[0002] Small batch prototype trial production is an important process for design verification and improvement of related product structure design, benchmark strategy, part tolerance, and process plan in the early stage of the body-in-white vehicle development process. As the requirements for vehicle development become higher and higher, and the structure of product replacement is getting faster and faster, in order to reduce the occurrence of major problems in the later stage and shorten the cycle of related test certification, more and more OEMs are conducting trial body development in the early stage of new car development. There are more and more trial production projects of covering parts represented by fenders, side panels, and four-door two-covers, and a large number of parts manufacturing companies specializing in trial body development have been born.

[0003] The fender itself has a complex parts structure. The hood matching side, headlight matching side, and front door matching side generally have negative angle flanging or shaping features, which require special wedges for side flanging or side shaping operations, and in most cases cannot be completed in the same process, resulting in a large number of mold opening processes for trial fenders. The same fender has different overlapping parts. Due to the limitations of the product structure, the trial stamping fender forming requires multiple side flipping and side shaping to achieve the product shape characteristics. The forming process of the fender of the trial model is generally: drawing → laser cutting → positive shaping + side shaping → side shaping → laser cutting. Some fenders even require 3-sided side shaping, and in theory, multiple sets of side shaping molds need to be developed; each trial fender project needs to develop all drawing and side shaping processes for fender parts, which requires large personnel investment and large design workload; each trial fender project needs to develop all drawing and side shaping processes for fender parts, which requires large personnel investment and large design workload.

When the fender is shaped, the common upper die base 1 presses the conformable pressure plate 5 and the common inclined wedge 2 downward. The common inclined wedge 2 is affected by the inclined surface of the common lower die base 3, so that the conformable side whole knife block 4 exerts force obliquely downward to process the fender sandwiched in the middle.
