Abstract

The invention discloses an automobile ball pin and a preparation method thereof. Specifically, the automobile ball pin consists of a rod body (1) and a cavity equipped ball head (2) disposed on the rod body (1), wherein the ball head (2) top is also equipped with a through-hole running through the cavity, and the side of one rod body (1) end far from the ball head (2) is also equipped with external thread. The preparation method includes: firstly conducting cold extrusion on a material to form a ball pin initial blank including a rod blank and an extension section disposed at the upper end of the rod blank, then performing cold extrusion on the extension section to form the through-hole equipped ball head far from the side of the rod blank, and finally processing external thread on the external surface of one rod blank end far from the ball head, thereby obtaining the automobile ball pin with a needed shape. Therefore, a hot forging process is avoided, the material utilization is enhanced, the energy consumption is reduced, substantial saving of materials is realized, and the prepared automobile ball pin still has very good strength effect.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of auto parts, in particular to an auto ball pin and a preparation method thereof. Background technique [0002] In automobile chassis parts, ball joint parts can be seen everywhere. For some parts that bear the weight of the vehicle body and are also responsible for steering functions, the quality of the ball joint (ball pin) is particularly critical; the material of the ball pin is generally 42CrMo4, and the ball pin blank is currently on the market. Mainly hot forging, the material utilization rate is not high, high energy consumption, and easy to produce axial cracks, the risk of missed detection by magnetic particle fluorescence flaw detection in the later stage is relatively high. With the increasingly serious energy crisis, people will pay more attention to the quality of the environment, coupled with the increasingly intensified market competition, prompting the production of fo...
