This utility model discloses a waste heat quenching device for wear plates in railway freight car bogie grooves, belonging to the field of wear plate processing technology. The device includes a guide frame, a drive box installed below the guide frame, an electric cylinder installed on one side of the drive box, a quenching box installed on one side of the guide frame, a pushing plate inside the quenching box, a swing arm installed on one side of the quenching box, and a cooling oil heat exchanger between the heat exchange box and the quenching box. This utility model solves the problems of existing quenching devices having a simple structure, poor heat exchange effect, and poor positioning effect in actual use. This utility model uses quenching oil inside the quenching box for cooling, while simultaneously pushing the wear plate of the railway freight car bogie groove to move and cool. After cooling, the swing arm pushes the wear plate into the guide groove for rapid waste heat quenching.
