Description

Technical Field

[0001] The utility model relates to the technical field of metal product production, in particular to a strength testing device for metal product production. Background Art

[0002] The metal product industry includes the manufacture of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily metal products, etc. During the production of metal products, it is necessary to detect the strength of its products. Therefore, a strength testing device for metal product production is needed for detection. Among them, the "tensile strength testing device for metal products" disclosed in the patent application number "CN218766365U" has solved the problems that the existing tensile strength testing devices usually adopt manual holding or a relatively single tensile method for stretching, resulting in low testing efficiency, large deviation in the test results, and there is no better way to fix the metal products during the stretching process. However, in actual use, there are still many defects in the strength testing devices for metal products with similar structures. For example, they do not have a safety protection function. When the metal product breaks during the tensile strength detection, it cannot block the metal block, resulting in easy injury to the detection personnel and reducing the safety of the device during detection; they do not have the function of automatically collecting metal scraps and metal blocks, resulting in metal scraps and metal blocks being scattered in the detection equipment, affecting the detection of the detection equipment and increasing the cleaning burden of the staff. Therefore, a strength testing device for metal product production needs to be designed. Content of the Utility Model
