Novel vacuum furnace automatic revolving door

Abstract

The invention discloses a novel vacuum furnace automatic revolving door which comprises a furnace door, a furnace door cantilever, a furnace door rotating shaft, gear motors and a control system, wherein the furnace door, the furnace door cantilever, the furnace door rotating shaft, the gear motors and the control system are mounted on a furnace body. The control system comprises a central controller and a servo controller, one end of the furnace door cantilever is fixedly connected with the furnace door, and the other end of the furnace door cantilever is fixedly connected with the furnace door rotating shaft in a rotating mode. The furnace door rotating shaft is connected with the gear motors, and the gear motors drive the furnace door rotating shaft to rotate along the ends connected with the gear motors. The servo controller is connected with the gear motors, the servo controller is connected with the central controller, and the central controller controls the gear motors through the servo controller to drive the furnace door rotating shaft to slowly rotate at the initial stage and the final stage so as to drive the furnace door to be slowly opened and closed. The novel vacuum furnace automatic revolving door can be automatically opened, and opening or closing safety and stability of the furnace door can be guaranteed.

Description

technical field [0001] The invention belongs to the field of vacuum furnaces, and more specifically relates to a novel automatic revolving door of a vacuum furnace. Background technique [0002] The consistent door opening method of vacuum furnace is a research topic of vacuum furnace equipment. Different from general heat treatment equipment, the furnace door of the vacuum furnace must meet both the vacuum requirement and the pressure requirement, which adds difficulty to the process, so the manual door opening method has been adopted at home and abroad for a long time. With the rapid development of the world, society has higher and higher requirements for heat treatment equipment, and unmanned chemical plants have become a reality. [0003] The furnace door of the vacuum furnace involves the opening method of the upper and lower cylinders and the opening method of the left and right cylinders on the basis of manual door opening. Although this door opening method realizes...

AI Technical Summary

Problems solved by technology

Although this door opening method realizes some automatic door opening work, it has its own defects: (1) The cylinder is driven by gas, and the force acting on it will be different each time due to factors such as gas pressure changes. Accuracy and stability can not achieve the best

(3) Opening the door up and down and opening the door left and right will increase the volume of the equipment, or increase the height of the up and down, or increase the width of the left and right, which is a limitation for factories with limited space
