Carell Industrial Comac 3000 Series 480V Three Phase 5” Pipe Double Initial Pinch Universal Roll Bender 308HV

Description

Carell’s Model 308-HV4 is a 3 driving rolls, double initial pinch universal roll bending machine with independent hydraulic adjustment of both lateral bending rolls and hydraulic powered rotation of all three rolls via direct applied hydraulic motors. Lateral guides are adjustable 3 axes, 6 directions. This versatile unit is ideal for rolling standard/special sections plus tube/pipe in mild-structural-stainless steels and a variety of other materials. 

Machine is furnished with a set of universal rolls suitable for bending standard sections including angle iron leg-in and leg-out. These rolls bend flat bar (on flat and on edge), square bar, tees, channel as well as round bar, angles, square and rectangular tube sections. 

Features

• Rugged, rigid, one piece solid steel weldment frame, normalized and precision machined, ample sized access panels and ventilation for internal hydraulic unit
• Larger, high strength steel shafts, heat treated and ground, journaled in dual self aligning spherical roller bearings for optimum performance, loading and efficiency
• Independent hydraulic adjustment of both lower rolls for double prebending with dual speed approach for superior control in positioning
• All 3 rolls driven by direct coupled independent hydraulic motor/planetary reducer groups for near 100% efficiency in torque transmission to the rolls, top shaft protected by hydraulic overload on top drive assembly with speed compensation feature, hydraulic unit integral to the machine and protected by maximum pressure relief valves and return lines. Roll rotation controlled via dual foot pedals
• Hydraulic power unit integral to the machine frame, well ventilated and protected from overload by maximum pressure relief valves and thermal pump motor switchgear with reset control. Solenoid valve bank situated for easy access, coils equipped with LED illumination indicating its activation
• Multi axis, 6 way, fully hydraulic lateral guides, adjustable in all three directions: (radial, axial thrust, and linear up/down movements) for bending angle iron leg-in and leg-out. Positions readable on graduated scales for precise repeat positioning. Cam follower roller can be positioned at different locations along the cylindrical support roller
• Variable speed rotation via digitally driven valves for precision pre-bending and maximum efficiency during general bending or pass through of unbent material
• Universal bending rolls with modular components, hardened and wear resistant. Use of components in various configurations permits bending of most all-standard section types including angle iron leg-in and leg-out. Main components, telescoping, allow swift throat with changes for maximizing production. Shaft single keyed for easy tooling changeover
• Forced lubrication system providing full security in the worst possible working conditions
• Machine operates in both horizontal and vertical positions
• Mobile control console equipped with pushbuttons for all 16 hydraulic machine movements, dual electronic digital readouts to monitor bending roll positions, variable speed control, power on, hydraulic unit on the other controls for maximum operator safety and mobility. Dual foot pedals for left/right roll rotation. Controls in low voltage 24V
• Operating & maintenance tools and instruction manual included
