Description

A hydraulic stamping press of a 1n column type press with a cross bar and a frame assembled from sheets is known for the production of large-sized parts of complex configuration, equipped with a synchronizing sync device for automatically leveling the mobile sliding bar under the action of an eccentric applied load.

In the press described mTajMnoBO4noM hydraulic press apologichnon designs are applied soir guards with wedge beams in wedges and rubber shock absorbers.

Such a structure ensures the transfer of the leveling moment to all the sheets constituting the traverse and the frame.

FIG. 1 shows a hydraulic punch press; in fig. 2 traverse movement; pas figs. 3 is a diagram of the alignment of the imbalances of the mobile beam; in fig. 4-beam key with wedge mi.

In order to obtain high precision forgings and to protect the colony from bending and cleavage, an automatically acting synchronizing system for aligning the mobile traverse was used.

This system consists of four selsins / piston-type “rotary spool mounted installations. When the movable yoke 2 is misaligned, the rotation of the selsyn is misaligned, which gives an imulse to the switching of the corresponding spool connecting the pump to the bottom of the cylinder of the equalizing cylinders 3, creating a moment that counteracts the moment arising from the eccentric applied force and prevents the mobile yoke 2 from inclining the output beyond the predetermined value. If, for any reason, the traverse tilt exceeds the specified limits, the action of the press force is automatically terminated by relieving pressure from its working cylinders.

For the transfer to all sheets constituting the traverse and the frame, the leveling moment created by the synchronizing rsilin system, spline beams 4 are used, which are matched with the sheets of the bed 5 of the bed and the base beam with the help of wedges 6. In the nodes of the guide bronze bushings 7 are movable traverse 2 uses rubber dampers 8 for unloading columns 9 from stresses arising from distortions traverse 2 within the limits allowed by the synchronization system.
