The manipulator for machines of forging, for example to a multiple slides forging machines.

摘要

In a manipulator for machines of forging, for example for forging machines with multiple slides with several sliders which acts radially on the forging, the workpiece is displaced axially in accordance with the sequence of forging, and the entraînenent of travel of the manipulator is carried out at a constant speed. A drive superimposed, with axial action and activity controllable, are periodically on the shaft of the clamp (5) of the manipulator, and at least one cylinder - piston (12), working hydraulically, is arranged to support the shaft of the clamp to move axially (5) screw - to - screw of the casing of the manipulator. In order to obtain, by mechanical means that the control of the manipulator is functionally reliable and simple, the front chamber (18) and the rear chamber (19) of the cylinder - piston (12) can be connected by a pipe (28) by means of a valve (26), and the cylinder - piston (12) is designed as a servo-control system (17), making it possible to control the entire cylinder - piston (12).
