Technical Field

[0001] The utility model relates to the technical field of titanium steel composite plate testing, and more specifically to a titanium steel composite plate bending strength testing frame. Background Art

[0002] Titanium-steel composite plate is a composite material that combines the corrosion resistance of titanium and the strength of ordinary steel plates. This material cost is relatively low, so it is widely used in various fields. Titanium-steel composite plates need to be tested for bending strength during the processing and production process, which requires the use of a titanium-steel composite plate bending strength test stand for the test operation.

[0003] The utility model patent with the existing patent announcement number CN207396191U discloses a bending strength test frame for aluminum-plastic composite panels. The patent mainly comprises a plurality of detachable templates connected through a lower pressing template group. The height of the entire lower pressing template group can be adjusted by combining different templates, thereby adjusting the distance between the bottom of the lower pressing template group and the aluminum-plastic composite panel, thereby improving the overall test efficiency. However, the bending strength test frame still has the following defects:

[0004] During the test of the above-mentioned bending strength test stand, although the bending force of the titanium-steel composite plate can be known by pressing down when it is bent, it is difficult to know the specific bending depth of the titanium-steel composite plate. Different depths will also lead to different bending forces. It is difficult to ensure consistent depth for pressure strength tests, which affects the accuracy of the bending strength test. Therefore, it is necessary to provide a titanium-steel composite plate bending strength test stand. Utility Model Content
