Description

Technical Field

[0001] This utility model relates to the field of steel cable testing technology, and in particular to a high-strength steel cable pulling device. Background Technology

[0002] The essence of the drawing process is to utilize the plastic deformation characteristics of metals. By applying axial tension to the blank through the tapered channel of the drawing die, the metal wire / bar undergoes radial compression and axial extension plastic deformation within the die, thereby achieving a forming process that reduces the cross-section and increases the length. High-strength steel cables (such as bridge main cables, aerospace cables, deep-sea engineering cables, etc.) need to withstand extremely high loads, and therefore have stringent requirements for material strength, surface quality, and dimensional accuracy.

[0003] However, in traditional drawing equipment, the drawing force is constantly changing during operation. When the drawing force is insufficient, the contact pressure between the metal and the working zone of the die decreases, resulting in increased surface roughness and even "bamboo-like" patterns and micro-cracks in the core. When the drawing force exceeds the tensile strength of the billet, the probability of steel cable breakage increases significantly. The drawing force cannot be monitored, which affects the drawing quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-strength steel cable pulling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength steel cable pulling device, comprising a long shell frame, a support frame, a conical hole mold, and an industrial control computer. A pulling mechanism is fixedly installed inside the long shell frame, and a clamping mechanism is fixedly installed on the upper side of the pulling mechanism. The conical hole mold is fixedly installed at one end of the long shell frame. The clamping mechanism and the conical hole mold are at the same height. A cable feeding mechanism is fixedly installed on the upper side of the support frame, and the cable feeding mechanism is located on one side of the conical hole mold. The pulling mechanism includes a second servo motor, a lead screw, a guide rail assembly, a wire block, a tension sensor, and a movable block. The tension sensor is fixedly connected in the middle of the wire block and the movable block and electrically connected to the industrial control computer. The wire block is threadedly connected to the outer ring surface of the lead screw. The movable block is movably sleeved on the outside of the lead screw. Both the wire block and the movable block are slidably connected to the inside of the long shell frame through the guide rail assembly. The clamping mechanism is fixedly connected to the upper side of the movable block.

[0006] Preferably, the lead screw drive is connected to the output shaft of the second servo motor, which is fixedly installed inside the long housing.

[0007] Preferably, the clamping mechanism includes a clamping block, a bidirectional screw, and a rod seat. The rod seat is fixedly connected to the upper side of the movable block, and the bidirectional screw is rotatably connected inside the rod seat.

[0008] Preferably, the two sets of mirror-symmetrical clamping blocks are threadedly connected to the two sets of threaded areas of the bidirectional screw, and the lower ends of the two sets of clamping blocks are slidably engaged with the inner side of the rod seat.

[0009] Preferably, the cable-laying mechanism includes a roller frame, a first servo motor, a gear, an internal gear ring, a steel cable roller, and an auxiliary roller. The auxiliary roller is rotatably mounted at the end of the roller frame, and the lower end of the auxiliary roller is at the same height as the lower end of the tapered hole mold.

[0010] Preferably, the steel cable roller is parallel to and rotatably connected to the upper side of the roller frame with the auxiliary roller, the first servo motor is fixedly installed on the upper side of the roller frame, and the gear is fixedly installed on the output shaft of the first servo motor.

[0011] Preferably, the internal gear ring is fixedly connected to one side of the steel cable roller, and the gear meshes with the internal gear ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, after the steel cable end is extruded, it extends out of the conical hole mold. The clamping mechanism holds the steel cable end, and the pulling mechanism is controlled by the industrial control computer to pull the steel cable end to move. Under the action of the conical hole mold, the steel cable material undergoes plastic deformation, completing the pulling process. During the pulling process, the tensile force data obtained by the tensile force sensor is transmitted to the industrial control computer and displayed on the display screen of the industrial control computer. The operator can monitor the pulling force in real time and avoid the pulling force being too large or too small, thereby effectively ensuring the pulling quality.

[0014] 2. In this utility model, the first servo motor drives the gear to rotate, thereby meshing the internal gear ring, which in turn drives the steel cable roller to rotate, winding the steel cable material to be pulled. The end of the steel cable passes through the lower end of the auxiliary roller and passes through the conical hole mold. In the initial state, the end of the steel cable has been squeezed and extends out of the conical hole mold. The lower edge of the auxiliary roller and the lower edge of the conical hole mold are at the same height. The steel cable material is limited by the groove of the auxiliary roller, thereby entering the conical hole mold horizontally, ensuring that the steel cable material is always located in the central area of ​​the conical hole mold and reducing the pulling error.

The lead block 64 is threaded to the outer ring surface of the lead screw 62, and the movable block 66 is movably sleeved on the outside of the lead screw 62. Both the lead block 64 and the movable block 66 are slidably connected to the inside of the long frame 1 through the guide rail assembly 63. The clamping mechanism 5 is fixedly connected to the upper side of the movable block 66. The lead screw 62 is drivenly connected to the output shaft of the second servo motor 61. The second servo motor 61 is fixedly installed inside the long frame 1. The clamping mechanism 5 includes a clamping block 51, a bidirectional screw 52, ​​and a rod seat 53. The rod seat 53 is fixedly connected to the upper side of the movable block 66. The bidirectional screw 52 is rotatably connected to the inside of the rod seat 53. Two sets of mirror-symmetrical clamping blocks 51 are threadedly connected to the two sets of threaded areas of the bidirectional screw 52. The lower ends of the two sets of clamping blocks 51 are slidably engaged with the inside of the rod seat 53.

[0023] The specific settings and functions of this embodiment are described below: In the initial state, after the steel cable end is extruded, it extends out of the conical hole mold 4. In the initial state, the clamping mechanism 5 is close to the conical hole mold 4, and the steel cable end is placed in the middle position of the two sets of clamping blocks 51. The bidirectional screw 52 is rotated. The two sets of threads of the bidirectional screw 52 are in opposite directions, so that the two sets of clamping blocks 51 move closer to each other and clamp the steel cable end. The second servo motor 61 is started by the industrial control computer 7. The second servo motor 61 drives the lead screw 62 to rotate inside the lead block 64. The lead block 64 is subjected to the meshing force generated by the rotation, thereby moving along the guide... The rail assembly 63 moves along its length, and under the connection of the tension sensor 65, a horizontal tension is applied to the movable block 66, causing the movable block 66 to move along the length of the rail assembly 63. This drives the clamping mechanism 5 and the clamped steel cable end to move. Under the action of the tapered hole mold 4, the steel cable material undergoes plastic deformation, completing the drawing process. During the drawing process, the tension data obtained by the tension sensor 65 is transmitted to the industrial control computer 7 and displayed on the screen of the industrial control computer 7. The operator can monitor the drawing force in real time and avoid the drawing force being too large or too small, thereby effectively ensuring the drawing quality.

[0024] Example 2: Figure 1 - Figure 4As shown, the cable laying mechanism 3 includes a roller frame 31, a first servo motor 32, a gear 33, an internal gear ring 34, a steel cable roller 35, and an auxiliary roller 36. The auxiliary roller 36 is rotatably mounted at the end of the roller frame 31. The lower end of the auxiliary roller 36 is at the same height as the lower end of the tapered hole mold 4. The steel cable roller 35 is parallel to the auxiliary roller 36 and rotatably connected to the upper side of the roller frame 31. The first servo motor 32 is fixedly mounted on the upper side of the roller frame 31. The gear 33 is fixedly mounted on the output shaft of the first servo motor 32. The internal gear ring 34 is fixedly connected to one side of the steel cable roller 35. The gear 33 and the internal gear ring 34 mesh.

[0025] The overall effect of this embodiment is as follows: First, the first servo motor 32 is started, which drives the gear 33 to rotate, thereby engaging the internal gear ring 34, which in turn drives the steel cable roller 35 to rotate, winding the steel cable material to be pulled. The end of the steel cable passes through the lower end of the auxiliary roller 36 and passes through the conical hole mold 4. In the initial state, the end of the steel cable has been squeezed and extends out of the conical hole mold 4. The lower edge of the auxiliary roller 36 and the lower edge of the conical hole mold 4 are at the same height. The steel cable material is limited by the groove of the auxiliary roller 36, thereby entering the conical hole mold 4 horizontally, ensuring that the steel cable material is always located in the central area of ​​the conical hole mold 4, and reducing the pulling error.

[0026] The operating method and working principle of this device are as follows: First, start the first servo motor 32. The first servo motor 32 drives the gear 33 to rotate, thereby engaging the internal gear ring 34, which in turn drives the steel cable roller 35 to rotate, winding the steel cable material to be pulled. The end of the steel cable passes through the lower end of the auxiliary roller 36 and through the conical hole mold 4. In the initial state, the end of the steel cable has been squeezed and extends out of the conical hole mold 4. In the initial state, the clamping mechanism 5 is close to the conical hole mold 4, and the end of the steel cable is placed in the middle position of the two sets of clamping blocks 51. Rotate the bidirectional screw 52. The two sets of threads of the bidirectional screw 52 are in opposite directions, so that the two sets of clamping blocks 51 move closer to each other and clamp the end of the steel cable. The second servo motor 61 is controlled by the industrial control computer 7. Upon startup, the second servo motor 61 drives the lead screw 62 to rotate inside the lead block 64. The lead block 64 is subjected to the meshing force generated by the rotation, thereby moving along the length direction of the guide rail assembly 63. Under the connection of the tension sensor 65, a horizontal tension is applied to the movable block 66, causing the movable block 66 to also move along the length direction of the guide rail assembly 63, thereby driving the clamping mechanism 5 and the clamped steel cable end to move. Under the action of the tapered hole mold 4, the steel cable material undergoes plastic deformation, completing the drawing process. During the drawing process, the tension data obtained by the tension sensor 65 is transmitted to the industrial control computer 7 and displayed on the display screen of the industrial control computer 7. The operator can monitor the drawing force in real time, thereby effectively ensuring the drawing quality.
