摘要:
Expansion head for expansion tools for hollow workpieces, particularly for the ends of plastic pipes and metal-plastic composite pipes, comprising a union cap with a radially inwardly oriented guide flange, and a set of sector-shaped expandable jaws, each of which is individually received in the union cap in a radially movable manner by an inner flange sector that overlaps with the guide flange, the set of sector-shaped expandable jaws being movable between a closed state and an expansion state, and an approximately cylindrical lateral surface being embodied in the closed state by the outer wall of the expandable jaws, wherein the outer wall has at least one recess and/or raised area extending in the direction of the longitudinal axis of the expandable jaws.
摘要:
A tool device for connecting a plastic pipe or composite metal/plastic pipe to a fitting using 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.
