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 head of the body is set as a spherical structure 1, and its top and bottom are all set as a cylindrical structure, which is set as a first cylindrical structure 2 and a second cylindrical structure. Cylindrical structure 7, the second cylindrical structure 7 is provided with three connecting pieces of outer hexagonal structure, respectively the first connecting piece 3, the second connecting piece 4 and the third connecting piece 5, the body There is a circular groove 6 in the middle, and its 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 b...

The invention discloses an industrial sewing machine oil-way connecting groove and a heat treatment technology thereof. The industrial sewing machine oil-way connecting groove comprises a main body and the heat treatment technology comprises a heat treatment process, the head part of the main body is arranged into a spherical structure, both the upper part and the lower part of the main body are arranged into cylindrical structures, namely a first cylindrical structure and a second cylindrical structure, three connecting pieces, which are a first connecting piece, a second connecting piece and a third connecting piece and adopt external hexagonal structures, are arranged on the second cylindrical structure, and a round groove is formed in the middle of the main body. The heat treatment technology is characterized in that after being heated to austenization, the oil-way connecting groove is immersed in a proper quenching medium and cooled at a relatively high speed. The industrial sewing machine oil-way connecting groove 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 an industrial sewing machine oil passage connecting groove and a heat treatment process thereof. Background technique [0002] Some industrial sewing machine oil circuit connecting grooves 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 passage connecting groove 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 connection grooves 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...
