Formtek-Maine shipped a Cut-to-Length and Recoiling Line for processing high-strength low-alloy steel to Mead Metals. The St. Paul, Minn.-based service center specializes in providing coils of specialty, rare and exotic metals in small quantities.
The Formtek-Maine system had to be robust enough to uncoil and straighten coils ranging from 0.135 inches thick at 80,000-psi yield to 0.070 inches at 160,000-psi yield and at line speeds approaching 200 fpm.
The system includes the 4R series stock reel with powered side guide rollers to prevent telescoping of coils and an adjustable sub-base to adjust coil alignment to ensure centered coils.
The coil processor consists of a hold-down peeler station with clamping thread-up table; a model HDC straightener head with individual roll adjustment; a combination edge conditioner/camber compensator; a 2-roll ServoMax servo feed with cartridge-style twist compensator; and hydraulic cutoff shear.
The fixed runout table has a rolling base to manually move the table in line for running in cut-to-length mode, or to move out of line when recoiling. A fixed edge is provided on the table for a quick camber check on cut parts. The recoiler has a full-radius drum mandrel with a manually actuated lead edge locking device on one arm and clearance for fork truck tines cut into the arms to allow loading or unloading of coils. The over-arm roller has a quick release mechanism to allow easy removal of the roller.
