Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, specifically relating to a spinning tube structure with a built-in cooling channel. Background Technology

[0002] The wire drawing machine is an important piece of equipment in a high-speed wire rod production line. Its main structure consists of a motor that transmits rotational motion to the hollow shaft of the wire drawing machine through a pair of spiral bevel gears. The steel rolled by the high-speed wire rod mill is fed by pinch rollers and enters the hollow shaft of the high-speed rotating wire drawing machine. It is then deformed by force through the wire drawing tube. The steel changes from high-speed linear motion to a near-static circle, which is scattered on the air-cooled roller conveyor. After being packaged, it becomes wire rod coils, commonly known as wire rod.

[0003] During operation, the wire-spinning tube needs to accommodate the passage of reinforcing bars for extended periods. This passage causes compression and wear on the tube, leading to rapid damage and making it a frequently replaced consumable part. Most existing wire-spinning tubes are fixed with bolts, and to prevent them from falling out, the bolts require high torque. Disassembly requires specialized equipment, making the replacement process demanding on the equipment and hindering efficient replacement. Therefore, this application proposes a wire-spinning tube structure with an integrated cooling channel. Utility Model Content

[0004] The purpose of this invention is to provide a spinneret structure with a built-in cooling channel to solve the problem mentioned in the background art that in order to prevent the spinneret from falling off, the bolts require a large torque, and special equipment is needed during disassembly, which leads to high requirements for the equipment during the spinneret replacement process and affects the replacement work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire-spinning tube structure with a built-in cooling channel, comprising a wire-spinning outer tube and a wire-exiting tube, wherein the wire-spinning outer tube is connected to the wire-exiting tube, and a wire-exiting port is provided inside the wire-exiting tube; wherein a cooling pipe and a compressed gas feed pipe connected to the cooling pipe are provided inside the wire-spinning outer tube. A silk-spinning inner tube is provided at the middle position of the inner side of the outer silk-spinning tube. The inner silk-spinning inner tube is provided with several inner air inlets, which are connected to the cooling pipe. A sleeve is provided between the inner tube and the cooling tube. An outer air inlet is provided inside the sleeve and aligned with the inner air inlet. Insert plates are provided on the outer wall of the inner tube and distributed parallel to the tube body. A slot is provided inside the sleeve to cooperate with the insert plates. The sleeve is provided with an inner positioning ring for limiting the insertion depth of the inner tube of the wire-spinning device, and an outer positioning mechanism located at the end of the sleeve away from the inner positioning ring to block the insertion plate from moving away from the sleeve.

[0006] Preferably, the outer tube for spinning is provided with a tapered sleeve that is fitted over the outside of the cooling tube.

[0007] Preferably, a plurality of parallel support rings are provided between the conical sleeve and the inner wall of the outer tube.

[0008] Preferably, a shock-absorbing pad is provided on the side of the support ring near the tapered sleeve, and the cross-section of the shock-absorbing pad is set in a U-shape.

[0009] Preferably, the cooling pipe is provided with a plurality of heat sinks arranged in a ring array around the center line of the outer spinning tube, and the heat sinks are connected to the inner wall on the side close to the center line of the outer spinning tube.

[0010] Preferably, an expansion tube is provided on the side of the inner spinning tube away from the outer spinning tube, and the expansion tube is in the shape of a trumpet.

[0011] Preferably, the outer wall of the sleeve is fitted with the outer wall of the cooling pipe, and the inner wall of the sleeve is fitted with the inner tube of the spinning tube.

[0012] Preferably, the insert plate is square in shape, and there are two insert plates arranged in a circumferential array around the center line of the inner tube of the spinning tube.

[0013] Preferably, three external positioning mechanisms are provided, and the three external positioning mechanisms are arranged in a circumferential array around the center line of the outer spinning tube.

[0014] Preferably, the external positioning mechanism includes a pressure block that can abut against the outer wall of the inner tube of the spinning tube, and a pressure box that slides with the pressure block. The pressure box is provided with a spring for applying pressure to move the pressure block toward the side closer to the outer wall of the inner tube of the spinning tube.

[0015] Beneficial effects: This utility model provides a wire-spinning tube structure with a built-in cooling channel. The inner wire-spinning tube and the sleeve are connected by an insertion method, so that the inner air inlet on the inner wire-spinning tube can be aligned with the outer air inlet on the sleeve. At the same time, an inner positioning ring at the sleeve limits the insertion depth of the inner wire-spinning tube, and an outer positioning mechanism located at the end of the sleeve away from the inner positioning ring can block the insertion plate from moving away from the sleeve. After the inner wire-spinning tube is inserted into the sleeve, the inner and outer end faces of the inner wire-spinning tube are positioned by the inner positioning ring and the outer positioning mechanism, thus completing the fixing of the inner wire-spinning tube.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1-5 As shown in the figure, the present invention provides a wire-spinning tube structure with a built-in cooling channel, including a wire-spinning outer tube 1 and a wire-exiting tube 2. The wire-spinning outer tube 1 is connected to the wire-exiting tube 2. The wire-exiting tube 2 is provided with a wire-exiting port 3. The steel bar passes through the internal components of the wire-spinning outer tube 1 and reaches the wire-exiting tube 2, and is discharged from the wire-exiting port 3. It is then wound into a coil by a subsequent winding mechanism. The wire-spinning outer tube 1 is provided with a cooling pipe 4 and a compressed gas inlet pipe 8 connected to the cooling pipe 4. The compressed gas inlet pipe 8 is connected to a compression tank for storing compressed gas. Compressed gas enters the cooling pipe 4 through the compressed gas feed pipe 8, flows through the cooling pipe 4 to the inner spinning tube 10, and enters the inner spinning tube 10 through the inner air inlet 12 to exchange the heat generated by the friction between the gas and the inner spinning tube 10 during the movement, thus preventing the inner spinning tube 10 from overheating.

[0020] Specifically, in order to install the cooling pipe 4, a tapered sleeve 5 is provided inside the outer tube 1 to fit the outside of the cooling pipe 4. Several parallel support rings 6 are provided between the tapered sleeve 5 and the inner wall of the outer tube 1. A shock-absorbing pad 7 is provided on the side of the support ring 6 near the tapered sleeve 5. The cross-section of the shock-absorbing pad 7 is set in a U-shape.

[0021] The shock-absorbing pad 7 and the support ring 6 are used to install the tapered sleeve 5 to isolate the cooling pipe 4 from the outside, so as to avoid the cooling pipe 4 being affected by the external temperature. At the same time, the shock-absorbing pad 7 can reduce the impact of the vibration of the inner wire-spinning tube 10 caused by the movement of the steel bars on the outer wire-spinning tube 1, and reduce noise.

[0022] Specifically, the cooling pipe 4 is provided with a number of heat sinks 9 arranged in a ring array around the center line of the outer tube 1, and the heat sinks 9 are connected to the inner wall on the side close to the center line of the outer tube 1.

[0023] More specifically, an inner tube 10 is provided at the middle position of the inner side of the outer tube 1, and an outer expansion tube 11 is provided on the side of the inner tube 10 away from the outer tube 1. The outer expansion tube 11 is flared to facilitate the entry of the reinforcing bar. Several inner air inlets 12 are provided inside the inner tube 10, and the inner air inlets 12 are connected to the cooling pipe 4.

[0024] To facilitate the installation and replacement of the inner tube 10, a sleeve 13 is provided between the inner tube 10 and the cooling pipe 4. The outer wall of the sleeve 13 is in contact with the outer wall of the cooling pipe 4, and the inner wall of the sleeve 13 is in contact with the inner tube 10. Both the inner and outer walls of the sleeve 13 are connected by a clearance fit. An outer air inlet is provided inside the sleeve 13, which is aligned with the inner air inlet 12 and is connected to the cooling pipe 4. Insert plates 14 are provided on the outer wall of the inner tube 10, which are parallel to the tube body of the inner tube 10. The insert plates 14 are square in shape, and there are two insert plates 14. The two insert plates 14 are arranged in a circumferential array around the center line of the inner tube 10. A slot is provided inside the sleeve 13 to cooperate with the insert plates 14.

[0025] Specifically, the sleeve 13 is provided with an inner positioning ring 16 for limiting the insertion depth of the inner tube 10 for spinning, and an outer positioning mechanism 15 located at the end of the sleeve 13 away from the inner positioning ring 16 to block the insertion plate 14 from moving away from the sleeve 13.

[0026] For reference Figure 3 There are three external positioning mechanisms 15, and the three external positioning mechanisms 15 are arranged in a circumferential array around the center line of the outer spinning tube 1. The external positioning mechanism 15 includes a pressure block 1501 that can abut against the outer wall of the inner spinning tube 10, and a pressure box 1502 that slides with the pressure block 1501. The pressure box 1502 is provided with a spring for applying pressure to the pressure block 1501 to move closer to the outer wall of the inner spinning tube 10. The spring is a metal spring with a length of 5mm and a wire diameter of 2mm.

[0027] In summary, this utility model embodiment provides a wire-spinning tube structure with a built-in cooling channel. The wire-spinning inner tube 10 and the sleeve 13 are connected by an insertion method, so that the inner air inlet 12 on the wire-spinning inner tube 10 and the outer air inlet on the sleeve 13 can be aligned. At the same time, an inner positioning ring 16 at the sleeve 13 restricts the insertion depth of the wire-spinning inner tube 10, and an outer positioning mechanism 15 located at the end of the sleeve 13 away from the inner positioning ring 16 can block the insertion plate 14 from moving away from the sleeve 13. After the wire-spinning inner tube 10 is inserted into the sleeve 13, the inner and outer end faces of the wire-spinning inner tube 10 are positioned by the inner positioning ring 16 and the outer positioning mechanism 15, thus completing the fixing of the wire-spinning inner tube 10. The fixed wire-spinning inner tube 10 requires fewer steps to disassemble and assemble, and it is convenient to replace the wire-spinning inner tube 10 that is worn due to the impact of the moving steel bar.

[0028] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
