2results about How to "Eliminate pitting" patented technology

This invention discloses a glass heating and forming equipment, relating to the field of glass hot bending forming technology. It includes a furnace frame, a furnace cavity, a placement platform, and a lifting system. The placement platform is equipped with a solid mold and a horizontally retractable support frame. The lifting system drives the placement platform to rise and close with the furnace cavity to form a closed heating chamber. When the support frame retracts, a linkage brush rod mechanism lifts the edge of the workpiece upwards, eliminating local concave corner defects. A partition glass is installed inside the solid mold to prevent direct contact between the workpiece and the mold, which could cause pitting and optical distortion. The placement platform can move horizontally and descend rapidly, utilizing gravity for secondary forming to improve the fit of curved surfaces. This equipment solves problems such as insufficient spherical and edge forming during the self-weight forming of bus windshields, optical distortion caused by long heating times, and low efficiency of manual edge pressing. It shortens the heating time, reduces optical defects, and improves the yield and product stability.
