摘要： A cutter head including a cutter body portion having a first outer surface and a second outer surface located inward of the first outer surface. Both first and second outer surfaces are interrupted by a plurality of blade receiving slots which extend inward into the cutter body portion. The first and second outer surfaces are arranged such that an annular projection is formed protruding from the second outer surface and extending to the first outer surface. The annular projection is also interrupted by the plurality of cutting blade slots thus forming a plurality of individual projections. The cutter head additionally includes a clamping ring extending about the cutter body and secured to the annular projection. The clamping ring comprises first and second ring members which together define an inner receiving channel having a form complementary with the form of the annular projection whereby securing the first and second ring members together about the annular projection positions the annular projection in the receiving channel and secures the clamping ring to the cutter body. The cutter head may include a generally concave shaped clamping block which is attached to the receiving channel in the clamping ring. The cutter head may further comprise blade receiving slots wherein the inner end portion of the slots includes a pair of angled blade mounting surfaces. Also included are cutting blades having side portions of a form which is complementary to the angled blade mounting surfaces of the cutter head.
摘要翻译：一种刀头，包括具有位于第一外表面内侧的第一外表面和第二外表面的刀体本体部分。第一外表面和第二外表面都被多个向内延伸到切割器主体部分的刀片接收槽中断。第一外表面和第二外表面被布置成使得环形突起形成为从第二外表面突出并且延伸到第一外表面。环形突起也被多个切割刀片槽中断，从而形成多个单独的突起。刀头还包括围绕刀体延伸并固定到环形突起的夹紧环。夹紧环包括第一和第二环构件，它们一起限定具有与环形突起的形式互补的形状的内部容纳通道，从而将第一和第二环构件围绕环形突出部固定在一起，使环形突起位于接收通道中并确保夹紧环到刀体。刀头可以包括大致凹形的夹紧块，其连接到夹紧环中的接收通道。刀头还可以包括刀片接收槽，其中槽的内端部分包括一对成角度的刀片安装表面。还包括具有与刀头的成角度的刀片安装表面互补的形式的侧部的切割刀片。
