bridge grip feeder
A type of grip feeder that clamps stock in the center or across its entire width.
A long, thin sheet of metal that has been wound tightly. Stock first appears as coil for many press operations.
The natural curvature remaining in coil after it has been unwound.
A long belt that rotates to remove parts or scrap from the die area.
A type of uncoiler that supports coil from below on its outside diameter.
A powered drive that uses an offset section to power the reciprocating motion of the ram.
The device on a grip feeder that clamps/unclamps and slides back and forth to advance stock into the die.
A mechanism designed to intermittently advance stock into the press between strokes.
A cylindrical component on a roll feeder that rotates to advance stock into the die.
A type of feed mechanism that uses one stationary and one sliding clamping mechanism to intermittently feed stock into the press.
An unpowered component on a straightener that bends stock as it passes through the equipment. Idler rolls are positioned above the stock.
An interior cylindrical surface of a hole.
Moving in a repetitive, constant start-and-stop cycle.
A component on a reel uncoiler that prevents the coil from sliding off the mandrels.
loop control device
A device that detects when stock must be advanced to maintain the slack loop. Either a powered uncoiler or straightener will typically have a loop control device.
A component on a reel uncoiler that holds coil through its inside diameter. Mandrels expand to hold the coil in place.
mechanical roll feeder
A roll feeder that is powered with energy supplied by the press itself. Mechanical roll feeders require rods connected to the press eccentric drive.
open-throat grip feeder
A type of grip feeder that clamps stock on one edge. Open-throat grip feeders can accommodate wider stock.
An exterior cylindrical surface of a part or stock.
A long, slender punch with a rounded tip used to position the metal sheet by entering a previously formed hole.
A component on a cradle uncoiler that assists uncoiling by pulling on the stock.
The main upper portion of the press that slides up and down within the press frame during operation.
A type of uncoiler that holds coil by its inside diameter and suspends it above the ground.
A component on a cradle uncoiler that supports the coil and rotates to unwind the coil.
The stationary device on a grip feeder that clamps and unclamps to assist in advancing stock.
A type of feed mechanism that uses rotating rolls to intermittently feed stock into the press.
A mechanism designed to cut scrap into smaller sections to facilitate handling.
servo-driven roll feeder
An independent roll feeder that has powered, computer-controlled rolls.
A special chute that reciprocates back and forth to remove parts or scrap from the die area.
A component on a cradle uncoiler that prevents the coil from tipping on its side.
Excess stock that hangs between coil-line equipment. The slack loop allows continuous and intermittent equipment to work together.
A mechanism designed to repeatedly bend stock back and forth to remove any natural curvature.
A powered component on a straightener that bends and passes stock through the equipment. Straightening rolls are positioned below the stock.
A mechanism designed to hold coil and gradually unwind it during press operations.
