Abstract
The invention discloses an automotive body connecting pin and a heat treatment process thereof. The automotive body connecting pin comprises a body, and the heat treatment process includes heat treatment. The upper portion of the body is arranged as a cube-shaped structure, a round through hole is arranged in the top of the cube-shaped structure, the lower portion of the body is arranged as a cylindrical structure, and the bottom of the cylindrical structure is provided with a snap spring groove. The heat treatment process is characterized by including heating to austenitizing prior to soaking in an appropriate quenching medium for cooling at high speed. The automotive body connecting pin has high enough tensile strength so as to resist stretching, tensile failure, thread slipping and abrasion, has high fatigue resistance and impact toughness, can resist fatigue and impact fracture and can be well applied to automotive bodies.
Description
Technical field
The present invention relates to a kind of engineering goods, is a kind of automotive body connecting pin and heat treatment process thereof specifically.
Background technique
Some automotive body connecting pins on existing market, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, can not well apply in automotive body.
Summary of the invention
The invention provides a kind of automotive body connecting pin and heat treatment process thereof.
The object of the invention is to solve more existing automotive body connecting pins, there is no sufficiently high tensile strength, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, can not well apply to the problem in automotive body.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automotive body connecting pin and heat treatment process thereof, comprise body and heat treated process, its top of described body is made as square body structure, its top is provided with a circular through hole, described body its underpart is made as cylindrical structure, its bottom is provided with a jump-ring slot, and its heat treatment process feature is so that speed is cooling faster in being heated to immerse suitable quenching medium after austenitizing.
Described heat treatment process, in the time of selective quenching medium, first should ensure enough cooling capacities, selects the quenching medium 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 toughness, can resisting fatigue and impact fracture, can well apply in automotive body.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is plan view 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 square body structure 1, its top is provided with a circular through hole 2, described body its underpart is made as cylindrical structure 3, its bottom is provided with a jump-ring slot 4, and its heat treatment process feature is so that speed is cooling faster in being heated to immerse suitable quenching medium after austenitizing.
Described heat treatment process, in the time of selective quenching medium, first should ensure enough cooling capacities, selects the quenching medium 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 toughness, can resisting fatigue and impact fracture, can well apply in automotive body.
