摘要： A press comprises a plunger mounted for reciprocations, one die rigidly fixed to the frame and the other die secured to a slide mounted for reciprocations in the frame guides for closing and opening the dies. The press is provided with a mechanism for clamping the dies during stamping which comprises a nut-screw kinematic couple. One member of the couple is rigidly connected to the slide and the other member, which performs the rotary motion, supports two adjoining discs, one disc being rigidly connected to said member and the other disc being connected to said member by means of a self-locking thread for helical movement relative to the first disc under the action of inertia forces for clamping the dies during stamping, and there is provided a drive for returning the second disc to the initial position.The disclosed press, according to the invention, has an improved efficiency with reduced power consumption as compared to prior art presses.

摘要： A screw press wherein slides carrying stamping tools are arranged on the frame coaxially with one another for reciprocation in opposite directions and connected to nuts cooperating with motion screws mounted on the frame, provided with flywheels and having right-hand and left-hand threads. A stamping die is arranged on the frame between the slides in such a manner that the splitting plane thereof is aligned with the stamping axis, one die is fixed to the frame and the other die is secured to a slide which is mounted in guides extending in the frame perpendicularly to the stamping axis, and there is provided a mechanism for clamping the dies during stamping. The motion screws are mounted in the frame for axial reciprocation during stamping. The press according to the invention is preferably used for stamping blanks of parts having asymmetrical distribution of metal mass lengthwise of the blank, such as turbine blades, compressor vanes and the like.

摘要： Hydraulic overload protection device for a press comprises a housing receiving therein a piston defining with this housing a space communicating via a check valve with a supply source and via a relief valve with a drain. This space additionally communicates with the drain via a line including an adjustable relief valve and a device for disconnecting the said space from the drain, when the movable member of the press, carrying a die, has been driven through the maximum length of its stroke. The disclosed protection device offers fine adjustment of the pressing or stamping effort and prolongs the service life of dies.
