Process for producing special-shaped double-layer metal vacuum cup

Abstract

The invention relates to a process for producing a special-shaped double-layer metal vacuum cup. The process comprises the following steps that (1), a cup shell body, a cup shell opening part, a cup shell bottom and a cup liner are manufactured respectively; (2), the outer side of a first annular step part at the lower end of the cup shell opening part is welded with the upper end of the cup shell body in the circumferential direction; (3), the cup inner is pressed into the cup shell body and the cup shell opening part, and the top end of the necking part at the upper end of the cup inner and the upper end of the cup shell opening part are kept flush and welded together in the circumferential direction; (4), the outer side of a second annular step part at the upper end of the cup shell bottom is welded with the lower end of the cup shell body in the circumferential direction; and (5), surface polishing treatment is conducted on the welding parts in the step (2), the step (3) and the step (4). By means of the process, the special-shaped double-layer metal vacuum cup can be produced and manufactured in batches, so that the shape and style of the vacuum cup are enriched, and the diversified requirements of consumers for the shape and style of the vacuum cup are met.

Description

technical field [0001] The invention relates to the field of thermos cup production and manufacturing, in particular to a process for producing special-shaped double-layer metal vacuum thermos cups. Background technique [0002] As we all know, the cup body of the vacuum insulation cup is generally composed of a cup shell, a cup liner, and a vacuum interlayer between the cup shell and the cup liner. At present, vacuum thermos cups made of metal materials such as stainless steel and titanium on the market are all round in shape, and the manufacturing process is mature, but the shape and style are too single, and it has been difficult to meet the growing demand for thermos cups from consumers. And the diverse needs of styles. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a process for producing special-shaped double-layer metal vacuum insulation cups, so as to enr...
