Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable toughness testing device. Background Technology

[0002] Cables may experience various mechanical stresses, bending, and tension during use. If these stresses exceed the cable material's bearing capacity, it may lead to cable damage or performance degradation.

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.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a toughness testing device for cable production, comprising: a housing 1; a vertical plate 4 slidably placed on the top of the housing 1, a driving part for driving the vertical plate 4 to slide back and forth is installed on the top of the housing 1, and two pulleys 5 of different heights are rotatably connected to the outer side of the vertical plate 4 for repeatedly bending the cable; a tensile testing part is placed on one side of the vertical plate 4, the tensile testing part includes a fixed clamp 7 slidably disposed and pressure sensors 10 respectively placed at both ends of the fixed clamp 7 for detecting the strength and hardness of the cable, and a top rod 8 is fixedly connected to one end of the fixed clamp 7.

[0024] It should be noted that this utility model is equipped with a controller and a corresponding operation panel. The two ends of the cable are fixed to the two ends of the housing 1 respectively. Then, the middle part of the cable is wrapped around the outside of the pulley 5 in a Z-shape. The vertical plate 4 is driven to reciprocate through the drive unit. The pulley 5 repeatedly bends the cable. A counter is installed at one end of the linear module 2 to monitor the number of reciprocating movements of the moving platform 3. After a certain number of reciprocating movements, the cable's power supply and appearance damage are detected. One end of the short cable is fixed to the fixing clamp 7 and the other end is fixed to the fixing clamp 17. The fixing clamp 7 is driven to move through the drive unit. The pressure of the fixing clamp 7 on the pressure sensor 10 is used to observe the tensile strength of the cable. The cable is vertically fixed to one side of the support rod 11. Then, the push rod 8 is driven to move towards the cable through the drive unit. The end of the push rod 8 is provided with an arc-shaped notch for engaging with the cable to clamp it. The cable is pressed by the push rod 8. The strength is judged by observing the pressure of the pressure sensor 10 and the deformation of the cable.

[0025] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, the driving unit is a linear module 2 fixed to the top of the housing 1. A moving platform 3 is fixed to the moving slide of the linear module 2. A vertical plate 4 is fixed to the top of the moving platform 3. A guide rod 16 is fixed to the top of the housing 1. The moving platform 3 is slidably connected to the guide rod 16. A fixing clamp 7 is slidably connected to the moving platform 3. A pressure sensor 10 is fixed to the moving platform 3.

[0026] It should be noted that both ends of the linear module 2 of this utility model are equipped with limit switches, which facilitates the linear module 2 to drive the moving platform 3 to reciprocate. Under the action of the guide rod 16, the moving platform 3 can be moved horizontally and reciprocally. The pressure sensor 10 is fixedly connected to the moving platform 3, and the fixing clamp 7 is slidably connected to the moving platform 3 through the guide rail. After the fixing clamp 7 receives external force, it contacts the pressure sensor 10 to determine the force applied by the fixing clamp 7 to the cable.

[0027] Please see Figure 1 , 2 As shown in Figure 3, two adjustment slots 6 are provided in the middle of the vertical plate 4. A slider is installed in the middle of the adjustment slot 6, and the pulley 5 is rotatably connected to the slider.

[0028] It should be noted that the slider of this utility model is fixed to the vertical plate 4 by bolts. The height of the pulley 5 is adjusted by tightening or loosening the bolts. In this way, the degree of cable bending can be adjusted by adjusting the height difference between the two pulleys 5, so that it can be adjusted as needed.

[0029] Please see Figure 2 , 4 As shown in Figure 5, support rod 21 and support rod 13 are fixedly connected to both ends of the box body 1, respectively. Pulley 22 is rotatably connected to the outer side of support rod 21 and support rod 13. Support rod 21 is located at the end facing the top rod 8. Two fixing clamps 35 are fixedly connected to the outer side of support rod 21 and the position corresponding to the top rod 8.

[0030] It should be noted that when both ends of the cable are fixed, the two ends of the cable are clamped and fixed in the middle of the fixing clamp 14, and then wrapped around the outside of the pulley 12. The middle of the cable is wrapped around the pulley 5. When testing the cable's bending resistance, the cable is vertically clamped between the two fixing clamps 15. The linear module 2 drives the moving platform 3, and the moving platform 3 drives the top rod 8 to move towards the middle of the vertical cable through the fixing clamp 7. The top rod 8 squeezes the cable, and the degree of bending after deformation is observed. The pressure applied by the fixing clamp 7 to the pressure sensor 10 is also observed.

[0031] Please see Figure 1 , 2 As shown in Figures 4 and 5, a fixing clip 14 is fixedly connected to the bottom of support rod 13 and support rod 21, which is located below pulley 22. A fixing clip 4 17 is fixedly connected to one side of support rod 13 at the position corresponding to fixing clip 7.

[0032] It should be noted that when performing a tensile test on the cable, the two ends of the cable are fixedly connected to the first fixed clamp 7 and the fourth fixed clamp 17 respectively. The top of the housing 1 is provided with scale lines. The linear module 2 stretches the cable through the moving table 3 and the first fixed clamp 7. Under the action of pulling, the first fixed clamp 7 applies pressure to the pressure sensor 10, so that the deformation of the cable under different pressure conditions can be observed.
