Description

Technical Field

[0001] This utility model relates to the field of wire and cable bending test technology, specifically a wire and cable bending test machine. Background Technology

[0002] In the fields of power transmission and communication, wires and cables are core components, and their quality and performance directly affect the stable operation of the system. In practical applications, wires and cables often face complex external forces, especially bending and compression at different angles, which can easily damage the internal structure of the cable, thereby affecting its electrical performance and service life. Therefore, conducting multi-angle bending tests on wires and cables is a key means to ensure their quality and performance.

[0003] However, the fixing methods of current wire and cable bending test equipment are often cumbersome and difficult to quickly fix the cable, resulting in low testing efficiency. Moreover, the fixing stability is poor, and the cable is prone to displacement or loosening during the test. This not only causes deviations in the test results but may also damage the test equipment. Most equipment can only perform single transverse or longitudinal bending tests on cables and cannot simulate the diverse stress conditions faced by cables in actual use, affecting the test results.

[0004] Therefore, it is urgent and of great significance to modify and develop a new type of bending tester that can quickly and securely fix cables and apply pressure to cables from different directions as needed to achieve multi-directional testing of cables. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire and cable bending test machine, comprising a base plate, a worktable fixedly connected to the top of the base plate via support legs, two square slots formed on the left side of the top of the worktable, clamping plates provided on the front and rear sides of the top of the square slots, the two clamping plates being symmetrically arranged, extension rods fixedly connected to the left and right sides of the bottom of the clamping plates, the surfaces of the extension rods being slidably connected to the inner walls of the square slots, a housing fixedly connected to the left side of the bottom of the worktable, the bottom ends of the extension rods extending into the housing, a forward and reverse motor fixedly connected to the rear of the housing, a bidirectional lead screw fixedly connected to the output end of the forward and reverse motor, the front end of the bidirectional lead screw being rotatably connected to the bottom of the worktable via a support plate, and a pair of threads connected to the front and rear sides of the surface of the bidirectional lead screw. The workbench is equipped with a nut seat, and both its left and right sides are fixedly connected to the bottom ends of the extension rods via connecting rods. A first electric telescopic rod is fixedly connected to the rear side of the top of the workbench, and a second electric telescopic rod, which is staggered with the first electric telescopic rod, is fixedly connected to the front side of the top of the workbench. The output ends of both the first and second electric telescopic rods are fixedly connected to a moving frame. The bottom of the moving frame is slidably connected to the top of the workbench. A push roller is rotatably connected to the inside of the moving frame via a rotating shaft. A horizontal groove running vertically through the workbench is provided on the right side, and an arc-shaped push plate is hinged to the left side of the inner wall of the groove. A connecting seat is slidably connected to the bottom of the arc-shaped push plate. A third electric telescopic rod is fixedly connected to the right side of the top of the base plate, and the output end of the third electric telescopic rod is hinged to the bottom of the connecting seat.

[0008] As a preferred embodiment of this utility model, a limiting top plate is fixedly connected to the top of the movable frame, and an anti-slip pad is fixedly connected to the bottom of the limiting top plate. The surface of the anti-slip pad and the surface of the pushing roller are both provided with anti-slip textures.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, the present invention provides a wire and cable bending tester, comprising a base plate 1, a worktable 2 fixedly connected to the top of the base plate 1 via support legs, two square grooves 3 formed on the left side of the top of the worktable 2, clamping plates 4 symmetrically arranged on the front and rear sides of the top of the square grooves 3, extension rods 5 fixedly connected to the left and right sides of the bottom of the clamping plates 4, the surfaces of the extension rods 5 slidingly connected to the inner walls of the square grooves 3, a housing 6 fixedly connected to the left side of the bottom of the worktable 2, the bottom ends of the extension rods 5 extending into the housing 6, a forward and reverse motor 7 fixedly connected to the rear of the housing 6, a bidirectional lead screw 8 fixedly connected to the output end of the forward and reverse motor 7, the front end of the bidirectional lead screw 8 rotatably connected to the bottom of the worktable 2 via a support plate, and symmetrically arranged nut seats 9 threadedly connected to the front and rear sides of the surface of the bidirectional lead screw 8. Both sides are fixedly connected to the bottom end of the extension rod 5 via connecting rods. The rear side of the top of the workbench 2 is fixedly connected to the first electric telescopic rod 10. The front side of the top of the workbench 2 is fixedly connected to the second electric telescopic rod 11, which is staggered with the first electric telescopic rod 10. The output ends of the first electric telescopic rod 10 and the second electric telescopic rod 11 are both fixedly connected to the moving frame 12. The bottom of the moving frame 12 is slidably connected to the top of the workbench 2. The inside of the moving frame 12 is rotatably connected to the push roller 13 via a rotating shaft. The right side of the workbench 2 has a horizontal groove that runs through it from top to bottom. The left side of the inner wall of the horizontal groove is hinged to the arc-shaped push plate 14. The bottom of the arc-shaped push plate 14 is slidably connected to the connecting seat 15. The right side of the top of the base plate 1 is fixedly connected to the third electric telescopic rod 16. The output end of the third electric telescopic rod 16 is hinged to the bottom of the connecting seat 15.

[0018] refer to Figure 2 Damping telescopic rods 17 are fixedly connected to the front and rear sides of the top left side of the workbench 2 via support plates. The inner end of the damping telescopic rod 17 is fixedly connected to the surface of the clamping plate 4. A stabilizing spring 18 is sleeved on the surface of the damping telescopic rod 17. The inner end of the stabilizing spring 18 is fixedly connected to the surface of the clamping plate 4, and the outer end of the stabilizing spring 18 is fixedly connected to the inner side of the support plate.

[0019] As a technical optimization of this utility model, the damping telescopic rod 17 and the stabilizing spring 18 enable the clamping plate 4 to have a certain buffer and elasticity when clamping the wires and cables. When the clamping plate 4 is subjected to external impact or vibration, the damping telescopic rod 17 can absorb some energy and reduce the shaking of the clamping plate 4, while the stabilizing spring 18 can provide a continuous inward pulling force to ensure that the clamping plate 4 is always tightly attached to the wires and cables, thereby enhancing the stability of the fixation and preventing the cable from shifting or loosening during the test, thus improving the accuracy and reliability of the test results.

[0020] refer to Figure 3 The top of the moving frame 12 is fixedly connected to a limiting top plate 19, and the bottom of the limiting top plate 19 is fixedly connected to an anti-slip pad 20. The surface of the anti-slip pad 20 and the surface of the push roller 13 are both provided with anti-slip textures.

[0021] As a technical optimization of this utility model, the setting of the limiting top plate 19 and the anti-slip pad 20 can prevent the wire and cable from tilting upward during the test, ensuring that the cable is always in full contact with the push roller 13. The anti-slip texture design increases the friction between the push roller 13 and the wire and cable, as well as between the anti-slip pad 20 and the wire and cable, so that when pressure is applied for bending test, the force can be transmitted more effectively, avoiding cable slippage, ensuring the smooth progress of the test, and further improving the accuracy and stability of the test.

[0022] refer to Figure 1 The front and rear sides of the top right side of the workbench 2 are fixedly connected to side guard plates 21 located on the front and rear sides of the transverse groove, and the inner side of the side guard plate 21 is fixedly connected to a sponge protective pad 22.

[0023] As a technical optimization of this utility model, the side guard plate 21 and the sponge protective pad 22 provide good protection for the longitudinal bending test of wires and cables. The side guard plate 21 can prevent the wires and cables from shifting to both sides during longitudinal bending, ensuring the directionality and accuracy of the test. The sponge protective pad 22 can buffer the collision between the wires and cables and the side guard plate 21, avoid scratching or damaging the cable surface, protect the integrity of the cable, and reduce the impact of cable damage on the test results, thereby improving the reliability of the test.

[0024] refer to Figure 4 The bottom of the movable frame 12 is fixedly connected to a T-shaped block 23. The top left and right sides of the worktable 2 are provided with sliding grooves 24 that cooperate with the T-shaped block 23. The surface of the T-shaped block 23 is slidably connected to the inner wall of the sliding groove 24.

[0025] As a technical optimization of this utility model, the T-shaped block 23 and the slide groove 24 are used in combination to play an important guiding and stabilizing role in the movement of the moving frame 12. The T-shaped block 23 slides in the slide groove 24, which restricts the movement direction of the moving frame 12, so that it can only move smoothly along the direction of the slide groove 24. This avoids the moving frame 12 from deviating or shaking during the movement, ensures that the push roller 13 can accurately apply pressure to the wire and cable, improves the accuracy of the test, extends the service life of the moving frame 12 and the worktable 2, and reduces the wear and tear and failure of the equipment.

[0026] refer to Figure 1 A rubber pad 25 is fixedly connected to the inner side of the clamping plate 4, and the surface of the rubber pad 25 is provided with friction texture.

[0027] As a technical optimization of this utility model, the clamping force of the clamp 4 on the wire and cable is enhanced by the setting of the rubber pad 25 on the inner side of the clamp 4 and the friction texture. The rubber pad 25 has a certain elasticity and flexibility, which can better fit the surface of the wire and cable and increase the contact area. The friction texture further improves the friction between the rubber pad 25 and the cable, so that the clamp 4 can fix the wire and cable more firmly, prevent the cable from sliding or loosening during the test, ensure the stability and accuracy of the test, and at the same time avoid the clamp 4 from damaging the surface of the cable.

[0028] The working principle and usage process of this utility model are as follows: In use, one end of the wire / cable is placed on the left side of the workbench 2, positioned inside the clamping plate 4. By starting the forward and reverse motor 7, the bidirectional lead screw 8 rotates, causing the nut seat 9 to move towards each other. This causes the clamping plate 4 to slide inward, clamping the head end of the wire / cable. The other end of the wire / cable is then placed on the top right side of the workbench 2. The first electric telescopic rod 10 and the second electric telescopic rod 11 are staggered. The bottom of the moving frame 12 at its output end is slidably connected to the top of the workbench 2. A push roller 13 is rotatably connected inside the moving frame 12 via a rotating shaft. When the first electric telescopic rod 10 and the second electric telescopic rod 11 extend, they drive the moving frame 12 and the push roller 13 to move, applying pressure to the wire / cable from different directions. For lateral bending tests, the first electric telescopic rod 10 and the second electric telescopic rod 11 can be activated simultaneously to apply pressure to both the front and rear sides of the wire and cable, causing it to bend into an S-shape, thus increasing the detection range. The push roller 13 can rotate within the moving frame 12, better adapting to the bending deformation of the cable. When longitudinal bending tests are required on the wire and cable, the first electric telescopic rod 10 and the second electric telescopic rod 11 are activated simultaneously, causing the two limiting top plates 19 to move to the top of the wire and cable, limiting the wire and cable. Then, the third electric telescopic rod 16 is activated to extend it, pushing the connecting seat 15 to move to the upper right, causing the arc-shaped push plate 14 to swing upward with the left side of the inner wall of the transverse groove as the center. Pressure is applied to the bottom right end of the wire and cable, causing it to bend upward, thus achieving multi-angle bending tests.
