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 part of the body is set as a cylindrical structure 2, the middle is set as an external hexagonal structure 3, and the bottom is set as an external thread structure 4. The top of the main body is set as a semicircular structure 1, and the middle of the bottom of the main body is provided with a circular groove 5. The heat treatment process is characterized by immersing in a suitable quenching medium after heating to austenitization and cooling at a relatively fast speed. .
[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 cooling capacity should be selected, and distortion and quenching cracking should also be prevented.
[0012] The ...

The invention discloses an industrial sewing machine semi-circular connector and a heat treatment technology thereof. The industrial sewing machine semi-circular connector comprises a main body and the heat treatment technology comprises a heat treatment process, the upper part of the main body is arranged into a cylindrical structure, the middle of the main body is arranged into an external hexagonal structure, the bottom of the main body is arranged into an external thread structure, the top of the main body is arranged into a semi-circular structure, and a round groove is formed in the middle of the bottom of the main body. The heat treatment technology is characterized in that after being heated to austenization, the connector is immersed in a proper quenching medium and cooled at a high speed. The industrial sewing machine semi-circular connector has tensile strength which is high enough to resist elongation, breakage, slipping and wear, has relatively high fatigue resistance and impact toughness to resist fatigue and impact fracture, and can be well applied to an industrial sewing machine.
Description
technical field [0001] The invention relates to a mechanical product, in particular to a semicircular joint of an industrial sewing machine and a heat treatment process thereof. Background technique [0002] Some industrial sewing machine semi-circular joints 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 a semicircular joint of an industrial sewing machine and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that some existing semicircular joints of industrial sewing machines 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 i...
