Abstract
The paper presents theoretical studies of a new deformation process combining the stages of equalchannel angular pressing (ECAP) and the Linex scheme.To analyse the resulting deformation forces, the stages of pressing in a matrix and compression by a chain conveyor are separately considered.Equations were provided for determining the forces acting on the drive pulley, ECA matrix, and chain element link.A trial calculation and comparative analysis with the previously known rolling-ECAP process showed that the new ECAP-Linex process allows for a stable deformation process with lower forces and a smaller channel junction angle in the matrix.The values obtained by equations are verified with computer simulation using the finite element method in the Deform program.A comparison of values showed that the force values in the calculation and simulation have a high level of convergence.For all three considered parameters, the difference value did not exceed 3%.
