Description

Technical Field

[0001] This utility model relates to the field of electromagnetic wire drawing technology, specifically to an electromagnetic wire drawing device. Background Technology

[0002] Electromagnetic wire drawing is a key process in the manufacture of electromagnetic wire. It involves stretching a metal conductor to achieve the desired diameter while maintaining surface insulation. During the drawing process, the metal rod is continuously stretched into a thin wire through a die. Annealing and lubrication processes ensure the conductor's ductility and the integrity of the insulation layer. This process directly affects the conductivity, heat resistance, and mechanical strength of the electromagnetic wire. In the existing technology, authorized publication number CN 221289047... U proposes an electromagnetic wire drawing device, including a base, a support seat fixedly connected to the top outer wall of the base, and a screw rotatably connected to one side outer wall of the support seat. A heating mechanism is provided on the outer wall of the screw. A servo motor is fixedly connected to one side outer wall of the support seat, and the output shaft of the servo motor is fixedly connected to the screw. A mounting plate is fixedly connected to one side outer wall of the base, and one end of the screw is rotatably connected to the mounting plate. A common sliding rod is fixedly connected between the mounting plate and the support seat. Although this device can draw electromagnetic wire, directly heating the electromagnetic wire through a heating wire during the drawing process can easily lead to inaccurate temperature readings, affecting the drawing quality. Even if some drawing devices use a heat-conducting medium to heat the electromagnetic wire, ensuring accurate heating temperature, the temperature of the heat-conducting medium gradually decreases as heating progresses, and the temperature difference between the heat-conducting medium and the electromagnetic wire can easily become too small, affecting heating efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electromagnetic wire drawing device that, while using a heat-conducting medium to ensure accurate heating temperature, avoids the impact of an excessively small temperature difference between the heat-conducting medium and the electromagnetic wire on heating efficiency, making the heating of the electromagnetic wire drawing device faster and more accurate, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic wire drawing device, including a worktable, a wire drawing mold provided in the middle of the upper surface of the worktable, traction wheels rotatably connected to the conveyor frames at both ends of the upper surface of the worktable, and a heating mechanism; Heating mechanism: It includes a heating shell, a heating mold, and heating channels. The heating shell is located on the left end of the upper surface of the workbench. The heating mold is installed in the mounting hole at the upper end of the heating shell. Heating channels are provided inside the heating mold. The length of the heating channels decreases stepwise from left to right. The heat-conducting oil flows in the heating channels with the stepwise decreasing length to heat the electromagnetic wire. After the temperature difference between the heat-conducting oil and the electromagnetic wire decreases to a certain range, the heat-conducting oil is guided away in time. While using the heat-conducting medium to ensure accurate heating temperature, it avoids the impact of too small a temperature difference between the heat-conducting medium and the electromagnetic wire on the heating efficiency, making the heating of the electromagnetic wire drawing device faster and more accurate.

[0005] Furthermore, a PLC controller is provided at the left end of the workbench. The input terminal of the PLC controller is electrically connected to an external power supply to control the start and stop of the entire device.

[0006] Furthermore, the heating mechanism also includes an outlet pipe, a manifold, a diverter, a circulation pump, and a connecting pipe. The manifold and diverter are both located at the lower end of the heating shell. The outlet pipes are respectively located at the outlet of the heating mold, and the lower ends of the outlet pipes are connected to the manifold. The connecting pipes are respectively located at the inlet of the heating mold, and the lower ends of the connecting pipes are connected to the diverter. A circulation pump is connected in series between the diverter and the manifold. The input end of the circulation pump is electrically connected to the output end of the PLC controller to provide power and space for the circulation of the heat transfer oil.

[0007] Furthermore, the heating mechanism also includes heating cylinders, which are connected in series in the middle of the connecting pipe to heat the heat transfer oil.

[0008] Furthermore, each of the mounting grooves on the outer arc surface of the connecting pipe is equipped with a temperature sensor. The temperature sensor is installed in conjunction with the heating cylinder, and the output end of the temperature sensor is electrically connected to the input end of the PLC controller to detect the temperature of the heat transfer oil.

[0009] Furthermore, all heating channels are spiral channels, which reduces the footprint while extending the heat exchange time between the heat transfer oil and the electromagnetic wire.

[0010] Furthermore, a heat insulation pad is provided at the upper inner end of the heating shell. The heat insulation pad is movably sleeved on the outer arc surface of the heating mold to prevent heat from dissipating outward.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This electromagnetic wire drawing device has the following advantages: The electromagnetic wire is heated by the flow of heat-conducting oil in a heating channel with a stepped decreasing length. The heat-conducting oil is guided away in time after the temperature difference between the heat-conducting oil and the electromagnetic wire decreases to a certain range. While ensuring accurate heating temperature by using the heat-conducting medium, the heating efficiency is avoided if the temperature difference between the heat-conducting medium and the electromagnetic wire is too small, making the heating of the electromagnetic wire drawing device faster and more accurate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: an electromagnetic wire drawing device, including a workbench 1, with a drawing die 2 in the middle of the upper surface of the workbench 1. After the electromagnetic wire passes through the inside of the drawing die 2, it is drawn into wire under the extrusion of the drawing die 2. Traction wheels 3 are rotatably connected to the conveyor frames at both ends of the upper surface of the workbench 1. The shafts of the traction wheels 3 are connected to the output shaft of the conveyor motor inside the workbench 1 through a transmission component, providing power for the rotation of the traction wheels 3. The electromagnetic wire is conveyed by the rotation of the traction wheels 3. A PLC controller 6 is provided at the left end of the workbench 1. The input terminal of the PLC controller 6 is electrically connected to an external power source to control the start and stop of the entire device. The input terminal of the conveyor motor inside the workbench 1 is electrically connected to the output terminal of the PLC controller 6. The device also includes a heating mechanism 4. Heating mechanism 4 includes a heating shell 41, a heating mold 42, and heating channels 43. The heating shell 41 is located on the left end of the upper surface of the worktable 1. The heating mold 42 is installed in the mounting hole at the upper end of the heating shell 41. Heating channels 43 are respectively provided inside the heating mold 42. The length of the heating channels 43 decreases stepwise from left to right, and the lateral length of the heating channels 43 also decreases stepwise from left to right. When the heat transfer oil flows inside the heating channels 43, the heat in the heat transfer oil is transferred to the electromagnetic wire inside the heating mold 42 under the heat conduction of the heating mold 42. As the heat transfer oil flows to the right in the heating channels 43, the temperature of the heat transfer oil gradually decreases. Meanwhile, the higher the temperature at the point where heat exchange occurs between the electromagnetic wire and the heat transfer oil, the smaller the temperature difference between them gradually becomes. The heating channel 43 decreases in a stepwise manner from left to right, ensuring the heat transfer oil leaves the heating mold 42 promptly after its temperature drops to a certain range. This prevents excessive temperature difference between the heat transfer oil and the electromagnetic wire, guaranteeing efficient heat transfer. The heating mechanism 4 also includes an outlet pipe 44, a manifold 45, a distribution tank 46, a circulation pump 47, and a connecting pipe 49. The manifold 45 and distribution tank 46 are both located at the lower end of the heating shell 41. The outlet pipe 44 is located at the outlet of the heating mold 42, and its lower end connects to the manifold 45. The connecting pipes 49 are respectively set at the liquid inlet of the heating mold 42. The lower end of each connecting pipe 49 is connected to the distribution tank 46. A circulation pump 47 is connected in series between the distribution tank 46 and the manifold tank 45. The input end of the circulation pump 47 is electrically connected to the output end of the PLC controller 6. When the circulation pump 47 is started, the heat transfer oil circulates sequentially between the distribution tank 46, the heating channel 43 and the manifold tank 45. The heating mechanism 4 also includes a heating cylinder 48, which is connected in series in the middle of the connecting pipes 49. Each heating cylinder 48 is equipped with an electric heating tube. The input end of each electric heating tube is electrically connected to the output end of the PLC controller 6. The heat generated by the electric heating tube is used for heat transfer. The oil is heated, and temperature sensors 5 are installed in the mounting grooves on the outer arc surface of the connecting pipe 49. The temperature sensors 5 are installed in conjunction with the heating cylinder 48. The output end of the temperature sensor 5 is electrically connected to the input end of the PLC controller 6 to detect the temperature of the heat transfer oil flowing out of the heating cylinder 48, so as to facilitate accurate control of the temperature of the heat transfer oil. The heating flow channels 43 are all spiral flow channels, which reduces the footprint and extends the flow path of the heat transfer oil. The upper part of the interior of the heating shell 41 is provided with a heat insulation pad 7, which is movably sleeved on the outer arc surface of the heating mold 42. The heat insulation pad 7 can be a silicone heat insulation pad to prevent the heat inside the heating mold 42 from dissipating outward and reduce heat loss.

[0016] The working principle of the electromagnetic wire drawing device provided by this utility model is as follows: During use, the electromagnetic wire is passed sequentially from left to right between the two traction wheels 3 on the left, inside the heating mold 42, inside the drawing mold 2, and between the two traction wheels 3 on the right. The rotation of the traction wheels 3 provides power for conveying the electromagnetic wire, pulling it through the drawing mold 2. Under the pressure of the drawing mold 2, the electromagnetic wire is drawn into wire. During the drawing process, the circulating pump 47 is started by the PLC controller 6, causing the heat transfer oil to circulate sequentially between the distribution tank 46, the heating cylinder 48, the heating channel 43, and the manifold 45. When the heat transfer oil enters the heating cylinder 48 through the connecting pipe 49, the heating element inside the heating cylinder 48 heats the oil. The temperature sensor 5 monitors the flow from the heating cylinder... The temperature of the heat transfer oil flowing out of the heating cylinder 48 is detected. Based on the detection result, the PLC controller 6 controls the heating power of the heating tube of the heating cylinder 48, thereby achieving accurate control of the temperature of the heat transfer oil. When the heat transfer oil flows inside the heating channel 43, under the heat conduction of the heating mold 42, the heat in the heat transfer oil is transferred to the electromagnetic wire inside the heating mold 42. As the heat transfer oil flows to the right in the heating channel 43, the temperature of the heat transfer oil gradually decreases. At the same time, the temperature at the point where the electromagnetic wire exchanges heat with the heat transfer oil is higher, and the temperature difference between the heat transfer oil and the electromagnetic wire gradually decreases. The heating channel 43 decreases in a stepwise manner from left to right, so that the temperature of the heat transfer oil leaves the heating mold 42 in time after it decreases to a certain range, preventing the temperature difference between the heat transfer oil and the electromagnetic wire from being too large and ensuring the efficiency of heat conduction.

[0017] It is worth noting that the PLC controller 6 disclosed in the above embodiments can be an NX7 model PLC controller, and the circulating pump 47 and temperature sensor 5 can be freely configured according to the actual application scenario. The circulating pump 47 can be an RY50-32-200 model hot oil pump, and the temperature sensor 5 can be a 10TP583T model temperature sensor. The PLC controller 6 controls the operation of the circulating pump 47 and the temperature sensor 5 using methods commonly used in the prior art.

[0018] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
