Description

Technical Field

[0001] This invention relates to the technical field of wire pre-cleaning devices for induction heating equipment, and particularly to the technical field of wire pre-cleaning devices for induction heating equipment. Background Technology

[0002] Electromagnetic induction heating, or simply induction heating, is a method of heating conductive materials such as metals. It is mainly used for metal hot working, heat treatment, welding, and melting. As the name suggests, induction heating uses electromagnetic induction to generate an internal current in the material being heated, relying on the energy of these eddy currents to achieve the heating purpose. The basic components of an induction heating system include an induction coil, an AC power supply, and a workpiece. Depending on the object being heated, the coil can be made into different shapes. The coil is connected to the power supply, which provides alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field through the workpiece, which induces eddy currents in the workpiece, thus heating it. Induction surface hardening utilizes the principle of electromagnetic induction to generate a high-density induced current on the surface of the workpiece, rapidly heating it to the austenitic state, followed by rapid cooling to obtain a martensitic structure. When an alternating current of a certain frequency passes through the induction coil, an alternating magnetic field with the same frequency as the current change will be generated inside and outside it. When a metal workpiece is placed inside the induction coil, under the influence of the magnetic field, an induced current with the same frequency but opposite direction to the induction coil will be generated inside the workpiece. Because the induced current forms a closed loop along the surface of the workpiece, it is usually called an eddy current. This eddy current converts electrical energy into heat energy, rapidly heating the surface of the workpiece. The eddy currents are mainly distributed on the workpiece surface, with almost no current flowing inside; this phenomenon is called the surface effect or skin effect. Induction heating utilizes the skin effect, relying on the thermal effect of the electric current to rapidly heat the workpiece surface to the quenching temperature. The induction coil is made of copper tubing and contains cooling water. When the workpiece surface is heated to a certain temperature within the induction coil, water is immediately sprayed for cooling, causing the surface layer to acquire a martensitic structure.

[0003] When existing bars are heated by induction heating equipment, impurities carried on the outer wall of the bars also enter the induction heating tunnel along with the bars. Over time, these impurities accumulate in the induction heating tunnel, which affects the normal heating effect of the induction heating equipment on the bars and fails to meet people's needs.

[0004] To address the aforementioned issues, application number CN202021715356.0 discloses a pre-cleaning device for rods used in induction heating equipment. This device cleans the rods by grinding with a tubular abrasive layer. While it can clean the rods to some extent, it still has some drawbacks: the grinding holes in the abrasive layer have a fixed shape, limiting its application to rods of the same size. Furthermore, the rods are prone to slight displacement during transportation, which can easily scratch them. Additionally, the device can only clean rods of a fixed size, resulting in a narrow application range. Moreover, grinding the wire surface does not effectively remove the protective oil from the rod surface. Although the protective oil can be evaporated by the induction heating device, it produces oil fumes, which is detrimental to the cleanliness of the indoor environment.

[0005] Therefore, in order to solve the above problems, it is necessary to propose a wire pre-cleaning device for induction heating equipment. Summary of the Invention

[0027] Working process of this invention:

[0028] The wire pre-cleaning device for induction heating equipment of the present invention comprises the following steps during operation:

[0029] 1) Pass one end of the wire sequentially between the first electric roller 21 and the second electric roller 22, the feed hole 11, between the first horizontal electric brush roller 31 and the second horizontal electric brush roller 32, between the two vertical electric brush rollers 41, the discharge hole 12, the inner hole of the second metal annular tube 76, the inner hole of the induction heating coil 6, the inner hole of the first metal annular tube 74, and between the third electric roller 82 and the fourth electric roller 83;

[0030] 2) Open the box door 102 and inject cleaning solution into the cleaning tank 10;

[0031] 3) Run the spray system 7, start the pump body 71, and the cleaning fluid passes through the pump body 71, the metal inlet pipe 72, the basket filter 73 in the middle of the metal inlet pipe 72, the first metal annular pipe 74, the metal connecting pipe 75, the second metal annular pipe 76, the metal outlet pipe 77, and the nozzle 78 in sequence. The nozzle 78 sprays the cleaning fluid onto the wire.

[0032] 4) Based on the wire size and specifications, operate the first lifting device 35 and the linear displacement device 44 to appropriately adjust the distance between the first horizontal electric brush roller 31 and the second horizontal electric brush roller 32, and the distance between the two vertical electric brush rollers 41, so that the brush rollers are adapted to the wire.

[0033] 5) Start the first horizontal electric brush roller 31, the second horizontal electric brush roller 32, and the two vertical electric brush rollers 41, so that the brush rollers rotate in conjunction with the cleaning liquid to brush the surface of the wire.

[0034] 6) The first electric roller 21 and the second electric roller 22, together with the third electric roller 82 and the fourth electric roller 83, transport the wire from left to right, thereby cleaning the wire during the rightward movement.

[0035] 7) When the wire enters the inner hole of the induction heating coil 6, the induction heating coil 6 heats the wire and dries the cleaning solution on the surface of the wire. Since the first metal ring tube 74 and the second metal ring tube 76 are both made of metal, the induction heating coil 6 will also heat the first metal ring tube 74 and the second metal ring tube 76, causing the cleaning solution to heat up. Hot water is more conducive to cleaning the oil stains on the surface of the wire.

[0036] This invention features a simple structure and reasonable design, enabling pre-cleaning of wires of various sizes and shapes. It has a wide range of applications, reduces oil fumes generated during heat treatment, and promotes cleaner workshop air.

This invention is adaptable to various sizes of wires, making its application range wider.

By providing a first metal annular tube 74 and a second metal annular tube 76 at the left and right ends of the inner hole of the induction heating coil 6, since the first metal annular tube 74 and the second metal annular tube 76 are both made of metal, the induction heating coil 6 will also heat the first metal annular tube 74 and the second metal annular tube 76, thereby raising the temperature of the cleaning solution. Hot water is more conducive to cleaning the oil stains on the surface of the wire.

[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
