Detailed Description

The utility model will now be described in further detail with reference to the drawings and examples. Wherein like parts are designated by like reference numerals. It should be noted that the words "front", "back", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

Referring to fig. 1 to 3, a stamping type pipe fitting assembly of an S-shaped cooking pipe of the present embodiment includes two stamping core wires 1 and a corrugated pipe 2 which are disposed opposite to each other, and the stamping core wires 1 at both ends have a certain adjusting space and can be bent by the arrangement of the corrugated pipe 2;

the two ends of the corrugated pipe 2 are respectively welded with the stamping core wires 1, the stamping core wires 1 and the corrugated pipe 2 are externally provided with the buckling lantern rings 3, the buckling lantern rings 3 limit the moving range of the nuts 4 on one hand, the spacing distance between the buckling lantern rings 3 and the stamping protrusions 11 is limited, so that the moving range of the nuts 4 is limited, and the welding position between the corrugated pipe 2 and the stamping core wires 1 is protected on the other hand;

the stamping welding core 1 is stamped to form an annular stamping bulge 11, and the stamping bulge 11 is formed by stamping, so that the movable connection of the nut 4 is realized, the stamping welding core 1 is easy to process, and the forming size is stable;

the punching core wire 1 is movably connected with a nut 4, and the nut 4 is limited between a corresponding punching protrusion 11 and the buckling collar 3, wherein the pipe thread in the nut 4 is G1/2.

The stamping core wire 1 is made of a thin-wall stainless steel welded pipe, wherein the thin-wall stainless steel welded pipe is easier to stamp and weld, and compared with the existing method for processing by adopting blanking and cold heading of a seamless pipe, the method saves cost, reduces the difficulty of a production process and improves the production efficiency.
