Embodiment 1

[0028] Embodiment 1 A vacuum insulation cup liner, which is characterized in that the liner 1 is a stainless steel-titanium alloy composite layer, that is, the inner surface 11 of the liner is made of titanium alloy, and the outer surface 12 of the liner is made of titanium alloy. Made of stainless steel.

[0029] Among them, in order to facilitate the sealing between the inner tank and the outer shell, the inner tank is made of stainless steel material at the mouth and extends upwards separately to form a welded part that is brazed and sealed with the outer shell, thereby facilitating the welding of the outer shell and the inner tank.

Embodiment 2

[0030] Embodiment 2 A vacuum insulation cup, including a stainless steel shell 2 and an inner tank 1, the inner tank 1 is as shown in Embodiment 1, the inner tank 1 is coaxially sleeved in the outer shell 2, and forms a gap with the outer shell 3. The mouth of the liner is sealed integrally with the outer shell through a brazing process.

[0031] Among them, the bottom of the vacuum shell is reserved with an exhaust hole 21. During the processing of the vacuum cup, the vacuum equipment vacuumizes the cavity of the gap 3 through the exhaust hole 21 to form a vacuum chamber, and then the exhaust hole 21 passes through the brazing Flux sealed.

[0032] Wherein, the liner processing technology in embodiment 1 and 2 comprises steps such as necking, spin thinning, high temperature crystallization, wherein,

[0033] Shrinking means that the composite liner is fixed in the shrinking mold to expose the main body of the mouth to be shrunk, and then the top of the shrinking machine is p...

Abstract

The invention discloses a vacuum cup inner container and a processing technology thereof. The inner container (1) is a stainless steel-titanium alloy composite layer; an inner surface (11) of the inner container is made of a titanium alloy material; an outer surface (12) of the inner container is made of a stainless steel material; a vacuum cup includes a housing and the inner container; the innercontainer is the inner container (1) of the claim 1; the inner container (1) is coaxially sleeved with the housing (2), and a gap (3) is formed between the inner container (1) and the housing; and amouth of the inner container and the housing are sealed into a whole through a brazing process. The inner container disclosed by the invention adopts the design of a stainless steel-titanium alloy composite structure, and through necking, rotary thinning and high-temperature crystallization processes, not only is the high quality of the titanium alloy inner container kept, but also the sealing performance problem of the inner container and the housing is solved.

Description

technical field [0001] The invention relates to the field of mouth cups, in particular to a vacuum insulation cup liner and a processing technology. Background technique [0002] At present, the cup body of the vacuum insulation cup on the market is mostly made of stainless steel shell, and the inner tank is mainly made of stainless steel inner tank or titanium alloy inner tank. When the outer shell is made of stainless steel, if the inner tank is made of titanium alloy material, brazing is used. After the process is sealed, there will be problems such as seal falling off or poor sealing. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a vacuum insulation cup liner and its processing technology. The high quality of the liner solves the sealing problem between the liner and the shell. [0004] In order to achieve the above object, the present invention adopts the following technical solutio...
