RM1270/90 Roll Bender

Machine description:

• The RM series is designed for standard sheet metal bending work to obtain cylindrical forms. without pre-bending (as standard). For this, the sheet metal is clamped between the central drive shafts. The upper shaft is stationary, the lower one moves vertically to adapt to the desired sheet thickness. Adjustment to the required bending radius is done by moving the side shaft.
• Sheet metal bending is an important work function ensuring the quality of the final part and consists in bending the ends of the sheet metal (pre-bending), which allows obtaining a uniform closed shell. To bend in both directions, unfold the sheet and press the side roller twice).
• The asymmetric design of the roller system allows for pre-bending of the sheet by moving the side roller. Optionally, it is possible to mount an electric drive on the side shaft, which will allow for pre-bending.
• As standard, on the RM series rollers it is possible to obtain a minimum diameter equal to three diameters of the upper roller, when bending metal with a cold yield strength of 260 N/mm ² and bending strength of 24 kg/mm ​​² .
• The upper shaft is foldable, which makes it easier to remove finished products. The folding shaft is equipped with a lock that prevents it from opening spontaneously during operation.

Key advantages:

• Strong welded, steel frame.
• Rollers made of steel with increased tensile strength in accordance with the SAE 1050 quality certificate and hardened and ground.
• Rotating upper and lower rollers driven by an electric motor through a reducer and chain. This ensures stable bending under load and improves productivity.
• Upper roll detachable to the side with a support system.
• Lower and side rolls with height adjustment (manual as standard).
• Rollers equipped with grooves for bending bars.
• RM models provide the possibility of conical bends.
• Optional motorized lifting of the lower and side rolls - ensures pre-bending with the best quality and repeatability.
• Optional digital indication of the position of the motor-driven lower and side rolls.
• Machine manufactured in accordance with the EC Safety Directive (CE mark) / Declaration Compliance.
