A kind of titanium metal thermos cup and the composite metal ring used for making and processing method thereof

Abstract

The invention discloses a titanium metal thermos cup, a composite metal ring for making and a processing method thereof, including a titanium metal ring, a stainless steel ring, and the titanium metal ring and the stainless steel ring are connected by brazing at the ends formed by brazing; Its processing method: processing titanium metal ring and stainless steel ring, degreasing treatment, butt joint through spigot, brazing at the end, vacuuming the layer, and making a titanium metal insulation cup. The invention can save precious titanium metal materials, improve the quality of the titanium metal insulation cup, has simple processing, high production efficiency, further reduced cost, and is suitable for mass production.

Description

technical field [0001] The invention relates to a titanium metal thermos cup, which is used for making a composite metal ring of the titanium metal thermos cup, and a processing method of the composite metal ring. Background technique [0002] The existing metal thermos cup is mainly composed of a stainless steel inner tank and a stainless steel outer shell welded, and a vacuum layer is set between the stainless steel inner tank and the stainless steel outer shell. However, due to the hidden dangers of heavy metal precipitation in the stainless steel inner tank, it is more desirable to replace stainless steel with titanium, which has better corrosion resistance, antibacterial properties, and no heavy metal precipitation. [0003] However, the price of titanium metal is relatively high, so that the thermos cup made entirely of titanium metal not only consumes more titanium metal, but also its high price is not easy to be widely accepted by the market.

AI Technical Summary

Problems solved by technology

[0008] 3. The brazing method of stacking the titanium ring 4 and the stainless steel ring 5 increases the consumption of the expensive titanium ring 4 for the same size;

[0009] Therefore, the technical solution of this patent still has the problem of unstable brazing quality in the mass production of titanium metal thermos cups, and there are still problems such as thick cup mouth, heavy weight, large volume, and relatively high cost in popularization and application.
