The necessity of wire rod straightening machine and its working principle
- Oct 30, 2018 -

With the improvement of industrial development level, the demand for wire rods has risen sharply, and the requirements for wire rods have become higher and higher. Because the wire processing is simple, the weight is light, and it can withstand large loads, it is widely used in engineering. Due to different requirements of wires in different departments, it includes a wide range of products, large specification range, high shape precision and good forming performance. The surface requirements are strict, resulting in a variety of wire specifications and model requirements. At the same time, higher and stricter requirements are imposed on the processing quality of the wire.

 

Straightening the wire by the wire rod straightening machine is to subject the wire to a certain mode and a certain amount of external force, resulting in a certain elastoplastic deformation; when the external force is removed, the elastic force is restored under the action of the internal force until the internal force reaches A new balance to achieve the required leveling effect; the straightening process - essentially the elastoplastic deformation process.

 

In the straightening process, usually the roller position of the wire straightening machine is at an angle to the direction of movement of the straightened product, and two or three large are active pressure rollers, which are rotated by the motor belt in the same direction, and the other side is rotated. The small rolls are driven pressure rolls that are straightened by the friction of the round bar or tube. In order to achieve the required compression of the rolls to the article, the small rolls can be adjusted either forward or backward, either simultaneously or separately. Generally, the greater the number of rolls, the higher the accuracy of the product after straightening. After the product is bitten by the roller, it continuously moves in a straight line, so that the product is subjected to various compression, bending, crushing and the like, and finally achieves the purpose of straightening.
