[0002] Cold-formed angle steel can be divided into different types, such as L-shaped angle steel, inwardly rolled angle steel, Z-shaped angle steel, etc. It can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, container racks and warehouse shelves, etc.

[0003] Currently, after the production of inward-curled angle steel, samples need to be taken for strength testing. However, existing strength testing devices have several problems. The positioning structure of the existing testing equipment, by squeezing the two ends of the sample for tightening, cannot comprehensively restrict the sample's position, leading to displacement or flipping during testing, thus affecting the test results. Furthermore, the positioning mechanism cannot be adjusted according to the user's needs, making it impossible to understand the pressure values ​​on the outer side of the sample under different restrictive conditions. Therefore, we propose a testing device for duplex stainless steel cold-bent angle steel to solve these problems. Summary of the Invention

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, a testing device for duplex stainless steel cold-bent edge-rolled angle steel includes an operating table 1. A protective mechanism 2 is provided above the operating table 1. An inwardly rolled edge angle steel 3 is provided inside the protective mechanism 2. The outer side of the inwardly rolled edge angle steel 3 abuts against a base plate 4. The base plate 4 is fixedly installed on the surface of the operating table 1. The outer side of the inwardly rolled edge angle steel 3 abuts against a positioning plate 5. A connecting plate 6 is fixedly installed on the outer side of the positioning plate 5. A bolt 7 is inserted into the connecting plate 6. The bottom end of the bolt 7 engages with a threaded hole 8. The threaded hole 8 is opened on the surface of the operating table 1. A T-shaped block 9 is fixedly installed at the bottom of the positioning plate 5. The T-shaped block 9 is inserted into a T-slot 10. The T-slot 10 is opened on the operating table 1. On the surface of the platform 1, a groove 11 is provided on the outer side of the positioning plate 5, and a reinforcing plate 12 is inserted into the groove 11. The positioning plate 5 and the reinforcing plate 12 are rotatably connected by a connecting shaft 13. A bolt 2 14 is inserted into the reinforcing plate 12, and the bottom end of the bolt 2 14 engages with the inside of a threaded hole 2 15. The threaded hole 2 15 is located on the surface of the platform 1. The outer side of the inwardly rolled angle steel 3 abuts against a pressure plate 16. A pressure sensor 17 is fixedly installed on the outer side of the pressure plate 16. The pressure sensor 17 is fixedly installed at the hydraulic end of a hydraulic cylinder 18. The hydraulic cylinder 18 is located on the surface of the platform 1. Threaded holes 1 8 and 15 are respectively provided on the surface of the platform 1. As the operator places the inwardly rolled angle steel 3 onto the platform... On the surface of the operating table 1, the inwardly rolled angle steel 3 abuts against the outer side of the base plate 4 and the positioning plate 5. Personnel can push the positioning plate 5 according to their needs. During this process, the T-block 9 slides inside the T-slot 10. Then, through the action of the connecting shaft 13, personnel can flip the reinforcing plate 12, causing it to abut against the outer side of the inwardly rolled angle steel 3 and the surface of the operating table 1. Subsequently, bolt 7 engages with threaded hole 8, and bolt 14 engages with threaded hole 15, thereby securing the position of the inwardly rolled angle steel 3. This structure also facilitates the replacement of the inwardly rolled angle steel 3. All bolts 7, threaded holes 8, 14, and 15 are configured with the same fine-pitch thread. The use of fine-pitch threads provides self-locking properties, thereby improving the stability of the connection. The outer side of the reinforcing plate 12 abuts against the outer side of the inwardly rolled angle steel 3 and the surface of the operating table 1, effectively securing the position of the inwardly rolled angle steel 3. The connecting plate 6 abuts against the surface of the operating table 1. The outer side of the T-block 9 abuts against the inner wall of the T-slot 10. The T-block 9 can slide inside the T-slot 10, facilitating the pushing of the positioning plate 5 by personnel. Square grooves 19 are provided on the outer sides of both the groove 11 and the reinforcing plate 12. Magnetic sheets 20 are fixedly installed inside the square grooves 19. The magnetic sheets 20 enable the reinforcing plate 12 to be positioned when it is flipped outward.

[0022] like Figure 1 and Figure 2 As shown, the protective mechanism 2 includes a hinge seat 21, which is fixedly mounted on the surface of the operating table 1. A sleeve shaft 22 is sleeved on the outer side of the hinge seat 21, and the sleeve shaft 22 is fixedly mounted on the outer side of the square cover 23. The square cover 23 covers the upper part of the inwardly rolled angle steel 3. A magnetic block 24 is fixedly mounted on the top of the square cover 23. The square cover 23 is made of acrylic sheet, and a handle 25 is fixedly mounted on the top of the square cover 23. By setting up the protective mechanism 2, after the personnel have tightened the position of the inwardly rolled angle steel 3, during the strength test, the square cover 23 can cover the upper part of the inwardly rolled angle steel 3 to prevent the debris generated by the breakage of the inwardly rolled angle steel 3 during the test from flying outward and causing injury to the personnel.

[0023] This utility model provides a testing device for duplex stainless steel cold-bent edge-rolled angle steel, the specific working principle of which is as follows:

[0024] During use, the operator places the inwardly rolled angle steel 3 on the surface of the operating table 1 and then pushes it so that it abuts against the outer side of the base plate 4 and the positioning plate 5. The cooperation between the base plate 4 and the positioning plate 5 restricts both ends and one side of the inwardly rolled angle steel 3. At this time, the bottom end of bolt 7 abuts against the surface of the operating table 1. The operator then pushes the positioning plate 5 according to their needs, allowing it to move laterally on the outer side of the inwardly rolled angle steel 3 and the operating table 1. This adjusts the lateral position of the positioning plate 5, allowing for testing of the pressure values ​​on the outer side of the inwardly rolled angle steel 3 under different tightened positions. During the lateral movement of the positioning plate 5, the T-block 9 can... The internal sliding of the groove 10, along with the movement of the positioning plate 5, can respectively drive the movement of the connecting plate 6, bolt 7, and reinforcing plate 12. When the positioning plate 5 is pushed, a portion of the bottom end of bolt 7 can slide into the threaded hole 8, thereby positioning the positioning plate 5. Then, the operator can rotate bolt 7 with a wrench, so that bolt 7 can engage with the threaded hole 8, thus fastening the connecting plate 6 and the positioning plate 5 to the surface of the operating table 1. With square grooves 19 on the outer sides of both the positioning plate 5 and the reinforcing plate 12, and with magnetic pieces 20 inside the square grooves 19, the reinforcing plate 12 can be restricted to one side above the positioning plate 5. The operator moves the reinforcing plate 12 outward, at which point the magnetic pieces 20 separate, the reinforcing plate 12 can rotate outside the connecting shaft 13 and in the groove 11, and then one side of the reinforcing plate 12 abuts against the surface of the operating table 1. During this time, the reinforcing plate 12 can abut against the outer side of the inwardly rolled angle steel 3. Then, the operator rotates the bolt 14 with a wrench, so that the bolt 14 can engage with the reinforcing plate 12 and the threaded hole 15. Thus, the reinforcing plate 12 can be fastened to the surface of the operating table 1 and the outer side of the inwardly rolled angle steel 3, so that the positioning plate 5 and the reinforcing plate 12 are in a front-to-back clamping shape to fasten the position of the inwardly rolled angle steel 3. Then, the hydraulic cylinder 18 is activated, so that the hydraulic rod on the hydraulic cylinder 18 can drive the pressure sensor 17 to move. This allows the pressure plate 16 to abut against the outer side of the inwardly rolled angle steel 3. Then, the operator holds the outside of the handle 25 and flips the square cover 23 so that it covers the top of the inwardly rolled angle steel 3. During this process, the sleeve 22 slides outside the hinge seat 21. Then, under the action of the magnetic block 24, the square covers 23 are tightly connected. Then, with the continuous operation of the hydraulic cylinder 18, the pressure sensor 17 drives the pressure plate 16 to move, allowing the pressure plate 16 to test the strength of the inwardly rolled angle steel 3. As the square cover 23 covers the inwardly rolled angle steel 3, during the test, the inwardly rolled angle steel 3 will be continuously bent and deformed, resulting in localized cracking of the rolled angle steel 3 to some extent.Therefore, when debris is generated during cracking and flies outwards, the square cover 23 effectively prevents the debris from flying outwards and thus helps to gather it together.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
