Abstract
The invention discloses a spindle fixing sleeve of an industrial sewing machine and a thermal treatment technique of the spindle fixing sleeve. The spindle fixing sleeve comprises a body and the thermal treatment technique. The body is of cylindrical structure with a cylindrical through hole, the upper side of the body is provided with an annular chamfer, and the lower side of the body is provided with an annular notch. The thermal treatment technique is characterized by heating the spindle fixing sleeve until austenitizing and soaking the spindle fixing sleeve into suitable quenching medium so as to be quickly cooled. The spindle fixing sleeve has the advantages of high enough tensile strength to resist to stretch, snap, slide and wear, high fatigue resistance and impact toughness and fatigue and impact breakage resistance, and can be well applied to the industrial sewing machine.
Description
Technical field
The present invention relates to a kind of engineering goods, is a kind of industrial sewing machine rotating shaft fixed cover and Technology for Heating Processing thereof specifically.
Background technology
Some industrial sewing machine rotating shaft fixed covers on existing market, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact flexibility 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 rotating shaft fixed cover and Technology for Heating Processing thereof.
The object of the invention is to solve more existing industrial sewing machine rotating shaft fixed covers, there is no sufficiently high tensile strength, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact flexibility 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 rotating shaft fixed cover and Technology for Heating Processing thereof, comprise body and heat treated process, described body is made as cylindrical structure, in the middle of it, be provided with tubular through hole, described body top is provided with an annular chamfering, below is provided with an annular notch, and its Technology for Heating Processing feature is so that speed is cooling faster in being heated to immerse suitable hardening media after austenitizing.
Described Technology for Heating Processing, in the time of selective quenching medium, first should ensure enough cooling capacities, selects the hardening media that cooling capacity 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 impact flexibility, can resisting fatigue and impact fracture, can well apply in industrial sewing machine.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in the figure, the present invention includes body 3 and heat treated process, described body 3 is made as cylindrical structure, in the middle of it, be provided with tubular through hole 1, described body 3 tops are provided with an annular chamfering 2, below is provided with an annular notch 4, and its Technology for Heating Processing feature is so that speed is cooling faster in being heated to immerse suitable hardening media after austenitizing.
Described Technology for Heating Processing, in the time of selective quenching medium, first should ensure enough cooling capacities, selects the hardening media that cooling capacity 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 impact flexibility, can resisting fatigue and impact fracture, can well apply in industrial sewing machine.
