Levellers for sheet metal - Import export

If you need two Coil Reels to hold one coil, you need a Heavy-Duty Coil Feed Line above all. One that is designed extremely robust and knows to subdue even materials of highest bounce and largest cross-sections.To ensure this, we have taken no heed to cost savings but went by the maximum principle: 2 Coil Reels with high-performance arbors retain the coils from left and right. 2 x 2 hydraulic arms secure them from top and bottom – each with eight tons pressure force, each with hydraulically driven snubber roll. The loading is done with one central lifting gear built into a super-duty running frame for the V-nest. Hydraulic manipulators with pivoting and bending function support the threading of the material. On the receiving end, a Pre-Straightener with 200mm work rolls takes over, after hydraulic edge guides have ensured central entry. Now, if someone asks us our definition of “heavy-duty”: We find 36.000 kilogram coil weight and 2.

A perfect combination of space savings and dynamics: the GSW Compact Feed Lines Our Compact Feed Lines are an ideal answer to the challenge of a constraint floor and necessity to process thick materials. Marrying the processes of leveling and indexing into one Feeder-Straightener machine allows for a complete Feed Line with only two individual machines and thus greatly reduces the necessary length. Additionally, the decoupling of the coil mass from the indexing process – achieved through a short loop between Coil Reel and Feeder-Straightener – enables dynamic feeding despite the compact footprint. And, if cross-sections are especially big, the loop can be spared completely, creating yet more space. One more advantage, virtually a by-product out of their very nature, is the quicker set-up of our Compact Feed Lines. This elevates them to not only space- but also time-savers!

With Conventional Feed Lines, the focus lies on speed and material surface. That’s why Conventional Feed Lines are equipped with a Coil Reel for pull-off, a Straightener with variable frequency drive a coil loop and a Servo Roll Feed: the loop uncouples the more inert straightening process from the highly dynamic indexing process and thus allows for high line speeds and preservation of the material surface. Since productivity and capacity demands can vary significantly, we have created different control concepts: while small Feed Lines work with a simple pneumatic drag brake at the Coil Reel and an ultrasonic sensor to control the Straightener speed, the large Feed Lines get fully synchronized controls with motor-limited Coil Reels and a smart loop, creating a steady average speed of the whole line. This allows smooth pull-off of high coil weights while the loop remains very calm – in addition, the Servo Roll Feed can work with full dynamics, even at long indexing progressions.

Application areas for straightening presses include the sheet metal processing industry. Here, this type of press is used for the straightening of semi-nished products, such as the levelling of uneven sheet metal and slab surfaces, which are used in subsequent processes. In addition to high straightening accuracy, Siempelkamp straightening presses provide a broad straightening spectrum and high exibility in the further processing of sheet metal. For materials with a tensile strength of 1,300 N/mm2, sheet metal with a thickness of approx. 300 mm can be processed To do so, the presses are equipped with one or several straightening rams which can be operated together or individually. The pressing force needed for straightening is applied across the entire press width. Sheet metal can be straightened by cold or warm forming with sheet temperatures of up to 600°C.
