Described die of beating comprises dozen concave-convex mold and beats concavo-concave mould, beat concave-convex mold outer rim to mate with the lamellar body outer rim of reserved finger hole position, beat and concavo-concave mould is provided with and beats concave-convex mold outer rim and mate groove, beat concave-convex mold and beat concavo-concave mould and coordinate, finger hole depressed area is pressed into the lamellar body of the reserved finger hole position of draw ring;
Described pre-curled mould comprises pre-roll patrix and pre-roll counterdie, and pre-roll patrix edge is provided with pressure angle, pre-roll counterdie is provided with finger hole depressed area slot to make way, and pre-roll patrix and the cooperation of pre-roll counterdie are pressed into chamfering to the draw ring outward flange be cut into through edger;
Described groove mould comprises groove patrix and groove counterdie, groove patrix is provided with the groove blade mated with outer peripheral edge, finger hole depressed area, groove patrix and groove counterdie coordinate, to successively through the finger hole depressed area groove of the shaping RPT draw ring of flange die, shaping mould, formed with RPT draw ring one but can tear along groove stay sheet.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
The pellet material in finger hole region can be retained by this mould, both can increase the entire area of tab body, can the region retained be used, such as when the packing of product again, namely can stay at reserve area and sheet print LOGO, carve characters, for client provides products propaganda mode; By this reserve area is carried out beat recessed, processing line of weakness, realize the shaping of finger hole, do not affect the use of draw ring.
As preferably, the further technical scheme of the present invention is:
The described curved knife blade arc length cutting punch accounts for 1/3 of finger hole girth.
Described concave-convex mold outer rim of beating is oval outer rim, and the described groove beaten on concavo-concave mould is oval-shaped groove.
The groove blade of described groove patrix is oval blade, and the finger hole of formation is level and smooth, mellow and full slotted eye.
