The specific embodiment
Fig. 3 shows the schematic diagram of electromagnetic pulse cutting device of the present invention.Electromagnetic pulse cutting device 3 is used to shear workpiece 4, and electromagnetic pulse cutting device 3 comprises: mould 31, rolled-up stock 32 and electromagnetic punch 33.Mould 31 has die cavity 311, mould 31 supporting workpieces 4.Wherein, workpiece 4 can be metal material, and perhaps, workpiece 4 also can be non-metallic material.
Rolled-up stock 32 is arranged at workpiece 4 tops and is positioned at top, die cavity 311 edges relative position, when rolled-up stock 32 presses down, produces compression with compacting workpiece 4, and prevents that workpiece 4 from producing material horizontal and flowing.Preferably, rolled-up stock 32 is an annular slab, wherein, rolled-up stock 32 has first location division 321, when rolled-up stock 32 presses down, and the described workpiece 4 of first location division, 321 compactings, and form the shape of form fit first location division 321 of 41, the second location divisions 41, second location division in workpiece 4 corresponding sections.In the present embodiment, first location division 321 is a protuberance, and second location division 41 is a recess, and for example: described protuberance is the dentation flange, and described recess is the dentation groove.But described protuberance is not defined as the dentation flange, and described recess is not defined as the dentation groove, and it also can be the shape of working in coordination.
In the present embodiment, dielectric material 34 and head part 35 during electromagnetic pulse cutting device 3 comprises in addition.In dielectric material 34 be arranged on the workpiece 4 and in the groove of rolled-up stock 32.Preferably, middle dielectric material 34 is an elastic material.Head part 35 is arranged in the die cavity 311 and contacts described workpiece 4, so that the shore power opposite with workpiece 4 shear directions to be provided, to keep the smooth of workpiece 4.Be noted that, unlike material and difformity according to workpiece 4, head part 35 can be elastic fluid or rigid material, when head part 35 is elastic fluid, the power of shoring that is produced can be provided by the mould 31 of periphery, when head part 35 was rigid material, the power of shoring that is produced can be provided by other peripheral equipment (being spring in the present embodiment).
When shearing technology, earlier workpiece 4 is positioned between mould 31 and the rolled-up stock 32, rolled-up stock 32 is pressed down again, first location division 321 of rolled-up stock 32 produces compression with compacting workpiece 4, and form second location division 41 in workpiece 4 corresponding positions, to prevent that workpiece 4 from producing material horizontals and flowing.When pulse current passes through coil portion 332, can make drive block 331 produce vortex flow and induced field, because the induced field of drive block 331 is opposite with the magnetic direction of coil portion 332, therefore can produce powerful repulsive interaction between drive block 331 and the coil portion 332, make drive block 331 move downward and oppress in dielectric material 34, and then make workpiece 4 under the pressure effect of middle dielectric material 34 and mould 31, produce to shear and separate.
Utilization of the present invention is arranged at first location division 321 of the rolled-up stock 32 of top, die cavity 311 edges relative position, and workpiece 4 is produced compression with compacting workpiece 4, and prevents that workpiece 4 from producing material horizontal and flowing.And, utilize the head part 35 that is arranged in the die cavity 311 that the shore power opposite with workpiece 4 shear directions is provided, to keep the smooth of workpiece 4.By this, electromagnetic pulse cutting device of the present invention 3 shears that workpiece 4 resulting sections are smooth almost not to have burr, and the angular zone that collapses is little, perpendicularity is good, and the restriction of workpiece 4 no materials, and metal and nonmetallic materials all can be sheared processing.Moreover the simple structure of electromagnetic pulse cutting device 3 of the present invention only needs one-sided shearing die, so the long service life of mould 31, manufacturing expense is low and do not have the restriction in die-cut gap.
The foregoing description only is explanation principle of the present invention and function thereof, and unrestricted the present invention.Therefore the those skilled in the art makes amendment to the foregoing description and changes and still do not break away from spirit of the present invention.Interest field of the present invention should be listed as appending claims.
