Figure 1 and Figure 2 As shown, the hot pressing device 100 for the sheet 200 includes a hot pressing plate 11, a plurality of first cylinder groups 12, and a plurality of first support assemblies 13. The hot pressing plate 11 is used to perform hot pressing forming on the sheet 200 under control. The plurality of first cylinder groups 12 are located on the top of the hot pressing plate 11, and the plurality of first cylinder groups 12 are respectively arranged near the two side edges of the hot pressing plate 11, and each first cylinder group 12 includes a plurality of first cylinders 121. Each first support assembly 13 is connected between the hot pressing plate 11 and a first cylinder group 12, and each first support assembly 13 is connected to the plurality of first cylinders 121 of the corresponding first cylinder group 12. The first cylinder group 12 is configured to controllably drive the corresponding first support assembly 13 and the hot pressing plate 11 to move vertically, thereby hot pressing forming the sheet 200. Here, the connection method between the first support assembly 13 and the hot pressing plate 11 can be fixed by bolts or welding. In this embodiment, a plurality of first oil cylinders 121 are connected by a first support assembly 12. Compared with the technical solution of connecting a first support assembly 12 to a first oil cylinder 121 in the prior art, the hot pressing plate 11 can be subjected to uniform force, thereby preventing the edges on both sides of the hot pressing plate 11 from deforming during the hot pressing process.

[0042] Figure 3 yes Figure 1 A schematic top view of the first support assembly 13 of the hot pressing device 100 for the plate 200 is shown in FIG. Figure 3 As shown, the first oil cylinder 121 includes a chuck 1211, and the first support assembly 13 includes a first base plate 131 and at least one oil baffle plate 132 installed on the first base plate 131. Each oil baffle plate 132 corresponds to a first oil cylinder 121, and the oil baffle plate 132 is arranged around the circumference of the chuck 1211 of the corresponding first oil cylinder 121. The arrangement of the chuck 1211 improves the stability of the first oil cylinder 121. The oil baffle plate 132 is located below the first oil cylinder 121, and is used to block the leaked oil of the first oil cylinder 121 to prevent the leaked oil from affecting the hot pressing. In some preferred embodiments, each first oil cylinder group 12 includes two first oil cylinders 121, and two oil baffle plates 132 are installed on the first base plate 131 of each first support assembly 13, and the oil baffle plate 132 connects the two first oil cylinders 121 of the corresponding first oil cylinder group 12.
