Composite vacuum cup and manufacturing process thereof

Abstract

The invention provides a composite vacuum cup and a manufacturing process thereof, and belongs to the technical field of vacuum cups. The technical problems that an existing vacuum cup is low in production efficiency, high in manufacturing cost and the like are solved. The composite vacuum cup comprises a shell and an inner container inserted into the shell, a vacuum layer is arranged between theshell and the inner container, and the inner layer of the inner container is made of titanium or titanium alloy. The inner container is provided with a middle layer made of copper metal or copper alloy or aluminum metal or aluminum alloy and an outer layer made of stainless steel materials, or the inner container is provided with an outer layer made of copper metal or copper alloy or aluminum metal or aluminum alloy, and a welding ring made of stainless steel materials is arranged on the outer surface of the upper end of the outer layer. The manufacturing process of the composite vacuum cup comprises the following steps: a, manufacturing a shell; b, manufacturing an inner container: manufacturing the inner container from a composite board through a plurality of stretching processes; and c,performing assembling. The machining efficiency is improved, and the manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the technical field of thermos cups, and relates to a composite thermos cup and a manufacturing process thereof. Background technique [0002] With the continuous development of people's science and technology, thermos cups, as common daily necessities, can store water or other liquids in heat preservation. The existing thermos cups are usually made of ceramics or stainless steel with a vacuum layer, and there is a heat preservation cover on the top. , tightly sealed, the vacuum layer can delay heat dissipation to achieve the effect of heat preservation. The inner liner of the existing thermos cup is made of stainless steel, and there is a phenomenon of heavy metal precipitation. When used for a long time, it will affect the taste of the drink and easily cause the drink to deteriorate. service life. [0003] In view of the above existing situation, people have developed a variety of thermos cups made of titanium materials: ...

AI Technical Summary

Problems solved by technology

[0005] In the titanium composite thermos cup mentioned in the above-mentioned patent document, the liner of the thermos cup is made of titanium metal, while the metal shell is composed of titanium metal and stainless steel material, and a large amount of titanium metal material will be used, which will make the thermos cup The manufacturing cost has risen sharply; if the shell is made of traditional stainless steel, the welding process of the titanium liner and the stainless steel shell will be relatively difficult, which not only affects production efficiency, but also requires relatively high skill requirements for production equipment and workers. It will also affect the manufacturing cost of the thermos cup
