Problems solved by technology

Use two sets of molds to punch and flang the workpiece respectively, the obvious disadvantage is that the production cost of the workpiece is increased
Moreover, due to the use of two processes, positioning problems are bound to be involved in each process, and the two positionings will inevitably lead to a decrease in the precision of the workpiece processing

Embodiment Construction

[0010] refer to figure 1 , figure 1 A best embodiment of the double-action compound die for flanging and punching of the present invention is described. It also shows the working status of the mold before flanging and punching. The double-action compound die for flanging and punching includes a punching punch 4 and a punching die 5 respectively arranged on the end face between the upper die base 1 and the lower die base 2 . On the upper and lower end surfaces between the upper die base 1 and the lower die base 2, at least one punching punch 4 and punching die 5 are arranged respectively. On the inner side of the inner cavity of the lower end surface of the upper mold base 1, a wedge driving surface 11 is provided with an inclination angle consistent with that of the wedge surface on the outside of the wedge slider 7. The upward-moving wedge slider 8 located above the inner wedge surface of the wedge slider 7 is also provided with a wedge driving surface 12 whose inclination...

Abstract

The invention discloses a flanging and punching double acting composite die, which aims at providing a composite die which can realize the punching and upward flanging of a work piece in a working procedure so as to improve production efficiency, and reduce manufacturing cost. The key points of the technical proposal are that an upper die base(1) is provided with a tapered wedge driving face(11) which can downward push the outer tapered wedge face of a tapered wedge slide block(7) to make horizontal movement toward the center of a lower die base(2); and an upward movement tapered wedge slide block(8) is arranged above the inner tapered wedge face of the tapered wedge slide block(7); driven by the tapered wedge active force of the upward movement tapered wedge slide block, the upward movement tapered wedge slide block drives a flanging embedded block(6) in a gap on the upper end thereof to move upward together, a pressing piece arranged below a pressing-material machine(3) is upward flanged, at the same time, a punching concave die(4) arranged on the upper die base(1) and a punching concave die(5) arranged on the lower die base(2) punch the work piece.

Description

technical field [0001] The invention relates to a composite die for punching and flanging. Background technique [0002] In the prior art, when punching and flanging up are performed on the same workpiece, two processes, the punching process and the flanging up process, are usually required. Therefore, two sets of molds are often required, namely the punching mold and the flanging mold. Use two sets of molds to carry out punching and flanging to the workpiece respectively, and its obvious disadvantage is that the production cost of the workpiece is increased. Moreover, due to the use of two processes, positioning problems are bound to be involved in each process, and the two positionings will inevitably lead to a decrease in the precision of the workpiece processing. Contents of the invention [0003] The task of the present invention is to propose a composite mold that can improve production efficiency, reduce manufacturing cost, and can simultaneously complete punching...
