Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0011] As shown in the figure, the present invention includes a body and a heat treatment process. The top of the body is set as a cylindrical structure, which is set as a first cylindrical structure 1, and a groove 2 is arranged in the middle, and a groove 2 is arranged below the body. It is a cylindrical structure, which is set as the second cylindrical structure 3, and an annular circlip groove 4 is arranged below it. The heat treatment process is characterized by immersing it in a suitable quenching medium at a relatively fast speed after heating to austenitization. cool down.

[0012] When selecting the quenching medium for the heat treatment process, sufficient cooling capacity should be ensured first, that is, the quenching medium with high cooling capacity should be selected, and distortion and quenching cracking should also be prevented.

Abstract

The invention discloses an automobile chassis bolt and a thermal processing technology thereof. The automobile chassis bolt 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. A groove is formed in the middle of the first cylindrical structure. The lower portion of the body is of a cylindrical structure set as a second cylindrical structure. An annular snap spring groove is formed in the lower portion of the second cylindrical structure. The thermal processing technology is characterized in that after austenitizing is achieved through heating, the automobile chassis bolt is immersed into an appropriate quenching medium to be rapidly cooled. The automobile chassis bolt 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

technical field [0001] The invention relates to a mechanical product, in particular to an automobile chassis latch and a heat treatment process thereof. Background technique [0002] Some automobile chassis pins on the existing market cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and impact fracture, so they cannot be well used in automobile chassis middle. Contents of the invention [0003] The invention provides an automobile chassis bolt and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that some existing automobile chassis bolts do not have high enough tensile strength to resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and fatigue. Impact fracture, can not be well used in the car chassis. [0005] The technical scheme adopted by th...
