Abstract

Apparatus for mounting a notching blade assembly specifically for use in a double-cut die set of the type used to cut tubing continuously emanating from the tube mill. The present invention is directed toward the notching blade assembly used in conjunction with the vertical guillotine blade of the cut-off die set to notch the upper surface of the tubing prior to the shearing cut. The subject device includes a clamp plate secured to the carriage of the double-cut die set, a key-shaped transverse bore extending through the clamp plate and carriage body so that the notching blade having a corresponding key-shaped bore can be placed betwen the clamp plate and carriage, a locking stud having a locking pin on one end thereof is inserted through the key-shaped transverse bore and rotated away from the channel groove portion of the keyhole-shaped bore to clamp the notching blade between the clamp plate and carriage assembly.
