Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a bending device for easy positioning in building materials strength testing. Background Technology

[0002] In the production and quality control of building materials, material strength testing is a crucial step. This is especially true for building materials such as steel plates, which require bending to test strength; the accuracy and stability of the bending process directly affect the reliability of the test results.

[0003] Existing bending devices for testing the strength of building materials cannot ensure that the building materials are in an accurate initial position before bending. When testing the bending of steel plates, if right-angle positioning cannot be achieved, the consistency of each bending operation cannot be guaranteed, and the strength performance of the material cannot be truly reflected. Therefore, we have introduced a new bending device for testing the strength of building materials that is easy to position. Utility Model Content

[0004] The main objective of this invention is to provide a conveniently positioned bending device for testing the strength of building materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A conveniently positioned bending device for testing the strength of building materials includes a base. A positioning mechanism is fixedly connected to the upper left side of the base. Support plates are fixedly connected to the front right side and the rear right side of the upper right side of the base. A connecting top plate is fixedly connected to the upper end of the two support plates. A hydraulic cylinder is fixedly installed in the middle of the upper end of the connecting top plate. A pressure sensor is fixedly installed at the output end of the hydraulic cylinder. A bending plate is fixedly installed at the lower end of the pressure sensor. Stabilizing mechanisms are fixedly installed on the lower front and rear left and lower front and lower rear right sides of the base. Casters are fixedly installed at the four corners of the lower end of the base.

[0007] Preferably, the positioning mechanism includes a positioning seat, the upper end of which has a positioning groove, the upper left end of which has a sliding groove, the lower part of which has several threaded holes, three sliders slidably connected inside the sliding groove, each slider having a movable plate fixedly connected to its left end, each movable plate having a screw threadedly connected to its lower left end, each movable plate having an extension plate fixedly connected to its upper end, and each extension plate having a fixed rotating rod threadedly connected to its upper right end.

[0008] Preferably, the lower end of the positioning seat is fixedly connected to the base, and the inner angle of the positioning groove is a right angle.

[0009] By adopting the above technical solution, the upper left corner of the steel plate is in close contact with the inner corner of the positioning groove, which can achieve right-angle positioning of the steel plate and ensure the accuracy of the initial position of the steel plate.

[0010] Preferably, all three movable plates are located on the left side of the positioning seat, and the three screws are respectively threaded into the corresponding threaded holes.

[0011] By adopting the above technical solution: the slider on the right side of the moving plate allows the moving plate to slide back and forth, and the screw can be screwed into the corresponding threaded hole to fix the moving plate.

[0012] Preferably, the lower ends of the three extension plates do not contact the positioning seats, the three fixing rods are all located above the positioning grooves, and the lower ends of the three fixing rods are all fixedly connected to pads.

[0013] By adopting the above technical solution: by rotating the fixing rod, the pad at the bottom of the fixing rod is made to fit tightly against the upper part of the steel plate, thereby fixing the steel plate in the positioning groove.

[0014] Preferably, the stabilizing mechanism includes a connecting cylinder, an mounting block is fixedly connected to the right side of the outer surface of the connecting cylinder, a threaded rod is threadedly connected inside the connecting cylinder, a top block is fixedly connected to the upper end of the threaded rod, a throttle is fixedly connected to the lower end of the threaded rod, an anti-slip sleeve is fixedly connected to the outer surface of the throttle, and an anti-slip pad is fixedly connected to the lower end of the throttle.

[0015] Preferably, the right end of the mounting block is fixedly connected to the base, the upper part of the threaded rod extends to the top of the connecting cylinder, and the anti-slip pad is located below the connecting cylinder.

[0016] By adopting the above technical solution, the anti-slip pad moves downward to fit tightly against the ground, forming a stable limiting and fixing effect, preventing the device from shifting due to force during batch bending, and ensuring the safety and stability of operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By placing the steel plate to be bent in the positioning groove, and making the upper left corner of the steel plate fit tightly with the inner corner of the positioning groove, the steel plate can be positioned at a right angle, ensuring the initial position of the steel plate is accurate. Then, the sliding plate is moved back and forth by the slider to find a suitable fixing point and is connected to the corresponding threaded hole by the screw thread to fix the position of the moving plate. By rotating the fixing rod, the pad at the bottom of the fixing rod is made to fit tightly with the upper part of the steel plate, so that the steel plate can be fixed in the positioning groove and prevent the steel plate from shifting during the bending process.

[0019] 2. The casters at the bottom of the base enable flexible movement of the device, facilitating quick movement to the processing area for batch steel plates and reducing the workload of manual handling of steel plates. Once the device reaches the designated position, the anti-slip pad is moved downwards by rotating the handle, ensuring it is in close contact with the ground and forming a stable limiting and fixing effect. This prevents the device from shifting due to force during batch bending, ensuring the safety and stability of the operation. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A bending device for easy positioning in building material strength testing includes a base 1. A positioning mechanism 2 is fixedly connected to the upper left side of the base 1. Support plates 3 are fixedly connected to the upper right front side and upper right rear side of the base 1. A connecting top plate 4 is fixedly connected to the upper ends of the two support plates 3. A hydraulic cylinder 5 is fixedly installed in the middle of the upper end of the connecting top plate 4. A pressure sensor 6 is fixedly installed at the output end of the hydraulic cylinder 5. A bending plate 7 is fixedly installed at the lower end of the pressure sensor 6. A stabilizing mechanism 8 is fixedly installed on the lower front side and lower rear side of the left end, as well as the lower front side and lower rear side of the right end of the base 1. A moving wheel 9 is fixedly installed at the four corners of the lower end of the base 1.

[0030] In this embodiment, the positioning mechanism 2 includes a positioning seat 21. The upper end of the positioning seat 21 has a positioning groove 22. The upper left end of the positioning seat 21 has a sliding groove 23. The lower part of the sliding groove 23 has several threaded holes 24. Three sliders 25 are slidably connected inside the sliding groove 23. The left end of each of the three sliders 25 is fixedly connected to a movable plate 26. The lower left end of each of the three movable plates 26 is threaded with a screw 27. The upper end of each of the three movable plates 26 is fixedly connected to an extension plate 28. The upper right end of each of the three extension plates 28 is threaded with a fixing rod 29. The lower end of the positioning seat 21 is fixedly connected to the base 1. The inner angle of the positioning groove 22 is a right angle. The three movable plates 26 are all located on the left side of the positioning seat 21. The three screws 27 are threadedly connected to the corresponding threaded holes 24. The lower ends of the three extension plates 28 do not contact the positioning seat 21. The three fixing rods 29 are all located above the positioning groove 22, and the lower ends of the three fixing rods 29 are fixedly connected with a pad.

[0031] The above solution involves placing the steel plate to be bent into the positioning groove 22, ensuring that the upper left corner of the steel plate is in close contact with the inner corner of the positioning groove 22. This achieves right-angle positioning of the steel plate, ensuring accurate initial positioning. Then, the sliding plate 26 is moved back and forth by the slider 25 to find a suitable fixing point. The screw 27 is then threaded into the corresponding threaded hole 24 to fix the position of the sliding plate 26. By rotating the fixing rod 29, the pad at the bottom of the fixing rod 29 is brought into close contact with the upper part of the steel plate, thus fixing the steel plate in the positioning groove 22 and preventing displacement of the steel plate during bending.

[0032] In this embodiment, the stabilizing mechanism 8 includes a connecting cylinder 81. A mounting block 82 is fixedly connected to the right side of the outer surface of the connecting cylinder 81. A threaded rod 83 is threadedly connected inside the connecting cylinder 81. A top block 84 is fixedly connected to the upper end of the threaded rod 83. A handle 85 is fixedly connected to the lower end of the threaded rod 83. An anti-slip sleeve 86 is fixedly connected to the outer surface of the handle 85. An anti-slip pad 87 is fixedly connected to the lower end of the handle 85. The right end of the mounting block 82 is fixedly connected to the base 1. The upper part of the threaded rod 83 extends above the connecting cylinder 81, and the anti-slip pad 87 is located below the connecting cylinder 81.

[0033] The above solution involves rotating the throttle 85 to move the anti-slip pad 87 downwards, ensuring it adheres tightly to the ground and creating a stable limiting and fixing effect. This prevents the device from shifting due to force during batch bending, thus ensuring the safety and stability of the operation.

[0034] It should be noted that this utility model is a convenient positioning bending device for testing the strength of building materials. During use, the operator places the steel plate to be bent into the positioning groove 22, ensuring the upper left corner of the steel plate is tightly fitted with the inner corner of the positioning groove 22. This achieves right-angle positioning of the steel plate, ensuring accurate initial positioning. Subsequently, the operator moves the sliding plate 26 back and forth using the slider 25 to find a suitable fixing point. After finding the suitable point, the screw 27 is screwed into the corresponding threaded hole 24 to fix the position of the sliding plate 26. Then, the fixing rod 29 is rotated, causing the pad at the bottom of the fixing rod 29 to make tight contact with the upper part of the steel plate, thereby fixing the steel plate. The steel plate is fixed in the positioning groove 22 to prevent displacement during bending. After the steel plate is fixed, the hydraulic cylinder 5 is activated, which carries the bending plate to perform bending detection on the steel plate. In addition, the bottom of the base 1 is equipped with moving wheels 9. With the help of the moving wheels 9, the device can move flexibly, making it easy for operators to quickly move the device to the processing area of ​​batch steel plates, reducing the workload of manual handling of steel plates. When the device reaches the designated position, the operator turns the handle 85 to move the anti-slip pad 87 downward until the anti-slip pad 87 is in close contact with the ground, forming a stable limiting and fixing effect, preventing the device from shifting due to force during batch bending, and ensuring the safety and stability of operation.
