Definitions
- a flying shear adapted to be installed in the shearing line at the finished end of the heavy plate rolling mill plant for shearing metal plates in various lengths, having a stationary outer housing mounted on the bed plates, a pair of upper knife holder drives which are mounted on the outer housing and drive an eccentric cam shaft joumaled on the outer housing for lifting and lowering an upper knife holder, a shiftable inner shear housing moving parallel to the traveling stock and being disposed inside of the outer housing, thev inner shear housing guiding the liftable upper knife holder and carrying a lower knife holder to effect a shearing action between the upper knife holder, a pair of shifting supports bearing on the outer housing for supporting the inner shear housing, and a pair of shifting drives mounted on the bed plates for reciprocating the inner shear housing in synchronism with the traveling stock at the time of cutting.
- the upper knife holder is adapted to reciprocate both elevationally and laterally, and is connected to the eccentric cam shaft for rotating the output shaft of the upper knife holder driving device that is arranged in a stationary manner by a connecting rod.
- the desired sectional length of stock is provided by the simple structure of the fly- PATENTEDIAm m4 sum 01 or 24 in PRIOR ART FIG.
