摘要： Apparatus for the hydroplastic processing of tubular products which finishes the inner surfaces of such products while attaining exact outer dimensions thereof. The apparatus employs a vertical hydraulic press having a movable slide and a work table therebeneath. To the slide there is attached a device for the hydroplastic processing of tubular products, and on the workpiece of the press there is secured a positioning fixture bearing at least one die adapted to have a billet introduced thereinto. Secured to the slide of the press is a carrying plate and beneath the carrying plate and spaced therefrom there is a base plate upon which there are mounted a vertical broaching rod and, laterally spaced therefrom, a knockout rod. The positioning fixture is selectively movable to bring the die thereon into a first working position, in which it is aligned with the broaching rod, and selectively moving it into a second working position, in which the die with the now fully worked tubular product being disposed in alignment with the knock-out rod. On one side of the work table there is positioned a billet loading unit, and on the other side of the work table there is disposed a handling manipulator for transporting work tools to be secured to the lower end of the broaching rod. Means are provided beneath the work table for the carrying away of finished tubular products which are pushed from the die in the second work position thereof by the knockout rod.

摘要： Method of and apparatus for forming blanks by hydroplastic deformation. In a closed deformation space there is supplied a working fluid under high pressure and, simultaneously, the material of the blank to be deformed which is disposed in the deformation space is subjected to plastic deformation by the working fluid. In the zone of the closed deformation space there is applied a concentrated and controllable impulsed fluid load, this load being applied cyclically at equal time intervals and being controlled along the length of the blank being deformed.The apparatus of the invention comprises a working tool with a blind central hole and radial channels connected thereto, and a female die in which the blank to be deformed is disposed. The working tool is connected to a supply cylinder in which there is provided a pressure chamber, the pressure chamber containing a piston connected to the working tool. The supply cylinder is fastened to the movable part of a press. The pressure chamber is connected to an impulse activator by means of a plunger which is attached tightly to the supply cylinder.
