For achieving the above object, the utility model is by the following technical solutions:

The drift punching die of the first scheme that the utility model adopts, be respectively die shank, upper die and lower die and base from top to bottom, wherein die shank is fixed on patrix; Described patrix is provided with drift rotating disk, and is fixed on upper bolster by patrix rotating shaft, and upper bolster edge is provided with at least one punch press guide pin bushing; Wherein, drift rotating disk is provided with at least two drifts; Described counterdie is fixed on base by die shoe, and die shoe is provided with the punching rotating disk matched with drift rotating disk, and is fixedly connected with die shoe by counterdie rotating shaft; Die shoe edge is provided with the guide pillar that can mutually engage with punch press guide pin bushing.In said structure, drift rotating disk is provided with at least two punch structures, can avoiding the more mold exchange when processing different workpieces, therefore simplifying procedures, and saves the operating time, enhance production progress.

The drift punching die of the alternative plan that the utility model adopts, on the basis of first scheme, in order to meet difformity mould produce needs, different shapes is arranged at drift top, can preferably be set in circle, ellipse, regular polygon any two or more.In said structure, more mold exchange can not only to be avoided in workpiece process ceaselessly, and the needs of difform punching in production can be met, thus simplify procedures, shorten process time.

The drift punching die of the third program that the utility model adopts, first or alternative plan basis on, be at least provided with one at the edge of drift rotating disk and/or punching rotating disk and turn hole, wherein, what drift rotating disk was corresponding is that patrix turns hole, and what punching rotating disk was corresponding is that counterdie turns hole.In the structure that this programme adopts, the instruments such as iron can be inserted and turn in hole, rotate drift rotating disk or punching rotating disk, thus need adjustment according to processing or select different drifts.

The drift punching die of the third program that the utility model adopts, on the basis of above either a program, is arranged to ratchet structure by patrix rotating shaft further, thus facilitates the adjustment of drift rotating disk, and can determine disk position.

The drift punching die of the fourth program that the utility model adopts, on the basis of above either a program, arranges through hole in the base, thus the workpiece after convenient processing automatically falls from through hole.

beneficial effect

Compared with prior art, the utility model has the following advantages:

(1) drift punching die described in the utility model is provided with drift rotating disk and supporting punching rotating disk, by rotating, the drift supporting with workpiece to be processed selected by rotating disk, punching is processed, without the need to more mold exchange in process, thus avoid bring because of more mold exchange troublesome operation and the problem such as location is inaccurate;

(2) the drift rotating disk of drift punching die described in the utility model is connected with upper bolster by rotating shaft, and ratchet structure is arranged in rotating shaft, thus facilitates the adjustment of drift rotating disk, and can determine disk position;

(3) the disk edge place of drift punching die described in the utility model is provided with and turns hole, and the turning tools such as iron can conveniently insert wherein by this structure, thus rotate rotating disk, according to processing needs, selects different drift;

(4) base of drift punching die described in the utility model is middle is provided with through hole, can be convenient to the workpiece after processing and automatically therefrom fall, improve working (machining) efficiency.
