This paper studied the pulse generator and conductive device between metal wire and electrode for electroplastic wire drawing. We adopted the powerful GTR module on the design of the pulse generator, which makes a great superiority in the pulse waveform. The experimental results show that the design project is feasible and effective. In this paper, we displayed three types of conductive device between metal wire and electrode. According to the results of the experiments, the advantages and disadvantages of the three types of conductive device were discussed. Moreover, we also discussed the sel

Abstract:

The drawing of wires with round cross section is a widely used technological method for making a great number of wire products of different range of sizes having excellent material- and surface quality. The planning of any kinds of wire drawing technology is greatly facilitated by knowing the models describing the technological parameters in the best possible way. Mainly the finite element method (FEM) and the analytical method are used for modelling the above parameters. Contrary to FEM, the advantage of the continuous analytical models is that they require less calculation processes and this

Abstract:

Torsion bars are used in automotive engineering as well as in other industrial applications. Such elements are produced by bending cold drawn wires. In conventional drawing processes tensile residual stresses occur near the surface of the wire. Small bending radii, which are required in limited assembly spaces, result in component failure due to reduced formability. Additional operations such as heat treatment or shot peening are necessary to influence the residual stress of the wire and to improve the dynamic stability of the torsion bar. The aim of the research is to reduce tensile residual

Abstract:

The most important activity of wire drawing technology is the correct design of stages geometry. The wire drawing within a roller die is described by an irregular deformation on wire width, strongly connected by the gauge shape between the rollers and cross section wire surface. Free lateral wire surface that has no contact with the roller on the deformation zone obstructs the wire elongation. There is a biunique correspondence between the shape and dimension of wire that enters between the rollers, and the free space between the rollers, corresponding to a specific stage of drawing.

Ultrasonic drawing is a new technology to reduce the cross-section of a metallic tube, wire or rod by pulling through vibrating dies. The addition of ultrasound is beneficial for reducing the drawing force and enhancing the surface finish of the drawn wire, but the underlying mechanism has not been fully understood. In this paper, an axisymmetric finite element model of the single-pass ultrasonic drawing was established in commercial FEM software based on actual wire length.

A semi-dieless drawing technology has the advantages of producing a large deformation in a single pass and achieving high-precision dimensions of the finished products. However, instabilities can easily occur in a technique with a large amount of deformation, resulting in its failure.

The instability mechanism of the semi-dieless drawing is proposed and validated by experiments.

This article outlines the history of wire drawing technology. The origin of wire drawing tools has been traced to well before 2000 BC era. The earliest examples are found in Egypt where gold wire was drawn to make jewelry. Anywhere in the spectrum between making jewelry and building bridges, the work starts with an elongated metal billet, which has been shaped by hand working or machine rolling. One end is reduced to a diameter that will pass through a funnel-shaped die, which is typically circular although it is possible to extrude other cross-sections.

Abstract:

Drawing deformation behaviors of AISI 1070 steel in conventional lubrication and electrochemical environments were compared. The anodic polarization in the electrochemical drawing not only decreases much the deformation resistance but also eliminates the work hardening. This can only be attributed to the reaction on the surface of the wire before it passes through the die. This chemomechanical effect, which is governed by surface dissolution rate, facilitates dislocation slip and permits a much smooth high speed drawing. It was a promising technology for the forming of brittle hard metal mater

Abstract:

The forces during wire and tube drawing can be reduced by ultrasonically oscillating dies. It is a major problem of conventional wire and tube drawing to introduce high forces into the forming area. Compared to conventional wire and tube drawing, the forming process limits can be extended by superimposing ultrasonic waves due to decreasing drawing forces. Different techniques can be used to excite the die. One possibility is the variation of the vibration mode. In tube and wire drawing, the dies are usually excited longitudinally.

Abstract:

The paper focuses on 6xxx series AlMgSi conductor alloys. Such alloys are used for manufacturing of conductors for power transmission. Since the most current standards define as many as seven types of wires with various mechanical and electrical specifications, the existing philosophy of AlMgSi wires manufacturing technology for electrical applications has to be revised. Strength specifications of precipitation hardened AlMgSi alloys may be enhanced by strain and by precipitation hardening. Therefore from the scientific point of view identification seems to be relevant of the impact of the seq

The article presents a method for determining the residual strain in the steel wire cord of construction 3x0,30. The causes of residual strain, the effect on the quality of finished product and the determination of the degree of residual strain by chemical method are considered. The cause of residual strain is uneven plastic deformation of a solid body due to various changes in different places of its length and volume. Residual strain of steel wire cord are made up of stresses existing in the wire after drawing, and the stresses created during the lay of wire.An important task in the framewor

Abstract:

It was recently reported that a UK company has developed a naturally non-toxic magnetoferritin to act as a draw solute for drawing water in forward osmosis process. The gist of this technology is the utilization of the magnetic nanoparticle and high-gradient magnetic separation for draw solute separation and reuse. However, any demonstration on this technology has not been reported yet. In this study, a feasibility test of magnetic separation using magnetic nanoparticle was therefore performed to investigate the possibility of magnetic separation in water treatment such as desalination.

Tungsten inert gas arc welding–based shaped metal deposition is a novel additive manufacturing technology which can be used for fabricating solid dense parts by melting a cold wire on a substrate in a layer-by-layer manner via continuous DC arc heat. The shaped metal deposition method would be an alternative way to traditional manufacturing methods, especially for complex featured and large-scale solid parts manufacturing, and it is particularly used for aerospace structural components, manufacturing, and repairing of die/molds and middle-sized dense parts.

Abstract:

The mathematical analysis of plastic flow processes under uniform plane, axisymmetric and volumetric deformation is carried out. The analysis is based on the external shape change of the body, which determines the movement of material points. It is shown that the plastic flow of an isotropic rigid-plastic body under plane deformation obeys the hyperbolic law, and for axisymmetric and volumetric deformations – the inverse square law. Spatial-geometric expressions of these laws made it possible to reveal and explain in a new way the physical essence of plastic shear. It is proved that the stress

Abstract:

Tungsten cemented carbide (WC-Co) is a widely applied material in micro-hole drilling, such as in suction nozzles, injection nozzles, and wire drawing dies, owing to its high wear resistance and hardness. Since the development of wire-electro-discharge grinding (WEDG) technology, the micro-electrical discharge machining (micro-EDM) has been excellent in the process of fabricating micro-holes in WC-Co material. Even though high-quality micro-holes can be drilled by micro-EDM, it is still limited in large-scale production, due to the electrode tool wear caused during the process. In addition, th
