TOOL DEVICE FOR THE CONNECTION OF A PLASTIC PIPE OR OF A COMPOSITE METAL/PLASTIC PIPE TO A FITTING BY WAY OF A SLIDING SLEEVE OR COMPRESSION SLEEVE

摘要

A tool device for connecting a plastic pipe or composite metal/plastic pipe to a fitting by means of a sliding sleeve or compression sleeve. The device includes a housing; a flaring device for flaring the ends of the plastic pipe or composite metal/plastic, pipe; a sliding device for sliding the sliding sleeve on or a pressing device for pressing the compression sleeve, on; and a mechanically operable drive element. The drive element can be switched to drive the flaring device or to drive the sliding device or pressing device. The flaring device includes a first piston-cylinder unit, whose working piston has a piston axis and which has an inner end and an end oriented away from the tool device. The sliding device or pressing device includes a second piston-cylinder unit, whose working piston has a second piston axis and which has an inner end and an end oriented away from the tool device. The piston axes extend parallel to each other and a perpendicular projection of the inner end of the flaring device onto the piston axis of the sliding device or pressing device lies between the inner end of the sliding device or pressing device. The end oriented away from the tool device and/or a perpendicular projection of the inner end of the sliding device or pressing device onto the piston axis of the flaring device lies between the inner end of the flaring device and the end oriented away from the tool device.
