Problems solved by technology

[0003] Existing electric punch press generally comprises motor, is connected with running wheel on the motor, and described running wheel and flywheel are driven by belt, and described flywheel is connected with crankshaft, and described crankshaft is provided with punch, and described punch is provided with upper Die, when this kind of electric punching machine is punching, the flywheel is driven by the motor to rotate, so that the crankshaft drives the punch to move up and down to realize punching. In the field of punching holes in plastic sheets, the punching force is not large, so manual operation can be used. Existing electric punching machines generally only have a single electric operation, and it is not convenient to use a motor to drive the punching machine in case of a power failure or when punching a sample.

Abstract

The invention discloses an electric punching machine comprising a motor. A rotating wheel is connected to the motor. The rotating wheel is in transmission with a flywheel through a belt. The flywheel is connected with a bent axle. A punch is arranged on the bent axle. An upper die is arranged on the punch. The motor comprises a stator and a rotor. The rotor is fixed on a rotating shaft. The rotating shaft is rotationally connected to a support frame. A sliding rail is arranged at the bottom of the stator. The sliding rail is parallel to the rotating shaft. A rocking handle is arranged at the end of the rotating shaft. During normal working of the punching machine, the rotor is electrified to rotate to drive the rotating shaft to rotate, the rotating shaft drives the rotating wheel to rotate, the rotating wheel drives the flywheel to rotate, and the flywheel drives the bent axle to rotate to realize punching. During power failure, the rotating shaft bears large electromagnetic resistance due to direct rotation, so that the stator is slid towards the other side of the sliding rail to a position where the rotor is slid out, and then, the rocking handle is rotated to realize punching.

Description

technical field [0001] The invention relates to an electric punching machine for punching holes, in particular to a punching machine which can be punched manually when the power is cut off. Background technique [0002] Punch production is mainly for sheet metal. Through the mold, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts can be made, which are widely used in various fields. [0003] Existing electric punch press generally comprises motor, is connected with running wheel on the motor, and described running wheel and flywheel are driven by belt, and described flywheel is connected with crankshaft, and described crankshaft is provided with punch, and described punch is provided with upper Die, when this kind of electric punching machine is punching, the flywheel is driven by the motor to rotate, so that the crankshaft drives the punch to move up and down to realize punching. In the field of punching holes in plas...
