摘要： The disclosed hammer comprises a power frame, having a working chamber for the deforming medium, a die block adapted to accommodate therein a blank and an impact head with a housing having fastened therein a hollow separating bush coaxial with the housing. Received concentrically within this bush is a sleeve enclosing a plunger mounted in this sleeve for vertical reciprocation, to define a working cylinder between the top end face of the plunger and the bottom of the sleeve. An annular space is defined by the housing of the impact head and the body of the separating bush, surrounding the working cylinder and communicating with the hydraulic hammer control system. The essence of the invention consists in that the working chamber for the deforming medium, has a built-in container having a bottom made of an elastic material. The container is mounted for cooperation of its bottom with the blank accommodated in the die block. In its turn, the die block is mounted for horizontal reciprocation, so that the blank can be placed thereupon outside the working chamber, whereafter the die block can be fed together with the blank to underlie the bottom of the container; the die block being also adjustable in a vertical plane to ensure a sealing engagement with the bottom of the container. The advantage of the present invention consists in higher efficiency of the disclosed hammer, as compared with the hitherto known hammers of a similar type.
摘要翻译：所公开的锤包括具有用于变形介质的工作室的动力框架，适于在其中容纳坯件的模具块和具有紧固在其中的具有与壳体同轴的中空分离衬套的壳体的冲击头。在该衬套内同心接收的套筒包围安装在该套筒中用于垂直往复运动的柱塞，以在柱塞的顶端面和套筒的底部之间限定工作缸。环形空间由撞击头的壳体和分离衬套的主体限定，围绕工作缸并与液压锤控制系统连通。本发明的精髓在于，用于变形介质的工作室具有内置容器，该容器具有由弹性材料制成的底部。该容器被安装成用于与其底部配合的容纳在模具块中的坯料。反过来，模块被安装成水平往复运动，使得坯料可以放置在工作室外面，之后模块可以与坯料一起供给到容器底部的下面; 模块也可以在垂直平面中调节以确保与容器的底部的密封接合。与迄今为止已知的相似类型的锤相比，本发明的优点在于所公开的锤的效率更高。
