Description

Technical Field

[0001] This utility model relates to the field of steel strength testing technology, specifically a steel strength testing device. Background Technology

[0002] The ability of a material to resist failure under external forces is called the material's strength. When a material is subjected to external forces, stress is generated within it. As the external force increases, the stress increases accordingly until the bonding force between the material's particles is insufficient to resist the applied external force, at which point the material fails. The limiting value of stress reached at which the material fails is called the material's ultimate strength, commonly denoted by f. The unit of material strength is megapascals (MPa).

[0003] Currently, some existing steel strength testing devices generally use a hydraulic device to push a pressure block to apply pressure to the steel to test its strength. However, the pressure block is usually fixed at the bottom of the hydraulic device. When it is necessary to replace the pressure block according to the different shapes of the steel, it is relatively inconvenient to replace the pressure block and use it. Utility Model Content

The auxiliary support plates are slidably connected to the interior of the housing 1 via sliders. When the support frame 5 moves, it will drive... The fixed auxiliary support plates move simultaneously. A drive motor 4 is fixed to the surface of the device housing 1.

The surface of the bidirectional threaded rod 10 has two sets of threads in opposite directions. The bidirectional threaded rod 10 passes through the bottom of the support frame 5 and is threadedly connected to the support frame 5. When the bidirectional threaded rod 10 rotates, it will drive the threaded support frame 5 to move. The bidirectional threaded rod 10 passes through the bottom of two sets of support frames 5 and is threadedly connected to them. When the bidirectional threaded rod 10 rotates, it will drive the two sets of threaded support frames 5 to move towards each other, thereby adjusting the distance between the two sets of support frames 5, so that it can adapt to steel of different sizes and improve the device's adaptability to different materials. The adaptability of steel of the same size, the second hydraulic rod 6 fixed to the top of the support frame 5, two sets of the second hydraulic rod 6 are symmetrically fixed to the top of a set of support frames 5, the pressure plate 7 fixed to the top of the output shaft of the second hydraulic rod 6, the second hydraulic rod 6 can push the pressure plate 7 fixed to the top of the output shaft to move, by placing the steel between the two sets of support frames 5 and placing it at the bottom of the pressure plate 7, and pushing the pressure plate 7 by the second hydraulic rod 6, the steel can be clamped and fixed by the pressure plate 7, so that it is fixed between the two sets of support frames 5, the first hydraulic rod 3 fixed to the top of the device housing 1, the fixing plate 8 fixed to the top of the output shaft of the first hydraulic rod 3, the first hydraulic rod 3 can push the fixing plate 8 fixed to the top of the output shaft to move, the pressure block 9 is inserted into the bottom of the fixing plate 8, when the fixing plate 8 moves, it will The bottom insert pressure block 9 moves, the guide plate 11 is inserted into the fixed plate 8, and the guide groove 18 is formed on the surface of the guide plate 11. Several sets of guide grooves 18 are formed on the surface of the guide plate 11. The fixing rod 12 is fixed to the surface of the guide plate 11. Two sets of fixing rods 12 are symmetrically fixed on the surface of one set of guide plates 11. When the fixing rod 12 moves, it will drive the fixed guide plate 11 to move. The first spring 13 is sleeved on the surface of the fixing rod 12. One end of the first spring 13 contacts the surface of the guide plate 11, and the other end contacts the inner surface of the fixed plate 8. When the guide plate 11 moves, it will squeeze the first spring 13 and cause the first spring 13 to deform. When there is no external force interference, the first spring 13 will push the guide plate 11 to move. The limiting component is set inside the fixed plate 8.The position of the pressure block 9 can be restricted, and the number of limiting components is the same as the number of guide grooves 18.

[0020] The limiting assembly includes a limiting post 17 inserted inside the pressure block 9. The top end of the limiting post 17 is inserted inside the pressure block 9, and the bottom end is inserted inside the fixing plate 8. When the limiting post 17 is inserted inside the pressure block 9, it can limit the position of the pressure block 9 and prevent the pressure block 9 from detaching from one side of the fixing plate 8. A limiting plate 15 is fixed to the bottom of the limiting post 17. When the limiting plate 15 moves, it will drive the fixed limiting post 17 to move. The limiting plate 15 can limit the position of the limiting post 17 and prevent the limiting post 17 from detaching from the fixing plate 8.

When the limiting plate 15 moves, it will squeeze the second spring 16 and cause the second spring 16 to deform. When there is no external force interference, the second spring 16 will push the limiting plate 15 to move. At the same time, the second spring 16 can push the limiting plate 15 and apply a certain pressure to the limiting plate 15, so that the limiting plate 15 drives the guide post 14 to move and make it stick tightly to the surface of the guide groove 18.

[0021] Working principle: When the strength of steel needs to be tested, the steel is placed between two sets of support frames 5 and positioned on the bottom side of the pressure plate 7. At this time, the pressure plate 7 can be moved by the second hydraulic rod 6, and the steel is clamped and fixed by the pressure plate 7. After the steel is fixed, the fixing plate 8 is pushed by the first hydraulic rod 3, which causes the fixing plate 8 to move the pressure block 9 closer to the steel and apply pressure to the surface of the steel, thereby testing the strength of the steel. When the strength of steel of different shapes needs to be tested and the pressure block 9 needs to be replaced, the fixing rod 12 is pulled, which causes the fixing rod 12 to move the guide plate 1. When the guide plate 11 moves, it will drive the guide groove 18 on the surface to move, thereby causing the guide post 14 to move along the surface of the guide groove 18. This causes the guide post 14 to move towards the inside of the guide plate 11 and drive the limiting plate 15 and the limiting post 17 to move. At this time, the limiting post 17 will move towards the side closer to the guide plate 11 and disengage from the inside of the pressure block 9, so that the limiting post 17 no longer restricts the position of the pressure block 9. At this time, the pressure block 9 can be moved directly towards the side of the fixing plate 8 to remove the pressure block 9 from the bottom side of the fixing plate 8. Replacing the pressure block 9 is relatively convenient and easy to use.
