Description

Technical Field

[0001] The invention relates to the technical field of wire drawing devices, in particular to a wire drawing machine for steel wire production. Background Art

[0002] A wire drawing machine is a mechanical device specially used to draw thick steel wire into thin steel wire of the required diameter through a series of dies. A wire drawing machine usually includes a pay-off assembly, a drawing die set, a traction assembly and a take-up assembly. The pay-off assembly is used to pay out the thick steel wire from the pay-off roller, the drawing die set is used to draw and reduce the diameter of the thick steel wire, and the traction assembly is used to pull the thin steel wire so that the thin steel wire can be reeled onto the reel corresponding to the take-up assembly.

[0003] The existing traction device is usually composed of a tension wheel and a wire wheel. The axis of the wire wheel is parallel to the axis of the winding roller, and the wire wheel can slide elastically along its axis. During the winding process, the wire wheel slides elastically along its axis under the pressure of the steel wire to automatically adjust the position of the wire wheel, so that the wire released by the wire wheel and the axis of the winding roller are perpendicular to each other as much as possible, so that the surface of the steel wire after winding is flat. However, the existing wire drawing machine traction assembly has the following problems when in use: when the elastic sliding distance of the wire wheel along its axis is large, the straight-line distance between the wire outlet point of the wire drawing module and the winding point of the winding roller is large. At this time, the tension on the steel wire increases, and the winding tightness of the steel wire wound on the winding roller increases; when the elastic sliding distance of the wire wheel along its axis is small, the straight-line distance between the wire outlet point of the wire drawing module and the winding point of the winding roller is small. At this time, the tension on the steel wire decreases, and the winding tightness of the steel wire wound on the winding roller decreases, which will cause the winding tightness of the steel wire wound on the winding roller to be different at different locations, that is, the internal stress distribution of the steel wire wound on the winding roller is uneven. This uneven stress distribution may cause the steel wire to deform, break, and other problems during subsequent processing or use. Summary of the invention

[0021] like Figures 1 to 10As shown, a wire drawing machine for steel wire production includes a machine platform 100, a wire-paying roller 200, a wire-drawing module 300 and a traction mechanism 400. The wire-paying roller 200 is rotatably arranged on the machine platform 100, and the wire-paying roller 200 is used to pay out the steel wire 1000. The wire-drawing module 300 is arranged on the machine platform 100, and the wire-drawing module 300 is used to draw the steel wire 1000 released by the wire-paying roller 200. The traction mechanism 400 includes a mobile driving component 410, a variable diameter driving component 420 and a support rod 430. The mobile driving component 410 is slidably arranged on the machine platform 100, and the mobile driving component 410 can move along Move in the first direction, there are multiple support rods 430, and the multiple support rods 430 are circumferentially evenly spaced around the first axis to form an annular contour, and the steel wire 1000 extending from the wire drawing die set 300 is wound around the outside of the annular contour. The variable diameter drive component 420 is connected to the mobile drive component 410, and the variable diameter drive component 420 cooperates with the support rods 430. The variable diameter drive component 420 is used to drive the multiple support rods 430 to synchronously approach or move away from the first axis to change the diameter of the annular contour. The wire take-up roller 500 is rotatably set on the machine table 100, and is used to wind up the steel wire 1000 wound from the annular contour.

[0022] When in use, the staff first installs the steel wire 1000 to be drawn on the pay-off roller 200, then passes one end of the steel wire 1000 through the wire drawing module 300, and winds the end passing through the wire drawing module 300 around the outside of the annular profile, and finally connects the steel wire 1000 wound from the annular profile to the take-up roller 500, then starts the pay-off roller 200, the traction mechanism 400 and the take-up roller 500, and the steel wire moves from the pay-off roller 200 to the take-up roller 500 in a directional manner, and passes through the wire drawing module 300 during the directional movement, so that the steel wire is in the wire drawing module. 300 is squeezed and drawn and wound onto the take-up roller 500. In the process of the steel wire 1000 being wound by the take-up roller 500, the moving drive assembly 410 drives the variable diameter drive assembly 420 to move synchronously along the first direction. The variable diameter drive assembly 420 drives the annular profile surrounded by the plurality of support rods 430 to move synchronously along the first direction, so that the steel wire 1000 wound out of the annular profile is kept perpendicular to the axis of the take-up roller 500, so that the surface of the steel wire 1000 wound onto the take-up roller 500 is kept flat. During the synchronous movement of the mobile driving assembly 410, the straight-line distance between the winding point of the steel wire 1000 of the annular contour surrounded by the multiple support rods 430 and the wire drawing module 300 increases and decreases reciprocatingly within a preset range. When the straight-line distance between the winding point of the steel wire 1000 of the annular contour surrounded by the multiple support rods 430 and the wire drawing module 300 begins to gradually increase, the variable diameter driving assembly 420 drives the multiple support rods 430 to synchronously approach the first axis to reduce the diameter of the annular contour to prevent the tension of the steel wire 1000 wound on the annular contour from being too large. Conversely, when When the straight-line distance between the winding entry point of the steel wire of the annular contour surrounded by multiple support rods 430 and the wire drawing module 300 begins to gradually decrease, the variable diameter drive assembly 420 drives the multiple support rods 430 to synchronously move away from the first axis to increase the diameter of the annular contour, thereby preventing the tension of the steel wire 1000 wound on the annular contour steel wire 1000 from being too small, thereby ensuring that the internal stress distribution of the steel wire 1000 wound onto the take-up roller 500 is uniform, and avoiding deformation or breakage of the steel wire 1000 due to uneven internal stress distribution during subsequent processing or use.

[0023] In this embodiment, the mobile drive assembly 410 includes a first screw 411, a first sliding plate 412 and a guide plate 413. The first screw 411 is rotatably set on the machine 100, and the axis of the first screw 411 coincides with the straight line corresponding to the first direction. There are two guide plates 413, and the two guide plates 413 are set on the machine 100 and are respectively located on both sides of the first screw 411. The middle part of the first sliding plate 412 is threadedly connected to the first screw 411, and the two sides of the first sliding plate 412 are slidably connected to the guide plates 413. The upper part of the first sliding plate 412 is connected to the variable diameter drive assembly 420.

[0024] When in use, the staff rotates the first screw 411 around its axis. Under the limiting action of the two first guide plates 413, the rotation of the first screw 411 drives the first sliding plate 412 to move along the axis of the first screw 411, that is, to move along the first direction. Since the variable diameter drive assembly 420 is connected to the first sliding plate 412, the first sliding plate 412 drives the variable diameter drive assembly 420 to move synchronously along the first direction, so that the steel wire 1000 wound out from the annular contour remains perpendicular to the axis of the take-up roller 500.

[0025] In this embodiment, a second driving source 414 is disposed on the machine 100 , and an output end of the second driving source 414 is coaxially fixedly connected to the first screw rod 411 .

[0026] To drive the first screw rod 411 to rotate, the second driving source 414 is started. The second driving source 414 is specifically a servo motor. The output shaft of the servo motor drives the first screw rod 411 to rotate synchronously to drive the first sliding plate 412 to slide back and forth along the first direction.

[0027] In this embodiment, a third driving source 510 is further provided on the machine 100 , the output end of the third driving source 510 is coaxially connected to the take-up roller 500 , and the control module of the third driving source 510 is electrically connected to the control module of the second driving source 414 .

[0028] To drive the take-up roller 500 to rotate, the third driving source 510 is started. Specifically, the third driving source 510 is also a servo motor. The output shaft of the servo motor drives the take-up roller 500 to rotate, so that the steel wire 1000 is gradually wound onto the take-up roller 500.

[0029] It should also be added that in order to keep the steel wire 1000 wound out from the annular contour perpendicular to the axis of the take-up roller 500, the control module of the third drive source 510 should be electrically connected to the control module of the second drive source 414 so that the take-up roller 500 and the first sliding plate 412 remain synchronized. Specifically, the feed speed of the first sliding plate 412 should be adjusted so that the distance moved by the first sliding plate 412 within the time period corresponding to one rotation cycle of the take-up roller 500 is equal to the diameter of the steel wire 1000.

[0030] In this embodiment, the variable diameter driving assembly 420 includes a first fixed ring 421, a second fixed ring 422, an intermediate connecting rod 423 and a rotating gear ring 424. The first fixed ring 421 is fixedly arranged on the upper surface of the first sliding plate 412. The upper end surface of the first fixed ring 421 is provided with a plurality of first linear slide grooves 4211. The first linear slide grooves 4211 extend along the radial direction of the first fixed ring 421. The plurality of first linear slide grooves 4211 correspond to the plurality of support rods 430 one by one and slideably cooperate. The intermediate connecting rod 423 is coaxially fixedly connected to the first fixed ring 421. The second fixed ring 422 is coaxially arranged at one end of the intermediate connecting rod 423 away from the first fixed ring 421. The lower end surface of the second fixed ring 422 is provided with a plurality of first linear slide grooves 4211. There are multiple second linear slide grooves 4221, which extend radially along the second fixed ring 422. The multiple second linear slide grooves 4221 correspond one-to-one to the multiple support rods 430 and slide with one end of the multiple support rods 430 away from the first linear slide groove 4211. The rotating gear ring 424 is coaxially rotatably arranged on the outside of the intermediate connecting rod 423, and the rotating gear ring 424 is located between the first fixed ring 421 and the second fixed ring 422. The upper surface of the rotating gear ring 424 is provided with multiple third linear slide grooves 4241, which extend in a direction inclined to the radial direction of the rotating gear ring 424. The multiple third linear slide grooves 4241 correspond one-to-one to the multiple support rods 430 and slide with each other.

[0031] When it is necessary to reduce the diameter of the annular contour, the staff rotates the rotating gear ring 424 clockwise around its axis. Under the joint guidance of the first linear slide groove 4211 and the third linear slide groove 4241, the multiple support rods 430 synchronously approach the first axis, so that the diameter of the annular contour surrounded by the multiple support rods 430 is reduced.

[0032] When it is necessary to increase the diameter of the annular contour, the staff rotates the rotating gear ring 424 counterclockwise around its axis. Under the joint guidance of the first linear slide groove 4211 and the third linear slide groove 4241, the multiple support rods 430 synchronously move away from the first axis, so that the diameter of the annular contour surrounded by the multiple support rods 430 increases.

[0033] In this embodiment, a first driving source 425 is further disposed on the upper surface of the first sliding plate 412 . A first gear 426 is coaxially disposed at the output end of the first driving source 425 . The first gear 426 is meshed with the rotating gear ring 424 .

[0034] When the rotating gear ring 424 needs to be rotated, the staff starts the first driving source 425, specifically, the first driving source 425 is a servo motor, at which time the output shaft of the servo motor drives the first gear 426 to rotate, and the first gear 426 drives the rotating gear ring 424 to rotate through gear meshing.

[0035] It should be supplemented that a pressure sensor is provided on the outside of the support rod 430 and at the position corresponding to the position where the steel wire 1000 is wrapped around the support contour. The pressure sensor is electrically connected to the control module of the first driving source 425. When the pressure received by the pressure sensor is greater than a preset value, the first driving source 425 reduces the diameter of the annular contour. When the pressure received by the pressure sensor is less than the preset value, the first driving source 425 increases the diameter of the annular contour.

[0036] When the rotation speed of the pay-off roller 200 and the take-up roller 500 remains unchanged, when the straight-line distance between the annular contour surrounded by the multiple support rods 430 and the drawing module 300 increases, the length of the steel wire 1000 located between the outlet of the drawing module 300 and the winding point of the annular contour increases, and thus the pressure between the steel wire 1000 and the winding point of the annular contour increases. When the pressure received by the pressure sensor is greater than the preset value, the first driving source 425 causes the rotating gear ring 424 to rotate clockwise through the first gear 426. Under the joint guiding action of the first linear slide groove 4211 and the third linear slide groove 4241, the multiple support rods 430 synchronously approach the first axis, so that the diameter of the annular contour surrounded by the multiple support rods 430 is reduced, thereby reducing the length of the steel wire 1000 wound on the annular contour, thereby reducing the pressure between the steel wire 1000 and the winding point of the annular contour, and preventing the steel wire 1000 from being wound on the annular contour. The tension of the wire 1000 is too large. Conversely, when the straight-line distance between the annular contour surrounded by the multiple support rods 430 and the wire drawing module 300 decreases, the length of the steel wire 1000 located between the outlet of the wire drawing module 300 and the winding point of the annular contour decreases, so the pressure between the steel wire 1000 and the winding point of the annular contour decreases. When the pressure received by the pressure sensor is less than the preset value, the first driving source 425 causes the rotating gear ring 424 to rotate counterclockwise through the first gear 426. Under the joint guiding action of the first linear slide groove 4211 and the third linear slide groove 4241, the multiple support rods 430 synchronously move away from the first axis, so that the diameter of the annular contour surrounded by the multiple support rods 430 increases, thereby increasing the length of the steel wire 1000 wound on the annular contour, thereby increasing the pressure between the steel wire 1000 and the winding point of the annular contour, and preventing the tension of the steel wire 1000 wound on the annular contour from being too small.

[0037] In this embodiment, a plurality of spiral bevel grooves 431 are formed on one side of the surface of the support rod 430 , and the plurality of spiral bevel grooves 431 are arranged at equal intervals along the axis of the support rod 430 .

[0038] It can be understood that a plurality of spiral bevel grooves 431 are provided on one side of the surface of the support rod 430 and are arranged at equal intervals along the axis of the support rod 430 so as to allow the steel wires 1000 wound around the outside of the annular contour to be staggered in the axial direction of the annular contour, thereby preventing the steel wires 1000 wound around the annular contour from being interlaced with each other and being torn off.

[0039] It should also be noted that, since the lower portion of the support rod 430 is slidably fitted in the first linear groove 4211 and the third linear groove 4241, the lower portion of the support rod 430 does not need to have a spiral bevel groove 431, and the lower portion of the support rod 430 can be a bare rod.

[0040] In this embodiment, a plurality of oil filling holes 433 are provided on the other side of the surface of the support rod 430, and the plurality of oil filling holes 433 correspond one-to-one to the plurality of spiral bevel grooves 431. An oil chamber 432 is provided inside the support rod 430, and the oil chamber 432 extends along the axis of the support rod 430, and the oil chamber 432 is communicated with the plurality of oil filling holes 433. A filling assembly 440 is provided at the upper end of the support rod 430, and the filling assembly 440 is used to intermittently inject lubricating oil into the oil chamber 432.

[0041] Since there is a certain pressure between the steel wire 1000 and the support rod 430, the support rod 430 will be forced to rotate around its own axis during the process of the steel wire 1000 moving around the annular contour thread. Since the filling assembly 440 intermittently injects lubricating oil into the oil chamber 432, and the oil chamber 432 is connected to the oil filling hole 433, the lubricating oil in the oil chamber 432 will be squeezed outward from the oil filling hole 433 and adhere to the side surface of the support rod 430 where the oil filling hole 433 is opened. When the support rod 430 rotates to the side where the oil filling hole 433 is opened and contacts with the steel wire 1000, the lubricating oil adheres to the surface of the steel wire 1000, which is used to absorb heat and cool the steel wire 1000, so as to prevent the steel wire 1000 from being wound onto the take-up roller 500 from having too high a temperature and causing excessive stress changes.

[0042] It should also be noted that when the support rod 430 rotates until the spiral groove 431 contacts the steel wire 1000 again, part of the lubricating oil on the steel wire 1000 will be transferred to the spiral groove 431 to lubricate the spiral groove 431 and prevent excessive wear of the spiral groove 431. In addition, it can also reduce the lubricating oil on the surface of the steel wire 1000 and prevent the surface of the steel wire 1000 wound on the take-up roller 500 from being adsorbed with excessive dust and other particulate matter.

[0043] In this embodiment, the filling assembly 440 includes a sliding end cover 441, an oil pipe 442 and an oil tank 443. The sliding end cover 441 is coaxially sleeved with the upper end of the support rod 430. Specifically, the support rod 430 and the sliding end cover 441 can move relative to each other along the axis of the support rod 430 and rotate relative to each other around the axis of the support rod 430. A chamber for accommodating lubricating oil is formed between the support rod 430 and the sliding end cover 441. A first elastic member 444 is provided between the sliding end cover 441 and the support rod 430. The first elastic member 444 is specifically a tension spring. The first elastic member 444 is used to make the sliding end cover 441 and the support rod 430 move relative to each other along the axis of the sliding end cover 4 41 are away from each other in axial directions, the sliding end cover 441 is slidably connected to the upper surface of the second fixed ring 422, and the diameter of the sliding end cover 441 is larger than the width of the second linear slide groove 4221, one end of the oil pipe 442 is inserted into the sliding end cover 441, and a one-way valve 445 is provided at the connection between the oil pipe 442 and the sliding end cover 441, and the one-way valve 445 limits the lubricating oil in the oil chamber 432 from flowing back into the oil pipe 442, and the oil tank 443 is provided on the second fixed ring 422, and the lubricating oil is stored in the oil tank 443, and the height of the oil tank 443 is higher than the height of the oil chamber 432, and the oil tank 443 is connected to one end of the oil pipe 442 away from the sliding end cover 441.

[0044] Since the steel wire 1000 is wound from the upper part of the annular profile into the lower part and wound out, during the spiral movement of the steel wire 1000, the steel wire 1000 will apply a force downward along the axis of the support rod 430 through the spiral bevel 431 on the support rod 430. This force overcomes the elastic force of the first elastic member 444 to make the support rod 430 move downward along its axis. At this time, the volume of the chamber in which the first elastic member 444 and the support rod 430 slide together increases, so that the pressure in the chamber is reduced. Under the pressure difference, the one-way valve 445 is pushed open downward, and the lubricating oil in the oil pipe 442 is replenished into the chamber. When the support rod 430 is in a state of being pressed downward, the lubricating oil in the oil pipe 442 is replenished into the chamber. When the rod 430 rotates until the steel wire 1000 no longer contacts the side of the non-spiral groove 431 of the support rod 430, the downward force applied by the steel wire 1000 to the support rod 430 along its axis is significantly reduced. Under the action of the first elastic member 444, the support rod 430 moves upward, and the volume of the chamber formed between the first elastic member 444 and the support rod 430 decreases, and the pressure in the chamber increases. The one-way valve 445 is then pressed to move upward to seal the oil pipe 442 in one direction. Therefore, the lubricating oil can only be discharged outward through the oil filling hole 433, so that the lubricating oil adheres to the side surface of the support rod 430 where the oil filling hole 433 is opened. It should also be added that, in order to control the amount of lubricating oil discharged out of the oil filling hole 433 at a time, it is necessary to limit the moving distance of the support rod 430. Specifically, the diameter of the lower rod portion of the support rod 430 is slightly smaller than the diameter of the portion where the spiral groove 431 is located. In this way, when the support rod 430 moves downward until the lower end face of the portion where the spiral groove 431 is located abuts against the upper end face of the rotating gear ring 424, the support rod 430 cannot continue to move downward, and the volume of the chamber between the support rod 430 and the sliding end cover 441 cannot continue to increase. Therefore, the pressure difference between the inside and outside of the chamber will not continue to increase, and the lubricating oil will not continue to be pressurized and discharged out through the oil filling hole 433.
