Problems solved by technology

[0002] At present, the wear-resistant lubricating parts of the sewing machine, especially the needle plate and the sewing machine head, which rub against the cloth on the sewing machine table, are usually galvanized, or treated with paint or plastic spraying. When making clothes, it will make the material being sewn sticky, poor lubricity, and surface wear resistance is poor, it is easy to be scratched by scissors and other metal parts, affecting the sewing operation
In addition, all sewing machines now need lubricating oil. If the seal is not good, the lubricating oil in the sewing machine will leak and pollute the clothes being sewn.

Embodiment 1

[0008] The surface treatment method of a sewing machine wear-resistant lubricating part described in this embodiment is to clean the surface of the needle plate of the sewing machine workpiece using zinc alloy as the base material with lye, and heat it to 120 ° C to remove oil and rust, and then Sandblasting is performed to form a sand surface on the treated surface, and then the commercially available TF-03101M Teflon paint is sprayed on the sandblasted surface, and then heated at 190°C for reinforcement and drying, and then sintered at a high temperature of 360°C. Take it out from the hot furnace and cool it down naturally to obtain a sewing machine needle plate that is both wear-resistant and lubricated after surface treatment. Here, the selected TF-03101M Teflon can be composed of 90.9 parts of tetrafluororesin, 8.1 parts of silicone, 0.8 parts of polyurethane, 0.02 parts of fluosilicic acid,

Embodiment 2

[0010] The surface treatment method of a sewing machine wear-resistant lubricating part described in this embodiment is to first use steel as the base material of the sewing machine transmission workpiece, clean the surface with lye, and heat it to 150 ° C to remove oil and rust, and then spray Sand can be sprayed with 280-mesh corundum to form a sandy surface on the treated surface, and then sprayed on the sandblasted surface with commercially available super-grade TF-03101M Teflon paint, and then heated at 210°C to reinforce and dry, and then It is sintered at a high temperature of 400°C, cooled naturally after being taken out of the furnace, and a sewing machine transmission workpiece that is both wear-resistant and lubricated after surface treatment is obtained. Here, the selected TF-03101M Teflon can be composed of 91.99 parts of tetrafluororesin, 7.2 parts of silicone, 0.8 part of polyurethane, and 0.01 part of fluosilicic acid.

Abstract

The invention discloses a kind of surface processing method for sewing machine wearing and lubricating components. The method cleans the component with alkali solution, and heats it to 120deg.C - 150deg.C, and deoil, derusting, and adds with sprayed sand, thus the processed surface is turned into sand surface. Then uses TF-03101M Teflon paint to paint the sand surface, and they are hardened and solidified under 200 minus or plus 10 deg.C, and they are sintered under 380 minus or plus 20deg.C, it is cooled naturally after being taken out from the furnace. The product has a high wearing property, good lubricating ability, it can save the lubricate oil. It realizes: no abrasion, low stress, non-heating, low noise, no damage, no contamination.

Description

technical field [0001] The invention relates to a surface treatment method for mechanical parts, in particular to a surface treatment method for wear-resistant lubricating parts of sewing machines. technical background [0002] At present, the wear-resistant lubricating parts of the sewing machine, especially the needle plate and the sewing machine head, which rub against the cloth on the sewing machine table, are usually galvanized, or treated with paint or plastic spraying. When making clothes, it will cause stickiness of the material being sewn, poor lubricity, and poor surface wear resistance, and it is easy to be scratched by metal parts such as scissors, which will affect the sewing operation. In addition, all sewing machines now need lubricating oil. If the seal is not good, the lubricating oil in the sewing machine will leak and contaminate the sewn clothes. Contents of the invention [0003] The purpose of the present invention is to provide a kind of surface tre...
