Abstract
A plate-shaped shearing knife is provided made of hard metal for shearing off allotments of liquid glass. The hard metal of the shearing knife has a thermal conductivity of at least 85 W/mK. Next to a V-shaped or circular-shaped cutting region -2-, there are edge regions on both sides that do not flare out wedge-like, and have an average width b which is in a range of 5% to 30% of the total width of the shearing knife B in this section.
Claims8
A plate-shaped shearing knife for shearing off allotments of liquid glass, said knife having a plate thickness and being comprised of a hard metal and having a roughly V-shaped or circular-shaped cutting region comprised of said hard metal, said cutting region having a wedge-shaped cross section with respect to said plate thickness of said shearing knife, said hard metal having a thermal conductivity of at least about 85 W/m° K, said shearing knife having on both sides of said cutting region, edge regions not having a wedge-shaped cross section, each edge region having an average width in the range of 5% to 30%″ of the total width of said shearing knife, said wedge shaped cross section having a heavily inclined surface, said cutting region transitioning from said heavily inclined surface into said cutting edge.
