Hydraulic Decoiler Straightening Machine UPHL2-200B–400B | Yiming, Dongguan, China

Yiming's Hydraulic Decoiler Straightening Machine combines an uncoiler and a leveller in one unit. It flattens thin coil material of 0.3–2.6 mm, such as stainless steel, copper, iron and aluminium, ready for feeding into a press or other downstream line.

It is offered in three models, UPHL2-200B, UPHL2-300B and UPHL2-400B, for strip widths of 200, 300 and 400 mm. Combining both functions saves floor space, and speed is set by variable frequency control.

Key Features

• Uncoiler and leveller integrated in a single machine to save space
• Variable frequency control of levelling speed, adjustable to match the feeding speed
• Levelling rollers made of SUJ2 steel, heat treated to about HRC60, hard chrome plated and ground
• Floating four-point balance fine adjustment with dial indicator for finding the levelling position quickly
• Auxiliary support wheels can be fitted to stop the levelling rollers bending under pressure and to improve flatness
• Coil arc detection uses metal induction plus photoelectric sensing, suited to coated materials
• Pneumatically liftable levelling section; hydraulic expansion available for the main shaft
