摘要

The drop forge hammer has a frame (1) for the ram (2) carrying the upper tool (3). The lower tool (4) is on a swing table (5a,5b) with a vertical movement in the frame and a hydraulic cylinder (7) to dampen the downward movement and return upwards after a forging stroke. The damper can also be a pneumatic cylinder or coil springs.
