摘要： A pair of hydraulic stabilizing cylinders are supported on a common frame parallel to the main pneumatic drive cylinders driving counter-blow hammer impellers. The stabilizing piston within each stabilizing cylinder is connected to its adjacent impeller. Those ends of the respective stabilizing cylinders adjacent the impeller are connected to the opposite ends of the other stabilizing cylinders by fluid filled hydraulic lines. Because the cylinders and pistons are the same size, as the impellers move, fluid is transferred from one end of each cylinder to the other end of the other. However, should the impellers not move in synchronism toward their point of impact, that impeller tending to move ahead of the other will experience resistance from the fluid in the stabilizing system which tends to keep the impellers in step. In addition, means is provided to detect differences in position of the synchronizing pistons. Any difference in the relative positions of the synchronizing pistons is used to operate the appropriate one of valve operating switches regulating feed of air from an air supply to the air cushion at the retraction end of the main pneumatic drive cylinder. The added air repositions the drive piston in the more retracted position to correct any tendancy for the impellers to start out of step.
摘要翻译：一对液压稳定缸支撑在与驱动反吹锤叶轮的主气动驱动缸平行的公共框架上。每个稳定缸内的稳定活塞连接到其相邻的叶轮。靠近叶轮的相应的稳定缸的端部通过流体填充的液压管线连接到其它稳定缸的相对端。因为气缸和活塞的尺寸相同，所以当叶轮移动时，流体从每个气缸的一端传递到另一端的另一端。然而，如果叶轮不能同步地向其冲击点移动，则倾向于向前移动的叶轮将经历稳定系统中的流体阻力，这趋向于使叶轮保持步进。此外，提供了用于检测同步活塞的位置差异的装置。使用同步活塞的相对位置的任何差异来操作适当的一个阀操作开关，该操作开关调节在主气动驱动气缸的后退端从空气供应到气垫的空气供给。增加的空气将驱动活塞重新定位在更缩回的位置，以校正叶轮开始失步的任何倾向。

摘要： A power hammer with opposed movement of a ram and a bolster. The hammer has a stationary main frame accommodating, with provision for vertical displacements, a power frame. A bolster supporting a blank is attached to the power frame. Also, attached to the power frame is an actuating cylinder provided with a space above its piston serving as a gas chamber, a space below its piston filled with a fluid, and a piston rod carrying a ram with a top die. The hammer also incorporates a mechanism for accelerating the power frame by an additional force equal to, or exceeding by a specified amount, its weight. The mechanism includes spaces provided in the lower portion of the power frame and communicating with the space below the piston of the actuating cylinder, as well as vertical plungers extending inside each of the lower portion spaces and resting on the main frame. An arrangement like this one allows employing the hammer for forging components of various type and size by making use of blow energies varying over a substantially wide range.

摘要： A method of forming a gear through cold plastic working comprises preparing a disc-like blank, and pressing conically a central portion of the blank with a uniform pressure from upper and lower sides to cause plastic deformation in the blank thereby to form a gear along a gear-shaped die arranged around the periphery of the blank. The blank material is restrained to flow radially at peripheral end faces of the blank during the forming of the gear.

摘要： A high-speed pressing machine comprises a receiver filled with compressed gas. A piston with the piston rod at which end there is fixed a crossbeam with the working tool, and the piston moves in a central portion of the receiver space. Power cylinders are provided to return the crossbeam with the working tool to the initial position and are rigidly fixed within the receiver space. This permits cutting the time between the tool operations and raising the number of work cycles of the machine per time unit.
