MORE INFORMATION

As with the QUADRO profiling machine system, the QUADRO-KS variant can also produce sheet metal profiles from a wide range of applications in a user-friendly manner and within the shortest possible changeover time in the highest quality with just one basic machine. The well-known exchangeable cassette system with 10 or 12 forming stations is used to produce the various profile shapes.

Due to the clever design, the customer is able to determine the equipment and thus the application area of the machine individually himself. Of course, the machine can also be retrofitted at any time with additional cassettes or extensive accessories.

The QUADRO-KS is built on a robust base frame and is designed to be mobile with 4 castors. Two casters can be fixed to prevent unintentional rolling away. Furthermore, the crane lugs included in the scope of delivery and the forklift pockets attached to the frame enable the machine to be transported safely on the construction site. This ensures flexible use of the machine both in operation and on the construction site. Hinged covers, which are secured by a safety device, protect the machine and the operator and facilitate the adjustment work.

The infeed width can be continuously adjusted between 300 and 800 mm via a handwheel with the proven spindle system. For tapered operation, the spindle adjustment is disengaged so that the adjustment side can move freely laterally in a special linear guide, depending on the inclined position. In the infeed area, the QUADRO-KS is equipped with robust ball-bearing infeed guides on the right and left for stable guidance of the strip material. These are designed to be separately adjustable for adjusting the outer edges of the profile. This allows the strip to be fed smoothly and without play.

The additionally reinforced cut-to-length roller shear located in the infeed area consists of a cutting head with hardened roller blades which can be reground or replaced as required with little effort. The cutting head is mounted on a maintenance-free linear roller guide and is driven by a toothed belt. This ensures a clean and burr-free cut. The shortest share length for this cutting method is approx. 700 mm. For shorter coulter lengths from approx. 100 mm, additional cutting devices are optionally available for mounting in the outfeed area of the QUADRO. Depending on the material and profile type, a QA60 (only for non-ferrous metals) can be used for the cut-off. For the production of conical profile webs, the QUADRO-KS is additionally equipped with an LS longitudinal cut-off device in the infeed area. This allows the conical longitudinal cut to be made before profiling.

In the subsequent profiling area, there is the proven interchangeable cassette system. Depending on the profile type, cassettes with 10 or 12 profiling stations can be accommodated there. The profile can be changed in a very short time by swiveling the cassettes or by changing the cassettes. When swiveling the cassettes, the changeover time takes only a few minutes and it can be implemented quickly and easily without auxiliary equipment.

Auxiliary equipment such as a forklift, table crane or overhead crane is required for cassette changeover. But here, too, the maximum changeover time is less than 20 minutes. The hardened and surface-treated profile rollers of the exchangeable cassettes are preset at the factory for material thicknesses between 0.5 – 0.7 mm (exception: special or facade profiles optionally 0.6 – 0.8 mm or 0.8 – 1.0 mm). For automatic processing of different lengths and quantities, the QUADRO-KS is equipped with a PLC. Input is made via a menu-guided touch panel. For the conical profiling operating mode, a separate submenu is called up on the touch screen. There, the necessary length entries for short width A, long width B and web length can be entered directly via a touch screen on the control. The control system then calculates a setting value for the inclined position of the cassette on the adjustment side. For this purpose, the cassette is adjusted by means of a handwheel via an adjustment spindle according to the specified value and then manually pushed to the start position. In the conical profiling mode, profiling can only be performed in a single cycle. This means that after the profile has left the machine, the movable cassette of the adjustment side must first be pushed back manually to the start position. Then the next web is conically cut and profiled.

When profiling from coil in the parallel profiling operating mode, the desired length and number of pieces are first entered on the touch panel. The manually fed strip material is drawn into the machine by means of the driven transport rollers. Once the programmed length has been reached, the drive, which is controlled by a frequency converter, stops and the cut-off cut is made automatically by means of driven roller shears. The overrun and thus the length tolerance is approx. 1 – 2 mm. In automatic mode, the restart of the next web is automatic. In single-cycle mode, the restart is triggered by the operator in each case. After the last profile web has been separated, further material feed can be stopped via a coupling lever and the belt can be retracted manually from the feed area.
