Side-flanging die structure

Abstract

The invention discloses a side-flanging die mechanism. A material pressing core and a fixed lower die are compounded to form a product and keep a clamping state. A to-be-flanged area of the product protrudes to the exterior of a forming area of the material pressing core and the fixed lower die. A driving block and a sliding slanting wedge are matched correspondingly and arranged relative to the to-be-flanged area of the product. The sliding slanting wedge is connected with a flanging cutter. The junction line between the to-be-flanged area and the forming surface of the product is located on the side face, close to the fixed lower die, of the flanging cutter and is always on an advancing route of the side face. The driving block is pressed down to abut against the sliding slanting wedge to make relative slipping, and produced slanting cutting force pushes the sliding slanting wedge to move in the horizontal direction far from the fixed lower die. The sliding slanting wedge drives the flanging cutter to complete the side flanging action of the to-be-flanged area. The sliding slanting wedge drives the flanging cutter to move in the horizontal direction far from the fixed lower die, namely, the to-be-flanged area is subjected to horizontal side flanging from inside to outside, the stamping process is simplified, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of stamping dies for auto parts, in particular to a side flanging die mechanism. Background technique [0002] Automobile panel flanging refers to a stamping process that turns the edge of the hole and the outer edge of the part into a vertical wall under the action of the mold. In the prior art, the traditional process of flanging from the outside is usually used. The mold structure of this traditional process is complicated, and it usually conflicts with other process contents during the processing. If it is necessary to adjust the part and increase the mold fit, it is often Need to increase the process. The rapid development of the automobile industry is closely related to cost reduction. From the perspective of stamping technology, the traditional process method is more complicated, and the mold structure is complex, the cost is high, and the processing efficiency is low.
