Bent toughened glass forming equipment and method

Abstract

The invention discloses bent toughened glass forming equipment. The bent toughed glass forming equipment comprises a rack, an air grid system and a forming system, wherein the air grid system comprises a plurality of upper air grids and a plurality of lower air grids; the upper air grids are mounted on the upper portion of the rack through a hoisting mechanism; the lower air grids are mounted in the forming system on the lower portion of the rack; a gradual transition section is arranged on the inlet side of the forming system, so that a glass plate is gradually changed into an arc in the transverse direction, and the glass plate which has been gradually changed into the arc is fed into the forming system; the forming system comprises two longitudinal forming arc-changing mechanisms and aplurality of transverse forming arc-changing mechanisms arranged in the conveying direction of the glass plate; the longitudinal forming arc-changing mechanism longitudinally bends and forms the glassplate; and the transverse forming arc-changing mechanisms are connected with the longitudinal forming arc-changing mechanisms through lower support cross beams, and the glass plate is transversely bent and formed. The equipment and the forming method provided by the invention can be used for processing various bent toughened glass without manufacturing a special mold, and have the advantages of rapid and convenient forming adjustment, stability, reliability, difficulty in deformation and high production efficiency.

[0002] The construction field is one of the important application fields of toughened glass. In order to pursue the visual beauty and safety requirements, many building exterior walls are designed with spherical or curved glass-shaped structures. These spherical or curved glass-shaped structures need to be disassembled The hyperboloid or multi-curved curved tempered glass can only be produced, processed and installed by forming a piece of corresponding, smooth transition connection. This kind of hyperboloid or multi-curved curved tempered glass is easy to warp and deform during processing. The final hyperboloid curved tempered glass cannot be smoothly transitioned and connected during installation and connection, so it cannot be installed to form a spherical or curved glass shape that meets the requirements; in actual production, the production and processing of this hyperboloid or multi-curved curved tempered glass is difficult.

[0003] In order to ensure that the multi-curved curved tempered glass does not deform as much as possible during the molding process, it is usually necessary to design a special multi-curved glass tempered molding mold. Since the multi-curved curved tempered glass that constitutes the spherical or curved glass structure has many specifications, the production process Each type of multi-curved curved tempered glass needs to make special molds, resulting in a large number of special molds for production equipment, high manufacturing costs, poor versatility of special molds, and frequent replacement of special molds for installation and debugging during production and processing, resulting in long production auxiliary time , the production efficiency is low, so it is necessary to design an equipment that can produce multi-curved tempered glass without special molds, so as to improve production efficiency and reduce equipment cost. At present, there are also equipment that use flexible shafts to shape glass, but the transmission of the equipment The system is set at the end of the flexible shaft, and also includes the driving shaft and the driven shaft. A flexible shaft or roller for auxiliary forming is also set on the upper part of the lower flexible shaft. The structure is complex and the forming accuracy is not high.
