A processing equipment for partial double alloy composite aluminum profiles

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...

AI Technical Summary

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
