Abstract
The utility model relates to a kind of idle call system pipeline parts, more particularly to a kind of metal tube of rotation press closing, including metal tube body, the metal tube body is hollow structure, it is equipped with spinning arc sealing end at the metal tube body both ends, solder is filled at the shrinkage cavity of the spinning arc sealing end.Preferably, several mounting holes are equipped on the side wall of the metal tube body.A kind of metal tube of rotation press closing of the utility model, the sealing cap of the prior art is cancelled, and it directlys adopt and carries out rotation press closing in metal pipe end opening, hollow metal tube can generate shrinkage cavity in sealing end during rotation press closing, for the air-tightness for ensureing metal tube, the utility model, which is used, fills solder in shrinkage cavity position.Cost of goods manufactured will be effectively reduced using this structure and improve the production efficiency of product, product quality also has higher promotion.
Description
Technical field
The present invention relates to a kind of idle call system pipeline part more particularly to a kind of metal tubes of rotation press closing.
Background technique
Existing heat exchanger connection collector majority is the metal tube of both ends sealing, such as patent publication No. CN206627011U mono-
Kind heat exchanger connection collects effective plug, it is also the common pipeline structure of air-conditioning system, and the technology that it is used is in pipe end
Mouth welds a hemispherical plug body to realize the port sealing to metal tube, is existing skill using hemispherical plug body or sealing cap
The common method that art uses, it needs welder that hemispherical plug body or sealing cap are welded to metal pipe end opening, and still, heat exchanger connects
Connect that collector is generally all relatively thick and wall thickness is thicker, welding difficulty is larger and production efficiency is lower, and products air tightness also cannot get
It ensures.
Summary of the invention
Present invention aims to overcome that the problems of the above-mentioned prior art and a kind of high production efficiency and product matter are provided
Measure the metal tube of excellent rotation press closing.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of metal tube of rotation press closing, including metal tube body, the metal tube body is hollow structure, in the gold
Belong to tube body both ends and be equipped with spinning arc sealing end, solder is filled at the shrinkage cavity of the spinning arc sealing end.
Preferably, several mounting holes are equipped on the side wall of the metal tube body.
Compared with prior art, the invention has the benefit that
A kind of metal tube of rotation press closing of the present invention, the sealing cap of the prior art is cancelled, and directlys adopt in metal tube
Port carries out rotation press closing, and hollow metal tube can generate shrinkage cavity in sealing end during rotation press closing, to ensure metal tube
Air-tightness, the present invention use shrinkage cavity position fill solder.Cost of goods manufactured and raising will be effectively reduced using this structure
The production efficiency of product, product quality also have higher promotion.
Detailed description of the invention
Fig. 1 is schematic diagram of the three-dimensional structure；
Fig. 2 is schematic view of the front view of the present invention；
Fig. 3 is side structure schematic view of the present invention.
Specific embodiment
Referring to shown in attached drawing 1-3, a kind of metal tube of rotation press closing, including metal tube body 1, the metal tube body 1
For hollow structure, it is equipped with spinning arc sealing end 2 at 1 both ends of metal tube body, in the spinning arc sealing end 2
Solder is filled at shrinkage cavity 3.
Preferably, several mounting holes 4 are equipped on the side wall of the metal tube body 1.
A kind of metal tube of rotation press closing of the present invention, the sealing cap of the prior art is cancelled, and directlys adopt in metal tube
Ontology 1 forms spinning arc sealing end 2, meeting during rotation press closing of metal tube body 1 of hollow structure by spinning apparatus
There are shrinkage cavities 3 at spinning arc sealing end 2, and for the air-tightness for ensureing metal tube, the present invention is used in spinning arc sealing end 2
Shrinkage cavity 3 at be filled with solder.It is for exchanging heat with air-conditioning system that several mounting holes 4 are equipped on the side wall of metal tube body 1
Device piping connection will be effectively reduced cost of goods manufactured using this structure and improve the production efficiency of product, and product quality also can
There is higher promotion.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
