Abstract

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

A kind of industrial sewing machine semi-circular joint and thermal treatment process thereof
Technical field
The present invention relates to a kind of engineering goods, is a kind of industrial sewing machine semi-circular joint and thermal treatment process thereof specifically.
Background technology
Some industrial sewing machine semi-circular joints 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 semi-circular joint and thermal treatment process thereof.
The object of the invention is to solve more existing industrial sewing machine semi-circular joints, 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 semi-circular joint and thermal treatment process thereof, comprise body and heat treated process, its top of described body is made as cylindrical structure, in the middle of it, be made as outer-hexagonal shape structure, its bottom is made as outside screw type structure, described bodies top is made as semicircular structure, in the middle of described body bottom, 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 top of described body is made as cylindrical structure 2, in the middle of it, be made as outer-hexagonal shape structure 3, its bottom is made as outside screw type structure 4, described bodies top is made as semicircular structure 1, in the middle of described body bottom, is provided with circular groove 5, and 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.
