Description

Technical Field

[0001] This utility model belongs to the field of cored wire technology, and in particular relates to a low-stress constant tension traction mechanism for cored wire. Background Technology

[0002] The cored wire traction mechanism is a core component in cored wire production. Its core function is to provide continuous, stable, and adjustable traction force to smoothly pull the core-filled strip through a series of forming dies, ultimately processing it into a dense cored wire. The performance of this mechanism directly determines the quality of the product, such as the uniformity of the core filling, the roundness of the wire, and the surface quality. However, the cored wire traction mechanism still has the following drawbacks in practical use: The cored wire traction mechanism has a fixed traction wheel (i.e., the mounting cylinder in the instruction manual). When it is necessary to transport cored wires of different diameters or specifications, the entire traction wheel assembly needs to be replaced, which is cumbersome, inefficient, and lacks flexibility. Secondly, the cored wire traction mechanism may lack an effective tension control mechanism, resulting in inconsistent tension of the cored wire during transportation. This can easily cause jumping, slippage, or accumulation, affecting the stability of subsequent processes and product quality. In order to maintain tension, traditional methods may use excessively tight clamping or traction, which will directly transmit excessive pressure to the soft cored wire sheath, causing it to undergo plastic deformation, damage, or even breakage, thereby affecting the sealing and uniformity of the internal material. Utility Model Content

[0003] The purpose of this utility model is to provide a low-stress constant tension traction mechanism for cored wires. By setting up an installation component, a mounting base, an installation cylinder, a reducer, and a U-shaped frame, it solves the problems that the cored wire traction mechanism cannot flexibly adapt to cored wires of different diameters, and that the tension of the cored wire is unstable and the internal stress is high during the traction process.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a low-stress constant tension traction mechanism for cored wire, comprising an installation assembly, a mounting base, a mounting cylinder, a reducer, and a U-shaped frame. The installation assembly includes two upright plates, each with two corresponding mounting bases on one side. Each mounting base has a mounting cylinder on its periphery. A mounting ring is fixed to the edge of each mounting base near the upright plate, and mounting bolts are inserted into each mounting ring in a circular array. A reducer is fixed to the side of each upright plate away from the mounting base. A U-shaped frame is provided between each mounting base and the upright plate, with a sliding block fixed to the end of the U-shaped frame away from the mounting base. A fastening bolt is rotatably connected to the side of the sliding block away from the U-shaped frame. The installation assembly includes two upright plates, with corresponding mounting bases on one side of each upright plate. Mounting cylinders are installed around the periphery of each mounting base, and the mounting bases are connected to the mounting cylinders via mounting rings and mounting bolts at their edges. A reducer is fixed to the other side of the upright plate to drive the mounting bases and mounting cylinders to rotate. A U-shaped frame is provided between the mounting bases and the upright plates, with the ends of the U-shaped frame connected via sliding blocks and fastening bolts to adjust the damping during the rotation of the mounting bases.

[0005] Furthermore, the mounting assembly also includes a base, a socket, and an adjustment screw hole. The bottom ends of the two upright plates are jointly fixed to the base, and the mounting seat is disposed above the base. Each upright plate has a socket on the side near the mounting seat corresponding to the position of the sliding block. The vertical portion of the upright plate in each socket is provided with an adjustment screw hole. The bottom ends of the two upright plates of the mounting assembly are jointly fixed to the base for support. The upright plates have sockets for the sliding block to be inserted, and the sockets are provided with adjustment screw holes for cooperating with fastening bolts to achieve position adjustment.

[0006] Furthermore, a connecting shaft is fixed at the center of one end of the mounting base near the upright plate. The connecting shaft of the lower mounting base is rotatably connected to the side of the upright plate near the mounting base. The connecting shaft is fixed at the center of one end of the mounting base near the upright plate. The connecting shaft of the lower mounting base is rotatably connected to the upright plate, allowing the mounting base to rotate around the shaft.

[0007] Furthermore, each of the mounting cylinders has an annular groove in the center of its periphery, and the end of the mounting cylinder near the mounting ring has mounting screw holes arranged in a ring array. The fastening bolts are threaded into the mounting screw holes. The annular groove in the center of the periphery of the mounting cylinder is used to accommodate and transport the cored wire. One end of the mounting cylinder has a mounting screw hole, which is fixedly connected to the mounting ring by the mounting bolt.

[0008] Furthermore, the output end of the reducer is fixed with a fixed shaft, which passes through the vertical plate and is fixed to the end of the connecting shaft of the mounting base located above. A drive motor is fixed to one side of the reducer, and the output end of the drive motor is fixed to the reducer. The output end of the reducer is fixed with a fixed shaft, which passes through the vertical plate and is fixed to the connecting shaft of the mounting base above. A drive motor is installed on one side of the reducer to provide power for it and drive the mounting base and mounting cylinder to rotate.

[0009] Furthermore, the sliding block is inserted into the socket and the fastening bolt is threaded into the adjusting screw hole. Each U-shaped frame is rotatably connected to a pressing roller. The pressing roller presses against the upper part of the mounting base near the vertical plate. The sliding block is inserted into the socket of the vertical plate, and the fastening bolt is screwed into the adjusting screw hole. The pressing roller installed in the U-shaped frame is in pressing contact with the end of the mounting base. By adjusting the fastening bolt, the degree of pressing is changed, thereby controlling the damping of the rotation of the mounting base and maintaining the stability of the core wire tension.

[0010] This utility model has the following beneficial effects: This invention solves the problem that the cored wire traction mechanism cannot flexibly adapt to cored wires of different diameters by setting up an installation component, a mounting base, an installation cylinder, and a reducer. The installation cylinder is connected to the mounting base through an installation ring and installation bolts. When replacement is needed, the installation cylinder can be removed simply by unscrewing the installation bolts and replaced with an installation cylinder with a ring groove of a different size, thereby quickly adapting to cored wires of different diameters and greatly improving the versatility and operating efficiency of the equipment.

[0011] This invention solves the problems of unstable tension and high internal stress of the cored wire during the traction process by setting up an installation component, mounting base, mounting cylinder, reducer, and U-shaped frame. An adjustable friction damping system is formed by the U-shaped frame, compression roller, sliding block, and fastening bolts. By tightening the fastening bolts, the sliding block can be pushed, causing the compression roller to press against the end face of the mounting base, thereby increasing the frictional resistance of the mounting base's rotation. When the drive side provides constant power, the damping force on the non-drive side ensures that the cored wire remains taut between the two mounting cylinders, achieving constant tension. Simultaneously, since the tension is achieved through rotational damping rather than direct mechanical compression, the pressure transmitted to the surface of the cored wire is uniform and controllable, significantly reducing the internal stress of the cored wire and protecting the wire from damage.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-5 This utility model relates to a low-stress constant tension traction mechanism for cored wire, comprising a mounting assembly 1, mounting bases 2, mounting cylinders 3, a reducer 4, and a U-shaped frame 5. The mounting assembly 1 includes two upright plates 102, each with two corresponding mounting bases 2 on one side. During operation, the mounting bases 2 are supported on a base 101, and the mounting cylinders 3 are connected therethrough. Mounting cylinders 3 are located around the periphery of both mounting bases 2. The mounting cylinders 3 compress and rotate, driving the cored wire to move. Mounting rings 201 are fixed to the edge of one end of the mounting base 2 near the upright plate 102. Each mounting ring 201 contains a ring array of mounting bolts 202. Ring 201 is connected to mounting cylinder 3 by mounting bolt 202. A reducer 4 is fixed on the side of the upright plate 102 away from the mounting base 2. When the reducer 4 is working, it drives the mounting base 2 and mounting cylinder 3 to rotate. A U-shaped frame 5 is provided between each mounting base 2 and the upright plate 102. The U-shaped frame 5 is connected to the extrusion roller 501. After the extrusion roller 501 is pressed, the damping of the rotation of the mounting base 2 is changed. A sliding block 502 is fixed at the end of the U-shaped frame 5 away from the mounting base 2. A fastening bolt 503 is rotatably connected to the side of the sliding block 502 away from the U-shaped frame 5. The sliding block 502 is connected to the fastening bolt 503. By rotating the fastening bolt 503, the damping of the rotation of the mounting base 2 is adjusted, and the tension of the cored wire is adjusted.

[0017] Specifically, the mounting component 1 also includes a base 101, a socket 103, and an adjustment screw hole 104. The base 101 is fixed to the bottom of the two upright plates 102. The mounting base 2 is set above the base 101. Each upright plate 102 has a socket 103 on the side near the mounting base 2 corresponding to the position of the sliding block 502. The vertical part of the upright plate 102 in each socket 103 is provided with an adjustment screw hole 104. The base 101 supports the two upright plates 102 on the working plane. The upright plates 102 are movably connected to the sliding block 502 through the socket 103 and the fastening bolt 503 is threadedly connected through the adjustment screw hole 104.

[0018] Furthermore, a connecting shaft 203 is fixed at the center of one end of the mounting base 2 near the vertical plate 102. The connecting shaft 203 located in the lower mounting base 2 is rotatably connected to the side of the vertical plate 102 near the mounting base 2. The mounting base 2 is rotatably connected to the vertical plate 102 or connected to the fixed shaft 401 of the reducer 4 through the connecting shaft 203, providing support for the mounting base 2 on the vertical plate 102.

[0019] Furthermore, each mounting cylinder 3 has an annular groove 301 in the middle of its periphery, and the end of the mounting cylinder 3 near the mounting ring 201 has mounting screw holes 302 arranged in an annular array. The fastening bolts 503 are threaded into the mounting screw holes 302. The annular grooves 301 on the periphery of the two corresponding mounting cylinders 3 are movably connected to the cored wire. During rotation, the cored wire is driven to be moved and transported.

[0020] Furthermore, a fixed shaft 401 is fixed to the output end of the reducer 4. The fixed shaft 401 passes through the vertical plate 102 and is fixed to the end of the connecting shaft 203 of the mounting base 2 located above. A drive motor 402 is fixed to one side of the reducer 4. The output end of the drive motor 402 is fixed to the reducer 4. The drive motor 402 drives the reducer 4 to work and drives the fixed shaft 401 to rotate. Through the rotation of the fixed shaft 401, the mounting base 2 located above is driven to rotate.

[0021] The operation process of this embodiment is as follows: During operation, when it is necessary to transport the cored wire, the drive motor 402 near the output side of the cored wire is started. The drive motor 402 drives the fixed shaft 401 to rotate. During the rotation of the fixed shaft 401, the mounting base 2 and the mounting cylinder 3 around it are rotated. During the rotation of the mounting cylinder 3, the cored wire is squeezed and transported from the annular grooves 301 around the two mounting cylinders 3 away from the drive side to the annular grooves 301 around the two mounting cylinders 3 on the drive side, and the cored wire is squeezed out. When facing the need to transport cored wires of different diameters, the operation of the drive motor 402 is stopped, the mounting bolt 202 on the mounting ring 201 is rotated, and the mounting bolt 202 is unscrewed from the mounting screw hole 302 at the end of the mounting cylinder 3. The mounting cylinder 3 is then removed, and the mounting cylinder 3 with a suitable inner diameter annular groove 301 is put on the mounting base 2. The mounting bolt 202 is then screwed back into the mounting screw hole 302 on the mounting cylinder 3 and tightened. This completes the need for the mounting cylinder 3 to transport cored wires of different diameters. Specific Implementation Example 2

[0022] Please see Figure 1-6 Based on the first specific embodiment, the sliding block 502 is inserted into the socket 103 and the fastening bolt 503 is threaded into the adjusting screw hole 104. Each U-shaped frame 5 is rotatably connected to a pressing roller 501. The pressing roller 501 and the upper part of the mounting base 2 near the vertical plate 102 press against each other. The sliding block 502 is movably inserted into the socket 103. When the fastening bolt 503 rotates, the position of the sliding block 502 is adjusted, so that the clamping force between the pressing roller 501 and the mounting base 2 changes, and the rotation damping of the mounting base 2 is adjusted.

[0023] The operation process of this embodiment is as follows: During operation, the position of the vertical plate 102 closer to the output side is determined among the two vertical plates 102. The vertical plate 102 closer to the output side is the output side and drive side of the cored wire. At this time, the two fastening bolts 503 on the other vertical plate 102 are rotated. After the fastening bolts 503 rotate, they drive the sliding block 502 to push the extrusion roller 501 to press against the mounting base 2. This allows the mounting base 2 to rotate only after being subjected to a constant driving force. Then, the drive motor 402 on the reducer 4 closer to the output side can be started. The drive motor 402 drives the reducer 4 to work, driving the connecting shaft 203 to rotate, causing the mounting base 2 and the mounting cylinder 3 to rotate. The cored wire in the annular groove 301 is driven to move. Through the extrusion roller 501 on the U-shaped frame 5 pressing against the mounting base 2, damping is generated, allowing the cored wire between the two vertical plates 102 to maintain a constant tension. During constant tension operation, through friction traction, the tension is evenly applied to the cored wire, and no large internal stress is generated on the surface of the cored wire.
