目前采用金属模进行压力成形,尚有很多难于解决的问题,诸如减少生产工序数;降低金属模的制造成本;复杂形状制品的成形;不损伤制品的表面;控制板厚的局部减小;降低原材料的等级;适合多品种、小批量生产等。上述问题采用一般传统的成形法解决是困难的,因此,对向液压成形法的应用即被重视。 Currently, the use of metal molds for pressure forming has many difficult problems to be solved, such as reducing the number of manufacturing processes, reducing the manufacturing cost of metal molds, forming of complex shaped products, not damaging the surface of the products, controlling the local reduction of the thickness of the sheet, The level of raw materials; suitable for more varieties, small batch production. The above problems are generally difficult to solve by the conventional forming method. Therefore, the application of the forming hydroforming method is emphasized.
