Carell Industrial Comac 3000 Series 480V Three Phase 3-1/2” Pipe Double-Pinch Hydraulic Angle Roll 307HV

Description

Carell’s Model 307HV 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 in all three axis. 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 pre-bending
• 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 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. 15 HP TEFC electric pump motor
• Multi axis, 6 way, fully adjustable lateral guides, powered in all three directions: (radial, axial thrust and linear up/down movements) on HV4 Versions 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 on “V” version 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 width changes for maximizing production. Shaft single keyed for easy tooling changeover
• Forced lubrication system providing full security under harsh working conditions. All internal moving components have individual Zerk fittings
• Machine operates in both horizontal and vertical positions per your needs
• Mobile control console equipped with pushbuttons for roll positions, dual LED digital readouts to monitor bending roll positions, dual foot pedals for left/right rotation, power On, hydraulic unit On and E-Stop switch for maximum operator safety. Controls in low voltage 24VAC
• Operating and maintenance tool kit, instruction manual provided
