Abstract
A compression tool for joining tubular workpieces is provided with two or more arcuate compression jaws displaceable relative to each other in such a manner that the jaws can be opened for placement o a tubular segment of the workpiece. The compression tool (121) comprises compression jaw supports (132, 133) pivotally mounted on pivot bolts (134, 135). Two compression jaws (142-145) of each jaw support are guided along guide surfaces (138-141) which subtend an angle symmetrical to the center of the compression space when the compression jaws are in a closed state. The compression jaws are biased by a spring (146-149) along the guide surfaces (138-141) toward terminal end stops (150-153). Movement of the jaw supports about the pivot bolts (126, 127) permits opening and closing of the compression jaws.
