Description
technical field [0001] The invention relates to the field of glass processing, in particular to a 3D glass hot bending machine, and also to a 3D glass forming method implemented by using the 3D glass hot bending machine. Background technique [0002] In related technologies, the hot bending of 3D glass mainly adopts the concave-convex mold hot pressing method, and both surfaces of the glass are strongly pressed by the upper and lower molds during the forming process. Therefore, if the surface roughness of the upper and lower molds is high, the mold particles are large, or the surface of the mold is defective, it is easy to transfer the defect to the glass surface, forming pitting, hot orange peel and other defects. Moreover, 3D glass hot bending has the defects of poor hot bending surface quality and slow hot bending speed. Contents of the invention [0003] The object of the present invention is to provide a 3D glass hot bending machine and a 3D glass forming method impl...
