“…The experimental results only permit to determine macroscopic data, but failure criteria calculation needs the local strain and stress fields to be evaluated. These fields can be evaluated by means of FEM (Palengat et al, 2013;Beland et al, 2011).…”

“…To avoid fracture occurring at the die exit, the drawing stress applied to the drawn section at the die exit must remain within a safety margin below the ultimate tensile stress of the drawn material. The axial stress in the drawn tube is therefore the main limitation for drawing as shown by Béland et al (2011). Bui et al (2011) determined the drawing limit of AA6063 tube using a 5°halfangle conical mandrel.…”

Tube drawing with a fixed plug is investigated experimentally and numerically in order to optimise an industrial pass sequence. Tube drawings are performed on a laboratory drawing bench equipped with force, displacement and temperature sensors. The drawing limit of 316 LVM stainless steel (SS) tubes is determined by varying the plug position and the effect of lubricant is discussed. The numerical model relies on the precise die geometry measured using a contact method and on the mechanical behaviour of SS 316 LVM characterised by tensile tests between 20°C and 200°C on annealed tubes. The friction coefficients between tube and die and tube and plug are determined by FE modelling by comparing measured and simulated plug, die and drawing forces. The use of a solid lubricant together with the lubricating oil prevents stick and slip and lowers the friction coefficients. Friction is further decreased by preheating the die. The identified friction coefficients are discussed in terms of the classic Stribeck friction curves and lubrication is found to be in the hydrodynamic regime.

“…The study showed that both the length and shape of bearing channel depend on the drawing force with conventional tooling [2]. In another study, Beland et al [3] used LS-DYNA to determine optimization of tool geometry for reducing stress level for 6063 T4 by a sinker die, a drawing die, and cylindrical plug. The study reveals that three tubes can be drawn at the same time up to maximum length of 12 m at different tube diameters and wall thicknesses.…”

ÖZBu çalışmada, sonlu elemanlar analizi kullanılarak, sabit mandrel ile soğuk boru çekme işleminin benzetimi yapılmış olup, kesit daralma oranının, yarı kalıp açısının, yarı mandrel açısının ve sürtünme katsayılarının çekme gerilmesine etkileri araştırılmıştır. Sonlu elemenlar modeli, %16 kesit daralmasındaki deneysel verilerle doğrulanmıştır. Netice olarak, yarı kalıp açısının plastik şekil değişimine etkisi yarı mandrel açısından daha büyük olmuştur. Sebebi ise kalıp açısının büyüklüğünden kaynaklanmaktadır. 12 o 'lik yarı kalıp açısı bütün sürtünme değerleri için minumum çekme gerilmesini vermektedir. Sabit konik mandrel ile boru çekme işleminde 7 o 'lik yarı kalıp açısı için 2-4 o aralığındaki yarı mandrel açısı kullanılmalıdır. Deneysel ve sonlu elemanlar analiz sonuçlarının uyum içinde olduğu görülmüştür.Anahtar Kelimeler: Soğuk boru çekme, Sonlu eleman analizi (FEA), çekme gerilmesi, yarı kalıp açısı, yarı mandrel açısı Effect of the process parameters on cold tube drawing with a fixed plug using finite element analysis for AISI 1010 steel ABSTRACTIn this present work, finite element analysis (FEA) is applied to simulate cold tube drawing process with a fixed plug for AISI 1010 steel tube. The effects of reduction of area, semi die angle, semi plug angle, and friction coefficient on drawing stress are studied. The finite element model is successfully validated with the experimental data at reduction of area 16%. Results indicate that a good agreement between the experimental and the finite element analysis (FEA) is found. Consequently, the effect of semi die angle on plastic deformation is larger than the semi plug angle because of the bigger size of the semi die angle. Semi die angle of 12° gives minimum drawing stress for all coefficient of frictions. A semi plug angle between 2° and 4° should be used in tube drawing process with a conical fixed plug when semi die angle is equal to 7 o .
