[0002] In the stainless steel production process, performance testing is a key step to ensure that the quality and performance of stainless steel products meet the standards. Performance testing devices based on stainless steel material production are usually used to evaluate and test the mechanical properties and corrosion resistance of stainless steel and its products. Commonly used equipment includes tensile testing machines, hardness testing machines, impact testing machines, etc.

[0003] A stainless steel pipe bending performance detection device is disclosed in the patent publication number CN215931550U, which includes a base, a rotating shaft, a handle, a first gear, a second gear, a support block, a rack, a lifting plate, a scale, etc. The base is rotatably provided with a rotating shaft, and one side of the rotating shaft is rotatably connected to the handle. The lifting plate is adjusted up and down by rotating the handle, which is convenient for adjusting the bending scale of the steel pipe. By starting the driving cylinder, the output shaft of the cylinder drives the first pressure block to bend the steel pipe. There is no need to manually bend the steel pipe by using a hydraulic jack, which provides convenience to people to a certain extent.

[0004] The prior art has the following defects: It is impossible to perform multiple performance tests on the same stainless steel sample: Stainless steel materials usually need to be tested for multiple properties, the most common of which are tensile testing, bending testing, and hardness testing. However, it is impossible to perform multiple performance tests on the same stainless steel sample. The same sample needs to be sent to different equipment for testing, resulting in a lengthy and inefficient testing process. In addition, it is necessary to purchase a variety of different testing equipment, which increases the initial investment and subsequent maintenance costs. Therefore, it is necessary to integrate multiple performance testing devices to reduce costs and improve efficiency.

[0005] Unable to adapt to the testing of stainless steel specimens of different shapes: Stainless steel materials are usually processed into various shapes to meet different industrial and commercial needs. Common ones are plates, pipes and bars. However, devices that cannot adapt to the testing of stainless steel specimens of different shapes will lead to inaccurate tensile, bending and hardness test results, which in turn affects the correct evaluation of material properties and overall quality control. Therefore, it is necessary to set up a clamping device that can clamp stainless steel specimens of different shapes and a pressure device at the bottom to make the tensile, bending and hardness test results more accurate. Summary of the invention

The arc clamping block 334 is arc-shaped in the middle and flat at both ends, which can adapt to round tubes and round rods of different diameters and square tube sheets of different sizes. The two-way threaded rod 343 is rotated by turning any second hand wheel 341. Since the two horizontal moving blocks 345 are respectively threadedly connected with the left-handed thread groove 342 and the right-handed thread groove 344 on the two-way threaded rod 343, the two flat clamping blocks 346 are in two Driven by the lateral moving block 345, the stainless steel sample 6 is clamped and fixed by moving in opposite directions, which can adapt to stainless steel samples 6 of different diameters and widths. Then, the third hand wheel 45 is rotated to drive the driving gear 47 to rotate through the driving rod 46. The driving gear 47 is meshed with the vertical rack 43 in the lifting column 42, so that the lifting column 42 slides upward in the lifting groove 44, pushing the arc-shaped force block 41 to contact and support the bottom of the stainless steel sample 6.

[0045] By rotating the first hand wheel 331 to drive the one-way threaded rod 332 to rotate, the arc clamping block 334 is driven by the vertical moving block 333 to move downward to clamp and fix the stainless steel sample 6. The arc clamping block 334 is arc-shaped in the middle and flat at both ends, which can adapt to round tubes and round bars of different diameters and square tube sheets of different sizes.

[0046] By turning any one of the second hand wheels 341 to drive the bidirectional threaded rod 343 to rotate, since the two lateral moving blocks 345 are respectively threadedly connected to the left-handed thread groove 342 and the right-handed thread groove 344 on the bidirectional threaded rod 343, the two flat clamping blocks 346 are driven by the two lateral moving blocks 345 to move toward each other to clamp and fix the stainless steel sample 6, which can adapt to stainless steel samples 6 of different diameters and widths.

[0047] Then, the third hand wheel 45 is rotated to drive the driving gear 47 to rotate through the driving rod 46. The driving gear 47 is meshed with the vertical rack 43 in the lifting column 42, so that the lifting column 42 slides upward in the lifting groove 44, pushing the arc-shaped force block 41 to contact and support the bottom of the stainless steel sample 6. The surface of the arc-shaped force block 41 is the same as the surface of the arc-shaped clamping block 334.

[0048] During hardness testing, the force-bearing surface of the hardness testing needle must be supported; when performing hardness testing on round tubes and round rods, the arc in the middle of the arc-shaped force-bearing block 41 contacts and supports the bottom of the round tube and round rod, and then the hardness tester 53 is used to test it; when performing hardness testing on square tube sheets, the push block 48 can be moved back and forth in the limit groove 49 so that the flat shapes at both ends of the arc-shaped force-bearing block 41 contact and support the bottom of the square tube sheet, and then the hardness tester 53 is used to test it.

[0049] During the bending test, the arc-shaped force block 41 is moved down a certain distance to wait for the stainless steel sample 6 to be bent under pressure, so as to quantify the bending degree. Then, the stainless steel sample 6 in the clamping and fixing groove 35 is moved to the bending swing groove 36, and then the stainless steel sample 6 is tested using the bending detector 54.

[0050] During the tensile test, the stainless steel sample 6 is clamped more deeply using the clamping fixing groove 35 to prevent the stainless steel sample 6 from falling off during the tensile process, and then the two clamping shells 32 are pulled in opposite directions on the transverse sliding rod 31 to achieve the purpose of tensile testing.
