Description

Technical Field

[0001] This utility model relates to the field of wire drawing die technology, and in particular to a small-diameter diamond-coated wire drawing die that is easy to adjust. Background Technology

[0002] Diamond-coated wire drawing dies are precision tools with a diamond (natural or artificial) coating on the surface of traditional wire drawing dies. They are mainly used for the drawing of metal wires (such as copper, aluminum, steel, tungsten, etc.). Through the super-hard properties of the diamond coating, the wear resistance, processing accuracy and life of the die are significantly improved, making it especially suitable for the production of high-precision and high-strength wires.

[0003] Chinese patent discloses a micro-aperture diamond-coated wire drawing die (authorization announcement number CN217798128U). This patented technology includes a wire drawing mechanism with a fixing mechanism installed around it. The wire drawing mechanism includes a die body, a connecting body installed at the front end of the die body, a feed inlet extending through the front and rear ends of the connecting body, a compression port extending through the front end of the die body and located behind the feed inlet, a sizing port extending through the rear end of the compression port, a diamond layer on the inner wall of the sizing port, a pressure relief port extending through the rear end of the sizing port, and a discharge port extending through the rear end of the die body and located behind the pressure relief port. An installation groove is provided near the edge of the front end of the die body. This micro-aperture diamond-coated wire drawing die is easy to install and disassemble, facilitates cleaning of blockages, improves work efficiency, and helps reduce the heat generated during wire drawing, thus extending the service life of the die body.

[0004] However, this patent still has shortcomings. While it is convenient to disassemble and clear blockages, when the production process needs to be adjusted to directly draw wires to other radii, the mold needs to be replaced. This mold replacement requires personnel to store, retrieve, transport, and assemble the mold, resulting in a considerable preparation time. The flexibility and convenience in handling changes to the production process need to be improved. Therefore, those skilled in the art have provided an easily adjustable small-aperture diamond-coated wire drawing mold to solve the problems mentioned in the background section. Utility Model Content

[0005] Technical solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an easily adjustable small-diameter diamond-coated wire drawing die, comprising a mounting box, a die ring, a rotating ring, a ring seat, an adjusting plate, and a fixing ring. The mounting box contains a guide rail and a ring seat. A slider is slidably mounted on the upper end of the guide rail. An adjusting plate is mounted on the upper end of the slider. Die rings are evenly distributed on the front side of the adjusting plate. A diamond-coated wire drawing die body with progressively decreasing internal die holes is embedded inside each die ring. A fixing ring is fixed inside the mounting box and suspended within the ring seat. A rotating ring is sleeved on the outside of the fixing ring. The inner wall of the rotating ring is provided with extrusion blocks arranged in a circular array with gradually increasing inner wall thickness. The inner wall of the fixed ring is provided with three springs that are evenly distributed. One end of each spring is provided with a support ring. One end of each support ring is provided with a positioning block. The outer wall of the mold ring is provided with positioning grooves that are arranged in a ring array and are inserted and assembled with the positioning blocks. One end of the rotating ring is provided with a worm gear. A rotating shaft is rotatably installed inside the mounting box. A worm gear that meshes with the worm gear is sleeved on the outer wall of the rotating shaft. A pull rope with one end fixedly connected to the outer wall of the rotating shaft and slidably installed with the rear end of the mounting box is wound on the outer wall of the rotating shaft. A disc spring with its inner and outer ends connected to the rotating shaft and the mounting box respectively is sleeved on the outer side of the rotating shaft. A spring that is symmetrically distributed between the mold ring and the adjusting plate is provided.

[0008] Furthermore, a guide rod connected to the mold ring is slidably installed inside the adjusting plate, a second sliding sleeve is embedded inside the front end of the mounting box, a pull rod is slidably installed inside the second sliding sleeve, a pressure ring is provided at one end of the pull rod located behind the guide rod, and a pull ring is provided at the other end of the pull rod located outside the mounting box.

[0009] Specifically, when the mold ring is elastically supported by the spring, the guide rod slides inside the adjusting plate to guide the spring and prevent it from shifting outward. The gripping ring facilitates the application of pulling force to the pull rod, and the pull rod drives the rear end of the guide rod to be squeezed.

[0010] Furthermore, the inner wall of the mounting box is provided with a guide plate, one end of the pull rod is slidably inserted into the inside of the guide plate, a second support ring is sleeved on the outer wall of the pull rod, and a second spring sleeved on the outside of the pull rod is provided between the second support ring and the guide plate;

[0011] Specifically, the pull rod is slidably supported by the guide plate. When the pull rod moves, it applies a compressive force to the spring through the second support ring, which causes the pull rod to automatically reset after it relaxes.

[0012] Furthermore, the adjusting plate has a stroke groove inside that corresponds to the internal diameter of the diamond-coated wire drawing die body, and the mounting box has wire feeding holes at both the front and rear ends that correspond to the stroke groove. One end of the mounting box has an operation port.

[0013] Specifically, the wire that reduces the aperture moves inside the adjustment plate and mounting box through the stroke groove and stroke port, while the operation port adjusts the position of the slider as it slides on the outer wall of the guide rail.

[0014] Furthermore, a sliding sleeve 1 arranged in a ring array is embedded in the inner wall of the fixed ring. An installation post is slidably installed inside the sliding sleeve 1. One end of the installation post is connected to the support ring 1. A ball bearing is embedded in the end of the installation post that is opposite to the pressing block.

[0015] Specifically, the mounting column is slidably supported inside the fixed ring by a sliding sleeve, and the ball bearings prevent the mounting column from directly contacting the extrusion block, thereby reducing friction and resistance when the extrusion block passes through.

[0016] Furthermore, the outer wall of the rotating shaft is fitted with symmetrically distributed limiting wheels located on the upper and lower sides of the pull rope in the winding state, the outer wall of the rotating ring is fitted with a ring rail rotatably installed inside the ring seat, and the pull rope is provided with a pull handle at one end located outside the mounting box.

[0017] Specifically, the rotating ring is supported for rotation within the ring seat via the ring rail. The pull handle facilitates the application of pulling force to the rope, and the limit wheel limits the winding of the rope to prevent it from becoming tangled during winding.

[0018] Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention involves elastically mounting diamond-coated wire drawing dies of different apertures on the front side of an adjusting plate. The adjusting plate is slidably adjusted, and the corresponding diamond-coated wire drawing die body is pushed into the mounting ring. It is then fixed by positioning blocks arranged in a ring array and elastically supported within the mounting ring. The positioning blocks are triggered by a pressing block, and a pull rope pulls the rotating shaft. The rotational force of the shaft causes the worm gear and worm wheel to engage, unfolding the positioning blocks. Subsequently, the tension of the pull rope contacting the positioning blocks is relaxed. The positioning blocks' own elastic force and the pressing force generated by the reverse rotation of the worm wheel cause the pressing blocks to rotate, causing the positioning blocks to insert into the positioning groove inside the die ring. This positions the diamond-coated wire drawing die that has entered the mounting ring. When the shaft is no longer pressed, the elastic force of the coil spring causes the shaft and worm gear to rotate in opposite directions, achieving automatic reset. The replacement of the diamond-coated wire drawing die is completed behind the sliding adjusting plate with a simple push and pull, making aperture adjustment of the diamond-coated wire drawing die convenient and allowing for easy replacement to adapt to changes in production processes, thus improving flexibility.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Example

[0036] Please see Figure 1-6 As shown, this embodiment is an easily adjustable small-aperture diamond-coated wire drawing die, including a mounting box 1, a die ring 7, a rotating ring 8, a ring seat 9, an adjusting plate 10, and a fixing ring 25. The mounting box 1 is equipped with a guide rail 6 and a ring seat 9. A slider 11 is slidably mounted on the upper end of the guide rail 6. An adjusting plate 10 is mounted on the upper end of the slider 11. Die rings 7 are evenly distributed on the front side of the adjusting plate 10. A diamond-coated wire drawing die body 26 with progressively decreasing internal die holes is embedded inside the die rings 7. A fixing ring 25 is fixed inside the mounting box 1 and suspended inside the ring seat 9. A rotating ring 8 is sleeved on the outside of the fixing ring 25. The inner wall of the rotating ring 8 is provided with extrusion blocks 21 arranged in a ring array with gradually increasing inner wall thickness. The fixing ring 25... The inner wall of the mold ring 7 is provided with equidistantly distributed springs 37. One end of each spring 37 is provided with a support ring 28. One end of each support ring 28 is provided with a positioning block 29. The outer wall of the mold ring 7 is provided with positioning grooves 14 arranged in a ring array and inserted into the positioning block 29. One end of the rotating ring 8 is provided with a worm gear 15. The mounting box 1 is rotatably mounted with a rotating shaft 20. The outer wall of the rotating shaft 20 is sleeved with a worm 17 that meshes with the worm gear 15. The outer wall of the rotating shaft 20 is wound with a pull rope 13, one end of which is fixedly connected to the outer wall of the rotating shaft 20 and slidably mounted with the rear end of the mounting box 1. The outer side of the rotating shaft 20 is sleeved with a disc spring 18 whose inner and outer ends are respectively connected to the rotating shaft 20 and the mounting box 1. The mold ring 7 and the adjusting plate 10 are provided with symmetrically distributed springs 23.

[0037] A guide rod 24 connected to the mold ring 7 is slidably installed inside the adjusting plate 10. A sliding sleeve 36 is embedded inside the front end of the mounting box 1. A pull rod 3 is slidably installed inside the sliding sleeve 36. A pressure ring 32 located behind the guide rod 24 is provided at one end of the pull rod 3 located in the mounting box 1. A pull ring 4 is provided at the other end of the pull rod 3 located outside the mounting box 1.

[0038] The inner wall of the mounting box 1 is provided with a guide plate 35. One end of the pull rod 3 is slidably inserted into the inside of the guide plate 35. A support ring 33 is sleeved on the outer wall of the pull rod 3. A spring 34 is sleeved on the outside of the pull rod 3 between the support ring 33 and the guide plate 35.

[0039] The adjustment plate 10 has a stroke groove 22 inside that corresponds to the internal diameter of the diamond-coated wire drawing die body 26. The mounting box 1 has wire feeding holes 5 at both the front and rear ends that correspond to the stroke groove 22. The mounting box 1 has an operation port 2 at one end.

[0040] A sliding sleeve 27 arranged in a ring array is embedded in the inner wall of the fixed ring 25. A mounting post 30 is slidably installed inside the sliding sleeve 27. One end of the mounting post 30 is connected to the support ring 28. A ball bearing 31 is embedded in the end of the mounting post 30 that is opposite to the pressing block 21.

[0041] The outer wall of the rotating shaft 20 is fitted with symmetrically distributed limit wheels 19 on the upper and lower sides of the pull rope 13 in the winding state. The outer wall of the rotating ring 8 is fitted with a ring rail 16 that is rotatably installed inside the ring seat 9. The pull rope 13 is provided with a pull handle 12 at one end outside the mounting box 1.

[0042] In this embodiment, the adjusting plate 10 is slid laterally along the guide rail 6 inside the mounting box 1 so that the target mold ring 7 and the diamond-coated wire drawing mold with different built-in apertures are aligned with the center of the fixed ring 25. The mold ring 7 is elastically supported by spring 23 and the guide rod 24 restricts its lateral offset to ensure accurate movement trajectory. The slider 11 is gripped through the operation port 2 to push the adjusting plate 10 to the target position. At this time, the axis of the mold ring 7 and the fixed ring 25 coincides, and the initial aperture selection is completed.

[0043] Pulling the pull rope 13 drives the rotating shaft 20 to rotate. The worm gear 17 drives the worm wheel 15 to rotate in conjunction with the rotating ring 8. The pressing block 21 rotates with the rotating ring 8 to the position aligned with the mounting post 30, pushing the selected mold ring 7 towards the fixing ring 25. When the pull rope 13 is released, the coil spring 18 tightens internally when the rotating shaft 20 rotates. The relaxed pull rope 13 releases the pulling force on the rotating shaft 20. Through the elastic force of the coil spring 18, the rotating shaft 20 is driven to rotate in the opposite direction, pushing the worm wheel 15 to rotate in the opposite direction. The coil spring 18 drives the rotating shaft 20 to rotate in the opposite direction. The worm gear 17 drives the worm wheel 15 to reset. The pressing block 21 presses the mounting post 30 to move inward, pushing the positioning block 29 into the positioning groove 14 on the outer wall of the mold ring 7, completing the rigid locking. The transmission between the worm wheel 15 and the worm gear 17 causes the pressing block 21 to press the mounting post 30. The spring 37 rebounds and pushes the positioning block 29 into the positioning groove 14, realizing the rapid fixing of the mold ring 7.

[0044] The mold ring 7 is reset to its initial position. Spring 1 23 provides a rebound force through guide rod 24 to ensure that the adjusting plate 10 is stably returned to its original position. The mold ring 7 exits the processing position. The sliding installation of slider 11 and guide rail 6 facilitates the cleaning of blocked metal chips. Spring 2 34 pushes pull rod 3 to reset. The mold ring 7 can be repositioned under the action of spring 1 23. The worm gear 15 and worm 17 transmission structure prevents rotation through the self-locking characteristic of worm 17, ensuring that the extrusion block 21 continuously applies pressure to the positioning block 29. The disc spring 18 provides the reset power for the rotating shaft 20, forming a fast operation logic of "push and pull to lock".

[0045] The ball bearing 31 at the end of the mounting column 30 rolls into contact with the extrusion block 21, reducing the coefficient of friction and ensuring smooth rotation of the rotating ring 8. The guide plate 35 and the sliding sleeve 36 support the bidirectional guide rail 6 of the pull rod 3, preventing skewing and jamming. The multi-mold ring 7 is pre-installed on the adjustment plate 10 and is aligned with the wire feeding hole 5 through the stroke groove 22, enabling hole diameter switching without external loading and unloading, shortening adjustment time, reducing downtime losses, and improving production line flexibility. Traditional mold changing is inefficient, relying on manual disassembly, handling, and calibration, which is time-consuming and prone to human error. Fixed molds are difficult to adapt to the flexible manufacturing needs of multi-specification orders, and frequent mold changes increase costs. This device is suitable for scenarios such as customized electronic wires and special alloy microwires that require frequent specification changes. Through mechanical linkage and flexible modular design, the use of diamond-coated wire drawing dies is optimized, simplifying the traditional "stop-disassembly-change-calibration" process into a "sliding-push-pull" operation, giving the production line the agility to quickly respond to market demands.

[0046] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
