Description

Technical Field

[0001] The invention relates to the technical field of wire rope cutting and processing, and in particular to a device and method for automatically cutting wire rope to a certain length. Background Art

[0002] In many fields of modern industrial production, such as construction, lifting and transportation, mining and bridge construction, wire ropes are widely used as an indispensable component in various load-bearing, traction and lifting operations. Since different application scenarios have specific and strict requirements on the length of wire ropes, the cutting of wire ropes has become a key link in the production and use process.

[0003] As an important load-bearing component, wire rope is widely used in port machinery, mining equipment, bridge construction, elevator cables, etc. With the improvement of industrial automation level, higher requirements are put forward for the accuracy, efficiency and safety of wire rope cutting.

[0004] For example, a Chinese patent with announcement number CN111229994B discloses an automatic wire rope cutting device, in which a feeding mechanism includes at least one feeding plate for feeding the wire rope and a guide wheel for pulling the wire rope, a first clamping mechanism is movably arranged between the guide wheel of the feeding mechanism and the cutting mechanism, a material receiving walking mechanism is movably arranged on the side away from the cutting mechanism, and is connected to the second clamping mechanism, so that the second clamping mechanism and the material receiving walking mechanism constitute a tensioning moving component that can move the wire rope, and the cutting cylinder of the cutting mechanism is connected to the cutting table in the vertical direction of the wire rope travel, and the cutter is perpendicular to the travel direction of the wire rope on the frame, and the cutting cylinder is started, and the cutter can quickly cut the wire rope passing through the cutting table. The above existing documents can realize the rapid cutting of multiple wire ropes at the same time, solving the problem of low efficiency of wire rope cutting in the prior art; However, the above device still has some shortcomings in actual use: The above-mentioned device can be connected with the second clamping mechanism by arranging a material receiving walking mechanism, so that the second clamping mechanism and the material receiving walking mechanism constitute a tensioning moving component that can move the wire rope. However, the material receiving walking mechanism needs to return to the initial position after walking to a certain position, continue to clamp the next section of the wire rope, and pull the wire rope again to walk. This will cause the wire rope to be unable to always walk under the clamping of the material receiving walking mechanism during the reciprocating process. There is a time difference between clamping and pulling at different times, and continuous and uninterrupted cutting cannot be achieved, thereby reducing the actual production efficiency in the large-scale wire rope production process.

[0005] Therefore, under the viewpoints stated above, it is of great significance to improve and perfect the automatic cutting device for wire ropes, which can reduce the time difference between the movement and cutting of wire ropes and ensure the cutting efficiency of wire ropes. Summary of the Invention

[0006] To solve the above problems, the present invention provides an automatic fixed-length cutting device and method for wire ropes.

[0007] On the one hand, an automatic fixed-length cutting device for wire ropes includes a fixed frame. On the fixed frame, there is a U-shaped plate for guiding and positioning the wire rope. On one side of the opening of the U-shaped plate, a control plate is slidably arranged. Along the length direction of the U-shaped plate, a through groove penetrating up and down is opened, and a cutter groove is opened at the bottom of the U-shaped plate.

Detailed implementation manners

[0033] The following is combined with Figure 1-Figure 9 to describe the embodiments of the present invention in detail.

[0034] The embodiments of the present application disclose a steel wire rope automatic fixed-length cutting device and method. The present invention is mainly applied in the process of steel wire rope cutting. In terms of technical effects, it can avoid the time difference in pulling the steel wire rope and cannot achieve continuous and uninterrupted cutting. Therefore, in the process of mass production of steel wire ropes, the actual production efficiency is reduced.

[0035] Embodiment 1: Referring to Figure 1 As shown in the figure, it includes a fixing frame 1. The wire rope in a disc-shaped package is placed on the fixing frame 1. A U-shaped plate 10 for guiding and positioning the wire rope is arranged on the fixing frame 1. One end of the wire rope is guided into the interior of the U-shaped plate 10. A control plate 11 is slidably arranged on one side of the opening of the U-shaped plate 10. The function of the control plate 11 is to adjust the distance between the control plate 11 and the inner wall of the U-shaped plate 10 before the wire rope enters the U-shaped plate 10, and clamp the wire rope entering the interior of the U-shaped plate 10 through the control plate 11. It should be noted here that the clamping of the wire rope by the control plate 11 is not strong, only playing a guiding role, because the wire rope in the disc-shaped package has a certain degree of curvature, preventing the wire rope in the U-shaped plate 10 from bending and affecting subsequent clamping and cutting.

[0036] Refer to Figure 1 As shown in the figure, it is a schematic structural diagram for conveying the wire rope; specifically, one end of the U-shaped plate 10 is provided with a first guide roller 60 and a second guide roller 61 that are rotatably arranged on the fixing frame 1. The first guide roller 60 and the second guide roller 61 rotate synchronously through gears. Before the work starts, the operator guides one end of the wire rope in the disc-shaped package between the first guide roller 60 and the second guide roller 61, and uses the extrusion force generated by the relative rotation of the first guide roller 60 and the second guide roller 61 to send the wire rope into the interior of the U-shaped plate 10.

[0037] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in the figure, it is a schematic structural diagram for cutting the wire rope; specifically, a through groove 12 that penetrates up and down is formed along the length direction of the U-shaped plate 10, and a cutter groove 13 is formed at the bottom of the U-shaped plate 10. A cutting structure 14 that cooperates with the cutter groove 13 is arranged on the fixing frame 1. The wire rope entering the U-shaped plate 10 is cut through the cutting structure 14.

[0038] A first screw rod 20 and a second screw rod 21 are rotatably installed on the fixing frame 1 along the length direction of the U-shaped plate 10. Sliders 22 are installed on both the first screw rod 20 and the second screw rod 21, and a clamping unit 3 is arranged on the slider 22.

[0039] The first screw rod 20 and the second screw rod 21 are connected by belt drive. The first screw rod 20 is driven to rotate by a motor (not shown in the figure), and the threads of the first screw rod 20 and the second screw rod 21 are opposite, ensuring that during the simultaneous rotation of the first screw rod 20 and the second screw rod 21, the sliders 22 on the first screw rod 20 and the second screw rod 21 move in opposite directions, so as to achieve the purpose that the clamping units 3 on the sliders 22 can clamp the wire rope alternately.

[0040] It should be noted that the sliders 22 on the first screw rod 20 and the second screw rod 21 are located at both ends of the fixed frame 1 in the initial state. The moving directions of the two sliders 22 are opposite, and the distance between the sliders 22 is the distance that the wire rope needs to be cut.

[0041] The cutting-off structure 14 will cooperate with the clamping unit 3. The clamping unit 3 on the first screw rod 20 will pull the wire rope to move within the C-shaped plate 10. At this time, the clamping unit 3 on the second screw rod 21 will move in the opposite direction. After the clamping unit 3 on the first screw rod 20 moves a certain distance, the clamping unit 3 on the second screw rod 21 will clamp the wire rope at one end close to the cutting-off structure 14. At this time, the cutting-off structure 14 will synchronously cut the wire rope, and the clamping unit 3 on the first screw rod 20 will release the clamping of the wire rope. The cut wire rope will fall out of the C-shaped plate 10 through the through groove 12 for collection.

[0042] Subsequently, the clamping unit 3 on the second screw rod 21 continues to pull the wire rope to move, while the clamping unit 3 on the first screw rod 20 will return to the initial position, clamp the wire rope again, and cooperate with the cutting-off structure 14 to cut the wire rope again. In this way, the non-stop cutting of the wire rope is realized. Compared with the existing clamping and guiding structure, the waiting time for clamping is reduced, and the wire rope can also be pulled to move, improving the cutting efficiency of the wire rope.

[0043] Refer to Figure 1 、 Figure 4 and Figure 8 As shown in the figure, it is a schematic structural diagram of the structure for clamping the wire rope; specifically, the clamping unit 3 includes a fixed rod 30 and a sliding rod 31. The sliding rod 31 is slidably arranged on the fixed rod 30 along the height direction of the fixed rod 30. An installation rod is connected to the sliding rod 31, and clamping rods 32 are symmetrically hinged and installed on the installation rod. Clamping plates 33 are arranged on the clamping rods 32 through springs.

[0044] The functions of setting the fixed rod 30 and the sliding rod 31 are as follows: during the process of clamping the wire rope, the sliding rod 31 is in an extended state, and the clamping unit 3 on the sliding rod 31 will extend into the C-shaped plate 10. When one of the clamping units 3 does not clamp the wire rope and needs to return to the initial position, the clamping unit 3 needs to rise and not be in the C-shaped plate 10 to prevent affecting the movement of the other clamping unit 3 during the movement. Therefore, the sliding rod 31 needs to extend into the fixed rod 30 at this time.

[0045] When the sliding rod 31 slides down on the fixed rod 30 and approaches the wire rope, the two clamping rods 32 will approach each other to clamp the wire rope. By driving the corresponding sliders 22 through the first screw rod 20 and the second screw rod 21 to drive the fixed rod 30 to move, the wire rope can be pulled by the clamping rods 32.

[0046] It should be noted that the middle part of the fixed rod 30 on the slider 22 connected to the second screw 21 is bent, which can avoid the first screw 20 during the movement process, preventing the fixed rod 30 on the slider 22 connected to the second screw 21 from conflicting with the first screw 20 during movement.

[0047] Refer to Figure 2 , Figure 3 and Figure 4 shown, which is the structural schematic diagram of the clamping unit 3; specifically, the clamping unit 3 further includes a control member 34. The control member 34 includes a control rack 340. The control rack 340 is installed at the lower end of the fixed rod 30. Control gears 341 are symmetrically and rotatably installed on the sliding rod 31. The control gears 341 are connected to the hinge shafts of the clamping rods 32, and the control gears 341 are meshed with the control rack 340.

[0048] When the sliding rod 31 descends, the control gears 341 on the sliding rod 31 will come into contact with the control rack 340. The control rack 340 drives the clamping rods 32 to rotate in the reverse direction. The ends of the two clamping rods 32 away from the fixed rod 30 approach each other, and gradually approach the steel wire rope during the descending process until reaching the bottommost position. The steel wire rope is clamped by the clamping plates 33 on the two clamping rods 32.

[0049] Conversely, when it is necessary to release the clamping of the steel wire rope by the clamping plate 33, the sliding rod 31 ascends. At this time, the control gears 341 will rotate in the reverse direction under the reverse action of the control rack 340, and the ends of the two clamping rods 32 away from the fixed rod 30 will move away from each other, releasing the clamping of the steel wire rope.

[0050] Refer to Figure 2 , Figure 3 and Figure 4 shown, which is the structural schematic diagram for driving the sliding rod 31 to slide; specifically, a driving member 4 for driving the sliding rod 31 to move up and down on the fixed rod 30 is further installed on the fixed frame 1. The driving member 4 includes a driving rack 40. The driving rack 40 is arranged at the end of the sliding rod 31 away from the slider 22. Driving gears 41 that are movably meshed with the driving rack 40 are respectively arranged on both ends of the U-shaped plate 10 of the fixed frame 1 through brackets.

[0051] Through the cooperation of the driving gear 41 and the driving rack 40, the sliding rod 31 connected to the driving rack 40 moves up and down.

[0052] A telescopic shaft is installed along the length direction of the end of the U-shaped plate 10 away from the cutting structure 14 through a bracket, and a mounting shaft is installed along the length direction of the end close to the cutting structure 14 through a bracket. The two driving gears 41 are respectively arranged at the opposite ends of the telescopic shaft and the mounting shaft, and the telescopic shaft and the mounting shaft are传动连接(原文此处表述有误,推测是“传动连接”,英文为“transmission connection”) through a bevel gear set (shown in Figure 7 ), realizing that the rotational directions of the telescopic shaft and the mounting shaft are opposite.

[0053] The installation shaft is rotated by an external drive (such as a motor, etc.). The bevel gear set is used to drive the telescopic shaft and the installation shaft to rotate in opposite directions. When the clamping units 3 on the first screw 20 and the second screw 21 approach the drive gear 41 on the installation shaft, the slide bar 31 connected to the drive rack 40 can be controlled to descend, forcing the clamping plate 33 on the clamping rod 32 to clamp the steel wire rope. Conversely, when the clamping unit 3 approaches the drive gear 41 on the telescopic shaft, the slide bar 31 connected to the drive rack 40 can be controlled to ascend, forcing the clamping plate 33 on the clamping rod 32 to release the clamping of the steel wire rope.

[0054] Refer to Figure 5 As shown, it is a schematic structural diagram of cutting the steel wire rope. Specifically, the cutting structure 14 includes a tool holder 140. The tool holder 140 is slidably arranged below the cutter groove 13 along the height direction of the fixed frame 1. A cutting blade 141 is installed on the tool holder 140. An installation plate 142 is arranged on the fixed frame 1 along its width direction. The tool holder 140 is arranged on the installation plate 142 through a push spring.

[0055] A switch 143 for controlling the operation of the cutting blade 141 is installed on one side of the tool holder 140.

[0056] Under the action of the push spring, the tool holder 140 will enter the through groove 12. During this process, the switch 143 on the tool holder 140 will contact the inner side wall of the through groove 12, squeezing the switch 143 to turn on the cutting blade 141, causing the cutting blade 141 to rotate and cut off the steel wire rope in the U-shaped plate 10.

[0057] After cutting is completed, the tool holder 140 will drive the cutting blade 141 to descend. At this time, the side wall of the through groove 12 will squeeze the switch 143 again, causing the cutting blade 141 to stop rotating. When the steel wire rope is not being cut, the motor does not need to continuously operate, reducing power consumption.

[0058] Refer to Figure 3 and Figure 5 As shown, it is a schematic structural diagram for fixing the tool holder 140. Specifically, a moving member 5 for controlling the movement of the tool holder 140 is installed on the fixed frame 1. The moving member 5 includes a moving rack 50 installed on one side of the tool holder 140. A special-shaped moving rod 51 is slidably installed on the fixed frame 1 through a spring rod. In the initial state, the spring rod is in a contracted state. A rotating shaft is rotatably installed on the moving rod 51, and a moving gear 52 is connected to the rotating shaft. One end of the moving rod 51 above the U-shaped plate 10 is movably matched with the drive rack 40.

[0059] A clamping groove is formed on one side of the tool holder 140. A clamping block 53 that is movably matched with the clamping groove is installed on the moving rod 51.

[0060] In the initial state, the rotating shaft is driven to rotate by the motor. The moving gear 52 on the rotating shaft drives the moving rack 50 to rotate. The moving rack 50 gradually moves downward, and the moving rack 50 drives the tool rest 140 to move downward, away from the U-shaped plate 10, until the clamping groove on the tool rest 140 coincides with the clamping block 53. The tool rest 140 is limited by the clamping block 53. At this time, the rotation of the moving gear 52 will not mesh with the moving rack 50.

[0061] Refer to Figure 5 and Figure 6 As shown, it is a schematic structural diagram of the steel wire rope cut by the tool rest 140. Specifically, an inclined surface is provided at the bottom of the driving rack 40, which is inclined towards the moving rod 51. An inclined surface matching the driving rack 40 is also provided on the moving rod 51.

[0062] When the clamping rod 32 near the through groove 12 descends, it is necessary to cut the steel wire rope clamped by the other clamping rod 32 at this time. At this time, the sliding rod 31 on the fixed rod 30 near the through groove 12 descends. When the sliding rod 31 descends, the inclined surface of the driving rack 40 on the sliding rod 31 cooperates with the inclined surface on the moving rod 51, driving the moving rod 51 to slide. At this time, the clamping block 53 on the moving rod 51 slides out of the clamping groove, and the tool rest 140 loses the limit of the clamping groove. Under the action of the push spring, it quickly approaches the steel wire rope and cuts off the steel wire rope.

[0063] The push spring drives the cutting piece 141 on the tool rest 140 to quickly approach the steel wire rope and cut the steel wire rope. Compared with the traditional method of gradually approaching the steel wire rope for cutting, when cutting upward, it will cause a certain driving force on the steel wire rope, causing the steel wire rope to form an upward bulge at the cutting point, pulling the two ends of the steel wire rope, thereby affecting the cutting accuracy. The instantaneous cutting method can reduce the degree of deformation of the cutting part of the steel wire rope by the cutting piece 141, improve the cutting accuracy, and ensure that the length of the steel wire rope strictly meets the requirements.

[0064] Subsequently, the slider 22 on the first screw rod 20 drives the fixed rod 30 to move. Synchronously, the driving rack 40 on the sliding rod 31 moves synchronously. At this time, the inclined surface on the moving rod 51 disengages from the cooperation with the driving rack 40. At this time, the moving rod 51 returns to the initial position under the action of the spring rod.

[0065] It should be noted that when the moving rod 51 slides in cooperation with the driving rack 40, it will synchronously drive the rotating shaft on the moving rod 51 to move, and the moving gear 52 on the rotating shaft will move away from the moving rack 50. This makes the clamping block 53 on the moving rod 51 cancel the limit on the tool rest 140. The tool rest 140 will synchronously drive the moving rack 50 to rise. At this time, the moving gear 52 will not contact the moving rack 50, so there will be no conflict with its rising.

[0066] Refer to Figure 7 and Figure 8As shown, it is a schematic diagram of the structure that drives the slider 22 on the second screw rod 21 to rotate; specifically, The slider 22 on the first screw 20 is threadedly connected to it, and the slider 22 on the second screw 21 moves in cooperation with the second screw 21 through the guide member 7. The purpose of setting the guide member 7 is to prevent the clamping unit 3 on the slider 22 connected to the second screw 21 from colliding with the first screw 20 when the clamping unit 3 returns to the end close to the through groove 12. By controlling the rotation of the slider 22 on the first screw 20, the clamping unit 3 is flipped over, and when it returns to the end of the second screw 21 close to the through groove 12, it is flipped again so that the clamping unit 3 faces downward to clamp the wire rope.

[0067] The guide member 7 includes a sleeve 70, which is sleeved on the outside of the second screw rod 21. The slider 22 on the second screw rod 21 is slidably set inside the sleeve 70. The sleeve 70 is provided with a sliding groove 71 that passes through from top to bottom, and the fixing rod 30 on the slider 22 is slidably set in the sliding groove 71.

[0068] The fixed rod 30 on the second screw 21 connected to the slider 22 always slides inside the slide groove 71. When the second screw 21 rotates forward, the slider 22 threadedly connected thereto will not rotate due to the limitation of the fixed rod 30. The slider 22 will slide in the sleeve 70 driven by the second screw 21.

[0069] Semicircular guide grooves 72 are respectively provided at both ends of the sleeve 70, and the two guide grooves 72 are distributed on the same side. When the slider 22 moves to the guide groove 72 of the sleeve 70, the fixed rod 30 on the slider 22 will lose the limit of the slide groove 71, and the second screw 21 will rotate in the opposite direction. Since the slider 22 loses the matching limit of the fixed rod 30 and the slide groove 71, the slider 22 will rotate at a certain angle under the drive of the second screw 21. However, due to the effect of gravity, the force of the second screw 21 cannot completely cause the slider on the second screw 21 to complete the 180-degree flip. At this time, the fixed rod 30 on the slider 22 flipped at a certain angle will enter the guide groove 72. Since the guide groove 72 limits the fixed rod 30, the rotation of the second screw 21 cannot move the slider 22 threadedly connected thereto. Therefore, the reverse rotation of the second screw 21 can cause the slider 22 connected thereto to rotate synchronously, forcing the slider 22 to flip 180 degrees, and completing the overall flip of the clamping unit 3 on the second screw 21. After the slider 22 flips 180 degrees, the fixed rod 30 on the slider 22 will be blocked by the side wall of the slide groove 71 and can no longer rotate. At this time, the slider 22 threadedly connected to the second screw rod 21 will return to the end close to the cutting structure 14 with the cooperation of the fixed rod 30 and the second screw rod 21.

[0070] Similarly, when the slider 22 on the second screw 21 moves to the other end of the second screw 21, it cooperates with the guide groove 72 at the other end of the sleeve 70 again, forcing it to flip 180 degrees in the opposite direction, driving the clamping unit 3 on the second screw 21 to align with the wire rope below and clamp the wire rope again.

[0071] It should be noted that the sleeve 70 is a telescopic structure, so the position of the guide groove 72 on the sleeve 70 can be adjusted, and the flipping position of the slider 22 can be adjusted synchronously. According to different manufacturing needs, the distance at which the clamping unit 3 on the slider 22 of the second screw 21 releases the wire rope can be controlled, and the clamping unit 3 on the first screw 20 will synchronously clamp the wire rope at the other end, and the tool holder 140 will shear the wire rope at the other end, thereby controlling the length of the sleeve 70 to adjust the length of the wire rope sheared.

[0072] The telescopic rod is connected to the sleeve 70 through a connecting rod, that is, the driving gear 41 on the telescopic rod can adjust the position synchronously to ensure that before the slider 22 flips, the driving gear 41 can control the clamping unit 3 to release the clamping of the wire rope to ensure work efficiency.

[0073] Embodiment 2: On the basis of the first embodiment, in order to further improve the practicality of the present invention, a unified receiving piece 8 is also proposed, which is conducive to the unified storage of the steel wire ropes after cutting, and is convenient for subsequent bundling and taking.

[0074] Reference Fig. 9 As shown, it is a schematic diagram of the mechanism for collecting the cut wire rope; specifically, the unified collecting part 8 includes a storage box 80, on which a guide plate 81 is obliquely arranged, an extrusion plate 82 is slidably arranged inside the storage box 80 along its height direction, and an electric push rod 83 is symmetrically installed on the fixed frame 1 along the length direction of the storage box 80, and the telescopic end of the electric push rod 83 is connected to the extrusion plate 82.

[0075] The extrusion plate 82 is a telescopic structure.

[0076] The bottom of the storage box 80 is tilted, and the tilt angle is opposite to that of the guide plate 81 .

[0077] The cut wire rope will fall from the through slot 12 onto the guide plate 81, and then from the guide plate 81 into the storage box 80, and then fall to one side of the bottom of the storage box 80 through the inclined surface at the bottom of the storage box 80, and then the electric push rod 83 will shrink, and squeeze the wire rope with the squeezing plate 82, and simply fix the wire rope in the storage box 80, so that the subsequent staff can bundle and transport the collected wire ropes. The squeezing plate 82 will gradually shrink when it descends to adapt to the inclined surface at the bottom of the storage box 80 to ensure that there is no gap.

[0078] During operation: First step, before work starts, manually guide one end of the wire rope in a disc-shaped package between the first guide roller 60 and the second guide roller 61. By the relative rotation of the first guide roller 60 and the second guide roller 61, use the extrusion force generated by their relative rotation to send the wire rope into the inside of the C-shaped plate 10, and clamp the wire rope entering the inside of the C-shaped plate 10 through the control plate 11. Second step: The cutting structure 14 will cooperate with the clamping unit 3. The clamping unit 3 on the first screw 20 will pull the wire rope to move inside the C-shaped plate 10. At this time, the clamping unit 3 on the second screw 21 will move in the opposite direction. After the clamping unit 3 on the first screw 20 moves a certain distance, the clamping unit 3 on the second screw 21 will pick up the wire rope at one end close to the cutting structure 14.

[0079] Third step: The cutting structure 14 will simultaneously cut the wire rope, and the clamping unit 3 on the first screw 20 will release the clamping of the wire rope. The cut wire rope will be pushed out of the C-shaped plate 10 by the clamping unit 3 on the second screw 21 for collection.

[0080] Fourth step: The clamping unit 3 on the second screw 21 continues to pull the wire rope to move, while the clamping unit 3 on the first screw 20 will return to the initial position, pick up the wire rope again, and cooperate with the cutting structure 14 to cut the wire rope again. In this way, continuous cutting of the wire rope is achieved without stopping the machine. Compared with the existing structure, the waiting time for clamping is reduced, and the wire rope can also be pulled to move, improving the cutting efficiency of the wire rope.

[0081] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

[0082] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
