VOORTMAN MO CLASSIC ROLLERBED

The MO-Classic Rollerbed covers our classical machines without the need for a chuck clamping system, primarily for round pipes with a maximum diameter of up to 1.500mm (60") and up to a pipe weight of 24 tons. Reduce dead zones, save material and increase margins.

VOORTMAN MO CLASSIC (PIPE, SQUARE & RECTANGULAR CUTTING)

The thermal profiling of square and rectangular pipes is possible in addition to cutting round pipes. To achieve the cut contours on square and rectangular pipes, the machine is extended by a transverse axis (7th CNC axis).

VOORTMAN MO CLASSIC (PIPE & DOME CUTTING)

The thermal cutting of dishes can easily be done on the machine. It saves you lots of handling time and brings high quality cuts in dished ends. To execute cutouts (holes) with weld bevel preparation on dished ends the machine will be equipped with a tiltable chuck which is hydraulically rotated from its standard position through 90° onto its back. This tilted chuck can then take and clamp dished ends with the same minimum and maximum diameters as round pipes while saving you extra working space.

SOPHISTICATED SOFTWARE FOR PIPE CUTTING MACHINES

COROBS® & COROBS PLUS®

Our software solutions for machines and processes make the production workflow for our customers more efficient. Our thermal cutting machines make 3D contours as part of an integrated process chain rather than an isolated element.

FEATURES & PROCESSES
FOR CUTTING

TORCH HEAD

The torch head makes it possible to adjust the machine torch by +/- 70°. This means that the torch can be adjusted within a range of 20° to 160° in relation to the pipe axis. The torch head can also rotate 360° about its own axis. The torch head is protected from dust, dirt and cutting particles.

LASER SENSOR

To correct variations between the cutting torch and pipe surface. Before cutting, the laser sensor scans the pipe. The measured points are then compared to the actual pipe diameter. The software interpolates a correction value for the height of the torch head. The distance between the torch and pipe surface is thus kept constant over the entire cutting curve.

ELECTROMECHANICAL TRACER

The vertical height adjustment axis is equipped as standard with a laser sensor. The electromechanical tracer measures the circularity errors on the pipe during the cutting operation.
This tracer is optionally used in addition to laser sensing: When heat-induced deformation becomes excessive particularly. The case of small-diameter pipes when a ball gutter is used, or when large pipes are processed. Tracing is also used when pipes have a glossy coating or a highly irregular surface texture.

SLIDE SYSTEM

The adjustment of the distance from the torch to the pipe surface can be automatically tracked in any angle position by means of the slide system. This system maintains the right distance in order to ensure the optimal cutting quality, even in fast plasma cutting processes.

OXY-FUEL CUTTING PACKAGE

The package comprises a solenoid-valve-controlled gas supply, manometer for setting gas pressure, ignition torch, solenoid-valve-controlled cutting torch, cutting nozzle package for different cutting thicknesses and an operator protection package. With this package, it is possible to cut pipes up to a maximum wall thickness of150 mm (5.9”) or a maximum length of cut of 200 mm (7.8”).


PREHEATING TORCH

The preheating torch employed yields to better cut contours. A preheating torch reduces cutting time with 50%, given a flame cutting angle of 45°.


PLASMA CUTTING

For cutting with plasma, we employ products from the American manufacturer Hypertherm, who rank among the leading companies in this line of business.


MODULE FOR CUTTING CONES

The thermal cutting of cones is possible. In addition to the original cutting of round pipes. For this, the chuck and pipe carriage have to be adapted.

FEATURES & PROCESSES
FOR MARKING & PRINTING

NEEDLE MARKING SYSTEM (AIRSCRIBER)

The needle marking system permits the drawing of axis lines in tank construction and the drawing of footprints in steel construction and tank construction. For the welding of previously profiled pipes it is also necessary that the two ends of a pipe meet the matching pipes from clearly defined angle positions. Marking is punched into the pipe surface. The needle marking system is situated in a separate printer housing at the cutting head and operates pneumatically.

NEEDLE PRINTING SYSTEM

The needle printing system permits the printing of texts on the pipe with different, pre-settable marking depths. The needle printing system is situated in a separate printer housing at the cutting head and operates pneumatically. This printing system has its own X-Y carriage and can therefore label very quickly without moving the machine.

LABEL PRINTING

A label printing system can also be provided. A printer positioned next to the chuck prints out the labels with information on the executed pipe cut. The label concerned can then be stuck by hand onto the cut pipe segment.

PLASMA MARKING SYSTEM

The plasma marking system of manufacturer Kjellberg is used for the marking, notching and punching of unalloyed and stainless steel pipes. The depth and width of the markings are preselected by means of the output current.

INKJET MARKING AND PRINTING SYSTEM

For complex applications inkjet printing can alternatively be used. The inkjet printer is accommodated in a separate printer housing fastened to the cutting head.

FEATURES & PROCESSES
FOR PIPE CARRIAGE

CARRIAGE FOR SQUARE AND RECTANGULAR PIPES

Square and rectangular pipes that have to be rotated in the chuck during the cutting operation require at least one support because of the increasingly large tipping moment.

MECHANICAL PIPE CARRIAGE WITH MANUAL SCISSOR-TYPE ADJUSTMENT

This very solidly designed pipe carriage supports the pipe with scissor-type carriers. It is designed for a load of 7,5 tonnes (16,500 lbs), depending on machine size. The pipe carriage is adapted to different pipe diameters with a manually operated spindle adjustment mechanism.

HYDRAULIC PIPE CARRIAGE WITH MANUAL SCISSOR-TYPE ADJUSTMENT

This pipe carriage supports the pipe with scissortype carriers. It is designed for a load of 2.5 or 7.5 tonnes (5,500 or 16,500 lbs), depending on machine size. The pipe carriage is adapted to different pipe diameters with a manually operated hydraulic adjustment mechanism.

CHUCK HEIGHT ADJUSTMENT

Chuck height adjustment becomes necessary if the pipe support solutions (fixed-height pipe carriage, manual or motorized ball gutter, motorized roller conveyor) are not height-adjustable. In this case, the machine software controls the automatic height positioning of the chuck centre based on the entered pipe diameter.

FIXED-HEIGHT PIPE CARRIAGE WITH MANUAL ADJUSTMENT OF ROLLERS

Fixed-height carriages for round pipes are employed together with a height-adjustable chuck. It is designed for a load of 3 tonnes (6.600 lbs), depending on machine size. The advantage of fixed-height over adjustable pipe carriages is that, for the many different pipe diameters, the time-consuming adjustment of the pipe carriage to pipe diameter is not necessary as the chuck is automatically adapted by its height adjustment mechanism to the pipe diameters on the pipe carriage.

MANUAL BALL GUTTER

As an alternative to the pipe carriages, the machine can be equipped with a ball gutter. Round pipes with a maximum weight of 2 tonnes (4,400 lbs) can be placed on the ball gutter. It is convenient if several pipe pieces are to be profiled out of a single pipe.

MOTORIZED BALL GUTTER

Equipped with a motor to ensure automated workpiece flow. These ball gutters are equipped with feed rollers positioned at intervals of 3,000 mm (10’). The minimum pipe length that can be carried is then 3,500 mm (11.5’).

HOLD-DOWN DEVICE

Pipes that are curved tend to flop over when rotated on the pipe carriages or on any of the other alternative support solutions. (This applies particularly to thin-walled pipes with small diameters). The pipe may then collide with the torch head and inaccurate cuts may arise. To rectify this problem, pipe carriages and the other alternative support solutions can be equipped with a pneumatic hold-down. This hold-down is designed for pipes with a maximum diameter of 160 mm (6.3”).

FLOATING CHUCK

Heavy pipes with large bends, non-circularity or pronounced welds cannot be easily centrically clamped without the pipe loosening itself in the chuck during the turning process owing to the forces applied. To take account of these forces, the clamp can be given a floating mounting. Forces are registered by an electronic measuring system. Large and heavy pipes with considerable deviations from the true can thus be securely and firmly clamped so that the pipe cannot slip during the cutting process.

STREAMLINE LOGISTICS, SIMPLIFY HANDLING

AND BOOST PRODUCTIVITY WITH AUTOMATION

Our automated logistics solutions come equipped with infeed racks, infeed conveyors, cutting conveyors, outfeed conveyors, and outfeed racks for streamlined performance. Advantages of our systems include easy pipe handling and up to a 30% increase in productivity.
