Technical Field
[0001] The utility model relates to the technical field of material heat treatment, in particular to a high-efficiency convection stirring tempering vacuum furnace. Background Art
[0002] Tempering vacuum furnace is a kind of equipment used for heat treatment of materials. It combines the advantages of vacuum technology and heat treatment technology, and can perform tempering heat treatment in vacuum or protective atmosphere, which helps to improve the tempering quality of workpieces by removing oxygen and other gases and reducing the possibility of oxidation and corrosion. The optimized furnace structure and convection heating device ensure the temperature uniformity at low temperature and guarantee the heat treatment effect of workpieces. Tempering vacuum furnace can be single-chamber, internal heating type, and can be designed into horizontal or vertical structure according to needs to meet different industrial application requirements. It is suitable for tempering treatment of various materials, such as high-speed steel, tool steel, alloy structural steel, stainless steel, etc., as well as annealing and aging treatment of non-ferrous metals.
[0003] During the operation of the tempering vacuum furnace, attention should be paid to details such as nitrogen should not be used as a cooling gas to treat titanium alloys, and special vacuum quenching oil should be used when the workpiece is quenched under a vacuum state. Stirring is usually used to assist in the tempering process. When the traditional stirring method uses a stirring blade to stir, only the part close to the stirring blade can be continuously pushed. The part adhering to the surface of the furnace body is often unable to rotate because the furnace body makes the stirring assistance inefficient. Therefore, a high-efficiency convection stirring tempering vacuum furnace is proposed. Convection stirring is achieved by simultaneously rotating the furnace body and the stirring blades in the furnace to improve the stirring efficiency. Utility Model Content

[0014] Compared with the prior art, the utility model provides a high-efficiency convection stirring tempering vacuum furnace, which has the following beneficial effects:
[0015] 1. The high-efficiency convection stirring tempering vacuum furnace uses a vacuum pipe to add materials to the inside of the feeding seat through a sealing cover.

[0037] The driving motor 51 is provided to provide power, and the transmission wheel 52 transmits the power to the transmission belt 53 .
[0038] In this embodiment, the output shaft of the driving motor 51 transversely penetrates the side wall of the support seat 46 to the inside and is rotatably connected to the support seat 46.

[0040] The working principle of the above embodiment is:
[0041] By using a vacuum pipe, the material is added to the inside of the feeding seat 21 through the sealing cover 23.

The rotation of the spiral stirring blade 33 drives the material to be stirred inside the furnace body 31 while continuously pushing the material to move horizontally in the furnace body 31, thereby solving the problem of the traditional stirring method that the stirring blade can only continuously push the part close to the stirring blade, resulting in low stirring efficiency.
