Hydraulic roller bender

A hydraulic roll bender bends angle steel, channel, flat bar, tube and round bar into rings, arcs and spirals. All three rollers are hydraulically driven, the side rollers lift under hydraulic control, and one machine covers the section family your shop actually rolls.

Machine features

  • Full hydraulic drive, electrical centralised control and digital display — pre-bending, rolling and calibrating are completed simultaneously after loading
  • The three rollers are all active rollers, powered by hydraulic motors, rotating forward and reverse
  • The lifting of the two lower rollers is a hydraulic roller device, which effectively controls the deformation of the profile and the rolling accuracy
  • Different moulds can be equipped according to the cross-sectional shape of different profiles
  • Can be installed vertically or horizontally; for high-precision profile rolling, a four-roller structure with a clamping device can be used
  • Full-automatic transmission, compact structure, high reliability
  • Three-roller transmission is not easy to slip — thin-wall material can also be bent
  • The rollers on both sides are distributed asymmetrically, reducing the linear part; both sides of the side roller can be used for feeding the workpiece
  • Double-footplate switch with an emergent stopping system for convenient operation
  • Stable drive — only regulate the side roller up and down to get round, arc or spiral shapes of different curvatures
  • Changing the mould shape processes angle iron, flat steel, round steel or other special shaped material
  • Avoids the shortcomings of making super-large tube bending moulds when bending large-radius shaped material — a necessary complement to single-head and double-head tube benders
  • High speed and high benefit — adapted for middle or large batch production

Advantages in practice

  • Pre-bend, roll and calibrate in one loading — the profile is not re-handled between operations
  • Digital display of roller position makes repeat radii a setting, not a craft skill
  • The asymmetric side rollers leave less straight end than a symmetric layout, so less material is wasted per blank
  • One machine covers the section family — angle, channel, flat, tube and bar — which is why it is the machine small and mid shops buy when they need rings "sometimes"
