<p>The press wrench tool (2), to connect a pipe section in a press fit, has a drive and a drive connection with two holding plates (22) to the wrench (1). The wrench (1) has two swing arms (12), between two T-shaped carrier plates (11) at two bearing mounting bolts (13) with a gap between them, through the swing arms (12), to give a swing mounting with the carrier plates. The swing arms (12) have clamping pads (14) with press surfaces. The swing arms (12) are operated so that their movement is fixed evenly and against each other. The movements of the swing arms are set by bearing bushes as carriers which act on them. The wrench (1) is fitted into the tool (2) at the laying surface (23) and, on further retraction, the swing arms (12) are moved outwards to the side to give the press action.</p> |
