SU827317A1 - Device for mounting and dismantling press-units in a press - Google Patents

Description

RO.V 2 is carried out from the manual hydraulic pump 12 through the pipeline 13, the valves 14 and / 5. When installing the pressing unit in the working area of the press, the latter is connected with the upper 16 and lower P-Blades of the press with its claws.

The device works as follows.

Before transporting the pressing unit to the working area of the press, the valve / i5 is closed from the guide brackets 9; And the valve 14 in the pipeline opens. By means of a hand pump 12, a working fluid is pumped through the pipeline 13 into the cavities of the tank C until the guides 4 are raised from the level; on the other hand, the projection iB of the guide brackets 9 (not shown in the drawing).

The magnitude of the stroke of the guides 4 lies within S 1 -1.5 mm. The alignment of the surfaces B and B of the guides 4 and of the guide brackets 9 allows the transport unit to be freely transported to the press-pressing area.

The press unit, together with the device, is installed by supporting rollers 5 on the brackets 9, then, with a light movement, rolls into the working area of the press up to a hard stop 10. After the pressing block is brought to its attachment points, the valve 15 is opened, and the liquid under the press block is forced into the tank. pump 13, and the nipecc block is lowered onto

The supporting surface of the table and fixed in the desired position.

When dismantling the press unit, the pr-unit will pre-release the bolts securing it

to the table, grove production of the press unit

plunger 2 to match. planes in

and B and roll it out on brackets 9.

The proposed device provides the ability to easily and quickly replace in the process of operation and bulky press blocks on presses, which, compared to the known, is smaller in size and metal consumption.
