“…An effective artificial intelligence technique is applied to automatically design the multi-pass cold drawing processes [18]. The production process of Z-shaped wires was studied by Fontanari et al [19]. Wang and Argyropoulos investigated a single-step wire drawing technique for section rods from round bars [20].…”

Trapezoidal-shaped aluminium wires are in demand for the production of the aluminium conductor steel supported/trapezoidal wire (ACSS/TW) conductor. In this work, it is proposed to manufacture such wires by a multipass cold drawing process using a series of shaped dies with an initial aluminium wire, which has an outer diameter of 9.5 mm. The ruled surface partition method is introduced to design the intermediate die profile of the multi-pass cold drawing. It is possible to design the intermediate die profile efficiently according to the suggested reduction ratio and save time regardless of the geometric complexity. A multi-pass drawing machine and a universal testing machine are both used to investigate the drawing process of trapezoidal-shaped aluminium wires. Wire break occurs when a five-pass drawing process is introduced. The six-pass drawing process is suggested to apply in a consideration of die cost. The final production has a good surface finish and a dimensional accuracy, suitable for the production of the ACSS/TW conductor. A finite element method (FEM) simulation approach is used to analyse stress and drawing force for the proposed process. The Von Mises stress values gradually increases and the drawing force values decrease along the pass schedule. The influence of the number of the drawing passes is numerically assessed. The drawing force value and the Von Mises stress value are lower when the number of dies is larger. The numerical compute drawing force of the six-pass drawing process is compared with the experimental ones. A good agreement between the predicted and experimental results can be observed.

“…The shaped wire, a kind of steel wire with non-circular section, is an important branch of metal products [1]. According to the different shapes of the cross-section, its production method can be divided into die-drawing, roller-drawing and rolling which is a deformation progress of two or four-roller rolling [2]. Experimental and theoretical researches have confirmed that the distribution of the stress, deformation and displacement speed of metal along the height and the width of the section were uneven during the rolling process of the shaped wire, at the same time, the deformation extended to the outer area adjacent to the geometric deformation zone [3,4].…”

Based on the deformation features in the rolling process of shaped wires, this paper focuses on the metal flow rules and distribution characteristics of stress and strain through simulating the shaping process by DEFORM-3D. The equivalent stress and equivalent strain is in the same distribution: smallest on the base and gradually increasing along the broadening direction and highest on the tooth. A satisfactory concordance between the scattering of the hardness values measured over the wire sections and that of the equivalent strain is found, thus verifying the accuracy and the reasonableness of the simulation process.
