Description

Technical Field

[0002] The high-frequency heating device for wires plays an important role in industrial production, which mainly involves the principle of electromagnetic induction heating, the advantages of high-frequency heating technology, and the actual requirements in the field of wire processing.

[0003] Electromagnetic induction heating is the core principle of the high-frequency heating device for wires. When a high-frequency current passes through a coil, an alternating magnetic field will be generated around it. When a wire (or other conductive material) enters this magnetic field, an induced current (i.e., eddy current) will be generated inside it. When these eddy currents flow inside the wire, heat will be generated due to the resistance of the material, thus heating the wire. This heating method has the advantages of fast heating speed, uniform heating, and high energy utilization rate.

[0004] The high-frequency heating technology has significant advantages compared with traditional heating methods. For example, high-frequency heating can achieve rapid heating, which is very important for heat treatment processes such as quenching and tempering of wires. In addition, high-frequency heating can also achieve local heating, which is of great significance for improving the performance of wires and the quality of products.

However, due to the diversity of wires, the debugging process may become quite complex and time-consuming.

[0007] Uneven heating: The heating effect of the high-frequency heating device may be affected by the shape, size, and material properties of the wire. In some cases, uneven heating may occur, resulting in local overheating or underheating of the wire, thus affecting the product quality.

[0008] Efficiency issues: During the high-frequency heating process, the heating efficiency is affected by various factors, and environmental temperature, humidity, etc. may also have a certain impact on the heating efficiency.

[0009] Electromagnetic radiation: The high-frequency heating device will generate electromagnetic radiation during operation, which may have a certain impact on the health of operators. Therefore, appropriate protective measures need to be taken to reduce the impact of electromagnetic radiation on personnel. Content of the Utility Model

[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0033] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention relates to a high-frequency heating device for steel wires, including a housing 1. A high-frequency power supply 2, a transformer 3, an auxiliary heating component 5, and a temperature measurement unit 6 are installed inside the housing 1. The high-frequency power supply 2 is located on one side of the transformer 3. A connection component 4 is provided on the side of the transformer 3 away from the high-frequency power supply 2.

The telescopic movement of the telescopic rod 8 drives the sliding component 702 to slide on the inner heating coil 703, driving the inner heating coil 703 to expand or contract; wherein, the external connection wire of the inner heating coil 703 is a flexible wire to ensure normal operation after the inner heating coil 703 expands and contracts. The auxiliary heating component 5 is used to provide an additional heating effect to ensure uniform heating of the steel wire 9.

The support member 10 can be replaced with a shape according to needs and mainly supports the outer heating coil 701.

[0035] As Figure 4 shown, the connection component 4 includes a partition plate 401, the partition plate 401 is fixedly connected to the inside of the housing 1, the partition plate 401 is located on the side of the transformer 3 away from the high-frequency power supply 2, a fixing plate 402 is installed on the side of the partition plate 401 away from the transformer 3, a fixing rod 403 is detachably connected to the fixing plate 402, one end of the fixing rod 403 away from the fixing plate 402 is detachably connected to a fixing plate 404, and the side of the fixing plate 404 away from the transformer 3 is respectively connected to the outer heating coil 701 and the inner heating coil 703.

[0036] Among them, the partition plate 401 is located between the transformer 3 and the induction heating component 7 and is used to isolate the high-frequency power supply 2 and the induction heating component 7 to reduce electromagnetic interference. A fixing plate 402 is installed on the side of the partition plate 401 away from the transformer 3, the fixing rod 403 is detachably connected to the fixing plate 402 by a threaded connection method, the other end of the fixing rod 403 is also detachably connected to the fixing plate 404 by a threaded connection method, and the induction heating component 7 is installed on the fixing plate 404, which is convenient for disassembly and maintenance.

[0037] Preferably, the partition plate 401 divides the housing 1 into a heating area and a power supply area; the high-frequency power supply 2 and the transformer 3 are installed in the power supply area; the auxiliary heating component 5, the temperature measurement unit 6, the telescopic rod 8 and the induction heating component 7 are installed in the heating area.

[0038] The housing 1 is divided into two regions, isolating the air circulation in the heating zone and reducing the temperature loss.

[0039] As Figure 6 , Figure 7 and Figure 8 shown, the sliding assembly 702 includes a connecting member 7022, the connecting member 7022 is fixedly connected to the telescopic rod 8, a fixing member 7023 is fixedly connected to a surface of the connecting member 7022 away from the telescopic rod 8, a movable rail 7026 is fixedly connected to the middle of the long inclined surface of the fixing member 7023, the movable rail 7026 is slidably connected to a fixed rail 7025 in a matching manner, both ends of the fixed rail 7025 are detachably connected with limiting blocks 7027, a sliding member 7024 is fixedly connected to a side of the fixed rail 7025 away from the movable rail 7026, the sliding member 7024 is fixedly connected with a fixing ring 7021, and the fixing ring 7021 is slidably connected to the inner heating coil 703.

[0040] Among them, at one end of the telescopic rod 8 away from the housing 1, a plurality of sliding assemblies 702 are fixedly connected at intervals up and down. Each sliding assembly 702 includes a connecting member 7022, the connecting member 7022 is fixedly connected to the telescopic rod 8, a fixing member 7023 is fixedly connected to one end of the connecting member 7022 away from the telescopic rod 8, and a movable rail 7026 is fixedly connected to the fixing member 7023. The movable rail 7026 is slidably connected to a fixed rail 7025 in a matching manner, both ends of the fixed rail 7025 are connected with limiting blocks 7027 by bolts to prevent the movable rail 7026 from slipping off. A sliding member 7024 is fixedly connected to a side of the fixed rail 7025 away from the movable rail 7026, a fixing ring 7021 is fixedly connected to the sliding member 7024, the fixing ring 7021 is sleeved on the inner heating coil 703 and is slidably connected thereto. In this way, by adjusting the length of the telescopic rod 8, the position of the sliding assembly 702 on the inner heating coil 703 can be adjusted, and further the distance between the inner heating coil 703 and the steel wire 9 can be changed, and the steel wire 9 to be heated with different diameter specifications can be replaced as needed; fine adjustment of the heating temperature can also be achieved; by driving the sliding assembly 702 to slide on the inner heating coil 703 through telescopic movement, the expansion or contraction of the inner heating coil 703 can be realized to adapt to steel wires 9 with different diameters. At the same time, the operator can independently adjust the position of the sliding assembly 702 according to the steel wires 9 with different diameters. Adjusting the position of the sliding assembly 702 is to adapt to steel wires 9 with different diameters, so as to ensure the uniformity and efficiency of heating. Among them, the fixing ring 7021 is sleeved on the inner heating coil 703.

[0041] As Figure 5As shown, the auxiliary heating component 5 includes a hot air blower 501, which is detachably connected to the inner bottom surface of the housing 1. The air outlet of the hot air blower 501 is connected to an air supply duct 502, and one side of the air supply duct 502 away from the hot air blower 501 is connected to an air supply box 503. The air supply box 503 is detachably connected to the inner bottom surface of the housing 1. A air supply port 504 is formed in the middle of one side of the air supply box 503 away from the air supply duct 502, and a plurality of air supply holes 505 are formed around the air supply port 504.

[0042] By reasonably designing the positions, quantities, and sizes of the air supply port 504 and the air supply holes 505, as well as the power and air supply speed of the hot air blower 501, and working in cooperation with the induction heating component 7, uniform heating of the steel wire 9 is achieved. The air supply port 504 is arranged on one side of the steel wire 9 to ensure that the hot air blows directly onto the steel wire 9. The layout of the air supply holes 505 can be adjusted according to actual needs to supplement the air supply effect of the air supply port 504, enhance the air flow disturbance around the steel wire 9, and thus improve the heating uniformity.

[0043] In order to improve the heating uniformity and efficiency as much as possible, by selecting a suitable hot air blower 501, it is ensured that its power and air volume can meet the heating requirements and can work stably.

[0044] When the diameter specifications of the steel wire 9 to be heated are different, the power and air volume provided by the hot air blower 501 will also change accordingly.

[0045] Optionally, the temperature measurement unit 6 is an MLX90614 infrared temperature sensor.

[0046] The MLX90614 infrared temperature sensor adopts a non-contact measurement method and will not interfere with the object to be measured. In addition, the MLX90614 infrared temperature sensor also has the characteristics of fast response and good stability, can real-time monitor the temperature change of the steel wire 9 to be heated, and then accurately control the heating temperature by controlling the power of the high-frequency power supply 2 and the power of the auxiliary heating component 5.

[0047] Optionally, the sliding components 702 are symmetrically arranged at intervals on the movable end of the telescopic rod 8.

[0048] By symmetrically arranging the sliding components 702 at intervals on the movable end of the telescopic rod 8, the stability of the inner heating coil 703 expanding and contracting as the telescopic rod 8 expands and contracts is ensured.

[0049] To ensure the safety of the operator, the housing 1 is an electromagnetic shielding housing.

[0050] The electromagnetic shielding design effectively isolates the electromagnetic radiation generated by the internal high-frequency power supply 2, can effectively reduce the harm of the steel wire high-frequency heating device to the operator, and improve the safety and reliability of the operation process. Embodiment

[0051] When placing the steel wire 9 to be heated, use the steel wire clamping device to place it between the inner heating coil 703 and the outer heating coil 701, while avoiding the external connecting wires of the inner heating coil 703, and ensure that the steel wire 9 remains stationary.

[0052] When heating the steel wire 9 to be adapted to the inner heating coil 703 and the outer heating coil 701, the telescopic rod 8 does not move, and the telescopic rod 8 is currently in a state of being extended by half.

[0053] When heating the steel wire 9 in a space with a diameter larger than the space between the inner heating coil 703 and the outer heating coil 701, the telescopic rod 8 shortens to ensure that the space is sufficient to accommodate the steel wire 9 at this time. The shortening of the telescopic rod 8 drives the movement of the connecting member 7022, and then drives the movement of the fixed member 7023. At the same time, the sliding member 7024 moves inward, the inner heating coil 703 shrinks, and the space between the inner heating coil 703 and the outer heating coil 701 expands.

[0054] When heating the steel wire 9 in a space with a diameter smaller than the space between the inner heating coil 703 and the outer heating coil 701, the telescopic rod 8 extends to ensure that the space is sufficient to accommodate the steel wire 9 at this time. The extension of the telescopic rod 8 drives the movement of the connecting member 7022, and then drives the movement of the fixed member 7023. At the same time, the sliding member 7024 moves outward, the inner heating coil 703 expands, and the space between the inner heating coil 703 and the outer heating coil 701 decreases.

[0055] The control system regulates the power supply of the high-frequency power supply 2 by combining the internal algorithm of the high-frequency power supply 2 and the data of the temperature measuring unit 6, and adjusts the power of the auxiliary heating component 5 through the control system for normal heating, improving the uniformity of heating of the steel wire 9 to be heated.

[0056] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0057] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
