Production technology of aluminum alloy circular pipe for producing photosensitive drum of fine definition laser printer

Abstract

The invention discloses a production technology of an aluminum alloy circular pipe for producing a photosensitive drum of a fine definition laser printer. The aluminum alloy circular pipe contains: by mass, 0.04 to 0.25% of Si, 0.30 to 0.65% of Fe, 1.0 to 1.15% of Mn, 0.07 to 0.25% of Cu, less than or equal to 0.10% of Zn, less than or equal to 0.15% of other impurities and the rest of Al. The production technology comprises the following processes of a melting process, an ingot casting process, a homogenizing annealing process, a hot extrusion process, a drawing process, etc. Through the production technology, an aluminum alloy circular pipe which has a high quality, no surface defects produced by an anodization process and a fine crystalline grain size, and is utilized for a photosensitive drum of a fine definition laser printer is produced stably, and a photosensitive drum made of the aluminum alloy circular pipe has a high quality, a high yield and a low light reflectivity of 0.6 to 0.7%.

Description

technical field [0001] The invention relates to a production process of an aluminum alloy round tube, in particular to a production process of an aluminum alloy round tube for a photosensitive drum of a high-definition laser printer. Background technique [0002] The photosensitive drum is the core component of the laser printer, which is used as a consumable material in the laser printer, and its price is relatively expensive. The photosensitive drum used in laser printers is made by coating a layer of photoconductor material on an aluminum alloy round tube (drum base material), and coating a layer of insulating material outside the photoconductor coating. The aluminum alloy round tube is the conductive layer of the photosensitive drum, which is connected to the ground wire of the laser printer, so that the potential after exposure can be released quickly. The quality requirements of aluminum alloy round tubes are very high, there are no defects on the surface, and the gra...

Problems solved by technology

However, an obvious disadvantage of 3003 aluminum alloy is that if the process is not properly controlled, coarse grains are prone to appear on the surface of the processed pipe.

The photosensitive drum made of this kind of tube with coarse grains has high reflectivity to light, which affects photoelectric conversion and reduces printing quality
