PATENT OFFICE.

This steam-hydraulic press is arranged in such a way that the work to be performed by it can be adapted to the conditions of the workpiece and the press both for Forging of heavy and light work pieces, to mate and bend deeper like flat body, for temporary pressing and also for high-speed forging, in general for all Blacksmithing and prefabrication can be used with advantage.

This is achieved by the fact that the steam hydraulic press is equipped with several steam propellants and several prefabricated cylinders are provided, which can be connected in such a way that either all propellants work in all prefabricated cylinders or that only one or more of them work on all Pref-cylinders act, or finally all or one or more of the steam-driving apparatus work with one or more of the prefs cylinders.

From this it can be seen that the force generated by the steam propellant can be used both in terms of their strengths as well as their path in the most varied of ways and within wide limits can have an effect on the work piece.

In the drawing, such a steam hydraulic press is, for example, with three Steam propellants and three prefabricated cylinders shown; it shows:

Fig. Ι the front view of the press with a section through the prefs and lifting cylinders,

Fig. 2 is the front view of the steam propellant,

Fig. 3 is a side view of a steam propellant.

The press, which is supplied with pressurized water by the propellants, has the press frame d above the press cross member c , which is equipped with several (in the present case three) prefs cylinders α α _Ύ a. _{2 is} equipped. The pistons attached to the pressure traverse c guided on the columns e fit into this. Between the three prefs cylinders, two lifting cylinders b are arranged, in which the lifting pistons, which are also connected to the pressure cross-member c , work in a known manner.

The prefabricated cylinders α α _γ a ₂ receive the pressurized water (if necessary, another suitable liquid) from the three steam propellants AA ₁ A ₂ , whose pressurized water cylinders are connected to the prefabricated cylinders and among each other by pipes in such a way that all or one or more of the propellants are connected all or one or more of the Prefscylinder can be connected. The pressurized water cylinders are in communication with each other through the pipes s.

A tube t connects the pressurized water cylinder of the steam drive apparatus A ₂ with the central pref cylinder a _x . The pressurized water cylinder of the steam drive apparatus A is connected to the prefs cylinder α by means of the pipe u. The pressurized water cylinder of the steam drive apparatus A _{1 is} connected to the prefs cylinder a ₂ by a pipe U ₁ . Both the pipe t and the pipe u and U _{1 have} a barrier w. W _{1 and} W 1 respectively. w _v With the help of these pipe connections one can

As you can see, the available power can be in nine different ways to be implemented in work. One can apply all or part of the force to all or let one or two of the prefs cylinders work. Is z.

work.

You can also exert pressure on one side against a workpiece in order to z. B. to give the same on one side using a corresponding prefix a special shape. In this case, one of the taps w W ₁ W _{2 is} closed as required. The great versatility of the application of the steam hydraulic press with several steam propellants and several presses is immediately apparent.

The controls of the propulsion apparatus are arranged independently of one another and, moreover, can be set up in any suitable manner. The lifting of the piston with the pressure traverse is done by means of any of the devices known from hydraulic presses. In the example shown, two hydraulic lifting cylinders bb _x are arranged for this purpose. The filling and refilling of the hydraulic working cylinder and the prefabricated cylinder is carried out in the usual way with steam hydraulic presses. Connecting pipes op are arranged to compensate for the fillings and the pressures in the working cylinders and prefs cylinders.

Claims (1)

Patent claim: A steam forging and dishing press, characterized in that the pressure traverse c is provided with several Prefscylindern a Ci ₁ a ₂ , which are connected to several steam driving devices in such a way that by suitable opening and closing of the connecting paths (taps w W ₁ W ₂ ) and One resp. Disconnection of the propellants (AA ₁ A ₂ ) either all propellants work in all prefabricated cylinders, or only a part of them acts on all prefabricated cylinders, or finally that all or a part of the steam propellants work with a part of the prefabricated cylinders, for the purpose, the strength and the To be able to regulate the way of the force acting on the prefs cylinder depending on the type and size of the workpiece. 1 sheet of drawings.
