    • A method, and an apparatus, for operating a hydraulic shearing machine are provided comprising for cutting a shearing-movement of at least one shear blade (17) which is curved, starting from a starting-position under application of an overall actuating-force and for resetting of the shear blades which were moved for cutting to their starting-position after accomplishment of the shearing-movement a reset-movement under application of an overall reset-force, the shearing-movement and the reset-movement being accomplished by a hydraulic actuating-mechanism comprising hydraulic cylinders (21, 22, 23, 24) and the overall actuating-force and the overall reset-force being applied to the moved shear blades by at least one hydraulic cylinder of the actuating-mechanism. The magnitude of the overall actuating-force is adjustable by switching one or several hydraulic cylinders of the actuating-mechanism in and out of operation-mode. The method proposes that the position of the curved shear blade are controlled by a control system by regulating the flow of hydraulic fluid to the hydraulic cylinders according to setpoints for a shear blade position versus time function and the overall actuating-force and overall reset- force requirements.

    • An apparatus for punching knock-outs out of light gauge steel framing studs used in building construction to form holes of sufficient size to allow building wiring and piping to extend therethrough includes a compact hand held frame (12) having a generally C-shaped frame portion (14). The C-shaped frame portion has spaced apart ends (16, 18) located along a working axis (20) for receiving a stud (30) therebetween. A punch and die assembly (24) includes a punch (26) and a die (28) mounted opposite each other at the ends of the C-shaped frame portion. An actuatable driving mechanism (36) mounted to the frame is operable to drive the punch and die assembly over a working stroke range between a deactuated position (52) and an actuated position (54). In the actuated position, the punch extends into the die by punching through the stud to produce a knock-out (342).
    • 一种用于在建筑结构中用于形成足够尺寸的孔以便建筑物布线和管道延伸穿过其中的轻型钢框架柱的敲击装置包括具有大致C形框架部分的紧凑的手持框架(12) (14)。 C形框架部分具有沿着工作轴线(20)定位的间隔开的端部(16,18),用于在其间接纳螺柱(30)。 冲头和模具组件(24)包括在C形框架部分的端部处彼此相对安装的冲头(26)和模具(28)。 安装到框架的致动驱动机构(36)可操作以在打开位置(52)和致动位置(54)之间的工作行程范围内驱动冲头和模具组件。 在致动位置,冲头通过冲压穿过螺柱延伸到模具中以产生敲除(342)。
