2-in-1 Uncoiler Straightener USHL-150–400 | Yiming, Dongguan, China

Yiming's 2-in-1 Uncoiler Straightener (USHL series) combines a coil decoiler and a roller straightener in one unit. It flattens thin strip such as stainless steel, copper, iron and aluminium coil before it goes into a press or stamping line.

The series is offered in four models for strip widths of 150, 200, 300 and 400 mm. Building uncoiling and levelling into a single machine saves floor space, and a frequency converter lets the levelling speed be matched to the feed speed.

Key Features

• Uncoiler and leveller integrated in one machine to save space
• Straightening wheels made from imported SUJ2 steel, heat treated to HRC60, hard chrome plated and ground for an even coating and consistent cylindricity
• Floating four-point balance fine adjustment with a dial indicator for quick levelling
• Optional auxiliary support wheels inside the leveller stop the correction rollers bending under pressure and help improve flatness
• Upper and lower rollers driven through universal joints and gears, avoiding the power loss and surface scratching of passively rotating rollers
• Frequency converter controls the levelling speed, adjustable to suit the feeding speed
• Rack expansion is manual, with inductive rack or photoelectric sensing

Frequently Asked Questions

• What materials and thicknesses can it straighten? It is designed for thin strip such as stainless steel, copper, iron and aluminium, from 0.1 to 0.6 mm thick.
• What coil sizes and weights does it take? Coils up to 1,000 kg with an inner diameter of Ø450–530 mm; outer diameter is Ø1,000 mm on the USHL-150 and Ø1,200 mm on the larger models.
• How fast does it run and how is speed set? Levelling speed is 0–12 m/min, set by a frequency converter and adjustable to match the feeding speed.
• What should I send for a quotation? Send the material type, strip width and thickness, coil weight and diameters, required line speed, and the press or feeder it will supply.
