Lawd – Laser Assisted Wire Drawing
In conventional wire drawing the diameter of a wire or rod-like workpiece is reduced by drawing it through a conical die. Dieless drawing of a wire or a rod is realized by a localized heating of the work piece. As heat source for example an induction coil can be used. Immediately after having passed the heating zone the work piece is cooled to restrict the heat input on very small region. By ap...
متن کاملEffect of Wire Pitch on Capacity of Single Staggered Wire and Tube Heat Exchanger Using Computational Fluid Dynamic Simulation
Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...
متن کاملAdvances in wire drawing process by theoretical and numerical analysis
Ductile metal deformation processes aimed at production of wire of some sort are in use since over five thousand years, early ones dating back to the origins of copper and gold produc tion. Thin sheets, initially produced by hammering, were cut into thin strips suitable for ornamental pur poses. The introduction of die plate paved the way to round wire manufac turing, rather severe limitatio...
متن کاملNiobium-Titanium Superconducting Wires: Nanostructures by Extrusion and Wire Drawing
Nano-fabrication is not new to the manufacturers of superconducting wires, in fact the dominant commercial superconductor, Nb-Ti, relies on a mechanically induced nano-structure for its remarkable properties. In this paper we show how these wires are manufactured so that their microstructure achieves the same scale as the superconducting vortex spacing. Recent attention on superconductors has e...
متن کاملThe Challenge: Improving the Efficiency of a Tube Drawing Bench
Greenville Tube Company (GT), a manufacturer of high-precision, small-diameter stainless steel tubing, conducted an in-house system performance optimization project to improve the efficiency of its No. 6 tube drawing bench. This tube drawing bench plays an integral role in the production process, but severely hindered the productivity and energy efficiency of the facility. GT’s plant engineer, ...
