Abstract
The invention discloses an aluminum alloy tube of a photoconductor drum, and a production method and equipment thereof. The aluminum alloy tube of the photoconductor drum is composed of the following chemical components in percentage by weight: 1.1-1.3% of Mn, 0.06-0.10% of Cu, not higher than 0.06% of Si, higher than 0.15% and not higher than 0.20% of Fe, higher than 0.01% and not higher than 0.03% of impurity elements and the balance of Al. The production method of the aluminum alloy tube comprises the following steps of: selecting ingot blank, smelting, refining, online refining, online degassing, primary filtering, secondary filtering, casting, homogenizing annealing, induction heating of cast ingot, online hot peeling of the cast ingot, constant-speed isothermal extrusion and drawingand finishing, wherein the drawing and finishing process employs limit drawing and similar drawing. The aluminum alloy tube of the photoconductor drum produced by the production method disclosed by the invention has the advantages of low impurity content, high dimensional precision of the tube and the like.
Description
technical field [0001] The invention relates to an aluminum alloy tube, in particular to a photosensitive drum aluminum alloy tube used in fax, copying, and electrophotographic equipment, and a production method and equipment thereof. Background technique [0002] With the continuous improvement of the metallurgical process and precision machining technology level of aluminum alloys, the application and popularization of aluminum alloy pipes in the fields of electronics and communication engineering is accelerating. The aluminum alloy tube of the photosensitive drum is a key component of fax, photocopying and electrophotographic equipment. Aluminum alloy tubes produced by traditional processes usually have problems such as high impurity content and low dimensional accuracy, which not only directly affect the effect of image information faxing and copying, but also affect the working life of the entire electronic communication equipment. Therefore, not only the dimensional a...
