Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, specifically a tensile testing table for high-speed steel tensile testing. Background Technology

[0002] Utility model patent with publication number CN211856122U discloses a tensile testing table for high-speed steel, including a table surface, a threaded cap, a steel rod, and a semi-circular block. A support base is welded to the lower surface of the table surface, and a fixed limiting block is welded to one side of the upper surface of the table surface. A movable limiting block is slidably installed on the other side of the upper surface of the table surface. Grooves are formed on the upper surfaces of both the movable and fixed limiting blocks. Obstruction blocks are symmetrically cast at both ends of the steel rod. The obstruction blocks are slidably installed between the two semi-circular blocks, and a threaded cap is threaded between the two semi-circular blocks. The semi-circular blocks are located in the grooves.

[0003] The above-mentioned patents have the following shortcomings: Two semicircular blocks are snapped onto one end of the steel, so that the blocking block on the steel is located in the circular cavity formed by the annular grooves on the two semicircular blocks. Then, the threaded cap is rotated and installed on the two semicircular blocks to complete the installation. During the tensile test, the fixing force clamped on both sides of the high-speed steel is definitely less than the strength of the high-speed steel itself. Therefore, the high-speed steel will slip off before it deforms or breaks, thus making it impossible to test effectively. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a tensile testing table for high-speed steel tensile testing, which solves the problem in the above-mentioned patent where two semicircular blocks are clamped to one end of the steel, so that the resistance block on the steel is located in the circular cavity formed by the annular grooves on the two semicircular blocks, and then the threaded cap is rotated and installed on the two semicircular blocks to complete the installation operation. However, during the tensile test, the fixing force clamped on both sides of the high-speed steel is definitely less than the strength of the high-speed steel itself.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0018] This utility model provides a tensile testing table for high-speed steel tensile testing. Please refer to [link / reference]. Figure 1-3 It includes a bottom support plate 1, with a left docking mechanism and a right docking mechanism respectively set at the left and right ends of the bottom support plate 1. A tensioning mechanism is connected to the left side of the left docking mechanism. Both the left and right docking mechanisms have bending functions, which can be used to bend the two ends of the high-speed steel being tested.

[0019] The right docking mechanism includes a first support shaft 7 that is rotatably connected to the bottom support plate 1, a first rotating disk 4 that is fixedly mounted on the first support shaft 7, and a first bent pin 8 that is welded onto the first rotating disk 4.

[0020] A bearing seat 19 is fixedly installed on the bottom support plate 1. The bearing seat 19 is rotatably connected to the first support shaft 7 through a bearing. A brake ring 191 is welded on the bearing seat 19. The brake ring 191 and the first support shaft 7 are fixed together by bolts.

[0021] A first mounting sleeve 5 is welded onto the first rotating disk 4. A first drive rod 6 is inserted into the inner wall of the first mounting sleeve 5. The first mounting sleeve 5 and the first drive rod 6 are fixed together by bolts. A first U-shaped plate 3 is sleeved on the first support shaft 7, and a first support upright plate 2 is welded to the right end of the first U-shaped plate 3. The first support upright plate 2 is welded to the bottom support plate 1.

[0022] The left docking mechanism includes a second support shaft 13 rotatably connected to the bottom support plate 1. A second rotating disk 10 is fixedly mounted on the second support shaft 13. A second bent pin 14 is welded to the second rotating disk 10. The bottom end of the second rotating disk 10 is rotatably connected to a bearing seat 19 via a bearing. The bearing seat 19 at the bottom of the second rotating disk 10 is mounted on a moving block 20. The moving block 20 is slidably connected to the sliding groove at the top of the bottom support plate 1. A second U-shaped plate 9 is sleeved on the second support shaft 13. A first mounting plate 18 is welded to the end of the second U-shaped plate 9. The first mounting plate 18 is bolted to a second mounting disk 17. The second mounting disk 17 is welded to the end of the telescopic rod 161 of the hydraulic cylinder 16. The hydraulic cylinder 16 is mounted on a second support plate 15, which is welded to the bottom support plate 1. The hydraulic control system controls the operation of the hydraulic cylinder 16.

[0023] A second mounting sleeve 11 is welded onto the second rotating disk 10. A second drive rod 12 is inserted into the inner wall of the second mounting sleeve 11, and the second mounting sleeve 11 and the second drive rod 12 are fixed together by bolts.

[0024] In practical use, the two ends of the high-speed steel rod are positioned between the second support shaft 13 and the second bending pin 14, and between the first support shaft 7 and the first bending pin, respectively. The bolts fixing the second support shaft 13 and the brake ring 191 are removed, and the bolts fixing the first support shaft 7 and the brake ring 191 are also removed. By holding the second drive rod 12 and the first drive rod 6, the second rotating disk 10 and the first rotating disk 4 are rotated 180 degrees, respectively, so that the two ends of the high-speed steel rod are bent into a U-shape. The two ends of the high-speed steel rod are then fixed with a wire rope lock. The second support shaft 13 and the brake ring 191 are then fixed with bolts, and the first support shaft 7 and the brake ring 191 are then fixed with bolts. The telescopic rod 161 retracts, causing the second U-shaped plate 9 to move, thereby stretching the left end of the high-speed steel rod. Example 2

[0025] See attached document Figure 4 Unlike Embodiment 1, the inner walls of the first mounting sleeve 5 and the second mounting sleeve 11 are both connected to telescopic drive rods and fixed to the telescopic drive rods by bolts. The telescopic drive rod includes a bolt rod 21, and an internal threaded tube 22 is threaded onto the bolt rod 21. At this time, the length of the telescopic drive rod can be adjusted. The longer the telescopic drive rod is adjusted, the more effort can be made to bend the two ends of the high-speed steel rod.
