The utility model relates to the technical field of
steel quality detection, in particular to a quality detection device for high-strength steel, which comprises a shell and an
impact component. Through the cooperation of the screw rod and the rotating nut, the
impact hammer head can be accurately controlled to move, so that the
impact strength is adjusted, through the engagement of the upper end of the screw rod and the rotating nut, the
impact hammer head can be controlled to move up and down through simple rotating action, and through the design of a ball and a
handle arranged in the rotating nut, the impact strength is adjusted. According to the utility model, through the design of the magnetic attraction clamping seat and the chamfer of the striking hammer head, the transmission path of force is optimized, and the design of the chamfer of the striking hammer head and the magnetic attraction clamping seat is helpful for reducing the
stress concentration in the striking process, and the high-strength steel detection device allows the detection of high-strength steel of different specifications and types, and improves the detection efficiency. The problem that the accuracy of evaluating the
impact resistance and the
fracture toughness of the material is poor due to insufficient detection strength is effectively solved.
