Punching device for electromagnetic punching machine

Abstract

The invention discloses a punching device for an electromagnetic punching machine. The punching device comprises a workbench, a fixed seat, an upright post, a mounting seat, a punching head, a punching rod, a punch, an energy storage spring, a sliding block and a reset spring, wherein the workbench is fixedly connected on a rack; the fixed seat is fixedly connected in the central position of the workbench; the upright post is vertically and fixedly connected on the back side of the workbench; the mounting seat is arranged on the upright post; the punching head is fixedly connected at the lower end of the mounting seat; a through hole is formed in the lower end of the punching head; the punch is inverted-T-shaped; the punch is mounted inside the punching head; the punch penetrates through the through hole of the punching head; the reset spring sleeves the punch; the sliding block is connected in the punching head in a sliding manner; the punching rod is a working rod of the electromagnetic punching machine; the punching rod is positioned right above the sliding block; the energy storage spring is arranged inside the punching head; the upper end of the energy storage spring is fixedly connected with the sliding block; and the lower end of the energy storage spring is fixedly connected with the punch. The punching device has the advantages that the structure is simple, the impact force is large, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of electromagnetic punching machines, in particular to a punching device for electromagnetic punching machines. Background technique [0002] The existing electromagnetic punching machine is a punching device that uses the magnetic attraction force generated by the electromagnet coil to be powered. Because of its compact structure, small size, and simple operation, it is widely used in metal stamping, cutting, riveting, etc. The existing electromagnetic stamping machine is mainly composed of a base, an electromagnetic coil, a static armature, a moving armature, a stamping rod and a punch. There is an electromagnetic coil and a static armature inside. The movable armature is fixed to the stamping rod and is located above the static armature. The stamping rod passes through the center of the electromagnetic coil and its lower end corresponds to the punch. The lower end of the installation sleeve is connected t...

Problems solved by technology

During the use of this electromagnetic punching machine, the punching rod hits the punch and moves downward until it hits the workpiece, the punching force is small, and the range of applicable punching workpieces is small

[0003] At the same time, when the electromagnetic punching machine stamps the workpiece, the punch and the concave part of the workpiece will form a huge friction force. When the punch shrinks, the huge friction force will lift the workpiece from the working head, causing damage to the equipment and staff. huge damage
