Description

Technical Field

[0001] This disclosure relates to the field of heating wire manufacturing technology, specifically to a device for winding tungsten-molybdenum spiral heating wire. Background Technology

[0002] Tungsten-molybdenum heating wires are used in various high-temperature furnaces, functioning as heating elements or as high-temperature resistant materials in high-temperature applications. Previously, spiral heating wires were manufactured to fit specific furnace specifications, resulting in pre-defined lengths for customer procurement and transportation.

[0003] With the upgrading of heating furnaces in the market, the demand for heating furnace capacity is higher, the specifications of heating furnaces are more numerous, the furnace body is larger, and the required heating wire length is also different. This has resulted in the fact that the previously fixed length spiral heating wire cannot be adapted to a variety of heating furnaces of different specifications. If each length of spiral heating wire is to be produced separately, production lines will need to be added, increasing investment costs. When faced with heating furnaces of different specifications, heating furnace manufacturers need to purchase, package, and transport spiral heating wires of different lengths separately, which greatly increases costs. Purchasing long heating wires and cutting them to correspond to the specifications of different heating furnaces is a feasible method. However, long heating wires often fail to wind due to their excessive length, causing the raw wire to become loose during the winding process.

[0004] Therefore, to solve the above problems, we propose a tungsten-molybdenum spiral heating wire winding device. Utility Model Content

The heating wire is integrally formed, without the need for separate processing of multiple sections, resulting in high processing quality. Moreover, customers can cut the heating wire according to the actual required length without the need for multiple sections to be connected sequentially, saving processes and costs.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1 Please refer to Figure 5 and Figure 6 A device for winding a tungsten-molybdenum spiral heating wire, comprising: The wire spool structure has a first axis and includes a main body 2 and a wire spool 3 that are coaxially rotated and sleeved. Raw material wire is wound on the outer wall of the wire spool 3. A damping generator 7 is provided between the main body 2 and the wire spool 3 to provide friction when the wire spool 3 and the main body 2 rotate relative to each other. Power unit 15, on which a rotating connector 16 is rotatably mounted, and the main body 2 is coaxially connected to the rotating connector 16; The core rod 1 extends along the first direction in the length direction, and the core rod 1 moves through the rotating connector 16 and the screw disc structure along the axial direction; The power unit is also equipped with a mobile platform extending along the first direction. A mobile table 17 is movably mounted on the mobile platform. The mobile table 17 has a clamping end for clamping the core rod 1 and the raw material wire. The first axis is parallel to the first direction. The rotating connector 16 is used to drive the wire spool structure to rotate around the first axis, while the moving table 17 drives the core rod 1 away from the rotating connector 16 in the first direction, so that the raw material wire is wound on the core rod 1 in a spiral form.

[0026] The first direction is Figure 6 Mid-horizontal direction.

[0027] Specifically, the rotary connector 16 is rotatably mounted on the power unit 15 around the first axis, with one end connected to the thread spool structure. Specifically, the rotary connector 16 and the main body 2 are coaxially fixedly connected to ensure that the thread spool structure and the rotary connector 16 are coaxial. The power unit 15 can be a lathe, and the rotary connector 16 can be the spindle of the lathe. The connection between the rotary connector 16 and the thread spool structure can be a chuck connection, which realizes the purpose of using local materials and facilitating production. The rotary connector 16 rotates at a uniform speed, and the moving table 17 translates at a uniform speed. One end of the raw material wire wound on the wire spool structure is taken out and wound onto the core rod 1. The core rod 1 is clamped by the clamping end, and the rotating connector 16 rotates, causing the wire spool structure to rotate. At the same time, the moving stage 17 clamps the core rod 1 and moves it away from the rotating connector 16 in the first direction. During this process, the raw material wire can be wound onto the core rod 1 in a spiral form, realizing the winding process of the heating wire. At the same time, since a damping generator 7 is set between the main body 2 and the wire spool 3, the main body 2 is driven to rotate by the rotating connector 16. The friction force provided by the damping generator 7 drives the wire spool 3 to rotate. The raw material wire is wound on the core rod 1, providing a pulling force on the wire spool 3 in the opposite direction of rotation. This makes the rotation speeds of the raw material wires different when they rotate relative to each other, ensuring that the raw material wires can be straightened, avoiding loosening of the raw material wires during the winding process, and improving the success rate of winding.

[0028] When the moving stage 17 moves to the end of the moving platform away from the rotating connector 16, the rotation of the rotating connector 16 stops, the clamping end releases the core rod 1, the moving stage 17 returns to the end of the moving platform close to the rotating connector 16, clamps the core rod 1 again, the rotating connector 16 rotates again, and the moving stage 17 clamps the core rod 1 and moves synchronously. This process is repeated, and theoretically, it is possible to achieve the infinitely long winding of the spiral heating wire.

[0029] like Figure 1 and Figure 2 As shown, the wire disc structure includes: Main body 2, which is a cylindrical structure and has a first axis; The silk disc 3 is a cylindrical structure that is coaxially and movably sleeved on the outer wall of the main body 2. A bushing 4 is provided between the outer wall of the main body 2 and the inner wall of the silk disc 3. Among them, bushing 4 is a self-lubricating bushing, used to provide lubrication between the outer wall of the main body 2 and the inner wall of the screw spool 3; When the main body 2 rotates, since there is a bushing 4 between the main body 2 and the wire disc 3, the rotation of the main body 2 will not affect the wire disc 3, so that the main body 2 and the wire disc 3 rotate relative to each other. The bushing 4 can be fixedly sleeved on the side wall of the main body 2 and slide relative to the wire disc 3; or it can be fixedly set on the inner wall of the wire disc 3 and slide relative to the main body 2.

[0030] Furthermore, a first mounting portion 5 extending radially is fixedly provided on the outer wall of the main body 2, and the wire spool 3 is located on the side of the first mounting portion 5 away from the rotating connector 16. A second mounting portion 6 extending radially is fixedly provided on the outer wall of the end of the wire spool 3 near the rotating connector 16. A damping generator 7 is provided between the first mounting part 5 and the second mounting part 6.

[0031] Specifically, both the first mounting part 5 and the second mounting part 6 can be ring-shaped structures, which are respectively fixedly sleeved on the outer walls of the main body 2 and the wire disc 3. Optionally, the first mounting part 5 and the second mounting part 6 are integral structures with the main body 2 and the wire disc 3. By providing a damping generator 7 between the first mounting part 5 and the second mounting part 6, a certain damping is provided between the first mounting part 5 and the second mounting part 6, preventing the main body 2 and the wire spool 3 from sliding freely. As the main body 2 rotates, the damping effect will cause the wire spool 3 to rotate. At the same time, during winding, the raw material wire is wound on the core rod 1, forming a pulling force on the wire spool 3 in the opposite direction of rotation, causing the main body 2 and the wire spool 3 to rotate at different speeds. The damping generator 7 can be fixedly connected to the first mounting part 5 or the second mounting part 6.

[0032] like Figure 3 and Figure 4 As shown, further, a mounting plate 8 is fixedly provided at the end of the wire disc 3 away from the rotating connector 16, and a guide nozzle 9 is coaxially provided on the side wall of the mounting plate 8 away from the rotating connector 16. The mounting plate 8 has a through hole, which is coaxial with the first axis and connected to the interior of the main body 2. A second through hole is provided through the guide nozzle 9. The second through hole and the first through hole are coaxial and connected. The core rod 1 passes through the first through hole and the second through hole. A third through hole is provided on the rotating connector 16 along the first axis.

[0033] Specifically, the core rod 1 movably passes through the first through hole, the second through hole and the third through hole, and both ends of the core rod 1 extend to both sides of the rotating connector 16.

[0034] Furthermore, a guide wheel assembly is provided on the mounting plate 8. The guide wheel assembly includes a first bracket 10, which is fixedly mounted on the side wall of the mounting plate 8. A first guide wheel 11 is rotatably mounted on the end of the first bracket 10 away from the mounting plate 8.

[0035] Furthermore, the guide wheel assembly also includes a second bracket 12, which is fixedly mounted on the side wall of the mounting plate 8 away from the rotating connector 16, and a second guide wheel 13 is rotatably mounted on the end of the second bracket 12 away from the mounting plate 8; Among them, the axis of the first guide wheel 11 is parallel to the second direction, and the second direction is... Figure 3 The second direction is perpendicular to the first direction, and the axis of the second guide wheel 13 is parallel to the third direction. A preset angle is formed between the third direction and the first direction, which makes it easier to wind the raw material wire onto the core rod 1. The preset angle is preferably 45°, and the opening direction of the preset angle is towards the core rod 1.

[0036] Both the first guide wheel 11 and the second guide wheel 13 have wire grooves on their circumferential sidewalls for accommodating raw material wires for winding. Specifically, such as Figure 7 As shown, by removing one end of the raw material wire wound on the wire spool 3, bringing it close to the first guide wheel 11, and winding it around the side of the first guide wheel 11 away from the mounting plate 8, then bringing the end close to the second guide wheel, winding it on the second guide wheel 13, and then connecting the end to the core rod 1, clamping the end and the core rod 1 together with the clamping end, and then, driven by the power device, the rotating connector 16 rotates, driving the wire spool structure to rotate, and under the action of the damping generator 7, the main body 2 and the wire spool 3 are prevented from rotating freely relative to each other. Through the damping effect provided by the damping generator 7, the raw material wire can be straightened. During the rotation of the rotating connector 16, the moving table 17 drives the core rod 1 and one end of the raw material wire connected to the core rod 1 to move, so that the raw material wire can be wound on the core rod 1 in a spiral form to complete the winding process of the heating wire.

[0037] Furthermore, a wire pressing seat 14 is provided on the side wall of the mounting plate 8 away from the rotating connector 16. The end of the wire pressing seat 14 near the second guide wheel 13 is a pressing end, which is used to apply pressure to the raw material wire extending from the second guide wheel 13, thereby guiding the raw material wire so that it can be wound on the core rod 1 and prevent it from becoming loose.

[0038] Furthermore, such as Figure 5 and Figure 6 As shown, a core rod damper 18 is provided on the side of the power unit 15 away from the rotating connector 16, which is used to straighten the core rod 1 when the moving platform 17 drives the core rod 1 to move. Specifically, during the process of the moving table 17 moving the core rod 1 and one end of the raw material wire connected to the core rod 1, the core rod damper 18 provides resistance, thereby ensuring that the core rod 1 is straight and avoiding bending of the core rod 1 which would affect the winding quality of the heating wire, thus improving the production quality.

[0039] Working principle: Before processing, the moving table 17 is close to the wire spool structure. The wire spool 3 is wound with raw material wire. When processing begins, one end of the raw material wire is removed and wound around the side of the first guide wheel 11 away from the mounting plate 8. Then it is brought close to the second guide wheel 13 and wound around the second guide wheel 13. When the end is led out from the second guide wheel 13, it passes through the clamping end and is abutted by the clamping end to ensure that it is pulled straight during winding and to prevent the raw material wire from loosening. Then it is brought close to the core rod 1 and the clamping end clamps one end of the raw material wire and the core rod 1. By starting the power unit, the rotating connector 16 drives the wire spool structure to rotate, while the moving platform 17 drives the core rod 1 and one end of the raw material wire away from the rotating connector 16 in the first direction. Under the action of the bushing 4 and damping between the main body 2 and the wire spool 3, the rotation of the main body 2 drives the wire spool 3 to rotate. The damping function is to prevent the main body 2 and the wire spool 3 from rotating freely and to prevent the raw material wire from becoming loose. At the same time, one end of the raw material wire is driven to move by the moving platform 17, so that the raw material wire is taut and can be wound on the core rod 1 to form a heating wire. When the moving table 17 moves to the end of the moving platform away from the rotating connector 16, the winding stops, the clamping end loosens the core rod 1, the moving table 17 moves to the end of the moving platform close to the rotating connector 16, the clamping end tightens the core rod 1 and the raw material wire again, the rotating connector rotates again, and at the same time the moving table 17 drives the core rod 1 and the raw material wire to move; this cycle repeats to realize the winding of the spiral heating wire; When a core rod 1 of a certain length is pulled out of the rotating connector 16, the winding stops. The core rod 1 is reinserted into the rotating connector 16, with one end extending into the inner ring of the wound spiral heating wire. The clamping end clamps the core rod 1 and the raw material wire again, thus allowing the winding of the spiral heating wire to continue. Theoretically, the spiral heating wire can be wound to an infinite length. The wound heating wire is coiled, packaged, and then shipped. Customers can cut the wire to the appropriate length according to the actual needs of different heating furnaces, eliminating the need to weld multiple fixed-length heating wires together, thus saving processes. Compared with existing technologies, the heating wire is wound in one go, eliminating the process of manufacturing multiple sections in batches, saving time and improving the quality of the heating wire. At the same time, it eliminates the need to set up multiple production lines to produce heating wires of different lengths, saving production costs. It should be noted that the guide nozzle 9 can be replaced according to customer needs to adapt to different heating wire specifications. Similarly, the first guide wheel 11 and the second guide wheel 13 can be replaced to make the wire groove and the raw material wire compatible.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed.
