ABSTRACT:
In accordance with the present invention, a punching assembly is provided. The punch assembly preferably includes a casing or sleeve in which a punch is mounted for longitudinal sliding movement. In accordance with one feature of the invention, a stripper plate is provided adjacent the operating end of the punch. The stripper plate includes a central opening for the punch that surrounds and guides its cutting end. A retaining means is preferably provided to cover a portion of the stripper plate at times to keep the stripper within the assembly until it is to be released. The punch is provided with three longitudinally spaced apart bearing surfaces including a first bearing surface between the bore of the sleeve and a tang at the top of the punch assembly, a second bearing surface between the bore of the sleeve and a mating portion of the punch and a third bearing surface between the stripper plate and the operating end of the punch to thereby distribute loads, minimize wear on the punch and further improve operating precision. An additional feature of the inventiion concerns a punch lubrication trough and lubricating system.
