Modelling and control of dieless wire drawing.
<p>A novel technique of drawing wire, i.e., dieless wire drawing, is described in which no conventional reduction dies are used. The wire is passed through a unit having stepped parallel bores filled with polymer melts, the smallest bore diameter being greater than the initial nominal wire …

Addressing equipment set-up time and manufacturing cost through real time inline inspection in tantalum wire manufacturing
For this study, a novel wire inspection system was developed to detect surface defects and monitor diameter real-time during the final wire drawing operation. Throughout his work, it was proven that the new inspection system was able to catch common wire defects under manufacturing conditions (wire …

Microstructure-strength relationship of a deformation-processed aluminum-magnesium composite
… deformation processed by extrusion, swaging and wire drawing. Two compositions, Al-13vol%Mg and Al-20vol%Mg were used to compare the influence of second phase content. The microstructure of the composites was convoluted, ribbon-shaped second phase Mg filaments in Al matrix, which resulted from …

A Study of the Application of Low Frequency Oscillations to Multi-Tool Drawing Processes
… ‘axial vibrations (O to 100 Hz) to the tandem wire and fixed plug tube drawing processes. The investigation was conducted on a 2000 lbf horizontal bull block, the tools being oscillated by two electrohydraulic vibrators, Mild steel wire and medium carbon steel tube were selected for the …

Computer integrated manufacture of complex dies for drawing n-circular wires.
… is based on the idea of machining complex wire drawing die configurations that require drastically different shapes on the top and bottom die faces, by manipulating the workpiece at a minimum of four axes. A prototype rig motivated by four stepper motors and controlled by a micro-computer …

Microstructure and mechanical properties of cold drawn steel wires
Cold drawn eutectoid steel wires have been widely used for a variety of applications, such as suspension bridges, steel cords for automobile tires, and springs. Much research has been done to increase their mechanical strength. With advances in modern production technology, both the drawing speed …

Hydrodynamic lubrication and coating of wire using a polymer melt during drawing process.
… a polymer melt as the lubricant during the wire drawing process. The device is heated to convert the polymer feed into a viscous melt and the pressure required is generated by a hydrodynamic action produced by the motion of the wire. On the basis of experimental evidence, it is apparent that …
