Abstract

The invention provides a processing device for a local dual-alloy compound aluminum profile. The processing device comprises an extruding machine and a conveying device, wherein the extruding machineis used for processing a first alloy section bar; a mould for forming the first alloy section bar is arranged in the extruding machine; the conveying device is used for conveying a second alloy section bar; the conveying device comprises a coiling plate used for winding the second alloy section bar; the coiling plate is moveably and rotatably arranged; when the first alloy section bar is continuously extruded, the second alloy section bar is continuously conveyed to and compounded on the surface of the first alloy section bar; the second alloy section bar is conveyed by the coiling plate to anextruding outlet of the first alloy section bar; the second alloy section bar is adhered to the surface of the first alloy section bar under the effect of gravity and is bonded to the surface of thefirst alloy section bar under the residual processing temperature of the first alloy section bar, so as to finish the compounding of two alloys. Such a processing manner has the advantages of few andsimple processes, high processing efficiency, low defective percentage, less raw material consumption and low processing cost.

Description

technical field

[0001] The invention relates to processing equipment for aluminum profiles, in particular to processing equipment for partially 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 composit...

Examples

Embodiment 1

[0053] Such as Figure 7 As shown, 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 extruder, and the second alloy profile is pre-processed and wound onto a coil. When an alloy profile is extruded, the second alloy profile is compounded on the first alloy profile, and as the second alloy profile is continuously extruded, the second alloy profile is also continuously compounded on the first alloy profile under the rotation of the coiling disc surface to form the final local double-alloy composite aluminum profile.

[0054] The processing method 100 includes:

[0055] Forming step 101: extruding and forming the first alloy profile with an extruder;

[0056] 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 pro...

Embodiment 2

[0064] The difference between this embodiment and the first embodiment is that the compounding step also includes a pressing process.

[0065] Processing method 100 in the present embodiment, as Figure 8 As shown, the details are as follows:

[0066] Forming step 101: extruding and forming the first alloy profile with an extruder;

[0067] 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;

[0068] 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;

[0069] Punching step 104: After the first a...
