Automation specialist Advanced Sheetmetal Technologies has released to the Australia and New Zealand markets, a series of rounding machines from German manufacturer Prinzing.
RM 20 – RM 100 three roll bending machine:
These have an asymmetrical roller arrangement (roller tensile strength 700 N/mm2) with an upper roller that can be swung out forwards by quick release.
A right upper roller lock bearing is provided with a hardened running bush, and all gear wheels are arranged on the left, and therefore provide easy removal of the tubes.
Conical wrapping of sheets is achieved by inclination of the rear roller, while the machine achieves rapid setting of a lower roller.
Worm adjustment of the rear roller is possible with a mechanical digital display. A usable length of 1030 mm rollers can be turned spherically.
Special accessories include a gear wheel put in (RM 42 inclusive), underframe (RM 60 inclusive), fold slots, wire inlay grooves, hardened rollers and side stop for conical wrapping.
RME 20 - RME 120 roll bending machine:
The design features are as for the RM 20 -RM 100, but with special accessories for this roll bending machine.
There is a pole changing motor for two speeds, three roller drive, folding groove in the upper roller, wire inlay grooves, hardened rollers, hardened and tempered rollers, ground rollers, rubberised rollers and a side stop for conical wrapping.
The pneumatic bending device has four rollers; there is a support table and program sequence, and a motorised feed of the lower roller.
Standard accessories include a single stage transmission brake motor, double foot switch for forward and reverse running, switching cubicle with safety control, conical wrapping device and underframe.
RAE 42 – RAE 100 four roller automatic rounding machine:
This unit is driven by an infinitely variable controlled brake motor and has a pneumatically operated flap bearing, pneumatically operated lower roller in feed, high strength bending roller and supporting with stop for sheets up to 500 mm wide (tube 160 mm diameter).
A control table has NC control and is operated by touchscreen for setting up and automatic operation. Programme memory has 99 programmes; there are 30 bending steps per program, an alphanumeric program input, programmable fast and creep speed, and a step display for setting up an automatic operation.
All programs are write protected, while the program is programmable from an external PC.
RAE automatic rounding machine with robot:
This unit integrates a robot blank loader and roll formed tube unloading. It has an articulate robot arm to provide proven material handling reliability and integrated programming for all RAE tube roll performing models.
It has quick and flexible part handling features set-up used for effective blank and roll formed tube handling.
When roll formed tube is unloaded, it is placed in a buffer area. Articulated blank and tube handling solutions are provided for tube diameters ranging from 60mm to 500mm, and maximum part weight of 30 kg.
