摘要： A die actuator for moving an operating lever of a threading die on automatic screw machines, and the like, having a turrethead indexable through a plurality of different work positions and slidable along a work axis toward and away from the workpiece. The die actuator comprises a base which is fixedly secured to the bed of the automatic screw machine and defines vertical guide means. An actuator slide is mounted for vertical sliding movement on the base in said guide means between an elevated, upper position and lower, rest position. Lift means extends outwardly of the slide into the path of travel of the operating lever on the threading die as the die moves during indexing of the turret. ENgagement between the lift means and the die operating lever during turret indexing causes the lever to close the die and move the thread chasers into position ready for cutting threads on a workpiece. When the head is subsequently moved forward toward the workpiece, the operating lever moves out from under said lift means and the actuator slide drops downwardly to the rest position out of the way of the turrethead and any of the other tools mounted thereon.
摘要翻译：一种用于使自动螺丝机等上的穿线模具的操作杆移动的模具致动器，其具有能够通过多个不同的工作位置可转位并且可沿工作轴线朝向和远离工件滑动的转盘头。模具致动器包括固定地固定到自动螺丝机的床上的底座，并且限定垂直导向装置。安装致动器滑块，用于在所述引导装置的基座上在升高的上部位置和下部静止位置之间进行垂直滑动运动。提升装置在转台的转位过程中随着模具的移动，将滑动件向外延伸到操作杆在螺纹模具上行进的路径中。在转塔分度过程中，提升装置和模具操作杆之间的结合导致杆关闭模具并将线锯移动到准备好在工件上切割螺纹的位置。当头部随后朝向工件向前移动时，操作杆从所述提升装置下方移出，并且致动器滑块向下移动到静止位置，不在转塔头和安装在其上的其它工具之外。

摘要： A series of individual single tooth thread cutting tools are rotated concurrently about the axis of a pipe and are applied in cutting relation thereto in succession, at the same starting point, by movement radially of the pipe in a time delay relation to each other. They are maintained in cutting relation concurrently until they advance near to the end of the portion to be threaded. They are then retracted from the pipe in succession in the same order in which they were engaged with the pipe, in the same time delay relation to each other, all at the same location endwise of the pipe and substantially the same location circumferentially of the pipe.
摘要翻译：一系列单个单根螺纹切削工具绕管的轴线同时旋转，并且在相同的起始点处以相互间的延时关系沿着管道径向移动而连续地与其相切地施加切割关系。它们同时保持切割关系，直到它们靠近待螺纹部分的末端前进。然后，它们以与管道接合的相同顺序连续地从管道中缩回，并且在相同的时间相互延迟的关系中，全部位于管道的相同位置处，并且管道的周向基本相同的位置。

摘要： An insert chaser die head having a main frame member to which is attached a control plate having at least one guiding groove on its front face and rotating plate means positioned adjacent said control plate. The rotating plate means has at least one bore therein for supporting an actuating pin member whose end travels in the guiding groove and is biased by a spring located in the groove. At least two more bores are formed in the rotating plate for supporting at least two driven pin members, so that a portion of the ends of the pin members protrude from the rotating plate means. A stationary body member mounted adjacent the rotating plate means has at least two channels for slidably supporting at least two carrier members which, in turn, support individual chasers for cutting threads on workpieces. Individual guideways communicating with each channel are formed in the body member to permit the ends of the driven pin members to pass therethrough and engage cam grooves in the carrier members such that, upon rotation of the rotating plate means, the carrier members are moved toward or away from each other.
