Problems solved by technology

However, due to the difference in hardness and deformation resistance of the two aluminum alloys that are nested together, and the metal flow is also different at different stages of extrusion, this method has the defect that the thickness of the alloy layer is seriously uneven. , which brings great problems to the brazing of the subsequent condenser. If the composite layer is insufficient, it will cause leakage. If the composite layer is too thick, the parallel flow tube holes will be blocked due to solder flow. Low efficiency and high production cost

Embodiment 1

[0041] Such as figure 1As shown, the present invention provides a processing method 100 for a partial double-alloy composite aluminum profile, the partial double-alloy composite aluminum profile includes a first alloy profile and a second alloy profile, the first alloy profile is extruded by an extrusion machine, and the second The second alloy profile is pre-processed and wound onto the coil. When the first alloy profile is extruded, the second alloy profile is compounded on the first alloy profile. As the second alloy profile is continuously extruded, the second alloy profile The profile is also continuously compounded on the surface of the first alloy profile under the rotation of the coiling disc to form the final partial double-alloy composite aluminum profile.

[0042] The processing method 100 includes:

[0043] Forming step 101: extruding and forming the first alloy profile with an extruder;

[0044] Feeding step 102: winding the pre-processed second alloy profile on...

Embodiment 2

[0052] The difference between this embodiment and the first embodiment is that the compounding step also includes a pressing process.

[0053] Processing method 100 in the present embodiment, as figure 2 As shown, the details are as follows:

[0054] Forming step 101: extruding and forming the first alloy profile with an extruder;

[0055] Feeding step 102: winding the pre-processed second alloy profile on the coil, and transporting the second alloy profile to the extrusion position of the first alloy profile through the coil wound with the second alloy profile;

[0056] Composite step 103: when the first alloy profile is extruded, the second alloy profile immediately covers the surface of the first alloy profile, so that the second alloy profile adheres to the first alloy profile under the residual temperature of the first alloy profile surface, thereby compounding the first alloy profile and the second alloy profile together;

[0057] Punching step 104: After the first a...

Abstract

The invention provides a processing method for a local dual-alloy compound aluminum profile. The local dual- alloy compound aluminum profile comprises a first alloy section bar and a second alloy section bar. The processing method comprises the following steps: forming: acquiring the first alloy section bar by extrusion forming; compounding: immediately covering the surface of the first alloy section bar with the second alloy section bar when the first alloy section bar is extruded, thereby bonding the second alloy section bar on the surface of the first alloy section bar under the residual processing temperature of the first alloy section bar, namely, compounding the first alloy section bar with the second alloy section bar. The residual processing temperature of the first alloy section bar is utilized to bond the second alloy section bar to the surface of the first alloy section bar, no independent fixing structure is required, no repeated intermediate annealing is required, and theproblem of uneven thickness of the processed compound aluminum profile caused by the differences in hardness, non-deformability, and the like, of two alloys can be avoided, so that the processing method has the advantages of few and simple processes and high processing efficiency.

Description

technical field [0001] The invention relates to a processing method for aluminum profiles, in particular to a processing method for partial double-alloy composite aluminum profiles. Background technique [0002] With the advancement and development of air-conditioning and refrigeration technology, especially the wide application of brazing technology for all-aluminum microchannel condensers and evaporators, the demand for double-alloy composite aluminum tubes used as headers is also increasing. At present, the relatively mature processing method of double-alloy composite aluminum tube is to combine two different aluminum alloys into a double-alloy plate by rolling, and then curl it into a tube on a complex high-frequency welding machine and use high-frequency welding. The method is to make a double-alloy composite aluminum tube. The double-alloy composite aluminum tube manufactured by this method has the advantages of uniform thickness and stable quality of the composite la...
