Technical Field

The invention relates to the technical field of toughened glass production, in particular to a device and a method for producing single-curved arc-surface toughened glass based on linear walking.

Background

At present, the production method of single-curved arc surface toughened glass mainly comprises the steps of heating the glass to the temperature required by the process, transferring the glass to a forming toughening section for cold quenching to obtain a product, and if the glass is divided according to the process direction of the glass in the forming toughening section during cold quenching, a straight line mode and a spiral mode exist.

Among them, the straight line method is a commonly used method. The forming and tempering section consists of a lower part and an upper part which are arranged oppositely and respectively comprises a plurality of mutually parallel main beams, a plurality of forming wheels and a plurality of blowing nozzles which are attached to the main beams, and the process direction of the main beams is linear motion parallel to the main beams when the main beams are subjected to cold quenching after glass forming. Due to the superposition of the existence of the main beam and the linear motion, when the blowing nozzle performs blowing and cold quenching, the cooling degree of gaps between the main beam and the main beam on the glass at the normal projection part of the glass is inconsistent, the stress is not uniform, the tempered wind spot is serious, and the strength and the optical quality of the tempered glass are seriously influenced.

The spiral mode is generated for solving the problems existing in the linear mode, for example, the device and the method for producing the single-curved arc surface toughened glass disclosed in the Chinese patent with the patent number of CN107140814B are characterized in that a certain included angle is formed between the axis of the forming wheel and the axis of the main beam, and in the cold quenching process, the movement track of the glass bent into the single-curved arc surface is spiral relative to the movement track of the single-curved arc surface formed by the outer diameter buses of the forming wheels. The method well solves the problem that the prior single-curved arc surface toughened glass has serious wind spot and improves the optical quality of the product, but the patent has the following technical problems in implementation: because a certain included angle is arranged between the axis of the forming wheel and the axis of the main beam, the glass bent into the single-curved arc surface is in a spiral line relative to the movement track of the single-curved arc surface formed by the outer diameter buses of each forming wheel, therefore, the glass bent into the single-curved arc surface can continuously swing left and right in the walking direction perpendicular to the production process in the movement process, in order to prevent the glass bent into the single-curved arc surface from being exposed outside the forming section to influence the optical quality, the effective width and the size of the forming section must be increased, and therefore, the effective widths of the heating furnace and the loading and unloading device must be increased, the waste of effective resources of equipment is caused, the self cost and the operation cost of the equipment are increased, the requirement on the installation site of the equipment is increased, and the large-scale use of the equipment is not facilitated.
