Machining flat or three-dimensional coils with small tube diameters

THE coil bending system 4-Runner H1 is dedicated to difficult machining of flat or three-dimensional coils with small- sized tube diameters. Dimensions are important in such components, so the main goal of the 4-Runner H1’s design, starting from the bending head, was to reduce the dimensions as much as possible, to allow the production of components that could not be manufactured previously. As part of the latest generation of completely electrical systems, the 4-Runner H1 bends by flexing right and left in process, and is multi-radius capable, with the possibility of variable radius. It can be easily integrated with a Smart bender to produce a complete system, which the BLM Group refers to as ‘bending with mandrel from coil’. All of the 4-Runner H1’s movement axes are electrical, including the blocking and support. Calibration of the equipment is easily performed thanks to the torque control, and saved with the part program. With no mechanical adjustments, maximum repeatability of parts during bending operations and tube forming is ensured, with measurement in real time. VGP3D programming software for tube benders by BLM Group can also be used in the 4-Runner H1. Three-

BLM’s 4-Runner H1

brushless motors control the rotation and movement of the cutting wheel, ensuring precision and process repeatability. 4-Runner H1 is an I4.0- compatible system. BLM SpA specialises in the production of CNC tube-bending machines, end forming, wire bending equipment and related automation devices.

dimensional graphic programming of the piece is made simple and intuitive, and a simulation of the execution avoids multiple attempts during the production stage. In order to supply the coil, the 4-Runner H1 is equipped with a new reel with clutch, which allows it to work in neutral with commands inserted directly by the work program. Orbital cutting, both internal (4RIPC) and external (4RC), on the 4-Runner H1 is also completely electrical. Two for bending profiles with high flexion strength modulus; and Taurus for bending aluminium profiles and heavy metal fabrication work. The company’s dished heads production lines include technologically advanced presses, flanging machines and manipulators that offer reliability in terms of achieving tolerances and lamination reduction. Hydraulic presses (PPM) ensure forming accuracy, and automatic manipulator (MA) handling systems allow processing of several plates at the same time. Flanging machines (BF) offer high productivity and quality of the final product, and the hydroforming machines (PPH) are used in the production of dished heads for truck tanks.

A par tner in metal bending FOR over 50 years, Faccin SpA has assisted manufacturers around the world to achieve challenging projects. The company produces and sells a wide range of bending machines, including three models for bending thin plates: HCU two-roll bending roll with high speed and productivity; ASI three- roll initial pinch bending roll; and 3HEL electronic three-roll pyramid bending roll with double pinch. For rolling thicker plates, two different models are available: 4HEL, a four-roll pyramid electronic bending roll; and HAV, a three- roll variable geometry bending roll.

Faccin has also developed a range of special machines for specific needs in the fields of pipe production, shipbuilding and aerospace. These include the long three-roll bending rolls of the HAV-2F range, suitable for use in pipe mills; FB angle rolls for bending bulbs and various profiles; PPS Shipbuilding presses for metal forming, levelling, bending, curving and 3D modelling; large-sized RP bending rolls that combine the speed of a bending roll with the versatility of a press brake; and the R line levellers for processing plates of any length, up to 4m wide and up to 70mm thick.

Faccin also constructs and markets various types of angle rolls that ensure bending quality and productivity over time: RCMI, specifically designed
