Description
There is a trend of producing and processing high-strength process materials with large diameters between 5 mm and 40 mm. The AS PO roll straighteners offer very high straightening forces and have been developed for high strength process materials with a diameter or cross-sectional height of between 5.0 mm and 40.0 mm in two different sizes and are built in the German tradition of high quality and innovation.
The straightening of such materials requires straighteners which have more than 5 straightening rollers per plane and combine features such as high-speed closing and opening with the adjustability of all rollers. While a higher number of rollers are recommended because of the high material strength, the other features are indispensable for good handling of the process material and for ensuring an identical zero line for different diameters. Using the newly developed straightening modules of the AS PO series it is possible to build straighteners which meet all the previously mentioned requirements because the modules themselves are already designed and configured to this end.
The straightening module AS PO, which holds an adjustable straightening roller and can be used in conjunction with the non-adjustable AS FX module. Roller adjustment of the AS PO is performed using a hydraulic cylinder whose piston moves the built-in roller component against a stop which can be adjusted to a defined position. The defined adjustment of the stop is provided by a mechanical position display and is performed manually with little force using a suitable tool.
Alternatively, it is possible for the stop to be adjusted by means of an electromotive drive using related hardware and software. Mounting several AS PO straightening modules on a sub-plate creates a straightener with high-speed opening and closing capability and rollers which can be individually adjusted to defined positions.
Variable configuration of the roller pitch is also possible, thus enabling the straightening process to be adapted to both the diameter and the strength of the process material. Through this expansion of the straightening range it is possible for example to process not only wire but also tube with great cost effectiveness in large as well as small batch sizes.
