Abstract

It is possible to achieve modernization and the increase in stability of performing the process of plastic forming by experimental research and analysis of experimental results. Justification of new technologies application, such as the process of tube hydroforming, can be seen through the quality and price of products, as well as productivity and flexibility of production. A die is essential to the performance of the process of plastic forming, which is why it is necessary to minimize its load. This would increase die life, stability and quality of process performance. The overall costs of the process performance would be reduced by the share of the costs related to the die. Taking into account the impact of certain parameters on die in the process of hydroforming, such as the pressure of the fluid inside the tube, the size of the displacement of the axial punch, as well as intensity of pre-clamping force of screws, the force on die clamping screws that occurs in the forming process is modeled in the paper. The values of the input parameters of the process, as well as the load of the screws for die clamping in the process of cross tube hydroforming, have been measured experimentally.
