the cleaned impurities fall into the interior of the collection frame 27 through the through groove 25, thereby achieving the function of collecting impurities from the steel wire and thus achieving the limiting function.

The baffle 35 is provided at the bottom of the adjustment component 38.
[0046] The working principle is as follows: When it is necessary to cool the heated steel wire, the heated steel wire is passed through the ring 31. The water pump is started so that the cooling water inside the water tank 33 enters the interior of the groove 32 through the water pipe 34. When the cooling water inside the groove 32 enters the interior of the water tank 33 through the connecting pipe, the cooling water can be circulated. When the heated cooling water flows back into the interior of the water tank 33, the cooling water flowing back into the water tank 33 can be cooled by the action of the condenser pipe 36. When it is necessary to adjust the flow rate of the water inlet pipe 37, the threaded rod 382 is turned by hand, so that the extrusion plate 383 moves on the surface of the slide rod 381, thereby extruding the water inlet pipe 37 and thus achieving the phenomenon of adjusting the flow rate. Under the action of the baffle 35, the adjusting component 38 can be restricted on the surface of the water inlet pipe 37, thereby achieving the cooling effect.
