Elctro-Hdyrualic Operated Four Roll Planetary Bending Machine

Elctro-Hdyrualic Operated four Roll Planetary Axis (Model No. 4R---PAEH)

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

Advantages

The machine can be operated remotely from all around
Being a four-roll machine, the unbent flat is minimal and the smallest possible diameter is much tighter compared to a 3-roll machine
Specially developed hydraulic circuit requiring minimum maintenance
Since all rolls are mounted in roller bearings, the electrical consumption is reduced by 50% compared to conventional pyramid type machines
Since all roll movement and roll rotation are through hydraulic actuators, only one person is required to operate the machine with minimal effort

Special Features

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

A movable control desk is conveniently located on machine. The main panel start / stop buttons and roll rotation fucntion (Reverse / forward) is provided on the same. The Top roll left side position and right side position are indicated separately by four digital meters.

A specially designed & built mechanism allows drop end frame to tilt down in horizontal position without much efforts (one person can perform job). No need to dismantle frame from main body like in conventional machine. 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 our machine 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 suitable for narrow cone diameter. The attachment to be fitted on a main frame is suitable for cone having wide angle.

An extended rolls can be provided for mounting dies to roll different sections like angle, channel, beam, pipe or flat etc.

Tilt able top roll makes it more convenient to remove rolled shell with ease.
