[0002] Wire and cable is an essential item in modern production and life. The quality of wire and cable is directly related to personal and property safety. To ensure the safe use of wire and cable, manufacturers and quality inspection departments will conduct various safety tests on wire and cable. Among them, the flexing testing machine is used to test the reliability and durability of wire and cable under bending and torsion. At present, during the process of reciprocating pulling and drawing wire and cable by the flexing testing machine, it is impossible to ensure whether the travel trolley that winds and moves the wire and cable moves to meet the test requirements each time, thus resulting in limited test accuracy of the wire and cable. Content of the Utility Model

[0018] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.
[0019] Please refer to Figure 1 As shown, a wire and cable flexing testing machine of the present utility model includes a testing machine table 1 and a travel trolley 2; a moving platform 11 is provided on the top of the testing machine table 1, the travel trolley 2 is slidably provided on the moving platform 11, a driver 12 for driving the travel trolley 2 to reciprocate on the moving platform 11 is provided on the testing machine table 1, and a travel sensor (not shown in the figure) for measuring the distance that the driver 12 drives the travel trolley 2 to move is provided on the driver 12.
[0020] Among them, the driver 12 can be a linear slide table, a conveyor belt or other devices that can be used to drive the travel trolley 2 to reciprocate on the moving platform 11. When the driver 12 is a conveyor belt, the travel sensor can detect the activity amount of the conveyor belt or the rotation amount of the drive shaft; when the driver 12 is a linear slide table, the travel sensor can detect the slide amount of the linear slide table or the rotation amount of the lead screw.
[0021] Working principle: The wire and cable 4 to be tested is tightened by a part of the wire body on the testing machine table through the counterweight 3, and the tightened part of the wire and cable to be tested is also wound around the travel trolley 2. Then, the driver 12 drives the travel trolley 2 to reciprocate on the moving platform 11 according to the number of test times. During the movement of the travel trolley 2, the displacement amount of the travel trolley 2 moving once is measured by the travel sensor. If the displacement amount of the travel trolley 2 measured by the travel sensor is not within the specified range, the number of cycle tests is not recorded.
[0022] Further, a timer (not shown in the figure) is provided on the travel trolley 2, and an induction mark (not shown in the figure) adapted to the timer is provided on the moving platform 11.
[0023] As can be seen from the above description, when the travel trolley 2 moves, the timer starts timing. After the travel trolley 2 moves into position, the induction mark on the moving platform 11 will trigger the timer to stop timing. At this time, the moving speed of the travel trolley 2 can be calculated according to the moving time measured by the timer and the displacement of the travel trolley 2 measured by the travel sensor. If the moving speed of the travel trolley 2 is not within the specified range, the number of cycle tests will not be recorded. To further improve the detection accuracy of the flexing testing machine.
[0024] Please refer to Figure 1 As shown, further, at least two pulleys 21 are provided on the travel trolley 2. Preferably, two pulleys 21 are provided on the travel trolley 2, and the axial center connection line of the pulleys 21 forms an angle of 40°, 45°, or 50° with the tabletop of the moving platform 11. Most preferably, the axial center connection line of the pulleys 21 forms an angle of 45° with the tabletop of the moving platform 11.
[0025] As can be seen from the above description, the wire and cable 4 to be tested is wound around the travel trolley 2 through the pulleys 21, and the axial center connection line of the pulleys 21 and the tabletop of the moving platform 11 form a fixture, which can effectively bend the wire and cable 4 to be tested.
[0026] Please refer to Figure 1 and Figure 2 As shown, further, the above-mentioned wire and cable flexing testing machine further includes a counterweight 3, and a fixture 31 for clamping the wire and cable 4 to be tested is provided on the counterweight 3.
[0027] As can be seen from the above description, the counterweight 3 is clamped on the wire and cable 4 to be tested through the fixture 31, so that a part of the wire body of the wire and cable 4 to be tested can be tightened on the testing machine table 1 under the action of the two counterweights 3.
[0028] Please refer to Figure 1 As shown, further, electrode posts 13 are provided on the testing machine table 1.
[0029] As can be seen from the above description, the wire ends at both ends of the wire and cable 4 to be tested are electrically connected to the electrode posts 13, so that during the test, it can be clearly known whether the wire and cable 4 to be tested is open-circuited or short-circuited.

A travel sensor (not shown in the figure) for measuring the moving distance of the travel trolley 2 driven by the driver 12 is arranged on the driver 12. A timer (not shown in the figure) is arranged on the travel trolley 2, and an induction mark (not shown in the figure) adapted to the timer is arranged on the moving platform 11. Two pulleys 21 are arranged on the travel trolley 2, and the axis connection line of the pulleys 21 forms a 45° angle with the tabletop of the moving platform 11. A clamp 31 for clamping the wire and cable 4 to be tested is arranged on the counterweight 3. An electrode post 13 is arranged on the testing machine platform 1.
[0032] Working principle: A part of the wire body of the wire and cable 4 to be tested is tightened on the testing machine platform through the counterweight 3, and the tightened part of the wire and cable to be tested is also wound around the travel trolley 2. Then, the driver 12 drives the travel trolley 2 to reciprocate on the moving platform 11 according to the number of test times. During the movement of the travel trolley 2, the displacement of the travel trolley 2 for a single movement is measured by the travel sensor. If the displacement of the travel trolley 2 measured by the travel sensor is not within the specified range, the number of cycle tests is not recorded. While the travel trolley 2 is moving, the timer starts timing. After the travel trolley 2 moves into position, the induction mark on the moving platform 11 will trigger the timer to stop timing. At this time, the moving speed of the travel trolley 2 can be calculated according to the moving time measured by the timer and the displacement of the travel trolley 2 measured by the travel sensor. If the moving speed of the travel trolley 2 is not within the specified range, the number of cycle tests is not recorded.
