Description

Technical Field

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

[0002] With the sustained and rapid growth of China's economy, the wire and cable industry has gradually become the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. Globally, China's total wire and cable output value has surpassed that of the United States, making it the world's largest wire and cable producer. Along with the rapid development of China's wire and cable industry, the number of new enterprises has continued to rise, and the overall technical level of the industry has been greatly improved. In order to meet the qualified specifications of cables, it is necessary to test the bending toughness of cables before they leave the factory. At this time, it is necessary to use a toughness testing device to test the cable toughness.

[0003] In existing technologies, bending equipment is typically used to test the degree of bending of cables. However, when testing cables of different diameters and lengths, it is necessary to change the clamping device of the equipment to fix cables of different diameters, which is not only time-consuming but also labor-intensive. Therefore, we propose a cable toughness testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a toughness testing device for cable production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable toughness testing device includes a base, a mounting plate on the top of the base, a cavity inside the mounting plate, a bidirectional screw rotatably mounted in the cavity, two sliders slidably mounted on the mounting plate, the bidirectional screw passing through and threadedly connected to the two sliders, a fixing frame on the front outer wall of the two sliders, a sliding groove on the fixing frame, a sliding plate slidably mounted on the sliding groove, a pressing plate at the bottom of the sliding plate, a groove on the lower inner wall of the fixing frame for use with the pressing plate, a threaded hole through the fixing frame, a threaded rod threadedly connected to the threaded hole, the bottom of the threaded rod connected to the sliding plate via a rotating sleeve, a fixing plate on the front outer wall of the mounting plate, an electric push rod on the fixing plate, a mounting frame at the end of the telescopic arm at the bottom of the electric push rod, and a pressing roller on the mounting frame.

[0007] As a further embodiment of this utility model: the mounting plate is provided with a mounting cavity located on the rear side of the cavity, and a rotating shaft is rotatably mounted inside the mounting cavity. A first bevel gear is connected to the bidirectional screw inside the mounting cavity via a key, and a second bevel gear is connected to the rotating shaft via a key. The second bevel gear meshes with the first bevel gear.

[0008] As a further embodiment of this utility model: a worm gear is also provided on the rotating shaft below the second bevel gear via a key connection, and a worm is also rotatably provided in the mounting cavity, with the worm and the worm gear meshing with each other.

[0010] As a further improvement of this utility model, the base is also provided with a hollow groove.

[0011] As a further improvement of this utility model, a first handle is provided at the outer end of the worm gear.

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

[0013] 1. Under the action of the bidirectional screw and the slider, the distance between the left and right sliders can be adjusted to accommodate cables of different lengths. Under the action of the fixing frame, the sliding plate and the pressing plate, the cable can be firmly fixed in the detection position. It can not only meet the toughness detection requirements of cables of different sizes, but also adjust the detection length of the cable, thereby improving the applicability of the device.

[0020] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0021] Example

[0022] Please see Figures 1-4 In this embodiment of the utility model, a cable toughness testing device includes a base 1, a mounting plate 2 on the top of the base 1, a cavity inside the mounting plate 2, a bidirectional screw 3 rotatably disposed in the cavity, and two sliders 4 slidably disposed on the mounting plate 2. The bidirectional screw 3 passes through the two sliders 4 and is threadedly connected to the two sliders 4. At this time, rotating the bidirectional screw 3 can drive the two sliders 4 to move closer or further away.

[0023] The left and right sliders 4 are equipped with a fixing frame 15 on their front outer walls. The fixing frame 15 has a sliding groove, on which a sliding plate 16 slides. A pressing plate 17 is located at the bottom of the sliding plate 16. The inner wall of the fixing frame 15 has a groove for use with the pressing plate 17. With the help of the groove and the pressing plate 17, the device can better press and fix the cable, thereby ensuring the quality of subsequent cable toughness testing. The fixing frame 15 is also provided with a threaded hole, and a threaded rod 18 is provided in the threaded hole through the threaded connection. The bottom of the threaded rod 18 is connected to the sliding plate 16 through a rotating sleeve. Rotating the threaded rod 18 will drive the sliding plate 16 to move, thereby allowing the pressing plate 17 to press and fix the cable. It can also meet the pressing and fixing of cables of different sizes, thereby improving the applicability of the device to a certain extent. A second handle 1801 is provided at the top end of the threaded rod 18. Rotating the second handle 1801 will drive the threaded rod 18 to rotate, thereby using the pressing plate 17 to press and fix the cable.

[0024] A fixing plate 11 is also provided on the outer wall of the front side of the mounting plate 2. An electric push rod 12 is provided on the fixing plate 11. A mounting frame 13 is provided at the end of the telescopic arm at the bottom of the electric push rod 12. A pressing roller 14 is provided on the mounting frame 13. When it is necessary to test the toughness of the cable, the operator uses the pressing plate 17 to press and fix the cable, and then starts the electric push rod 12 to drive the pressing roller 14 downward through the mounting frame 13, thereby squeezing the cable downward and testing the toughness of the cable. A slot 101 is also provided on the base 1. Under the action of the slot 101, the cable can be pressed downward better, thereby ensuring the quality and efficiency of the device in testing the cable toughness.

[0025] Inside the mounting plate 2, a mounting cavity is located on the rear side of the cavity. Inside the mounting cavity, a rotating shaft 5 is rotatably mounted. A first bevel gear 6 is connected to the bidirectional screw 3 via a key inside the mounting cavity. A second bevel gear 7 is connected to the rotating shaft 5 via a key. The second bevel gear 7 meshes with the first bevel gear 6. Rotating the rotating shaft 5 will drive the bidirectional screw 3 to rotate through the second bevel gear 7 and the first bevel gear 6, thereby adjusting the distance between the left and right sliders 4, thus adjusting the clamping length of the cable. This allows for better testing of the cable's toughness and ensures the testing quality of the device.

[0026] A worm gear 8 is connected to the shaft 5 via a key and positioned below the second bevel gear 7. A worm 9 is also rotatably mounted in the mounting cavity. The worm 9 meshes with the worm gear 8. Rotating the worm 9 will drive the shaft 5 to rotate via the worm gear 8. Furthermore, due to the uniform self-locking function of the worm gear 8 and the worm 9, the position of the slider 4 can be fixed after adjustment, thus ensuring the quality of its clamping and fixing of the cable. A first handle 10 is provided at the outer end of the worm 9. Rotating the first handle 10 will drive the worm 9 to rotate.

[0027] In actual use, when staff perform toughness testing on cables, they rotate the first handle 10 according to the actual testing requirements. This, along with the worm gear 9, worm wheel 8, second bevel gear 7, rotating shaft 5, and first bevel gear 6, drives the bidirectional screw 3 to rotate, thereby adjusting the distance between the left and right sliders 4. This allows the device to better adjust the cable testing length, ensuring the quality of the cable toughness test. Furthermore, the worm wheel 8 and worm gear 9 have a self-locking function, which restricts the position of the sliders 4 after adjustment, thus ensuring the efficiency of the device. Once the distance between the sliders 4 is adjusted to the appropriate position, the staff can place the cable to be tested on the fixing frame 15 in front of the sliders 4. At this time, rotating the second handle 1801 drives the threaded rod 18 to rotate, causing the sliding plate 16 to move downwards. This, in conjunction with the fixing frame 15, clamps and fixes the cable, ensuring the quality of the cable clamping and fixing. Afterward, the staff activates the electric push rod 12. The telescopic arm of the electric push rod 12 will drive the mounting bracket 13 and the pressing roller 14 on it to move downward. The pressing roller 14 will gradually contact and squeeze the cable downward, simulating the pressure situation that the cable may encounter in actual use, thereby testing the cable's toughness.
