[0001] This utility model relates to the field of alloy processing technology, specifically to a tooling for alloy tensile testing. Background Technology
[0002] Alloys are substances with metallic properties synthesized by mixing and melting two or more metals or non-metals, followed by cooling and solidification. Tensile testing is a test method for determining the properties of materials under axial tensile load. Data obtained from tensile testing can determine the material's elastic limit, elongation, elastic modulus, proportional limit, reduction of area, tensile strength, yield point, yield strength, and other tensile performance indicators. Currently, when performing tensile tests on existing rod-shaped alloys, the rod-shaped alloys need to be clamped. The tensile force during stretching is relatively large, and the rod-shaped alloys are prone to displacement during the stretching process, which affects the accuracy of the tensile test data. Utility Model Content

[0009] Beneficial effects
[0010] The tooling for alloy tensile testing provided by this utility model has the following beneficial effects:
[0011] This design uses a drive motor to rotate, which in turn rotates the first connecting rod, controlling the rotation of the first bevel gear, which in turn rotates the second bevel gear, controlling the rotation of the second connecting rod, which in turn rotates the lead screw. This causes the moving chamber to move, which in turn moves the fixed chamber, causing the clamping block to press against the alloy rod body to fix it in place.

This design can prevent the alloy rod body from shifting due to excessive tensile force during stretching, thereby improving the accuracy of the tensile test data. Attached Figure Description

Three pairs of clamping blocks 24 are movably arranged in a circular shape on the fixing block 31. Anti-slip blocks 19 are provided on the clamping blocks 24.
[0021] The drive motor 3 rotates, causing the first connecting rod 20 to rotate, controlling the first bevel gear 23 to rotate, which in turn drives the second bevel gear 22 to rotate, controlling the second connecting rod 21 to rotate, causing the lead screw 5 to rotate. The moving chamber 11 is movably installed in the guide groove 30 via the guide post 6. The lead screw 5 is screwed into the moving chamber 11, causing the moving chamber 11 to move, which in turn drives the fixed chamber 1 to move. The fixed chamber 1 squeezes the clamping block 24, causing the clamping block 24 to squeeze the alloy rod body 4, which is used to fix the alloy rod body 4. As the fixed chamber 1 moves, the tension on the alloy rod body 4 increases, and at the same time, the pressure of the clamping block 24 on the alloy rod body 4 increases. This can prevent the alloy rod body 4 from shifting due to the large tension during stretching, thereby improving the accuracy of the tensile test data.
[0022] Anti-slip block 19 is a rubber anti-slip block, which plays a role in preventing slippage and can prevent the alloy rod body 4 from coming off the clamping block 24 during the stretching process.
[0023] In this embodiment, the measuring mechanism includes a slider 12, a slide groove 9 is provided on the worktable 10, the slider 12 is slidably installed in the slide groove 9, a first multi-stage manual telescopic rod 13 is provided on the upper wall of the slider 12, a first support block 14 is rotatably provided on the telescopic end of the first multi-stage manual telescopic rod 13, a second multi-stage manual telescopic rod 15 is provided on the first support block 14, a second support block 16 is provided on the telescopic end of the second multi-stage manual telescopic rod 15, a third multi-stage manual telescopic rod 17 is provided on the second support block 16, and a measuring ruler 18 is provided on the third multi-stage manual telescopic rod 17.

[0026] The first heating chamber 2 is inserted into the slot 27 via the insert block 26, so that the first heating chamber 2 is installed on the second heating chamber 25. The insert installation method can facilitate the installation of the first heating chamber 2 by the staff, reduce the installation time of the first heating chamber 2, and thus improve the efficiency of the tensile test.
[0027] The arc-shaped heating plate 28 can heat the alloy rod body 4, making it convenient for staff to test the tensile test data of the alloy rod body 4 at different temperatures.
[0028] In this embodiment, a pair of limiting blocks 7 are provided on the workbench 10, and the slider 12 is movably disposed on the limiting blocks 7;
[0029] The limit block 7 is used to restrict the movement of the slider 12 and prevent the measuring mechanism from disengaging from the slide groove 9, thus providing protection.
[0030] Example: When the tooling is in use, the drive motor 3 rotates, causing the first connecting rod 20 to rotate, controlling the first bevel gear 23 to rotate, which in turn drives the second bevel gear 22 to rotate, controlling the second connecting rod 21 to rotate, causing the lead screw 5 to rotate. The moving chamber 11 is movably installed in the guide groove 30 via the guide post 6. The lead screw 5 is screwed into the moving chamber 11, causing the moving chamber 11 to move, which in turn moves the fixed chamber 1. The fixed chamber 1 presses against the clamping block 24, causing the clamping block 24 to press against the alloy rod body 4, thus fixing the alloy rod body 4.

The first heating chamber 2 is inserted into the slot 27 through the insert block 26, so that the first heating chamber 2 is installed on the second heating chamber 25. The insert installation method can facilitate the operator's installation of the first heating chamber 2, reduce the installation time of the first heating chamber 2, and thus improve the efficiency of the tensile test. The arc-shaped heating plate 28 can heat the alloy rod body 4, which is convenient for the operator to detect the tensile test data of the alloy rod body 4 at different temperatures.
