Technical Field

Background

The press bending forming of the stamping equipment is an important product bending forming process. The press bending forming belongs to one-step forming, a profiling mold corresponding to an arc-shaped profile of a product piece needs to be manufactured, and meanwhile, the problem of resilience of the product piece after press bending is fully considered, and the profile of the mold is designed in a matching mode. This presents two problems: firstly, the profile design difficulty of the profiling mold is high, and the repair workload is large. The press bending forming is a complex plastic deformation process, the accurate pre-judgment of the springback value is very difficult, and the actual contour of the die can be determined only after multiple trial-manufacturing and die repairing are carried out by combining the experience of designers. If the radian of the product is greatly changed, the original mold cannot be used, and only a new mold can be cast. Secondly, the dependence on incoming material quality stability is high. The fluctuation of the cross section shape of the incoming material of the product piece and the fluctuation of the material performance can obviously influence the bending forming rebound amount, and particularly, the large fluctuation of the material performance among batches is a common phenomenon of the aluminum alloy extruded section. These problems are difficult to flexibly deal with for the traditional press bending die, and generally can only provide too severe quality requirements for upstream incoming materials, and increase the production cost of the incoming materials. In addition, the profiling mold can only be used for profiling one product piece, and has no universality for product pieces with different specifications and different profiles. In view of this, it is necessary to design a press bending apparatus with wide applicability and flexible operation.
