AI Technical Summary
Technical Problem
The vacuum furnace door does not close tightly and the locking mechanism is not reliable enough, which leads to a decrease in vacuum level and affects the heating effect.
Method used
A vacuum heating furnace was designed, which consists of a furnace body, a vacuum system, and a sealed door. The sealing of the door is ensured by hinges, mechanical locks, and a lifting mechanism. The vacuum environment inside the furnace is maintained by a vacuum pump system. The heating status is monitored through an observation window, and the heating parameters are set on a control panel.
Benefits of technology
It improves the stability of vacuum during the heating process, avoids workpiece oxidation and bubble generation, and ensures the stability and consistency of heating effect.

Abstract
This utility model relates to a vacuum heating furnace, including a furnace body, a vacuum system, and a sealed door. The furnace body is a shell with a completely open front end. Heating wires are installed inside the side walls of the furnace body. The vacuum system is spaced out on one side of the furnace body and is connected to the interior of the furnace body. Multiple hinges are evenly spaced from left to right on the top front side of the furnace body. One end of each hinge is fixedly installed on the top of the furnace body, and the other end is fixedly connected to the top of the sealed door. The hinges are used to hinge the sealed door to the sealed door. Multiple mechanical locks are installed at the bottom of the sealed door. By adopting the above technical solution, the workpiece to be heated is placed in the furnace body for heating. The vacuum system creates a vacuum environment, which makes the workpiece less prone to oxidation during the heating process and improves the heating effect. The locking mechanism ensures the sealing effect inside the furnace body, driving the rear part of the sealed door to be firmly attached to the surface of the furnace body, preventing the sealed door from affecting the heating effect due to air leakage.
