ABSTRACT:
A flying ram cutoff machine for severing successive lengths of an elongated workpiece continuously moving in the direction of its longitudinal axis employs a bevel gear drive for swinging a ram in synchronization with movement of the workpiece. A motor drive fly wheel and clutch assembly power a drive shaft which extends parallel to the longitudinal axis of the workpiece, at the rear of the machine. A pair of bevel gears disposed at spaced locations along the drive shaft form power take-offs for transmitting power from the drive shaft to a pair of input shafts which extend perpendicularly away from the drive shaft and toward the swingable ram. A pair of crank assemblies couple the input shafts with the ram to produce swinging movement of the ram upon rotation of the drive shaft. Backlash of the drive system is controlled by interposing a stabilizing spacer between one of the bevel gears and a stationary support. The drive system may be interchangeably employed with either horizontal or inclined type rams, and exceptionally long rams may be driven without the need for idler gears or the like.
