The aluminum-based tube is processed by a grinding wheel grinder. The abrasive material is natural corundum, artificial corundum or artificial corundum. The particle size of the abrasive material ranges from 20 mesh to 360 mesh. The linear speed of the polishing wheel is 18-25m / s. The tube blank is subjected to rough grinding, medium grinding, and fine grinding to remove macroscopic defects on the circumferential surface of the aluminum-based tube, and the roughness is within 1.5 μm.

Embodiment 3

[0030] The present organic photoconductor consists of an aluminum base tube, such as image 3 As shown, the circumferential surface of the aluminum base tube is smooth and the circumferential surface is formed with an axial drawing line, the length of the drawing line is ≤ 500 μm, and the radial micro-fracture crystal structure caused by drawing, the micro-fracture crystal structure The length of the tissue is ≤ 100 μm. The aluminum-based tube is obtained by precision cold drawing. Before the precision cold-drawing, the aluminum ingot used to form the aluminum-based tube blank is subjected to 500-600°C for 8-12 hours of homogenization, and then is extruded through a split-flow combination die and quenched with strong wind. The hot-extruded tube is subjected to aging treatment at 150-300°C for 10-20 hours, and then precision cold-drawn. The concentricity and straightness of the precision cold-drawn tube are within 0.05mm, and the surface roughness of the circumference is within...

Abstract

The invention discloses an organic optical conductor, comprising an aluminum base tube, wherein discontinuous grinding cracks are formed in the circumferential surface of the aluminum base tube; or radial lines distributed in a staggered mode are formed on the circumferential surface; or axial drawing lines and radial micro-fracture crystal form textures caused by drawing are formed on the circumferential surface; or a layer of uniform microporous oxide film is formed on the circumferential surface; or staggered lines and a small amount of pores are formed on the circumferential surface; or microporous lines formed by extrusion are formed on the circumferential surface. The organic optical conductor disclosed by the invention is long in service life and uniform in electricity distribution, the electric potential deviation is less than 8%, the density inhomogeneity of a printed product is not more than 10%, and because an aluminum base tube blank is obtained by adopting a non-chipping process, the utilization ratio of an aluminum material can be improved.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to an organic photoconductor. Background technique [0002] Aluminum-based tubes are the base material for laser organic photoconductors. The processing method of the circumferential surface of the aluminum-based tube is the main factor affecting the utilization rate of aluminum and the smoothness of the circumferential surface of the aluminum-based tube; the organic photoconductor drum made of aluminum-based tubes is in constant charge when used in laser printers or copiers. Under the working environment of discharge, and it is required to continuously output high-quality and flawless manuscripts, there are certain requirements for the circumferential surface state of the aluminum base tube and the uniformity of charge distribution. Such as Figure 7 As shown, there are some defects in the surface state of the existing threaded aluminum base pipe circumference, such as difficul...
