Description

Technical Field

[0001] This utility model relates to the field of metal detection technology, specifically to a metal processing tensile strength testing fixture. Background Technology

[0002] Tensile strength testing of metals is a standardized mechanical test used to determine the performance indicators of metallic materials under uniaxial tensile load. During the test, a standard specimen is placed on a universal testing machine, and an axial tensile force is applied at a constant rate until the specimen breaks. The load-displacement curve is recorded in real time by sensors, allowing calculation of tensile strength (the material's ability to resist maximum uniform plastic deformation), yield strength (the stress at which significant plastic deformation occurs), elongation after fracture, and reduction of area (reflecting the material's ductility). The testing fixture is a crucial component for fixing metal samples during tensile testing. Traditional metal tensile testing fixtures are often specifically designed for metal bars. When testing metal wires, the fixture's clamping position is prone to deformation, causing the wire sample to break at the clamping point, resulting in inaccurate test data. Utility Model Content

[0003] The purpose of this utility model is to provide a metal processing tensile strength testing fixture to solve the problem mentioned in the background art that traditional metal tensile strength testing fixtures are mostly special fixtures for metal bars.

[0005] Preferably, a groove is provided between the clamping seat and the adjusting seat, the clamping protective block is spliced ​​to the side of the groove near the clamping seat through a limiting groove, the clamping adjusting block is slidably connected to the side of the groove near the adjusting seat, and the clamping adjusting block cooperates with the clamping groove provided on the clamping protective block through a wedge structure.

[0006] Preferably, the clamping adjustment block has a rotation limiting groove inside, the inner end of the adjustment component is rotatably connected to the rotation limiting groove after being spliced, and the outer side of the adjustment component has a rotation handle.

[0007] Preferably, the front surface of the clamping seat is connected to a limiting block by bolts, and the limiting block is spliced ​​with the clamping protection block.

[0013] Please see Figure 1-5This utility model provides a metal processing tensile strength testing fixture, including a back plate 1. The lower end of the front surface of the back plate 1 is provided with a clamping seat 2. The upper end of the clamping seat 2 has an arc-shaped structure. The upper surface of the clamping seat 2 has an arc-shaped structure with a clamping groove 3. An adjusting seat 4 is provided on one side of the clamping seat 2. The adjusting seat 4 and the clamping seat 2 are integrally formed. The inside of the clamping seat 2 is provided with a clamping protective block 5 near the adjusting seat 4. The side wall of the clamping protective block 5 also has a clamping groove 3. The inside of the adjusting seat 4 is provided with a clamping adjusting block 6 at a position corresponding to the clamping protective block 5. An adjusting component 7 is threadedly connected to the outside of the adjusting seat 4. The inner end of the adjusting component 7 is connected to the adjusting clamping block 6. A mounting seat 8 is provided at the upper end of the front surface of the back plate 1 at a position corresponding to the clamping groove 3.

[0014] In use, the overall testing fixture structure is installed on the tensile testing equipment via the mounting base 8. The overall structure is integrated onto the back plate 1 to ensure the strength of the overall structure. The metal wire to be tested is inserted into the adjusting base 4 and extends out of the adjusting base 4 after passing around the arc-shaped structure of the clamping base 2 along the clamping groove 3. The metal wire is placed between the clamping protective block 5 and the clamping adjusting block 6. The clamping adjusting block 6 is moved towards the clamping protective block 5 by rotating the adjusting component 7. The metal wire is clamped by the wedge-shaped clamping adjusting block 6 and the clamping groove 3 of the clamping protective block 5, which ensures the clamping strength while reducing the additional pressure on the metal wire. During installation, the two testing fixture structures need to be installed on the upper and lower mounting bases of the tensile testing equipment respectively. The two testing fixtures clamp and fix the two ends of the metal wire to perform the tensile testing operation.

[0015] A groove 9 is provided between the clamping base 2 and the adjusting base 4. The clamping protective block 5 is connected to the side of the groove 9 near the clamping base 2 via a limiting groove 10. The clamping adjusting block 6 is slidably connected to the side of the groove 9 near the adjusting base 4. The clamping adjusting block 6 cooperates with the clamping groove 3 provided on the clamping protective block 5 through a wedge structure. By providing the groove 9, the clamping protective block 5 and the clamping adjusting block 6 are housed, thereby ensuring the installation requirements of the clamping protective block 5 and the clamping adjusting block 6 and ensuring the clamping strength of the clamping protective block 5 and the clamping adjusting block 6.

[0016] The clamping adjustment block 6 has a rotation limiting groove 11 inside. The inner end of the adjustment component 7 is inserted into the rotation limiting groove 11 and rotated. The outer side of the adjustment component 7 is provided with a rotating handle 12. The adjustment component 7 and the clamping adjustment block 6 are rotatedly connected through the rotation limiting groove 11. When it is necessary to clamp the metal wire, rotating the rotating handle 12 can drive the clamping adjustment block 6 to move, thereby clamping and fixing the metal wire through the clamping protection block 5 and the clamping adjustment block 6.

[0017] The front surface of the clamping seat 2 is connected to a limiting block 13 by bolts. The limiting block 13 is spliced ​​with the clamping protection block 5 to improve the connection strength between the clamping protection block 5 and the clamping seat 2.
