Abstract
The paper presents the results of an experimental study of the pipe extrusion process using the method of coordinate grids. The estimation of influence of separate conditions of friction on the contact surfaces of the deformable material and the pressing tool on metal flow pattern. The calculation of the forming operation is made for extrusion process stages.
Highlights
The paper presents the results of an experimental study of the pipe extrusion process using the method of coordinate grids
As it is shown in works (Starostin & Kargin, 1983; Osadchy & Kolikov, 2012), qualitative characteristics of extruded pipes depend on a number of technological parameters
The coordinate grid method (CGM) (Del & Novikov, 1979; Kargin & Kargin, 2011) can help justify the choice of boundaries of plastic deformation applied in case of mathematical description of the pipe extrusion process
Summary
As it is shown in works (Starostin & Kargin, 1983; Osadchy & Kolikov, 2012), qualitative characteristics of extruded pipes depend on a number of technological parameters. Among them a strain capacity of a work material (Barichko, Kosmatskiy, & Rushchits, 2013; Kosmatskiy, Barichko, & Voskhodov, 2014; Barichko, Kosmatskiy, & Akhmedyanov, 2015; Kosmatskiy, Fokin, & Filyaeva, 2016) and friction conditions on contact surfaces, i.e. a deformed metal – a pressing tool (Manegin & Anisimova, 1978) should be singled out. An experimental study of the influence of friction conditions on the pattern of metal flow when pressing pattern pipes can ensure in the initial approximation the formation of a scientific and technology-based approach to selection of lubricants during the pipe extrusion. The choice in favour of CGM is justified by the fact that when using it is possible to consider each element of the coordinate grid as an element of the metal flow nucleus undergoing homogeneous strain during the deformation process (Gubkin, 1960)
