Detailed description of the invention

The invention discloses one and rush aperture print technique: the first step, first time rushes aperture, and going out a degree of depth is the aperture of h; Second step, indentation print; This aperture extrudes the diameter gravure larger than the diameter of aperture, and the degree of depth h ' of this gravure meets h ' < h; The waste material that indentation print produces falls into aperture, such that gravure is perfectly disposable to be gone out, reach good effect; 3rd step, second time rushes aperture, again to small hole punching, is rushed out making the waste material falling into aperture in second step.

Embodiment one:

Aperture print technique is rushed, for backboard 3 as depicted in figs. 1 and 2 for rushing the object of aperture print described in embodiment one.Backboard 3 is the platy structure in bat shape, and a long side is arc-shaped and is provided with an outside dome arc 33 in this middle side edge position.Then utilize the aperture print technique of rushing described in embodiment one to go out aperture 31 that the degree of depth is h and the coaxial gravure 32 that the degree of depth is h ' at the medium position place of dome arc 33.The diameter of aperture 31 is less than the diameter of gravure 32, and the degree of depth h ' of gravure meets h ' < h.When rushing aperture print, the first step, to go out a degree of depth be the diameter of h is the aperture 31 of 5mm; Second step, aperture 31 extruding diameter is the 10mm gravure 32 coaxial with aperture 31, and the degree of depth h ' of this gravure meets h ' < h, and the waste material of now indentation print generation falls into aperture 31, make that gravure is perfectly disposable to be gone out, reach good effect; 3rd step, again to aperture 31 punching, goes out the waste material falling into aperture 31 in second step.As the explanation to embodiment one, the diameter of aperture 31 is not limited to 5mm, and the diameter of gravure 32 is also not limited to 10mm.

Embodiment two:

As shown in Fig. 2 and Fig. 3 embodiment two, rush the punching die of aperture 31 for the first step in the technique described in embodiment one and the 3rd step, comprise be provided with red needle 12 patrix 1, coordinate the counterdie 2 placing backboard 3 with patrix 1; Counterdie 2 is provided with the three-point fix structure coordinated with this backboard 3.

Patrix 1 is provided with stripper 11, upper mould fixed plate 14, the red needle 12 towards counterdie 2 be connected with upper mould fixed plate 14 and the axis of guide 13.The gathering sill 21 that counterdie 2 is provided with counterdie backing plate 22 and coordinates with the axis of guide 13.

Three-point fix structure is a leg-of-mutton location structure: the position that counterdie 2 places backboard 3 is provided with the first locating piece 23 coordinated with dome arc 33; The second locating piece 24 and the 3rd locating piece 25 is provided with in another side edge of the backboard of the side relative to arc-shaped.The line of the central point of the first locating piece 23, second locating piece 24 and the 3rd locating piece 25 forms a firmly triangle, backboard 3 is located in a mold, just making red needle 12 can not offset when going out aperture 31 without the need to manually locating, reducing labour intensity, increase work efficiency and quality, reduction production cost and scrappage also eliminate potential safety hazard simultaneously.

Embodiment three:

As Fig. 4, shown in embodiment three in the technique described in embodiment one second step indentation print 32 impressing mould, comprise be provided with print pin 15 patrix 1, coordinate the counterdie 2 placing backboard 3 with patrix 1; Counterdie 2 is provided with the three-point fix structure coordinated with this backboard 3, and all the other structures are with the punching die described in embodiment two.

In the mould described in embodiment two and embodiment three, upper mould fixed plate 14 and counterdie backing plate 22 can be separately fixed on the pressing equipment such as punch press or hydraulic press.

The explanation of above embodiment just understands core concept of the present invention for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications.

In sum, the present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
