Description

Technical Field

[0001] The utility model relates to the technical field of sample clamping, in particular to a dangerous cross-section sample cutting and clamping tool. Background Art

[0002] Dangerous section refers to the maximum stress section in material mechanics. Under the same external force conditions, the stress of sections at different positions is different. The stress of the cross-section size will also be different. As long as the stress is the largest, it is a dangerous section. Because the material is destroyed when the stress is too large to exceed the strength limit of the material. The dangerous section is a weak point that may appear during actual production and use. If it is not properly operated or used for too long, it may cause safety problems such as material breakage and damage. In the design and use of parts, attention should be paid to the inspection and protection of dangerous sections. For example, a new hook should be subjected to a load test and can only be used after passing the test. In addition, the hook should be checked frequently during use to see if there are cracks or severe deformation, corrosion and wear.

[0003] It is often necessary to conduct special inspections on dangerous sections of parts to determine whether the parts meet the use requirements. Homemade magnets are generally used in combination with existing fixing means to fix and cut the test parts to obtain dangerous section samples. Because the parts for cutting and testing dangerous section samples are generally in sheet form, the existing fixed tooling can easily affect the cut parts during the cutting process, causing them to shift, even if it is combined with magnet adsorption, and the processing quality of the dangerous section samples cannot be guaranteed.
