FIELD OF THE INVENTION The invention relates to the field of riveting and assembly operations, in particular, to a manual press, used for dismantling bolt-rivet joints.

The aim of the invention is to expand the technological capabilities and increase productivity by allowing regulation, lining / press by changing the distance between its consoles, which allows for disassembly of bolt-riveted joints of various sizes,

The drawing shows a manual press, the general view,

The hand press contains a drive 1 with a C-shaped detachable bracket mounted on it, having a console 2 with an anvil 3 fixed on it, connected to the housing of the drive 1 and fixed on it by a fastening element 4, in a cylindrical cavity 5 salt 2, is mounted with the possibility of reciprocating movement of the console 6, connected with the movable element 7 of the drive 1. On the console 6 by means of pins 8 mounted knife 9, at the end of the movable element 7 of the actuator 1 there is a ring 10 threaded on the inner surface and cylindrical side surface.

Manual press works as follows.

The press is guided to the bolt-rivet ring to be removed so that the ring is in the stop-position 3 of the console 2. When the trigger is pulled, the displacement occurs 10

the moving element 7 of the actuator 1 and, respectively, associated with the element 7 of the console 6 and the support ring 10. The ring-bolt-5 ring is pressed and centered in the cradle 3 of the console 2 and with further movement of the console 6 is cut by a knife 9. The cantilevers 6 are transmitted as a bending moment through the support ring 10 and the movable element 7 to the console 2. In this case, the support ring 10 experiences high specific pressures, but since it is made of an antifriction material, this reduces friction in the pair: The aqueous cavity 5 of the console 2 and the support ring 10.

To ensure that the bolt rivets are dismantled in another size, the press is re-adjusted. Press adjustments are made as follows. Turning the fastener

25 of the element 4, the console 2 is rotated relative to the housing of the drive 1, the rotation of the consoles 2 in one direction or another, the console 6 is moved relative to

30 of the movable element 7, since they are interconnected by threads. This achieves a change in the gap between the brackets in the position corresponding to the disassembly of the bolt-rivet. In the desired position, the console 2 is fixed relative to the housing of the actuator 1. The manual press improves the productivity of labor during repair work when it is necessary to dismantle the bolt-rivets of various diameters,
