A kind of lifting sheet-metal part blanking units, comprises base plate, punch and die, also comprises flexible kink, cylinder, guide rod, guide pin bushing and convex mould base, and described cylinder is positioned on top board, and the piston of cylinder is connected with convex mould base middle part; Described flexible kink, guide rod is all fixed on that side away from charging aperture on base plate; Top board lower surface is fixed on described flexible kink top; Described guide rod is fixed through top board and with nut; Described guide pin bushing is enclosed within on guide rod, and is connected with convex mould base two ends; In described guide pin bushing, be also provided with ball; Described punch is fixed on convex mould base below, and lower surface be shaped as taper.
Preferably, described flexible kink has two, is distributed in the both sides of base plate.
Preferably, the cone angle of the described tapered part in punch lower surface is 40 ° ~ 60 °.
More preferably, the cone angle of the described tapered part in punch lower surface is 60 °.
Preferably, described guide rod has 2 ~ 4, is uniformly distributed on base plate.
Preferably, the material of the tapered part in lower surface of described punch is 45# steel.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) in the utility model, cylinder is positioned on top board, and the piston of cylinder is connected with convex mould base middle part; Guide rod is positioned at base plate that side away from charging aperture, and top is through top board; Guide pin bushing is enclosed within on guide rod, and is connected with convex mould base two ends, can increase the stability of die-cut frock, avoids punched discontinuity phenomenon, thereby guarantees product quality.
(2) the utility model is provided with flexible kink, and that side away from charging aperture on base plate is fixed in bottom, and top board lower surface is fixed on top, the flexible kink of increase can be realized the lifting of whole die-cut frock, thereby the problem that the collapsing length that has solved cylinder piston is limited, practicality is wider.
