It is mainly composed of alloys and generally has good anti-oxidation, corrosion resistance, high temperature resistance and other properties. It can be used in extremely harsh environments and is mostly used in special industries. Heat treatment equipment is required for the processing and production of special steel. Among the heat treatment equipment, vacuum heat treatment equipment refers to a heat treatment process that is carried out entirely or partially under a vacuum state, which greatly improves the quality of heat treatment.

[0003] The Chinese patent with the relevant patent publication number CN220012723U discloses a vacuum heat treatment device, which has the advantages that when the transmission shaft rotates, the rotating shaft is driven to rotate through the docking port, and the transmission gear is driven to rotate by the gear ring, so that the workpiece can rotate while revolving, so that the workpiece rotates and heats in the vacuum furnace, making the temperature increase more uniform.

Not only are the operation steps cumbersome and inefficient, but the furnace port of the heating furnace is always in an open state during the process of lifting the workpiece, which not only causes a large amount of heat in the furnace to spray upward and dissipate, but also poses a great safety hazard to the staff. For this reason, we propose a vacuum heat treatment device. Utility Model Content

The rotation of the threaded rod 3 can lift the vacuum furnace 4 under the action of the side block 5, which is convenient for the placement of special steel. After the placement is completed, the motor 6 is reversed to reset the vacuum furnace 4. When discharging, the discharge chute can be blocked under the action of the insulation board 11, thereby achieving the purpose of preventing heat discharge.

[0028] In another embodiment, if Figure 3 As shown, a vertical rod 10 is fixedly connected to the top of the material seat 12 , and the vertical rod 10 is fixedly connected to the bottom of the insulation board 11 .

[0029] The heat insulation board 11 is supported under the action of the vertical rod 10 to ensure that the heat insulation board 11 is located above the material seat 12 and blocks the discharge chute when discharging or taking out materials.

[0032] In another embodiment, if Figure 3 As shown, a sealing ring 13 is arranged on the outer side of the material seat 12 , and the outer side of the sealing ring 13 is tightly fitted with the inner side of the feed groove 9 .
