摘要： In a multistage forming machine, an apron is screwed to a press slide. At its upper end, the apron has six elongated clamping cams, distributed over its width, while four upwardly projecting clamping lugs are fitted at is lower end. Suspended in the apron is a combined tool block with a wedge-shaped supporting plate. Four clamping lugs, distributed over the width, are formed at the upper end of the supporting plate, while four clamping cams are formed at the lower end. The clamping lugs of the combined tool block are suspended by means of the clamping cams of the apron, while the clamping cams of the combined tool block are inserted between the clamping lugs and the main part of the apron. By means of two clamping devices, a clamping force acting in the vertical direction of the combined tool block is produced, bringing about a clamping of the combine tool block and the press slide in the horizontal direction.
摘要翻译：在多级成型机中，将围裙拧到压片上。在其上端，围裙具有六个细长的夹紧凸轮，分布在其宽度上，而四个向上突出的夹紧凸耳安装在下端。悬挂在围裙中的是具有楔形支撑板的组合工具块。分布在宽度上的四个夹紧凸耳形成在支撑板的上端，而在下端形成四个夹紧凸轮。组合的工具块的夹紧凸耳通过围裙的夹紧凸轮悬挂，而组合的工具块的夹紧凸轮插入夹紧凸耳和围裙的主要部分之间。通过两个夹紧装置，产生沿着组合的工具块的垂直方向作用的夹紧力，从而使得组合工具块和压板在水平方向上的夹紧。

摘要： A machine with a cutting device includes a stationary bar-cutter blade and a slicing blade which cooperates with and is displaceable in relation to the bar-cutter blade. The slicing blade is a closed circular blade. The bar-cutter blade is a half blade and cooperates with a centering and clamping piece, which is displaceable in relation to the bar-cutter blade, to form together a slotted round blade. The centering and clamping piece can be controllably displaced between a centering position, in which, during operation, the bar to be cut is centered without clamping of the bar; a released position, in which the centering and clamping piece is completely removed from the bar, and a clamping position, in which the centering and clamping piece clamps the bar.

摘要： A method and apparatus achieve the intermittent feeding of raw material into a shearing station by exerting a drive torque on draw-in rollers in order to effect their rotation in one arcuate direction and hence the movement of the raw material toward the shearing station. A counteracting torque, which is less than the drive torque, is continuously exerted on the draw-in rollers. Thus, during intervals following a shearing operation when the drive torque is terminated, the counteracting torque functions to reverse the rotation of the draw-in rollers and hence retract the sheared end of the raw material away from the shearing station.
摘要翻译：一种方法和装置通过在牵引辊上施加驱动扭矩来实现原料进入剪切站的间歇进给，以便在一个弧形方向上实现其旋转，从而使原料朝向剪切工位移动。小于驱动扭矩的反作用力矩连续施加在牵引辊上。因此，在驱动扭矩终止后的剪切操作之间的间隔期间，反作用扭矩用于反转牵引辊的旋转，从而使原材料的剪切端远离剪切工位。

摘要： The ejector pin for ejecting a workpiece from a die of a stamping machine is actuated by means of a cam shaft oscillated back and forth on the machine frame through less than one revolution, a radial cam mounted on the shaft, and a motion transmitting rocker carrying a cam follower. The stroke of the ejector pin can be set by angularly shifting the position of the cam on the shaft, the angular length of the cam shaft being greater than the angular spacing of the terminal shaft positions. The portion of the cam face first engaged by the cam follower during the working stroke of the ejector pin spirals uniformly outward from the cam shaft axis to an outermost position which is reached before the cam shaft movement stops.
