This invention relates to the field of tank processing technology, and discloses a tank bottom assembly, a tank, and a method for forming the tank bottom assembly. The tank bottom assembly includes a tank bottom and a transition ring. The transition ring is located at the open end of the tank bottom and is integrally formed with the tank bottom. The outer wall of the transition ring has a first step surface and a second step surface that are vertically arranged. The first step surface is arranged radially along the transition ring, and the outer edge of the second step surface away from the first step surface is inclined towards the outer wall of the tank bottom to form a guide slope. The tank includes a cylindrical section and the aforementioned tank bottom assembly. The method for forming the tank bottom assembly includes the following steps: fixing the outer ring of a constraint plate, and shearing and spinning the plate using a spinning wheel to obtain a first formed part; releasing the outer ring constraint and fixing the inner ring constraint, and flanging and spinning the outer ring using a spinning wheel to form a column section; machining a mating interface on the outer wall of the column section to obtain an integrally formed tank bottom and transition ring. The tank has better quality and lower processing costs.
