Topic: Wire drawing


  
  Wire - Wikipedia, the free encyclopedia
Wire is usually drawn of cylindrical form; but it may be made of any desired section by varying the outline of the holes in the draw-plate through which it is passed in the process of manufacture.
Wire has to be pointed or made smaller in diameter at the end before it can be passed through the die; the pointing is done by hammering, filing, rolling or swaging in dies, which effect a reduction in diameter.
Wires and cables for electrical purposes are covered with various insulating materials, such as cotton, rubber, or plastic, wrapped in concentric fashion and further protected with, substances such as paraffin, some kind of preservative compound, bitumen or lead sheathing or steel taping.

 Making Wire
Drawing is performed on the draw bench, which comprises the draw plate and a power reel for pulling the wire through.
In wet drawing, the wire is given a lees coating by passing it through lees liquor composed of water and some kind of flour, sometimes fermented and sometimes mixed with milk of lime.
In galvanizing, the wire is passed (a) through a lead bath to anneal it; (b) through a weak pickling solution to remove the scale formed; (c) through a rinsing bath; and (d) through the molten spelter contained in the galvanizing pan.

 [Ganoksin] Jewelry Making - Wire Drawing Hints
The trick to drawing wire by hand is to grasp the tapered end that sticks out the front of the drawplate with the pliers in such a way that there are some 5 mm of play; of movement back and forth to the drawplate.
For example a square or round wire is flattened, folded over, soldered to close the 'loop' and drawn through a square hole in the drawplate to produce two triangular wires.
A draw bench is extremely useful and one may be constructed from wood and canvas or with a boat winch and board.

Drawing takes place in drawing machines, in which the motor power is transmitted from the block motor(s) to the wire via the block(s).
The drawing dies and the blocks for dry drawing are therefore cooled with water to reduce the temperature.
Wire to be further drawn is prepared with a lubricant carrier, mainly depending on type of drawing method.

 Fine Wire Drawing Machines - Jaikvin Enterprises, India
This pointed wire is inserted through the die of the first Wire Drawing Machine and fastened to a locking device on the drum.
The starting end of the drawn wire is released from the lock of the first drum, is passed through the overhead loop and pulley provided, is brought down and is inserted through the die of the second drum and drawn through this die for further reduction.
Thus, the wire is drawn through all the wire drawing drums of the set in a continuous manner to get the required finished diameter of the wire.

 wire drawing --  Britannica Concise Encyclopedia Online Article
Fine wire is made by a multiple-block machine, because the reduction cannot be performed in a single draft.
The cold drawing of wire is an important and special sector of steelmaking.
Their sound is produced when a slender length of material—usually wire, plastic, silk, or animal gut—is made to vibrate by being stroked with a bow, plucked with a finger or plectrum (pick), or struck with a harder object.

 Wire Drawing
The art or process of wire drawing like the name implies is to draw a wire of a bigger diameter through a hole with smaller diameter hereby reducing the diameter through plastic deformation while the volume remains the same.
The wire ends are secured by two clamps one end to each clamp and the wire ends are then moved together at the same time as electricity is passed between the two clamps through the wire.
The drawing blocks are made of forged C 50 carbon steel, induction tempered at medium frequency, to obtain a surface hardness of approximately 60 HRC.

It allows to draw wires from 15 mm down to 0.5 mm in successive passes.
The drawing dies are made of tungsten-carbide (with cobalt-binder).
Before each pass the wire is pointed with a swaging machine; it is then inserted through the conical die and clamped to the drawhead.

 Wire Drawing   (Site not responding. Last check: 2007-11-04)
Wire drawing is a metal-reducing process in which a wire rod is pulled or drawn through a single die or a series of continuous dies, thereby reducing its diameter.
Because the volume of the wire remains the same, the length of the wire changes according to its new diameter.
Increases the length of the wire as its diameter decreases

One set of hardware provided rigid alignment of the wires to their wire drawing die axes within 0.35 degrees using ''hydrostatic pressure stiffening'' to enable the precision guidance strategy to be implemented for these highly flexible small diameter wires.
Research findings and results: In Phase 1, a breakthrough in wire drawing technology for A-15 superconductor composites was achieved by dramatically limiting or eliminating breakage in four different A-15 composite precursor wire designs during the drawing of these very desirable composites that previously could not be drawn to near final size.
A portable Advanced Wire Drawing Station will be developed and constructed in the final stage of the proposed Phase 2 program and it will be used in an outside manufacturing facility for superconductor composite wire drawing field trials.

 What is wire drawing?   (Site not responding. Last check: 2007-11-04)
Wire drawing is an operation to produce wire of various sizes within certain specific tolerances.
The process involves reducing the diameter of rods or wires by passing them through a series of wire drawing dies with each successive die having smaller bore diameter than the one preceding it.
The final wire size is reached as the wire passes through the last die in the series.
