Abstract
A forming tool for pipe ends with a fixing device holding the pipe and a flanging die acting on the projection of the pipe end, where the flanging die has a mandrel which can be driven into the pipe end. A forming die surrounds the mandrel. The mandrel and the forming die are held in a housing. A limiting die surrounding the forming die being provided.
Claims14
Forming tool for pipe ends (50) with a fixing device (54) holding the pipe (52) and a flanging die (12) acting on the projection of the pipe end (50), wherein the flanging die (12) has a mandrel (48) which can be driven into the pipe end (50) and a forming die (40) surrounding the mandrel (48) and the mandrel (48) and the forming die (40) are held in a housing (10), characterised in that a limiting die (24) surrounding the forming die (40) is provided.
Forming tool according to either of the preceding claims, characterised in that the limiting die (24) projects beyond the housing (10) axially in the direction of the pipe end (50).
Forming tool according to any of the preceding claims, characterised in that the limiting die (24) is resiliently mounted in the axial direction via a spring (30).
Forming tool according to any of the preceding claims, characterised in that the limiting die (24) has a sleeve-like shape.
Forming tool according to any of the preceding claims, characterised in that the limiting die (24) is guided in an axial aperture of the housing (10).
Forming tool according to any of the preceding claims, characterised in that the forming die (40) is guided axially displaceably in the limiting die (24).
Forming tool according to any of the preceding claims, characterised in that the forming die (40) is mounted axially displaceably on the mandrel (48).
Forming tool according to any of the preceding claims, characterised in that the forming die (40) can be driven axially into the housing (10) counter to the pressure of a spring (46).
Forming tool according to any of the preceding claims, characterised in that the housing (10) has a three-stage aperture (14) and all components can be inserted into the housing (10) from the end remote from the pipe end (50).
Forming tool according to any of the preceding claims, characterised in that the end of the housing (10) remote from the pipe end (40) has a screw cap (22).
Forming tool according to any of the preceding claims, characterised in that the pressure force of the forming die (40) can be adjusted via the end of the housing (10) remote from the pipe end (50).
