Bolt annealing device

The bolt annealing device comprises a furnace body, a feeding mechanism and a discharging mechanism, a feeding port is formed in the front end of the furnace body, the feeding mechanism comprises a sliding rail, foot pads, a feeding plate, a rotating disc and an inserting rod, the sliding rail is connected to the bottom end of the interior of the furnace body through bolts, the front end of the sliding rail penetrates through the feeding port, and the foot pads are arranged on the feeding plate. The bottom of the front end of the sliding rail is connected with a plurality of foot pads through bolts. According to the utility model, the screw rod can be vertically placed on the discharging mechanism, the discharging mechanism is driven to rotate through the turntable, and then materials are driven to move circularly, and the circular motion of the materials and the rotation of the whole discharging mechanism drive air flow in the furnace body to flow, so that the annealing quantity is increased under the condit
