Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire production technology, specifically a wire drawing device for stainless steel wire production. Background Technology

[0002] Stainless steel wire drawing is a metal processing technique and one of the most popular surface treatment technologies in the stainless steel and aluminum products industry today. It is a wire drawing effect treatment applied to stainless steel and aluminum products. However, existing stainless steel wire drawing equipment still has certain shortcomings in subsequent use.

[0003] Chinese patent application number 202121286285.1 discloses a stainless steel wire drawing device. This utility model, by setting a rotating mechanism, has a drawing disc that is rotated and installed inside the entire device. When it is necessary to change the diameter of the drawing hole, the fixing bolt on the top of the drawing disc can be directly removed from the inside of the drawing disc. At this time, the drawing disc can be controlled to rotate inside the second support plate until the drawing hole of the required diameter is rotated to the desired position. Then, the fixing bolt can be screwed back into the inside of the drawing disc to fix it. This device makes the adjustment process of the entire drawing hole very convenient and quick, thus improving the user experience to a certain extent.

[0004] Although the aforementioned patent achieves the wire drawing process for stainless steel wire, the surface dust removal process before wire drawing relies solely on water sprayed from a nozzle. This fails to remove stubborn dust adhering to the stainless steel wire surface, which still affects the final wire drawing quality.

[0005] Chinese patent discloses a stainless steel wire drawing device (application number 202323083214.3). This patented technology is equipped with a stainless steel wire cleaning mechanism, which can facilitate the cleaning of stainless steel wire and has a better cleaning effect. It cleans the stainless steel wire by repeatedly rubbing it with a cleaning roller after it is wetted, thereby cleaning the dirt on the surface of the stainless steel wire and achieving a better effect.

[0006] However, it has certain drawbacks: it uses a cleaning method that involves contacting and rubbing the cleaning roller with the wire surface. Since the cleaning roller can only cover one side of the wire, the surface of the wire away from the cleaning roller (such as the upper surface or non-contact surface) is prone to residual oxide scale, oil stains or particulate impurities due to insufficient friction. Such residues can easily cause problems such as mold wear, scratches on the wire surface or wire breakage during the subsequent wire drawing process, which seriously affects the quality of finished products and processing efficiency.

[0024] Please see Figures 1-3In this embodiment of the present invention, a wire drawing device for stainless steel wire production includes a wire drawing table 1, a wire drawing box 2 fixedly connected to the upper surface of the wire drawing table 1, a wire drawing die head 3 and a wire drawing die head 4 respectively fixedly connected to the left and right sides of the wire drawing box 2, a wire guiding mechanism 5 is provided on the upper surface of the wire drawing table 1 on the left side of the wire drawing box 2, the wire guiding mechanism 5 includes a support plate 6, the lower end of the support plate 6 is fixedly connected to the upper surface of the wire drawing table 1, a plurality of rollers 7 are rotatably connected to the front surface of the support plate 6 from left to right, and a plurality of support bolts 8 are threadedly connected to the upper surface of the support plate 6 from left to right, a support block 9 is rotatably connected to the lower end of the support bolt 8, the support block 9 is slidably connected to the support plate 6, and a roller 10 is rotatably connected to the front end of the support block 9, the roller 10 is located above the rollers 7;

[0025] Drawing die head 1 3 and drawing die head 2 4 are used for the insertion of stainless steel wire 27. Under the action of traction force, stainless steel wire 27 passes through the die hole. Because the diameter of the die hole is smaller than the diameter of the original wire, the material undergoes radial compression and axial extension. The metal flows along the die hole wall and completes the final forming in the sizing zone.

[0026] Roller 7 and roller 10 are used to straighten stainless steel wire 27;

[0027] The support plate 6 has multiple sliding holes from left to right inside, the number of which is equal to that of the support block 9. The support block 9 can move up and down inside the sliding holes.

[0028] Rotating the support bolt 8 can drive the support block 9 to rise and fall, thereby adjusting the distance between roller 1 7 and roller 2 10, which is suitable for stainless steel wire 27 of different specifications.

[0029] exist Figure 1 , Figure 4 and Figure 5In the middle section: A wire cleaning mechanism 11 is provided on the upper surface of the wire drawing table 1 between the wire drawing box 2 and the wire smoothing mechanism 5. The wire cleaning mechanism 11 includes a base 12, the lower end of which is fixedly connected to the upper surface of the wire drawing table 1. A rotating shaft 13 is rotatably connected to the upper surface of the base 12. A gear 14 is fixedly sleeved on the outer surface of the rotating shaft 13. Racks 15 are slidably connected to both the front and rear sides of the upper surface of the base 12 at the rotating shaft 13. The racks 15 are meshed with the gears 14. A fixing plate 16 and an L-shaped plate 17 are fixedly connected to the upper surfaces of the rear rack 15 and the front rack 15, respectively. An elastic pad 18 is fixedly connected to the opposite side surface of the fixing plate 16 and the L-shaped plate 17. The elastic pads 18 fit together. A driving component 19 is provided on the right side surface of the base 12. The driving component 19 includes a horizontal plate 20. The left end of the horizontal plate 20 is fixed to the right side surface of the base 12. A vertical plate 21 is fixed to the upper surface of the horizontal plate 20. A motor 22 is fixed to the rear surface of the vertical plate 21. A turntable 23 is fixed to the output end of the motor 22. A rotating rod 24 is rotatably connected to the outer edge of the front surface of the turntable 23. A rotating rod 25 is rotatably connected to the left end of the rotating rod 24. The left end of the rotating rod 25 is fixed to the right end of the rear rack 15. A slider 26 is movably sleeved on the outer surface of the rotating rod 25. The lower end of the slider 26 is fixed to the upper surface of the horizontal plate 20.

[0030] The elastic pad 18 is made of a wear-resistant and high-temperature resistant polymer elastic material, specifically nitrile rubber or polyurethane rubber. The elastic pad 18 can be glued to the fixing plate 16 and L-shaped plate 17 with industrial adhesive and is replaceable.

[0031] The stainless steel wire 27 passes between two elastic pads 18, which wrap around the outside of the stainless steel wire 27, allowing for a thorough cleaning of the stainless steel wire 27 without any blind spots.

[0032] When gear 14 rotates, the two racks 15 will move relative to each other or in opposite directions.

[0033] The upper surface of the base 12 has protruding parts at both the front and rear ends. The protruding parts are inserted into the entire lower surface of the rack 15 and slidably connected, so that the rack 15 can only move in the left and right direction and will not move in the front and back direction.

[0034] The rotation of turntable 23 drives the rotation rod 24 to move the rotation rod 25 back and forth, thereby driving the rear rack 15 to move back and forth. Under the action of gear 14, the front rack 15 will also move in the left and right direction, thereby driving the fixed plate 16 and L-shaped plate 17 to move repeatedly relative to each other or away from each other, so that the elastic pad 18 cleans the stainless steel wire 27 in a rubbing motion, further improving the cleaning effect.

[0035] The working principle of this utility model is as follows: At the start of operation, the operator first grinds the end of the stainless steel wire 27 into a pointed shape, then passes it sequentially through the gap between roller 7 and roller 10 of the straightening mechanism 5, between the two elastic pads 18 of the wire clearing mechanism 11, then through the die holes of the drawing die head 3 and the drawing die head 4, and finally connects it to the traction device. After threading is completed, the equipment is started, and the traction device drives the wire to move at a uniform speed. At this time, roller 7 and roller 10 in the straightening mechanism 5 continuously clamp the wire for rolling straightening. The operator can adjust the distance between them in advance by rotating the support bolt 8 to accommodate changes in wire diameter. In the synchronously operating wire cleaning mechanism 11, the motor 22 drives the turntable 23 to rotate, which drives the rear rack 15 to reciprocate left and right through the first rotating rod 24 and the second rotating rod 25. The gear 14 transmits this motion in the opposite direction to the front rack 15, so that the elastic pads 18 on the fixed plate 16 and the L-shaped plate 17 repeatedly rub the surface of the wire like a "washboard" to thoroughly remove oxide scale and impurities. After cleaning and straightening, the wire enters the wire drawing box 2 and passes through the wire drawing die head 3 and the wire drawing die head 4 with gradually decreasing diameters in sequence. Under the pressure of the die holes, it undergoes plastic deformation and finally forms a stainless steel wire 27 that meets the specifications.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
