Flexible pressing mechanism for glass forming

Abstract

The invention discloses a flexible pressing mechanism for glass forming. The flexible pressing mechanism comprises a rack arranged above a forming mechanism, and further comprises a plurality of pressing cross beams arranged at intervals in the direction perpendicular to the glass conveying direction. A plurality of rollers rotating freely are arranged on the pressing beam at intervals in the length direction of the pressing beam, the two ends of the pressing beam are connected with flexible mechanisms through supporting blocks respectively, and a torsion motor connected with the pressing beamis installed on one supporting block so as to drive the pressing beam to rotate around the axis of the pressing beam relative to the supporting block. A plurality of vertical telescopic mechanisms are rotationally arranged at the top of the rack and connected with the flexible mechanisms in a one-to-one correspondence mode so as to lift the pressing cross beam, a plurality of lateral telescopic mechanisms are rotationally arranged on the two sides of the rack respectively, and the lateral telescopic mechanisms are rotationally connected with the vertical telescopic mechanisms. The flexible pressing mechanism can adapt to the shapes of bent glass or special-shaped glass in different shapes, so that each roller can be vertically pressed on the upper surface of the glass, and the glass forming precision and the surface quality are ensured.

Description

technical field [0001] The invention belongs to the field of special-shaped glass forming equipment, and in particular relates to a flexible pressing mechanism for glass forming. Background technique [0002] During the forming process of forward bending tempered glass or reverse bending tempered glass, generally the glass heated to a softened state enters the forming equipment and is formed with the arc forming of the forming roller table. For large radius glass, the deformation range is small. The glass can be well attached to the forming roller table without the need for a pressure roller. However, for glass with a small radius, due to the large bending range of the glass, the edge of the glass may have a tendency to rebound. At this time, it will generally The way of setting down the pressing mechanism is adopted, and the rollers in the pressing mechanism are pressed on the upper surface of the glass to keep the shape of the glass. When the pressing mechanism presses do...

Problems solved by technology

[0003] For special-shaped glass, such as wavy glass, V-shaped glass, etc., the deformation of such special-shaped glass is very large during molding, so it is necessary to configure rollers as the pressing mechanism. Due to the various shapes of such special-shaped glass, the current pressing mechanism It cannot be guaranteed that the rollers can be perpendicular to the contact part of the upper surface of the glass, and even some rollers may not touch the glass, so the forming accuracy and surface quality of the glass will be affected during the movement of the glass
