DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

The hydraulic lifting plate 312 is installed on the base 1. The initial position of the hydraulic lifting plate 312 is between the vacuum tank 21 and the base 1. When picking up or putting down materials, the hydraulic lifting plate 312 moves to the side of the opening of the vacuum tank 21. After the vacuum tank 21 is opened, the hydraulic lifting plate 312 moves to the bottom of the material to lift it, so that the hydraulic lifting plate 312 lifts the material to move it.

[0024] When using this invention: Before vacuum heating treatment, the hydraulic lifting plate 312 is activated and moved to the side of the vacuum tank 21. The hydraulic lifting plate 312 is then moved horizontally to the bottom of the material tray on the material cart.

After the vacuum tank 21 has vacuum-heated the material in the tray, the hydraulic lifting plate 312 moves back into the vacuum tank 21 and then puts the material tray back onto the material cart. This avoids direct contact between employees and the vacuum-heated material and the material tray. Furthermore, the slow cooling rate of the material due to the vacuum environment inside the furnace after vacuum heating treatment prevents employees from being burned by uncooled parts when moving vacuum-heated parts, reducing safety risks and improving the safety of equipment use.
