Cold drawing of regular polygonal tubular sections from round tubes

A Review on Spring Back and Optimization Process

“…Bayoumi obtained the analytical solution for the problem of cold drawing through flat idle rolls of regular polygon metal tubular section from round tube [1] Rajput and Victor were learned the effect of various parameters like die entry angle, coefficient of friction and cross section reduction of the tube with a 3D model of seamless cold drawing process using ABAQUS 6.10. Simulations were carried out comprising of different levels of die entry angle, cross section reduction and comprising of different levels of die entry angle, coefficient of friction.…”

Determination of the forming tool load in plastic shaping of a round tube into a square tubular section

“…(16) and (17); the results obtained are compared to the results obtained from the previous work by Bayoumi (2001) in Tables 2 and 3, respectively. On comparing the results in Tables 2 and 3; it is found that the predicted roll loads obtained from Eq.…”

“…The shaping into a square section is a plastic metal shaping process that has been investigated by several workers. Bayoumi (2001) presented an analytical solution for cold drawing of a round tube through flat idle rolls to produce a regular polygonal metal tubular section. A velocity field has been obtained from kinematics considerations to yield the strain-rate components.…”

An upper bound analysis for reshaping thick tubes to polygonal cross-section tubes through multistage roll forming process

“…They also reported their work on reshaping of no-circular pipes, [6]. In an analytical work by Bayoumi [7] a solution was obtained for the problem of cold drawing through flat idle rolls of regular polygonal metal tubular sections from round tube. Bayoumi also gave an analytical solution for the problem of cold flattening of a round tube into an oblong shape through rolling between two flat rolls [8].…”
