More preferably, the outer diameter of the front section is larger than that of the rear section, the diameter of the inner hole corresponding to the front section is larger than that of the inner hole corresponding to the rear section, and the wall thickness of the front section is equal to that of the rear section.
The wall thickness of anterior segment and back end equals, and like this, the intensity of guide pin bushing anterior segment and back end is the same, and the process arrangement of cold forging process is more convenient.
Further preferably, a tapered chamfer is arranged at one end, located on the step, of the small diameter of the inner hole, the angle of the tapered chamfer is 120 degrees, a tapered chamfer is arranged at the other end of the small diameter of the inner hole, and the angle of the tapered chamfer is 90 degrees. The step of hole sets up the chamfer, has when the part passes the hole, can not produce the phenomenon of scraping.
More preferably, the included angle of the conical surface of the middle section facing the front section is 120 °, and the included angle of the conical surface of the middle section facing the rear section is 30 °.
Further preferably, the length of the conical surface with an included angle of 30 ° is greater than the length of the conical surface with an included angle of 120 °.
Further preferably, a radial torus is formed between the conical surfaces of the rear section and the middle section.
The utility model has the beneficial effects that: the guide sleeve is formed by cold forging, after the cold forging, a cylindrical front section and a cylindrical rear section are formed at two ends of the guide sleeve, a hexagonal structure is formed in the middle section, the size of the middle section is the largest, and inner holes are formed simultaneously in the cold forging process, so that high smoothness is obtained, no machining trace exists on the surface of the cold forging, more complex grinding is not needed, the machining efficiency is high, and cutting waste is not generated; the axial both ends of middle section are the conical surface, can play the effect of direction like this when the assembly, make things convenient for guide pin bushing assembly.
