钢丝矫直机

Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine changes the straightness by squeezing the bar or the like through the straightening roller. Generally, there are two rows of straightening rollers, and the number varies. There are also two-roll straighteners, which rely on the angle change of the two rolls (concave in the middle, hyperbolic rolls) to straighten materials of different diameters. The main types are pressure straightening machine, balance roll straightening machine, shoe roll straightening machine, rotary reverse bending straightening machine and so on.

The position of the roller is at a certain angle with the direction of movement of the straightened product. Two or three large ones are active pressure rollers, which are driven by the motor to rotate in the same direction. Several small rollers on the other side are driven pressure rollers. It is rotated by the friction of the rotating rod or pipe. In order to achieve the required compression of the product by the rollers, these small rollers can be adjusted forward or backward at the same time or separately. Generally, the more the number of rollers, the higher the precision of the product after straightening. After the product is bitten by the roller, it continuously moves linearly or rotationally, so that the product is subjected to various deformations such as compression, bending, and flattening, and finally achieves the purpose of straightening.
