Embodiment Construction

[0020] Such as figure 1 As shown, it is an existing mold for performing upper flanging operation on the sheet material. The flanging knife block is fixed on the lower mold base, and the flanging pressing plate 113 is arranged on the lower mold base through a spring, and the upper mold base and the flanging pressing material A flanging lower mold cutter block 110 is arranged between the plates 113. During operation, the upper die base drives the flanging pressing plate to move downwards, so that the flanging cutter block performs flanging processing on the sheet material. Such as figure 2 As shown, it is an existing die for punching sheet metal. The punch is fixed on the upper die base through the punch fixing plate, and the pressing plate is set on the upper die base. When working, the plate is firstly positioned. The upper die base moves downward, driving the punch to move downward, the clamping plate presses the plate, and the punch passes through the plate to complete the...

Abstract

The invention discloses a piercing and flanging compound die, which comprises an upper die holder and a lower die holder. The upper die holder is provided with a pressure plate and a punch, the lower die holder is provided with a lower die cutter block matched with the punch and provided with a fixed seat, a flanging cutter block driver capable of moving vertically is arranged between the fixed seat and the lower die holder and is provided with a flanging cutter block, and a rocker mechanism for driving the flanging cutter block driver to move vertically is arranged on the fixed seat. The compound die can be used for piercing and flanging the same workpiece simultaneously once the workpiece is positioned, so that production precision and efficiency of the workpiece can be improved greatly. Besides, the compound die can be switched into a flanging work state or a piercing work state according to production requirements, and accordingly has wider application.

Description

technical field [0001] The invention relates to a punching and flanging composite mold, in particular to a punching and flanging composite mold which can simultaneously complete flanging and punching on the same workpiece in a set of molds and can be switched. Background technique [0002] At present, when flanging and punching are performed on the same part, two sets of molds are usually required to complete it, which obviously increases the production cost of the part and the manufacturing cost of the mold. Precision and efficiency of production. [0003] If punching and flanging are performed on automobile panels, it is necessary to pass such as figure 1 The mold shown is for flanging processing. Its structure is that the flanging cutter block is fixed on the lower die base, and the pressing plate is set on the lower die base through a spring. When working, the upper die base drives the pressing plate to move downward, so that the turning The side knife block is used to...
