ABSTRACT:
A flash butt welding facility exhibits a housing (1) and a slide (2) linearly displaceable in the former. Respectively one clamping system is installed in the housing (1) and in the slide (2), by means of which profiled workpieces, e.g. rails (5a, 5b), can be retained and positioned. A device for displacing the clamping systems, especially for compressing profiled workpieces (e.g. rails), comprises at least one press cylinder (11) arranged above the workpiece clamping axis (17) and acting in the longitudinal direction and at least one lever (8) rotatably connected to the slide (2) in the force application point (9). The press cylinder (11) is connected to one end of the lever (8). The center of the lever (8) is articulated (7a) to the housing by way of a pull rod (6a). The pressing force produced above the rail clamping axis (17) is made to be effective in the clamping axis in this way.
