[0002] Impact test is a dynamic mechanical properties test, mainly used to determine the work consumed in breaking a sample metal of a certain shape. It is also called impact toughness test. The purpose of the test is to determine whether the various properties of metal products fail when they are subjected to a series of impacts at normal and extreme temperatures. After the production of metal products is completed, the finished products need to be sampled and impact tested.

[0003] After searching, CN 219675730 U, an impact detection device for metal processing, can adjust the height of the lifting plate by setting an adjustment component, and the lifting plate drives the carrying plate to adjust the height through a connecting rod, so that the impact height of the impact block can be easily adjusted. Since the height of the impact block can be precisely controlled, its rising accuracy is improved, so that the impact force detection data of the metal product is more accurate, and the reliability of the device is improved.

[0004] However, there are still certain defects in the above application: in the above application, when the impact block freely falls from a certain height and hits the metal product, due to the effect of elasticity, the impact block will generally be ejected to other positions of the impact point. When performing secondary or multiple impact tests, it is usually necessary to manually straighten the position of the impact block, and then clamp and lift the impact block for a second time. The entire detection process has the defects of cumbersome operation and low efficiency. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

By setting the winding wheel 7, the pull rope 8 and the electromagnet 9, the winding wheel 7 can lift the impact block 2 while being driven to rotate. After the impact block 2 is lifted to the specified height, it only needs to cut off the power to the electromagnet 9, and the impact block 2 will fall freely and hit the metal product vertically.
