随着科学技术的不断发展,机械制造工艺对各种机械、仪表中占有相当大比重的金属薄板冲压件提出了一些新的课题。最近出现的薄壁件高能成形法、各种提高板料成形中变形率的加工方法以及适合于中小批生产的组合冲压工艺方法等的出现,正是这些新要求的反映。一、高能成形法近来由于火箭、导弹技术的发展,要求解决一些大
With the continuous development of science and technology, mechanical manufacturing process for a variety of machinery, instruments account for a large proportion of sheet metal stamping put forward some new topics. The recent emergence of thin-walled high-energy forming method, a variety of processing methods to improve the deformation rate of sheet metal forming and stamping process suitable for small and medium-sized batch production process, etc., is the reflection of these new requirements. First, the high-energy forming method Recently, due to the development of rockets and missiles, some big solutions are required
