The self-opening / closing anti-corrosion operation monitoring three-chamber vacuum furnace provided by the invention has the advantages of safe oil quenching, uniform material heating, good heat insulation effect and high product quality and can save energy; meanwhile, the processing efficiency is high, the furnace door can be automatically opened / closed, and the corrosion of the vacuumizing mechanism can be avoided.

Description

technical field [0001] The invention relates to a self-opening and closing anti-corrosion 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 ...

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. When the existing vacuum furnace is vacuumed, a large amount of dust will be generated when the materials in the cooling chamber and heating chamber are heated or cooled, so when the vacuuming mechanism is vacuumed, the vacuuming mechanism is easy to corrode

[0009] 7. Since the method of opening the furnace body of the vacuum furnace of this design is manual opening, when the furnace body needs to be opened, the furnace door is heavy and cannot be opened easily, so it is very inconvenient
