Obtaining Body Parts with Variable Wall Thickness Along the Perimeter

The article considers the production of housing parts with variable wall thickness along the perimeter. The use of this type of products is possible for various areas of industrial development, as the most important branch of the national economy. Examples of the use of cylindrical body parts of variable thickness in the electrical industry are given. The technological process of manufacturing body parts with variable wall thickness along the perimeter of sheet blanks consists of the operation of drawing without thinning and the operation of drawing with thinning and end support, as well as direct extrusion. The simulation of the described operations is carried out, the process diagrams and the semi-finished product obtained as a result of forming a round sheet billet are shown. The power modes of the first and second operations of the technological process of manufacturing body parts with variable wall thickness along the perimeter from sheet blanks are studied. Recommendations are given for the manufacture of body parts with and without a flange. The technological process of manufacturing body parts with variable wall thickness along the perimeter from sheet blanks presented in the article ensures high quality of products while saving material and energy resources, and also leads to a reduction in labor costs.
