A punching mold device capable of rotating a workpiece includes an upper mold base, a lower mold base opposite to the lower mold base, an indexing rotation plate, a servo motor and a position-fixing element. The lower mold base includes a clamping portion for fixedly clamping a workpiece. The indexing rotation plate is formed with holes which collectively form a circular contour. The servo motor is connected to the indexing rotation plate and the workpiece, and synchronously rotates the indexing rotation plate and the workpiece. The position-fixing element includes a positioning pin which aims towards and is pluggably connected to one of the holes for stopping the rotation of the indexing rotation plate and the workpiece. The upper mold base includes a punching head module aligned with the clamping portion for punching the workpiece.

A method for disposing of a slug produced in a hole punching operation on a hollow profile is provided. The method includes the steps of providing a hollow profile; cutting at least one predeterminable hole or slug contour path into the hollow profile by means of a cutting device; leaving a residual web of the hole or slug contour path; moving a receiving device into the hollow profile; moving a punch from a first position into a residual-web-removing second position in such a way that the slug thereby produced is received by the receiving device; and moving the receiving device out of the hollow profile.

A mating plug connector for connecting components for liquid or gaseous media includes a connector body with: an insertion section which serves for insertion into a receiving opening of a plug connector; and a component connection which serves for connection with one of the components. The connector body is configured as a formed sheet metal part.

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).
