Technological foundations of reducing the number of stages in the forming operations of drawing, reducing and bulging

Деталі, які отримані обтиском

Developed new technological foundations of obtaining the hollow articles by forming cold sheet stamping processes, including drawing, reducing and bulging. The novelty lies in the development of new methods of drawing, reducing and bulging, to create and use a special profiles deforming tool. Using this deforming tool provides a significant reduction of friction influence in the forming of articles, reduce deformation force and increase the degree of deformation in one stage.
