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 upper and lower parts of the body are configured as cylindrical structures, which are respectively a first cylindrical structure 5 and a second cylindrical structure 1, wherein the first cylindrical structure The angle between the structure 5 and the second cylindrical structure 1 is 45°, and the top of the first cylindrical structure 5 is set as an external thread structure, which is set as an upper thread 6, and the second cylindrical structure The middle of 1 is set as an external hexagonal structure 4, the bottom of which is set as an external thread structure, and is set as a lower thread 3, and the middle of the body is set as a hollow structure 2. The heat treatment process is characterized by heating to austenitization Immerse in a suitable quenching...

Abstract
The invention discloses an industrial sewing machine oil pipe nozzle joint and its heat treatment process, including a body and a heat treatment process. The upper and lower sides of the body are both cylindrical structures, which are respectively the first cylindrical structure and the second cylindrical structure. structure, wherein the angle between the first cylindrical structure and the second cylindrical structure is 45°, the upper part of the first cylindrical structure is set as an external thread structure, which is set as an upper thread, and the second The middle of the cylindrical structure is set as an external hexagonal structure, the bottom of which is set as an external thread structure, which is set as a lower thread, and the middle of the body is set as a hollow structure. The heat treatment process is characterized by immersion in the Cool at a faster rate in a suitable quenching medium. The invention has high enough tensile strength to resist elongation, breaking, slipping and wear, and has high fatigue resistance and impact toughness, can resist fatigue and impact fracture, and can be well used in industrial sewing machines .
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...
