Heating furnace door device with stable and rapid opening and closing functions

Abstract

The invention discloses a heating furnace door device with stable and rapid opening and closing functions. The heating furnace door device comprises a main power system, a furnace body, power transmission systems, a furnace door and an automatic furnace door locking system. The main power system is installed on a rear side base of the furnace body through bolts. The power transmission systems areinstalled at the left side and the right side of the furnace body through bolts. The bottom of the furnace door is installed at a furnace opening at the front end of the furnace body through a hinge,and the left and right sides are connected with the power transmission systems through bolts. The automatic furnace door locking system is installed at the lower side of the furnace opening at the front end of the furnace body through bolts. Furthermore, the device is simple in structure and convenient to operate, and the furnace door is opened and closed stably. In addition, due to the anti-collision and closing self-locking functions of the furnace door, the closing degree of the furnace door and the heating effect in a furnace can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a heating furnace door device with stable and fast opening and closing functions. Background technique [0002] With the development of thermal processing technology and the continuous improvement of product quality requirements, heating furnace and furnace door are indispensable devices in the thermal forming process, and their structure and performance have received more and more attention. Since the furnace door is generally heavy and needs to be opened and closed frequently, the traditional manual operation is time-consuming and labor-intensive. At the same time, the opening and closing process of the furnace door will drive the outside gas into the furnace body, which will have a great impact on the thermal process environment inside the furnace body, and then affect the quality of the processed sample. For this reason, there have been patent numbers "CN201820373674.X", "CN2...

AI Technical Summary

Problems solved by technology

[0003] 1) In the furnace door drive system, the mechanical structure is complex and the force load is large, and the reliability is not high

[0004] Due to the high requirements for the heating environment inside the furnace body during the thermal process, in order to achieve the effect of heat preservation and heat insulation on the furnace door, it is often designed to be relatively heavy, and the above-mentioned patents are directly connected by the mechanical structure of multiple connecting rods. Drive the furnace door to move. Obviously, the load on the connecting rod is relatively large. After long-term work, the connecting rod wears more seriously and is prone to failures such as fatigue damage.

At the same time, due to the large number of connecting rods, any failure of any part will cause the opening and closing of the furnace door to fail to complete normally, and the overall reliability is not high.

[0005] 2) The opening and closing speed of the furnace door cannot be adjusted according to the different processing test pieces or processing technology

However, the design of the motor control part is relatively simple, and the speed of the furnace door opening and closing cannot be changed according to the different processing specimens or processing techniques, and thus the gas entering the furnace body from the external environment cannot be effectively controlled.

[0007] 3) The furnace door has no anti-collision and closing self-locking functions, and the degree of closure and heat preservation effect of the furnace door cannot be effectively guaranteed

In the above-mentioned patents, the control of the working state of the furnace door is realized through the connecting rod. When the furnace door is close to the furnace body, due to the certain inertia of motion, collision between the furnace body and the furnace door will inevitably occur; To prevent collisions, reduce the closing speed of the furnace door in advance, and the furnace door may not be closed tightly

At the same time, when the electric drive system completes the closing action of the furnace door, there is no self-locking function, and it cannot be guaranteed that it will always be in a tight state
