Description
Technical Field
[0001] This utility model belongs to the field of cable technology and relates to tensile testing, specifically a tensile testing device for cable production. Background Technology
[0002] A tensile testing device for cable production is a piece of equipment used to detect and measure the tensile force exerted on cables during the production process in real time. Its main function is to ensure that the strength and toughness of the cable materials meet standards, thereby guaranteeing the quality and performance of the cable. This device can perform quality control, monitor production processes, ensure safety, and has data recording and analysis functions, providing a basis for quality assessment and improvement. It generally consists of sensors, a display, and a control system, providing accurate tensile force measurements to ensure the reliability and safety of cables during production and use.
[0003] However, most existing cable manufacturing tensile testing devices test cables by applying linear tensile force. Since cables may also be subjected to torsional forces in actual applications, a single linear tensile force test cannot fully reflect the cable's load-bearing capacity in real environments. Therefore, this problem needs to be solved. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tensile testing device for cable production. The technical problem to be solved by this utility model is that when testing cables, most tests are conducted by linear tensile force. However, cables may also be subjected to torsional forces in actual applications, so a single linear tensile force test cannot fully reflect the cable's load-bearing capacity in real environments.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tensile testing device for cable production includes a base. Two fixed plates are symmetrically fixed to the top of the base, and a common support seat is provided between the two fixed plates. Each of the two fixed plates has a limiting mechanism on one side for restricting the support seat. A first placement groove is formed on the top of the support seat, and an opening is formed on one side of the first placement groove. A first clamping plate is slidably connected inside the first placement groove on the side away from the opening. A moving mechanism for moving the first clamping plate is provided on the surface of the first clamping plate on the side away from the opening. A fixed seat is fixedly connected to the top of the base on the side away from the fixed plates. An adjusting cylinder is fixedly connected inside the fixed seat. A connecting seat is provided on the surface of the adjusting cylinder near the support seat. A fixing mechanism for fixing the cable is provided on the surface of the connecting seat near the support seat. Two adjusting rollers are symmetrically fixed to the surface of the connecting seat. Two second adjusting grooves are formed inside the adjusting cylinder, and the two second adjusting grooves are centrally symmetrical. First adjusting grooves are formed at both ends of each of the two second adjusting grooves. The adjusting rollers are configured to cooperate with the first and second adjusting grooves. A displacement mechanism for displacing the connecting seat is provided inside the adjusting cylinder. The adjustment rollers ensure that the cable will generate a torsional force during the testing process.
[0007] As a further embodiment of this utility model, the limiting mechanism includes a slide groove, which is opened on one side of the fixed plate. Two limiting rods are fixedly connected inside the fixed plate. The support seat is slidably sleeved on the surface of the two limiting rods. A pressure sensor is fixedly connected to the surface of the support seat near the adjusting cylinder. The other end of the pressure sensor is fixedly connected to one side inside the slide groove. By setting the limiting rods, the support seat can be moved forward stably.
[0008] As a further embodiment of this utility model, the moving mechanism includes a first lead screw, which is fixedly connected to one side of the first clamping plate and slidably connected to one side of the support base. A first worm gear is rotatably connected to the surface of the support base near the first lead screw. The first worm gear is slidably sleeved on the surface of the first lead screw. A first lead screw nut is provided inside the first worm gear near the first lead screw, and the first lead screw nut and the first lead screw are mutually engaged. A first worm is engaged on the surface of the first worm gear, and the first worm is rotatably connected to one side of the support base. By setting the first lead screw, the first clamping plate can be moved.
[0009] As a further embodiment of this utility model, the fixing mechanism includes a second placement groove, which is opened on one side of the connecting seat. A second clamping plate is slidably connected inside the second placement groove. A second lead screw is fixedly connected to the surface of the second clamping plate away from the connecting seat. A second worm gear is rotatably connected to the surface of the connecting seat near the second lead screw. The second worm gear is slidably sleeved on the surface of the second lead screw. A second lead screw nut is provided inside the second worm gear near the second lead screw, and the second lead screw nut and the second lead screw are mutually engaged. A second worm is engaged on the surface of the second worm gear, and the second worm is rotatably connected to one side of the connecting seat. The cable can be fixed by the setting of the second clamping plate.
[0010] As a further embodiment of this utility model, the displacement mechanism includes a docking plate, which is rotatably connected to one side of the connecting seat. A connecting member is fixedly connected to the surface of the docking plate away from the connecting seat. Two hydraulic rods are symmetrically fixedly connected to the surface of the connecting member near the adjusting cylinder. Both hydraulic rods are fixedly connected to the surface of the fixed seat. By setting the docking plate, it can be ensured that the connecting seat can still rotate during the movement.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. This utility model employs a technical solution where the cable is rotated by an adjusting roller. This ensures that the cable experiences torsional force during testing, effectively solving the problem that most cable testing relies on linear tension, which cannot fully reflect the cable's load-bearing capacity in real-world environments due to the potential for torsional forces in actual applications. An adjusting cylinder is positioned between two hydraulic rods, with two second adjusting grooves arranged symmetrically. Two adjusting rollers are symmetrically positioned on the surface of the connecting seat, each engaging with one of the second adjusting grooves. When the hydraulic rods move the connecting seat, the adjusting rollers move within the second adjusting grooves. Due to the shape of the second adjusting grooves, when the rollers are inside, they cause the connecting seat to rotate, allowing the cable to twist during testing, thus ensuring a more realistic assessment.

[0025] Working principle: In use, one end of the cable is placed inside the support base 2, and then the first worm 303 on one side of the support base 2 is rotated. A first lead screw 301 is installed on one side of the first worm 303, and the first lead screw 301 cooperates with the first worm wheel 302 through the first lead screw nut 304. Because the first lead screw 301 is installed on one side of the first clamping plate 3, and the support base 2 can also limit the first clamping plate 3, when the first worm wheel 302 rotates, the first lead screw 301 can drive the first clamping plate 3 to move forward, thereby achieving the purpose of fixing the cable.

A second clamping plate 503 is set inside the second placement groove 502, which can clamp and fix the other end of the cable. After both ends of the cable are fixed, the hydraulic rod 404 will start accordingly. A connector 403 is installed at the output end of the hydraulic rod 404. The connector 403 is connected to the connecting seat 5 via a mating plate 405. When the hydraulic rod 404 is activated, the connecting seat 5 can move one end of the cable. An adjusting cylinder 4 is provided between the two hydraulic rods 404. The adjusting cylinder 4 has two second adjusting grooves 402 inside, and the two second adjusting grooves 402 are centrally symmetrically arranged. Two adjusting rollers 501 are symmetrically arranged on the surface of the connecting seat 5. Both adjusting rollers 501 cooperate with the second adjusting grooves 402. When the hydraulic rod 404 moves the connecting seat 5, the adjusting rollers 501 move inside the second adjusting grooves 402. Due to the shape of the second adjusting grooves 402, when the adjusting rollers 501 are inside the second adjusting grooves 402, they will drive the connecting seat 5 to rotate, so that the cable can be twisted during the testing process to ensure that it is more in line with the actual situation.
