Specific embodiment
In order that the technical solution of the utility model becomes apparent from, below in conjunction with accompanying drawing 1 to 4, this utility model is carried out
Describe in detail.It should be appreciated that the specific embodiment described in this specification is just for the sake of explaining this utility model, and
Be not configured to limit protection domain of the present utility model.
This utility model is a kind of seamless vacuum cup, including cup 1 and bowl cover 2, the cup include stainless steel casing and
Stainless steel inner container 12, is formed with the folding portion for bending laterally, the folding portion in the upper end of 12 oral area of the stainless steel inner container
121 outer sheath of lower flap located at stainless steel casing oral area upper end 111, the termination 112 of the upper end 111 with it is sagging
It is welded as a whole structure by argon arc welding between the bent angle 122 on side 121.
Preferably, the top of the termination 112 is concordant with the top 123 of folding portion, the stainless steel casing includes shell
Body 11, middle bottom 4 and cup bottom 3, with the inner side of 11 bottom of housing by laser welding, housing 11 is certainly for the lower end of 4 outer of said midsole
At laser welding, 5 extend downwardly composition housing extension portion 113, the lower end of the housing extension portion 113 and the upper end pair at cup bottom 3
Connect, be welded as a whole structure by argon arc welding in joint 6.Constituted by polishing in each argon arc welding weld smooth
Surface.
Processing method of the present utility model comprises the steps：
Flange step：The upper end of 12 oral area of the stainless steel inner container is bent laterally, folding portion is formed；
It is arranged step：Stainless steel inner container 12 is loaded into stainless steel casing, 121 outer sheath of lower flap of folding portion is made located at not
