Abstract
The utility model discloses a vacuum pumping structure of a titanium alloy vacuum cup, which is characterized by comprising a titanium alloy cup body, wherein the bottom of the titanium alloy cup body is provided with an opening, a welding transition piece is inserted into the opening, the welding transition piece is made of stainless steel, the welding transition piece is hermetically welded with the titanium alloy cup body, a vacuum pumping hole is arranged on the welding transition piece, the vacuum pumping hole is blocked by welding material after vacuum pumping, the welding transition piece comprises a blocking part and a limiting part which are integrally connected, the blocking part extends into the opening, and the limiting part is pressed at the edge of the opening; the advantage is that the opening on the cup is stopped up on welding the cup of stainless steel's welding transition piece on the titanium alloy material earlier, sets up the evacuation hole on welding the transition piece again, seals the vacuum hole with the welding material at last, because the seal stability between stainless steel and the titanium alloy is better, simultaneously the seal stability between stainless steel and this seal is also better, consequently the condition of difficult appearance fracture also can guarantee the permanent seal of shutoff.
Description
Technical Field
The utility model relates to a thermos cup especially relates to a vacuum pumping structure of titanium alloy thermos cup.
Background
The vacuum pumping structure of the existing titanium alloy vacuum cup is the same as that of the traditional stainless steel vacuum cup, the vacuum pumping hole is formed in the bottom of the cup, the vacuum pumping hole is filled with more welding material after vacuum pumping, low-carbon steel is generally selected as a welding core of the welding material, and components such as manganese, silicon, chromium, nickel and the like are added, when the welding material is used as the vacuum cup for filling and plugging the titanium alloy material, the welding stability of the titanium alloy and the welding material is poor, the titanium alloy is easy to crack, so that vacuum failure is caused, the cup body cannot keep a long-term vacuum state, but the welding stability between the stainless steel material and the titanium alloy is good, the cracking condition is not easy to occur, meanwhile, the welding stability between the stainless steel material and the welding material is good, therefore, a transitional welding part needs to be arranged between the titanium alloy cup body and the welding material, so that a good welding effect is achieved with the titanium alloy, prevent cracking and ensure the long-term sealing property of plugging.
Disclosure of Invention
The utility model aims to solve the technical problem that a vacuum pumping structure of a titanium alloy vacuum cup capable of keeping a long-term vacuum state is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides an evacuation structure of titanium alloy thermos cup, includes the titanium alloy cup, the bottom of titanium alloy cup seted up the opening, the opening in fill in the welding transition piece, the welding transition piece be stainless steel, the welding transition piece with titanium alloy cup seal weld, the welding transition piece on be equipped with the evacuation hole, after the evacuation hole usefulness the welding sealing material with its shutoff, the welding transition piece include a body coupling's shutoff portion and spacing portion, the shutoff portion stretch into the opening in, spacing portion press and establish open-ended edge.
The utility model discloses a further preferred scheme does: the limiting part is welded with the titanium alloy cup body.
Compared with the prior art, the utility model has the advantages that the welding transition piece is sealed and welded with the titanium alloy cup body, the vacuumizing hole is arranged on the welding transition piece, the vacuumizing hole is blocked by welding sealing material after vacuumizing, the welding transition piece comprises a blocking part and a limiting part which are connected into a whole, the blocking part extends into the opening, the limiting part is pressed at the edge of the opening, the welding transition piece made of stainless steel is firstly welded on the cup body made of titanium alloy material to block the opening on the cup body, then the vacuumizing hole is arranged on the welding transition piece, finally the vacuum hole is sealed by welding sealing material, because the welding sealing stability between the stainless steel material and the titanium alloy is good, meanwhile, the welding seal stability between the stainless steel material and the welding seal material is good, so that the cracking is not easy to occur, and the long-term tightness of the sealing can be ensured.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an exploded view of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in the figure, an evacuation structure of titanium alloy thermos cup, including titanium alloy cup 1, opening 11 has been seted up to titanium alloy cup 1's bottom, fill in welding transition piece 2 in opening 11, welding transition piece 2 is stainless steel, welding transition piece 2 and 1 seal weld of titanium alloy cup, be equipped with evacuation hole 21 on the welding transition piece 2, evacuation hole 21 will 3 its shutoff with the welding material after the evacuation, welding transition piece 2 includes a body coupling's shutoff portion 22 and spacing portion 23, shutoff portion 22 stretches into in the opening 11, spacing portion 23 presses the edge of establishing at opening 11, spacing portion 23 welds with titanium alloy cup 1.
The welding between the welding transition piece and the titanium alloy cup body in the above embodiment can adopt laser welding, vacuum electron beam welding or brazing and the like.
It is right above the utility model provides a vacuum structure of taking out of titanium alloy thermos cup introduces in detail, and it is right to have used specific individual example herein the utility model discloses a principle and implementation mode have been elucidated, and the explanation of above embodiment is only used for helping to understand the utility model discloses and core thought. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
Claims (2)
1. The utility model provides an evacuation structure of titanium alloy thermos cup, includes the titanium alloy cup, the bottom of titanium alloy cup seted up the opening, the opening in fill in the welding transition piece, the welding transition piece be stainless steel, the welding transition piece with titanium alloy cup seal welding, the welding transition piece on be equipped with the evacuation hole, after the evacuation hole with the welding material with its shutoff, the welding transition piece include a body coupling's shutoff portion and spacing portion, the shutoff portion stretch into the opening in, spacing portion press and establish open-ended edge.
