preparation example Construction

[0016] On the one hand, an embodiment of the present invention provides a method for preparing a shaft core wire of a copier, including:

[0017] S01. Provide a carbon steel wire rod, the carbon content of the carbon steel wire rod is 0.18wt%~0.23wt%, the phosphorus content≤0.030wt%, the sulfur content≤0.030wt%, and the aluminum content is 0.030wt%~0.060wt% ;

[0018] S02. Perform a first drawing process on the carbon steel wire to obtain a first drawn product;

[0019] S03. Perform spheroidizing annealing treatment on the first drawn product to obtain a spheroidizing annealing product; the spheroidizing annealing treatment includes: heating the first drawn product to 730-760°C in a protective atmosphere, Keep heat for 2 to 4 hours; cool to 680 to 690°C at a rate of 10 to 20°C / hour for 4 to 6 hours; then, cool to room temperature naturally;

[0020] S04, subjecting the spheroidizing annealing product to a second drawing treatment to obtain;

[0021] Wherein, the second drawing process...

Embodiment 1

[0049] This embodiment provides a method for preparing a shaft wire of a copier, including the following steps:

[0050] S11. Provide a carbon steel wire rod, the composition of the carbon steel wire rod refers to Table 1:

[0051] Table 1

[0052] Content (wt%) carbon0.21 silicon≤0.10 manganese0.90 sulfur≤0.030 phosphorus≤0.030 aluminum 0.030

[0053] Through metallographic microscopic examination, the grain size of the carbon steel wire rod is 7-9, the grains are arranged uniformly, there is no abnormal structure such as coarse grains, Widmanstatten structure, and the ovality of the carbon steel wire rod ≤ 0.20mm .

[0054] S12. The carbon steel wire rod is pickled and phosphated in sequence, and then subjected to a first drawing treatment to obtain a first drawn product;

[0055] During pickling, a hydrochloric acid aqueous solution with a mass concentration of 15% is used for pickling for 20 minutes.

[0056] When phosphating, sodium nitrite is used as an accelerator;

Abstract

The invention belongs to the technical field of copier manufacturing, and particularly relates to a preparation method of a copier axis wire. The preparation method includes the steps that a carbon steel wire is provided, wherein the carbon steel wire is prepared from 0.18 wt%-0.23 wt% of carbon, smaller than or equal to 0.030 wt% of phosphorus, smaller than or equal to 0.030 wt% of sulfur and larger than or equal to 0.020 wt% of aluminum; the carbon steel wire is drawn for the first time, and a first drawing product is obtained; the first drawing product is subjected to spheroidizing annealing, and a spheroidizing annealing product is obtained, wherein spheroidizing annealing includes the procedures that the first drawing product is heated to 730-760 DEG C under the protective atmosphereand then subjected to heat preservation for 2-4 h, the first drawing product is cooled to 680-690 DEG C at the speed of 5-20 DEG C / h and then subjected to heat preservation for 4-6 h, and then the first drawing product is naturally cooled to room temperature; and a second product is drawn for the second time, and the copier axis wire is obtained. A wire drawing die is adopted for second-time drawing, the length of a sizing belt of the wire drawing die is 0.4-0.6 time of the diameter of the carbon steel wire, the working taper angle is 12-14 degrees, and the sizing belt of the wire drawing dieis in a straight barrel shape.

Description

Technical field [0001] The invention belongs to the technical field of copier manufacturing, and in particular relates to a method for preparing a shaft core wire of a copier. Background technique [0002] Speaking of the concept of photocopying, it can be traced back to 1938 when the United States used xerographic technology to print the world's first photocopy document, and "copy" technology began to serve mankind. Since the introduction of the electrostatic copier in the United States in 1959, it has aroused the attention and interest of the information technology circles of all countries in the world. The application of photocopying technology in my country appeared relatively late, and it was not until 1964 that xerographic copiers were used. The copier machinery went through the basic construction phase (1964-1983), the development period (1984-2000), and the digital age (2001-2009). , That is, from black and white to color, from single function to multi-function, from anal...
