Processing equipment of 5083 aluminium-alloy thin-wall pipes

Abstract

The invention discloses processing equipment of 5083 aluminium-alloy thin-wall pipes. The processing equipment comprises an internal drum sleeve, a mold bearing, a hollow extruding shaft, an extruding needle and a needle bearing, wherein the inner diameters of the internal drum sleeve, the mold bearing and the hollow extruding shaft are respectively 420mm, and the diameters of the extruding needle and the needle bearing are respectively 210mm; the internal drum sleeve is arranged on the mold bearing; the extruding needle is arranged on the needle bearing; the hollow extruding shaft sleeves the extruding needle. The processing equipment disclosed by the invention has the advantages that since the inner diameters of the internal drum sleeve, the mold bearing and the hollow extruding shaft are respectively 420mm, and the diameter of the extruding needle is 210mm, the cross-section area of an extruding drum cavity formed by the internal drum sleeve and the extruding needle is effectively reduced, and the total cross-section area of an extruded product is not changed, so that the extruding coefficient is effectively reduced, and the blocking phenomenon in the extruding process is reduced; therefore, by the processing equipment provided by the application, the production efficiency of the 5083 aluminium-alloy thin-wall pipes can be improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing equipment, in particular to a processing equipment for 5083 aluminum alloy thin-walled pipes. Background technique [0002] 5083 aluminum alloy is a high-magnesium alloy with good strength, corrosion resistance and machinability among non-heat-treatable alloys. It is widely used in technical fields such as welding parts of ships, automobiles and aircrafts. [0003] The processing equipment for 5083 aluminum alloy thin-walled pipes is used for processing 5083 aluminum alloy thin-walled pipes, wherein the processing equipment includes cylinder inner sleeve, mold support, hollow extrusion shaft, extrusion needle and needle support, wherein cylinder inner sleeve, mold support The inner diameters of the hollow extrusion shaft and the hollow extrusion shaft are both 500 mm, and the diameters of the extrusion needle and the needle support are both 250 mm. The extruding needle is insta...

Problems solved by technology

[0004] However, for pipes with an outer diameter of 100mm-200mm and a wall thickness of 8-12mm, the extrusion coefficient (the ratio of the cross-sectional area of ​​the extrusion cylinder cavity to the total cross-sectional area of ​​the extruded product) is relatively large, resulting in easy extrusion during the extrusion process. The phenomenon of stuffy cars occurs, and the production efficiency of 5083 aluminum alloy thin-walled pipes is low
