Device and method for detecting impact strength of powder metallurgy rod

The invention relates to the technical field of powder metallurgy rod impact strength detection, and discloses a powder metallurgy rod impact strength detection device and method.The device is characterized in that limiting assemblies are installed at the two ends of the bottom of a sliding frame respectively, guide assemblies are installed on the outer sides of the limiting assemblies, and a plurality of limiting holes are evenly formed in the outer wall of a connecting column; the limiting assembly is in limiting fit with the limiting hole. Through the arrangement of the limiting assembly, in the impact process, when an impact block makes contact with the surface of a metallurgical rod, a sliding frame has the stop moment, and when the impact block impacts the upper surface of the metallurgical rod, due to inertia, a gravity block extrudes a third spring, moves downwards and pushes a long rod, and the long rod moves out of a clamping groove. The first spring pushes the limiting block to move towards the out
