Abstract

In hydrostatic forming, technological parameters have a significant influence on the thin shell product formation. One of the most important factors is the forming liquid pressure. This pressure exerts directly on the workpiece, pulling the workpiece closely to the die's profile. Therefore, this parameter should be kept large enough for shaping the product with the required shape and size. In practice, however, it is very difficult to achieve and maintain the high value of this parameter. In addition, it is also necessary to set up a mathematical model of this parameter to support the calculation and control. This paper has suggested a simple solution for maintaining fluid pressure during forming. The solution has been applied into the experimental system. Using this system to investigate forming liquid pressure parameter, the paper has given a suitable mathematical model when shaping cylindrical details from sheet metal. The results of the study contribute to data in die design, parameter calculation and control as well as forming process stabilization in hydrostatic forming for sheet metal.
