Hot bending machine applying precise electric air cylinder

The invention discloses a hot bending machine applying a precise electric air cylinder, and relates to the technical field of hot bending machines, the hot bending machine comprises a machine box and a glass mold, the surface of the machine box is sequentially provided with a preheating assembly, a forming assembly and an annealing assembly from left to right, and a first upper mold is arranged above a first lower mold; a first heating plate is arranged in the first upper mold and the first lower mold, the glass mold is arranged between the first lower mold and the first upper mold, a circulating pump is arranged at the bottom of the water tank, and the annealing assembly and the forming assembly are consistent in structure. According to the hot bending machine applying the precise electric air cylinder, outside normal-temperature air is input into the water tank through the air injection pipe, the normal-temperature air penetrates through cooling liquid to be cooled and then is sprayed out towards the surfac
