[0020] Compared with the prior art, the invention has the following beneficial effects: the workpiece punching device with a disengagement conveying mechanism,

[0021] (1) The present invention automatically assists in limiting the punching workpiece, automatically detaching and conveying the punching and shearing workpiece, automatically feeding the punching and shearing workpiece, and has the advantages of internal cleaning after the punching and shearing work is completed. With the assistance of the vacuum machine, the suction head at the top of the suction pipe is used to suck and fix the top of the punched workpiece with auxiliary negative pressure to prevent the punched workpiece from falling and ensure the detachment effect of the punched workpiece. When the upper punching and shearing die moves upward, with the assistance of the first fixed plate, the first slide groove, the first connecting plate and the connecting rod, the first baffle moves to the right to the lower side of the die groove, the vacuum machine is turned off, and the hydraulic cylinder in the upper punching and shearing die drives the push plate to move through the hydraulic rod. The push plate pushes the workpiece in the die groove out and finally moves it out through the first conveyor belt. No manual operation is required, which increases practicality.

[0022] (2) After the workpiece is punched, it is attached to the lower punching die. The hydraulic cylinder in the lower punching die drives the push plate through the hydraulic rod to push the workpiece out. With the assistance of the mechanical gripper fixed on the lower side of the manipulator, the single workpiece is clamped and moved to the second conveyor belt. For example, after punching a long thin plate, the thin plate is moved with the assistance of the feeding assembly. Finally, the thin plate and the punched piece are moved together. The punched piece falls on the second conveyor belt. The thin plate moves with the assistance of the guide roller on the support plate, so that the punched piece is separated from the feeding assembly, thereby increasing practicality.

[0023] (3) The present invention uses a mechanical gripper to load and unload the workpiece with the assistance of a manipulator, thereby increasing practicality, and drives the high-pressure blowing nozzle on the second connecting plate to adjust its position with the assistance of the manipulator. The air booster pressurizes the filtered air and then enters the high-pressure blowing nozzle through the air pipe. With the assistance of the high-pressure blowing nozzle, the upper punching die, the lower punching die and the inside of the punching box are processed, thereby preventing debris from sticking to the upper punching die or the lower punching die and affecting the quality of other workpieces.
