Document Type and Number:
Japanese Patent JP2933650
Kind Code:
B2
Abstract:
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 guide member mounted to a cross slide assembly affixed to a double cut die set, having a notching blade holder displaceably mounted to the guide member allowing the holder to be positioned at any point along the guide member. The invention further includes an adjustment screw mounted in a base and threadably coupled to the notching blade holder, whereby rotation of the adjustment screw can be used to vary the position of the notching blade holder on said guideway. The subject device further includes a notching blade mounted in a notching blade cartridge, when the cartridge is retained in a chamber on the notching blade holder said chamber having slots cut rearwardly of the body of the chamber allowing the notching blade and notching blade cartridge to be forced back into the holder assembly thus avoiding a failure should the vertical or guillotine blade be broken and left in the die set.
