bridge grip feeder |
A type of grip feeder that clamps stock in the center or across its entire width. |
coil |
A long, thin sheet of metal that has been wound tightly. Stock first appears as coil for many press operations. |
coil set |
The natural curvature remaining in coil after it has been unwound. |
conveyor |
A long belt that rotates to remove parts or scrap from the die area. |
cradle |
A type of uncoiler that supports coil from below on its outside diameter. |
eccentric drive |
A powered drive that uses an offset section to power the reciprocating motion of the ram. |
feed gripper |
The device on a grip feeder that clamps/unclamps and slides back and forth to advance stock into the die. |
feed mechanism |
A mechanism designed to intermittently advance stock into the press between strokes. |
feed roll |
A cylindrical component on a roll feeder that rotates to advance stock into the die. |
grip feeder |
A type of feed mechanism that uses one stationary and one sliding clamping mechanism to intermittently feed stock into the press. |
idler roll |
An unpowered component on a straightener that bends stock as it passes through the equipment. Idler rolls are positioned above the stock. |
inside diameter |
An interior cylindrical surface of a hole. |
intermittent |
Moving in a repetitive, constant start-and-stop cycle. |
keeper |
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. |
mandrel |
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. |
outside diameter |
An exterior cylindrical surface of a part or stock. |
pilot |
A long, slender punch with a rounded tip used to position the metal sheet by entering a previously formed hole. |
pinch roll |
A component on a cradle uncoiler that assists uncoiling by pulling on the stock. |
ram |
The main upper portion of the press that slides up and down within the press frame during operation. |
reel |
A type of uncoiler that holds coil by its inside diameter and suspends it above the ground. |
rest roll |
A component on a cradle uncoiler that supports the coil and rotates to unwind the coil. |
retainer gripper |
The stationary device on a grip feeder that clamps and unclamps to assist in advancing stock. |
roll feeder |
A type of feed mechanism that uses rotating rolls to intermittently feed stock into the press. |
scrap chopper |
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. |
shaker |
A special chute that reciprocates back and forth to remove parts or scrap from the die area. |
side plate |
A component on a cradle uncoiler that prevents the coil from tipping on its side. |
slack loop |
Excess stock that hangs between coil-line equipment. The slack loop allows continuous and intermittent equipment to work together. |
straightener |
A mechanism designed to repeatedly bend stock back and forth to remove any natural curvature. |
straightening roll |
A powered component on a straightener that bends and passes stock through the equipment. Straightening rolls are positioned below the stock. |
uncoiler |
A mechanism designed to hold coil and gradually unwind it during press operations. |
