wire drawing, The making of wire, usually from rod or rod. The wire drawing process consists of directing the rod, threading the end through the die and connecting the end to the draw block. The block, which is driven by an electric motor, pulls the lubricated rod through the die, reducing its diameter and increasing its length. A good thread is produced on a multi-block machine because the reduction is not possible in one design. Wire nail making machine

Wires

Wires, wire, or thin rod, usually very flexible and round in cross-section, made of various metals and alloys, including iron, steel, copper, bronze, copper, aluminum, zinc, gold, silver, and platinum. The processes used basically all the same.

These threads are very short and several pieces must soldered or hammered end to end to make a large length.

Wires was guided

– For many centuries the wire was guided by hand with metal stones for a short length. The section to be drawn is hammered at one point by pushing into the die hole. The wire driver holds it with his hands or a compass and pulls it through the matrix, the size of the reduction is limited by the strength of the wire. Various methods are used to increase his strength, such as sitting on a hammock so that by strengthening his legs against the structure holding the cubes, he can pull his arms and push his legs.

Larger wire

Larger wire should make by hammering or rolling or both. In the 19th century, the requirements for large tons and long lengths of iron and copper wire became acute, especially after the invention of wire rope, the development of the telegraph in the 1840s, and the development of the invented telephone and barbed wire later in the 19th century.e ie. Bessemer and open gray steel manufacturing processes and new bar rolling machines and methods meet these requirements.

The wires now taken from a piece of hot-rolled steel called a rod. (Rods made of some softer metals can shape by extrusion or pressing instead of rolling. The rods cleaned of scale (oxides formed on the surface) by immersion in dilute sulfuric acid. Depending on the material. Acids other than a molten salt bath such as sodium hydride can use. As can mechanical scale removers. Metal sandblasting is sometimes used to clean the spring wire.

metal

After cleaning the acid, the metal  washed. And immersed in a coating solution such as lime emulsion, borax. Or phosphate to neutralize any remaining acid. And act as a lubricant in subsequent wires drawing operations. The wires drawing process consists of directing the rod, threading the end through the die. And connecting the end to the drawing block as shown in the figure. The block, which drives by an electric motor. Pulls the lubricated rod through the die. Reducing its diameter. And increasing its length. For smaller wires sizes, reduction in one design is not possible and a multi-block machine consisting of a number of single-block machines built into one unit used.
