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...

The invention discloses a punching and flanging compound die, which comprises an upper die base and a lower die base, the upper die base is provided with a binder plate and a punch, and the lower die base is provided with a punch The matching lower die block; the lower die base is provided with a fixed seat, and a flanging knife block drive block that can move up and down is provided between the fixed seat and the lower die base. A flanging knife block is provided on the driving block of the flanging knife block; a rocker mechanism for driving the flanging knife block driving block to move up and down is arranged on the fixed seat. The mold can complete the flanging and punching work on the same part at the same time, and it only needs to be positioned once, which greatly improves the production accuracy and efficiency of the part; and because the composite mold can realize the production needs Switching to only flanging or punching work makes the composite mold more versatile.
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...
