Abstract
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
The present invention relates to a kind of engineering goods, is a kind of industrial sewing machine oil circuit connective slot and thermal treatment process thereof specifically.
Background technology
Some industrial sewing machine oil circuit connective slots on existing market, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impelling strength also not high enough, cannot resisting fatigue and impact fracture, can not well apply in industrial sewing machine.
Summary of the invention
The invention provides a kind of industrial sewing machine oil circuit connective slot and thermal treatment process thereof.
The object of the invention is to solve more existing industrial sewing machine oil circuit connective slots, there is no sufficiently high tensile strength, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impelling strength also not high enough, cannot resisting fatigue and impact fracture, can not well apply to the problem in industrial sewing machine.
The technical solution adopted for the present invention to solve the technical problems is: a kind of industrial sewing machine oil circuit connective slot and thermal treatment process thereof, comprise body and heat treated process, its head of described body is made as spheroidal structure, its above and below is all made as cylindrical structure, be made as the first cylindrical structure and the second cylindrical structure, the second described cylindrical structure is provided with the connection piece of three outer-hexagonal shape structures, be respectively the first connection piece, the second connection piece and the 3rd connection piece, in the middle of described body, be provided with circular groove, its thermal treatment process feature is after being heated to austenitizing, to immerse in suitable quenchant so that speed is cooling faster.
Described thermal treatment process, when selective quenching medium, first should guarantee enough cooling poweies, selects the quenchant that cooling power is high, also should prevent distortion and hardening break.
The present invention has sufficiently high tensile strength, to resist elongation, breaks, and slide fastener and wearing and tearing, and have higher fatigue resistance and impelling strength, can resisting fatigue and impact fracture, can well apply in industrial sewing machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in the figure, the present invention includes body and heat treated process, its head of described body is made as spheroidal structure 1, its above and below is all made as cylindrical structure, be made as the first cylindrical structure 2 and the second cylindrical structure 7, the second described cylindrical structure 7 is provided with the connection piece of three outer-hexagonal shape structures, be respectively the first connection piece 3, the second connection piece 4 and the 3rd connection piece 5, in the middle of described body, be provided with circular groove 6, its thermal treatment process feature is after being heated to austenitizing, to immerse in suitable quenchant so that speed is cooling faster.
Described thermal treatment process, when selective quenching medium, first should guarantee enough cooling poweies, selects the quenchant that cooling power is high, also should prevent distortion and hardening break.
The present invention has sufficiently high tensile strength, to resist elongation, breaks, and slide fastener and wearing and tearing, and have higher fatigue resistance and impelling strength, can resisting fatigue and impact fracture, can well apply in industrial sewing machine.
