Description

technical field

[0001] The invention relates to a punch press, in particular to a permanent magnet punch press adopting a permanent magnet electromagnetic mechanism. Background technique

[0002] With the development of the electronics industry and the advent of the information age, traditional mechanical punches are replaced by electromagnetic punches that are oil-free, clean, and of high frequency. Figure 1 is a schematic structural diagram of a known electromagnetic punch. As shown in Figure 1, the electromagnetic mechanism is set on the frame, and the electromagnetic mechanism is composed of a yoke, an electromagnetic coil, a coil frame and an armature with a non-magnetic punch. The armature is connected with the guide sleeve plate, and the guide sleeve plate can move up and down in the guide post. Its working principle is: when the current is applied to the electromagnetic coil, the armature is moved downward by the electromagnetic driving force, and the spring is comp...
