Description

Technical Field

[0001] This utility model relates to the field of copper wire tensile performance testing technology, specifically a copper wire tensile performance testing mechanism. Background Technology

[0002] In daily life, copper wire is used as a conductor. It has excellent electrical conductivity and is widely used in the manufacture of wires, cables, and brushes. It also has good thermal conductivity, making it suitable for manufacturing magnetic instruments and meters that require protection against magnetic interference, such as compasses and aviation instruments. Furthermore, it has excellent plasticity, making it easy to process by hot and cold pressure, and can be made into copper materials such as tubes, rods, wires, strips, strips, plates, and foils. Pure copper products include both smelted and processed products. When using copper wire as a conductor, quality testing is required during the copper wire production process, which necessitates the use of strength testing devices.

[0003] However, existing testing devices have complicated operating procedures for testing the tensile strength of copper wires. When stretching the copper wire, the two ends that are fixed to it are prone to loosening, which can easily lead to safety accidents. At the same time, when the copper wire suddenly breaks, the broken end may bounce up at high speed or break into pieces and fly out. The bounced copper wire may hit the operator, and the flying copper wire may cause eye injuries or abrasions and cuts to other parts of the body. Utility Model Content

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1-7 As shown, a copper wire tensile strength testing mechanism includes: a tensile testing instrument body 1, a fixed plate 11 fixedly installed on the top of the tensile testing instrument body 1, a movable plate 12 provided on the other side of the fixed plate 11, and mounting frames 13 respectively provided on opposite sides of the fixed plate 11 and the movable plate 12; a clamping assembly, which is provided on the two mounting frames 13 respectively, for quickly clamping and fixing the copper wire; and a protective assembly, which is provided on the top of the tensile testing instrument body 1, for improving the safety when testing the copper wire.

[0029] The tensile testing instrument body 1 has a moving groove 4 at the top near the moving plate 12. Screws b41 are rotatably connected to opposite ends inside the moving groove 4. A moving block 42 is slidably connected inside the moving groove 4. The moving block 42 is threaded to the outside of the screws b41. The top of the moving block 42 is connected to the bottom of the moving plate 12. A device cavity 43 is opened on one side of the moving groove 4. A cover plate 44 is provided on the top of the device cavity 43. A reduction motor 45 is fixedly installed inside the device cavity 43. One end of the drive shaft of the reduction motor 45 is connected to one end of the screws b41.

[0030] Among them, a tensile detector 5 is fixedly installed on one side of the fixed plate 11, and the output end of the tensile detector 5 is connected to the mounting frame 13 on one side. The top of the tensile tester body 1 is provided with a scale line 51.

[0031] When testing the tensile properties of copper wire, both ends of the copper wire are placed between two mounting frames 13, and then the two ends of the copper wire are fixed by the clamping assembly. Then, the reduction motor 45 is started to drive the screw b41 to rotate. When the screw b41 rotates, it engages with the moving block 42, which in turn drives the moving block 42 to move the moving plate 12 and moves the mounting frame 13 to one side, stretching the copper wire to lengthen it. The reduction motor 45 can reverse to drive the moving plate 12 back to the initial position. The tensile force detector 5 can detect the tensile force and display the detected tensile force on the display screen of the tensile tester body 1. At the same time, by observing the length of the copper wire stretched by the tensile force detector 5, the tensile properties of the copper wire can be known. The protective assembly can protect the operator during the test and prevent the flying debris from injuring the operator when the copper wire breaks.

[0032] Example 2

[0033] Based on Embodiment 1, the clamping assembly includes: a through hole 2, a screw a21, a clamping plate 22, a cavity 23, a gear a24, a gear b25, and a transmission chain 26. The mounting frame 13 has through holes 2 at both its top and bottom. A screw a21 is installed inside each through hole 2. A clamping plate 22 is fixedly installed at each opposite end of the two screws a21. A C-shaped cavity 23 is formed inside the mounting frame 13. Gears a24 are installed at both ends of the cavity 23. The two gears a24 are threadedly connected to the two screws a21. The cavity 23... Two gears b25 are provided on one side of the interior. A transmission chain 26 connects the two gears b25 and the two gears a24. A drive motor 27 is fixedly installed on the top of the mounting frame 13. The drive shaft of the drive motor 27 is connected to the rotating shaft of the gear b25 located at the top. A connecting rod 28 is fixedly connected between the shafts of the two gears b25. Two guide blocks 29 are fixedly connected to the inner wall of the through hole 2. Two symmetrically arranged guide grooves 210 are opened on the outside of the screw a21. The guide blocks 29 are located inside the guide grooves 210 respectively.

[0034] When clamping and fixing the copper wire, one end of the copper wire is placed in the mounting frame 13 on one side of the fixing plate 11, so that the copper wire is placed between the two clamping plates 22. Then, the drive motor 27 is started to drive the connected gear b25 to rotate. The connecting rod 28 drives the other gear b25 to rotate synchronously. The transmission chain 26 drives the two gears a24 to rotate. Since the upper and lower screws a21 have opposite threads, the threads of the two gears a24 are engaged with the two screws a21. The rotation of the gears a24 engages with the screws a21. Since the screws a21 are restricted by the guide block 29 and the guide groove 210, the two screws a21 can only move in the vertical direction. The relative movement of the two screws a21 pushes the two clamping plates 22 to clamp and fix the copper wire. The other end of the copper wire is clamped and fixed in the same way. When releasing the fixation of the copper wire, the drive motor 27 is controlled to rotate in the opposite direction, so that the upper and lower screws a21 move away from each other and separate, thus releasing the fixation of the copper wire.

[0035] Example 3

[0036] Based on Embodiment 1, the protective components include: a protective cover 3, a protective door 31, a fitting plate 32, a fitting groove 33, and a partition plate 34. The protective cover 3 is fixedly installed on the top of the tensile testing instrument body 1. The protective door 31 is rotatably connected between the opening of the protective cover 3 and the inner walls on both sides. The fitting plate 32 is fixedly connected to the inner walls on both sides of the protective door 31. Fitting grooves 33 are respectively opened on the inner walls on both sides of the opening of the protective cover 3. The partition plate 34 is fixedly installed on the outside of the fixed plate 11 and the movable plate 12.

[0037] When testing the copper wire, the protective door 31 is opened, the two ends of the copper wire are clamped and fixed, and then the protective door 31 is closed, so that the fitting plate 32 moves into the fitting groove 33 to support the protective door 31. The protective door 31 and the protective cover 3 activate the protective function to prevent debris from flying. The two partition plates 34 can prevent debris from falling into the moving groove 4. The protective door 31 and the protective cover 3 are made of transparent PC material, and the scale line 51 can be observed through the protective door 31 and the protective cover 3.
