Abstract
A tip for a rotary debarker has a polygonal main body with a front surface and a rear surface, and at least one cutting blade along each of the opposed edges. The main body includes a non-circular mounting boss extending from the rear surface. The main body is mounted to a tip holder that has a non-circular seat for receiving the non-circular mounting boss. The non-circular mounting boss and seat restrict relative movement between the tip and the holder during cutting operations. The tip is reversible relative to the holder to provide two operative cutting blades per tip.
Claims18
A cutting tip and holder assembly for a rotary debarking machine, comprising:
- a cutting tip having a main body with a front surface and a rear surface, at least two opposed edges with a cutting blade along each of the at least two opposed edges and at least one bore through the main body defining a bore axis, and a non-circular mounting boss extending from the rear surface;
- a holder having a non-circular seat configured for receiving the mounting boss in a first orientation, and for receiving the mounting boss in a second orientation in which the tip is rotated by 180° relative to the holder, said holder further including a shoulder portion, and the cutting tip is mounted to the holder such that one cutting blade is in an operative position and the cutting blade along the opposite edge is in a spaced apart relation to the shoulder.
A cutting tip assembly, comprising:
- a cutting tip defined by a main body having a front surface and a rear surface, at least two opposed edges with a first cutting blade along one the at least two opposed edges and a second cutting blade along the other of the at least two opposed edges, and a non-cylindrical mounting boss extending from the rear surface;
- a cutting tip holder having a non-cylindrical seat configured for receiving the mounting boss;
- wherein said tip is configured for mounting in said holder in a first position with said mounting boss received in said seat such that said first cutting blade is held in an operative position, and said second cutting blade is in a spaced apart relationship with a shoulder member formed on said holder, and wherein said tip is configured for mounting in a second position with said mounting boss received in said seat such that said second cutting blade is held in an operative position and said first cutting blade is in a spaced apart relationship with said shoulder member.
A tip for a rotary debarking machine, comprising:
- a rectangular main body having opposed side edges, opposed top and bottom edges, the top and bottom edges each defining a cutting blade, a front surface and a rear surface, said body having at least one bore formed therethrough from the front to the rear surface and defining a bore axis, and a boss extending from the rear surface, and
- a holder having a seat configured for receiving the boss in a first orientation, and for receiving the boss in a second orientation in which the main body is rotated by 180° relative to the holder, said holder including a shoulder portion that shields a cutting blade when the boss is in both the first and second orientations.
