Abstract: An online continuous follow-up punching device. A moveable working platform (17) is provided above a fixed working platform (15) via a guide rail (2) and a slider (18). A second servo motor (12) is fixed on the fixed working platform (15). A ball screw (4) is connected to a shaft end of the second servo motor (12). A nut of the ball screw (4) is fixed at a lower side of the moveable working platform (17). A first servo motor (5) is fixed on the moveable working platform (17), and the first servo motor (5) is drivingly connected to a crankshaft (7). One end of a connecting rod (8) is connected along a shaft diameter of the crankshaft (7), and a guide rod (10) is connected to the other end of the connecting rod (8). The guide rod (10) engages with and passes through a guide rod base (11). A punch (27) is connected to a free end of the guide rod (10), and a die base (23) is provided on a front side of the punch (27). A recessed die (24) is provided in the die base (23). A material feeding mechanism is further provided on the moveable working platform (17). During an operation, the device is placed on an automatic sheet metal processing production line, and the ball screw (4) drives the moveable working platform (17) to move synchronously with a workpiece (28); and during movement, the first servo motor (5) drives the punch (27) to punch a hole. The device is suitable for punching a specially-shaped sheet metal workpiece (28), and has high production efficiency and good punching accuracy.
