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 top of the body is set as a conical structure 1, and the bottom of the body is set as a circular block, which is set as the first block 2. The bottom of the body is Set as a cylindrical structure 3, the bottom of the body is provided with a circular baffle, which is set as the second baffle 4, and the middle of the body is set as a hollow structure 5, and its heat treatment process is characterized in that it is heated to austenite After thawing, 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 cooling capacity should be selected, and distortion and quenching cracking should ...

The invention discloses an industrial sewing machine oil pump head connecting piece and a heat treatment technology of the industrial sewing machine oil pump head connecting piece. The industrial sewing machine oil pump head connecting piece comprises a body, the heat treatment technology comprises a heat treatment process, the upper portion of the body is of a conical structure, a round blocking piece is arranged on the lower portion of the body, that is, a first blocking piece is arranged on the lower portion of the body, the lower portion of the body is of a cylindrical structure, a round blocking piece is arranged at the bottom of the body, that is, a second blocking piece is arranged at the bottom of the body, and the middle of the body is of a hollow structure. The heat treatment technology is characterized in that the connecting piece is heated to austenitizing, and then the connecting piece is immersed into appropriate quenching media to be cooled at the high speed. The industrial sewing machine oil pump head connecting piece has the high enough tensile strength so as to resist lengthening, tensile failure, thread slipping and abrasion, has the higher fatigue resistance and impact toughness so as to resist fatigue and impact fracture, and can be applied into an industrial sewing machine well.
Description
technical field [0001] The invention relates to a mechanical product, in particular to an industrial sewing machine oil pump head connector and a heat treatment process thereof. Background technique [0002] Some industrial sewing machine oil pump head 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 well Used in industrial sewing machines. Contents of the invention [0003] The invention provides an industrial sewing machine oil pump head 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 pump head 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 prevent It can resist fat...
