Electromagnetic punching machine with punched hole detection device

Abstract

The invention discloses an electromagnetic punching machine with a punched hole detection device. The electromagnetic punching machine comprises a machine body, an upper fixing block and a lower fixing block are arranged in the machine body, a through hole is formed in each of the upper fixing block and the lower fixing block, a sliding rail is arranged in each through hole, a punching rod is slidably arranged on the sliding rails, the bottom of the punching rod is connected with an upper die, a flange is arranged at the upper end of the punching rod, an elastic member is arranged below the flange, the lower side of the elastic member is abutted against the upper fixing block, a plurality of magnets are wound on the outer side of the punching rod, a lead is wound in the middle of the punching rod, a shell is arranged outside the magnets, ventilation ports are arranged on two sides of the shell, and a fan is arranged on one side of one ventilation port. When punching is needed, the lead is electrified to enable the punching rod to punch downwards to realize punching operation; after punching is completed, power is cut off, and the punching rod is rebounded to an initial position by the elastic member to realize punching operation; heat radiation of the lead is accelerated through air draft of the fan.

Description

technical field

[0001] The invention relates to the technical field of punching machines, in particular to an electromagnetic punching machine with a punching detection device. 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. Existing punch presses generally drive the flywheel through the motor, and the flywheel drives the punch to punch, or the hydraulic system controls the punch to punch, the structure is relatively complicated, and the manufacturing cost is relatively high. When stamping small holes, because the punch of the stamping die is thin, the punch is easy to break during stamping, or the punch may not be opened due to wear and other reasons, but now the plate punching process generally uses The automatic feeding device continuously feeds the material, and worker...
