FIELD: mechanical engineering.

SUBSTANCE: invention relates to equipment for connecting sheet parts by bulging. The machine comprises a tool holder in the form of a fixed frame and a movable rocker arm, provided with a punch and a matrix. A piston group is connected with the tool holder by means of a disk with an auxiliary handle, containing a piston connected with a wedge mechanism made with a lower rectilinear section interacting with a roller support. A control unit with elements of a pneumatic system and machine operation control units is secured in the end part of the piston group. Provided are a a unit for setting the axial alignment of the punch and the die and the depth of insertion thereof, in the form of an eccentric axis and an eccentric, the position whereof is locked by screws, and a safety valve for relieving excess pressure.
