Problems solved by technology
However, if the furnace door falls at the same speed, it will cause the impact of the furnace door on the furnace body, resulting in frequent failure of the furnace door closing, which will cause the furnace door to close for too long, and a large amount of hot gas in the furnace will be emitted during this period, affecting the workpiece from the heating state to the furnace. The transfer time between quenching media, which in turn affects the processing quality of the entire workpiece

The invention provides a furnace door closing technology of a thermal-treatment multi-purpose furnace. The furnace door closing technology of the thermal-treatment multi-purpose furnace comprises a furnace body, a furnace door, a motor, a motor brake, a time-delay relay, a chain, a rectangular furnace opening, a lower limit piece, a furnace door track, quenching mediums and a workpiece. The furnace body is in a horizontal cylindrical shape, and the side surface of the furnace body is provided with the rectangular opening; the furnace door track is fixed on the vertical edge of the rectangular opening; the furnace door is fixed onto the furnace body through the furnace door track; the motor brake is fixed beside the furnace door track; the time-delay relay is connected with motor brake; the motor is fixed at the top of the furnace body and connected with the furnace door. The furnace door closing technology of the thermal-treatment multi-purpose furnace is reasonable in structure and reliable in connection; by controlling braking of the motor through the time-delay relay, so that the closing time of the furnace door can be greatly reduced, the closing reliability of the furnace door can be greatly improved, the time for conveying the workpiece from a heating chamber to the quenching mediums can be shortened, and the carburized quenching quality can be improved.
Description
technical field [0001] The invention relates to the field of furnace doors of heat treatment equipment, in particular to the door control technology for multi-purpose furnaces of heat treatment equipment. Background technique [0002] At present, the middle door of the multi-purpose furnace of the existing heat treatment equipment is controlled by a motor, and the furnace door is raised and lowered at the same speed. This method changes the previous manual operation method and ensures the safety of the operators. However, if the furnace door falls at the same speed, it will cause the impact of the furnace door on the furnace body, resulting in frequent failure of the furnace door closing, which will cause the furnace door to close for too long, and a large amount of hot gas in the furnace will be emitted during this period, affecting the workpiece from the heating state to the furnace. The transfer time between quenching media, which in turn affects the processing quality of...
