The invention discloses an electric heating furnace for hot stamping. The electric heating furnace comprises a high-temperature-resistant conveying belt, a bearing frame, a servo motor and a temperature sensor, an assembly base plate is arranged at the bottom end of the bearing frame, the high-temperature-resistant conveying belt is fixed to the top end of the bearing frame, a controller is arranged at the end, below the high-temperature-resistant conveying belt, in the bearing frame, the servo motor is arranged at the other end, below the high-temperature-resistant conveying belt, in the bearing frame, and a heating furnace body welded to the bearing frame is arranged on the outer side of the high-temperature-resistant conveying belt in a covering mode. According to the electric heating furnace, by installing a fixing base, the heating furnace body, a reserved sliding strip and a reserved sliding groove, the structure of the device is optimized, during use, a user can assemble or disassemble the fixing base and the heating furnace body by utilizing a sliding connection structure formed by the reserved sliding strip and the reserved sliding groove under the cooperation of the locking and fixing effects of a locking sheet and a locking bolt, then an air curtain machine can be disassembled, assembled and maintained, and therefore the functionality of the device is enhanced.
