Abstract

The utility model discloses a copper aluminum pipe resistance welding connector. One end of a copper pipe is nested into one end of an aluminum pipe. The copper pipe is tightly combined to the aluminum pipe through a connector, and the outer surface of the connector is coated with a high temperature resistant paint layer. The copper pipe is tightly connected with the aluminum pipe through the connector, the part of the copper aluminum pipe at the connector is larger than the aluminum pipe in tensile strength, the connection part is well tight, and the copper aluminum pipe resistance welding connector is low in cost.

Description

Copper aluminum pipe resistance welding joint
Technical field
The utility model relates to the copper aluminum pipe welded joint field.
Background technique
The joint of present copper pipe and aluminum pipe, generally by melting welding, soldering, pressure welding mode joint, but this mode weld tensile strength is not high, and sealing is not high relatively.
Summary of the invention
The structural representation of Fig. 1, this similar copper-aluminium joint resistance welding jointing shown in Figure 2, an end of copper pipe reducing is nested in an end of aluminum pipe, closely links together by jointing, and this jointing is to connect by resistance welding.
After aluminum pipe and copper pipe compress by electrode, by the cylinder upset, high-frequency pulse discharge generation electric current melts aluminum pipe when copper pipe and aluminum pipe clash into mutually, and copper, aluminum pipe copper pipe are closely linked together by connecting head, can preferably be coated with the high temperature resistant paint of one deck in the welding position.
This kind copper-aluminium joint structure has following advantage:
1, its tensile strength of weld copper aluminum pipe is greater than aluminum pipe;
2, the weld sealing is relatively good, and charging into the 2.0Mpa high pure nitrogen in the pipe does not have leakage.
3, the weld internal diameter is consistent with the mother metal internal diameter.
4, satisfy the usage requirement of chiller plant its working life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the copper pipe schematic representation after the enlarging of the present utility model;
Embodiment
The structural representation of this similar copper-aluminium tube joint shown in Figure 1, Fig. 2 are through copper pipe 3 schematic representation after mould reducing, the enlarging.Copper pipe 3 one ends are carried out enlarging one end carry out reducing, and an end of copper pipe 3 reducings is nested in the aluminum pipe 1, be closely linked by jointing 2.
Jointing 2 is to connect by resistance welding, one end of copper pipe 3 reducings is nested in the aluminum pipe 1, and through the mould extruding, copper pipe 3 produces high electric current by resistance when inserting aluminum pipe 1 and under the situation of moment aluminum pipe is melted, combine closely on copper pipe, copper pipe closely is connected with aluminum pipe.
Fusion face 〉=5mm after the welding does not add any soldering flux in welding process, do not have any splash and rubbish and produce, and endoporus cleans bright free from admixture.Protection is played in the weld processing of spraying paint.
Above-described embodiment is for explanation or explains this real model utility, rather than to restriction of the present utility model, improves under the design prerequisite of claims of the present utility model and specification, all belongs to the protection domain of the utility model claims.

Claims (2)

1. copper-aluminium joint, comprise aluminum pipe (1) and and copper pipe (3), one end of copper pipe (3) reducing is nested in an end of aluminum pipe (1), closely links together by jointing (2), it is characterized in that: this jointing (2) is fixing by the welding of resistance welding ways of connecting.
2. copper-aluminium joint according to claim 1 (2) is characterized in that and the outer surface in the joint is coated with the high temperature resistant paint of one deck.
