摘要： A multi-piece die section for a press brake installed rotary bending tool in which a forming anvil is positioned in a holder in accordance with the thickness of material to be bent so that the rotary bender and press brake operate on the same center line. In one version of the holder a forming anvil is adjustably positioned relative to the center line of the rotary bender and in a second version thereof the forming anvil is precision sized in accordance with the thickness of the work material whereby to eliminate the need for shims and readjustment of press ram stroke as required by the first version.
摘要翻译：一种用于压制机安装的旋转弯曲工具的多件式模具部分，其中根据要弯曲的材料的厚度将成形砧定位在保持器中，使得旋转弯曲机和压制机在同一中心线上操作。在保持架的一种形式中，成形砧相对于旋转弯曲机的中心线可调节地定位，并且在其第二形式中，成形砧座根据工件材料的厚度精确地定尺寸，从而消除对垫片的需要，按照第一版的要求重新调整冲压柱冲程。

摘要： A compensating bolster and die holder combination for use with the bed of a press brake to provide vertical adjustment and compensating camber to the die holder supported thereby. The die holder is vertically moveable in an open channel of an underlying elongated bolster fitted to the bed of the press; with plural wedge members, moveable transversely of the die holder, serving to adjustably position and support the latter. Each wedge member has joined thereto an indicator pin extending through one side of the bolster which operates to visually indicate the adjusted position of its wedge member; while the several indicator pins cooperate to show the relative adjusted positions of the several wedge members and the consequential adjusted elevation of the die and die holder.
摘要翻译：用于与压制机的床一起使用的补偿垫圈和模具座组合件，用于向由其支撑的模具座提供垂直调节和补偿弯度。模具座可垂直移动到安装在印刷机床上的下面的细长垫片的开放通道中; 具有多个楔形构件，其能够横向于模座保持器移动，用于可调节地定位和支撑后者。每个楔形构件已经连接到其上延伸穿过该摇枕的一侧的指示销，其操作以在视觉上指示其楔形构件的调节位置; 而几个指示针合作来显示几个楔形构件的相对调整的位置以及随后调节的模具和模座的高度。

摘要： A rotary bending tool holder, particularly useful in a press brake type press, which embodies a two piece holder, namely a main body and clamp; usually attached to the moveable ram of the press brake. A rotary bending tool used with the holder is provided with elongated rectangular keyway slots along opposite sides which are aligned to received opposing tabs or keys engageable with such slots. One key is formed on the clamp of the holder while the other key is formed on the main body of the holder. Once positioned in the holder, the clamp is tightened to engage its associated key in one of the slots of the bending tool. This action causes the other key on the holder body to engage the other slot of the bending tool. At the same time opposing surfaces on the holder body and bending tool, located at the same distance from the center line of the tool holder engage to precisely align the center of the rotary head on the center line of the holder and press head.
摘要翻译：一种特别适用于压制机式压力机的旋转弯曲工具架，它体现了一个两件式的保持架，即主体和夹具; 通常连接到压力制动器的可移动的压头。与保持器一起使用的旋转弯曲工具沿着相对的侧面设置有细长的矩形键槽，其与接收的相对的接片对准或与这些槽接合的键。一个键形成在夹持器的夹具上，而另一个键形成在保持器的主体上。一旦定位在保持器中，夹紧器被紧固以将其相关联的键接合在弯曲工具的一个槽中。该动作使保持器主体上的另一个键接合弯曲工具的另一个槽。同时，位于与刀架中心线相同距离处的保持器本体和弯曲工具上的相对表面接合，以将旋转头的中心精确对准在保持器和压头的中心线上。
