IMPACT MACHINE DEVICE USING RESTORING FORCE

摘要

PURPOSE: An impact testing device with the force of restitution is provided to apply impact of identical intensity to a sample by freely fall a hammer at a predetermined height and to provisionally make the hammer collide with the sample, thereby accurately obtaining test data. CONSTITUTION: An impact testing device with the force of restitution a recovering force includes a hammer unit (100), a link unit (200), a body unit (300), a height adjusting unit (400), a supporting unit (500), and a spring unit. The hammer unit is fallen in a sample direction and applies impacts on a sample. The link unit is extended from the hammer unit to one side. The body unit is connected to the link unit and rotated to be integrated with the link unit. The height adjusting unit adjusts the falling height of the hammer unit and includes a latch plate (430) and a stopper (410). The supporting unit supports the height adjusting unit and the body unit. The spring unit is arranged in the supporting unit and provides the repulsive power to the body unit.
