High-precision two-roller rolling machine-for small-diameter surface without trace rolling
The upper roll of the two-roll hydraulic automatic rounding equipment is a steel roll, and the lower roll is a steel roll core covered with an elastic layer. The plate is placed between the two rolls. By adjusting the distance between them, make it contact-pressurize-the lower roll deforms, and the plate deforms accordingly. , the two rollers rotate to continuously bend the sheet into pipe fittings of required specifications.
