A self-opening and closing monitoring operation three-chamber vacuum furnace

Abstract

The invention relates to an automatic opening and closing three-chamber vacuum furnace capable of monitoring operation, belonging to the technical field of vacuum furnaces. The three-chamber vacuum furnace comprises a cooling chamber, a heating chamber, a preparation chamber, vacuumizing mechanisms, an operation monitoring system and an automatic opening and closing mechanism, wherein the two sides of the heating chamber are respectively connected with the preparation chamber and the cooling chamber via chamber separation walls; insulation doors are arranged on the chamber separation walls; the cooling chamber comprises a gas quenching chamber and an oil quenching chamber; meanwhile, a filled gas quick cooling mechanism is arranged at the upper part of the gas quenching chamber; an oil quenching tank with a stirrer is arranged at the lower part of the oil quenching chamber; a gas convective circulation mechanism is arranged on the heating chamber; both the heating chamber and the insulation doors are provided with insulation layers, vacuum layers and stainless steel shells from the interior of the heating chamber to the exterior in sequence. The three-chamber vacuum furnace not only is safe in oil quenching and uniform in material heating but also has good insulation effects and high product quality, can save energy and automatically open the furnace door, and simultaneously has high processing efficiency.

Description

technical field [0001] The invention relates to a self-opening and closing monitoring operation three-chamber vacuum furnace, which belongs to the technical field of vacuum furnaces. Background technique [0002] At present, the existing vacuum furnace includes a cooling chamber and a heating chamber, and the cooling chamber and the heating chamber are separated by a partition wall; a gas quenching chamber and an oil quenching chamber are arranged inside the cooling chamber, and the gas quenching chamber is provided with an air-filled quick-cooling mechanism. source, while the oil quenching chamber performs oil quenching through the oil quenching tank. The inside of the heating chamber includes a heating chamber platform and a material frame. The material frame is placed on the heating chamber platform. At the same time, one or more heating tubes are evenly arranged in the heating chamber along the circumferential direction, and a vacuum mechanism is arranged outside the hea...

AI Technical Summary

Problems solved by technology

[0003] 1. During oil quenching, because the processed materials are put into the oil quenching oil tank, the oil surface is heated unevenly and the oil splashes, so accidents are prone to occur

[0004] 2. The inside of the heating chamber is statically heated by the heating tube, so it is easy to cause the material to be heated unevenly, and a good processing effect cannot be achieved.

[0005] 3. The heat insulation effect of the furnace wall of the heating chamber of this design is not good, and the temperature between the cooling chamber and the heating chamber cannot achieve good heat insulation, so the heat dissipation is serious and the energy consumption is high

[0006] 4. The vacuum furnace of this design needs to open the heating chamber when the material is heated and processed. Therefore, every time the material is processed, the heating chamber must be evacuated and heated again, which wastes a lot of energy, which is uneconomical and expensive. Environmental friendly

[0007] 5. When processing materials, this kind of heating furnace can only be processed manually, so its labor cost is high. At the same time, due to the limitation of workers' skills, the various processes cannot be well connected during processing, resulting in processing There are many defective products after the material

[0008] 6. Since the method of opening the furnace body of this design vacuum furnace is manual opening, when the furnace body needs to be opened, because the furnace door is heavy, it cannot be easily opened, so it is very inconvenient
