Description

Technical Field

[0001] This invention relates to the field of stainless steel wire production, specifically to a drawing device for stainless steel wire production. Background Technology

[0002] A stainless steel wire drawing machine, also known as a wire drawing machine or wire drawing machine, is a device that processes metal wire into fine stainless steel wire of the required specifications through mechanical traction and die stretching. Wire drawing machines are suitable for processing different metal materials, such as high, medium, and low carbon steel wire, stainless steel wire, copper wire, alloy copper wire, aluminum alloy wire, etc. The working principle of the wire drawing machine is to draw thick metal wire into the required fine wire through mechanical traction and die stretching.

[0003] During the drawing process, lubricating powder needs to be coated on the surface of the stainless steel wire to reduce frictional resistance, minimize die wear, and prevent scratches on the wire surface. Currently, most small and medium-sized wire drawing production lines manually add lubricating powder to the powder box. Operators need to frequently check the powder box level and manually replenish the powder at irregular intervals. Furthermore, the lubricating dust generated during the drawing process disperses throughout the workshop, resulting in a poor working environment. Therefore, a drawing device for stainless steel wire production is needed. Summary of the Invention

[0012] Preferably, the bottom of the support frame is equipped with a drive shaft driven by a motor. The drawing drum and the collecting drum are driven to rotate by the drive shaft. The drive shaft is connected to the reciprocating threaded rod through a synchronous belt and synchronous pulley. The end of the reciprocating threaded rod is connected to a drive shaft through two meshing bevel gears.

[0013] Preferably, the top end of the first drive shaft is connected to the rotating shaft via two meshing bevel gears, the top end of the first drive shaft is connected to the second drive shaft via two meshing gears, and the top end of the second drive shaft is connected to the camshaft via two meshing gears.

[0014] Preferably, the top of the support frame is equipped with multiple expansion interfaces for installing auxiliary wire drawing structures.

[0015] Working principle: Before use, open the top cover of the filling box and place the lubricating powder bag horizontally into the inner box. The tip of the bag cutter will pierce the bag. Under gravity, the lubricating powder bag will press the lifting plate down along the inner wall of the box. The spring rods around the lifting plate are compressed. As the lifting plate descends, the connecting rods hinged at the bottom on both sides move down accordingly. The bottom of the connecting rods pushes the bag cutter along the guide block to both sides, cutting open the bottom of the bag. The lubricating powder will pass through the strainer in the middle of the lifting plate into the storage compartment for temporary storage. After the lubricating powder is discharged, the weight of the bag and its contents is reduced, and the elasticity of the spring rods pushes the lifting plate back up. When the lifting plate rises, the connecting rods pull the bag cutter outward along the guide block to reset, ready for the next filling. The cut empty bag is left above the strainer and can be removed and discarded by the operator during the next filling.

[0016] After the equipment is started, the bottom drive motor drives the drive shaft to rotate. The drive shaft drives the reciprocating threaded rod to rotate through the synchronous belt and synchronous pulley. The end of the reciprocating threaded rod drives the drive shaft to rotate through the bevel gear transmission. The top of the drive shaft drives the rotating shaft to rotate through the bevel gear transmission. The rotating shaft drives the turntable to rotate through the bevel gear transmission. The connecting block rotating on the inner and outer circumference of the turntable moves eccentrically with the turntable. The top of the connecting block is rotatably connected to the bottom of the storage bin. The eccentric motion is converted into the reciprocating vibration of the storage bin. Under the constraint of the shock absorber, the storage bin vibrates at a small amplitude and high frequency, continuously shaking off the internal lubricating powder. The powder enters the discharge port through the bottom discharge port and the telescopic hose, preventing the lubricating powder on the inner wall from clumping.

[0017] The top of drive shaft one drives drive shaft two to rotate via gear transmission. The top of drive shaft two drives camshaft to rotate via gear transmission. The cam disc at the bottom of the camshaft rotates with it. The protruding part of the cam disc abuts against the outer wall of the front side of the switch frame, pushing the switch frame to move horizontally along the bottom of the filling box. The cam disc continues to rotate. The switch frame moves back and forth under the combined action of the cam disc and the telescopic rod. The discharge port fixed on the inner wall of the switch frame swings back and forth above the powder box with the switch frame, evenly sprinkling the lubricating powder into the powder box. The electric push rod drives the movable block to move horizontally, which can clamp or loosen the telescopic hose connecting the discharge port and the storage bin, and start or stop the powder supply as needed.

[0018] The active shaft synchronously drives the drawing drum at the drawing station and the collecting drum at the winding station to rotate synchronously. The stainless steel wire passes sequentially through the guide wheels, powder box and drum at each station of the support frame. The stainless steel wire is guided into the powder box by the first guide wheel. Inside the powder box, it passes through the sprinkled lubricating powder to complete the surface coating. The stainless steel wire coated with lubricating powder enters the wire drawing die box and passes through the wire drawing die for drawing and shaping. The drawing drum rotates under the drive of the active shaft, applying a drawing force to the stainless steel wire, causing the stainless steel wire to gradually become thinner in the wire drawing die. After multiple drawing processes, the finished stainless steel wire is guided to the winding station by the second guide wheel. The collecting drum rotates under the drive of the active shaft and winds the finished stainless steel wire into a coil.

[0019] During the drawing process, the lubricating dust that escapes is drawn into the dust collection chamber by the negative pressure airflow generated by the negative pressure fan. The dust-laden airflow passes through the filter plate, and the solid lubricating powder is intercepted and adsorbed on the surface of the filter plate. The drive shaft drives the reciprocating threaded rod to rotate through the synchronous belt and synchronous pulley. The reciprocating threaded rod drives the brush to move back and forth along its axis. The brush bristles scrape off the solid lubricating powder adsorbed on the surface of the filter plate during the reciprocating motion. The scraped lubricating powder falls into the collection box that is slidably connected at the bottom of the dust collection chamber. The operator periodically removes the collection box to recycle or centrally process the collected lubricating powder.

[0020] This invention provides a drawing device for stainless steel wire production. It has the following advantages: 1. This invention achieves automatic cutting and filling of lubricating powder packaging bags through a bag-cutting component. The operator only needs to put the entire bag of lubricating powder into the inner box. The weight of the packaging bag presses against the lifting plate, which triggers the bag-cutting knife to automatically cut the bottom of the bag. The powder falls through the strainer into the storage bin for temporary storage. After the powder is emptied, the lifting plate automatically resets. The entire filling process does not require manual bag opening and powder emptying, reducing dust and manual intervention, and realizing the sealed automatic filling of lubricating powder.

[0021] 2. This invention prevents powder from bridging by reciprocating vibration of the storage bin. At the same time, the discharge port swings back and forth above the powder box to evenly sprinkle lubricating powder into the powder box. The electric push rod drives the movable block to control the opening and closing of the discharge channel at any time, supplying powder as needed and avoiding powder waste.

[0022] 3. This invention uses a negative pressure fan to draw the lubricating dust emitted during the pulling process into the dust collection chamber, which can suppress dust pollution in the workshop and improve the working environment. The filter plate intercepts and adsorbs solid lubricating powder, and the brush automatically scrapes the powder off the filter plate surface into the collection box under the drive of the reciprocating threaded rod. Operators only need to periodically remove the collection box to recover the powder. The frequency of disassembling and cleaning the filter screen during machine shutdown is low, realizing online self-cleaning of the dust collection filter screen and ensuring long-term stable dust removal effect.

[0025] The technical solutions of 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.

[0026] Example: This invention provides a drawing device for stainless steel wire production, comprising: Please see the appendix Figure 1 Appendix Figure 2 The support frame 1 has a top frame 2 welded and fixed to its top. The support frame 1 is divided into a drawing station and a winding station. A drawing drum 3 is rotatably connected to the top of the drawing station, and a collecting drum 4 is rotatably connected to the top of the winding station. A guide wheel 6 for guiding the stainless steel wire is installed on the top of the top frame 2 through a guide wheel frame. The front side of the filling box 7 is fixed to the front support arm of the top frame 2 by bolts. Multiple expansion interfaces 37 are installed on the top of the support frame 1 for installing auxiliary wire drawing structures.

[0027] Specifically, the support frame 1 is made of welded steel profiles and serves as the support base for the entire device. Its top is divided into two working areas along the direction of stainless steel wire travel: a drawing station and a winding station. The drawing drum 3 in the drawing station can apply a drawing force to the stainless steel wire, causing it to gradually become thinner in the drawing die 13. The collecting drum 4 in the winding station can wind the finished stainless steel wire into a coil. The top frame 2 is welded and fixed to the top of the support frame 1. A guide wheel 6 is installed on the top of the top frame through a guide wheel frame to guide the stainless steel wire into the drawing station. The filling box 7 is bolted and fixed to the front support arm of the top frame 2 for automatic powder supply to the powder box 5. The expansion interface 37 is distributed on the top of the support frame 1 and is used to install hooks, tension wheels, and other auxiliary wire drawing structures according to processing requirements.

[0028] Please see the appendix Figure 2 Appendix Figure 11 and attached Figure 14 The bottom of the support frame 1 is equipped with a drive shaft 11 driven by a motor. The drawing drum 3 and the collecting drum 4 are driven to rotate by the drive shaft 11. The drive shaft 11 is connected to the reciprocating threaded rod 34 through a synchronous belt and synchronous pulley. The end of the reciprocating threaded rod 34 is connected to a drive shaft 16 through two meshing bevel gears. The top of the drive shaft 16 is connected to the rotating shaft 21 through two meshing bevel gears. The top of the drive shaft 16 is connected to a drive shaft 27 through two meshing gears. The top of the drive shaft 27 is connected to the camshaft 28 through two meshing gears.

[0029] Specifically, after the equipment is started, the bottom drive motor drives the drive shaft 11 to rotate. The two rolls at the top of the drawing station and the winding station are driven to rotate synchronously by the bottom drive shaft 11. The rotation of the drive shaft 11 will drive the worm gear at the bottom of the roll to rotate and will be lubricated through the lubrication structure. This structure is existing technology and is not within the protection scope of this invention, so it will not be described in detail. At the same time, the drive shaft 11 drives the reciprocating threaded rod 34 to rotate through the synchronous belt and synchronous pulley, and transmits the power to the dust collection component. The end of the reciprocating threaded rod 34 drives the transmission shaft 16 to rotate through the bevel gear transmission. When the transmission shaft 16 rotates, it will drive the rotating shaft 21 and the transmission shaft 27 to rotate synchronously.

[0030] Please see the appendix Figure 5 Appendix Figure 7 and attached Figure 9 An inner box 17 is fixedly connected to the top inner wall of the filling box 7. The inner wall of the inner box 17 is provided with a bag-cutting assembly for cutting open the lubricating powder packaging bag. The bag-cutting assembly includes a base plate 22 fixedly connected to the bottom of the inner box 17. A lifting plate 18 is slidably connected to the middle of the inner box 17. A mesh is embedded in the middle of the lifting plate 18. The lifting plate 18 is connected to the top of the base plate 22 by spring rods around its perimeter. Guide blocks 23 are fixedly connected to the top two sides of the base plate 22. A bag-cutting knife 19 is slidably assembled on the adjacent sides of the two guide blocks 23. Connecting rods 24 are hinged to the bottom of both sides of the lifting plate 18. The bottom end of the connecting rod 24 is hinged to the bag-cutting knife 19.

[0031] Specifically, open the top cover of the filling box 7, put the lubricating powder packaging bag into the inner box 17, and close the cover. The bottom of the packaging bag contacts the lifting plate 18, and at the same time, the bag cutter 19 pierces the packaging bag. Under the action of gravity, the packaging bag presses the lifting plate 18 to slide down along the inner wall of the inner box 17. When the lifting plate 18 descends, it drives the connecting rod 24 to push the bag cutter 19 in the guide block 23, so that the bag cutter 19 piercing the packaging bag moves to both sides to cut the packaging bag. The lubricating powder in the packaging bag falls into the storage chamber 20 through the strainer in the middle of the lifting plate 18. After the lubricating powder is discharged, the weight of the packaging bag is reduced, and the elasticity of the spring rod pushes the lifting plate 18 to return to its original position. The cut empty packaging bag is left above the strainer, and the operator can take it out and discard it for the next filling.

[0032] Please see the appendix Figure 6 and attached Figure 10 A storage chamber 20 is rotatably connected to the middle of the filling box 7. The top of the storage chamber 20 is connected to the bottom of the inner box 17 via a telescopic hose. A reciprocating vibration assembly for assisting the falling of lubricating powder is provided on the bottom left side of the storage chamber 20. The reciprocating vibration assembly includes a rotating shaft 21 located on the inner side of the bottom of the filling box 7 and rotatably connected to it via a bracket. The left end of the rotating shaft 21 is connected to a turntable 25 via two meshing bevel gears. A connecting block 26 is rotatably connected to the outer circumference of the inner side of the turntable 25. The top of the connecting block 26 is rotatably connected to the bottom of the storage chamber 20. The outer wall of the left side of the storage chamber 20 is connected to the inner wall of the filling box 7 via a shock-absorbing rod.

[0033] Specifically, the top of the drive shaft 16 drives the rotating shaft 21 to rotate through a bevel gear pair. The rotating shaft 21 drives the turntable 25 to rotate continuously through the bevel gear transmission. The connecting block 26, which is hinged to the outer circumference of the inner side of the turntable 25, moves eccentrically in a circular motion with the turntable 25. The eccentric trajectory drives the storage bin 20 to swing continuously in the filling box 7. With the shock-absorbing rod on the outer side of the storage bin 20 limiting and buffering, the storage bin 20 forms a small-amplitude, high-frequency reciprocating vibration. The continuous vibration breaks up the accumulation and clumping of lubricating powder, so that the lubricating powder inside the storage bin 20 falls evenly and continuously. It is sent into the discharge port 15 through the bottom discharge port and the connecting telescopic hose, avoiding the problem of dry powder retention and blockage. The storage bin 20 is connected to the inner box 17 through the telescopic hose to avoid motion interference.

[0034] Please see the appendix Figure 11 -Appendix Figure 13A switch frame 29 is slidably connected to the bottom of the filling box 7. A discharge port 15 is fixedly connected to the inner wall of the switch frame 29. The top input end of the discharge port 15 is connected to the discharge port of the storage bin 20 through a telescopic hose. A reciprocating push assembly is provided on the outer wall of the switch frame 29. The reciprocating push assembly includes a cam shaft 28 rotatably connected to the bottom inner wall of the filling box 7. A cam disk 32 is fixedly connected to the bottom of the cam shaft 28. The outer wall of the cam disk 32 abuts against the front outer wall of the switch frame 29. A telescopic rod 33 abuts against the rear outer wall of the switch frame 29. A movable block 31 driven by an electric push rod is installed on the front side of the top inner wall of the switch frame 29. A fixed block 30 is fixedly connected to the rear side of the top inner wall of the switch frame 29. The opening and closing of the discharge port 15 can be controlled by the horizontal movement of the movable block 31.

[0035] Specifically, the top of the transmission shaft 27 drives the camshaft 28 to rotate via gear transmission. The cam disk 32 at the bottom of the camshaft 28 rotates with it. During the rotation of the cam disk 32, its protruding outer edge continuously presses against the front outer wall of the switch frame 29. With the elastic reset effect of the rear telescopic rod 33, the switch frame 29 is driven to slide back and forth horizontally along the bottom of the filling box 7. The discharge port 15, which is fixed to the inner wall of the switch frame 29, moves synchronously with the switch frame 29 and swings back and forth above the powder box 5, evenly sprinkling the falling lubricating powder into the powder box 5. At the same time, the movable block 31, which is driven by an electric push rod at the top of the switch frame 29, moves horizontally through the electric push rod, changing the clamping distance between the movable block 31 and the fixed block 30. This can clamp or loosen the telescopic hose connecting the storage chamber 20 and the discharge port 15, realizing on-demand start and stop of powder supply and precise control of the discharge amount.

[0036] Please see the appendix Figure 14 and attached Figure 15 The outer wall of the dust collection chamber 8 is fixedly connected to the bottom of the support frame 1. The inner wall of the dust collection chamber 8 is equipped with a dust collection assembly for collecting lubricating dust generated during the pulling operation. The dust collection assembly includes a front panel 9 fixedly connected to the front side of the dust collection chamber 8. Multiple negative pressure fans are installed on the inner wall of the front panel 9 through a fixed bracket. A filter plate 36 is fixedly connected to the rear side of the front panel 9. A reciprocating threaded rod 34 is rotatably connected to the inner wall of the rear side of the dust collection chamber 8. A brush 35 is threadedly connected to the outer wall of the reciprocating threaded rod 34 for scraping off the solid lubricating powder adhering to the surface of the filter plate 36. A collection box 10 for collecting solid lubricating powder is slidably connected to the bottom of the dust collection chamber 8.

[0037] Specifically, during the drawing process, the negative pressure fan installed on the front panel 9 is started. The lubricating dust that escapes during the drawing process is sucked in through the grille on the top of the dust collection chamber 8 under the action of the negative pressure airflow generated by the negative pressure fan. The dust-laden airflow passes through the filter plate 36, and the solid lubricating powder is intercepted and adsorbed on its surface by the filter plate 36. The drive shaft 11 drives the reciprocating threaded rod 34 to rotate through the synchronous belt and synchronous pulley. The reciprocating threaded rod 34 drives the brush 35 to move back and forth along its axis. A dustproof membrane is installed in the sliding groove between the brush 35 and the dust collection chamber 8 to prevent dust from entering the area where the reciprocating threaded rod 34 is located. The bristles of the brush 35 scrape off the solid lubricating powder adsorbed on the surface of the filter plate 36 during the reciprocating motion. The scraped lubricating powder falls into the collection box 10 along the bottom guide plate of the filter plate 36. The operator periodically removes the collection box 10 to recycle or centrally process the collected lubricating powder.

[0038] Please see the appendix Figure 3 The guide assembly is installed on the front side of each station on the top of the support frame 1 to guide the stainless steel wire and coat its surface with lubricating powder. The guide assembly includes a powder box 5 rotatably connected to the top of the front side of the support frame 1. A wire drawing die box 12 is fixedly connected to the front side of the powder box 5. A wire drawing die 13 is inserted into the inner wall of the wire drawing die box 12. The top of the wire drawing die 13 is fixedly connected to the wire drawing die box 12 by bolts. A guide wheel 14 is rotatably connected to the rear side of the powder box 5 to guide the stainless steel wire into the powder box 5.

[0039] Specifically, the stainless steel wire is guided into the powder box 5 via the guide wheel 14, where the lubricating powder in the powder box 5 makes full contact with the surface to complete the dry coating lubrication. After being coated and lubricated, the stainless steel wire enters the wire drawing die box 12 and passes through the detachable wire drawing die 13 for diameter reduction forming. The powder box 5 can rotate on the top of the support frame 1 and its position can be adjusted according to the actual drawing situation. At the same time, the top of the wire drawing die 13 is fixedly connected to the wire drawing die box 12 by bolts, and the wire drawing die 13 with the corresponding hole diameter can be quickly replaced according to the drawing requirements of stainless steel wires of different specifications.
