Abstract
A blanking line including an uncoiler, a first feeder, a slitter, and a shear. A coil of metal is carried by the uncoiler. The first feeder removes the material from the coil and typically includes a leveler for leveling the metal. The metal is fed from the leveler into a looping pit that is located between the leveler and slitter. The slitter feeds and slits the material a predetermined distance and is driven with servo motors. The looping pit acts as an accumulator allowing the metal to hang so the slitter can move metal intermittently into a shear while the leveler runs at a constant rate. The shear cuts the material to a predetermined length corresponding with the distance that the material is fed by the slitter. A measuring wheel may be included to measure the distance that the material is moved by the slitter.
Claims6
In a blanking line having an uncoiler, a first feeder, a slitter, and a shear, a coil of material being carried by said uncoiler, said material extending through said first feeder and into said slitter, a method for blanking said material comprising the steps:
- feeding said material from said coil using said first feeder, wherein said first feeder is a leveler:
- leveling said material within said leveler;
- slitting and feeding said material into said shear using said slitter, said slitter feeding said material a predetermined distance into said shear;
- cutting said material within said shear to a predetermined length corresponding to said predetermined distance that said material is fed by said slitter;
- and
- wherein said uncoiler, first feeder, slitter, and shear are in respective serial order.
A blanking line for use with a coil of material comprising:
- a leveler for removing said material from an uncoiler and leveling said material;
- a slitter for slitting said material and feeding said material into a shear, said slitter feeding said material a predetermined distance corresponding to the desired length of a blank;
- said shear for cutting into blanks;
- and
- wherein said uncoiler, leveler, slitter, and shear are in respective serial order.
