Problems solved by technology

At present, many automobile body panels have a " " type of flanging structure. The stamping process of this flanging structure includes two processes of vertical flanging and side flanging, which need to be completed by two sets of molds and stamping equipment. It not only increases the cost of mold development and equipment purchase, but also has repeated operation steps in workpiece installation and equipment debugging, which affects the improvement of production efficiency

Abstract

The invention discloses a composite flanging mechanism of a stamping die. The mechanism is used for implementing one-time stamping forming of 'transverse U' shaped flanges of workpieces. The mechanism comprises a vertical flanging part, a side flanging part, a pressing device, an upper die holder and a lower die holder. The mechanism is characterized in that: a vertical flanging die and a side flanging die are combined together and share a set of pressing device, and the vertical flanging part is arranged between the pressing device and the side flanging part. Stamping forming of a 'transverse U' shaped flange structure is independently finished by one set of die, so that the manufacturing cost of a product is effectively reduced; and repeated installation and operation steps in the conventional machining method are reduced, so that the production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a flanging and forming mechanism for steel plate parts, especially suitable for a plate stamping die combining vertical flanging and side flanging, and belongs to the technical field of metal stamping. Background technique [0002] With the continuous advancement of automobile manufacturing technology, consumers pay more and more attention to the appearance quality of the vehicle. On the one hand, in order to obtain a continuous and smooth visual effect, the molding of automobile body panels is mostly realized through die stamping technology; on the other hand, On the one hand, in order to meet the requirements of vehicle styling, the structure of body panels tends to become more complex. At present, many automobile body panels have a " " type of flanging structure. The stamping process of this flanging structure includes two processes of vertical flanging and side flanging, which need to be completed by two sets of molds and s...
