Profiling machine QUADRO

The QUADRO profiling machine is a versatile and multi-functional profiling shaping system. The basic machine is designed to produce sheet metal profiles for a large variety of applications with a user-friendly system and very short retooling times.

The profiling machines exchangeable cassette system with 10 or 12 forming stations provide for very short retooling times for different profiles. This means that the Quadro machine can be used effectively and economically for a variety of different profile shapes.

An ingenious design permits customers to select the required equipment individually, i.e. the type of application of the machine. The machine can also be upgraded at any time by the addition of another cassette, or various accessories.

The QUADRO machine is supported by a robust base frame that is equipped with four wheels. Two of the wheels are equipped with brakes to stop the machine from moving unintentionally. The scope of delivery also includes lifting eyes as well as forklift pockets that are installed on the frame for the safe transportation of the machine on site. This ensures that the machine provides utmost flexibility, both operationally and on the construction site. Hinged covers secured by safety devices protect the machine and the operator and facilitate adjustments.

The infeed width is continuously adjustable from 300 mm to 800 mm with the well proven system employing a spindle and a hand wheel. The right and left side of the QUADRO machines infeed area are equipped with robust infeed guides on ball-bearings that feed the strip material safely and securely. These are separately adjustable to adapt to the outer edges of each profile. As a result, the strip will run smoothly and without backlash.

The cross-cutting disc shear in the infeed area consists of a cutting head with hardened roller blades that may be sharpened or even replaced with little effort if necessary. The cutting head is mounted on a maintenance-free linear guide and it is driven by a toothed belt. This guarantees a clean, burr-free cut. The shortest panel that can be produces with this separation process is about 700 mm. Additional dividing devices are available for installation in the outlet area of ​​the QUADRO machine where shorter panels from approximately 100 mm must be produced. Depending on the material and the type of profile, cutting may be performed by a QA60 (only for non-ferrous metals) or a hydraulic segmented separating shear (for double standing seam 25).

The exchangeable cassette system is arranged in the profiling area. Depending on the type of profile it may accommodate cassettes with 10 or 12 profiling stations. Retooling for different profiles is accomplished in no time by rotating or replacing the cassette. When rotating the cassette, the changeover only requires a few minutes and does not involve the use of additional equipment. The replacement of the cassette requires tools such as a forklift, a table-mounted crane or an overhead crane. Even in this case, the maximum time required is less than 20 minutes. The hardened and surface treated profile rollers of the cassettes are pre-set to material gauges of between 0.5 - 0.7 mm in the factory (except for special or facade profiles they may be set to either 0.6 - 0.8 mm or 0.8 - 1.0 mm). As with all Schlebach profile shaping machines, narrow panels, oblique panels and conical panels may easily be produced in just 2 operations and without additional tools.

The machine is equipped with a PLC to automatically process material in various lengths and quantities. Control inputs are entered via a menu-driven touch panel that is located in the infeed area of ​​the machine or that may be arranged on a rail between the infeed and outlet areas where it can be moved. The program with the profile shaping runs may be executed automatically or in single cycle mode.

Profiling from a coil requires that the desired length and the item count are entered first via the touch panel. In the machine, manually fed strip material is transported by driven transport rollers. When the programmed length is reached, the frequency converter controlled drive is stopped and the crosscut shear executes an automatic cut. The overshoot, i.e. the tolerance in length is about 1 - 2 mm. In automatic mode, the next strip is started automatically. In single cycle mode, the operator is responsible for the restart. When the last profile has been cut from the strip, the material feed may be stopped by means of the clutch lever before the strip is removed manually from the infeed area.
