Design of bending tools and templates for sheet metal parts used in mechanical engineering

Abstract

Due to the high demand for sheet metal parts in aviation and other branches of mechanical engineering, as well as an increase in their production volumes, the design of bending tools and templates has become relevant. For an example of design, a typical part in mechanical engineering was taken – the diaphragm. Four templates and two mandrels with clamps were designed, such as: a part scan template, a different template, an internal contour template and mandrels with clamps of the first and second transition. The individual features in the design of templates and mandrels for bending are considered. The article presents several ways to calculate the sweep: calculation using formulas and 3d modeling of the sweep of a part. The spring of the part is taken into account when designing the mandrels and calculated in several ways: mathematical, tabular and experimental.
