Embodiment Construction

[0022] A special machine for thin-wall girth welding of a stainless steel kettle according to the present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0023] A special machine for stainless steel kettle thin-wall girth welding, as attached figure 1 and figure 2 As shown, it mainly includes frame A, full circle mechanism B, pressing mechanism C and welding torch mechanism D. The frame A is provided with a lower frame surface A1 and an upper frame surface A2 respectively at different heights in the vertical direction, and a first The round hole a1 and the second round hole a2. The full circle mechanism B is fixed on the first round hole a1 of the lower frame surface A1, the pressing mechanism C is fixed on the second round hole a2 of the upper frame surface A2; the welding torch mechanism D is fixed on the on rack post A3 of the rack described above.

Abstract

The invention discloses a special annular welding machine for the thin wall of a stainless steel kettle, which is characterized by comprising a stand, a round mechanism, an ejection mechanism and a welding gun mechanism, wherein a lower stand surface and an upper stand surface in different heights are arranged on the stand in a perpendicular direction, respectively; the same center axis of the lower stand surface and the upper stand surface is provided with a first round hole and a second round hole, respectively; the round mechanism is fixed in the first round hole of the lower stand surface; the ejection mechanism is fixed above the second round hole of the upper stand surface; and the welding gun mechanism is fixed on a stand strut of the stand. The special annular welding machine has the advantages that the out-of-round problem of a circular weld surface of a drawing workpiece is solved, the upper and the lower parts of the workpiece are in butt welding; meanwhile, the secondary out-of-round problem generated by stress release due to high temperature in a welding process is solved. The welding position is protected by internal protection gases in the whole process, therefore, the welding defect caused by oxidization of stainless steel in the welding process is overcome.

Description

technical field [0001] The invention relates to a welding machine, in particular to a special machine for thin-walled ring welding of a stainless steel kettle with internal protective gas protection. Background technique [0002] At present, in the production process of stainless steel kettles, the connection between the upper part and the lower part of the kettle body is divided into two ways: undercut and welding. The former undercut has limitations, it is only suitable for connection at the corner, and it is not suitable for the connection of the kettle body divided into two parts from the waist, thus limiting the development of the kettle; at the same time, there is a gap at the undercut of the undercut kettle, which is a hygienic corner in use , not easy to clean. The welding operation of the latter is extremely difficult: first, the material of the pot body (0.5mm-0.8mm) is relatively thin, which belongs to thin-walled butt welding; secondly, when welding stainless st...
