    摘要： A method and device for perforating a pipe wall. In the method, the pipe is moved in its longitudinal direction to a punching position comprising a cutting punch (2) and a three-part die (3, 5, 8) inside the pipe. The die (3, 5, 8) is expanded in the direction of movement of the cutting punch by means of the wedge surfaces (8a, 8b) of a wedge (8) between the die parts (3, 5) by moving the wedge (8) in a first direction of transfer towards the free end of the die. The cutting punch (2) is used to punch a hole in the pipe wall, which is supported by an expanded die (3, 5, 8) during punching, whereupon the piece punched off from the pipe falls into the hole (16) of the upper die part (3), The die is contracted by moving the wedge (8) in a second direction of transfer by a first transfer distance. The die parts (3, 5) then turn in an articulated manner towards each other and out of contact with the inner surface of the pipe. The perforated pipe is moved away from the punching position in its longitudinal direction and the pipe is moved to a position for finishing the rims of the hole. The lower die part (5) and the wedge (8) are further moved together in a second direction of transfer by a second transfer distance, whereupon the base of the hole (16) opens and the piece punched off from the pipe falls through the hole (16).

    摘要： A two piece pulling member is used to form a branched opening with a shoulder in a side wall of a malleable pipe without requiring the pulling member to be inserted from an end of the pipe. The pulling member has a base and a top that are individually placed through the initial hole in the pipe. The base and the top are assembled into a unit inside the pipe.

    摘要： A tool forms a threaded hole in a hydroformed part while the part remains in a hydroforming die cavity and under pressure. The tool has a hole-piercing end portion adapted on advancement of the tool to pierce and form a hole in the part and an extruding portion adapted on continued tool advancement to extrude an annular extrusion that extends into the tube interior. An adjacent sealing portion of the tool seals the hole during the ongoing advancement and extrusion of the annular extrusion so that hydroforming fluid remains under pressure. A thread-forming portion of the tool forms an internal thread within the annular extrusion upon the continued advancement and rotation of the tool.
