Function of Straightening Machine in Aluminum Circle Production

Aluminum disc circle is an important raw material in industrial production of cookware, lighting parts, traffic panels etc. When you spot pieces of aluminum round sheet, has it ever occurred to you that these round flat pieces were made from coil rolls of a certain strength? How did the rolls become so flat? The secret lies in the adoption of a straightening machine which functions to flatten the rolls into even sheets that are further cut into aluminum disc circle pieces of given sizes.

The straightening machine is a device for straightening metal profiles, bars, pipes, wires, and the like. All aluminum circle manufacturers must have such machines in their workshop, because most of the time they receive raw materials in rolling forms. The raw materials are made into rolls rather than sheet for convenience of delivery, since rolls take up less space and are less likely get damaged during delivery. The straightening machine presses the roll, the sheet, and the like by the straightening roller to change the straightness. There are generally two rows of straightening rolls, varying in number. There are also two-roll straighteners that rely on angular changes in two rolls (intermediate concave, hyperbolic rolls) to straighten materials of different diameters. The main types are pressure straighteners, balance roller straighteners, shoe roll straighteners, rotary contra-curving straighteners etc.

During the working process of the straightening machine, the position of the roller is at an angle to the direction of movement of the straightened product. Two or three large active rolleres are rotated in the same direction by the motor belt, and several small rollers on the other side are driven. Pressure rollers that are rotated by the rotating rod or tube friction. In order to achieve the required compression of the rolls to an aluminum roll, 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 finished product after straightening. After the aluminium roll is bitten by the roller, it is continuously linearly or rotationally moved, so that the roll is subjected to various compression, bending, crushing and the like, and finally the straightening is achieved.
