摘要： A machine for producing a body with desired shape of a workable material through dynamic forging under impact and finally with energy retention while the shock wave fades out. The machine includes a machine stand, a dynamic outer impact system having an upper unit, and a lower impact unit, which includes a counter-impact device, and possibly one or more dynamic side impact units, and a static inner press system having an upper unit and a lower unit, possibly with additional one or more static side compacting units, with a central unit in between. The lower units of the outer and inner systems can be exchanged with a common stationary anvil for a single direction machine instead of a counter-acting machine.

摘要： The invention relates to a press driven work tool module comprising a power unit and a work unit. Each unit comprises a fluid filled cylinder, a piston for reciprocation therein, and a piston rod. Hydraulic fluid within the power stroke displacement space of the power cylinder is in communication with hydraulic fluid in the work displacement space of the work cylinder, and hydraulic fluid within the return displacement space of the power cylinder is in communication with hydraulic fluid within the return stroke displacement space of the work cylinder. The power cylinder is provided with a moving top plate connected to the power piston rod and a spring arrangement for urging the top plate and power piston rod to the return position, such that a drive force acting on the power piston rod moves the power piston and work piston to the power and work ends of the respective cylinders against the spring bias. The system is hydraulic and eliminates the need for pressurized gas, avoiding problems such as contamination, worn seals, loss of pressure over time, and need for recharging.

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： A counterstroke hammer in which two rams are moving towards one another until they come into contact along guides scured to a frame. The rams are accelerated by a drive provided with a plunger and a cylinder moving with respect to the frame and both rams in the direction of their movement. The drive cylinder is connected to one of the rams through tie-rods to effect simultaneous interaction when an acceleration force is imparted. The cylinder and its ram is then disconnected from the system in order to ensure the ram movement free from the action of the drive. The drive plunger is adapted to contact the other ram during the transmission of the acceleration force and is disconnected from said contact after the acceleration, for effecting the ram movement free from the drive action. The impact interaction of the rams takes place with the drive disconnected and hence the kinetic energy thus obtained is damped, while the kinetic energy of the cylinder and plunger is damped independently of the rams.
摘要翻译：一个反冲击锤，其中两个公柱相互移动，直到它们沿着引导件接触到一个框架。柱塞通过设置有柱塞和相对于框架移动的缸的驱动器被加速，并且两个柱塞在其运动方向上移动。驱动气缸通过拉杆连接到其中一个柱塞上，以在施加加速力时实现同时的相互作用。然后将气缸及其压头与系统断开连接，以确保压头运动不受驱动器的作用。驱动柱塞适于在传动加速力期间接触另一柱塞，并且在加速之后与所述接触件断开连接，以使冲头运动免于驱动动作。柱塞的冲击相互作用发生在驱动器断开的情况下，因此获得的动能被阻尼，而气缸和柱塞的动能独立于压头而被阻尼。

摘要： A method for hot forming of a cast forging ingot uses a forging device with radially guided forging dies of which each have two die parts, which can be radially moved relative to each other and of which the inner die part bearing a forging tool is drive-connected, using a hydraulic cylinder, to the other, outer die part, which can be driven using an eccentric drive. In order to provide advantageous forging conditions, the forging ingot is formed under heat, first using the forging dies driven by the eccentric drive, in near-surface forge processing with a degree of deformation which is above the critical degree of deformation and which excludes the formation of cracks, and then, with the outer die parts stopped, with the aid of the inner die parts driven by the hydraulic cylinders, in forge pressing with a bite ratio of >0.5.

摘要： The present invention relates to a method for material working utilizing high kinetic energy, in which a stamp or striking body transfers, by delivering a blow, high kinetic energy to a material body that is to be worked, after which a rebound of the stamp occurs. In an embodiment of the method, a measure is taken in conjunction with said blow delivered, which measure prevents said stamp from delivering an afterblow with an appreciable kinetic energy content, for the purpose of avoiding negative effects as a consequence of afterblows.
