preparation example Construction

[0016] In one aspect, the embodiment of the present invention provides a method of preparing a copier shaft strobe, including:

[0017] S01, providing carbon steel wire, the carbon content of the carbon steel wire is 0.18 wt% to 0.23% by weight, the phosphorus content is ≤0.030 wt%, the sulfur content is ≤0.030 wt%, the aluminum content is 0.030% by weight to 0.060% by weight. ;

[0018] S02, the carbon steel wire is first drawn, and the first pull-out product is obtained;

[0019] S03, the first pull-down product is subjected to a spheroidized annealing product; the spheroidal annealing treatment comprises: thawing the first pulling product to 730 to 760 ° C under a protective atmosphere. Insulation 2 to 4 hours; cool to 680 to 690 ° C at a speed of 10 to 20 ° C / h, heat insulation for 4 to 6 hours; then naturally cooled to normal temperature;

[0020] S04, the spheroidal annealing product is drawn, that is,

[0021] Wherein, the second draw treatment is drawn by a brigadier mol...

Embodiment 1

[0049] The present embodiment provides a method for preparing the axis of the copying machine wire, comprising the steps of:

[0050] S11, providing carbon steel wire, carbon steel wire rod component of the composition of Reference Table 1:

[0051] Table 1

[0052] Content (wt%) carbon 0.21 silicon ≤0.10 manganese 0.90 sulfur ≤0.030 phosphorus ≤0.030 aluminum 0.030

Abstract

The invention belongs to the technical field of duplicator manufacturing, and in particular relates to a method for preparing shaft core wires of copiers, comprising: providing carbon steel wires, the carbon content of which is 0.18wt%-0.23wt%, and the phosphorus content≤0.030wt% , sulfur content ≤ 0.030wt%, aluminum content ≥ 0.020wt%; the carbon steel wire rod is subjected to the first drawing treatment to obtain the first drawn product; the first drawn product is subjected to spheroidizing annealing treatment to obtain spheroidizing annealing Product; the spheroidizing annealing treatment includes: under a protective atmosphere, the temperature of the first drawn product is raised to 730-760°C, and kept for 2-4 hours; cooled to 680-690°C at a rate of 5-20°C / hour, and kept for 4 hours ~ 6 hours; after that, naturally cool to normal temperature; the second product is subjected to the second drawing treatment to obtain final product; wherein, the second drawing treatment adopts a wire drawing die, and the length of the sizing zone of the wire drawing die is the diameter of the carbon steel wire rod 0.4 to 0.6 times of that, the working cone angle is 12 to 14°, and the sizing belt part of the drawing die is in the shape of a straight cylinder.

Description

Technical field [0001] The present invention belongs to the field of printing machine manufacturing, and is specifically related to the preparation method of a photocopharamid wire. Background technique [0002] Speaking of the concept of copying, can be traced back to 1938, the United States uses electrostatic copying techniques to print the world's first copy file, "copy" technology begins to serve human services. Since 1959, the static photocopier came in the United States, causing attention and interest in the information technology community of all countries around the world. my country's copying technology application has been relatively late. From 1964, it began to use electrostatic copiers. The copier machinery has experienced the basic construction stage (1964-1983), the development period (1984-2000), digital age (2001-2009) It is also from black and white to color, from single function to multi-function, from simulation technology to digital, networked road development...
