Three-roll bending machine for sections and tubes, double initial pinch style (non-symmetrical roll design): stationary upper roll, independently adjustable lower rolls.
Common Characteristics
FUNCTIONAL SPECIFICATIONS
Three driving rolls
Bending rolls with independent hydraulic adjustment for prebending of the leading and the trailing edge of profile
Lateral guide rolls with three-directional movement (axial, radial, angular) and mechanical adjustment, complete with anti-twisting cam roller for leg-in angle bending
Overhead attachment for calibration of diameter and control of pitch of pipe coils: the assembly features two movements, one in the radial direction for diameter calibration managed hydraulically and one in the axial direction for pitch control, mechanical adjustment manually operated.
The range of OD is 300 through 1.400 mm
two-axis programmable position controller, PLC based, for automatic control of the bending rolls
Two adjustment speeds of bending rolls: fast approach at high speed and accurate final positioning at slow speed
Position of rolls referenced with linear encoders, 0.1 mm accurate
Controls actuated via remote free-standing console
Horizontal-vertical working position combination
