5. The sheet metal part forming process of claim 4, wherein the step of splicing further comprises:
And performing laser welding on the first arc-shaped joint (410) to connect the second bending plate (322) with the arc surface (400) to be spliced.
6. The sheet metal part forming process of claim 4, wherein the step of splicing further comprises:
and applying acting force to the first bending plate (321) to enable the first bending plate (321) to bend relative to the fixing plate (310) along the straight line where the first straight line segment (120) is located, so that the cambered surface (400) to be spliced is abutted to the fixing plate (310) to form a second arc-shaped seam (420).
7. the sheet metal part forming process of claim 6, wherein the step of splicing further comprises:
and performing laser welding on the second arc-shaped joint (420) to connect the arc surface (400) to be spliced with the fixing plate (310).
8. The sheet-metal part forming process according to claim 2, wherein the length of the first straight line segment (120) increases with the increase of the radius of the arc surface (400) to be spliced; the ratio of the length of the first straight line segment (120) to the radius of the corresponding cambered surface to be spliced (400) is gradually reduced along with the increase of the length of the first straight line segment (120).
9. the sheet-metal part forming process according to claim 3, wherein the length of the second straight line section (220) increases with the increase of the radius of the arc surface (400) to be spliced; the ratio of the length of the second straight line section (220) to the radius of the corresponding cambered surface to be spliced (400) is gradually reduced along with the increase of the length of the second straight line section (220).
10. An integrated cooker, characterized by comprising a top cover plate (500), the top cover plate (500) being manufactured by a sheet metal part forming process according to any one of claims 1-9.
