Abstract

The utility model discloses a heat treatment device for a bearing roller, which relates to the technical field of bearing roller processing and comprises a cylinder body, a support column fixedly connected to the bottom of the cylinder body, a heat insulation sealing cover hinged to one side of the cylinder body, a material containing mesh cylinder rotatably mounted in the cylinder body, and a heating mechanism arranged between the material containing mesh cylinder and the cylinder body. A spiral cooling pipe is arranged in the cylinder wall of the cylinder body, and the water outlet end of the spiral cooling pipe is fixedly connected with a backflow pipe. Diversion pipes are arranged on the upper portion and the lower portion of the material containing net cylinder and evenly spray out hot air to conduct heat treatment on the bearing rollers in the material containing net cylinder, and the bearing rollers can be evenly heated; in addition, the spiral cooling pipe is arranged in the barrel, cooling water is introduced into the spiral cooling pipe for heat exchange, the cooling efficiency of the barrel after heat treatment is improved, the water cooling mechanism drives the exhaust assembly to work, the exhaust mechanism can rapidly exhaust hot air in the barrel, the cooling efficiency is improved, and therefore the overall treatment efficiency can be improved.
