Description
Technical Field
[0001] This application relates to the field of steel wire processing equipment, and in particular to a straightening device for a stranding machine. Background Technology
[0002] A stranding machine is a machine that twists several metal wires into strands according to a certain twist pitch and twist direction. It is also a device that arranges multiple steel wires regularly and twists them evenly into steel wire rope products. It is also known as a stranding rope unit and is widely used in oil drilling, power transmission, ship lifting and loading, elevator lifting and other fields.
[0003] In the process of using a stranding machine, purchased coiled wire rope rollers are installed inside the machine. The wires unwound from multiple rollers are twisted into strands to form wire rope products. However, the wires wound on the rollers themselves have a certain bending stress during the production process. The initial bending stress of the wires on the rollers at different positions on the stranding machine may vary greatly depending on the production batch. Directly installing the purchased rollers onto the stranding machine for production can easily lead to significant quality problems and defects in the produced wire ropes. Utility Model Content
[0004] To address the issue of significant differences in bending stress among steel wires on different rollers of a twisting machine, this application provides a straightening device for a twisting machine.
[0005] The straightening device for a twisting machine provided in this application adopts the following technical solution: A straightening device for a strand twisting machine includes a wire feeding frame, a straightening platform, and a winding frame arranged sequentially. A wire feeding roller is rotatably mounted on the wire feeding frame, and a wire winding roller is rotatably mounted on the winding frame. A winding member for driving the winding roller to rotate is mounted on the winding frame. A straightening assembly and a straightening assembly are mounted on the straightening platform. The straightening assembly is used to straighten the steel wire unwound from the wire feeding roller, and the straightening assembly is used to straighten the straightened steel wire. The straightening assembly includes multiple mounting plates mounted on the straightening platform, arranged along the direction from the wire feeding frame to the winding frame. A tensioning plate is slidably mounted on the mounting plate, and a sliding groove is provided on the mounting plate for the tensioning plate to slide. Multiple positioning wheels are rotatably mounted on the mounting plate, and the multiple positioning wheels are evenly arranged along the direction from the wire feeding frame to the winding frame. Multiple dynamic pressure wheels are rotatably mounted on the tensioning plate, and the multiple dynamic pressure wheels are evenly arranged along the direction from the wire feeding frame to the winding frame. The positioning wheels and the dynamic pressure wheels are arranged alternately. The mounting plate is provided with positioning components for fixing the tensioning plate, and the tensioning plate is provided with adjusting components for adjusting the distance between the positioning wheels and the dynamic pressure wheels.
[0006] By adopting the above technical solution, workers first install the purchased wire feeding rollers on the wire feeding frame. Then, the steel wire unwound from the wire feeding rollers passes through the gap between the positioning rollers and the dynamic pressure rollers before being wound onto the take-up rollers. Afterward, workers adjust the distance between the positioning rollers and the dynamic pressure rollers using the adjusting device, thus compressing the steel wire. Through multiple positioning rollers and dynamic pressure rollers, the steel wire is straightened during the conveying process, eliminating most of the bending stress. Subsequently, the straightening assembly straightens the straightened steel wire. Finally, the take-up roller winds up the straightened steel wire. The resulting steel wire has a more uniform bending stress, thereby improving the quality of the steel wire rope produced subsequently.
[0007] Optionally, the mounting plate is arranged at an angle on the straightening platform, and the angles of inclination of two adjacent mounting plates are different.
[0008] By adopting the above technical solution, the steel wire can be corrected at multiple angles, which helps to eliminate the bending stress on the steel wire.
[0009] Optionally, the positioning element includes a mounting ear plate disposed on the straightening platform, and a positioning bolt is threadedly connected to the mounting ear plate. The positioning bolt is used to press the tensioning plate onto the mounting plate.
[0010] By adopting the above technical solution, workers tighten the positioning bolts, which press the tensioning plate onto the mounting plate. This structure is simple and easy to operate, greatly reducing the difficulty of operation for workers.
[0011] Optionally, the adjusting component includes multiple adjusting blocks slidably disposed on the tensioning plate, each adjusting block corresponding to one of the dynamic pressure rollers, the dynamic pressure rollers being rotatably disposed on the adjusting blocks, the tensioning plate having adjusting grooves for the adjusting blocks to slide, and multiple adjusting bolts threadedly connected to the side of the tensioning plate facing away from the mounting plate, each adjusting bolt corresponding to one of the adjusting blocks, the adjusting blocks being rotatably disposed on the adjusting bolts.
[0012] By adopting the above technical solution, workers can tighten different adjusting bolts to make the distance between the positioning wheel and the dynamic pressure wheel at different positions different, thereby achieving the effect of gradually tightening the steel wire, reducing the possibility of sudden tension change caused by the sudden tightening of the steel wire, and helping to reduce the possibility of steel wire damage.
[0013] Optionally, the straightening assembly includes a first ferry and a second ferry rotatably mounted on the straightening platform. The diameter of the first ferry is larger than that of the second ferry. The steel wire passing through the mounting plate is wound multiple times between the first ferry and the second ferry before being wound onto the take-up roller. A straightening motor electrically connected to the control system is provided on the straightening platform, and the second ferry is coaxially mounted on the output shaft of the straightening motor.
[0014] By adopting the above technical solution, the control system starts the straightening motor, the output shaft of the straightening motor drives the second ferry to rotate, and the rotating second ferry drives the steel wire to rotate through friction. Under the action of the first ferry, the steel wire will be straightened during the conveying process, thereby solving the problem of the steel wire bending and deformation during the straightening process, which leads to the deterioration of the surface quality of the steel wire.
[0015] Optionally, the straightening platform is equipped with an encoder electrically connected to the control system, and the rotating shaft of the encoder is coaxially mounted on the second ferry.
[0016] By adopting the above technical solution, the encoder indirectly records the length of the wire wound on the take-up roller by recording the number of rotations of the second ferry.
[0017] Optionally, the take-up component includes a take-up motor disposed on the take-up frame and electrically connected to the control system, and a coupling is provided between the take-up roller and the output shaft of the take-up motor.
[0018] By adopting the above technical solution, the control system starts the winding motor, and the output shaft of the winding motor drives the winding roller to rotate and wind up the straightened steel wire through the coupling.
[0019] Optionally, the take-up frame is provided with two wire-binding posts, and the steel wire passes through the two wire-binding posts. A wire-shifting block is slidably arranged between the wire-binding posts and the take-up roller. A wire-binding ring is provided on the wire-shifting block, and the steel wire passes through the ring of the wire-binding ring. The take-up frame is provided with a guide post, and the wire-shifting block is slidably sleeved on the guide post. A screw is rotatably arranged on the take-up frame, and the length direction of the screw is parallel to the axial direction of the guide post. The wire-shifting block is threadedly connected to the screw. A wire-shifting motor electrically connected to the control system is provided on the take-up frame, and the screw is coaxially arranged on the output shaft of the wire-shifting motor.
[0020] By adopting the above technical solution, during the process of the take-up roller winding the steel wire, the control system starts the shifting block motor. The output shaft of the shifting block motor drives the screw to rotate. Under the restriction of the guide post, the shifting block drives the wire bundle ring to slide along the axial direction of the guide post. During this process, the wire bundle ring makes the steel wire evenly wound on the take-up roller, thereby improving the uniformity of the bending stress on the steel wire wound on the take-up roller, which is beneficial to improving the quality of the subsequent stranded steel wire rope.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The worker first installs the purchased wire feeding roller on the wire feeding frame. Then, the wire unwound from the wire feeding roller passes through the gap between the positioning roller and the dynamic pressure roller and is wound onto the take-up roller. After that, the worker changes the distance between the positioning roller and the dynamic pressure roller using the adjusting device to compress the wire. Through multiple positioning rollers and dynamic pressure rollers, the wire is straightened during the conveying process, eliminating most of the bending stress. Subsequently, the straightening assembly straightens the straightened wire. Finally, the take-up roller takes up the straightened wire. The bending stress on the wire obtained in this way tends to be the same, thereby improving the quality of the wire rope produced in the subsequent production. 2. By tightening different adjusting bolts, the distance between the positioning wheel and the dynamic pressure wheel at different positions can be made different, thereby achieving the effect of gradually tightening the steel wire. This reduces the possibility of sudden tension changes caused by the sudden tightening of the steel wire, which helps to reduce the possibility of damage to the steel wire. 3. During the winding process of the take-up roller, the control system starts the shifting block motor. The output shaft of the shifting block motor drives the screw to rotate. Under the constraint of the guide post, the shifting block drives the wire bundle ring to slide along the axial direction of the guide post. During this process, the wire bundle ring makes the wire evenly wound on the take-up roller, thereby improving the uniformity of the bending stress on the wire wound on the take-up roller, which is beneficial to improving the quality of the subsequent stranded wire rope.

[0026] The following is in conjunction with the appendix Figures 1-3This application will be described in further detail.
[0027] This application discloses a straightening device for a twisting machine.
[0028] Reference Figure 1 A straightening device for a twisting machine includes a pay-off frame 1, a straightening platform 2, and a take-up frame 3 arranged in sequence. A pay-off shaft 16 is rotatably connected to the pay-off frame 1, and a pay-off roller 4 is coaxially bolted to the pay-off shaft 16. A take-up shaft 17 is rotatably connected to the take-up frame 3, and a take-up roller 5 is coaxially bolted to the take-up shaft 17. A take-up component 6 for driving the take-up roller 5 to rotate is arranged on the take-up frame 3.
[0029] Reference Figure 1 and Figure 2 The take-up component 6 includes a take-up motor 61 bolted to the take-up frame 3 and electrically connected to the control system. A coupling 62 is bolted between the take-up shaft 17 and the output shaft of the take-up motor 61. Two wire-binding posts 10 are bolted to the take-up frame 3. The steel wire passes between the two wire-binding posts 10. A wire-shifting block 11 is slidably arranged between the wire-binding post 10 and the take-up roller 5. A wire-binding ring 12 is welded onto the wire-shifting block 11.
[0030] Reference Figure 1 and Figure 2 The steel wire passes through the loop of the wire harness 12. A guide post 13 is welded on the winding frame 3. The wire transfer block 11 is slidably sleeved on the guide post 13. A screw 14 is rotatably connected to the winding frame 3. The length direction of the screw 14 is parallel to the axis of the guide post 13. The wire transfer block 11 is threadedly connected to the screw 14. A transfer block motor 15, which is electrically connected to the control system, is bolted to the winding frame 3. The screw 14 is coaxially bolted to the output shaft of the transfer block motor 15.
[0031] The worker first installs the purchased pay-off roller 4 onto the pay-off shaft 16 on the pay-off frame 1. Then, the steel wire unwound from the pay-off roller 4 is wound onto the take-up roller 5 via the wire-binding post 10 and the wire-binding ring 12. The control system starts the take-up motor 61. The output shaft of the take-up motor 61 drives the take-up roller 5 to rotate and take up the steel wire through the coupling 62. During this process, the control system starts the shift block motor 15. The output shaft of the shift block motor 15 drives the screw 14 to rotate. Under the restriction of the guide post 13, the shift block 11 drives the wire-binding ring 12 to slide along the axial direction of the guide post 13. During this process, the wire-binding ring 12 makes the steel wire evenly wound on the take-up roller 5.
[0032] Reference Figure 1 and Figure 3A straightening assembly 7 is arranged on the straightening platform 2. The straightening assembly 7 is used to straighten the steel wire unwound on the unwound roller 4. The straightening assembly 7 includes multiple mounting plates 71 bolted to the straightening platform 2. The multiple mounting plates 71 are arranged along the direction from the unwound frame 1 to the winding frame 3. The mounting plates 71 are arranged at an angle on the straightening platform 2, and the inclination angles of two adjacent mounting plates 71 are different.
[0033] Reference Figure 1 and Figure 3 A tensioning plate 72 is slidably arranged on the mounting plate 71. A sliding groove 73 is provided on the mounting plate 71 for the tensioning plate 72 to slide. Multiple positioning wheels 74 are rotatably connected to the mounting plate 71. The multiple positioning wheels 74 are evenly arranged along the direction from the wire feeding frame 1 to the winding frame 3. Multiple dynamic pressure wheels 75 are rotatably arranged on the tensioning plate 72. The multiple dynamic pressure wheels 75 are evenly arranged along the direction from the wire feeding frame 1 to the winding frame 3. The positioning wheels 74 and the dynamic pressure wheels 75 are arranged alternately.
[0034] Reference Figure 3 The mounting plate 71 is provided with a positioning element 76 for fixing the tension plate 72. The positioning element 76 includes a mounting ear plate 761 bolted to the straightening platform 2. The mounting ear plate 761 is threaded with a positioning bolt 762, which is used to press the tension plate 72 onto the mounting plate 71.
[0035] Reference Figure 3 The tensioning plate 72 is provided with an adjusting element 77 for adjusting the distance between the positioning wheel 74 and the dynamic pressure wheel 75.
[0036] Reference Figure 3 The adjusting component 77 includes multiple adjusting blocks 771 slidably arranged on the tensioning plate 72. Each adjusting block 771 corresponds to a dynamic pressure roller 75. The dynamic pressure roller 75 is rotatably connected to the adjusting block 771. The tensioning plate 72 is provided with adjusting grooves 772 for the adjusting blocks 771 to slide. Multiple adjusting bolts 773 are threadedly connected to the side of the tensioning plate 72 facing away from the mounting plate 71. Each adjusting bolt 773 corresponds to an adjusting block 771. The adjusting block 771 is rotatably connected to the adjusting bolt 773.
[0037] Before winding the steel wire, the worker tightens the adjusting bolt 773. The adjusting bolt 773 rotates and pushes the adjusting block 771 to slide. The adjusting block 771 drives the dynamic pressure roller 75 to press the steel wire tightly onto the positioning roller 74. By adjusting the distance between the positioning roller 74 and the dynamic pressure roller 75 at different positions, the steel wire undergoes different degrees of deformation. As the steel wire is continuously conveyed, the squeezing force between the positioning roller 74 and the dynamic pressure roller 75 will gradually eliminate the bending stress on the steel wire.
[0038] Reference Figure 1A straightening assembly 8 is arranged on the straightening platform 2. The straightening assembly 8 is used to straighten the straightened steel wire. The straightening assembly 8 includes a first ferry 81 and a second ferry 82 rotatably connected to the straightening platform 2. The steel wire passing through the mounting plate 71 is wound around the first ferry 81 and the second ferry 82 multiple times and then wound onto the take-up roller 5.
[0039] Reference Figure 1 The diameter of the first ferry 81 is larger than that of the second ferry 82. A straightening motor 83, which is electrically connected to the control system, is bolted to the straightening platform 2. The second ferry 82 is coaxially bolted to the output shaft of the straightening motor 83. An encoder 9, which is electrically connected to the control system, is bolted to the straightening platform 2. The rotating shaft of the encoder 9 is coaxially bolted to the second ferry 82.
[0040] As the steel wire, whose bending stress has been eliminated, passes over the first ferry 81 and the second ferry 82, the rotating second ferry 82 drives the steel wire to rotate through friction. Under the constraint of the first ferry 81, the steel wire is straightened during the transport process, thus solving the problem of bending deformation of the steel wire during the straightening process.
[0041] The implementation principle of a straightening device for a twisting machine according to an embodiment of this application is as follows: the worker first installs the purchased wire feeding roller 4 on the wire feeding shaft 16 on the wire feeding frame 1, then winds the wire unwound from the wire feeding roller 4 onto the first ferry 81 and the second ferry 82, and then winds it onto the take-up roller 5 through the wire binding post 10 and the wire binding ring 12.
[0042] The worker tightens the adjusting bolt 773, which rotates and pushes the adjusting block 771 to slide. The adjusting block 771 drives the dynamic pressure roller 75 to press the steel wire onto the positioning roller 74. By adjusting the distance between the positioning roller 74 and the dynamic pressure roller 75 at different positions, the steel wire undergoes different degrees of deformation.
[0043] The control system starts the winding motor 61. The output shaft of the winding motor 61 drives the take-up roller 5 to rotate and wind up the steel wire through the coupling 62. During this process, as the steel wire is continuously fed, the squeezing force between the positioning wheel 74 and the dynamic pressure wheel 75 will gradually eliminate the bending stress on the steel wire.
[0044] As the steel wire, whose bending stress has been eliminated, passes over the first ferry 81 and the second ferry 82, the rotating second ferry 82 drives the steel wire to rotate through friction. Under the constraint of the first ferry 81, the steel wire is straightened during the transport process, thus solving the problem of bending deformation of the steel wire during the straightening process.
[0045] At the same time, the control system starts the shifting block motor 15. The output shaft of the shifting block motor 15 drives the screw 14 to rotate. Under the restriction of the guide post 13, the shifting block 11 drives the wire bundle ring 12 to slide along the axial direction of the guide post 13. During this process, the wire bundle ring 12 makes the steel wire evenly wound on the take-up roller 5.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
