Technical Field

[0001] This utility model belongs to the field of grinding needle technology, and specifically relates to a grinding device for wire drawing die grinding needles. Background Technology

[0002] Wire drawing dies are widely used in the production of metal wires, tubes, and other wires. Their key function is to achieve precise stretching and shaping of materials through the cooperation of the die and drawing needles. During the wire drawing process, the grinding needle, as a crucial auxiliary tool, plays a vital role in maintaining the smoothness of the die surface, reducing friction, and ensuring production stability. However, with extended production cycles and increased usage, the tip and surface of the grinding needle gradually wear down, directly affecting the processing accuracy and production efficiency of the wire drawing die.

[0003] The grinding technology for grinding needles mostly uses manual or semi-automatic equipment for surface treatment. These traditional grinding techniques cannot ensure that all parts of the grinding needle are ground evenly, especially the needle tip, which is prone to severe wear. The height and angle of the grinding needle are also difficult to adjust precisely, resulting in unsatisfactory grinding results. To address this, we have designed a grinding device for wire drawing die grinding needles to provide an alternative technical solution to the above-mentioned technical problems.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-8 A wire drawing die grinding needle polishing device includes a first rectangular support frame 1 and a second rectangular support frame 2. Both ends of the top of the first rectangular support frame 1 are provided with transverse rotating rollers 5. A vertical support plate 3 is fixed to one side of the top of the first rectangular support frame 1. A first drive motor 4 is bolted to one side of the vertical support plate 3. The output end of the first drive motor 4 is fixedly connected to one of the transverse rotating rollers 5. Sandpaper belts 6 are sleeved on the outer sides of the two transverse rotating rollers 5.

[0025] The top of the second rectangular support frame 2 is provided with a movable rectangular frame 7, the bottom of the rectangular frame 7 is provided with a vertical lifting plate 13, and multiple longitudinal grinding needles 15 are evenly distributed at the bottom of the vertical lifting plate 13.

[0026] The first rectangular support frame 1 has a slidably connected debris collection box 9 inside. Both ends of the bottom of the debris collection box 9 are fixed with rectangular sliders. The first rectangular support frame 1 has a rectangular groove adapted to the rectangular slider inside. The first rectangular support frame 1 and the debris collection box 9 are slidably connected by the rectangular slider and the rectangular groove. The debris collection box 9 can slide inside the first rectangular support frame 1 by the rectangular slider and the rectangular groove. The debris collection box 9 is located at the bottom of the sandpaper belt 6 so that the debris after grinding by the longitudinal grinding needle 15 can be collected into the interior of the debris collection box 9.

[0027] Here, the operation of the first drive motor 4 causes one of the transverse rotating rollers 5 to rotate, which in turn causes the sandpaper belt 6 to rotate, so that the sandpaper belt 6 can better polish the longitudinal grinding needle 15. The debris from the longitudinal grinding needle 15 can fall into the front part of the debris collection box 9, so that the debris can be collected. By pulling the debris collection box 9, the debris collection box 9 can be moved out of the interior of the first rectangular support frame 1, so that the debris inside the debris collection box 9 can be transferred.

[0028] A rectangular support plate 10 is fixed at one end of the top of the second rectangular support frame 2. A second hydraulic cylinder 11 is fixed inside the rectangular support plate 10. The output end of the second hydraulic cylinder 11 is fixedly connected to the rectangular frame 7. A transverse rectangular support frame 12 is fixed at one end of the rectangular support plate 10 and at the bottom of the rectangular frame 7. The rectangular frame 7 and the transverse rectangular support frame 12 are slidably connected.

[0029] Dovetail sliders are fixed on both sides of the bottom of the rectangular frame 7. The interior of the transverse rectangular support frame 12 is provided with a dovetail groove that matches the dovetail slider. The rectangular frame 7 and the transverse rectangular support frame 12 are slidably connected by the dovetail slider and the dovetail groove. The dovetail slider and the dovetail groove allow the rectangular frame 7 to slide laterally on the top of the transverse rectangular support frame 12. The sliding of the rectangular frame 7 allows the longitudinal grinding needle 15 to slide.

[0030] Both ends of the rectangular frame 7 are fixed with a first hydraulic cylinder 8. The output end of the first hydraulic cylinder 8 is connected to the vertical lifting plate 13. The bottom of the vertical lifting plate 13 is fixed with a horizontal fixing block 14. Multiple longitudinal grinding needles 15 are located inside the horizontal fixing block 14 and are rotatably connected to the horizontal fixing block 14. The output end of the first hydraulic cylinder 8 is provided with a rotating mechanism for rotating the vertical lifting plate 13.

[0031] Here, the operation of the second hydraulic cylinder 11 allows the rectangular frame 7 to slide laterally on the outside of the transverse rectangular support frame 12, thereby allowing the vertical lifting plate 13 to slide laterally. The movement of the vertical lifting plate 13 allows the longitudinal grinding needle 15 to move, so that the longitudinal grinding needle 15 can move laterally when grinding at the bottom of the sandpaper belt 6.

[0032] The rotating mechanism includes an L-shaped fixing block 16. One end of the output end of the first hydraulic cylinder 8 is fixed with the L-shaped fixing block 16. The third hydraulic cylinder 17 is fixed inside the L-shaped fixing block 16. The output end of the third hydraulic cylinder 17 is rotatably connected to a rectangular rotating plate 18 via a pin. A rectangular transmission plate 19 is rotatably connected to one side of the rectangular rotating plate 18. A transverse rotating rod 20 is fixed inside the rectangular transmission plate 19. The transverse rotating rod 20 passes through the interior of the first hydraulic cylinder 8 and is rotatably connected to the first hydraulic cylinder 8 via a bearing. Both ends of the output end of the first hydraulic cylinder 8 are provided with arc-shaped fixing plates 21. The bottom of the arc-shaped fixing plates 21 is fixedly connected to the vertical lifting plate 13. The transverse rotating rod 20 is fixedly connected to the arc-shaped fixing plates 21, thereby enabling the operation of the third hydraulic cylinder 17 to allow the vertical lifting plate 13 to rotate around the transverse rotating rod 20 as the center.

[0033] Here, the operation of the rectangular rotating plate 18, through the rectangular rotating plate 18 and the rectangular transmission plate 19, enables the rectangular transmission plate 19 to drive the horizontal rotating rod 20 to rotate. Through the fixed connection between the horizontal rotating rod 20 and the arc-shaped fixed plate 21, the vertical lifting plate 13 can rotate, so that the longitudinal grinding needle 15 can rotate with the vertical lifting plate 13, so that the tip of the longitudinal grinding needle 15 can be ground.

[0034] Working principle: The operation of the first drive motor 4 causes one of the transverse rotating rollers 5 to rotate, which in turn causes the sandpaper belt 6 to rotate, so that the sandpaper belt 6 can better polish the longitudinal grinding needle 15. The debris from the longitudinal grinding needle 15 can fall into the front part of the debris collection box 9, so that the debris can be collected. By pulling the debris collection box 9, the debris collection box 9 can be moved out of the interior of the first rectangular support frame 1, so that the debris inside the debris collection box 9 can be transferred.

[0035] The operation of the second hydraulic cylinder 11 allows the rectangular frame 7 to slide laterally on the outside of the transverse rectangular support frame 12, thereby allowing the vertical lifting plate 13 to slide laterally. The movement of the vertical lifting plate 13 allows the longitudinal grinding needle 15 to move, so that the longitudinal grinding needle 15 can move laterally when grinding at the bottom of the sandpaper belt 6.

[0036] The operation of the rectangular rotating plate 18, through the rectangular rotating plate 18 and the rectangular transmission plate 19, enables the rectangular transmission plate 19 to drive the horizontal rotating rod 20 to rotate. Through the fixed connection between the horizontal rotating rod 20 and the arc-shaped fixed plate 21, the vertical lifting plate 13 can rotate, so that the longitudinal grinding needle 15 can rotate with the vertical lifting plate 13, so that the tip of the longitudinal grinding needle 15 can be ground. When the longitudinal grinding needle 15 rotates, the periphery of the longitudinal grinding needle 15 can be ground.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
