Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, specifically a compact, high-power, air-cooled metal wire drawing machine. Background Technology

[0002] Metal wire drawing machines are essential processing equipment in many industries such as wire and cable, hardware products, and aerospace. Their working principle is to use a traction mechanism to provide constant tension, driving large-diameter, thick-gauge metal wires to forcefully pass through drawing dies with progressively decreasing apertures. Through the extrusion and shaping action of the dies, the cross-section of the metal wire is uniformly compressed and extended. Without changing the physical and chemical properties of the metal material, the wire diameter is gradually reduced, the roundness and surface flatness of the wire are optimized, and the internal metallographic structure of the metal is refined.

[0003] When using a traditional metal wire drawing machine, the metal wire passes through the drawing die at high speed for extrusion and drawing. During this process, the metal undergoes plastic deformation, and the high-speed friction between the wire and the inner wall of the die generates a large amount of heat, causing the temperature of the wire and the die to rise sharply. Traditional wire drawing machines often use external air-cooled fans or other cooling methods. These methods result in cumbersome equipment structures, large installation space requirements, poor overall compactness, and poor cooling targeting, failing to accurately act on the core area of ​​frictional heat exchange between the wire and the die. Summary of the Invention

[0004] The purpose of this invention is to provide a compact, high-power, air-cooled metal drawing machine to solve the problem of inconvenience in using existing metal drawing machines.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A compact, high-power, air-cooled metal drawing machine, including a protective housing, and further comprising: The wire drawing die has a protective box with a support frame inside. The support frame has multiple support blocks, and the support blocks have support plates. The support plates have pressure plates, and the pressure plates have a drive rod and a die box outside. The drive rod has a rotating disk outside, and pressure blocks are provided on the sides of the two rotating disks that are close to each other. The die box contains the wire drawing die, and the outside of the wire drawing die has multiple heat dissipation slots. The die box has a water inlet pipe outside, and a cooling pipe is fitted around the outside of the wire drawing die. One end of the water inlet pipe is connected to the cooling pipe. A rotating fan is provided. A cooling box is provided outside the wire drawing die. A fixed plate is provided inside the cooling box. A fixed plate is provided on the fixed plate. A rotating fan is provided on the fixed plate. A rotating plate is provided on the fixed plate. A rotating shaft is provided at both ends of the rotating plate. Mounting brackets are provided on both sides of the outside of the protective box. A rotating shaft is provided on the mounting bracket. A guide wheel is provided on the rotating shaft. The transmission mechanism is located between the rotating plate and the rotating fan, and cools the metal wire passing through the mold box by driving the rotating fan to rotate.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative embodiment: the transmission mechanism includes a transmission belt, a rotating wheel, and a limiting rod. A rotating wheel and a worm are respectively provided on the two rotating shafts. A worm wheel that meshes with the worm is provided on the fixed plate. The worm wheel is connected to a rotating fan. A limiting rod is provided on the fixed plate. A transmission groove is opened on the rotating plate. The limiting rod passes through the transmission groove and slides with it. A transmission belt is provided between the two rotating shafts.

[0007] In one alternative: a water pump is provided on the support plate, the input end of the water pump is connected to the drive rod, and the water pump is provided with an inlet pipe and an inlet tube.

[0008] In one alternative: the support frame is provided with a sliding groove, the support block is slidably disposed inside the sliding groove, and the pressure plate is provided with a scissor bar.

[0009] In one alternative: a slider is provided outside the sliding groove, the center position of the scissor bar is rotatably connected to the slider, and a guide rail is provided at the center position of the support frame.

[0010] In one alternative: a movable block is provided on the guide rail, one end of the scissor bar is connected to the movable block, a transmission block is provided on the movable block, and a screw is provided between the two transmission blocks.

[0011] In one alternative: the protective box is provided with an installation plate on the outside, and the mold box is provided with a drain pipe on the outside.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The compact, high-power air-cooled metal wire drawing machine operates through a metal belt-driven air-cooling structure. The metal wire is fed in and the friction drives the transmission wheel to rotate. The transmission wheel, along with the transmission belt and worm gear, drives the rotating fan to deliver air. This eliminates the need for an additional drive motor, achieving air-cooling and heat dissipation, reducing overall energy consumption, and improving the machine's compactness and integration. It is suitable for use in confined spaces. A water pump drives cooling water to circulate along the cooling pipes on the outside of the wire drawing die, providing enveloping water-cooling to the high-temperature core friction area of ​​the die. This quickly removes the heat accumulated in the die and effectively reduces wear and tear caused by high temperatures. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0021] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0022] like Figure 1-6 As shown, a compact, high-power air-cooled metal wire drawing machine according to an embodiment of the present invention includes a protective box 1, and further includes: The wire drawing die 19 has a support frame 5 fixedly installed inside the protective box 1. Multiple support blocks 10 are slidably mounted on the support frame 5. Support plates 7 are mounted on the support blocks 10, and pressure plates 11 are mounted on the support plates 7. A drive rod 9 and a die box 13 are mounted outside the pressure plates 11. A cover plate 8 is mounted on the top of the die box 13. When the two sets of pressure plates 11 move relative to each other, they can squeeze, position, and clamp the multiple die boxes 13, while simultaneously releasing the clamping limit, enabling quick assembly and disassembly of the die boxes 13. This facilitates the disassembly and cleaning of the internal dies by the operators. For maintenance, repair, and replacement, a rotating disk 24 is provided on the outside of the drive rod 9. A pressure block is provided on one side of each rotating disk 24 that is close to each other. The drive rod 9 drives the rotating disk 24 to rotate, and the two rotating disks 24 clamp the metal wire body 6 through the pressure blocks. The metal wire body 6 is pulled forward at a constant speed by rotational friction, achieving continuous feeding of the metal wire. The metal wire body 6 is parallel to the support frame 5, and the feeding process is smooth and without deviation. A wire drawing die 19 is provided inside the die box 13. The wire drawing die 19 is fixed inside the die box 13 by fastening bolts. (The last sentence appears to be incomplete and possibly refers to a different process.) The wire drawing die 19 allows for rapid replacement with different specifications to meet processing needs. The die 19 employs a structure with different diameter holes at both ends; the inlet hole diameter is larger than the outlet hole diameter. Under traction, the metal wire enters through the larger diameter end and exits through the smaller diameter end. The gradually changing hole structure of the die uniformly compresses and shapes the outer wall of the metal wire, compressing its cross-sectional area, refining its dimensions, and simultaneously smoothing the surface flatness of the wire, thus completing the metal wire drawing finishing process. The wire drawing die 19 has multiple heat dissipation grooves 191 on its exterior, and the die box 13 has a water inlet pipe 14 on its exterior. The wire drawing die 19 is fitted with a cooling pipe 18. One end of the water inlet pipe 14 is connected to the cooling pipe 18. A cooling water storage chamber is provided at the bottom of the inner cavity of the protective box 1. Cooling water is introduced into the cooling pipe 18 through the water inlet pipe 14. The cooling water flows along the outer wall of the wire drawing die 19 and flows through multiple die boxes 13 arranged in series with the wire drawing die 19. It carries away the heat generated by the friction between the die and the metal wire during the wire drawing operation. After the heat exchange is completed, the cooling water flows back to the storage chamber at the bottom of the protective box 1 through the drain pipe 12 to form a circulating water cooling circuit and realize continuous circulating water cooling. A rotating fan 34 is mounted on the outside of the wire drawing die 19, and a cooling box 20 is provided outside the cooling box 20. A fixing plate 30 is provided inside the cooling box 20, and a fixing disk 31 is provided on the fixing plate 30. A rotating fan 34 is mounted on the fixing disk 31. When the rotating fan 34 is working, it introduces outside air into the cooling box 20. The airflow passes through the wire perforation area of ​​the wire drawing die 19 and blows and cools the moving metal wire body 6, removing the high temperature of friction on the surface of the metal wire. The air-cooling structure and the circulating water-cooling structure work together to form a dual heat dissipation system of water-cooled die and air-cooled wire, improving the overall heat dissipation and cooling effect. A rotating plate 32 is provided on the fixing disk 31. Both ends are provided with rotating shafts 37. One end of the rotating plate 32 is provided with a rotating wheel 33 through the corresponding rotating shaft 37. The wheel surface of the rotating wheel 33 is in close contact with the surface of the metal wire body 6. During the continuous feeding of the metal wire body 6, the rotating wheel 33 is driven to rotate by friction, which in turn drives the rotating plate 32 and the fan transmission structure to operate. No additional motor drive is required. The fan rotation is achieved by relying on the power of the wire drawing operation itself, realizing the linkage effect of heat dissipation during operation and fan stoppage when the machine stops. The protective box 1 is provided with mounting brackets 2 on both sides. The mounting brackets 2 are provided with rotating shafts 3. The rotating shafts 3 are provided with guide wheels 4 to guide the metal wire body 6 during the feeding process. The transmission mechanism is located between the rotating plate 32 and the rotating fan 34, and cools the metal wire passing through the mold box 13 by driving the rotating fan 34 to rotate.

[0023] like Figure 1-6 As shown in the preferred embodiment of the present invention, the transmission mechanism includes a transmission belt 39, a rotating wheel 33, and a limiting rod 38. Two rotating shafts 37 are respectively provided with a rotating wheel 33 and a worm gear 36. A worm wheel 35 meshing with the worm gear 36 is provided on the fixed disk 31. The worm wheel 35 is connected to the rotating fan 34. A limiting rod 38 is provided on the fixed plate 30. A transmission groove 321 is opened on the rotating plate 32. The limiting rod 38 passes through the transmission groove 321 and slides with it. A transmission belt 39 is provided between the two rotating shafts 37. During the continuous feeding of the metal wire body 6, the rotating wheel 33 is driven to rotate by friction. The rotating wheel 33 drives the other rotating shaft 37 and the worm gear 36 to rotate via the transmission belt 39. The worm gear 36 drives the worm wheel 35 to rotate through the worm wheel meshing, thereby driving the rotating fan 34 to operate.

[0024] like Figure 1 As shown, in a preferred embodiment of the present invention, a water pump 15 is provided on the support plate 7. The input end of the water pump 15 is connected to the drive rod 9. The water pump 15 is provided with an inlet pipe 16 and an inlet pipe 14. The drive rod 9 drives the water pump 15 to operate after being reduced in speed by a reducer, thereby providing power for the circulation of cooling water.

[0025] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the support frame 5 is provided with a sliding groove 501, the support block 10 is slidably disposed inside the sliding groove 201, and the pressure plate 11 is provided with a scissor bar 27. The pressure plate 11 is rotatably connected to one end of the scissor bar 27 through a rotating shaft 23.

[0026] like Figure 1-2 As shown, in a preferred embodiment of the present invention, a slider 26 is provided on the outside of the sliding groove 201, the center position of the scissor bar 27 is rotatably connected to the slider 26, and a guide rail 25 is provided at the center position of the support frame 5.

[0027] like Figure 1-4 As shown, in a preferred embodiment of the present invention, a movable block 28 is provided on the guide rail 25, one end of the scissor bar 27 is connected to the movable block 28, a transmission block 29 is provided on the movable block 28, and a screw 17 is provided between the two transmission blocks 29. The screw 17 drives the two movable blocks 28 to move closer or further away from each other along the guide rail 25, thereby driving the scissor bar 27 to complete the opening and closing action. The two sets of pressure plates 11 move relative to each other, realizing the extrusion, positioning, clamping and rapid release of multiple mold boxes 13.

[0028] like Figure 1 As shown, in a preferred embodiment of the present invention, the protective box 1 is provided with an mounting plate 21 on the outside, and the mold box 13 is provided with a drain pipe 12 on the outside.

[0029] The above embodiments of the present invention provide a compact, high-power air-cooled metal wire drawing machine. A wire drawing die 19 with a corresponding aperture specification is selected, and the wire drawing die 19 is fixedly installed inside the die box 13 by fastening bolts to complete the die pre-assembly. The screw 17 is rotated, and the scissor fork 27 unfolds or retracts, causing the pressure plates 11 on both sides to move closer or further apart. The clamping distance is adjusted according to the installation size of the die box 13 to complete the alignment and position calibration of multiple sets of die boxes 13. The metal wire body 6 to be processed passes sequentially around the guide wheels 4 on the mounting brackets 2 on both sides of the protective box 1, which horizontally limit the metal wire body 6, keeping it horizontal as it passes through the interior of the protective box 1. An appropriate amount of cooling water is injected into the liquid storage chamber at the bottom of the protective box 1. The drive rod 9 drives the water pump 15 to operate synchronously through the reducer. The water pump 15 draws the cooling water from the liquid storage chamber through the water inlet pipe 16 and delivers it to the cooling pipe 18 on the outside of the wire drawing die 19 through the water inlet pipe 14. The cooling water flows along the outer wall of the wire drawing die 19, ensuring that the wire drawing die is at a normal temperature and avoiding high-temperature heat accumulation during processing. The drive rod 9 drives the rotating disk 24 to rotate, clamping the metal wire body 6 and pulling it forward at a uniform speed. The rotating wheel 33 rotates, driving the rotating fan 34 to operate, providing precise air cooling for the wire.
