Plug part and socket part for detachably connecting a pipe elbow of a water-cooled welding torch and connecting device
Abstract:
The invention relates to a plug part (21) for detachable connecting a torch neck (19) of a water-cooled welding torch (7) to a socket part (34) arranged on a hose package (20), having a cylindrical pipe element (22) with an axially running channel (23) for a welding wire (9) and a protective gas (5) and having at least two cooling channels (29, 30) for supplying and returning a cooling fluid, and a union nut (24) rotatably arranged on the pipe element (22), the union nut having an internal thread for connection to a mating external thread on the socket part (34), the invention further relating to such a socket part (34). In order to produce an optimal connection between the torch neck (19) and the hose package (20), a flange (25) having at least one receiving opening for receiving a pin-like element (36) of the socket part (34) is arranged on the pipe element (22) of the plug part (21) in order to fix at least one angular position of the torch neck (19).
Abstract(Chinese):

本发明涉及一种用于将水冷焊枪（7）的火炬颈（19）可拆卸地连接到布置在软管包装（20）上的插座部分（34）上的插头部分（21），其具有圆柱形管件 （22），其具有用于焊丝（9）的轴向运行通道（23）和保护气体（5），并且具有用于供应和返回冷却流体的至少两个冷却通道（29,30），以及联管螺母 24），可旋转地布置在管元件（22）上，联接螺母具有用于连接到插座部分（34）上的配合外螺纹的内螺纹，本发明还涉及这种插座部件（34）。 为了在割炬颈部（19）和软管包装（20）之间产生最佳的连接，具有至少一个用于容纳插座部分（34）的销状元件（36）的接收开口的凸缘（25） 布置在插头部分（21）的管道元件（22）上，以便固定手电筒颈部（19）的至少一个角位置。
