[0002] Ultrasonic induction heating equipment is widely used in heating, heat forging, quenching, welding and annealing of various metal workpieces. Its working principle is based on the law of electromagnetic induction. When a metal workpiece is placed in a changing magnetic field, eddy currents will be generated inside the workpiece. According to Joule's law, the eddy currents generate heat under the action of the workpiece's own resistance, thereby rapidly heating the metal workpiece to reach the temperature conditions required by the corresponding processing technology.

[0003] However, traditional ultrasonic induction heating equipment can only produce steel wire of the same diameter at a time, and the heat obtained by the steel wires at different positions inside the heating coil is different. At the same time, the linear speed of each steel wire is also slightly different, which leads to a certain degree of difference in the temperature of each steel wire. As a result, there will be differences in the steel wires produced, and the quality of the steel wires cannot be completely consistent. Summary of the invention

DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] See also Figure 1 ~ to 4, the present invention provides a single-filament single-control ultrasonic induction heating device, comprising an incoming line detection terminal 1, a heating furnace body 2, an outlet line roller 4 and an insulation furnace body 3, the incoming line detection terminal 1 is arranged at one end of the heating furnace body 2, the heating furnace body 2 is arranged at one end of the insulation furnace body 3, and the outlet line roller 4 is arranged at the end of the insulation furnace body 3 away from the heating furnace body 2.

[0027] In this embodiment, the design can detect the actual speed of each steel wire in real time, so as to adjust the heating power in real time according to the actual speed, so that the steel wires of different diameters and speeds can reach the predetermined temperature, which can better control the quality of the produced steel wires, improve the yield rate, and then improve the production efficiency. In addition, the equipment can also produce steel wires of different specifications and speeds at the same time, which greatly improves the flexibility of production. In this way, the traditional ultrasonic induction heating equipment can only produce steel wires of the same diameter at a time, and the heat obtained by the steel wires at different positions inside the heating coil is different. At the same time, the linear speed of each steel wire is also slightly different, which leads to a certain degree of difference in the temperature of each steel wire. In this way, there will be differences in the steel wires produced, and the technical problem that the quality of the steel wires cannot be completely consistent.

[0028] In this embodiment, the interior of the insulation furnace body 3 is made of high-temperature resistant corundum material, and the outside is made of chlorate heavy cement. Its function is to place the heated steel wire in a closed environment to keep it at a high temperature for a period of time. After the steel wire passes through the insulation furnace body, the temperature will not drop rapidly.

[0029] Furthermore, a control console 5 is provided at one side of the incoming line detection terminal 1 , and the control console 5 is connected to the incoming line detection terminal 1 by a wire.

[0030] In this embodiment, the diameter and temperature of each steel wire can be set through the console 5. The console 5 can receive the signal detected and fed back by the incoming line detection terminal 1, and automatically set the voltage, current and frequency required for each steel wire, thereby ensuring that each steel wire can reach the required temperature.

[0031] Furthermore, a heating power source 6 is provided on one side of the heating furnace body 2, and the heating power source 6 is connected to the heating furnace body 2 by a wire.

[0032] In this embodiment, the heating furnace body 2 is provided with energy by the heating power source 6 .

[0033] Furthermore, a heat preservation power supply 7 is provided on one side of the heat preservation furnace body 3, and the heat preservation power supply 7 is connected to the heat preservation power supply 7 by wires.

[0034] In this embodiment, the heat preservation furnace body 3 is provided with energy by the heat preservation power supply 7 .

[0035] Furthermore, cooling channels are provided in the heating furnace body 2, the heat-insulating furnace body 3, the heating electric source 6 and the heat-insulating power source 7, and the cooling channels between the heating furnace body 2, the heat-insulating furnace body 3, the heating electric source 6 and the heat-insulating power source 7 are interconnected.

[0036] Furthermore, a circulating cooling mechanism is connected to the cooling channel, and the circulating cooling mechanism consists of a water tank 8, a plate heat exchanger 9 and a circulating water pump 10. The water tank 8 is provided with a temperature probe and a liquid level detector. A three-way regulating valve 11 is provided at the cooling water inlet of the plate heat exchanger 9, and the inlet and outlet of the cooling channel are respectively connected to the other two valve ports of the three-way regulating valve 11. The plate heat exchanger 9 is connected to the outside of the water tank 8, and the circulating water pump 10 is arranged in the water tank 8.

[0037] In this embodiment, the temperature and liquid level in the water tank 8 are detected in real time by the temperature measuring probe and the liquid level detector. The circulating water pump 10 pumps the cooling water in the water tank 8 to the cooling channel between the heating furnace body 2, the insulation furnace body 3, the heating power source 6 and the insulation power source 7 through a pipeline to cool the equipment. The water temperature rises after cooling, and then enters the plate heat exchanger 9 for heat exchange and cooling, and then returns to the water tank 8 to complete the cycle. The plate heat exchanger 9 is externally connected to factory cooling water to heat exchange and cool the pure water. The three-way regulating valve 11 can automatically adjust the amount of factory cooling water entering the plate heat exchanger 9 according to the temperature feedback inside the water tank 8, thereby realizing the pure water temperature control in the water tank 8.

[0038] Furthermore, the heating power source 6 and the heat preservation power source 7 are also connected to the console 5 by wires respectively.

[0039] In this embodiment, the heating power source 6 and the insulation power source 7 will provide corresponding voltage, current and frequency according to the control signal given by the control console 5, so that the heating furnace body 2 and the insulation furnace body 3 can induction heat the steel wire.

[0040] Furthermore, the incoming line detection end includes a plurality of movable sleeves 14 and a bracket 20, a detection switch 15 is provided at one end of the movable sleeve 14, an encoder 16 is provided at the other end of the movable sleeve 14, a wire wheel 17 is provided on the encoder 16, a support rod 18 and two wire guide rollers 19 are provided on the bracket 20, and the plurality of movable sleeves 14 are rotatably connected to the support rod 18 and sleeved on the support rod 18, and the detection switch 15 and the encoder 16 are connected to the control console through wires, and the bracket 20 is located at one end of the heating furnace body.

[0041] In this embodiment, when the continuous steel wire passes through the wire wheel 17, the movable sleeve 14 is in an inclined state. There will be a certain pulling force when the steel wire is running, so that the steel wire is in a straight state, so that the wire wheel 17 can always be on the steel wire, and then the speed of the steel wire is read by the encoder 16. At this time, the detection switch 15 is in the detection range, then it can be determined that there is a steel wire. When there is no steel wire, the movable sleeve 14 will drive the wire wheel 17 to remain in a vertical state under the action of gravity. At this time, the detection switch 15 detects that the wire wheel 17 is not in the detection range, and it can be prompted that the wire is missing.
