Embodiment Construction

[0019] The drafting roller manufacturing process of this embodiment includes the following steps: Step 1. Put the alloy steel material into a heating furnace for preheating for two hours. The roller shaft of the required size is obtained by rough machining, and the error range of the rough machining is between 0.2mm-0.3mm;

[0020] Step 2: Carry out quenching and tempering treatment on the roller shaft obtained after rough machining, so as to make it reach the HB270-320 specification. ;

[0021] Step 3. Put the roller shaft in the nitrogen-oxygen compound furnace, treat it at 570°C for 4 hours, and finish the adjusted roller shaft through the turning machining center to obtain the required size of the roller shaft. The error range of the finishing process is 0.05 Between mm-0.1mm;

[0022] Step 4: Use a grinding machine to rough grind the roller shaft obtained after finishing, and then use a high-precision grinding machine to perform fine grinding and then perform a finishin...

Abstract

The invention discloses a drawing roller manufacturing technology and relates to a metal shaft manufacturing technology. The drawing roller manufacturing technology aims at solving the problems that a drawing roller in the prior art is poor in wear resistance and corrosion resistance and high in fatigue, yarn scraping is likely to be caused in the spinning work, and the production precision and the production efficiency are reduced. The drawing roller manufacturing technology includes the following steps that a roller shaft with the needed size is obtained by roughly machining an alloy steel material; quenching and tempering treatment is conducted on the roller shaft obtained after rough machining; finish machining is conducted on the roller shaft obtained after quenching and tempering, and the roller shaft with the needed size is obtained; the roller shaft obtained after finish machining is subjected to rough grinding and accurate grinding, polishing treatment is conducted, and therefore the roller shaft can reach the tolerance of a finished product; ultrasonic cleaning is conducted; liquid nitrogen surface treatment is conducted; and detecting and correcting are conducted. The problems that precision is poor and the yarn forming quality is poor in the production process are solved thoroughly.

Description

technical field [0001] The invention relates to a metal shaft manufacturing process, in particular to a drafting roller manufacturing process, and belongs to the technical field of textile machinery processing. Background technique [0002] The drafting roller is the main part of the drafting mechanism of the spinning machine. The upper roller and the lower roller are paired to form a roller nip, which holds the yarn for drafting. The quality of the rollers affects the uniformity of the output sliver. At present, most of the drafting rollers used in the market are made of stainless steel or stainless iron, which has low hardness, poor precision in the production process, poor surface anti-corrosion technology, easy to rust and wear, which seriously affects the production accuracy and yarn quality. . Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art that the drafting roller has poor wear resistance and corros...
