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...

Abstract

The permanent magnetic punch includes a yoke iron, a punching head reciprocating up and down inside the yoke iron, and an armature connected to the punching head. The present invention features that the permanent magnetic punch includes also a magnetic driving mechanism to make the yoke iron and the armature to constitute one magnetic loop, and the magnetic driving mechanism is provided with electromagnetic mechanism to apply electromagnetic drive force to the armature and permanent magnet to apply permanent magnetic attraction force to the armature. The present invention is superior to available electromagnetic punch, which has great power consumption and complicated control system.

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the development of the electronics industry and the advent of the information age, traditional mechanical presses have been replaced by oil-free, clean, and high-frequency electromagnetic presses.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...
