Description

Technical Field

[0001] The utility model belongs to the technical field of wire drawing devices, and in particular relates to a wire drawing device for metal wires. Background Art

[0002] Wire drawing is a crucial step in the processing of metal wire, stretching it to achieve the desired diameter and strength. However, during the drawing process, the surface of the metal wire often suffers from scratches and oxidation due to friction and stretching. This not only affects the wire's appearance but can also reduce its performance. To address these issues, the wire is typically oiled, dried, and reeled after drawing.

[0003] Traditional metal wire drawing equipment has numerous shortcomings in terms of oiling, drying, and winding. For example, oiling mechanisms often rely on a simple brushing or immersion method, which not only consumes a lot of oil but also results in uneven oil application, easily leading to oil spots or excessively thick oil film on the wire surface. Drying mechanisms typically use a fixed hot air drying method, unable to adjust the drying temperature and air speed according to the actual conditions of the wire, resulting in unsatisfactory drying results. Winding mechanisms can also suffer from unstable winding tension and the wire tends to become loose or tangled.

[0004] Furthermore, traditional wire drawing equipment is often structurally simple and lacks flexibility, making it unable to meet the processing needs of metal wires of different specifications and materials. Furthermore, equipment maintenance and upkeep are difficult, increasing production costs and downtime. Utility Model Content

The sliding piece 39 is slidably connected to the inside of one of the helical grooves 36 on the outer side of the screw rod 35.

[0056] A first guide wheel 40 is rotatably arranged on the upper end face of the moving seat 38. The axis of the first guide wheel 40 is horizontally arranged in the left-right direction, and a V-shaped groove is arranged in the middle of the outer cylindrical surface of the first guide wheel 40. A horizontal support plate is fixedly arranged in the middle of the upper end of the rear end face of the moving seat 38.

The axis of the second guide wheel 41 is horizontally arranged in the left-right direction, and a V-shaped groove is arranged in the middle of the outer cylindrical surface of the second guide wheel 41.

[0057] A winding roller 12 is rotatably mounted between the rear ends of the left and right sidewalls of the second fixed frame 8. The axis of the winding roller 12 is horizontally arranged in the left-right direction, and the left and right ends of the winding roller 12's shaft are rotatably connected to the left and right sidewalls of the second fixed frame 8, respectively. A synchronous belt drive mechanism is mounted within the right sidewall of the second fixed frame 8, between the output shaft of the drive motor 37 and the right end of the winding roller 12's shaft. As the drive motor 37 rotates, it drives the winding roller 12 via the synchronous belt drive mechanism.

[0058] The working principle of this utility model is:

[0059] When the metal wire needs to be drawn, the metal wire is passed through the drawing machine in sequence, then passed around the oiling roller 7 from the bottom to the back, passed through the docked drying shell 9 backward, passed around the first guide wheel 40 and the second guide wheel 41 from the top to the back, and finally fixedly wound on the winding roller 12.

[0060] The drive motor 37 then drives the screw 35 to rotate, which in turn simultaneously drives the take-up roller 12 via a synchronous belt drive mechanism. The take-up roller 12 tightens the wire and gradually winds it around it. As the tightened wire passes over the oiling roller 7, it drives the oiling roller 7 to rotate, which in turn drives the driving gear 18. The meshing of the driving gear 18 and the driven gear 17 drives the oiling roller 14 to rotate synchronously. When the oil dripping roller 14 rotates, the lubricating oil inside the oil dripping box 6 enters the oil dripping groove 15 of the oil dripping roller 14. As the oil dripping roller 14 continues to rotate, the oil dripping groove 15 filled with the lubricating oil rotates to the connecting groove 13 of the oil dripping box 6. In this way, the lubricating oil inside the oil dripping groove 15 drips from the connecting groove 13 onto the oil coating roller 7. The oil coating roller 7 applies the lubricating oil to the metal wire. As the metal wire continues to move backward, the lubricating oil inside the oil dripping box 6 continuously drips onto the oil coating roller 7 through the oil dripping roller 14.

[0061] The lubricated metal wire passes through two joined cleaning blocks 29, which wipe away any remaining lubricant on the outside of the metal wire. After wiping, the metal wire enters the large-diameter section 27 of the drying housing 9. The hot air blower 10 delivers hot air to the hot air distribution box 31 via the hot air inlet pipe 33. The hot air distribution box 31 then delivers hot air to the large-diameter section 27 of the drying housing 9 via the hot air inlet pipe 33, thereby drying the wiped metal material.

[0062] The oil collecting tank 19 can collect the lubricating oil dripping from the metal wire.

[0063] Because the sliding piece 39 on the movable seat 38 is slidably connected to the spiral groove 36 of the screw 35, the screw 35 drives the sliding piece 39 to slide inside the spiral groove 36 when it rotates. The sliding piece 39 drives the movable seat 38 to slide on the second guide rod 34. The sliding movable seat 38 guides the metal wire through the first guide wheel 40 and the second guide wheel 41, so that the metal wire is evenly wound on the winding roller 12. When the sliding piece 39 slides to the end of the spiral groove 36, because the same ends of the two spiral grooves 36 are transitionally connected, the sliding piece 39 can smoothly enter the interior of the other spiral groove 36, so that the sliding piece 39 drives the movable seat 38 to start sliding in the opposite direction. The movable seat 38 drives the metal wire to be evenly wound on the winding roller 12 in the other direction. This cycle is repeated continuously, so that all the metal wires are evenly wound and fixed on the winding roller 12.

[0064] After the metal wire is drawn and wound, the hand wheel 22 is turned to move the left sliding seat 23 and the right sliding seat 24 away from each other, so that the cleaning blocks 29 inside the left shell 25 and the right shell 26 can be replaced, and the inside of the drying shell 9 can also be cleaned.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
