KNIFE ASSEMBLY

A knife assembly (P2) for use in a veneer cutting machine such as a rotary veneer lathe and a veneer slicer includes a knife blade (7)， a knife blade holder (9) and a knife adjusting bolt (15) with a lock nut (13). The knife blade holder (9) includes a holder block (9A) having formed therethrough a threaded hole (9D) through which the knife adjusting bolt (15) is adjustably inserted. The holder block (9) has a first support surface (9B) that is in supporting contact with a part of one surface (7D) of the knife blade (7) on the side thereof where a bevel face (7B) of the knife blade (7) is formed and a second support surface (9A) that is in supporting contact with a part of a base end surface (7F) located opposite from and extending parallel to a cutting edge (7C) of the knife blade.

本数据集涉及一种用于旋切单板车床（rotary veneer lathe）及单板刨片机（veneer slicer）等单板切割机的刀组件（P2），该组件包含刀片（7）、刀夹（9）以及带有锁紧螺母（13）的调刀螺栓（15）。刀夹（9）包括夹块（9A），夹块（9A）贯通开设有螺纹孔（9D），调刀螺栓（15）可调节地穿设于该螺纹孔中。夹块（9）设有第一支撑面（9B）与第二支撑面（9A）：第一支撑面（9B）与刀片（7）的刃口斜面（7B）成型侧的表面（7D）局部区域形成支撑接触；第二支撑面（9A）则与刀片（7）的基端面（7F）局部区域形成支撑接触，该基端面（7F）与刀片切削刃（7C）相对且平行于该切削刃延伸。
