Description

Technical field

[0001] The invention relates to a punching machine, in particular to a permanent magnet punching machine 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the development of the electronics industry and the advent of the information age, traditional mechanical presses have been replaced by oil-free, clean, and high-frequency electromagnetic presses. figure 1 It is a schematic diagram of the structure of a known electromagnetic punch. Such as figure 1 As shown, the electromagnetic mechanism is arranged on the frame, and the electromagnetic mechanism is composed of a yoke, an electromagnetic coil, a coil former 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 current is applied to the electromagnetic coil, the armature moves downward by the electromagnetic driving force, and at th...

Embodiment Construction

[0035] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] figure 2 It is a schematic diagram of the structure of the permanent magnet punch of the present invention. Such as figure 2 As shown, the permanent magnet punch of the present invention includes a frame 1, a yoke 2, an end plate 9, a guide column 6 and a limit plate 7, which are sequentially connected, and also includes a punch spindle 3 penetrating through the yoke 2, and the punch spindle 3 is composed of a punch 31, an armature 32 and a guide plate 33 connected in sequence. The end plate 9, the bottom surface of the yoke 2 and the support 1 are all provided with through holes for the punch spindle 3 to pass through. The electromagnetic coil 5 that generates the electromagnetic field is arranged in the circular space between the inner wall of the yoke 2 and the punch spindle 3. The electromagnetic field generated by it generates an elec...
