Description
Technical Field
The invention relates to a preparation method of toughened glass.
Background
The hot bending glass is curved glass which is made by heating, bending and softening high-quality glass, forming in a mould and annealing in order to meet the high-quality requirements of modern buildings. The style is beautiful, and the lines are smooth. The glass breaks through the singleness of the plate glass, and is more flexible and diverse in use. The method is suitable for special requirements of different shapes such as fish tanks, dining tables, balconies, mobile phone counters, cosmetic counters, hot bending television cabinets, doors, windows, ceilings, curtain walls and the like.
At present, curved surface toughened glass is generally formed by processing plane toughened glass through a hot bending processing die matched with a heating device, the main principle is that the plane toughened glass is placed into the hot bending processing die, then the toughened glass is heated, the toughened glass is heated to be softened and each part is bent under the action of self gravity, and finally the bent amplitude of the following die is shaped. For hot-bending glass with large radian (the arc length is more than 4500mm), the processing difficulty is high, and the condition that the curve of the glass cannot be well matched with a mold easily occurs.
Disclosure of Invention
In order to solve the above drawbacks, the present invention provides a device for manufacturing large-radian thermally-bent tempered glass, so that the curve of the glass is well matched with the mold. In order to solve the technical problems, the invention adopts the technical scheme that the device for preparing the large-radian hot-bent toughened glass comprises a heating furnace and a hot-bending processing die, and is characterized by also comprising a forming intervention mechanism, wherein the forming intervention mechanism comprises two sets of lead screw nut mechanisms arranged on two opposite side walls of the heating furnace, and a lead screw stepping motor is arranged outside the heating furnace; two ends of a translation cross beam are respectively connected with nuts of the screw nut mechanism, at least two chain wheels are sleeved on the translation cross beam, a chain is meshed with the chain wheels, the A end of the chain penetrates through an observation window of the heating furnace and is led out of the heating furnace, the A end is connected with a winding roller, and the winding roller is connected with a roller stepping motor; the B end of the chain is fixedly connected with a lifting cross beam, and rotating shafts at two ends of the pressing roller are arranged on the lifting cross beam; the pressing roller consists of a counterweight core rod and a fireproof cloth outer sleeve; the pressing roller is correspondingly positioned above the hot bending processing die.
The invention has the advantages that in the heating softening molding process, when the curve of the glass can not be well matched with the mold, the translation beam is driven by the lead screw stepping motor to move to the position above the non-matched part; the roller stepping motor unreels the chain, and the freely rotatable pressing roller descends to roll the corresponding part to ensure that the corresponding part is matched with the die for molding; meanwhile, the molding intervention mechanism works effectively and reliably; is suitable for the high-temperature working environment in the heating furnace.
In order to avoid the obvious mark of the glass caused by the overlarge impact of the pressure applying roller, the rotating shafts at two ends of the pressure applying roller are preferably arranged on the lifting cross beam through a buffer mechanism. Preferably, the structure of the buffer mechanism is that mounting cavities are formed in two ends of the lifting beam, buffer springs are arranged in the mounting cavities, and bearing seats of rotating shafts at two ends of the pressing roller are hoisted in the mounting cavities through the buffer springs.
