THE BILLET PROFILE CROSS SECTION DISTORTION IN THE PROCESS OF ITS FORMING ON THE STRETCH-BENDING EQUIPMENT
In the operations of forming profile billets on stretch forming method is often a problem of distortion of the cross section in the process of loading of the billet. To properly design the tools and technology to develop a profile forming billets on the bend-stretching equipment is required at the design stage of technological process to predict the behavior of the billet in the process of its formation. In this paper, we propose to use the mathematical modeling of the process of forming a profile billet on the bend-stretching equipment to assess the distortion of profile cross section and development of technology provides the necessary accuracy
