Roll forming machine
This belongs to four roller plate rolling machine, up roller is fixed and it is the main drive, hydraulic motor driven by variable speed drive gear up and down roller belt drive, to provide torque for the roll sheet; Under the roller moves vertically through the hydraulic pressure acting on the piston of hydraulic cylinder obtained in order to clamp plate for hydraulic transmission; The down roll of the sides with side roller and cylinder driven by oil. The machine advantage of end plate bending (pre-bending) and rolling can be conducted on the same machine
The 4 roll plate bending machine is the easiest one, thanks to a frame designed to satisfy every kind of needs. Advantages are various:
Pre-bending is highly reduced because the material gets pinched by in between the two central rolls.
Working can be made in one only pass, following the steps here below:
1. Squaring
2. Pre-bending
3. Bending
4. Closing pre-bending
The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the side roll (D).
The plate is squared thanks to the position that the side roll (C) takes.
The space to the limit of the machine reduces to one side only, thanks to the possibility of squaring and bending in one only step.
We advise a 4 roll plate bending machine:
For a high and massive production
For the possibility to control by NC
For the possibility to make conical bendings
