Mounting attachment, use and method of manufacture

Abstract

A mounting attachment with a connection area for a gas line includes a first cylindrical fastening medium and a second cylindrical fastening medium, which are in particular screwable into each other. The first fastening medium and/or the second fastening medium are prepared in a 3D-plastic printing process. A pipe to be welded is inserted into the first cylindrical fastening medium by means of an essentially central lead trough in the first cylindrical fastening medium, with a cylindrical area of insertion for the pipe to be welded in the second fastening medium. The area of application includes an attachment ring area and a connection area for a gas feed hole for feeding forming gas to a gas-use point by means of a forming gas pipe in the pipe to be welded. The pipe used is sealed against the cylindrical fastening media by one or more flexible seals.

15. The mounting attachment (1) according to claim 11, wherein into the second fastening medium (5) at the gas feed hole (10) for feeding forming gas into the pipe (7) a forming gas nozzle (18) is placed extending the forming gas line (3), which causes a vortex-shaped diversion of the incoming forming gas.

16. The mounting attachment (1) according to claim 11, wherein a circumference of a cylinder width of an insert end (20) of the first fastener (4) is equal to a standardized pipe thickness (21) and/or the forming gas line (3) being standardized to the second fastening medium (5) being screwed to a 3D printed thread (22).

17. The mounting attachment (1) according to claim 11, wherein the first fastening medium (4) and the second fastening medium (5) are formed in one piece together with the one or more flexible seals.

18. The mounting attachment (1) according to claim 11, wherein the first fastening medium (4) and/or a second fastening medium (5) are adapted to an FDM printing process.

19. A method, comprising: providing the mounting attachment (1) according to claim 11; mounting the pipe (7) with the forming gas line (3) as a protective gas line in hot-processing of metals, namely soldering and/or welding and/or rolling and/or pressing and/or annealing, TIG manual and TIG orbital welding, wherein the first fastening medium (4) and the second fastening medium (5) and/or the one or more flexible seals are formed in a 3D printing process that can be adapted to the pipe.

20. A method for manufacturing a mounting attachment (1), comprising: attaching a mounting attachment (1) with a connection area (2) for a forming gas line (3) to a pipe and attaching a first cylindrical fastening medium (4) and a second fastening medium (5) to each other in a removable way, wherein the first cylindrical fastening medium (4) and the second fastening medium (5) are fitted in a 3D plastic printing process in such a way that the pipe (7) to be welded is held with a cylindrical area of insertion (8) by an essentially centralized lead trough (6) in the first fastening medium (4). for the pipe to be welded (7) in the second fastening medium (5), wherein the area of insertion (8) has an attachment ring area (9) and a connection area (2) for a gas through hole (10) for feeding forming gas to a gas use point through a forming gas pipe (3) in the pipe (7) to be welded, wherein the pipe (7) is sealed to the first fastening medium (4) and the second fastening medium (5) by seals (12), which are manufactured custom-made in a 3D plastic printing process and which, after assembly, keep the pipe sealed.

DETAILED DESCRIPTION

[0020] FIG. 1 shows a device according to the invention in perspective, where a mounting attachment 1 with a connection area 2 for forming gas line 3 is arranged to a pipe 7, comprising a first cylindrical fastening medium 4 and a second cylindrical fastening medium 5, which can be attached to each other are inter alia screwable with each other, the first fastener 4 and/or a second fastening medium 5 being so adapted in a 3D plastic printing process that a pipe 7 to be welded and inserted with a cylindrical application area 8 is to be held by means of an essentially centralized application 6 in the first fastening medium 4 for pipe 7 to be welded in the second fastening medium 5, where the area of application 8 has a connecting ring area 9 and a connection area 2 for a gas through hole 10 for feeding forming gas to a gas use point through a forming gas line 3 in the pipe to be welded 7, where the pipe used 7 is compared to the z Cylindrical fastening media 4,5 are sealed by one or more seals 12, in particular sealing rings 13, which are custom-made in a 3D plastic printing process, whereby seals 12, in particular a first seal 14 and a second seal 15, are used in the first 4 and/or second cylindrical fastening media 5.

[0021] Seals 12, e. g. elastic hollow rings 16, are separated by several intermediate elements 17, so that a functional unit is formed which can be used in the second fastening medium 5, whereby, when fastening, in particular screwing the fastening media 4,5 to each other, the seals, in particular hollow rings 16, against the intermediate element(s) 17 and against the rotating device used piping are to be pressed sealing.

[0022] FIG. 2 shows a device according to the invention in an external view. In particular, it demonstrates how easy and safe the connection of the mounting attachment 1 is possible, whereby an unrepresented pipe is held by a sealing function unit.
