Abstract

The invention belongs to the technical field of sewing machine machining and relates to a sewing machine part, in particular to a sewing machine horizontal transmission shaft and a machining method thereof. The sewing machine horizontal transmission shaft is obtained by integrally forming an aluminum alloy base body with the surface provided with a nanohole and ceramic, and the aluminum alloy base body is composed of the following ingredients of, in percentage by mass, 2.2-4.2% of Mg, 1.2-2.0% of Si, 0.35-0.80% of Cr, 1.0-1.5% of C, 0.12-0.18% of Cu, 0.12-0.20% of Mn, 0.15-0.25% of Zn, 0.05-1.5% of Ni, 0.02-0.4% of B, 0.05-0.10% of Zr, 0.06-0.10% of Sc and the balance Al and inevitable impurities. The sewing machine horizontal transmission shaft is good in comprehensive performance and particularly has good wear resistance, mechanical performance and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of sewing machine processing, and relates to a sewing machine component, in particular to a sewing machine horizontal transmission shaft and a processing method thereof. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] The transmission part of the existing sewing machine is composed of components such as a frame, a hand crank or a motor. The frame is the pillar of the machine, supporting the platen and the pedals. During use, the operator steps on the pedals to drive the pulley through the crank The rotation of the chicken is driven by the belt to rotate the chicken head, and most of the hand c...
