Abstract

The invention discloses an automobile chassis connecting piece and a thermal processing technology thereof. The automobile chassis connecting piece comprises a body. The thermal processing technology comprises a thermal processing process. The upper portion of the body is of a cylindrical structure set as a first cylindrical structure. Key grooves are formed in the front side and the back side of the first cylindrical structure respectively and include the front key groove and the back key groove. The middle of the body is of a cylindrical structure and is set as a second cylindrical structure. The lower portion of the body is of an outer thread structure. The thermal processing technology is characterized in that after austenitizing is achieved through heating, the automobile chassis connecting piece is immersed into an appropriate quenching medium to be rapidly cooled. The automobile chassis connecting piece has high enough tensile strength 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 an automobile chassis.

Description

A kind of connecting piece for automobile chassis and heat treatment process thereof
Technical field
The present invention relates to a kind of engineering goods, specifically a kind of connecting piece for automobile chassis and heat treatment process thereof.
Background technique
Some connecting piece for automobile chassis 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 automobile chassis.
Summary of the invention
The invention provides a kind of connecting piece for automobile chassis and heat treatment process thereof.
The object of the invention is to solve more existing connecting piece for automobile chassis, there is no sufficiently high tensile strength, elongation cannot be resisted, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, well can not apply to the problem in automobile chassis.
The technical solution adopted for the present invention to solve the technical problems is: a kind of connecting piece for automobile chassis and heat treatment process thereof, comprise body and heat treated process, described body is set to cylindrical structure above it, be set to the first cylindrical structure, before and after it, both sides are respectively provided with a keyway, be respectively front keyway and rear keyway, cylindrical structure is set to equally in the middle of described body, be set to the second cylindrical structure, external thread structure is set to below described body, its heat treatment process feature immerses after being heated to austenitizing in suitable quenching medium with speed cooling faster.
Described heat treatment process, when selective quenching medium, first should ensure enough cooling capacities, namely 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, slide fastener and wearing and tearing, and has higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in automobile chassis.
Accompanying drawing explanation
Fig. 1 is side 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, described body is set to cylindrical structure above it, be set to the first cylindrical structure 2, before and after it, both sides are respectively provided with a keyway, be respectively front keyway 1 and rear keyway 5, cylindrical structure is set to equally in the middle of described body, be set to the second cylindrical structure 3, be set to external thread structure 4 below described body, its heat treatment process feature immerses after being heated to austenitizing in suitable quenching medium with speed cooling faster.
Described heat treatment process, when selective quenching medium, first should ensure enough cooling capacities, namely 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, slide fastener and wearing and tearing, and has higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in automobile chassis.
