Description

Technical Field

[0001] This invention belongs to the field of drawing technology, specifically a stainless steel alloy grounding wire drawing device. Background Technology

[0002] In the field of precision wire processing of non-ferrous metals and alloys, drawing is a core technology for achieving dimensional accuracy control and mechanical property optimization of metal wires. Stainless steel and alloy grounding wire drawing equipment is suitable for precision drawing of high-quality aluminum alloy plates, high-quality magnesium, copper, titanium, and other non-ferrous metals and their alloys, including wires, bars, and rods, as well as cold drawing of titanium alloy wires. It can also be extended to the processing of ferrous metal wires such as carbon steel and stainless steel, and is compatible with various drawing modes including single-pass, multi-pass continuous, wet, and dry drawing.

[0003] A patent with publication number CN118080591B discloses a metal wire drawing device, including a U-shaped frame and a base fixedly connected to the bottom of the U-shaped frame. A winding mechanism is installed on the top of the U-shaped frame, and a metal wire is wound around the winding mechanism. Two optical shafts are installed in the middle cavity of the mounting plate. The two optical shafts slide together with two powder coating components, and the two powder coating components elastically clamp the free end of the metal wire. A vibration powder feeding component is installed on the top of each powder coating component. A powder chamber is fixedly installed on the top of the U-shaped frame. A flexible tube is connected to the top of each vibration powder feeding component, and each flexible tube is connected to the bottom of the powder chamber. A mounting frame is fixedly installed in the middle of the U-shaped frame, and a drawing die sleeve is spirally installed on the mounting frame.

[0004] Existing metal wire drawing equipment typically coats the raw metal wire with solid lubricating powder before it enters the drawing die. This powder forms an insulating lubricating layer, reducing friction between the wire and the die, alleviating tensile stress concentration, and lowering the wire breakage rate. However, untreated raw metal wires have smooth, clean surfaces without microscopic grooves. The lubricating powder adheres to the wire surface only through weak physical adsorption, resulting in poor adhesion. During the wire's transport by guide rollers, roller compression, airflow in the workshop, and the wire's own vibrations all cause significant loss of the surface lubricating powder, with most powder falling off and being wasted before reaching the drawing deformation zone. The remaining lubricating powder is unevenly distributed, failing to form a complete lubricating film on the contact surface, leading to localized dry friction. This not only scratches the wire surface and creates burr defects but also exacerbates die wear and stress concentration, significantly increasing the probability of wire breakage. The scattered lubricating dust accumulates throughout the equipment, increasing cleaning workload and lubricating powder consumption, negatively impacting production costs and stability.

[0005] Therefore, the present invention provides a stainless steel olefin alloy grounding wire pulling device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The stainless steel alloy grounding wire drawing device of the present invention includes a machine body, two support frames are fixedly connected to the upper surface of the machine body, and a rotating roller is rotatably arranged at the top of the two support frames. The original wire is wound on the circumferential surface of the rotating roller. A positioning box, a fixed frame and a fixed roller are also fixedly connected between the two support frames. A powder coating frame is arranged in the middle of the fixed frame. A pretreatment component is arranged on one side of the positioning box. The pretreatment component includes a fixed box fixed to one side of the positioning box. A rotating grinding block is arranged inside the fixed box. The grinding block can pre-grind the circumferential surface of the original wire, so that the surface of the original wire presents a threaded groove. An auxiliary component is also arranged on the lower surface of the positioning box. The auxiliary component is used to assist the adhesion of lubricating powder.

[0008] Preferably, the pretreatment component further includes a fixed motor fixed to the surface of the fixed box, the output end of the fixed motor is fixedly connected to a first gear, the first gear meshes with a second gear, and a grinding block is inserted into the middle of the second gear.

[0009] Preferably, a positioning rod is fixedly connected to the upper surface of the grinding block, a rotating groove is provided on the upper surface of the fixed box, a sliding rod is slidably connected in the rotating groove, a positioning block is fixedly connected to the top of the sliding rod, connecting rods are rotatably connected to both sides of the positioning block, a common connecting magnetic block is fixedly connected to one end of the two connecting rods, and two insert plates are fixedly connected to the lower surface of the connecting magnetic block, the two insert plates can insert and limit the positioning rod.

[0010] Preferably, the positioning box stores lubricating powder, and the lubricating powder in the positioning box is connected to the powder coating frame on the fixed frame. The powder coating frame is coated by the raw filament pulled by the powder coating belt set inside.

[0011] Preferably, the auxiliary component includes an auxiliary box fixed to the lower surface of the fixed box, a positioning tube fixed to one side of the auxiliary box, the positioning tube communicating with the auxiliary box, and a plurality of spray holes opened on the inner wall of the positioning tube, which can spray a base coat liquid onto the thread grooves on the surface of the raw yarn.

[0012] Preferably, the output end of the fixed motor is connected to a transmission belt, an auxiliary plate is fixedly connected to one side of the auxiliary box, a connecting shaft is rotatably connected to the auxiliary plate, the connecting shaft is connected to the transmission belt, a cam is fixedly connected to the bottom end of the connecting shaft, a conical plate is elastically connected inside the auxiliary box, and the cam squeezes the conical plate to connect the auxiliary box and the positioning tube for spraying the base coat liquid.

[0013] Preferably, the auxiliary box has a positioning groove inside, and a compression spring is fixed to the inner wall of the positioning groove. One end of the compression spring is fixed to the conical plate. The surface of the conical plate has a positioning hole. The auxiliary box also has a connecting groove. After the conical plate is squeezed into the positioning groove by the cam, the positioning hole is aligned with the connecting groove, and the storage cavity inside the auxiliary box is connected.

[0014] Preferably, during the drawing of the raw filament, one end of the raw filament first passes through the fixed box, the powder coating frame, and the fixed roller before being drawn. During the drawing process, the fixed motor on the upper surface of the fixed box is started. The start of the fixed motor drives the first gear at its output end to rotate. The rotation of the first gear drives the second gear with it to rotate. The rotation of the second gear drives the grinding block inserted inside to rotate. The rotating grinding block grinds a threaded groove on the circumference of the raw filament. After the pretreatment is completed, the raw filament continues to be drawn so that it passes through the powder coating frame for powder coating. After the powder coating is completed, the drawing process is carried out.

[0015] Preferably, after the grinding block has been ground, during the replacement process, first rotate the connecting magnetic block that is locked at the top of the positioning rod to release the locking of the positioning rod by the connecting magnetic block and the insert plate. As the grinding block rotates, it will drive the positioning rod to rotate synchronously. The positioning rod is magnetically attracted by the connecting magnetic block and locked by the insert plate, thus driving the connecting magnetic block to slide synchronously along the rotating groove. A sliding rod is slidably connected in the rotating groove. Two connecting rods are rotatably connected to the positioning block at the top of the sliding rod. The connecting magnetic block is fixed to the ends of the two connecting rods. Therefore, when replacing the grinding block, first contact the limit of the connecting magnetic block, and then pull the positioning rod to remove the grinding block for replacement.

[0016] Preferably, while the grinding block is undergoing pretreatment, the fixed motor synchronously drives the transmission belt to perform transmission work. The synchronous transmission work of the transmission belt drives the cam at the bottom of the connecting shaft to rotate. The rotation of the cam compresses the cone plate into the positioning groove. After the cone plate is compressed into the positioning groove, the positioning hole on the surface of the cone plate will align with the slot hole at one end of the connecting groove and will connect to the storage cavity inside the auxiliary box. The solidifying liquid in the storage cavity flows into the positioning tube under pressure and is sprayed out through several spray holes on the inner wall of the positioning tube, spraying into the thread groove of the original wire to assist in the lubrication application work.

[0017] The beneficial effects of this invention are as follows: 1. The stainless steel alloy grounding wire drawing equipment of the present invention simultaneously grinds the threaded grooves on the surface of the raw wire before drawing. A fixed motor drives the first gear and the second gear to drive the grinding block to rotate, thus machining continuous spiral grooves on the outer circumference of the raw wire. This improves the adhesion and bonding strength of the lubricating powder, effectively reduces powder fall-off after powdering, and reduces wire breakage and wire scratches during drawing. At the same time, the grinding block adopts a double limiting structure of magnetic attraction and insertion plate. During disassembly, only the top connecting magnetic block needs to be rotated to release the locking of the positioning rod, without the need for complicated disassembly and assembly tools. When the grinding block rotates, the positioning rod and sliding component can slide synchronously along the rotating groove without interfering with the grinding operation. It has the advantages of online pre-processing and quick mold change, eliminating the need to add a separate grinding station, shortening the production line length, and making the grinding block replacement operation simple and time-saving, thereby improving equipment operation and maintenance efficiency and continuous production stability.

[0018] 2. The stainless steel alloy grounding wire drawing equipment of the present invention uses a cam that rotates with the transmission belt to periodically squeeze the conical plate, thereby achieving intermittent quantitative supply of pre-coated base liquid. The liquid is sprayed into the groove of the original wire thread through the spray hole. The pre-coated liquid fills the groove to form a bonding base. In combination with the spiral pattern, it greatly enhances the adhesion of the lubricating powder, reduces powder shedding, and automatically controls the liquid spraying to be uniform, effectively improving the subsequent drawing lubrication effect and reducing wire breakage and raw material loss.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 7 As shown in the embodiment of the present invention, a stainless steel alloy grounding wire drawing device has two support frames 11 fixedly attached to the upper surface of the machine body 1. A rotating roller 12 is rotatably mounted on the top of each support frame 11, and a raw wire is wound onto the circumferential surface of the rotating roller 12. A positioning box 13, a fixed frame 14, and a fixed roller 16 are also fixedly connected between the two support frames 11. A powder coating frame 15 is provided in the middle of the fixed frame 14. A pretreatment component is provided on one side of the positioning box 13. The pretreatment component includes a fixed box 2 fixedly attached to one side of the positioning box 13. A rotating grinding block 29 is provided inside the fixed box 2, which can pre-grind the circumferential surface of the raw wire, making the surface of the raw wire exhibit a threaded groove. An auxiliary component is also provided on the lower surface of the positioning box 13 to assist in the adhesion of lubricating powder. The pretreatment component also includes a fixed motor 2 fixedly attached to the surface of the fixed box 2. 1. A first gear 210 is fixedly connected to the output end of the fixed motor 21. The first gear 210 meshes with a second gear 211. A grinding block 29 is inserted into the middle of the second gear 211. A positioning rod 24 is fixedly connected to the upper surface of the grinding block 29. A rotating groove 22 is opened on the upper surface of the fixed box 2. A sliding rod 23 is slidably connected in the rotating groove 22. A positioning block 25 is fixedly connected to the top of the sliding rod 23. A connecting rod 26 is rotatably connected to both sides of the positioning block 25. A connecting magnetic block 27 is fixedly connected to one end of the two connecting rods 26. Two insert plates 28 are fixedly connected to the lower surface of the connecting magnetic block 27. The two insert plates 28 can insert and limit the positioning rod 24. The positioning box 13 stores lubricating powder. The lubricating powder in the positioning box 13 is connected to the powder coating frame 15 on the fixed frame 14. The powder coating frame 15 is coated by the original filament pulled by the powder coating belt set inside.

[0023] Specifically, existing metal wire drawing equipment typically coats the raw metal wire with solid lubricating powder before it enters the drawing die. This powder forms an insulating lubricating layer, reducing friction between the wire and the die, alleviating tensile stress concentration, and lowering the wire breakage rate. However, untreated raw metal wires have smooth, clean surfaces without microscopic grooves. The lubricating powder adheres to the wire surface only through weak physical adsorption, resulting in poor adhesion. During the wire's transport by guide rollers, roller compression, airflow in the workshop, and the wire's own vibrations all cause significant loss of the surface lubricating powder, with most of it falling off and being wasted before reaching the drawing deformation zone. The remaining lubricating powder is unevenly distributed, failing to form a complete lubricating film on the contact surface, leading to localized dry friction. This not only scratches the wire surface and creates burr defects but also exacerbates die wear and stress concentration, significantly increasing the probability of wire breakage. The scattered lubricating dust accumulates throughout the equipment, increasing cleaning workload and lubricating powder consumption, negatively impacting production costs and stability. Therefore, the present invention solves the above problems by setting up the above structure. First, when the raw filament is being drawn, one end of the raw filament passes through the fixed box 2, the powder coating frame 15 and the fixed roller 16 before being drawn. During the drawing process, the fixed motor 21 on the upper surface of the fixed box 2 is started. The start of the fixed motor 21 drives the first gear 210 at its output end to rotate. The rotation of the first gear 210 drives the second gear 211 to rotate. The rotation of the second gear 211 drives the grinding block 29 inserted inside to rotate. The rotating grinding block 29 grinds a threaded groove on the circumference of the raw filament. After the pretreatment is completed, the raw filament continues to be drawn so that it passes through the powder coating frame 15 for powder coating. After the powder coating is completed, the drawing process is carried out. After the grinding block 29 is polished, during the replacement process, first rotate the connecting magnetic block 27 that is locked at the top of the positioning rod 24 to release the locking of the positioning rod 24 by the connecting magnetic block 27 and the insert plate 28. During the rotation of the grinding block 29, it will drive the positioning rod 24 to rotate synchronously. The positioning rod 24 is magnetically attracted by the connecting magnetic block 27 and locked by the insert plate 28, thus driving the connecting magnetic block 27 to slide synchronously along the rotating groove 22. A sliding rod 23 is slidably connected in the rotating groove 22. Two connecting rods 26 are rotatably connected to the positioning block 25 at the top of the sliding rod 23. The connecting magnetic block 27 is fixed to the ends of the two connecting rods 26. Therefore, when replacing the grinding block 29, first contact the limit of the connecting magnetic block 27, and then pull the positioning rod 24 to remove the grinding block 29 for replacement. By simultaneously grinding the threaded grooves on the surface of the raw wire before drawing, the fixed motor 21 drives the first gear 210 and the second gear 211 to drive the grinding block 29 to rotate, thus machining continuous spiral grooves on the outer circumference of the raw wire. This improves the adhesion and bonding strength of the lubricating powder, effectively reducing powder shedding after coating and reducing problems such as wire breakage and wire scratches during drawing. At the same time, the grinding block 29 adopts a double limiting structure with magnetic attraction and insert plate 28. During disassembly, only the top connecting magnetic block 27 needs to be rotated to release the locking of the positioning rod 24, without the need for complicated disassembly tools. When the grinding block 29 rotates, the positioning rod 24 and the sliding component can slide synchronously along the rotating groove 22 without interfering with the grinding operation. It has the advantages of online pre-processing and quick mold change, eliminating the need to add a separate grinding station, shortening the production line length, and making the replacement of the grinding block 29 simple and time-saving, thus improving equipment operation and maintenance efficiency and continuous production stability.

[0024] Example 2: Figures 1 to 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the auxiliary component includes an auxiliary box 214 fixedly attached to the lower surface of the fixed box 2, a positioning tube 217 fixedly attached to one side of the auxiliary box 214, the positioning tube 217 communicating with the auxiliary box 214, and a plurality of spray holes opened on the inner wall of the positioning tube 217, which can spray a base coat liquid onto the thread grooves on the surface of the raw yarn; the output end of the fixed motor 21 is drivenly connected to a transmission belt 212, an auxiliary plate 215 is fixedly attached to one side of the auxiliary box 214, a connecting shaft 213 is rotatably connected to the auxiliary plate 215, the connecting shaft 213 is drivenly connected to the transmission belt 212, and a bottom end of the connecting shaft 213 is fixedly attached to... A cone plate 219 is elastically connected inside the cam 216 and the auxiliary box 214. The cam 216 squeezes the cone plate 219 to connect the auxiliary box 214 and the positioning tube 217 for spraying the base coat liquid. The auxiliary box 214 has a positioning groove 218 inside, and a compression spring 220 is fixed to the inner wall of the positioning groove 218. One end of the compression spring 220 is fixed to the cone plate 219. The surface of the cone plate 219 has a positioning hole 221. The auxiliary box 214 also has a connecting groove 222 inside. After the cone plate 219 is squeezed into the positioning groove 218 by the cam 216, the positioning hole 221 is aligned with the connecting groove 222, and at the same time, it connects to the storage cavity inside the auxiliary box 214.

[0025] Specifically, while the grinding block 29 is performing pretreatment, the fixed motor 21 will synchronously drive the transmission belt 212 to perform transmission work. The synchronous transmission work of the transmission belt 212 will drive the cam 216 at the bottom of the connecting shaft 213 to rotate. The rotation of the cam 216 will squeeze the cone plate 219 into the positioning groove 218. After the cone plate 219 is squeezed into the positioning groove 218, the positioning hole 221 on the surface of the cone plate 219 will be aligned with the slot hole at one end of the connecting groove 222 and will be connected to the storage cavity inside the auxiliary box 214. The solid liquid in the storage cavity will flow into the positioning tube 217 under pressure and be sprayed out through several spray holes on the inner wall of the positioning tube 217, spraying into the thread groove of the original wire to assist in the lubrication application work. The cam 216 rotates with the transmission belt 212 to periodically squeeze the cone plate 219, thereby achieving intermittent quantitative supply of pre-coated base liquid. The liquid is sprayed into the groove of the original wire thread through the spray hole. The pre-coated liquid fills the groove to form a bonding base. In combination with the spiral pattern, it greatly enhances the adhesion of the lubricating powder, reduces powder shedding, and automatically controls the liquid spraying to be uniform, effectively improving the subsequent drawing lubrication effect and reducing wire breakage and raw material loss.

[0026] Working principle: First, during the drawing of the raw filament, one end of the filament passes through the fixed box 2, the powder coating frame 15, and the fixed roller 16 before being drawn. During the drawing process, the fixed motor 21 on the upper surface of the fixed box 2 is activated. The activation of the fixed motor 21 drives the first gear 210 at its output end to rotate. The rotation of the first gear 210 drives the second gear 211, which in turn drives the grinding block 29 inserted inside to rotate. The rotating grinding block 29 grinds a threaded groove on the circumference of the raw filament. After the pretreatment, the raw filament continues to be drawn, passing through the powder coating frame 15 for powder coating. After powder coating, the drawing process is carried out. After the grinding block 29 has finished grinding... During the replacement process, first rotate the connecting magnetic block 27 that is locked at the top of the positioning rod 24 to release the locking of the positioning rod 24 by the connecting magnetic block 27 and the insert plate 28. As the grinding block 29 rotates, it will drive the positioning rod 24 to rotate synchronously. The positioning rod 24 is magnetically attracted by the connecting magnetic block 27 and locked by the insert plate 28, thus driving the connecting magnetic block 27 to slide synchronously along the rotating groove 22. A sliding rod 23 is slidably connected in the rotating groove 22. Two connecting rods 26 are rotatably connected to the positioning block 25 at the top of the sliding rod 23. The connecting magnetic block 27 is fixed to the ends of the two connecting rods 26. Therefore, when replacing the grinding block 29, first contact the limit of the connecting magnetic block 27, and then pull the positioning rod 24 to remove the grinding block 29 for replacement. By simultaneously grinding the threaded grooves on the surface of the raw wire before drawing, the fixed motor 21 drives the first gear 210 and the second gear 211 to drive the grinding block 29 to rotate, thus processing continuous spiral grooves on the outer periphery of the raw wire. This improves the adhesion and bonding strength of the lubricating powder, effectively reduces powder shedding after powdering, and reduces problems such as wire breakage and wire scratches during drawing. At the same time, the grinding block 29 adopts a double limiting structure of magnetic attraction and insert plate 28. During disassembly, only the top connecting magnetic block 27 needs to be rotated to release the locking of the positioning rod 24, without the need for complicated disassembly tools. When the grinding block 29 rotates, the positioning rod 24 and the sliding component can slide synchronously along the rotating groove 22 without interfering with the grinding operation. It has the advantages of online pre-processing and quick mold change, without the need to add a separate grinding station, shortening the production line length. The operation of replacing the grinding block 29 is simple and time-saving, improving the equipment operation and maintenance efficiency and continuous production stability. In addition, while the grinding block 29 is performing pretreatment, the fixed motor 21 will synchronously drive the transmission belt 212 to perform transmission work. The synchronous transmission work of the transmission belt 212 will drive the cam 216 at the bottom of the connecting shaft 213 to rotate. The rotation of the cam 216 will squeeze the cone plate 219 into the positioning groove 218. After the cone plate 219 is squeezed into the positioning groove 218, the positioning hole 221 on the surface of the cone plate 219 will be aligned with the slot hole at one end of the connecting groove 222 and will be connected to the storage cavity inside the auxiliary box 214. The solid liquid in the storage cavity will flow into the positioning tube 217 under pressure and be sprayed out through several spray holes on the inner wall of the positioning tube 217, spraying into the thread groove of the raw wire to assist in the lubrication application work. The cam 216 rotates with the transmission belt 212 to periodically squeeze the cone plate 219, thereby achieving intermittent quantitative supply of pre-coated base liquid. The liquid is sprayed into the groove of the original wire thread through the spray hole. The pre-coated liquid fills the groove to form a bonding base. In combination with the spiral pattern, it greatly enhances the adhesion of the lubricating powder, reduces powder shedding, and automatically controls the liquid spraying to be uniform, effectively improving the subsequent drawing lubrication effect and reducing wire breakage and raw material loss.

The rotation of the first gear (210) drives the second gear (211) to rotate. The rotation of the second gear (211) drives the grinding block (29) inserted inside to rotate. The rotating grinding block (29) grinds a threaded groove on the circumference of the raw filament. After the pretreatment is completed, the raw filament continues to be drawn so that it passes through the powder coating frame (15) for powder coating. After the powder coating is completed, the drawing process is carried out.

9. The stainless steel alloy grounding wire pulling device according to claim 4, characterized in that: After the grinding block (29) is polished, during the replacement process, first rotate the connecting magnetic block (27) that is locked at the top of the positioning rod (24) to release the locking of the connecting magnetic block (27) and the insert plate (28) to the positioning rod (24). During the rotation of the grinding block (29), it will drive the positioning rod (24) to rotate synchronously. The positioning rod (24) is magnetically attracted by the connecting magnetic block (27) and locked by the insert plate (28), so it drives the connecting magnetic block (27) to slide synchronously along the rotating groove (22). A sliding rod (23) is slidably connected in the rotating groove (22). Two connecting rods (26) are rotatably connected on the positioning block (25) at the top of the sliding rod (23). The connecting magnetic block (27) is fixed to the ends of the two connecting rods (26). Therefore, when replacing the grinding block (29), first contact the limit of the connecting magnetic block (27), and then pull the positioning rod (24) to take out the grinding block (29) for replacement.

10. A stainless steel alloy grounding wire pulling device according to claim 7, characterized in that: While the grinding block (29) is performing pretreatment, the fixed motor (21) will synchronously drive the transmission belt (212) to perform transmission. The synchronous transmission of the transmission belt (212) will drive the cam (216) at the bottom of the connecting shaft (213) to rotate. The rotation of the cam (216) will squeeze the cone plate (219) into the positioning groove (218). After the cone plate (219) is squeezed into the positioning groove (218), the positioning hole (221) on the surface of the cone plate (219) will be aligned with the slot hole at one end of the connecting groove (222) and will be connected to the storage cavity inside the auxiliary box (214). The solid liquid in the storage cavity flows into the positioning tube (217) under pressure and is sprayed out through several spray holes on the inner wall of the positioning tube (217) into the thread groove of the original wire to assist in the lubrication application.
