Description

Technical Field

[0001] This utility model belongs to the field of metal product processing technology, and in particular relates to a hardness testing device for metal product processing. Background Technology

[0002] After metal products are manufactured, their performance needs to be tested. One of the most important performance indicators of metal products is hardness. When testing the hardness of metal products, the hardness testing device mainly consists of three parts: a test platform, an impact hammer, and a test piece. The test platform is used to support the metal product, the impact hammer is used to hammer the metal product on the test platform, and the test piece is used to detect the hammered position on the metal product.

[0003] Chinese patent application CN221148384U discloses a device for testing the hardness of self-tapping screw heads. The device includes a main body and further includes: a screw-tightening device on the upper inner side of the main body that can simulate the action of a screwdriver; a torque measuring device on the lower end of the main body that can compare the torque of the screws during hardness testing, thereby improving accuracy; a hydraulic telescoping device fixedly connected to the upper end of the main body, with its output end extending through the upper end of the main body; and a controller fixedly mounted on one side of the main body, which includes a speed adjustment knob and a lifting control button. This invention, by incorporating a screw-tightening device, effectively simulates the effect of manually rotating a screwdriver for hardness testing of screws.

[0004] The aforementioned self-tapping screw head hardness testing device has a limiting cylinder on its limiting frame, and a movable plate is movably mounted inside the limiting cylinder. The upper side wall of the movable plate has a screw fixing groove for receiving screws. This means that when testing the hardness of metal products, the screw must be placed in the screw fixing groove on the movable plate. However, the opening and depth of this fixing groove are not adjustable, thus limiting the size of the screw to be tested. This indicates that the device can only test metal products with screws of specific sizes. Furthermore, it includes a torque testing structure to obtain the screw's strength by testing its torque. However, screw torque data is difficult to collect, and the data collection time is long, making it unsuitable for batch testing of metal product hardness and causing production delays. Therefore, we provide a hardness testing device for metal product processing to solve the above-mentioned problems. Utility Model Content
