Description

Technical Field

[0001] This utility model relates to the field of copper wire production, and in particular to a stretching device for copper wire production. Background Technology

[0002] Copper wire is a linear conductor made primarily of copper. Its conductivity is second only to silver, but it is currently one of the most widely used linear conductors due to its lower cost.

[0003] During the production process, copper wire needs to be stretched. During the stretching process, the internal grain structure of the copper wire changes, the grains become finer, which increases the tensile strength of the copper wire. At the same time, copper drawn into fine wires can transmit current more efficiently, reduce resistance loss, and improve conductivity. Specialized stretching equipment is generally required during the stretching process.

[0004] According to existing patent CN219944154U, a stretching device for processing composite copper wire is disclosed, including a mounting plate and a protective component disposed on the mounting plate to prevent the composite copper wire from being stretched and broken. The device uses an inner support rod whose maximum allowable tensile force is less than the maximum allowable tensile force A of the composite copper wire, causing the inner support rod to break first. At this time, the guide ring is subjected to the downward traction force of the composite copper wire and slides down along the support rod, thus alleviating the instantaneous increase in traction force on the composite copper wire. At the same time, the sliding frame compresses the spring, and under the action of the spring, the vibration amplitude of the guide ring sliding down the inner support rod can be reduced, thereby improving the stability of the composite copper wire during stretching.

[0005] In the actual operation, due to the large force when the copper wire is stretched, the spring begins to contract when the guide ring slides down. At this time, the guide ring moves the fastest. Since the copper wire is generally stretched at a constant speed, the guide ring will compress the spring after the initial descent and continue to descend. The tighter the spring is, the greater the pressure required. This also leads to uneven descent speed of the guide ring. At the same time, if the guide ring descends too long, the tensile strength of different segments of the copper wire will be different, which can easily affect the final quality of the finished copper wire product.

[0006] Therefore, it is necessary to provide a new stretching device for copper wire production to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a stretching device for copper wire production.

[0008] The copper wire stretching device provided by this utility model includes a pad, two limiting posts are fixedly connected to the top of the pad, an mounting plate is fixedly connected between the tops of the two limiting posts, a slidably connected limiting ring is sleeved on each limiting post, a guide ring is fixedly connected between the two limiting rings, and a limiting block is fixedly connected to one side of each limiting ring.

[0009] A sleeve is fixedly connected to the bottom of the mounting plate near the limiting block. A mounting rod is rotatably connected inside the sleeve. Mounting brackets are fixedly connected to both ends of the mounting rod. Each mounting bracket is aligned with the limiting block on the same side. Several short brackets are fixedly connected to both sides of the mounting bracket. A limiting roller is rotatably connected between two short brackets at the same height.

[0010] Preferably, the bottom of the limiting block is provided with a guide slope, and a limiting groove is formed on the side of the guide slope near the limiting ring, and the guide slope contacts the top of the limiting roller at the same height.

[0011] Preferably, long brackets are fixedly connected to both sides of the bottom of the mounting bracket, and a limiting rod is fixedly connected between the long brackets. The limiting rod is located directly below the limiting groove of the limiting block on the same side, and a torsion spring is fixedly connected between the mounting rod and the inner wall of the sleeve.

[0012] Preferably, each of the limiting posts is fitted with a spring, the top of the spring is fixedly connected to the bottom of the limiting ring on the same side, and the limiting post has a stepped structure that is wider at the bottom and narrower at the top.

[0013] Preferably, positioning ring A and positioning ring B are fixedly connected to the top two sides of the pad, respectively.

[0014] Preferably, a fixing frame A is fixedly connected to the top of the pad near the positioning ring A. The positioning ring A is located between the guide ring and the fixing frame A. A mounting shaft is fixedly connected to one side of the fixing frame A, and a take-up drum that is rotatably connected is sleeved on the mounting shaft.

[0015] Preferably, a fixing frame B is fixedly connected to the side of the pad near the positioning ring B, the positioning ring B is located between the guide ring and the fixing frame B, a winding rod is rotatably connected to the fixing frame B, and a motor for driving the winding rod to rotate is fixedly connected to one side of the fixing frame B.

[0016] Compared with related technologies, the stretching device for copper wire production provided by this utility model has the following advantages:

[0017] In this invention, when stretching copper wire, if the copper wire is about to reach its maximum stretching threshold, during the stretching process, the limiting block uses a guide inclined surface to press against the limiting roller. Through the cooperation of the guide inclined surface and the rotating limiting roller, the direction of the force is changed, causing the mounting frame to rotate. This separates the current limiting roller from the limiting block. At this point, the pressure of the copper wire on the guide ring causes the guide ring to drive the limiting ring down along the limiting post. Due to the torsion spring, when the limiting block moves below the limiting roller, the pressure on the limiting roller disappears, and the torsion spring begins to rebound, causing the mounting frame to return to its original position. The lower limiting roller continues to limit the limiting block. Because the guide ring has descended to a certain height, the stretching force of the copper wire can be alleviated, and uneven descent speed of the guide ring is avoided. Furthermore, excessively long descent of the guide ring can easily lead to different tensile strengths in different segments of the copper wire, potentially affecting the final quality of the finished copper wire product.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The copper wire stretching device provided in this embodiment includes a pad 1. Two limiting posts 2 are fixedly connected to the top of the pad 1. A mounting plate 21 is fixedly connected between the tops of the two limiting posts 2. Each limiting post 2 is fitted with a slidingly connected limiting ring 3. A guide ring 31 is fixedly connected between the two limiting rings 3. A positioning ring A11 and a positioning ring B12 are fixedly connected to the top two sides of the pad 1, respectively. A fixing frame A5 is fixedly connected to the top of the pad 1 near the positioning ring A11. The positioning ring A11 is located between the guide ring 31 and the fixing frame. Between A5, a mounting shaft 51 is fixedly connected to one side of the fixed frame A5. A take-up drum 52 is rotatably connected to the mounting shaft 51. A damping pad is provided between the inner wall of the take-up drum 52 and the mounting shaft 51. The speed of the take-up drum 52 can be greatly reduced by the damping pad. A fixed frame B6 is fixedly connected to the side of the pad 1 near the positioning ring B12. The positioning ring B12 is located between the guide ring 31 and the fixed frame B6. A winding rod 61 is rotatably connected to the fixed frame B6. A motor 62 for driving the winding rod 61 to rotate is fixedly connected to one side of the fixed frame B6.

[0027] It should be noted that when stretching the copper wire, the copper wire is wound onto the take-up drum 52, which is then inserted into the mounting shaft 51. The end of the copper wire wound on the take-up drum 52 is then passed through the positioning ring A11, the guide ring 31, and the positioning ring B12 in sequence, and then wound around the take-up rod 61. At this time, the motor 62 is turned on, and the take-up rod 61 is rotated by the motor 62. The copper wire is then wound up by the take-up rod 61 at a normal speed, while the take-up drum 52 rotates at a relatively slow speed and the fixed guide ring 31 completes the stretching of the copper wire.

[0028] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Each limiting ring 3 has a limiting block 32 fixedly connected to one side. The bottom of the limiting block 32 has a guide slope 33, and a limiting groove 34 is formed on the guide slope 33 near the limiting ring 3. Each limiting post 2 is fitted with a spring 22, the top of which is fixedly connected to the bottom of the limiting ring 3 on the same side. The limiting post 2 has a stepped structure that is wider at the bottom and narrower at the top. A sleeve 4 is fixedly connected to the bottom of the mounting plate 21 near the limiting block 32. An mounting rod 41 is rotatably connected inside the sleeve 4, and mounting brackets 42 are fixedly connected to both ends of the mounting rod 41. The mounting bracket 42 is aligned with the limiting block 32 on the same side. Several short brackets 43 are fixedly connected to both sides of the mounting bracket 42. Limiting rollers 44 are rotatably connected between two short brackets 43 at the same height. The guide slope 33 contacts the top of the limiting roller 44 at the same height. Long brackets 45 are fixedly connected to both sides of the bottom of the mounting bracket 42. Limiting rods 46 are fixedly connected between the long brackets 45. The limiting rods 46 are located directly below the limiting groove 34 of the limiting block 32 on the same side. A torsion spring 47 is fixedly connected between the mounting rod 41 and the inner wall of the sleeve 4.

[0029] It should be noted that the torque of the torsion spring 47 is less than the force required for the copper wire to break. During normal stretching of the copper wire, the limiting roller 44 limits the limiting block 32, thereby limiting the guide ring 31. At this time, normal stretching of the copper wire is possible. However, when the copper wire is about to reach the breakage threshold, the pressure of the copper wire on the guide ring 31 is greater than the torque of the torsion spring 47. At this point, the limiting block 32 moves downward along with the limiting ring 3 and contacts the rotating limiting roller 44 through the guide inclined surface 33, thereby changing the direction of the downward force. The mounting bracket 42 will rotate. When the limiting roller 44, which is in contact with the bottom of the limiting block 32, moves away from the bottom of the limiting block 32, the pressure applied by the copper wire will cause the limiting ring 3 to descend along the limiting post 2 and compress the spring 22. When the limiting block 32 moves below the limiting roller 44, the squeezing force of the limiting block 32 on the limiting roller 44 disappears, the torsion spring 47 begins to rebound, and the mounting bracket 42 returns to its original position. At this time, the lower limiting roller 44 continues to cooperate with the limiting block 32 to limit the height of the guide ring 31. The guide ring 31 descends a certain distance, which alleviates the tension on the copper wire, allowing it to continue its normal stretching process without breaking. The design of multiple limiting rollers 44 provides multiple protections against the copper wire reaching its breakage threshold. When the guide ring 31 reaches its lowest height, the limiting block 32 moves with the guide ring 31 above the limiting rod 46. At this point, the limiting rod 46 engages in the limiting groove 34 at the bottom of the limiting block 32, thus restricting the guide ring 31 and preventing it from being damaged by the limiting effect of the various limiting rollers 44. The copper wire continuously applies pressure to the guide ring 31, causing the guide ring 31 to descend continuously, resulting in uneven tension on the copper wire. After the copper wire stretching is completed, manually rotate the mounting bracket 42 to separate the limiting roller 44 or the limiting rod 46 from the limiting block 32. At this time, the rebound force of the spring 22 can drive the limiting ring 3 and the guide ring 31 to rise along the limiting post 2, thereby resetting the guide ring 31. Then, release the mounting bracket 42, and the reaction force of the torsion spring 47 will drive the mounting bracket 42 to reset, so that the stretching work of the next copper wire can continue.

[0030] The working principle of the copper wire stretching device provided by this utility model is as follows:

[0031] First, place the device in the designated working position, then power it on for use. When stretching the copper wire, wind the copper wire onto the take-up drum 52, then insert the take-up drum 52 onto the mounting shaft 51. Then, pass the end of the copper wire wound on the take-up drum 52 through the positioning ring A11, guide ring 31 and positioning ring B12 in sequence, and then wrap the end around the take-up rod 61. At this time, turn on the motor 62, and use the motor 62 to drive the take-up rod 61 to rotate. At this time, the copper wire is wound up by the take-up rod 61 at a normal speed, while the take-up drum 52 at a relatively slow speed and the fixed guide ring 31 complete the stretching of the copper wire.

[0032] During this process, if the copper wire is stretched normally, the limiting roller 44 limits the limiting block 32, thereby limiting the guide ring 31, and the copper wire can be stretched normally at this time.

[0033] When the copper wire is about to reach the breaking threshold, the pressure of the copper wire on the guide ring 31 is greater than the torque of the torsion spring 47. At this time, the limiting block 32 will move downward with the limiting ring 3 and contact the rotating limiting roller 44 through the guide inclined surface 33, thereby changing the direction of the downward force. At this time, the mounting frame 42 will rotate. When the limiting roller 44, which is attached to the bottom of the limiting block 32, moves away from the bottom of the limiting block 32, the pressure applied by the copper wire will cause the limiting ring 3 to descend along the limiting post 2 and compress the spring 22. When the limiting block 32 moves below the limiting roller 44, the squeezing force of the limiting block 32 on the limiting roller 44 disappears, the torsion spring 47 begins to rebound, and the mounting frame 42 returns to its position. At this time, the lower limiting roller 44 continues to cooperate with the limiting block 32 to limit the height of the guide ring 31 and continue to stretch the copper wire.

[0034] When the guide ring 31 moves to its lowest height, the limiting block 32 will move with the limiting ring 3 to the top of the limiting rod 46. At this time, the limiting rod 46 will be inserted into the limiting groove 34 at the bottom of the limiting block 32, thereby restricting the guide ring 31. This prevents the guide ring 31 from losing its limiting effect due to the limiting rollers 44, and the copper wire from continuously applying pressure to the guide ring 31, causing the guide ring 31 to continue to descend, resulting in uneven tension on the copper wire.

[0035] After the copper wire stretching is completed, manually rotate the mounting bracket 42 to separate the limiting roller 44 or the limiting rod 46 from the limiting block 32. At this time, the rebound force of the spring 22 can drive the limiting ring 3 and the guide ring 31 to rise along the limiting post 2, thereby resetting the guide ring 31. Then, release the mounting bracket 42, and the reaction force of the torsion spring 47 will drive the mounting bracket 42 to reset, so that the stretching work of the next copper wire can continue.
