Description
Technical Field
The utility model relates to a composite metal ring for making titanium metal thermos cup.
Background
The existing metal vacuum cup is mainly formed by welding a stainless steel inner container and a stainless steel shell, and a vacuum layer is arranged between the stainless steel inner container and the stainless steel shell. However, since the stainless steel inner container has a risk of heavy metal precipitation, it is more desirable to replace stainless steel with titanium, which has better corrosion resistance and antibacterial property and does not precipitate heavy metals.
However, the price of titanium metal is high, so that the vacuum cup made of titanium metal not only consumes more titanium metal, but also has high price which is not easily accepted by the market widely.
Chinese patent ZL201310692540.6 discloses a titanium alloy composite vacuum cup, and Chinese patent ZL201420047402.2 discloses a titanium alloy inner container vacuum cup, wherein the two vacuum cups both use titanium metal as an inner container and stainless steel as an outer shell, so that the use amount of the titanium metal is greatly reduced, and the vacuum cup is a better technical scheme. However, the inner container and the shell of the two patents are connected together in a complex inserting and fastening mechanical sealing mode or structure, and have adverse effects on the reliability and the service life of the vacuum cup under the conditions of collision, falling and the like; in addition, the titanium metal inner container is directly and tightly contacted with the stainless steel sealing body shell to form heat conduction, so that the heat insulation effect is reduced.
Chinese patent ZL201820780404.0 discloses a double-layer vacuum vessel compounded by pure titanium and stainless steel, which comprises a pure titanium inner container 1 and a stainless steel outer container 2, wherein a vacuum layer 3 is arranged between the pure titanium inner container 1 and the stainless steel outer container 2, a titanium ring 4 is arranged on the outer ring of the opening of the pure titanium inner container 1, a stainless steel ring 5 is arranged on the inner ring of the opening of the stainless steel outer container 2, the contact surface of the titanium ring 4 and the stainless steel ring 5 is fixed in a sealing mode through brazing, and the brazing adopts high-temperature paste-shaped solder. The brazing described in this patent has two structures in common: the first brazing structure is that the lower part of the titanium ring 4 is provided with an annular groove 6, the upper part of the stainless steel ring 5 is provided with an annular bulge 7, and the annular bulge 7 can be embedded into the annular groove 6 and attached to the annular groove; the second brazing structure is that the titanium ring 4 is positioned above the stainless steel ring 5, the bottom end of the titanium ring 4 is provided with an annular sealing plate 8 which is turned outwards, and the annular sealing plate 8 and the top end surface of the stainless steel ring 5 are sealed and fixed in a brazing mode. Compared with the prior art, the technical scheme has the following advantages: firstly, the inner container is made of pure titanium materials, and the outer container is made of stainless steel materials, so that the material cost is reduced; secondly, the outer ring of the opening of the pure titanium inner container is provided with a titanium ring, the inner ring of the opening of the stainless steel outer container is provided with a stainless steel ring, and the contact surface of the titanium ring and the stainless steel ring is sealed and fixed in a brazing mode, so that the stainless steel and the pure titanium form a metallurgical interface, the problems of pseudo bonding and weld bead gap are avoided, the bonding strength is higher than that of a mechanical bonding mode (such as screw locking, gluing and riveting), the bonding strength of the pure titanium and the stainless steel can be effectively improved, and the equipment cost can be reduced. The patent solves the health and safety problem of drinking water, reduces the cost of the vacuum cup, and is a better technical scheme. However, the two brazing structures of the vacuum cup liner and the vacuum cup shell are relatively thin (the wall thickness is usually about 0.3 mm, and the wall thickness of the lightweight vacuum cup is 0.08-0.12 mm), so that the following defects exist in practical application:
firstly, the realization difficulty is large: the thickness of the cup mouth of the vacuum cup cannot be too thick, so that the wall thickness of the titanium ring 4 and the stainless steel ring 5 is determined to be thinner, no matter the first brazing structure or the second brazing structure is adopted, in the melting process of brazing, the laminated brazing mode of the first brazing structure and the second brazing structure often has defects such as local penetration, thin fusion and the like, and therefore the bonding strength and the air tightness are influenced; in order to increase the brazing strength, the technical scheme of the patent can only passively adopt the combination strength taught by the patent that the combination strength is higher than that of a mechanical combination mode (such as screw locking, gluing and riveting) so as to improve the combination strength of pure titanium and stainless steel;
secondly, the thickness of the cup mouth is increased: in order to overcome the defects of local penetration, thin fusion and the like and improve the brazing quality, the wall thicknesses of the titanium ring 4 and the stainless steel ring 5 can be increased, so that the thickness of the cup mouth of the vacuum cup is increased, and particularly in the first brazing structure, the thickness of the cup mouth is equal to the thickness of a pure titanium inner container 1, the thickness of a stainless steel outer container 2, the thickness of the titanium ring 4 and the thickness of the stainless steel ring 5, so that the weight and the integral volume of the cup body are increased, the material is wasted, and the cost is increased;
thirdly, the titanium ring 4 and the stainless steel ring 5 are in a stacked brazing mode, the same size is achieved, and the using amount of the expensive titanium ring 4 is increased;
therefore, the technical scheme of the patent still has the unstable problem of brazing quality on the mass production of titanium metal thermos cups, still has the rim of a cup thick, the weight is heavier, the volume is great, cost is higher scheduling problem relatively in popularization and application.
