Rolla-V die with milled groove 12.7 x 19 mm. RVM series in 42 Cr. Max.load 3000 kN/m. Minimum angle 73°.

The Rolla V dies are distinguished from the traditional ones by the presence of 2 oscillating rotors which support the sheet metal before the bending process. Their peculiarity consists in the rotation of the rotors that accompanies the sheet metal during the bending with a drastic reduction of the friction resistance and of the length of the minimum edge. This type of tool applies the concept of tangential bending whereby the behavior of the sheet is different: this is more noticeable if holes and slots are present near the bending areas. Thanks to this concept, these areas do not undergo the classic deformations more commonly known as "slurries".

  • Sheet metal supported during bending process
  • Minimum movement of the sheet metal on the inserts reduces bending marks
  • Internal bending radius is the same of the punch tip radius

HANDLES INCLUDED

In order to facilitate the movement of RVM, RVPV3 and RVHD series, it's possible to mount  specific handles for manual lifting (where the weight permits) or mechanically operated through threaded holes. Thanks to this solution, positioning and removing the die from the press brake is an easy and safe operation.

ACCESSORIES

RVX1: GREASE

RVX1 grease is a lithium lubricant with particular properties. Thanks to its additives it bears the loads of compression. It protects the parts subjected to sliding. Very suitable for preserving the seat of the inserts or rotors and avoiding abrasion. The single pack contains 500 g of grease.

RVX-TAPE: PROTECTION

Fix the RVX-TAPE protections on the dies for those applications where the sheet metal must not show any signs. These are adhesive strips made with composite materials able to resist compression and to maintain a particularly compressible and anti-friction contact surface with the sheet.

RV-TO: ASSEMBLY TOOL

This tool is created to facilitate the release of the spring from its lower pin. Thanks to its shape, the tool allows you to start the operation in absolute safety and to replace worn parts very quickly.
