Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.

See a kind of electromagnetic-permanent magnetic drive-type dual-direction ram machine shown in Fig. 1, Fig. 2, the punch process for slim workpiece 9 in support (not shown) is located at by this dual-direction ram machine.This dual-direction ram owner will comprise electromagnetic-permanent magnetic dual direction drive mechanism and be located at two presser's station 7 of this electromagnetic-permanent magnetic dual direction drive mechanism left and right sides.

Shown in Fig. 1, Fig. 2, electromagnetic-permanent magnetic dual direction drive mechanism comprise the hollow form be fixedly installed yoke 1, be housed in DC coil 2 in this yoke 1 inner chamber regularly, be located in armature 3 in DC coil 2 regularly, lay respectively at the axial both sides of armature 3 and can two punch assemblies 10 moving vertically of armature 3 relatively.The axial line of armature 3 distributes in left-right direction, and two namely above-mentioned punch assemblies 10 are located at the left and right sides of armature 3 respectively to carry out punch process to the slim workpiece 9 in both sides presser's station 7 respectively.

Each punch assembly 10 includes sliding part 4, be located on sliding part 4 medial end with close on armature 3 permanent magnet 5, be located in sliding part 4 outboard end to realize the drift 6 of punch process.On the punch assembly 10 of armature 3 both sides, end pole permanent magnet 5 closing on armature 3 is arranged on the contrary, that is, if the permanent magnet in left side 5 is near the end of armature 3, that is the right part of permanent magnet 5 is N pole, then the permanent magnet 5 on right side is near the end of armature 3, that is the left part of permanent magnet 5 is then S pole.

Shown in Fig. 1, Fig. 2, the medial end of sliding part 4 offers accepting groove, permanent magnet 5 is embedded regularly in this accepting groove.The outer end, both sides of yoke 1 all has the perforation 11 that can penetrate slidably for permanent magnet 5 correspondence, the medial end of permanent magnet 5 penetrates in perforation 11 with may correspond to, the diameter of sliding part 4 is greater than the aperture of perforation 11, thus can keep out spacing to form slip in the outer end of yoke 1 when punch assembly 10 moves towards armature 3.Support is provided with the guide rail 8 providing sliding part 4 along glide direction slide-and-guide, realizes the accurate punching press of punch assembly 10 to slim workpiece 9 to guarantee that sliding part 4 horizontally slips.In the outboard end of sliding part 4, drift 6 is one or more, and user can be selected according to the requirement of actual punch process.

Slim workpiece 9 to be processed transmits along the longitudinal direction in presser's station 7, and presser's station 7 is provided with material-dropping hole 71 in the position of corresponding drift 6, discharges with the waste material produced for punching press after the slim workpiece 9 of drift 6 punching press.

Like this, when DC coil 2 is not energized, because armature 3 is ferromagnetic metals, produce attraction between permanent magnet 5 and armature 3, punch assembly 10 is near armature 3.When the slim workpiece 9 of processing to be punched is ready in presser's station 7, DC coil 2 is energized and generation current, armature 3 produces magnetic, the magnetic at armature 3 two ends should be contrary with the magnetic pole of both sides permanent magnet 5 respectively, even the permanent magnet 5 in left side is N pole near the end of armature 3, the permanent magnet 5 on right side is S pole near the end of armature 3, and so armature 3 left end is N pole, right-hand member is S pole.Like this, repulsion is produced between the permanent magnet 5 of armature 3 and both sides.Between armature 3 and permanent magnet 5 repulsion effect under, the punch assembly 10 of both sides relatively armature 3 outwards slides, and then the punch process making the drift 6 of both sides realize slim workpiece 9, and the waste material after punch process is discharged by material-dropping hole 71.After punching press, DC coil 2 power-off, between permanent magnet 5 and armature 3 gravitation effect under, the punch assembly 10 of both sides all inwardly slides towards armature 3 and realizes resetting, and automatically realizes backhaul.When next station of the slim workpiece 9 of both sides arrives stamping position, DC coil 2 is energized again, makes the punch assembly 10 of both sides outwards slide and again realize punch process.So repeatedly, the lasting punch process to the slim workpiece in both sides 9 is just achieved.

In prior art, general electromagnetic drive mechanism is all armature motion, and can not carry out bi-directional drive simultaneously, and the armature 3 in the present invention is fixing, coordinates the permanent magnet 5 at two ends, can realize two-way simultaneous very easily and drive.In electromagnetic-permanent magnetic dual direction drive mechanism of the present invention, the drift 6 only adopting an armature 3 just can order about both sides moves vertically and realizes the synchronous punch process to the slim workpiece in both sides 9.By controlling continuous energising and the power-off of DC coil 2, just this dual-direction ram machine can be made constantly to carry out dual-direction ram processing to slim workpiece 9, improve the production efficiency of punch process significantly, simultaneously the structure of this dual-direction ram machine very simple, with low cost, be easy to realize.

Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
