3 roll bending machines

Innovation and automation in sheet metal calendering

The three-roll bending machines are hydraulic bending machines, characterized by a robust structure made with numerically controlled machines. They are designed with an increased size of the hydraulic circuit and internal components aimed at withstanding heavy use, prolonging the life of the machine and reducing maintenance.
All the rolls are induction hardened and the separate and mobile control desk on wheels allows the operator to better supervise the bending operations. The push-button controls allow the movement of the lateral rolls, rotation and their inclination to achieve conical bending, while the parallelism of the rolls is managed hydraulically.

THE IMCAR LINE

3RHT

The 3RHT three-roll bending machine is part of the hydraulic bending machines, characterized by a robust structure, machined with numerically controlled machines. The structure and components are designed to withstand heavy use over a long period of time with reduced maintenance.
The variable geometry makes it a very flexible and easy-to-use solution, mainly suitable for the bending of large thicknesses and conical production.
Furthermore, its configuration allows the quick change of the upper roller, allowing its capacities to be further expanded, highlighting its great flexibility.
Its high performance and ease of pre-bending operations allow to obtain flat parts less than 2 times the thickness.

Features

- Wide range of thickness and materials: adjustable geometry by using the independent movement of each roll.- It allows to keep the plate always horizontal even during the pre-bending phase, preventing it from slipping off or tipping over.

Advantages

- Possibility to replace the top roll: quick and easy replacement of the top roll (for a second range of thickness).- Saving on the foundation costs as the variable geometry, working with horizontal side rolls, has a lower height comparing to traditional 3 and 4 rolls.
THE IMCAR LINE

SIHR

The SIHR plate bending machine is a 3-roll bending machine with pre-bending characterized by a robust structure, worked with numerically controlled machines.
All the rolls of the machine are induction hardened and the planetary movement of the bending rolls with reduced interaxis allows to reduce the flat part as much as possible, obtaining an excellent pre-bending.
The control desk is separate and mobile on wheels and allows the operator to better supervise the bending operations. The button controls allow the movement of the lateral rolls, the rotation and their inclination to carry out the conical bending.
The presence of extended shafts makes it versatile in its use, in fact, it offers the possibility of bending the most common profiles by mounting profile bending dies at its ends.

Features

- Planetary movement of the bending rollers with reduced interaxis to reduce the flat part (pre-bending) as much as possible. - Double hydraulic motorization coupled with epicyclic reducers for the rotation of the 3 rollers.

Advantages

- Hardened rollers as standard. - Extended shafts for the use of profile bending rollers. - Hydraulic inclination of the lateral rollers for conical bending.
