Saw blade for sawing hollow profiles and form profiles

摘要

A saw blade (1) serves for sawing hollow profiles and form profiles. The saw blade (1) is especially designed as saw band, and it includes a base body (2) and a plurality of teeth (10). The teeth (10) are formed by protrusions (3) and inserts (4). The teeth (10) are arranged in a group being repeated along the saw blade (1). The group includes at least three unset chamfered teeth (10). The group includes a first tooth (C1) having two chamfers (FC11, FC12) being symmetric to the longitudinal center plane (9) of the saw blade (1), a second tooth (C2) having two chamfers (FC21, FC22) being non-symmetric to the longitudinal center plane (9) and a third tooth (C3) having two chamfers (FC31, FC32) being non-symmetric to the longitudinal center plane (9).

1. A saw blade for sawing hollow profiles and form profiles, comprising:
a longitudinal center plane, a base body, and a plurality of teeth, the teeth being connected to the base body and including a cutting portion,
each tooth including a protrusion being connected to the base body and an insert being connected to the protrusion, the protrusion being made of a first material and the insert being made of a second material, the second material being harder than the first material,at least a part of the teeth being arranged along the saw blade in a group, the group being repeated along the saw blade, the group including at least three unset chamfered teeth,a first tooth in the group including a first chamfer and a second chamfer, the first and second chamfer extending symmetrically with respect to the longitudinal center plane,a second tooth in the group including a first chamfer and a second chamfer, the first and second chamfer extending non-symmetrically with respect to the longitudinal center plane, the first chamfer extending in a first direction from the longitudinal center plane and having a first chamfer angle, the second chamfer extending in a second direction from the longitudinal center plane, the second direction being different than the first direction, the second chamfer having a second chamfer angle, the second chamfer angle being greater than the first chamfer angle,a third tooth in the group including a first chamfer and a second chamfer, the first and second chamfer extending non-symmetrically with respect to the longitudinal center plane, the first chamfer extending in the first direction from the longitudinal center plane and having a first chamfer angle, the second chamfer extending in a second direction from the longitudinal center plane, the second direction being different than the first direction, the second chamfer having a second chamfer angle, the second chamfer angle being smaller than the first chamfer angle,the first chamfer of the second tooth and the first chamfer of the third tooth being designed and arranged to end in a first laterally outward common point as seen in a front view of the saw blade, andthe second chamfer of the second tooth and the second chamfer of the third tooth being designed and arranged to end in a second laterally outward common point as seen in a front view of the saw blade.
