Abstract
Description
Technical Field
[0001] This invention relates to the field of steel wire processing technology, specifically to a multi-station drawing and trimming composite processing device and process for irregularly shaped steel wires. Background Technology
[0002] During the production and processing of steel wire, the diameter needs to be reduced and the cross-sectional shape needs to be changed through the drawing process. During multiple drawing and extrusion processes, the steel wire is affected by the release of stress or excessive deformation of the material itself, resulting in cracks or metal protrusions on the surface. Existing drawing equipment lacks a real-time mechanical detection structure between drawing stations. Steel wires with surface defects continue to enter the next die hole without being detected, resulting in an increase in the number of scraps. Furthermore, the hard protrusions on the surface cause direct physical damage to the inner hole of the subsequent die.
[0003] In addition, traditional wire drawing processing equipment uses an unwinding mechanism to draw out the coiled wire and then directly feeds it into the drawing die for extrusion forming. The coiled wire has an initial curvature after being unwound. When the wire with the curvature directly enters the drawing die hole, there is a deviation in the contact surface between the wire and the inner wall of the die hole, which leads to excessive force on one side of the die. Uneven force exacerbates the wear of the inner hole of the die and causes deviation in the size of the drawn wire.
[0004] Drawing and extrusion are accompanied by high temperatures and the generation of metal debris. The processing area relies on cooling lubricant for cooling. Traditional coolant recovery structures lack graded filtration components for metal debris. The liquid mixed with debris is extracted again and sprayed onto the surface of the steel wire. Hard metal debris is carried into the die orifice and directly scratches the surface of the steel wire under extrusion. In addition, burrs remain on the edges of the drawn and shaped steel wire. Existing equipment does not have a synchronous trimming and cutting structure before winding. A second independent cutting process for the finished steel wire increases the overall production process. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a multi-station drawing and trimming composite processing device and process for irregularly shaped steel wires, which solves the technical problems of difficulty in real-time mechanical detection of surface defects during steel wire drawing and uneven stress on the drawing die caused by the initial bending of the steel wire.

The lower surface of the positive V-shaped clamping seat is rotatably connected to a connecting seat via a bearing, and the upper surface of the inverted V-shaped clamping seat is rotatably connected to another connecting seat via a bearing. An installation rod is fixedly connected to one side of the inverted V-shaped clamping seat, and a second ball bearing and a third ball bearing are respectively embedded on the opposite sides of the positive V-shaped clamping seat and the inverted V-shaped clamping seat.
[0015] Preferably, both the positive V-shaped clamping seat and the inverted V-shaped clamping seat are fixedly connected to slide rods, and the surfaces of the two sets of slide rods are jointly fitted with an adjusting plate. The adjusting plate is slidably connected to the slide rods, and the interior of the adjusting plate is provided with an opening.

[0018] Preferably, the circulation mechanism includes a collection pool fixedly disposed inside the workbench. A drainage groove is provided on the top of the workbench.

An extrusion plate is fixedly connected to the output end of each electric push rod. A rubber bladder is provided below each extrusion plate. An extraction pipe is connected to the bottom of each rubber bladder. The bottom end of each extraction pipe extends into the collection pool. A spray pipe is connected to one side of each rubber bladder.
[0019] Preferably, a first filter screen and a second filter screen are fixedly connected in sequence inside the collection pool.

The trimming mechanism includes a slider that is slidably connected inside the slide groove. A second motor is fixedly connected to the top of the slider. An insert rod is inserted into the inside of the slider. The bottom end of the insert rod is in contact with and fixed to the top of the workbench. A first grinding wheel and a second grinding wheel are fixedly connected to the output end of the second motor.
[0020] A second aspect of the present invention also provides a multi-station drawing and trimming composite processing technology for irregularly shaped steel wires, the production process including the following steps:
[0021] S1. Start the first motor to drive the take-up roller to rotate, draw the steel wire out from the unwind roller and pull it to the top of the workbench, open the box door to clean the impurities intercepted inside the collection pool;
[0022] S2. The steel wire enters the smoothing mechanism, passes over the fixed plate and pushes open the baffle. The magnet uses magnetic force to make the baffle stick to the surface of the steel wire. The adjusting plate, which is slidably sleeved on the surface of the slide rod, changes the distance between the staggered positive V-shaped clamping seats and the inverted V-shaped clamping seats, so that the steel wire passing through the opening is straightened by the physical compression of the second ball and the third ball.
[0023] S3. The straightened steel wire travels along the surface of the workbench. The steel wire passes through the drawing holes in the first drawing die, the second drawing die, and the third drawing die, which are fitted and fixed inside the first die holder, the second die holder, and the third die holder. The steel wire is drawn thinner by extrusion through multiple holes. The threaded rod is rotated to adjust the die fit.
[0024] S4. During the drawing process, the steel wire passes through the limiting ring. If the surface of the steel wire cracks and produces a protrusion or crack, the deformed part of the surface will squeeze the universal ball and push the connecting rod, causing the bearing seat to slide on the worktable supported by the first ball. At this time, the counterweight plate uses the bearing to move in the bearing seat and overcome the spring force, causing the metal sheets to collide with each other and produce mechanical noise.
[0025] S5. During the drawing process, the electric push rod drives the extrusion plate to reciprocate to compress and release the rubber bladder, drawing out the liquid in the collection tank through the extraction pipe and spraying it onto the feed end through the spray pipe. The waste liquid falls back into the collection tank along the diversion channel, and is guided and intercepted by the first and second filter screens set at an inclination. The fine impurities are adsorbed by the adsorption cotton to achieve liquid circulation.
[0026] S6. After being drawn, the steel wire travels to the trimming mechanism. The second motor is started to drive the first and second grinding wheels to rotate. The slider moves in the groove and is fixed by the insertion rod. The cutting depth of the double grinding wheels on the edge of the steel wire is adjusted. The processed steel wire is finally wound on the take-up roller for collection.
[0027] This invention provides a multi-station drawing and trimming composite processing device and process for irregularly shaped steel wires. It has the following beneficial effects:
[0028] 1. This invention uses a pull-out detection mechanism. The steel wire passes through the limiting ring and the universal ball is attached to the surface of the steel wire. When there is a protrusion or crack on the surface of the steel wire, the deformed part of the surface squeezes the universal ball to deflect and pushes the connecting rod, which drives the bearing seat to slide on the worktable. The counterweight plate follows the movement of the bearing seat and overcomes the spring force to generate displacement, causing the metal sheets to collide with each other and make a sound. The physical linkage of the mechanical parts directly provides a collision sound prompt.
[0029] 2. The present invention sets a smoothing mechanism on the worktable. The steel wire to be processed passes through the opening of the adjusting plate. The sliding adjusting plate changes the distance between the staggered positive V-shaped clamping seats and the inverted V-shaped clamping seats, so that the second ball and the third ball squeeze the passing steel wire. Before the steel wire enters the drawing die, the initial bending degree of the steel wire is reduced, and it is kept in a straight state to reduce the uneven force caused by the bent steel wire entering the drawing hole.
[0030] 3. This invention uses a circulation mechanism where an electric push rod drives a compression plate to reciprocate, alternately compressing and releasing the rubber bladder. The cooling and lubricating fluid in the collection tank is extracted through an extraction pipe and sprayed onto the feed inlet of the drawing hole through a spray pipe. The waste liquid flows back to the collection tank along the diversion channel and passes through the first and second inclined filter screens to intercept metal debris. Fine impurities in the waste liquid are absorbed by absorbent cotton. The filtered cooling and lubricating fluid is retained at the bottom of the collection tank for repeated extraction.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Please see the appendix Figure 1 To be continued Figure 8This invention provides a multi-station drawing and trimming composite processing device for irregularly shaped steel wires, including a workbench 1. A door 2 is hinged to the front of the workbench 1. A first support frame 3 and a second support frame 11 are arranged on one side above the workbench 1. The first support frame 3 is used to install the unwinding roller 4 and convey the steel wire, and the second support frame 11 is used to install the winding roller 12 and collect the steel wire. A smoothing mechanism 19, a first mold base 9, a second mold base 14, and a third mold base 16 are arranged sequentially along the direction of the steel wire's travel on the top of the workbench 1. The drawing detection mechanism 18 and the trimming mechanism 21, and the smoothing mechanism 19 are used to straighten the steel wire by squeezing. The first mold base 9, the second mold base 14 and the third mold base 16 are fitted with molds for drawing the steel wire through the drawing hole. The drawing detection mechanism 18 is used to detect the flatness of the steel wire surface and generate an audible prompt. The trimming mechanism 21 is used to cut the edge of the steel wire. A circulation mechanism 20 is set between the inside of the worktable 1 and the top of the mold base. The circulation mechanism 20 is used to extract and filter the cooling lubricant.
[0042] Specifically, when the device is working, the first motor 13 is started to drive the take-up roller 12 to rotate, and the steel wire to be processed is led out from the unwinding roller 4 and pulled to the top of the worktable 1. The steel wire enters the smoothing mechanism 19, is physically squeezed to remove the bend and straighten it. Then the steel wire moves along the surface of the worktable 1 and passes through the drawing holes 17 in the first mold seat 9, the second mold seat 14 and the third mold seat 16 fixed on the surface of the worktable 1 in sequence. After passing through the drawing holes 17, the diameter is reduced. The drawing detection mechanism 18 performs contact detection on the surface of the steel wire in motion. When it encounters a protrusion or crack, it drives the internal components to move and makes the metal sheet 187 collide and make a sound. At the same time, the circulation mechanism 20 draws and sprays cooling lubricant and filters and intercepts the waste liquid. The drawn steel wire is ground and cut by the trimming mechanism 21. The finished steel wire is finally wound on the take-up roller 12 and collected.
[0043] Please see the appendix Figure 2 and attached Figure 3In a preferred embodiment of the present invention, the smoothing mechanism 19 includes a fixed plate 191 fixedly connected to the top of the workbench 1. A positive V-shaped clamping seat 192 and an inverted V-shaped clamping seat 193 are provided on one side of the fixed plate 191. A through plate 1914 is fixedly connected to the surfaces of the positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193. A rotating shaft 1912 is fixedly connected to the end of the through plate 1914. A baffle 1911 is rotatably connected to the outer surface of the rotating shaft 1912. A magnet 1913 is embedded in the side of the baffle 1911. The positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193 are arranged alternately. The lower surface of the inverted V-shaped clamping seat 193 is rotatably connected to a connecting seat 196 via a bearing. The upper surface of the inverted V-shaped clamping seat 193 is rotatably connected to another connecting seat 196 via a bearing. An installation rod 194 is fixedly connected to one side of the inverted V-shaped clamping seat 193. The opposite sides of the positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193 are respectively inlaid with a second ball bearing 195 and a third ball bearing 197. The surfaces of both the positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193 are fixedly connected to slide rods 199. An adjusting plate 198 is sleeved on the surfaces of the two sets of slide rods 199. The adjusting plate 198 is slidably connected to the slide rods 199. An opening 1910 is opened inside the adjusting plate 198.
[0044] Specifically, the steel wire passes over the fixed plate 191, through the through plate 1914, and pushes open the baffle 1911. The magnet 1913 attracts the wire and makes the baffle 1911 adhere to the surface of the steel wire, pushing the adjusting plate 198 sleeved on the surface of the slide rod 199, changing the relative distance between the positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193, so that the steel wire passing through the opening 1910 is squeezed by the staggered second ball 195 and the third ball 197, thus straightening the moving steel wire.
[0045] Please see the appendix Figure 4 In a preferred embodiment of the present invention, a first mold base 9, a second mold base 14, and a third mold base 16 are sequentially fixedly connected to the top of the workbench 1 and between the smoothing mechanism 19 and the second support frame 11. A first drawing die 5, a second drawing die 6, and a third drawing die 7 are fitted inside the first mold base 9, the second mold base 14, and the third mold base 16. A drawing hole 17 is opened inside the first drawing die 5, the second drawing die 6, and the third drawing die 7. A threaded rod 8 is threadedly connected to one side of the first mold base 9, the second mold base 14, and the third mold base 16.
[0046] Specifically, the straightened steel wire moves along the surface of the workbench 1 and passes sequentially through the first drawing die 5, the second drawing die 6, and the third drawing die 7, which are fitted inside the first die holder 9, the second die holder 14, and the third die holder 16. The steel wire is physically drawn through the drawing hole 17 to reduce its diameter. The threaded fit between the threaded rod 8 and the die holder can be adjusted by rotating the threaded rod 8 for fine-tuning.
[0047] Please see the appendix Figure 5 In a preferred embodiment of the present invention, the pull-out detection mechanism 18 includes a limiting ring 181. A connecting rod 182 is movably connected to the inner side of the limiting ring 181 via a universal ball 185. A bearing seat 183 is fixedly connected to the end of the connecting rod 182 away from the limiting ring 181. A first ball 186 is rotatably connected to the bottom of the bearing seat 183. The bottom of the first ball 186 slides in contact with the top of the worktable 1. A spring 188 is fixedly connected inside the bearing seat 183. A counterweight plate 184 is fixedly connected to one end of the spring 188. The counterweight plate 184 is movably connected to the inside of the bearing seat 183 via a bearing. A metal sheet 187 is fixedly connected to one side of the counterweight plate 184.
[0048] Specifically, the steel wire passes through the limiting ring 181, the universal ball 185 at the end of the connecting rod 182 is attached to the surface of the steel wire, and the first ball 186 contacts the surface of the worktable 1. If the steel wire develops a protrusion or crack during its movement, the deformed part of the steel wire surface will squeeze the universal ball 185 and cause it to deflect, thereby pushing the connecting rod 182 and causing the bearing seat 183 to slide on the worktable 1 supported by the first ball 186. During this sliding displacement, the counterweight plate 184 moves relative to the bearing seat 183 against the elastic force of the spring 188, causing the metal sheets 187 on the counterweight plate 184 to collide with each other and produce a sound.
[0049] Please see the appendix Figure 6 and attached Figure 7 In a preferred embodiment of the present invention, the circulation mechanism 20 includes a collection pool 201 fixedly disposed inside the workbench 1. A drainage groove 10 is provided on the top of the workbench 1. An electric push rod 208 is fixedly connected to the top of the first mold base 9, the second mold base 14 and the third mold base 16. An extrusion plate 209 is fixedly connected to the output end of the electric push rod 208. A rubber bladder 206 is provided below the extrusion plate 209. An extraction tube 207 is connected to the bottom of the rubber bladder 206. The bottom end of the extraction tube 207 extends into the collection pool 201. A spray pipe 205 is connected to one side of the rubber bladder 206. A first filter screen 203 and a second filter screen 204 are fixedly connected in sequence inside the collection pool 201. The first filter screen 203 and the second filter screen 204 are both inclined. An absorbent cotton 202 is provided on one side of the second filter screen 204.
[0050] Specifically, the electric push rod 208 drives the extrusion plate 209 to perform linear reciprocating motion, alternately compressing and releasing the rubber bladder 206, drawing out the cooling lubricant inside the collection tank 201 through the extraction pipe 207, and spraying it onto the feed end of the drawing hole 17 through the spray pipe 205. The waste liquid flows into the collection tank 201 along the diversion channel 10, flows through the inclined first filter screen 203 and second filter screen 204 to intercept large metal fragments, and then the absorbent cotton 202 absorbs the fine impurities in the waste liquid. The filtered liquid is retained at the bottom of the collection tank 201 to complete the circulation.
[0051] Please see the appendix Figure 8 In a preferred embodiment of the present invention, a slide groove 15 is provided on the top of the workbench 1 and between the third mold base 16 and the second support frame 11. A trimming mechanism 21 is provided above the slide groove 15. The trimming mechanism 21 includes a slider 211 slidably connected inside the slide groove 15. A second motor 212 is fixedly connected to the top of the slider 211. A rod 213 is inserted into the inside of the slider 211. The bottom end of the rod 213 contacts and is fixed to the top of the workbench 1. A first grinding wheel 214 and a second grinding wheel 215 are fixedly connected to the output end of the second motor 212.
[0052] Specifically, the second motor 212 is started to drive the first grinding wheel 214 and the second grinding wheel 215 to rotate. The two sets of grinding wheels contact the edge of the steel wire to cut the burrs. The slider 211 is moved in the groove 15 to change the distance between the grinding wheel and the steel wire. Then the bottom end of the insert rod 213 is pressed down to contact the top of the worktable 1 to fix the position of the slider 211, thereby adjusting the cutting depth of the first grinding wheel 214 and the second grinding wheel 215 on the steel wire.
[0053] This invention also provides a multi-station drawing and trimming composite processing technology for irregularly shaped steel wires. Using the aforementioned multi-station drawing and trimming composite processing device for irregularly shaped steel wires, the processing technology includes the following steps:
[0054] S1. Start the first motor 13 to drive the take-up roller 12 to rotate, draw the steel wire out from the unwind roller 4 and pull it to the top of the workbench 1, open the box door 2 to clean the impurities intercepted inside the collection pool 201.
[0055] S2. The steel wire enters the smoothing mechanism 19, passes over the fixed plate 191 and pushes open the baffle 1911. The magnet 1913 attracts and makes the baffle 1911 adhere to the surface of the steel wire. The adjusting plate 198, which is slidably sleeved on the surface of the slide rod 199, changes the distance between the positive V-shaped clamping seat 192 and the inverted V-shaped clamping seat 193, so that the steel wire passing through the opening 1910 is straightened by the alternating compression of the second ball 195 and the third ball 197.
[0056] S3. The steel wire passes through the drawing holes 17 of the first drawing die 5, the second drawing die 6, and the third drawing die 7, which are fixed inside the first die holder 9, the second die holder 14, and the third die holder 16 in sequence. It is squeezed and drawn thinner. The threaded rod 8 is rotated to adjust the fit.
[0057] S4. During the drawing process, the steel wire passes through the limiting ring 181. When the surface of the steel wire produces a protrusion or crack, it squeezes the universal ball 185, pushes the connecting rod 182 to drive the bearing seat 183 to slide on the worktable 1. The counterweight plate 184 moves within the bearing seat 183 against the elastic force of the spring 188, causing the metal sheets 187 to collide with each other and produce mechanical noise.
[0058] S5. The electric push rod 208 drives the extrusion plate 209 to reciprocate to compress and release the rubber bladder 206, drawing out the liquid in the collection tank 201 through the extraction pipe 207 and spraying it onto the feed end through the spray pipe 205. The waste liquid flows into the collection tank 201 along the diversion channel 10, where it is intercepted by the inclined first filter screen 203 and second filter screen 204 to intercept metal debris, and the fine impurities are adsorbed by the adsorption cotton 202.
[0059] S6. After being drawn, the steel wire travels to the underside of the trimming mechanism 21. The second motor 212 is started to drive the first grinding wheel 214 and the second grinding wheel 215 to rotate. The slider 211 moves in the groove 15 and the insertion rod 213 is inserted to fix the position. The cutting depth of the grinding wheel is adjusted, and the finished steel wire is finally wound on the take-up roller 12.
[0060] Although embodiments of the 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 invention, the scope of which is defined by the appended description and its equivalents.

10. A multi-station drawing and trimming composite processing technology for irregularly shaped steel wires, characterized in that, Using the multi-station drawing and trimming composite processing device for irregularly shaped steel wires according to any one of claims 1-9, the processing technology includes the following steps: S1. Start the first motor (13) to drive the take-up roller (12) to rotate, and pull the steel wire out from the unwinding roller (4) and pull it to the top of the workbench (1). Open the box door (2) to clean the impurities intercepted inside the collection pool (201). S2. The steel wire enters the smoothing mechanism (19), passes over the fixed plate (191) and pushes open the baffle (1911). The magnet (1913) uses magnetic force to make the baffle (1911) stick to the surface of the steel wire. The adjusting plate (198) that is slidably sleeved on the surface of the slide rod (199) changes the distance between the staggered positive V-shaped clamping seat (192) and the inverted V-shaped clamping seat (193), so that the steel wire passing through the opening (1910) is straightened by the physical compression of the second ball (195) and the third ball (197). S3. The straightened steel wire travels along the surface of the workbench (1). The steel wire passes through the drawing holes (17) in the first drawing die (5), the second drawing die (6) and the third drawing die (7) that are fitted and fixed inside the first die holder (9), the second die holder (14) and the third die holder (16). The steel wire is drawn thinner by extrusion through multiple holes. The threaded rod (8) is rotated to adjust the die fit. S4. During the drawing process, the steel wire passes through the limiting ring (181). If the surface of the steel wire cracks and produces a protrusion or crack, the deformed part of the surface will squeeze the universal ball (185) and push the connecting rod (182), causing the bearing seat (183) to slide on the worktable (1) supported by the first ball (186). At this time, the counterweight plate (184) uses the bearing to move in the bearing seat (183) and overcome the elastic force of the spring (188), causing the metal sheets (187) to collide with each other and produce mechanical noise. S5. During the drawing process, the electric push rod (208) drives the extrusion plate (209) to reciprocate to compress and release the rubber bladder (206), and the liquid in the collection tank (201) is extracted through the extraction pipe (207) and sprayed onto the feed end by the spray pipe (205). The waste liquid falls back into the collection tank (201) along the diversion channel (10), and is guided and intercepted by the inclined first filter screen (203) and second filter screen (204). The liquid is circulated by the adsorption cotton (202) adsorbing the fine impurities. S6. The drawn steel wire travels to the trimming mechanism (21). The second motor (212) is started to drive the first grinding wheel (214) and the second grinding wheel (215) to rotate. The slider (211) moves in the groove (15) and the plug rod (213) is inserted and fixed. The cutting depth of the double grinding wheel on the edge of the steel wire is adjusted. The processed steel wire is finally wound on the take-up roller (12) for collection.
