The processing technology of the titanium wire

Hot wire drawing head machine is used first titanium rod head is small, with a tension will be relatively coarse titanium rod diameter from the aperture is smaller than titanium rod
A conical holes of around 1 mm drawing out, through drawing can make the original titanium rod diameter smaller, by drawing many times, can achieve very small diameter titanium wire.Simple said is the titanium rod after heating control above the recrystallization temperature of drawing processing of titanium wire is called hot drawing titanium wire.At room temperature using the drawing process of titanium wire titaniumcn is called cold drawing titanium wire.Cold drawn for pure titanium in general.
Features: hot drawing titanium wire has good plasticity, easy forming, after forming titanium no stress, to facilitate the following process.Cold drawing has the character of cold hardening titanium wire.

Under the action of drawing force, the wire rod or wire billets from wire drawing die die out, in order to produce small section steel wire or metal plasticity processing non-ferrous metal wire. In less than 0.05 mm diameter wire drawing, superfine wire wear die hard, in order to improve the stability of the drawing process, reducing frequency of tensile and wear mode, improve the efficiency of drawing production, can use safety coefficient K value is greater than 2.0.Cold drawing is the most widely used in the production of metal wire, wire drawing method.Hot drawing, metal wire into the die should be heated before, it is mainly used for high melting point metal such as tungsten, molybdenum and other metal wire drawing.Also need WenBa, wire through heating heater to the temperature of the specified range into the drawing die, it is mainly used for zinc wire, difficult deformation of wire, such as high speed steel, bearing steel wire drawing.According to metal wire drawing process through the mold number of points at the same time, only through a mold drawing are drawing, single channel time sequenced by several (2 ~ 25) mold drawing is multichannel continuous drawing.Single channel of drawing line speed is low, productivity and labor productivity is low, often used in the wire diameter, low plasticity and special-shaped wire, wire drawing.Multi-channel time drawing wire speed is high, high mechanization degree of automation, high productivity and labor productivity, is the main way of wire, wire production.It points the sliding type continuous drawing and sliding type continuous drawing.According to used when drawing lubricant state points, using the liquid lubricant is wet drawing, use of solid lubricant is dry drawing.According to the drawing of wire section shape, circular wire drawing and special-shaped wire drawing.According to the role of by drawing on the wire tension, there are tensile drawing and drawing.There are special drawing, such as roller die drawing, etc.
Process characteristics of wire drawing stress state for two to three to the main tensile stress in the compressive stress is always stress state, with three compared to principal stress is compressive stress state, achieve more easily by drawing wire plastic deformation condition.Drawing deformation condition for two to compression deformation always tensile deformation of three to the main deformation state, the state of play of plastic, metal materials are easier to produce and the exposed surface defects.Metal wire drawing process in the way of deformation restricted by the factor of safety, including a small deformation are drawing way once more, so in the production of metal wire in multichannel continuous high-speed drawing.
