Description

Technical Field

[0001] This utility model relates to the field of alloy copper wire testing technology, specifically to an alloy copper wire tensile strength tester. Background Technology

[0002] Copper wire is a common conductor material in daily production and processing. It is usually used in various types of cables. Depending on the application scenario and requirements, copper is also mixed with other metals to make alloy copper wire to improve the performance of the cables. During processing and production, products usually need to be tested, and tensile testing is a common test item.

[0003] However, in actual use, when the copper wire is subjected to tensile testing, the alloy copper wire often breaks at the moment of breakage, resulting in dangerous flying debris. Therefore, the metal copper wire needs to be protected during testing to prevent metal breakage and rebound when it breaks. At the same time, the device also needs to be easy to install and fix, and be suitable for installing and fixing copper wires of different sizes, so as to facilitate rapid tensile testing of different alloy copper wires. Utility Model Content

[0004] The purpose of this invention is to provide an alloy copper wire tensile tester, which solves the problems of insufficient protection when copper wire breaks and inconvenient installation, replacement and testing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an alloy copper wire tensile tester, comprising a mounting plate, a tensile gauge mounted on the top of the mounting plate, a top plate provided at the top of the tensile gauge, sliding strips fixedly connected to both sides of the top of the mounting plate near the tensile gauge, a protective cover rotatably connected to the top of the tensile gauge, and a drive assembly mounted at the bottom of the mounting plate. The top of the tension gauge is equipped with a pull rod, and the top of the pull rod is equipped with a rotating bolt, and both ends of the rotating bolt are threaded with clamping plates. Sliding blocks are fixedly connected to both ends of the top plate, and pressing plates are provided on both sides of the top of the top plate. A screw is threaded to one end of each pressing plate. The drive assembly includes a drive gear, both ends of which are meshed with driven gears, and a screw is fixedly connected through the interior of the driven gear.

[0006] Preferably, a connecting shaft is installed between the protective covers on both sides of the top of the tension gauge. The bottom of one side of the protective cover is rotatably connected to the tension gauge through the connecting shaft. An adjusting cover is slidably connected to the top of each protective cover. The ends of the two adjusting covers that are close to each other are rotatably connected to the bottom of the top plate through a rotating shaft.

[0007] Preferably, a receiving groove is provided on one side of the center of the top plate, the threads at both ends of the lead screw are reversed, the sliding block and the sliding strip are internally slidably connected, the sliding block and the outer wall of the lead screw are threadedly connected, and a mounting post is sleeved at the center of the lead screw, with the bottom of the mounting post slidably connected to the top of the top plate.

[0008] Preferably, a drive motor is mounted on the bottom of the drive gear, and the output shaft of the drive motor is fixedly connected to the center of the drive gear.

[0009] Preferably, the sliding bar has a groove on the side near the top plate, the sliding block is slidably connected to the groove inside the sliding bar, the screw is located inside the groove of the sliding bar, and the top ends of the two sliding bars are fixedly connected by a connecting bar.

[0010] Preferably, the two ends of the rotating bolt have opposite threads, and the bottom of the clamping plate is slidably connected to the top of the pull rod.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. The protective cover can be easily rotated to place the copper wire between the covers. The protective cover can easily block the copper wire, preventing accidental splashing and danger when it breaks. At the same time, because the top of the protective cover is slidably connected to an adjustable cover, the adjustable cover can be easily adjusted along with the opening and closing of the protective cover. Furthermore, because the top of the adjustable cover is rotatably connected to the top plate, the adjustable cover can be easily moved along with the top plate as it moves upward, thus ensuring that the copper wire is always inside the protective cover and the adjustable cover, making it safer.

[0012] 2. Rotating the rotating bolt moves the clamping plate closer, facilitating the clamping of copper wires of different sizes. It also allows for easy rotation of the protective cover and adjusting cover to place the copper wire between them. Since the top plate has a receiving groove on one side, rotating the extrusion plate to either side of the groove allows for easy placement of the copper wire inside. Rotating the screw then moves the extrusion plate closer to clamp the copper wire. The position of the mounting post can also be moved to adjust the screw position, thereby adjusting the position of the extrusion plate to offset it from the receiving groove, preventing the copper wire from slipping out during pulling. After testing, rotating the extrusion plate back to either side of the receiving groove releases the clamping mechanism, allowing for easy removal of the copper wire from the receiving groove. This process is very convenient. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-5 The apparatus shown is an alloy copper wire tensile tester, comprising a mounting plate 1, a tension gauge 2 mounted on the top of the mounting plate 1, a top plate 3 at the top of the tension gauge 2, sliding strips 4 fixedly connected to both sides of the top of the mounting plate 1 near the tension gauge 2, a protective cover 5 rotatably connected to the top of the tension gauge 2, and a drive assembly 6 mounted on the bottom of the mounting plate 1; a pull rod 201 mounted on the top of the tension gauge 2, a rotating bolt 203 mounted on the top of the pull rod 201, and clamping plates 202 threadedly connected to both ends of the rotating bolt 203; sliding blocks 301 fixedly connected to both ends of the top plate 3, and pressing plates 302 provided on both sides of the top of the top plate 3, with a lead screw 303 threadedly connected to one end of each pressing plate 302; the drive assembly 6 includes a drive gear 601, driven gears 602 meshing at both ends of the drive gear 601, and a screw 401 fixedly connected through the interior of the driven gear 602.

[0018] When the screw 401 rotates, it can easily drive the sliding block 301 to move up and down, thereby driving the top plate 3 to move to the top, which in turn drives the top extrusion plate 302 to move to the top, thus pulling the copper wire. Since the bottom of the copper wire is fixed by the clamping plate 202, the pull rod 201 is pulled. The change of tension can be monitored by the tension gauge 2, thereby realizing the tension test of the alloy copper wire. The copper wire is placed between the protective covers 5, which can easily block the copper wire and prevent accidental splashing when it breaks, thus avoiding danger. The copper wire can be easily placed into the receiving groove. Then, rotating the screw 303 can drive the extrusion plate 302 to move closer and clamp the copper wire. The position of the mounting column 304 can also be moved to adjust the position of the screw 303, thereby adjusting the position of the extrusion plate 302, so that the extrusion plate 302 is misaligned with the receiving groove, preventing the copper wire from coming out of the receiving groove when pulled.

[0019] like Figure 1 , Figure 2 As shown, a connecting shaft is installed between the protective covers 5 on both sides of the top of the tension gauge 2. The bottom of one side of the protective cover 5 is rotatably connected to the tension gauge 2 through the connecting shaft. The top of the protective cover 5 is slidably connected to the adjusting cover 501. The two adjusting covers 501 are rotatably connected to the bottom of the top plate 3 through a rotating shaft. The protective cover 5 can be rotated easily to place the copper wire between the protective covers 5. The copper wire can be blocked by the protective cover 5 to avoid accidental splashing and danger when it breaks. At the same time, since the top of the protective cover 5 is slidably connected to the adjusting cover 501, the adjusting cover 501 can be easily adjusted with the opening and closing of the protective cover 5 during use.

[0020] like Figure 4 , Figure 5 As shown, a receiving groove is provided on one side of the center of the top plate 3. The threads at both ends of the lead screw 303 are reversed. The sliding block 301 is slidably connected to the inside of the sliding strip 4. The sliding block 301 is threadedly connected to the outer wall of the screw 401. An installation post 304 is sleeved at the center of the lead screw 303, and the bottom of the installation post 304 is slidably connected to the top of the top plate 3. The threads at both ends of the rotating bolt 203 are reversed. The bottom of the clamping plate 202 is slidably connected to the top of the pull rod 201. When the screw 401 rotates, it can easily drive the sliding block 301 to move up and down, thereby driving the top plate 3 to move to the top, thereby driving the top extrusion plate 302 to move to the top, thereby pulling the copper wire to move. Since the bottom of the copper wire is fixed by the clamping plate 202, the pull rod 201 is pulled. The change of tension can be monitored by the tension gauge 2, thereby realizing the tension test of the alloy copper wire.

[0021] like Figure 1 , Figure 4 As shown, a drive motor 603 is installed at the bottom of the drive gear 601. The output shaft of the drive motor 603 is fixedly connected to the center of the drive gear 601. A groove is provided on the side of the sliding bar 4 near the top plate 3. The sliding block 301 is slidably connected to the groove inside the sliding bar 4. The screw 401 is located inside the groove of the sliding bar 4, and the top ends of the two sliding bars 4 are fixedly connected by a connecting strip 402. When the drive motor 603 at the bottom is started, the drive gear 601 rotates, which drives the driven gear 602 to rotate, and then the screw 401 rotates accordingly.

[0022] In use, one end of the alloy copper wire can be easily placed between the clamping plates 202. Rotating the rotating bolt 203 brings the two clamping plates 202 closer together, thus pressing and fixing the alloy copper wire. Alternatively, the other end or the outer wall of the copper wire can be placed between the two pressing plates 302. Rotating the screw 303 brings the pressing plates 302 closer together, clamping and fixing the outer wall of the copper wire. Then, the bottom drive motor 603 can be easily started, causing the drive gear 601 to rotate, which in turn rotates the driven gear 602, causing the screw 401 to rotate accordingly. Since the sliding block 301 is rotatably connected to the screw 401, the rotation of the screw 401 easily moves the sliding block 301 up and down, thus moving the top plate 3 to the top, which in turn moves the top pressing plate 302 to the top. The movement of the copper wire, which is fixed by the clamping plate 202, allows the pull rod 201 to be pulled. The change in tension can be monitored by the tension gauge 2, thus enabling the tensile test of the alloy copper wire. During use, the protective cover 5 can be easily rotated to place the copper wire between the protective covers 5, which can easily block the copper wire and prevent accidental splashing when it breaks. At the same time, the top of the protective cover 5 is slidably connected to the adjusting cover 501. The adjusting cover 501 can be easily adjusted by opening and closing the protective cover 5. Since the top of the adjusting cover 501 is rotatably connected to the top plate 3, the adjusting cover 501 can be easily moved along with the top plate 3 as it moves upward. This ensures that the copper wire is always inside the protective cover 5 and the adjusting cover 501, making it safer.

[0023] During use, the rotating bolt 203 can be easily rotated to bring the clamping plate 202 closer, thus facilitating the clamping of copper wires of different sizes. The protective cover 5 and adjusting cover 501 can also be easily rotated to place the copper wire between them. Since the top plate 3 has a receiving groove on one side, rotating the pressing plate 302 to either side of the groove allows for easy placement of the copper wire inside. Rotating the screw 303 then brings the pressing plate 302 closer to clamp the copper wire. The position of the mounting post 304 can also be moved to adjust the position of the screw 303, thereby adjusting the position of the pressing plate 302, ensuring it is offset from the receiving groove to prevent the copper wire from slipping out during pulling. After testing, rotating the pressing plate 302 to either side of the receiving groove releases its clamping mechanism, allowing the copper wire to be easily removed from the groove for replacement with a new wire for testing – a very convenient process.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
