Cold heading forming wear-resistant sliding block shaft

The utility model discloses a cold heading forming wear-resisting sliding block shaft, relates to the technical field of transmission parts for fuel oil internal combustion engines, and aims to solve the problems that in the current market, a whole fuel oil internal combustion engine crankshaft is generally subjected to heat treatment to a certain hardness, then high-frequency quenching is carried out on a part with high local requirement, and when local wear or other quality problems occur, the service life of the crankshaft is prolonged. And the whole part is directly scrapped, so that great waste is caused. A sliding block head body is arranged at the upper end of the wear-resisting sliding block shaft, a knurling matching shaft body is arranged in the middle of the lower end of the sliding block head body, a guide end is arranged below the knurling matching shaft body, and a sliding working arc table is arranged in the middle of the upper end of the sliding block head body. Arc bosses are symmetrically ar
