Problems solved by technology
[0003] At present, when detecting the stress of the cable, the machine is often used to drive part of the cable to bend back and forth, and the stress of the cable has been obtained. However, the use of the machine to drive the cable to bend cannot accurately obtain the limit value of the stress on the cable skin, and at the same time cannot Determine the stress value of the occlusal fracture of the cable, and then the characteristics of the actual use of the cable cannot be judged, which affects the actual use of the cable

The invention relates to a wire and cable stress test clamp, in particular to a side edge occlusion type for testing the cutting stress of a wire and cable sample. The device comprises a fixed frame, an occlusion mechanism used for occlusion of a cable is arranged in the fixed frame, an adjusting device used for driving the occlusion mechanism to occlude the cable is arranged at one end of the occlusion mechanism, and a tension meter used for detecting the occlusion force of the occlusion mechanism on the cable is arranged on one side of the adjusting device. The adjusting device is used for driving the occlusion mechanism to extrude and press the cable, and in the downward movement process of the occlusion mechanism, the tension hook of the tension meter is driven to move downwards, so the cable occlusion force of the occlusion mechanism can be read, and meanwhile, the position of the occlusion mechanism is finely adjusted through the arranged fine adjustment device; the downward moving amplitude of the occlusion mechanism is reduced through the fine adjustment device, the speed of occlusion of the fractured cable by the occlusion mechanism is slowed down, and a tester can record the stress borne by occlusion fracture of the cable.
Description
technical field [0001] The invention relates to a wire and cable stress test clip, in particular to a side-engaging type wire and cable sample cutting stress test clip. Background technique [0002] The cable is tested before use to ensure the normal use of the cable. The main way for cable manufacturers to test the cable is to perform a pull test. For cables used in special working environments, such as cables for mining shearers, Cables for towing cables and shield machines are frequently twisted, bent or even pulled. During the use of the cables, the cables and other objects often bite repeatedly, even when the cables and other objects cannot When repeatedly biting, the cable will break, so it is necessary to detect the stress of the cable, so as to find out the effect of the cable in the actual use environment and prevent danger during the use of the cable. [0003] At present, when detecting the stress of the cable, the machine is often used to drive part of the cable ...
