Description

Technical Field

[0001] The present invention relates to the technical field of steel wire rope pressing, in particular to a pressing device for processing rotation-blocking super-large tonnage metal steel wire ropes and a use method thereof. Background Art

[0002] The anti-rotation super-large tonnage metal wire rope is a specially designed wire rope. Through the special lay pitch and lay direction design, it effectively prevents torsion and rotation. It is suitable for super-large tonnage lifting operations. The metal wire rope can withstand the tensile force of super-large tonnage, ensuring the safety and reliability of lifting operations. The unique structural design makes the wire rope less likely to rotate and twist during use, improving operational stability. During the pressing process of the wire rope, the wire rope needs to be placed in the pressing sleeve, and the pressing sleeve is placed in the mold for pressing. It is first pre-pressed and positioned with low pressure (about 20MPa), and then gradually increased to the target pressure (such as 1500KN for aluminum sleeves and higher pressure for steel sleeves), finally making the wire rope and the pressing sleeve integrated.

[0003] Generally speaking, before the pressing work is carried out, the wire rope is first bent by using a bending equipment, and then the pressing sleeve is put on the wire rope, and the processed wire rope is placed in a pressing machine for pressing. Since the pressing sleeve is manually put on the wire rope after the wire rope is bent, the initial position of the pressing sleeve on the wire rope may not be accurate. Since the inner diameter area of the pressing sleeve is initially larger than the cross-sectional area of the double-strand wire rope, the staff usually holds the wire rope and adjusts the position again during the pre-pressing positioning process. When the adjusted position is close to the designed position, it will not affect the quality of the pressed wire rope. However, due to the uncertainty of manual adjustment, when the adjusted position of the wire rope is greatly different from the designed position, it will be easy to cause loose pressing or product deformation in the subsequent pressing process. For this reason, we propose a pressing equipment for processing super-large tonnage metal wire rope with rotation resistance and a method for using the same. Summary of the Invention

[0011] Preferably, an annular frame is fixedly mounted on each of the steel sleeves, and a worm is mounted inside the annular frame and is rotatably connected to the inner wall thereof, wherein a worm wheel portion is also mounted inside the annular frame and is rotatably connected to the inner wall thereof, and the worm wheel portion is engaged with the worm, and one end of the worm is located outside the annular frame and is equipped with a knob.

[0014] Preferably, a flexible damping block is fixedly installed in the lower mold cavity, and a steel column is fixedly installed on the side of the lower mold away from the steel sleeve, and a rotating plate frame rotatably connected to the steel column is installed on the steel column, and bolts are installed on the rotating plate frame.

[0015] A method for using a pressing device for processing a rotation-blocking super-large tonnage metal wire rope comprises the following steps:

[0016] S1: First, adjust the position of the steel frame according to the design values: rotate the sliding shaft 90° in sequence so that the ball is no longer stuck on the movement trajectory of the block. Then pull the sliding shaft to adjust the position of the steel frame. After determining the position of the steel frame, rotate the sliding shaft 90° again. The ball is located in the locking area, and the sliding shaft is now restrained.

[0017] S2: Adjust the position of the roller according to the size of the wire rope: rotate the worm, and under the action of the meshing worm wheel, the worm wheel drives the screw to rotate, and the threaded sleeve is adjusted. During the position adjustment process, the transmission shaft drives the roller to contact the center area of the double-strand wire rope through the monitoring sleeve;

[0018] S3: Place the steel wire rope with the compression sleeve on the pressing machine, use the flexible damping block to limit the position of the compression sleeve, adjust the rotating plate frame so that the rotating plate frame is adjusted at an angle on the steel column, that is, align the bolts on the rotating plate frame with the compression sleeve, rotate the bolts so that the ends of the bolts contact the compression sleeve, and the compression sleeve is limited by the action of the flexible damping block and the bolts;

[0019] S4: A lifting platform is used to control the lower die for pre-pressing. During pre-pressing, the pressing sleeve is limited, and the length of the wire rope can be adjusted inside the pressing sleeve. During the adjustment process, the bent end of the wire rope contacts the monitoring shaft and makes it flush with the surface of the annular sleeve. During this process, the telescopic shaft on the annular panel moves along the trajectory of the arc-shaped groove. The monitoring shaft is used to rotate the annular platform, that is, the first magnetic plate rotates to the corresponding position of the iron block, generating an attractive force on the iron block. Under the action of the positioning shaft, the steel shaft limits the fine-tuning range of the wire rope;

[0020] S5: Using a pressing machine to press the pressing sleeve, during the pressing process, the roller part monitors whether the wire rope is twisted. After the pressing is completed, the bent end of the wire rope first leaves the contact surface of the monitoring shaft, and then the monitoring shaft is repeatedly applied with force and then leaves. Then, under the restraining effect of the arc-shaped groove body and the vertical groove body on the telescopic shaft, the first magnet and the second magnet are switched, so that the iron block passes through the positioning shaft by magnetic force, so that the steel shaft leaves the movement track of the wire rope, that is, the restraint of the wire rope is released;

[0021] S6. The staff takes out the pressed wire rope from the lower die.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention adjusts the position of the sliding shaft so that the steel plate frame can be adjusted synchronously with it, and utilizes the position relationship between the clamping block and the ball bearing so that the ball bearing can limit the position of the sliding shaft through the clamping block, thereby allowing the steel plate frame to limit the position of the steel wire rope. After the steel wire rope is initially limited under the action of the monitoring shaft, the annular panel controls the telescopic shaft to move along the trajectory of the arc trough and the vertical trough, so that the annular platform controls the first magnet and the second magnet to switch positions, thereby allowing the steel shaft to limit the position of the steel wire rope under the magnetic relationship with the iron block, so as to achieve the purpose of limiting the fine-tuning range of the steel wire rope, avoiding the situation that the pressing process is not firm or the product is deformed due to a large adjustment of the position, and improving the pressing quality of the steel wire rope.

[0024] 2. The present invention utilizes a roller portion to monitor the steel wire rope during the pressing process, and utilizes the roller portion to contact the steel wire rope, so that if the steel wire rope is twisted during the pressing process, a force will be applied to the roller portion, thereby causing the pressure sensor to have a value change under the action of the transmission shaft and the silicone shaft thereon. The value change of the pressure sensor can effectively determine whether the steel wire rope is twisted during the pressing process, thereby effectively monitoring the quality of the steel wire rope after pressing, and avoiding the condition of insufficient load-bearing capacity of the steel wire rope after pressing.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-13The present invention provides a technical solution: a pressing device for processing a large-tonnage metal wire rope with a rotation resistance, comprising a pressing machine 1 and a control platform 2 located on one side of the pressing machine 1, the pressing machine 1 also comprising a frame 11, a lifting platform 12 mounted on the frame 11, a lower die 13 mounted on the lifting platform 12, and an upper die 14 mounted on the frame 11, a flexible damping block 15 is fixedly installed in the cavity of the lower die 13, and a steel column 16 is fixedly installed on the side of the lower die 13 away from the steel sleeve 3, and a steel column 16 is installed on the steel column 16. There is a rotating plate frame 17 rotatably connected to it, and a bolt 18 is installed on the rotating plate frame 17. When the upper mold 14 just contacts the pressing sleeve, the pressing sleeve is prone to displacement or angle deviation due to uneven force at the beginning, thereby causing the position between the wire rope and the pressing sleeve to change again. In order to avoid the pressing sleeve from changing in the lower mold 13, the present invention has the following design: a flexible damping block 15 is fixedly installed in the cavity of the lower mold 13, and a steel column 16 is fixedly installed on the side of the lower mold 13 away from the steel sleeve 3, and the steel column 16 A rotating plate frame 17 is installed on the upper surface of the mold 13 and is connected to the rotating plate frame 17, and a bolt 18 is installed on the rotating plate frame 17; multiple sets of bolts 18 can be prepared to adapt to different sizes of press sleeves, and the flexible damping block 15 can also use a steel plate including a silicone layer, and the steel plate and the lower mold 13 are fixed by bolts 18; a steel sleeve 3 is symmetrically installed on one side of the lower mold 13, and a sliding shaft 31 is installed inside the steel sleeve 3, and a steel plate frame 32 is also provided at one end of the sliding shaft 31, wherein the steel plate frame 32 and the two sliding shafts are connected. The ends of the sliding shaft 31 are rotatably connected, and the steel plate frame 32 plays a positioning role; a plurality of clamping blocks 33 are symmetrically mounted on the sliding shaft 31. The plurality of clamping blocks 33 are evenly distributed on the sliding shaft 31, and adjacent clamping blocks 33 form a clamping area 34. The steel sleeve 3 is symmetrically mounted with mounting frames 35. A clamping shaft 36 is provided inside each of the two ends of each mounting frame 35, and a ball 37 is mounted on the end of the clamping shaft 36. A return spring 38 is connected to the inner wall of the clamping shaft 36 and the mounting frame 35;

[0041] Then, when it is necessary to adjust the position of the sliding shaft 31, the sliding shaft 31 is first rotated so that the clamping block 33 on the sliding shaft 31 leaves the corresponding position of the ball 37, that is, the ball 37 is not on the movement trajectory of the clamping block 33, and then the position of the sliding shaft 31 can be adjusted. It should be noted that the surface of the sliding shaft 31 in the present invention is provided with a scale groove, so that the staff can effectively know the length value of the steel plate frame 32 from the surface of the lower mold 13. After the position is determined, the sliding shaft 31 is rotated again by 90°. At this time, the ball 37 is on the movement trajectory of the clamping block 33, and the ball 37 is located in the clamping area 34 between the two clamping blocks 33 to hinder the movement of the clamping block 33, so that the sliding shaft 31 can be limited, that is, the position of the steel plate frame 32 is limited.

[0042] Furthermore, during the pressing process, if the pressure is uneven or the wire rope is unstable, the wire ropes are likely to be displaced relative to each other in the pressing sleeve, causing the rope body of the wire rope to be twisted, thereby reducing the bearing capacity. In order to prevent the wire rope from having insufficient bearing capacity after pressing, the present invention makes the following design: a transmission shaft 66 is installed inside the monitoring sleeve 65 and is slidably connected to its inner wall, and a roller part 67 is installed at the end of the transmission shaft 66 and is rotatably connected to it. The roller part 67 is in contact with the double-strand wire rope, wherein a spring body 68 is connected between the transmission shaft 66 and the inner wall of the monitoring sleeve 65, and a silicone shaft 69 is fixedly installed at one end of the transmission shaft 66 located inside the monitoring sleeve 65, and a pressure sensor 60 electrically connected to the control platform 2 is installed inside the monitoring sleeve 65, and the silicone shaft 69 is in contact with the pressure sensor 60. When there is a problem with the value change of the pressure sensor 60, the pressure sensor 60 transmits the information to the operating platform through an electrical signal to facilitate the staff to make adjustments.

[0043] In order to fine-tune the steel wire rope only within a certain range and avoid the situation that the pressing is not firm or the product is deformed due to the large adjustment position during the pressing process, the present invention has the following design: an annular sleeve 4 is fixedly installed in the central area of the steel plate frame 32, and an annular panel 41 is installed inside the annular sleeve 4 to be slidably connected to its inner wall, and a monitoring shaft 42 is also fixedly installed on the annular panel 41, and the monitoring shaft 42 passes through both ends of the annular sleeve 4, wherein a constant force spring 43 is connected between the annular panel 41 and the inner wall of the annular sleeve 4. During the process of adjusting the position of the steel wire rope, the monitoring shaft 42 is located on the movement trajectory of the steel wire rope, and a plurality of telescopic shafts 411 are also fixedly installed on the annular panel 41, as shown in the attached figure. Figure 9 As shown, a plurality of arc-shaped grooves 44 are provided on the inner wall of the annular sleeve 4, and adjacent arc-shaped grooves 44 are connected by vertical grooves 45. The monitoring shaft 42 is subjected to a force to drive the annular panel 41 to move in the annular sleeve 4, and the telescopic shaft 411 on the annular panel 41 enters the vertical groove 45 along the trajectory of the arc-shaped groove 44. With the center point of the annular sleeve 4 as the center of the circle, there is an angle difference between the extended lines of the midpoints of the two ends of the arc-shaped groove 44, and the angle difference is 90°, that is, when the telescopic shaft 411 moves along the trajectory of the arc-shaped groove 44, the annular panel 41 rotates by 90° each time. A guide plate frame 46 is fixedly installed in each vertical groove 45, and the guide plate frame 46 is located at the intersection of the vertical groove 45 and the arc-shaped groove 44. The side of the guide plate frame 46 located on the vertical groove 45 is an inclined surface, and the side close to the arc-shaped groove 44 is a right-angle surface;

[0044] Combined with attachment Figure 7 and attached Figure 8As shown, an annular stand 5 is also installed at one end of the annular sleeve 4 to be rotatably connected to its end. The annular stand 5 is sleeved on the monitoring shaft 42 and is slidably connected to the monitoring shaft 42. Two first magnets 51 and two second magnets 52 are provided on the annular stand 5. The first magnet 51 and the second magnet 52 are both connected to the annular stand 5 through a bracket 53. Figure 2 and attached Figure 5 As shown, a through slot 321 is symmetrically provided on the steel plate frame 32, and a positioning shaft 301 is installed in each through slot 321 and is slidably connected to its inner wall. An iron block 39 is fixedly installed at one end of the positioning shaft 301, and the magnetic poles of the iron block 39 and the first magnet 51 are opposite, and the magnetic poles of the iron block 39 and the second magnet 52 are the same. A steel shaft 30 is also fixedly installed at the end of the positioning shaft 301 away from the iron block 39. When the first magnet 51 rotates to the corresponding position of the iron block 39, an attraction force is generated on the iron block 39. , the positioning shaft 301 slides within the through groove 321, and the steel shaft 30 is located on the motion trajectory of the wire rope. It should be noted that, in the initial state, the second magnet 52 corresponds to the iron block 39 on the positioning shaft 301, and the second magnet 52 has the same magnetic pole as the iron block 39, and then the second magnet 52 produces a repulsive force on the iron block 39, and the steel shaft 30 will not be located on the motion trajectory of the wire rope. When the annular panel 41 rotates 90 degrees, the monitoring shaft 42 makes The annular stand 5 rotates synchronously by 90 degrees, and the first magnet 51 on the annular stand 5 rotates to the position corresponding to the iron block 39 on the positioning shaft 301, thereby generating an attractive force on the iron block 39 on the positioning shaft 301, that is, the positioning shaft 301 is adjusted in the through groove 321, so that the steel shaft 30 on the positioning shaft 301 moves to the motion trajectory of the wire rope, and then the fine-tuning range of the wire rope is from the surface of the annular sleeve 4 to the surface of the steel shaft 30. Within this range, when the wire rope and the steel shaft 30 are aligned, the wire rope can be adjusted to the desired position. When the surface of the shaft 30 is in contact, the steel wire rope will not contact the monitoring shaft 42, and the monitoring shaft 42 will be reset under the action of the constant force spring 43, that is, the telescopic shaft 411 on the annular panel 41 will move along the trajectory of the vertical groove 45 until it moves into the arc groove 44. During this process, the end of the telescopic shaft 411 will contact the inclined surface of the guide plate frame 46. When passing through the inclined surface of the guide plate frame 46, the telescopic shaft 411 will contract and then enter the arc groove 44.

[0045] Specifically, in actual use, the sliding shaft 31 is first rotated in sequence, that is, the sliding shaft 31 is rotated 90 degrees, so that the clamping block 33 on the sliding shaft 31 rotates synchronously with it. In this process, the sliding shaft 31 applies a force to the ball 37, so that the ball 37 is subjected to the force to move toward the inside of the mounting frame 35, and the ball 37 drives the clamping shaft 36 to squeeze the return spring 38 during the movement. Since the clamping block 33 is adjusted in angle with the sliding shaft 31, the ball 37 is no longer on the movement trajectory of the clamping block 33. Figure 5 As shown, the position of the sliding shaft 31 in the steel sleeve 3 is adjusted by pulling the steel plate frame 32. Since a scale groove is engraved on the sliding shaft 31, the length value of the steel plate frame 32 from the surface of the lower mold 13 can be effectively known; after moving to the designed value, the staff then rotates the sliding shaft 31 90°, that is, at this time, the ball 37 is located in the clamping area 34 between the two clamping blocks 33 under the action of the return spring 38, as shown in the attached figure. Figure 4 As shown, a plurality of balls 37 and a clamping shaft 36 are used to limit the sliding shaft 31, so that the sliding shaft 31 can be limited. It should be noted that if the balls 37 are in contact with the surface of the clamping block 33 and are not in the clamping area 34, the position of the sliding shaft 31 can be appropriately adjusted. It should be noted that appropriate adjustment of the position will not affect the pressing quality of the wire rope.

[0046] The worm 61 can then be rotated, and under the action of the meshing worm wheel 62, the worm wheel 62 drives the screw 63 to rotate, thereby adjusting the position of the threaded sleeve 64. During the position adjustment process, the threaded sleeve 64 drives the transmission shaft 66 to drive the roller 67 to contact the center area of the double-strand steel wire rope through the monitoring sleeve 65;

[0047] Then, when the position of the steel plate frame 32 is determined, the steel wire rope with the pressing sleeve is placed on the pressing machine 1, that is, the pressing sleeve is placed in the cavity of the lower die 13, and the attached Figure 12 and attached Figure 13As shown, a flexible damping block 15 can be fixedly installed on the lower mold 13, and the flexible damping block 15 is used to limit the position of the pressing sleeve. Since the flexible damping block 15 is fixedly installed in the cavity of the lower mold 13, when the pressing sleeve contacts the flexible damping block 15, the distance of the pressing sleeve in the lower mold 13 is limited. When the upper mold 14 just contacts the pressing sleeve, the pressing sleeve is easily displaced by the force (that is, the force is uneven at the beginning). In order to avoid the displacement of the pressing sleeve in the lower mold 13, when the pressing sleeve contacts the flexible damping block 15, the staff can rotate the rotating plate frame 17 so that the rotating plate frame 17 is in the lower mold 13. The angle of the steel column 16 is adjusted, that is, the bolt 18 on the rotating plate frame 17 is aligned with the pressing sleeve, and the bolt 18 is rotated so that the end of the bolt 18 contacts the pressing sleeve. It is further explained that a silicone sleeve can be installed on the end of the bolt 18, so that the pressing sleeve can have a certain range of deformation ability during the pressing process, and then the pressing sleeve is limited under the action of the flexible damping block 15 and the bolt 18. Then, the lifting platform 12 is used to control the lower mold 13 for pre-pressing. During pre-pressing, the pressing sleeve is limited. Since the inner diameter of the pressing sleeve is larger than the inner diameter of the double-strand steel wire rope, the steel wire rope can be extended in the pressing sleeve during the pre-pressing process. The adjustment is to make the bent end of the wire rope move toward the surface of the steel plate frame 32. During the movement, the bent end of the wire rope contacts the monitoring shaft 42 and exerts a force on it, so that the monitoring shaft 42 moves into the annular sleeve 4 until the monitoring shaft 42 is flush with the surface of the annular sleeve 4. During the movement of the monitoring shaft 42, the annular panel 41 inside the annular sleeve 4 will move synchronously with it to squeeze the constant force spring 43, and during the movement of the annular panel 41, the telescopic shaft 411 on it will move along the trajectory of the arc groove 44, that is, the annular panel 4 During the movement, the constant force spring 43 is squeezed. During the movement of the telescopic shaft 411, since the side of the guide plate frame 46 close to the arc-shaped groove body 44 is a right-angled surface, the telescopic shaft 411 moves along the trajectory of the arc-shaped groove body 44 under the action of the guide plate frame 46, thereby rotating the annular panel 41. Since the annular panel 41 is slidably connected to the annular platform 5, the angle of the annular platform 5 is adjusted. As can be seen from the above, under the action of the arc-shaped groove body 44, the annular panel 41 rotates 90 degrees, thereby causing the annular platform 5 to rotate 90 degrees synchronously. Figure 6-9As shown, in the initial state, the second magnet 52 corresponds to the iron block 39 on the positioning shaft 301, and the second magnet 52 and the iron block 39 have the same magnetic pole, and then in the initial state, the second magnet 52 generates a repulsive force on the iron block 39. At this time, the steel shaft 30 at the other end of the positioning shaft 301 will not be located on the motion trajectory of the wire rope. When the annular panel 41 rotates 90°, the annular stand 5 is synchronously rotated 90° under the action of the monitoring shaft 42, and the first magnet 51 on the annular stand 5 rotates to the position corresponding to the iron block 39 on the positioning shaft 301, thereby generating an attractive force on the iron block 39 on the positioning shaft 301, that is, the positioning shaft 301 is adjusted in position in the through groove 321, so that the steel shaft 30 on the positioning shaft 301 moves to the motion trajectory of the wire rope, as shown in the attached figure. Figure 2 As shown, the steel wire rope is limited. At this time, the range of motion of the steel wire rope is from the surface of the annular sleeve 4 to the surface of the steel shaft 30. Within this range, the steel wire rope can be fine-tuned. At this time, the position of the steel wire rope is limited, and the staff can use the pressing machine 1 to press the pressing sleeve.

[0048] During the pressing process, if the pressure is uneven or the wire rope is unstable, the wire ropes are likely to be displaced relative to each other in the pressing sleeve, causing the rope body of the wire rope to be twisted, resulting in a reduction in the load-bearing capacity. When the roller portion 67 contacts the center area of the double-strand wire rope, if the wire rope is twisted, a force will be applied to the roller portion 67, so that one of the roller portions 67 drives the transmission shaft 66 to move toward the inside of the monitoring sleeve 65, causing the transmission shaft 66 to squeeze the spring body 68, and the silicone shaft 69 to increase the pressure on the pressure sensor 60. When the pressure of the pressure sensor 60 changes, the information is transmitted to the operating platform through an electrical signal to facilitate adjustments by the staff.

[0049] When the pressing is completed and the restriction on the wire rope needs to be released, the staff can pull the wire rope slightly to make the wire rope leave the contact with the monitoring shaft 42, and then the annular panel 41 is reset under the action of the constant force spring 43. During the resetting process, the telescopic shaft 411 on the annular panel 41 moves along the trajectory of the vertical slot 45, and then pushes the wire rope again, so that the wire rope continues to act on the monitoring shaft 42. The monitoring shaft 42 repeats the above operation, so that the second magnet 52 rotates to the corresponding position of the iron block 39 on the positioning shaft 301, and the second magnet 52 produces a repulsive force on the iron block 39, so that the steel shaft 30 at the other end of the positioning shaft 301 leaves the movement trajectory of the wire rope, thereby releasing the restriction on the wire rope, and the staff can take out the wire rope.

[0050] A method for using a pressing device for processing a rotation-blocking super-large tonnage metal wire rope comprises the following steps:

[0051] S1: First, adjust the position of the steel plate frame 32 according to the design values: rotate the sliding shaft 31 90 degrees in sequence so that the ball 37 no longer engages the movement trajectory of the block 33. Then, pull the sliding shaft 31 to adjust the position of the steel plate frame 32. After determining the position of the steel plate frame 32, rotate the sliding shaft 31 90 degrees again. The ball 37 is located in the engaging area 34. At this time, the sliding shaft 31 is restrained.

[0052] S2: Adjust the position of the roller portion 67 according to the size of the wire rope: rotate the worm 61, and under the action of the meshing worm wheel portion 62, the worm wheel portion 62 drives the screw 63 to rotate, and the threaded sleeve 64 is adjusted in position. During the position adjustment process, the threaded sleeve 64 drives the transmission shaft 66 to drive the roller portion 67 to contact the center area of the double-strand wire rope through the monitoring sleeve 65;

[0053] S3: Place the steel wire rope with the compression sleeve on the pressing machine 1, and use the flexible damping block 15 to limit the position of the compression sleeve. Adjust the rotating plate frame 17 so that the rotating plate frame 17 is adjusted at an angle on the steel column 16, that is, the bolt 18 on the rotating plate frame 17 is aligned with the compression sleeve, and rotate the bolt 18 so that the end of the bolt 18 contacts the compression sleeve. Under the action of the flexible damping block 15 and the bolt 18, the compression sleeve is limited.

[0054] S4: Use the lifting platform 12 to control the lower die 13 for pre-pressing. During pre-pressing, the pressing sleeve is limited, and the length of the wire rope can be adjusted in the pressing sleeve. During the adjustment process, the bent end of the wire rope contacts the monitoring shaft 42 and makes it flush with the surface of the annular sleeve 4. During this process, the telescopic shaft 411 on the annular panel 41 moves along the trajectory of the arc-shaped groove 44. The monitoring shaft 42 is used to rotate the annular stand 5, that is, the first magnetic plate rotates to the corresponding position of the iron block 39, generating an attractive force on the iron block 39. Under the action of the positioning shaft 301, the steel shaft 30 limits the fine-tuning range of the wire rope;

[0055] S5: The pressing sleeve is pressed by the pressing machine 1. During the pressing process, the roller part 67 monitors whether the wire rope is twisted. After the pressing is completed, the bent end of the wire rope first leaves the contact surface of the monitoring shaft 42, and then the monitoring shaft 42 is repeatedly applied with force and then leaves. Then, under the restraining effect of the arc-shaped groove body 44 and the vertical groove body 45 on the telescopic shaft 411, the first magnet 51 and the second magnet 52 are switched, so that the iron block 39 passes through the positioning shaft 301 by magnetic force, so that the steel shaft 30 leaves the movement track of the wire rope, that is, the restraint of the wire rope is released;

[0056] S6. The staff takes out the steel wire rope that has been pressed on the lower die 13.
