The specific embodiment

See also Fig. 1,2,3,4,5, comprise: a body 1 with board 2, upper fixed seat 3, die holder 4, a die assembly 100, several need the oil pressure claming holder 30 of quantity to constitute according to setting; Wherein,

The die holder 4 of one body 1, be linked to the lifting shaft of the upper fixed seat 3 of body 1, be and comply with control and lifting, its periphery is provided with sets frame 8, oil pressure claming holder 30 can be hung when not using, its bottom surface is provided with laterally, directly to combination slot 7, and be able to embedding group oil pressure claming holder 30, thus the patrix 20 of folder fixed mold assembly 100;

The board 2 of one body 1, its periphery also are provided with sets frame 8, and oil pressure claming holder 30 can be hung when not using, also be provided with above it laterally, directly to combination slot 7, and be able to embedding group oil pressure claming holder 30, thus the bed die 10 of folder fixed mold assembly 100;

One die assembly 100, include patrix 20, bed die 10, this patrix 20 includes combined integrated positioning module 21, punching bar 22, flexible material returned mould 23, its whole group is fixed in die holder 4 bottom surfaces of body top, all around and folded fixed by each oil pressure claming holder 30, and whole can lifting with the lifting of die holder 4, again, punching bar 22 passes positioning module 21, when descending, positioning module 21 can be to circuit board 9 materials and parts compression sets, punching bar 22 can be to circuit board 9 punchings, and when rising, flexible material returned mould 23 can retreat in positioning module 21 and patrix 20, contract behind the punching bar 22 and allow, and then make circuit board 9 total detachments; This bed die 10, include combined integrated shaping mould 11, shaping mould 11 is unsettled and is laid with the perforation 12 that needs the position according to the circuit board punching, its whole group is fixed on the board 2 of body, all around and folded fixed by each oil pressure claming holder 30, put on the shaping mould 11 and decide circuit board 9 materials and parts, and born punching again;

One oil pressure claming holder 30, be set as in the top of a body 31, be provided with an oil hydraulic cylinder 32, the upper surface is provided with clamping and fixing block 34, clamping and fixing block 34 is provided with fulcrum D, lifts up about being able to, again, oil hydraulic cylinder 32 has expansion link 33, stretch out and a bottom face of jacking clamping and fixing block 34 when being imported oil pressure, produce the downward oblique deascension of the other end, and then can be able to powerful folder fixation in die assembly patrix 20, the bed die 10 of its below;

By said structure, effect of the present utility model, effect, advantage now are described in detail as follows:

One, aspect " body is assembled, is detached in to die assembly 100 ":

Die assembly 100 patrixes 20 integrated members are placed the desired location of body die holder 4 bottom surfaces, again each oil pressure claming holder 30 is taken off from setting frame 8, embed respectively die holder 4 laterally, directly to combination slot 7, form arrangement combinations around patrix 20, oil pressure can be imported the oil hydraulic cylinder 32 of each oil pressure claming holder 30, make its expansion link 33 pushing tow clamping and fixing blocks 34, clamping and fixing block 34 can press from both sides decides patrix 20.Otherwise, when desiring to pull down patrix 20 and integrated member thereof, support patrix 20 earlier, let out oil pressure again except that each oil pressure claming holder 30, can remove each oil pressure claming holder 30 one by one, and be pulled down patrix 20.

And bed die 10 and shaping mould 11 thereof placed desired location above the body board 2, and also be each combination slot 7 that each oil pressure claming holder 30 is arranged in board 2, also be able to the oil pressure folder and decide bed die 10.Otherwise, also be can let out except that oil pressure, remove oil pressure claming holder 30 and separate bed die 10.

As shown in the above description, the utility model can make and tear open, organize die assembly, is had laborsaving, quick, convenient, easy effect, reaches splendid practical effect.

Two, aspect " punching, the material returned ":

When die holder 4 descends, also descends together with the integrated member of patrix 20, its punching bar 22 can be with circuit board 9 materials and parts punchings, and simultaneously, its positioning module 21 can be comprehensively circuit board 9 and presses, the problem of taking precautions against circuit board 9 to be subjected to impulse force and lifting up reaches splendid punching accuracy effect.

When punching is finished, die holder 4 rises and patrix 20 integrated members also rise, the flexible material returned mould 23 that patrix 20 and positioning module are 21 can retreat, allow each punching bar 22 also be stepped back, shorten the length of stretching out positioning module 21, therefore, can allow the punching bar 22 that runs through circuit board 9 can strip circuit board 9, reach circuit board 9 total detachment punching bars 22, do not have the problem that snarls punching bar 22, placed on the shaping mould 11, for extremely convenient taking-up and be to break away from.

Three, aspect " firm position of die assembly 100 ":

Die assembly 100 of the present utility model, be subjected to " all around ", " a plurality of " oil pressure claming holder 30 folded fixed, and, be to be the oil pressure folder to decide, this oil pressure can be transferred according to the weight of die assembly and establish extremely strong big oil pressure, being able to can be powerfully fixed to its folder, again, be to be clamping and fixing block 34, oil pressure folder calmly, non-is " thread " locking, therefore, and except bearing the reaction force of powerful punching impulse force, and never had the picture thread because of the loosening problem of vibrations, reached splendid firm effect, and the good effect of security that can wrongly not come off.

In sum, structure of the present utility model, composition in " circuit board punching apparatus " field of articles, are unprecedented designs really, and the effect of being reached also has splendid practicality really and promotes effect.
