Abstract
Possibility of unification property realization in application to variants of structural-technological solutions of “metal+composite” joints.It is drawn that this property is important for up-today vehicle engineering structures at different goals of its manufacturing. It is shown that there are three possible options can be revealed in metal-composite heterogenous joints realization: with monolithic, cylindrical and sheet transversal fastening connections.Possibility of application sheet transversal fastening elements produced on metal strips is considered exactly. Also, possibility of implementation strips of different materials and thickness is analyzed.The property of unification is most fully manifested at the stages of design, technological preparation of production and production itself. Variants of technological processes for manufacturing sheet fasteners on metal strips using stamping methods or laser cutting are proposed. An analysis of the advantages and disadvantages of these technical processes showed that the most rational method is stamping with bending.Options for route technical processes for forming transversal connections on metal tips using sheet reinforcing elements are proposed.Options for equipment are proposed, with the help of which serial production of teeth on metal strips is possible. It should be noted among these equipment options metal stamps for stamping teeth and using an electro-hydraulic device for bending them.Examples of implementation of design and technological solutions with sheet micro-elements in the manufacture of high-pressure vessels and in the strengthening of bolted joints are given.
