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 کاملInfluence of an Inclusion on Multi-Pass Copper Shaped-Wire Drawing by 2D Finite Element Analysis
The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...
متن کاملUse of sutures as Kirschner wire and tension-band wire for olecranon fractures: a technical note.
Open reduction and internal fixation using tension-band wires for displaced olecranon fractures enables restoration of extensor function. We report on 3 elderly patients with a displaced olecranon fracture who underwent open reduction and internal fixation using sutures as the Kirschner wire and tension-band wire and achieved good outcome.
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...
