Description

Technical Field

[0001] This invention relates to the field of diamond wire drawing technology, specifically to an ultra-fine diamond wire drawing device. Background Technology

[0002] Diamond wire drawing is a core process that involves cold-drawing and stretching high-strength wire rods (high-carbon steel or tungsten wire) into micron-level fine wires. After drawing, the wire rod must have ultra-high strength (to prevent wire breakage) and sufficient toughness. Finally, it is electroplated with diamond to make diamond wire, which is mainly used for cutting hard and brittle materials such as photovoltaic silicon wafers.

[0003] In actual operation, existing wire drawing equipment typically involves winding the busbar through two conical guide cylinders. As the busbar passes through the wire drawing die between the two guide cylinders, it relies on the rotational traction force of the guide cylinders to achieve continuous transmission, thereby completing the drawing and diameter reduction operation of the diamond wire busbar.

[0004] However, as the diameter of the busbar gradually decreases, the material undergoes severe plastic deformation, inevitably resulting in a large amount of heat accumulation. This leads to a significant increase in the temperature of the busbar itself. If the heat cannot be dissipated in time, the busbar is prone to breakage due to thermal softening or local overload under the subsequent continuous tensile force. Therefore, it is necessary to continuously spray lubricant onto the surface of the busbar during the production process. This helps to reduce the coefficient of friction, assists in wire drawing, and also provides forced cooling of the busbar through convection heat transfer. However, the currently commonly used spraying method has obvious shortcomings: the lubricant is often sprayed in a columnar or narrow fan shape, making it difficult to form a uniform coverage around the busbar. This can easily lead to local liquid accumulation or dry areas, resulting in uneven lubrication layer thickness. This uneven coating not only weakens the lubrication effect and increases the fluctuation of wire drawing resistance, but also causes inconsistent cooling along the length of the busbar. As a result, the problem of excessive local temperature rise is not fundamentally alleviated, ultimately affecting the accuracy of the finished wire diameter and surface quality.

[0005] Furthermore, during long-term operation, the working zone inside the wire drawing die is continuously subjected to high-pressure sliding friction. The diamond or cemented carbide die core will gradually develop microscopic wear and even obvious scratches. Once defects are formed on the inner wall of the channel, the surface of the busbar passing through the die will inevitably be left with axial grooves or scratches, directly damaging the surface smoothness and roundness of the busbar. This reduces the mechanical properties and fatigue life of the diamond busbar as a substrate for cutting or electroplating wires, severely restricting its reliable use in high-precision fields such as photovoltaics and semiconductors.

[0006] Based on this, the present invention provides an ultra-fine diamond wire drawing device to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides an ultra-fine diamond wire drawing device. The present invention has a novel structure and ingenious design, and effectively solves the technical problems of uneven cooling and lubrication and die wear leading to thermal wire breakage and surface scratches.

A positioning cylinder is fixedly connected to each of the two fixed seats. A guide cylinder is rotatably connected to each of the two positioning cylinders.

[0009] Preferably, each of the two positioning cylinders is rotatably connected to a rotating shaft, and one end of each rotating shaft is fixedly connected to the guide cylinder via a fixing frame.

[0010] Preferably, the top of the support block is provided with multiple through slots, and the bottom of each of the two placement slots is rotatably connected to multiple right rollers and left rollers.

[0011] Preferably, multiple adjustment slots are provided on both sides of the two placement slots, and sliders are slidably connected in each adjustment slot.

[0012] Preferably, a water storage hopper is fixedly connected to the frame, a processing cylinder is fixedly connected to the bottom of the water storage hopper, multiple filter ports are opened at the bottom of the processing cylinder, a discharge port is fixedly connected to one side of the processing cylinder, and a drainage hopper is fixedly connected to the bottom of the processing cylinder.

[0013] Preferably, a spiral shaft is rotatably connected to one side of the processing cylinder, and spiral blades are fixedly connected to the spiral shaft.

[0014] Preferably, a bracket is fixedly connected to the frame, a wire feeding frame is fixedly connected to one side of the bracket, a limit rod is slidably connected to the wire feeding frame, a placement plate is rotatably connected to the limit rod, and a buffer spring is fixedly connected to the bottom of the placement plate.

[0015] Preferably, the top of the frame is fixedly connected to a support plate and a support frame, a support shaft is rotatably connected to the support plate, and a take-up roller is sleeved on the support shaft.

[0016] Preferably, a working groove is provided on one side of the support frame, a fixed shaft is rotatably connected in the working groove, a rotating frame is rotatably connected on the fixed shaft, a torsion spring is sleeved on the fixed shaft, a sliding frame is fixedly connected to the rotating frame, a sliding plate is slidably connected in the sliding frame, and a guide ring is fixedly connected to the sliding plate.

[0017] Preferably, a left guide wheel is rotatably connected to the sliding frame, a right guide wheel is fixedly connected to the support shaft, the left and right guide wheels are driven by a drive belt to a main guide wheel, and a worm gear is fixedly connected to one end of the fixed shaft, the worm gear meshing with a worm.

[0018] The present invention has the following technical effects.

[0019] 1. This invention discharges lubricating fluid into the guide groove of the winding busbar through a positioning cylinder, water supply pipe, water storage tank, and water outlet. This enables the lubricating fluid to form a uniform, continuous, and complete liquid film covering the busbar during the wire drawing process, effectively eliminating dead corners in the coating and ensuring a consistent lubrication layer thickness, thereby significantly improving lubrication efficiency. At the same time, the flow and circulation of the lubricating fluid can promptly remove the frictional heat generated by the wire drawing deformation, avoiding the risk of wire breakage caused by heat accumulation. Uniform and sufficient lubrication can also reduce the wear rate of the inner wall of the mold and reduce scratch defects.

[0020] 2. This invention uses a left roller, a right roller, a limiting wheel, and a toothed belt to make the wire drawing die rotate continuously during the wire drawing process. This allows the wire to dynamically change its contact position circumferentially within the die hole, avoiding excessive local wear of the hole wall caused by long-term fixed-point friction. This effectively delays the formation of scratches and significantly extends the service life of the die.

[0021] 3. This invention uses a processing cylinder, spiral blades, a filter port, and a drain bucket to collect and process used lubricating fluid, filtering out impurities carried by the lubricating fluid, so that the processed lubricating fluid can be reused.

[0022] 4. This invention, through a fixed shaft, rotating frame, torsion spring, and transmission belt, can identify abnormal tension expansion at the moment of busbar breakage and promptly stop the winding action, effectively preventing the broken busbar from continuing to be wound into the winding roller and causing faults such as tangled wire, entanglement, or equipment jamming, thus significantly reducing production downtime and manual cleaning costs.

[0036] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 11 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0037] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0038] This invention relates to an ultra-fine diamond wire drawing device, comprising a frame 1 and a mounting base 2. Two fixed seats 3 and a support block 15 are fixedly connected to the mounting base 2. The height of the top of the support block 15 gradually decreases from the side away from the mounting base 2 toward the side of the mounting base 2, and the angle of decrease is parallel to the taper of the guide cylinder 5. A positioning cylinder 4 is fixedly connected to each of the two fixed seats 3, and a guide cylinder 5 is rotatably connected to each of the two positioning cylinders 4. Both guide cylinders 5 are conical and have the same shape and size.

[0039] Multiple guide grooves 6 are provided on the guide cylinder 5. The guide grooves 6 are semi-circular and are evenly distributed on the guide cylinder 5. The diameter of the guide grooves 6 varies along the conical surface of the guide cylinder 5. Multiple water outlet holes 7 are provided in each of the multiple guide grooves 6. The multiple water outlet holes 7 in one guide groove 6 are evenly distributed in the guide groove 6 and are connected to the inner diameter of the guide cylinder 5.

[0040] Multiple annular water storage tanks 12 are provided on the two positioning cylinders 4. The distance between two adjacent water storage tanks 12 is the same as the distance between two adjacent guide grooves 6. The multiple water storage tanks 12 correspond one-to-one with the multiple guide grooves 6 on the guide cylinder 5.

[0041] Multiple water supply pipes 13 are fixedly connected to one side of each of the two positioning cylinders 4. The multiple water supply pipes 13 are evenly distributed in a circle on the positioning cylinder 4. The number of water supply pipes 13 is equal to the number of water storage tanks 12. One end of each of the multiple water supply pipes 13 is connected to the multiple water storage tanks 12.

[0042] The top of the support block 15 has two placement slots 16, and multiple wire drawing dies are placed in each of the two placement slots 16.

[0043] Both positioning cylinders 4 have a central hole, and a rotating shaft 9 is rotatably connected to each of the two central holes. One end of each rotating shaft 9 is fixedly connected to a fixing bracket 8, and one side of each fixing bracket 8 is fixedly connected to one side of the guide cylinder 5.

[0044] In this embodiment, during the wire drawing process, one end of the diamond wire is first ground to form a sharp head. Then, the sharp end passes through the first guide groove 6 near the mounting base 2 on the left guide cylinder 5, then through the wire drawing die on the support block 15, and then through the first guide groove 6 near the mounting base 2 on the right guide cylinder 5. Next, the diamond wire is wound around the right guide cylinder 5, and then pulled in the opposite direction to pass through the wire drawing die on the support block 15 again. Then, the diamond wire is wound around the second guide groove 6 on the left guide cylinder 5 and passed through the left guide cylinder 5. Then, the diamond wire is pulled in the opposite direction again to pass through the wire drawing die on the support block 15 again. This process is repeated to allow the diamond wire to pass through multiple wire drawing dies in sequence, thereby gradually achieving the wire drawing requirements of the diamond wire.

[0045] During the wire drawing process, lubricating fluid is discharged into multiple water supply pipes 13. The lubricating fluid is then diverted through the multiple water supply pipes 13 and enters multiple water storage tanks 12 set on the positioning cylinder 4. After passing through the multiple water storage tanks 12 on the positioning cylinder 4, it enters the water outlet holes 7 set on the guide cylinder 5. After passing through these water outlet holes 7, it enters the guide grooves 6 set on the guide cylinder 5. Due to the influence of its own surface tension, the lubricating fluid flows in the guide grooves 6 and fills the guide grooves 6, thereby lubricating the diamond busbar passing through the guide grooves 6 and ensuring that the lubricating fluid fully coats the surface of the diamond busbar. During the continuous discharge of lubricating fluid into the guide grooves 6 through the water outlet holes 7 on the guide cylinder 5, excess lubricating fluid will drip downwards from the bottom of the guide cylinder 5. A splash guard is detachably installed on the guide cylinder 5, which is hidden in the figure and is not shown.

[0046] As one embodiment, the top of the support block 15 is provided with multiple through slots 17, the top of the through slots 17 passes through the top of the support block 15, the distance between two adjacent through slots 17 is the same as the distance between two adjacent guide slots 6, the multiple through slots 17 transversely pass through two placement slots 16, the bottom of each of the two placement slots 16 is rotatably connected with multiple right rollers 18 and left rollers 19, adjacent left rollers 19 and right rollers 18 form a group, which cooperate with each other to support the placed wire drawing mold. Since the wire drawing molds on the two placement slots 16 are placed in a staggered manner, the right rollers 18 and left rollers 19 on the two placement slots 16 are also staggered.

[0047] One implementable driving embodiment is provided:

[0048] The wire drawing die is placed on top of the adjacent right roller 18 and left roller 19. The end shafts of multiple left rollers 19 pass through the support block 15 and are fixedly connected to the auxiliary toothed pulleys 21. Toothed belts 20 are fitted on the auxiliary toothed pulleys 21 on both sides of the support block 15. Protective shells 22 are provided on both sides of the support block 15. The protective shells 22 shield and protect the auxiliary toothed pulleys 21 and the fitted toothed belts 20. A drive shaft 23 is rotatably connected to one side of the inner wall of the mounting base 2. Two main toothed pulleys 24 are provided on the drive shaft 23. The two toothed belts 20 pass through the mounting base 2 and are fitted on the two main toothed pulleys 24.

[0049] A servo motor 10 is fixedly connected to the bottom of the inner wall of the mounting base 2. The output shaft of the servo motor 10 is fitted with two conveyor belts 11 and a twisting conveyor belt via pulleys. The other end of the two conveyor belts 11 is fitted onto the pulleys at one end of the two rotating shafts 9, and the other end of the twisting conveyor belt is fitted onto the pulley on the drive shaft 23.

[0050] As an example, multiple adjustment slots 25 are provided on both sides of the two placement slots 16. The adjustment slots 25 are rectangular. Slider 26 are slidably connected in the two opposite adjustment slots 25 on both sides of the placement slot 16. A return spring 27 is fixedly connected to one side of the slider 26, and the other end of the return spring 27 is fixedly connected to one side of the adjustment slot 25. A support rod 28 is fixedly connected between the two sliders 26. A limit wheel 29 is rotatably connected to the support rod 28. The limit wheel 29 cooperates with the left roller 19 and the right roller 18 below to form a circular shape.

[0051] In this embodiment, before the wire drawing operation begins, the sharp end of the diamond wire, formed by grinding, is first inserted into the wire drawing die through a hole at one end of the die, and the sharp end is then pulled out from the other side of the die. The diamond wire is then pulled through the die to complete the initial wire drawing operation. After the diamond wire passes through the die, the operator places the die, which has passed the wire, on top of the left roller 19 and the right roller 18.

[0052] Before placing the die, the limiting wheel 29 and its connected support rod 28 must be pushed to move them away from the center of the left roller 19 and the right roller 18. During this movement, the support rod 28 drives the two sliders 26 to slide in the two adjustment grooves 25 respectively, while simultaneously pressing the return spring 27 between the sliders 26 and the adjustment grooves 25. This causes the return spring 27 to exert a reverse force on the sliders 26. After the drawing die is placed on top of the left roller 19 and the right roller 18, the return spring 27 pushes the two sliders 26 to slide back along the adjustment grooves 25. The two sliders 26 drive the two support rods 28 and the limiting wheel 29 on the support rods 28 to move back in the opposite direction until the limiting wheel 29 contacts the top side of the drawing die. Through the cooperation of the left roller 19, the right roller 18 and the limiting wheel 29, the drawing die placed on them is limited.

[0053] During the wire drawing operation, the servo motor 10 drives the conveyor belt 11 for conveying. The conveyor belt 11 drives two rotating shafts 9 to rotate inside two positioning cylinders 4. The two rotating shafts 9 drive two guide cylinders 5 to rotate synchronously through the fixed frame 8 connected to one end of them. The rotation of the guide cylinders 5 drives the diamond wire to rotate, thereby realizing the wire drawing operation. At the same time as the servo motor 10 is working, the drive shaft 23 is driven to rotate by twisting the conveyor belt. The drive shaft 23 drives two main toothed pulleys 24 to rotate synchronously. The two main toothed pulleys 24 drive multiple auxiliary toothed pulleys 21 to rotate synchronously through the transmission of two toothed belts 20. The multiple auxiliary toothed pulleys 21 then drive multiple left rollers 19 to rotate synchronously. When the left rollers 19 rotate, they cooperate with the wire drawing die that is in contact with the top, so that the wire drawing die can rotate in coordination with the wire during the wire drawing process.

[0054] It should be noted that the servo motor 10 is connected to a power supply and a controller, which are existing technologies and therefore not described in detail.

[0055] As an example, a water storage hopper 30 is fixedly connected to the frame 1. The two sides of the water storage hopper 30 are inclined. A processing cylinder 31 is fixedly connected to the bottom of the water storage hopper 30. The processing cylinder 31 is semi-circular. Multiple filter ports 32 are opened at the bottom of the processing cylinder 31. A discharge port 35 is fixedly connected to one side of the processing cylinder 31. One end of the discharge port 35 has the same diameter as the processing cylinder 31, and the diameter of the other end is smaller than the diameter of the processing cylinder 31. A drainage hopper 36 is fixedly connected to the bottom of the water storage hopper 30. The drainage hopper 36 is shaped like a "U". The bottom of the inner wall of the drainage hopper 36 is sloping. The part of the processing cylinder 31 located below the water storage hopper 30 is located inside the drainage hopper 36.

[0056] As an example, a spiral shaft 33 is rotatably connected to one side of the processing cylinder 31, and a motor is connected to one side of the processing cylinder 31. One end of the spiral shaft 33 passes through the processing cylinder 31 and is connected to the output shaft of the motor. A spiral blade 34 is fixedly connected to the spiral shaft 33, and the edge of the spiral blade 34 cooperates with the inner wall of the processing cylinder 31.

[0057] More detailed implementation methods are provided:

[0058] A water tank 37 is fixedly connected to the bottom of the inner wall of the frame 1. The water inlet at the top of the water tank 37 is located below the drain hopper 36, so that the water discharged from the drain hopper 36 falls smoothly into the water tank 37. A connecting pipe 38 is provided at the outlet of the water tank 37. A submersible pump is connected inside the water tank 37. One end of the connecting pipe 38 inside the water tank 37 is connected to the output end of the submersible pump. The other end of the connecting pipe 38 is fixedly connected to two annular conveying pipes 14. The two conveying pipes 14 are respectively fixedly connected to one side of the two positioning cylinders 4. The two conveying pipes 14 are respectively connected to the water supply pipes 13 on the two positioning cylinders 4.

[0059] In this embodiment, by driving a submersible pump, the submersible pump draws lubricating fluid from inside the water tank 37. The drawn lubricating fluid is transported through a connecting pipe 38 to an annular delivery pipe 14, and then diverted through the annular delivery pipe 14 into multiple water delivery pipes 13. Thus, the lubricating fluid is discharged into the guide groove 6 provided on the guide cylinder 5 through the multiple water delivery pipes 13, and lubricated on the diamond busbar wound through the guide groove 6. During the continuous injection of lubricating fluid into the guide groove 6, excess lubricating fluid drips down from the bottom of the guide cylinder 5 and falls into the water storage hopper 30 provided below the guide cylinder 5. Then, it flows into the processing cylinder 31 through the water storage hopper 30. The lubricating fluid entering the processing cylinder 31 is filtered through the filter port 32 provided on the processing cylinder 31. The filtered lubricating fluid falls into the drain hopper 36 provided below the filter port 32, and finally, it is discharged back into the water tank 37 through the drain hopper 36, thereby realizing the recycling of lubricating fluid and facilitating continuous lubrication operations.

[0060] At the same time, the motor drives the spiral shaft 33 inside the processing cylinder 31 to rotate. During the rotation, the spiral shaft 33 drives the spiral blades 34 on it to rotate synchronously. The spiral blades 34 push the debris filtered out by the filter port 32 towards the discharge port 35 at the bottom of the processing cylinder 31. The debris gradually moves towards the discharge port 35 at the bottom of the processing cylinder 31 until it is discharged at the discharge port 35 for centralized collection and processing.

[0061] It should be noted that both the motor and the submersible pump are connected to a power supply and a controller. The motor, submersible pump, power supply, and controller are existing technologies, so they are not described in detail.

[0062] As an example, a bracket 39 is fixedly connected to the top of the frame 1, and a wire feeding frame 40 is fixedly connected to one side of the bracket 39. The wire feeding frame 40 is circular, and a circular groove is opened at the bottom of the wire feeding frame 40. The center line of the groove coincides with the center line of the wire feeding frame 40. A limit rod 41 is slidably connected in the groove. A placement plate 42 is rotatably connected to the limit rod 41. The placement plate 42 is conical and is located inside the wire feeding frame 40. A buffer spring 43 is fixedly connected to the bottom of the placement plate 42. The buffer spring 43 is sleeved on the limit rod 41, and the other end of the buffer spring 43 is fixedly connected to the top of the wire feeding frame 40.

[0063] In this embodiment, the diamond wire roller that needs to be drawn is placed on the limiting rod 41. The placing plate 42 on the limiting rod 41 supports the diamond wire roller. When the diamond wire is pulled, the placing plate 42 supports the diamond wire roller and rotates to facilitate the smooth release of the diamond wire. When the diamond wire is caught on the diamond wire roller and encounters pulling resistance, the resistance will cause the limiting rod 41 to slide down on the wire release frame 40. At the same time, the placing plate 42 descends synchronously with the limiting rod 41 and squeezes the buffer spring 43 located below the placing plate 42. The buffer spring 43 generates a reverse thrust on the placing plate 42, thereby buffering the resistance encountered when pulling the diamond wire. When the resistance decreases, the buffer spring 43 pushes the placing plate 42 and the limiting rod 41 to rise and reset to the initial position.

[0064] As an example, a support plate 44 and a support frame 45 are fixedly connected to the top of the frame 1. A support shaft 46 is rotatably connected to the support plate 44. A take-up roller 47 is sleeved on the support shaft 46. The support shaft 46 limits the take-up roller 47 by fixing bolts 48.

[0065] A working groove 49 is provided on one side of the support frame 45. The working groove 49 is rectangular in shape and has a sloping bottom. A fixed shaft 50 is rotatably connected inside the working groove 49. A rotating frame 51 is rotatably connected to the fixed shaft 50. Torsion springs 52 are fixedly connected to both sides of the rotating frame 51. Two baffles are fixedly connected to the fixed shaft 50. The two baffles are located on both sides of the rotating frame 51. The two ends of the two torsion springs 52 are fixedly connected to the opposite sides of the two baffles. A sliding frame 56 is fixedly connected to the other side of the rotating frame 51. The sliding frame 56 is in the shape of an "U". A sliding plate 57 is slidably connected inside the sliding frame 56. A guide ring 58 is fixedly connected to the other side of the sliding plate 57.

[0066] More specifically: an electric push rod 59 is fixedly connected to one side of the sliding frame 56, and the output end of the electric push rod 59 is fixedly connected to one side of the sliding plate 57.

[0067] As an example, a drive motor 61 is fixedly connected to the top of the frame 1, and a main guide wheel 62 is fixedly connected to the output shaft of the drive motor 61. A left guide wheel 60 is rotatably connected to the bottom of the sliding frame 56, and a right guide wheel 63 is fixedly connected to the support shaft 46. A transmission belt 64 is fitted on the main guide wheel 62, the left guide wheel 60, and the right guide wheel 63. One end of the fixed shaft 50 passes through the support frame 45 and is fixedly connected to a worm gear 53. A bearing seat 54 is fixedly connected to one side of the support frame 45, and a worm 55 is rotatably connected to the bearing seat 54. The worm 55 meshes with the worm gear 53.

[0068] In this embodiment, the drive motor 61 operates, driving the main guide wheel 62 to rotate, thereby driving the transmission belt 64 sleeved on the main guide wheel 62 to transmit power. Through the transmission action of the transmission belt 64, the left auxiliary guide wheel 60 and the right auxiliary guide wheel 63 on both sides are driven to rotate synchronously. The right auxiliary guide wheel 63 drives the support shaft 46 to rotate on the support plate 44 through its rotation. The support shaft 46 further drives the take-up roller 47 on it to rotate synchronously, thereby tightening and winding the diamond wire after the wire drawing operation.

[0069] During the winding process, the electric push rod 59 operates, which drives the sliding plate 57 to slide back and forth within the sliding frame 56. The sliding plate 57 drives the guide ring 58 set on it to move back and forth synchronously, thereby evenly winding the diamond wire onto the winding roller 47.

[0070] In addition to the electric push rod 59 driving the sliding plate 57 to reciprocate to achieve uniform winding, an alternative embodiment can achieve uniform winding through the reciprocating motion of a lead screw transmission mechanism.

[0071] During the wire drawing process, when the diamond busbar is about to break, the tension on the busbar itself will suddenly increase. In this case, the take-up roller 47 continuously tightens the diamond busbar. This tension will cause the rotating frame 51 to rotate around the fixed shaft 50. During the rotation, the rotating frame 51 will cause the sliding frame 56 and the left auxiliary wheel 60 located at the bottom of the sliding frame 56 to descend synchronously, causing the left auxiliary wheel 60 to move closer to the main guide wheel 62. As a result, the main guide wheel 62, the left auxiliary wheel 60 and the right auxiliary wheel 63 will be unable to tighten the transmission belt 64. The transmission belt 64 will therefore lose its transmission capacity and will not be able to drive the right auxiliary wheel 63 to rotate. This will stop the take-up roller 47 from winding the diamond busbar, so that the workers can deal with the diamond busbar that is about to break in time.

[0072] When the rotating frame 51 descends and rotates, it simultaneously drives the torsion spring 52 connected to it to twist, causing the torsion spring 52 to exert a reverse force on the rotating frame 51. After the staff has adjusted and the tension has returned to normal, the torsion spring 52 drives the rotating frame 51 to rotate in the opposite direction to reset, so that the left guide wheel 60 returns to its initial position and the transmission belt 64 is tightened again, so that the winding roller 47 can rewind the diamond busbar.

[0073] To meet different winding requirements, the operator can turn the worm 55 to rotate on the bearing seat 54. The rotation of the worm 55 drives the worm wheel 53 meshing with it to rotate synchronously. The worm wheel 53 further drives the fixed shaft 50 and the torsion spring 52 fixed on the fixed shaft 50 to rotate synchronously, thereby increasing or decreasing the torsional force generated by the torsion spring 52 on the rotating frame 51 to adjust the winding tension.

[0074] It should be noted that both the drive motor 61 and the electric push rod 59 are connected to a power supply and a controller. The power supply and controller are existing technologies, so they are not described in detail.

[0075] Working principle of this invention:

[0076] In use, the diamond wire roller that needs to be drawn is placed on the limiting rod 41. One end of the diamond wire is ground to form a sharp head. Then, the sharp end first passes through the guide groove 6 on the left guide cylinder 5 and is inserted into the drawing die installed on the support block 15. Then, it is wound through the guide groove 6 on the right guide cylinder 5. Then, the diamond wire is pulled in the opposite direction so that it passes through the drawing die on the support block 15 again and is wound through the guide groove 6 on the left guide cylinder 5. The above operation is repeated according to the process requirements to complete the drawing operation of the diamond wire. After the drawing and winding are completed, the diamond wire passes through the guide wheel on the right, passes through the guide ring 58, and is finally wound on the take-up roller 47. The drive motor 61 drives the take-up roller 47 to rotate and perform the winding operation of the diamond wire after drawing.

[0077] During the winding process, when the diamond wire is about to break, the tension on the diamond wire itself will suddenly increase. This tension change will cause the rotating frame 51 and the guide ring 58 set on the rotating frame 51 to descend synchronously, thereby stopping the drive of the winding roller 47 and stopping the winding roller 47 from winding the drawn diamond wire. This allows the staff to deal with the position where the wire is about to break in time.

[0078] During the wire drawing process of the diamond busbar through the guide cylinder 5, lubricating fluid is extracted from the water tank 37 and diverted through the delivery pipe 14 into multiple water supply pipes 13. The lubricating fluid then enters multiple water storage tanks 12 on the positioning cylinder 4, and then flows through the multiple water storage tanks 12 on the positioning cylinder 4 into the water outlet 7 on the guide cylinder 5. Finally, the lubricating fluid is discharged into the guide groove 6 on the guide cylinder 5 through the water outlet 7. The lubricating fluid gradually fills the guide groove 6, fully wetting the diamond busbar wound through the guide groove 6, which facilitates subsequent wire drawing and cooling operations.

[0079] The lubricating fluid flows in the guide groove 6 on the guide cylinder 5. After the guide groove 6 is filled, the excess lubricating fluid drips down from the bottom of the guide cylinder 5 and falls into the water storage hopper 30 located below the guide cylinder 5. It then enters the processing cylinder 31 and is filtered through the filter port 32 located at the bottom of the processing cylinder 31. At the same time, the rotation of the spiral shaft 33 drives the spiral blades 34 located on the spiral shaft 33 to push the impurities filtered out by the filter port 32. The filtered lubricating fluid flows out from one side of the processing cylinder 31 through the drain hopper 36 and falls into the water tank 37 for easy recycling.

[0080] The wire drawing die for drawing the diamond wire is placed at the top of the left roller 19 and the right roller 18. The wire drawing die is limited by the limiting wheel 29 on one side. The servo motor 10 drives the toothed belt 20 to drive the multiple left rollers 19 to rotate synchronously. The multiple left rollers 19 drive the wire drawing die placed on them to rotate synchronously. Thus, during the wire drawing process of the diamond wire, the wire drawing die can rotate synchronously with the wire, effectively reducing the scratches on the surface of the diamond wire and improving the wire drawing quality.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
