Description

Technical Field

[0001] This utility model relates to the field of cable tensile testing technology, and more specifically, to a tensile testing device for the production, processing and testing of wires and cables. Background Technology

[0002] In the production and processing of wires and cables, quality inspection is a key link to ensure product quality and safety. Among them, tensile testing is an important means of evaluating the strength, toughness and durability of cable materials, and is crucial for preventing cables from breaking or degrading in performance due to external forces during use.

[0003] Traditional cable tensile testing devices mostly employ direct tensioning, where one end is fixed and the other end is tensioned via a mechanical device to measure the cable's tensile strength. However, this method has significant limitations. Since the tension is usually applied only to one end of the cable, uneven stress may occur during the tensioning process, with one end bearing excessive tension while the other receives relatively less. This not only affects the accuracy of the test results but may also damage the cable due to localized stress concentration, failing to accurately reflect the overall mechanical properties of the cable. Furthermore, traditional tensile testing devices also have shortcomings in recording and analyzing tensile data. Most devices rely on mechanical measuring instruments or manual readings, which are not only cumbersome to operate and susceptible to human error but also limited in data accuracy and real-time performance, making it difficult to achieve full monitoring and accurate recording of the tensile process. Therefore, to address the above technical problems, a tensile testing device for wire and cable production and processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a tensile device for testing and processing of wires and cables. It can achieve uniform tensile testing on both sides of the cable, ensuring the uniformity of the test and preventing large errors in the test results due to excessive force on one end. Furthermore, the tensile force on the cable can be replaced by the tensile force on the tension spring, and the specific data can be displayed by the tension sensor connected to one end of the tension spring, which facilitates accurate recording of tensile test data.

[0005] This utility model is achieved through the following technical solution:

[0006] A tensile testing device for wire and cable production and processing includes a main body. An inner groove is formed on the upper side of the main body. Mounting grooves are formed on the left and right sides inside the inner groove. Two sets of symmetrically arranged sliding grooves are formed on the inner side of each mounting groove. A sliding plate is slidably connected to the inner side of each sliding groove. A semi-circular plate is fixedly connected between the two sets of sliding plates. A cable body is clamped on the outside of the semi-circular plate. A tension sensing mechanism is installed inside the mounting groove. A cavity is formed inside the main body. A guide groove is formed inside the sliding groove, and the guide groove communicates with the cavity. A tensile mechanism is installed inside the cavity.

[0007] Preferably, the cable body is abutted against an arc-shaped clamp, and a fixing bolt is threadedly connected between the arc-shaped clamp and the slide plate.

[0008] Preferably, the tension sensing mechanism includes a vertical plate, a tension sensor, a connecting block, and a tension spring. The vertical plate is fixedly connected to the inner center of the mounting groove, and the tension sensor is fixedly connected to both sides of the vertical plate.

[0009] Preferably, the connecting block is fixedly connected to the outside of the tension sensor, and the tension spring is fixedly connected between the connecting block and the slide plate.

[0010] Preferably, the tensioning mechanism includes a rotating rod and a connecting rope. The rotating rod is rotatably connected to the inside of the cavity, and the connecting rope is fixedly connected to both sides of the rotating rod. The end of the connecting rope passes through the guide groove and is fixedly connected to one side of the slide plate.

[0011] Preferably, a drive motor is fixedly connected to the outside of the main body of the device, and the rotating rod is fixedly connected to the drive motor.

[0012] Preferably, a mounting plate is fixedly connected to the bottom of the main body of the device, and mounting holes are provided on the outside of the mounting plate.

[0013] The technical solution of this utility model has at least the following beneficial effects:

[0014] This utility model proposes a tensile testing device for wire and cable production and processing. After the cable is clamped, the drive motor rotates the rotating rod to wind the connecting rope, which in turn causes the connecting rope to slide the slide plate in the groove. This controls the semi-circular plate to extend to both sides, uniformly stretching and testing the cable on both sides, ensuring the uniformity of the test and preventing large errors in the test results due to excessive force on one end. At the same time, when the slide plates separate and slide in the groove, the tension on the cable is replaced by the tension on the tension spring, and the specific data is displayed by the tension sensor connected to one end of the tension spring, which facilitates accurate recording of the tensile test data.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 1-6 This utility model proposes a tensile device for testing and processing of wires and cables, comprising a main body 1, an inner groove 2 on the upper side of the main body 1, mounting grooves 3 on the left and right sides inside the inner groove 2, two sets of symmetrically arranged sliding grooves 4 on the inner side of the mounting grooves 3, sliding plates 5 slidably connected to the inner side of the sliding grooves 4, a semi-circular plate 6 fixedly connected between the two sets of sliding plates 5, a cable body 7 clamped on the outside of the semi-circular plate 6, a tension sensing mechanism installed inside the mounting grooves 3, a cavity 14 on the inner side of the main body 1, a guide groove 15 on the inner side of the sliding grooves 4, and the guide groove 15 communicating with the cavity 14, and a tensile mechanism installed inside the cavity 14.

[0024] The cable body 7 is abutted by an arc-shaped clamp 8. The arc-shaped clamp 8 and the slide plate 5 are connected by a fixing bolt 9. By using the arc-shaped clamp 8 and the fixing bolt 9 together, the cable body 7 can be installed on the inner side of the semi-circular plate 6.

[0025] The tension sensing mechanism includes a vertical plate 10, a tension sensor 11, a connecting block 12, and a tension spring 13. The vertical plate 10 is fixedly connected to the inner center of the mounting groove 3, the tension sensor 11 is fixedly connected to both sides of the vertical plate 10, the connecting block 12 is fixedly connected to the outside of the tension sensor 11, and the tension spring 13 is fixedly connected between the connecting block 12 and the slide plate 5.

[0026] The tensioning mechanism includes a rotating rod 17 and a connecting rope 18. The rotating rod 17 is rotatably connected to the inside of the cavity 14, and the connecting rope 18 is fixedly connected to both sides of the rotating rod 17. The end of the connecting rope 18 passes through the guide groove 15 and is fixedly connected to one side of the slide plate 5.

[0027] The main body 1 of the device is externally fixedly connected to a drive motor 16, and the rotating rod 17 is fixedly connected to the drive motor 16. The rotation of the rotating rod 17 can be achieved by operating the drive motor 16.

[0029] The working principle of a tensile testing device for wire and cable production and processing based on an embodiment is as follows: When using this device to perform cable tensile testing, a section of cable is first cut, and both ends are installed in a semi-circular plate 6 using fixing bolts 9 and arc-shaped clamps 8. At this time, the drive motor 16 is turned to rotate the rotating rod 17, which drives the connecting rope 18 to wind. The connecting rope 18 then drives the slide plate 5 to slide in the slide groove 4, thereby controlling the semi-circular plate 6 to extend to both sides. This achieves uniform tensile testing on both sides of the cable, ensuring the uniformity of the test and preventing large errors in the test results due to excessive force on one end. At the same time, when the slide plates 5 separate and slide in the slide groove 4, the slide plates 5 will stretch the tension spring 13, thereby replacing the tension force on the cable with the tension force on the tension spring 13. The specific data is displayed by the tension sensor 11 connected to one end of the tension spring 13, which facilitates accurate recording of tensile test data.
