Abstract
The utility model discloses a kind of structure that copper pipe is connected with sheet metal component, including copper pipe, copper sheathing and the sheet metal component for installing copper pipe, the copper sheathing is inlayed in the flange metal plate aperture of the sheet metal component, the copper pipe is mounted in the copper sheathing, and the copper pipe is not contacted in flange side with flange metal plate aperture by copper sheathing realization.The utility model completely cuts off copper pipe and metal plate by copper sheathing, would not be damaged by the burr in flanging bore when copper pipe penetrates copper sheathing from the other side, guarantees copper pipe quality, to ensure that the quality of air-conditioning.
Description
Technical field
The utility model relates to air-conditioning equipment package technique fields, and in particular to a kind of connection knot of copper pipe and sheet metal component
Structure.
Background technique
In air-conditioning equipment, there is copper pipe that the stamping holes on sheet metal component is needed to be assembled, and the most punching press of stamping holes
Molding is easy to produce burr in the flange side that it is formed, and when copper pipe is penetrated from the other side, is easy to be damaged by burr.
Utility model content
The purpose of this utility model is the copper provided in a kind of air-conditioning equipment for technological deficiency existing in the prior art
The connection structure of pipe and sheet metal component.
It is for technical solution used by realization the purpose of this utility model:
A kind of structure that copper pipe is connected with sheet metal component, including copper pipe, copper sheathing and the sheet metal component for installing copper pipe, the metal plate
The copper sheathing is inlayed in the flange metal plate aperture of golden part, the copper pipe is mounted in the copper sheathing, and the copper pipe passes through the copper
Set is realized and is not contacted in flange side with flange metal plate aperture.
Be in contact with the hole wall in the flange metal plate aperture height of part of the outer wall of the copper sheathing is at least 2mm.
The utility model completely cuts off copper pipe and metal plate by copper sheathing, would not be turned over when copper pipe penetrates copper sheathing from the other side
Burr damage in lateral opening, guarantees copper pipe quality, to ensure that the quality of air-conditioning.
Detailed description of the invention
Fig. 1 is the schematic diagram of existing copper pipe Yu sheet metal component connection structure；
Fig. 2 is the utility model copper pipe and sheet metal component attachment structure schematic diagram.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 2, a kind of connection structure of copper pipe and sheet metal component, including copper pipe 3, copper sheathing 2 and installation copper pipe
Sheet metal component, copper pipe are mounted in the flange metal plate aperture 1 for having inlayed the sheet metal component of copper sheathing, the flange side opening mouth of flange side stamping holes
Copper sheathing is inlayed, so that copper pipe does not contact with flange metal plate aperture in the flange side in flange metal plate aperture and forms a kind of isolation.
The copper sheathing can completely cut off the friction between copper pipe and metal plate, this structure can be used for the changing in air-conditioning by copper cover inlay
The metal plate flanging metal plate aperture of hot device and the contact position of copper pipe.
Preferably, be in contact with the hole wall in the flange metal plate aperture height h of part of the outer wall of the copper sheathing is at least 2mm.
Preferably, there are 0.05 to 0.07mm distance for the copper sheathing and flanging bore contact surface.
As shown in Fig. 2, using 7.0 inner screw thread copper pipe of TP2M φ for example, designing a outer diameter is φ 7.94*0.5's
Copper sheathing (copper sheathing inner wall light requirement is sliding, copper sheathing inside and outside wall do not allow there are impurity), one of this copper sheathing is made into speaker hole, facilitates fixation
The flange metal plate aperture of sheet metal component hole flanging direction it is reversed, the flange metal plate aperture size of sheet metal component is φ 8mm, copper sheathing with
There are the gap of 0.06mm, operators, and copper sheathing need to be beaten to the flange metal plate into sheet metal component for the contact surface of flanging bore on sheet metal component
It in golden aperture, installs after stablizing, then copper pipe is penetrated, and then carries out heat exchanger production technology.
When processing, first then copper pipe is interspersed in by the copper cover inlay of machine-shaping in the flanging bore of sheet metal component
In copper sheathing, finally by copper pipe and copper sheathing swelling, such copper pipe will be contacted no longer with sheet metal component.
Copper sheathing is inlayed in the flange metal plate aperture that the utility model passes through sheet metal component, when copper pipe penetrates flange metal plate from the other side
When in golden aperture, it will not be damaged by the burr in flange metal plate aperture, ensure that the quality of copper pipe, to ensure that air-conditioning
Quality.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
