Description

Technical Field

[0001] The utility model relates to the technical field of torsion testing machines, in particular to a vertical material torsion testing machine. Background Art

[0002] At present, metal sheets are often used in the existing aerospace, automobile manufacturing, machinery manufacturing, and construction and building materials fields. After assembly and installation, metal sheets may be subjected to torque rotation force during long-term use. If the metal sheet's resistance to torque rotation force is weak, torsional tearing and breakage may occur. Therefore, before assembling and installing metal sheets of related materials, it is necessary to conduct a torsion resistance test on the sample, and a vertical torsion test device will be used.

[0003] The vertical torsion test device is a machine device used to test the torsion resistance of materials or components. The vertical torsion test device is mainly used to evaluate the performance of materials when subjected to torque rotational force, and can measure the parameters of the material's ultimate torsional stiffness and fatigue performance.

[0004] Currently, most of the existing torsion testing devices for metal sheets cannot be adjusted and clamped for metal sheets of different lengths, which greatly reduces the application scope of the torsion testing devices for metal sheets.

[0005] In addition, the existing torsion testing device for metal plates may cause the metal plates to be twisted, torn and broken during the torsion test. The broken metal plates may easily collapse onto nearby workers, causing collision injuries, which greatly reduces the external protection of the torsion testing device for metal plates.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

The torque motor 3 is a high-torque motor and is durable.

[0028] The lifting cylinder 5 and the telescopic rod 51 form a set.

[0029] In detail, the button 22 and the display screen 21 are both arranged on the upper end surface of the control box 2. The control box 2, the torque sensor 32, and the display screen 21 are electrically connected. A PLC is preset in the control box 2. The PLC can display the torque value signal transmitted by the torque sensor 32 in real time on the display screen 21. The torque sensor 32 is a prior art.

[0030] Furthermore, the lifting cylinder and the telescopic rod 51 are a group, which are symmetrically arranged in two groups. The upper ends of the two telescopic rods 51 are fixed to the adjustment plate 52. The symmetrical lifting structure has strong stability, which ensures the lifting stability when adjusting the distance between the upper clamping plate 63 and the lower clamping plate 43.

[0031] Furthermore, the torque motor 3 is arranged in the central part of the workbench 1, the cross-section of the lower mounting frame 41 and the upper mounting frame 61 is an L-shaped structure and the interior is a front-to-back through-type frame cavity, the lower clamping cylinder 42 and the upper clamping cylinder 62 are respectively embedded in the through-type frame cavities of the lower mounting frame 41 and the upper mounting frame 61, and the embedded mounting structure realizes the overall protection effect for the lower clamping cylinder 42 and the upper clamping cylinder 62.

[0032] In more detail, the outer protective cover 7 is a frame-like structure with an open lower end, and is a PVC transparent material plate. There are two handles 71 which are symmetrically arranged on the outer wall surfaces at both ends of the outer protective cover 7. The PVC transparent material plate does not affect the staff covering the cover from observing the internal torsion test.

[0033] Generally speaking, the screw pin 8 is threadedly connected to the outer shield 7, and a screw pin cap 81 is provided at the top of the screw pin 8. The screw pin cap 81 is a diamond-shaped structure as a whole, and the diamond-shaped structure can be directly rotated by hand.

[0034] Finally, the impact-resistant layer 72 is evenly arranged along the inner wall surface of the outer shield 7. The impact-resistant layer 72 is made of glass fiber coating material and has a thickness of one millimeter. The glass fiber coating material has excellent wear resistance and impact resistance, and the main body is transparent.

[0035] Working method: If the vertical length of the metal sheet that needs to be torsion tested is a bit long, the cylinder 5 can be lifted by the cylinder to drive the telescopic rod 51 to extend upward, and the upper connecting strip 6, the upper mounting frame 61, the upper clamping cylinder 62, and the upper clamping plate 63 can be driven to move upward stably as a whole through the adjustment plate 52. At this time, the distance between the upper clamping plate 63 and the lower clamping plate 43 will increase. When the distance between the upper clamping plate 63 and the lower clamping plate 43 meets the size of the longer metal sheet to be clamped for the test, the lifting cylinder 5 is stopped.

[0036] Next, the metal sheet with the longer size is placed vertically between the two sets of upper clamping plates 63 and the lower clamping plates 43, and then the upper clamping cylinder 62 and the lower clamping cylinder 42 are started to drive the two sets of upper clamping plates 63 and the lower clamping plates 43 to stably clamp the upper and lower end surfaces of the metal sheet. Then, the torque motor 3 is started to drive the two lower clamping plates 43 to rotate counterclockwise at a horizontal average speed through the motor shaft 31, thereby driving the clamped part of the lower end of the metal sheet to rotate counterclockwise at a uniform speed. At the same time, the torque sensor 32 will The current torque value is transmitted to the control box 2 through the signal line, and the torque value will be displayed in real time on the display screen 21. When the metal sheet is twisted, torn and broken, the torque value displayed on the display screen 21 is the maximum torque value that the current metal sheet can withstand. By arranging a symmetrical lifting cylinder 5 on the workbench 1 and arranging an adjustment plate 52 structure on the telescopic rod 51 of the lifting cylinder 5, the metal sheets of different lengths can be lifted and adjusted and stably clamped, which greatly improves the application range of the torsion test device for metal sheets.

[0037] Moreover, after the metal sheet is stably clamped, the external protective cover 7 is first used to cover the entire workbench 1, and then the screw cap 81 is rotated clockwise to drive the screw pin 8 to rotate clockwise and lock it with the screw groove 11. The torsion test can then be carried out. This can prevent the torn and broken impurities of the metal sheet material from directly collapsing onto nearby workers and causing collision injuries during the torsion test, greatly improving the external protection of the torsion test device for metal sheets.

[0038] In addition, by providing an impact-resistant layer 72 structure on the inner wall surface of the outer shield 7, the impact-resistant service life of the inner wall surface of the outer shield 7 is further improved.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
