Embodiment Construction
[0009] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0010] As shown in the figure, the present invention includes a body and a heat treatment process. The left side of the body is set as a cylindrical structure, which is set as the first cylindrical structure 1, and the middle is set as a frustum-shaped structure 2. The right side of the body is set as a cylindrical structure. The side is set as a cylindrical structure, and it is set as a second cylindrical structure 4. A circular through hole 5 is provided in the middle, and a circular groove 3 is provided in the middle of the bottom. The heat treatment process is characterized in that it is heated to After austenitizing, immerse in a suitable quenching medium to cool at a faster rate.
[0011] When selecting the quenching medium for the heat treatment process, sufficient cooling capacity should be ensured first, that is, the quenching medium with high coolin...

The invention discloses an industrial sewing machine oil circuit connecting member and a heat treatment process thereof. The industrial sewing machine oil circuit connecting member and the heat treatment process thereof comprise a body and a heat treatment process, wherein the left side of the body is of a cylindrical structure, which serves as a first cylindrical structure, the middle of the first cylindrical structure is of a truncated cone shaped structure, the right side of the body is of a cylindrical structure, which serves as a second cylindrical structure, a circular through hole is formed in the middle of the second cylindrical structure, and a circular groove is formed in the middle of the bottom of the second cylindrical structure; the heat treatment process is characterized by heating to the temperature of austenitization, and then, immersing into an appropriate quenching medium, so as to cool at a relatively high speed. The oil circuit connecting member has high-enough tensile strength, so as to resist stretching, stretch-breaking, thread slipping and wearing, has relatively high fatigue resistance and impact toughness, so as to resist fatigue and impact break, and can be excellently applied to an industrial sewing machine.
Description
technical field [0001] The invention relates to a mechanical product, in particular to an industrial sewing machine oil circuit connector and a heat treatment process thereof. Background technique [0002] Some industrial sewing machine oil circuit connectors on the existing market cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and impact fracture, so they cannot be used well in industrial sewing machines. Contents of the invention [0003] The invention provides an industrial sewing machine oil circuit connector and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that some existing industrial sewing machine oil circuit connectors do not have high enough tensile strength to resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to be Resistance to fatigue and impa...
