摘要： The invention relates to a method for the manufacture of an annular article, which substantially consists of metal, ceramic material, and/or polymer. A cavity in a die is filled with a formable working material, which shall form said article. A tubular, upper punch (17) is introduced into the upper mouth of a hole in a die (34), so that a closed mould cavity is formed. The upper punch and a lower punch (27) are simultaneously struck towards one another at such a high velocity that the working material is plasticized and flows out and fills the mould cavity, and thereafter the upper punch is removed. Then, a mandrel (35) in the lower punch is driven out of the annular body by means of a mandrel expulsor (170), which is pressed against the mandrel from above, and thereafter the annular body is from below pushed out of the die by mean of the lower punch. The invention also relates to an equipment for the carrying out of the method.
摘要翻译：本发明涉及一种用于制造基本上由金属，陶瓷材料和/或聚合物组成的环形制品的方法。模具中的空腔填充有可形成的工作材料，其将形成所述制品。将管状上冲头（17）引入模具（34）中的孔的上口，从而形成封闭的模腔。上冲头和下冲头（27）以如此高的速度朝向彼此同时撞击，使得加工材料被塑化并流出并填充模腔，然后去除上冲头。然后，下冲头中的心轴（35）借助于从上方压靠心轴的芯棒展开器（170）从环形体驱出，之后将环形体从下方推出模具通过下冲击。本发明还涉及一种用于执行该方法的设备。

摘要： The machine disclosed herein is known as a high velocity impact forming machine. It is provided with two tooling or anvil members and associated equipment assembled in such manner that no multiple pounding or restrike results as the machine is used. The machine has adjusting means for adjusting the energy output from stroke-to-stroke, thus enabling the user to use a sequence of varying energy forming steps such as breaking scale in hot work, preforming, and blocking. Means is provided by which the tooling is separated immediately after forming so that handling of the formed parts can commence immediately and without pause. Operation cycle time is thus used most efficiently. The structure of the machine is such that relatively low and fully controllable foundation loadings result. The machine can be provided with sufficient die area to accommodate multiple cavity tooling and is provided with means to sustain eccentric loadings from off center work. The machine is capable of stroking when the tooling and workpiece are absent without any dilatorius effects on the machine. The machine has completely adjustable tooling daylight from stroke-to-stroke.
摘要翻译：本文公开的机器被称为高速冲击成形机。它设置有两个工具或砧座构件和相关联的设备，其组装方式使得当使用机器时不会产生多次冲击或再起弧。该机器具有用于调节从行程到行程的能量输出的调节装置，从而使得使用者能够使用一系列变化的能量形成步骤，例如在热加工，预成形和阻挡中的断裂。提供了在成形之后立即将工具分离的装置，使得成形部件的处理可以立即开始而不间断地开始。因此，操作循环时间最有效。机器的结构使得基础荷载相对较低且完全可控。该机器可以具有足够的模具面积以容纳多个腔体模具，并且具有用于维持离心工作的偏心载荷的装置。当加工和工件不存在时，机器能够进行冲压，而对机器没有任何扩张效应。该机器具有从行程到行程的完全可调整的工具日光。

摘要： The proposed machine has a receiver accommodating a central piston connected to one of the holders and at least two lateral pistons carrying the second holder. The spaces above all pistons are communicated and filled with liquid. The holders are returned to their initial position by means of a crank mechanism whose connecting rod is coupled to the piston.

摘要： In a power hammer wherein work located on an anvil is acted upon by a ram located over the anvil an upper piston-and-cylinder means coacts with the ram to lower the latter along a driving stroke by way of a gaseous fluid under pressure and to raise the ram back to its starting position along its return stroke by way of a hydraulic fluid under pressure. A frame means which carries the anvil also carries part of this upper piston-and-cylinder means, while another part thereof is operatively connected with the ram. Beneath the frame means the foundation carries part of a lower piston-and-cylinder means which is operatively connected with the frame means for raising and lowering the latter. A conduit provides communication between the hydraulic fluid of the upper piston-and-cylinder means and the lower piston-and-cylinder means. A control valve is provided in the conduit to open the latter so that when the gas drives the ram downwardly the hydraulic fluid under pressure will flow through the conduit from the upper piston-and-cylinder means into the lower piston-andcylinder means to raise the frame means, and the anvil therewith, simultaneously with the downward movement of the ram.
