Description

Technical Field

[0001] This application relates to the field of wire testing technology, specifically a wire bending testing machine. Background Technology

[0002] Wire is a material used to transmit electrical signals, electricity, or other forms of energy, and it is widely used in electronics, electrical engineering, communications, and other fields. To evaluate the mechanical strength, toughness, and other properties of wire during bending, a wire bending tester is typically used to test the mechanical properties of the wire.

[0003] When testing wires, the wire sample is usually first mounted on the fixture of the testing machine to ensure that the sample is firmly fixed and to prevent it from falling off during the test. Then, the bending arm or support arm is started to rotate the wire to perform a bending test.

[0004] Conventional rotating devices can drive wires to move back and forth repeatedly within a certain range for testing. However, when encountering wires with large differences in thickness, in order to ensure the accuracy of the test results and the stability of the wires during the experiment, the entire testing device must be replaced. This results in poor flexibility of the testing device, a limited range of applications, and small enterprises cannot afford the equipment costs. Therefore, it is necessary to provide a wire bending testing machine to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figure 1 As shown, this application provides a wire bending testing machine, including a base 1. A stand 11 is fixedly installed on the upper end of the base 1. A first clamping member 2 is rotatably connected to the inner side of the upper end of the stand 11. The first clamping member 2 is used to clamp the upper end of the wire. At the same time, a second clamping member 3 is also installed on the inner side of the stand 11. The second clamping member 3 is located below the first clamping member 2 and is used to clamp the lower end of the wire. A driving mechanism 4 is also provided on the other side of the stand 11. The driving mechanism 4 is used to drive the first clamping member 2 to rotate, thereby driving the wire to bend.

[0034] like Figure 2 As shown, the first clamping member 2 has a connecting plate 21 rotatably connected to the upright frame 11. A mating sleeve 22 is fixedly installed on the outer side of the connecting plate 21. A circular groove is opened at the center end of the mating sleeve 22. At the same time, a protrusion 23 is also fixedly installed on the outer side of the connecting plate 21. The protrusion 23 is located directly above the mating sleeve 22. A fixing arc plate 24 is fixedly installed on the outer side of the protrusion 23.

[0035] Furthermore, an extension plate 26 is fixedly installed on the connecting plate 21. The extension plate 26 is located on one side of the protrusion 23. A second screw 27 is threadedly connected to the extension plate 26. A movable arc plate 25 is rotatably connected to one end of the second screw 27 near the fixed arc plate 24. The movable arc plate 25 is arranged opposite to the fixed arc plate 24. A nut 28 is fixedly installed on the other end of the second screw 27. Therefore, rotating the nut 28 can drive the second screw 27 to rotate, thereby adjusting the position of the movable arc plate 25. Thus, the wire to be tested is clamped and fixed by the movable arc plate 25 and the fixed arc plate 24.

[0036] The second clamping member 3 has a base plate 31 fixedly installed on the stand 11. A fixing clamp 32 is fixedly installed on one side of the upper end of the base plate 31, and a sliding groove 35 is opened through the base plate 31. A slider 36 is slidably connected in the sliding groove 35. A movable clamp 33 is fixedly installed on the upper end of the slider 36, and a standing block 37 is fixedly installed on the other side of the upper end of the base plate 31. A first screw 34 is threadedly connected to the standing block 37. One end of the first screw 34 is rotatably connected to the movable clamp 33, and a handle 38 is fixedly installed on the other end of the first screw 34. Therefore, by rotating the handle 38, the first screw 34 can be rotated, thereby causing the movable clamp 33 and the slider 36 to slide in the sliding groove 35, thereby clamping the lower end of the wire.

[0037] In this application, the upper surfaces of the fixed clip 32 and the movable clip 33 are curved outwards, which facilitates bending of the wire.

[0038] like Figures 3-4 As shown, the drive mechanism 4 has a drive shaft 41 rotatably connected to the other side of the upright 11. The other end of the drive shaft 41 is fixedly installed on the connecting plate 21. A drive plate 42 is fixedly installed on the outer end of the drive shaft 41. The drive plate 42 is vertically upward in the normal state. A push plate 43 is rotatably connected to the other end of the drive plate 42. A rotating plate 44 is hinged to the other end of the push plate 43. At the same time, an mounting shaft 45 is fixedly installed on the upright 11. The other end of the rotating plate 44 is rotatably connected to the mounting shaft 45.

[0039] Furthermore, a drive plate 46 is rotatably connected to the outer side of the middle section of the rotating plate 44, and a motor base 47 is fixedly installed on the upper end of the base 1. A drive motor 48 is fixedly installed on the upper end of the motor base 47. The drive motor 48 has an output shaft facing the drive plate 46. A main plate 49 is fixedly installed on the output shaft. A mating groove 491 is opened on the outer end of the main plate 49. A mating plate 494 is slidably connected in the mating groove 491. The other end of the mating plate 494 is hinged to the end of the drive plate 46.

[0040] Meanwhile, a threaded hole 492 is provided through the main board 49, and a plurality of mounting holes 493 are provided through the mating plate 494. The mounting holes 493 correspond to the threaded holes 492, and a fixing bolt 495 is internally threadedly connected to one of the mounting holes 493. The mating plate 494 and the main board 49 are fixed by the fixing bolt 495.

[0041] In summary: When conducting a bending test on the wire, the wire is first clamped and fixed by the first clamping member 2 and the second clamping member 3. Then, the drive motor 48 is started to drive the main board 49 to rotate. The rotation of the main board 49 pushes the drive plate 46 to move outward, and at the same time pushes the rotating plate 44 to rotate, and pushes the push plate 43 outward, so that the drive plate 42 and the drive shaft 41 rotate, thereby driving the connecting plate 21 to rotate the first clamping member 2 as a whole, so that the wire can undergo a bending test.

[0042] When encountering wires with significantly different thicknesses, the fixing bolt 495 is removed, and the extension length of the mating plate 494 is adjusted according to the thickness of the wire. After adjustment, the fixing bolt 495 is inserted into the threaded hole 492 and the corresponding mounting hole 493 to fix it. Therefore, when the mating plate 494 extends a longer distance, the driving plate 46 pushes a larger range, thus driving the shaft 41 to rotate a larger amplitude. Conversely, when the mating plate 494 extends a shorter distance, the driving plate 46 pushes a smaller range, thus driving the shaft 41 to rotate a smaller amplitude.

[0043] Therefore, when encountering wires with significant differences in thickness, only the position of the mating plate 494 needs to be adjusted, without the need to replace the entire testing device. This improves the flexibility of the testing device, expands its application range, and makes it more convenient for small businesses to use.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
