Description

Technical Field

[0001] This utility model belongs to the field of wire and cable drawing technology, and in particular, it relates to a wire and cable drawing device. Background Technology

[0002] Wires and cables are ubiquitous in daily life. All electrical appliances in our homes, such as lighting, air conditioners, refrigerators, televisions, and kitchen appliances, need to be connected to a power source via wires and cables to obtain the necessary electrical energy. Communication systems, security and monitoring, transportation, and public facilities also require wires and cables to be connected to a power source. Each of these scenarios requires a wide variety of wire and cable diameters, necessitating wire and cable drawing devices.

[0003] Current cable drawing devices require drawing dies to precisely control the wire diameter during the drawing process. Multiple drawing dies are typically used, with gradually decreasing inner diameters to achieve progressive wire drawing. Currently, these dies are usually installed with bolts to improve stability. However, the dies are subjected to significant forces during use, and different batches of cables require different dies. The bolt-mounted method is extremely inconvenient for disassembly and installation, hindering quick replacement. Therefore, a new cable drawing device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a wire and cable drawing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire and cable drawing device, comprising an mounting plate for installing the wire and cable drawing device and a drawing die for drawing wire and cable. An annealing groove is fixedly installed on the side wall of the mounting plate, and multiple drawing discs are rotatably installed on the side wall of the mounting plate. Two fixing plates are symmetrically fixedly installed on the side wall of the mounting plate, and a placement plate is connected to the end of the fixing plate. A cover plate is hinged to the top surface of the placement plate. An arc-shaped groove is opened at the bottom of the cover plate and the top surface of the placement plate. The drawing die is installed inside the arc-shaped groove.

[0006] A connecting rod is rotatably mounted on one side of the cover plate. A slot is provided on the side wall of the connecting rod. Two fixing blocks are symmetrically fixed to the side wall of the placement plate. An installation groove is provided on the side of the fixing block near the connecting rod. A push spring is fixedly installed in the installation groove. A locking block is connected to the end of the push spring and extends into the slot.

[0007] Preferably, a limit ring is fixedly sleeved on the outer wall of the card block, and an annular groove is formed in the mounting groove.

[0008] Preferably, the limiting ring fixedly installed on the side wall of the card block is slidably connected to the inside of the annular groove opened on the inner wall of the mounting groove.

[0009] Preferably, both the end of the card block and the inside of the card slot are arc-shaped.

[0010] Preferably, the sidewall of the wire drawing die is fixedly installed with multiple semi-circular clamping plates, and the arc-shaped grooves opened in the sidewalls of the cover plate and the placement plate are all provided with arc-shaped clamping slots, and the semi-circular clamping plates are engaged with the corresponding arc-shaped clamping slots.

[0011] Preferably, a pull rod is fixedly connected to the side wall of the connecting rod.

[0012] Preferably, a circulating filter pump is fixedly installed on the side wall of the annealing tank, and the water inlet of the circulating filter pump extends into the interior of the annealing tank.

[0013] Preferably, the circulating filter pump has a rectangular hole on its side wall, and a filter screen is slidably installed inside the rectangular hole.

[0014] Preferably, the filter screen is slidably and sealed to the inner wall of the circulating filter pump.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This wire and cable drawing device, thanks to its structure consisting of a placement plate, cover plate, connecting rod, fixing block, mounting groove, locking block, and push spring, allows the drawing die to be placed in the arc-shaped groove on the top surface of the placement plate. The cover plate is then flipped over to the top surface of the placement plate, and the connecting plate is then flipped over and moved between the two fixing blocks. When the connecting rod contacts the locking block on the side wall of the fixing block, the arc-shaped end of the locking block, combined with the downward pressure of the connecting rod, pushes the locking block into the mounting groove until the locking groove on the side wall of the connecting rod aligns with the locking block. At this point, the push spring pushes the locking block into the locking groove. Since both the locking groove and the locking block have arc-shaped ends, when the drawing die needs to be disassembled, simply pulling the connecting rod outwards pushes the locking block into the mounting groove through the arc-shaped surface of the locking groove until the locking block and the locking groove are misaligned. This allows for quick disassembly and installation of the drawing die.

[0017] This wire and cable drawing device, thanks to the semi-circular clamping plate and the arc-shaped clamping groove, allows the wire drawing die to be installed by attaching the semi-circular clamping plate on the side wall of the wire drawing die to the arc-shaped clamping groove on the top surface of the placement plate. Then, the cover plate is flipped over and attached to the top of the wire drawing die. The multiple arc-shaped clamping plates are staggered to prevent the wire drawing die from rotating during use and to increase the stability of the wire drawing die, enabling it to withstand the forces it is subjected to during use.

[0018] This wire and cable drawing device benefits from the design of a circulating filter pump and a filter screen. The circulating filter pump pumps the liquid in the annealing tank into the circulating filter pump, and then filters the liquid through the filter screen. The filtered liquid is then fed back into the annealing tank through the water inlet pipe. This prevents excessive impurities in the liquid from affecting the drawing of the wire and cable.

[0019] Compared with existing technologies, this cable drawing device allows for easy replacement of the drawing dies used for cable drawing, thereby further improving the efficiency of cable drawing. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] like Figures 1 to 5 A wire and cable drawing device is shown.

[0032] A wire drawing device typically consists of a wire feeding unit, a wire drawing coil, a winding unit, a wire drawing die 9, and an annealing unit. The wire drawing coil is used to pull the cable out of the wire feeding coil and provide tension so that the cable passes through the wire drawing die 9. The wire drawing die 9 thins the cable, and then the winding rollers wind up the drawn cable. Annealing is used to cool the drawn cable and restore its flexibility.

[0033] The main structure consists of an installation plate 1 for installing a wire and cable drawing device and a wire and cable drawing die 9. An annealing tank 2 is fixedly installed on the side wall of the installation plate 1, and multiple drawing discs 3 are rotatably installed on the side wall of the installation plate 1. The lower half of the multiple drawing discs 3 are all immersed in the liquid in the annealing tank 2, so that the wire can be annealed at the same time as drawing, thereby further improving the processing efficiency of cable drawing.

[0034] Two fixing plates 6 are symmetrically fixedly installed on the side wall of the mounting plate 1, and the end of the fixing plate 6 is connected to the placement plate 8. The top surface of the placement plate 8 is hinged to the cover plate 7. The bottom of the cover plate 7 and the top surface of the placement plate 8 are both provided with arc grooves. When the center line of the arc grooves at the bottom of the cover plate 7 and the top surface of the placement plate 8 are combined, they are parallel to the highest point of the wire drawing disc 3. The wire drawing die 9 is installed inside the arc groove. After the wire drawing die 9 is installed between the placement plate 8 and the cover plate 7, the wire is passed through the wire drawing die 9 and wrapped around the outside of the wire drawing disc 3. At this time, the wires between two adjacent wire drawing discs 3 can remain parallel.

[0035] A connecting rod 10 is rotatably mounted on one side of the cover plate 7. A slot 11 is formed on the side wall of the connecting rod 10. Two fixing blocks 12 are symmetrically fixed to the side wall of the placement plate 8. The two fixing blocks 12 are installed on both sides of the connecting rod 10. An installation groove 13 is formed on the side of the fixing block 12 closest to the connecting rod 10. A push spring 14 is fixedly installed in the installation groove 13. This push spring 14 is a damping spring. A locking block 15 is connected to the end of the push spring 14, and the locking block 15 extends into the slot 11. Both the end of the locking block 15 and the interior of the slot 11 are arc-shaped. Thanks to the structure of the placement plate 8, cover plate 7, connecting rod 10, fixing blocks 12, installation groove 13, locking blocks 15, and push spring 14, the wire drawing die 9 is placed in the arc-shaped groove on the top surface of the placement plate 8. Then, the cover plate 7 is flipped to the top surface of the placement plate 8, and then the connecting rod 10 is flipped. When the connecting rod 10 is moved between the two fixed blocks 12, and the connecting rod 10 contacts the locking block 15 on the side wall of the fixed block 12, the locking block 15 is arc-shaped at the end. As the connecting rod 10 is pressed down, the locking block 15 can be pushed into the interior of the mounting groove 13 until the locking groove 11 on the side wall of the connecting rod 10 is opposite to the locking block 15. At this time, the push spring 14 will push the locking block 15 into the locking groove 11. Since both the locking groove 11 and the end of the locking block 15 are arc-shaped, when it is necessary to disassemble the wire drawing die 9, simply pull the connecting rod 10 outward. The arc surface of the locking groove 11 can push the locking block 15 into the mounting groove 13 until the locking block 15 is misaligned with the locking groove. This achieves the purpose of quickly disassembling and installing the wire drawing die 9. The end of the locking block 15 extending to the outside of the mounting groove 13 and the inside of the locking groove 11 are both arc-shaped and match each other.

[0036] A limiting ring 16 is fixedly sleeved on the outer wall of the locking block 15. An annular groove is provided in the mounting groove 13. The limiting ring 16 fixedly installed on the side wall of the locking block 15 is slidably connected to the annular groove provided in the inner wall of the mounting groove 13. The limiting ring 16 can effectively limit the sliding direction of the locking block 15 when it slides, and at the same time further improve the stability of the locking block 15 when it slides.

[0037] Multiple semi-circular clamping plates 17 are fixedly installed on the side wall of the wire drawing die 9. Arc-shaped slots 18 are opened in the arc-shaped grooves on the side walls of the cover plate 7 and the placement plate 8. The semi-circular clamping plates 17 are engaged with the corresponding arc-shaped slots 18. Thanks to the setting of the semi-circular clamping plates 17 and the arc-shaped slots 18, when the wire drawing die 9 is installed, the semi-circular clamping plates 17 on the side wall of the wire drawing die 9 are engaged with the corresponding arc-shaped slots 18 opened in the arc-shaped grooves on the top surface of the placement plate 8. Then, the cover plate 7 is flipped and engaged above the wire drawing die 9. The multiple semi-circular clamping plates 17 are staggered with each other, which can prevent the wire drawing die 9 from rotating during use and increase the stability of the wire drawing die 9, so as to withstand the force it is subjected to during use.

[0038] A pull rod 19 is fixedly connected to the side wall of the connecting rod 10. The pull rod 19 is easy to hold and can drive the connecting rod 10 to move.

[0039] A circulating filter pump 20 is fixedly installed on the side wall of the annealing tank 2. The inlet of the circulating filter pump 20 extends into the interior of the annealing tank 2. The essence of the circulating filter pump 20 is to "make the liquid move and remove impurities in the flow". The overall process forms a closed loop: drawing in the liquid to be treated: the pump body draws in the liquid containing impurities through negative pressure. The main working process of this equipment is as follows:

[0040] Powered liquid propulsion: The motor drives the impeller to rotate, converting mechanical energy into liquid kinetic energy, which propels the liquid to flow towards the filtration unit;

[0041] Filtration and separation of impurities: Liquid flows through different filter media such as cotton, activated carbon, and quartz sand, and impurities are removed by physical or chemical means;

[0042] Cleaning liquid return: The filtered clean liquid is pushed back to the original container, completing one cycle.

[0043] The circulating filter pump 20 has a rectangular hole on its side wall, and a filter screen 22 is slidably installed in the rectangular hole. The filter screen 22 is used to filter impurities in the liquid. When it needs to be cleaned after long-term use, the filter screen 22 can be pulled out to clean or replace it.

[0044] The filter screen 22 slides and seals against the inner wall of the circulating filter pump 20, thereby improving the sealing performance between the filter screen 22 and the circulating filter pump 20, and further improving the filtration effect of the filter screen 22.

[0045] Working principle

[0046] In use, the wire and cable drawing device first winds the wire on the unwinding reel 4 onto the first drawing reel 3, wraps it once, and then passes it through the first drawing die 9. Next, the wire is wound onto the second drawing reel 3, wrapped once, and then passed through the second drawing die 9. Finally, it is wound onto the last drawing reel 3 and then onto the take-up reel 5, thus completing the cable winding. When the drawing die 9 needs to be replaced, first, hold the pull rod 19 and pull the connecting rod 10. As the pull rod 19 is pulled, the relative pushing block 15 retracts into the mounting groove 13, while simultaneously compressing the push spring 14 until the block 15 and the groove 11 are misaligned. This releases the limiting position of the connecting rod 10. Then, the cover plate 7 is flipped upwards, allowing the drawing die 9 to be removed. Remove the wire drawing die 9 and place the semi-circular clamping plate 17 on the side wall of the die to be replaced into the arc-shaped clamping groove 18 inside the arc-shaped groove on the top surface of the placement plate 8. Then flip the cover plate 7 and clamp it above the wire drawing die 9 to clamp the wire drawing die 9. Then hold the pull rod 19 to drive the connecting rod 10 to flip between the two fixing blocks 12. When the side wall of the connecting rod 10 contacts the clamping block 15, press the connecting rod 10 to push the clamping block 15 to retract into the mounting groove 13 until the clamping groove 11 on the side wall of the connecting rod 10 is opposite to the clamping block 15. At this time, the push spring 14 will push the clamping block 15 to clamp into the clamping groove 11. Although the clamping block 15 and the clamping groove 11 are both arc-shaped, under the push of the push spring 14, the connecting rod 10 and the fixing block 12 cannot be easily separated without the application of external force.
