wire drawing machine is various, according to the size of wire drawing can be divided into: micro pull machine (wire diameter unit: wire),
small pull machine (wire diameter unit: 0.xmm), medium tension machine (wire diameter: mm),
wire drawing machine (wire diameter: 1x mm) from the internal control mode and mechanical structure of wire drawing machine,
can also be divided into tank type, pulley type, straight into the main types of. for different requirements,
different precision rules of the product, different metal materials, can choose different specifications of wire drawing machine.
but in the steel wire production enterprise and the high end silk material, according to the material characteristic, its precision request and the drawing stability are high,
therefore, the use of straight wire drawing machine. although the drawing process is different,
however, the working process can be divided into 3 parts: wire drawing, wire drawing, wire drawing and so on.
for the wire drawing machine, the control of the wire is not too high,
most of the wire drawing machine, the operation of the line is driven by frequency converter to achieve the,
but there are also a number of double frequency control of wire drawing machine, or even directly through the wire drawing tension wire drawing into the wire drawing machine,
free line. wire drawing is the most important part of wire drawing machine. different metal materials,
different kinds of silk and requirements, drawing link is very different, this paper will be analyzed in detail the design of straight wire drawing machine automatic control system.
the working speed of the receiving link determines the efficiency of the whole drawing machine, and is also the most difficult part of the whole system.
in the receiving part, the common control technology is the synchronous control and tension control.
special engineering plastics, also known as high performance engineering plastics, in the long-term use temperature of 150 degrees celsius,
can still maintain good mechanical properties, electrical properties, dimensional stability. special engineering plastics are mostly flame retardant materials,
mainly used in national defense, aerospace and cutting-edge technology and other related industries. the performance of special engineering plastics is more excellent and unique,
however, most of the large-scale industrial production or production scale is not large, the use of relatively narrow, such as fluorine resin (fr),
thermoplastic polyurethane (tpu), polysulfone (psu), polyether ether ketone (peek), etc..
