Abstract
Current article presents 90 degrees two-angle bending new process chart with usage of tool with elastic bars. Tool design allows considering elastic blank’s springback to get more precise bending radius. Usage of elastic bars makes two-angle bending process more producible and costless as there no need to make additional operations of geometry defects correction. In that article, bending technological parameters are determined. Strain-stress blank’s conditions during processing is describe. Analytical calculations are made and elastic bar sizes for different blank material are demonstrated.

Summary
Two-angle sheet metal bending is a result of plastoelastic deformation. Because of elastic deformations during bending process, material springsback. Springback angle size depends of material elastic properties, thickness, value of deformation, angle and bending method [3]. In the article we present a tool with elastic bar design that allows to make 90 degrees two-angle bending process more producible and costless [4]. All time during process bars tighten blank to punch, and as a result, that compensates springback effect (figure 1). 1 – punch; 2 – elastic bar; 3 – blank; 4 – ejector with buffer; 5 – matrix; β – springback angles Fig. 1.
