[0046] Working principle of the present invention: According to the product to be processed, a piece of raw crystal glass in block or column shape is placed on the driving turntable 22 controlled by the stepping motor 21 at the loading station by manual or robotic arm. An installation fixture 3 is installed at each station of the driving turntable 22, and there is a base heating plate 31 below each installation fixture 3. After the loading is completed, the stepping motor 21 rotates by an angle, and the crystal glass at the loading station moves to the preheating station. The preheating plate 42 at the preheating station descends to heat above the crystal glass, and at the same time, the base heating plate 31 below the installation fixture 3 heats up to heat below the crystal glass. The upper and lower heating plates heat the crystal glass together for preheating and temperature rise. The preheating station can be set to one or more. While preheating, the loading of the next piece of raw crystal glass is completed at the loading station, and the unloading of the finished crystal parts is completed at the unloading station. Thereafter, each time the stepping motor 21 runs once, the loading and unloading operations are performed once, and this cycle continues.

[0047] After the preheating is completed, the stepping motor 21 rotates by an angle, and the crystal glass at the preheating station moves to the primary forming station. The second telescopic cylinder 51 above the primary forming station descends, driving the first upper mold 52 to perform primary forming on the crystal glass, and the first heating plate 53 heats the first upper mold 52. After the primary forming is completed, the second telescopic cylinder 51 rises, and the stepping motor 21 rotates by an angle, and the crystal glass at the primary forming station moves to the secondary heating station.

[0048] The secondary heating station performs secondary heating on the crystal glass. The heating flame row 72 can quickly raise the temperature of the surface of the crystal glass, making the surface of the crystal glass reach the molten state and improving the surface finish of the crystal glass. After the secondary heating is completed, the stepping motor 21 rotates by an angle, and the crystal glass at the secondary heating station moves to the secondary forming station. The forming principle of the secondary forming station is the same as that of the primary forming station. For products with low requirements, the secondary heating station and the secondary forming station can be cancelled.

[0049] After the forming is completed, the stepping motor 21 rotates by an angle, and the crystal glass at the secondary forming station moves to the slow cooling station. The base heating plate 31 below the installation fixture 3 cools down the crystal parts. For the crystal parts that deform during the cooling process, the third upper mold 62 driven by the fourth telescopic cylinder 61 above the slow cooling station descends to perform pressure holding and cooling on the crystal parts to control the deformation of the crystal parts during the cooling process.

[0050] After the slow cooling is completed, the stepping motor 21 rotates by an angle, and the crystal parts at the slow cooling station move to the unloading station. At the unloading station, the crystal parts are unloaded by manual or robotic arm. The unloading station and the loading station can be combined into one station.

[0051] After the unloading is completed, the stepping motor 21 rotates by an angle, and the unloading station moves to the loading station to perform the loading of the raw crystal glass, and this cycle continues.
