Numerically Controlled Three roll Planetary Bending Machine

Numerically Controlled hydraulic Three Roll Planetary Axis Machine (Model No. 3R----PANCH)

The pre bending / edge bending and rolling can be performed in the same machine.

❮ ❯

Advantages

The machine can be operated remotely from all around
Since all roll movement and roll rotation are completely numerically controlled, skilled manpower is not required
Specially developed hydraulic circuit to achieve side roll positional accuracy within ±0.2 mm
Since all rolls are mounted in roller bearings, the electrical consumption is reduced by 50% compared to conventional pyramid type machines

Special Features

The machine frame is fabricated from all tested steel plate material. A Die Penetration test is carried out on all weld joints to ensure sound weld quality. This frame is subjected to stress relieving, sand blasting and epoxy primer . painted for corrosion free long lasting machine life.( Primer paint 160 DFT). The complete body frame is machined in CNC machine to achieve built.

A adjustable control desk with wheels is provided. The main panel start / stop buttons and roll rotation function (Reverse / forward) is provided on the same. Both the side roll left side position and right side position are indicated separately by total four digital meters.

A specially designed & built mechanism allows drop end frame to tilt down in horizontal position without much efforts The top roll can be tilted to great degree of inclination making it most convenient and ease to remove rolled shells without any difficulty .

All machine four rolls are mounted in heavy duty roller bearings. Each roller is fitted with two bearing per side(four bearing per roller).

A dual cone bending device can be provided as shown. The attachment provided between bottom rolls is sutable for narrow cone diameter with lower thickness. The attachment to be fitted on a main frame is suitable for cone having wide angle.

An extended rolls can be provided mounting dies to roll different section likes angle, chaneel , pipe, beam and flats etc.

The top roll can be tilted to great degree of inclination for ease of rolled shell removal.
