The invention discloses a two-section-type bucket body and a manufacturing method thereof and belongs to the technical field of container manufacturing methods. The two-section-type bucket body comprises an upper conical body and a lower conical body which are coaxially arranged. The bottom of the upper conical body and the top of the lower conical body are subjected to welding forming to form a containing cavity. The upper conical body is subjected to integral punching forming, and the lower conical body is formed by embracing and welding of a plurality of lower conical body pieces. The forming mode of the upper conical body is changed into punching forming by adopting a mold from previous bending forming, after the mode is changed, no weld joint exists in the bucket body, the inner and outer surfaces are smooth, transition of the circular corners and circular arc faces are smooth and natural, and the situation that all dimensions accord with the drawing requirement is effectively ensured.
