ANALYSIS OF THE POSSIBILITY OF SIMULTANEOUS DISTRIBUTION WITH THE FORMATION OF A BENT EDGE SECTION
Many operations can be carried out with pipe blanks, the most common of which are expansion, crimping, bending, flanging, upsetting. However, a combination of these operations is also possible. Thus, it is possible to implement the process of expanding the pipe with the simultaneous formation of a bent edge section. However, such an operation is very complex, since there is a large combination of punch angles, bending radius, wall thickness and workpiece material. Therefore, the formation of a bent edge section requires a comprehensive comprehensive analysis, which is carried out using computer simulation. The question is raised whether it is possible to carry out both expansion and bending of the edge part of the pipe at the same time using plastic forming with a profile punch. The paper analyzes the possibility of forming the required surface from an aluminum tubular billet. The images of the obtained part, graphs of the technological force and the scheme of distribution of the intensity of deformations in the workpiece are given. Based on these parameters, the operation is analyzed and certain conclusions related to further research are made.
