Embodiment 2

[0023] Embodiment 2: the top inside the pretreatment chamber 12 is fixedly connected with the first cylinder 13, the bottom end of the first cylinder 13 is fixedly connected with the scraper 17 through the piston rod, and the two ends of the inner wall of the pretreatment chamber 12 are all provided with heating copper pipes 20. A washing tank 14 is installed on the other side of the top of the pretreatment chamber 12, and a high-pressure pump 15 is installed on the outside of the washing tank 14, and a nozzle 16 is installed on the other side of the top inside the pretreatment chamber 12, and there are multiple groups of nozzles 16 and arranged at equal intervals, the nozzle 16 and the high-pressure pump 15 are connected through a water guide pipe, and a water collection tank 19 is arranged under the nozzle 16;

[0024] Specifically, such as figure 1 , figure 2 with Figure 4 As shown, before entering the heating furnace 6, the glass workpiece 24 first enters the pretreatm...

Embodiment 3

[0025] Embodiment 3: Two sets of second cylinders 5 are fixedly connected to the top of the cooling table 4, and the output ends of the second cylinders 5 are fixedly connected to a fixed frame 3 through a piston rod, and an air cooler 2 is installed at the bottom of the fixed frame 3;

[0026] Specifically, such as figure 1 As shown, after the glass workpiece 24 is heated in the heating furnace 6, it arrives at the cooling table 4, and the second cylinder 5 drives the air cooler 2 at the bottom of the fixed frame 3 to lift up and down through the piston rod, thereby adjusting the surface of the air cooler 2 and the glass workpiece 24. The distance is suitable for cooling glass with different curvatures. The initial distance between the air cooler 2 and the glass workpiece 24 is relatively small. As it continues to drop, the wind speed is adjusted to the maximum to gradually cool the glass surface, thereby avoiding overheating. Move, reduce damage to the mold, improve the effi...

Abstract

The invention discloses forming equipment for hot bending of glass. The equipment comprises a processing table and a heating furnace, a heating furnace is arranged at the top end of the machining table, a cooling table is arranged on one side of the heating furnace, a pretreatment chamber is arranged on the other side of the heating furnace, and a heat insulation plate is installed at the top end of the heating furnace. A hydraulic oil cylinder is fixedly connected to the top end of the heat insulation plate, a hydraulic rod is arranged at the output end of the hydraulic oil cylinder, the hydraulic rod extends into the heating furnace and is fixedly connected with an upper die base, telescopic rods are fixedly connected between the two sides of the top end of the upper die base and the heat insulation plate, and electric heating wires are arranged at the bottoms of the two ends of the heating furnace. According to the forming equipment for hot bending of the glass, the pretreatment chamber is arranged, and a glass workpiece enters the preheating area, is heated by the heating copper pipe and can be preheated before entering the heating furnace for high-temperature heating, so that deformation caused by internal stress due to overlarge temperature difference before temperature rise is avoided, the forming quality is improved, and the problem of poor forming quality is solved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a forming device for hot bending of glass. Background technique [0002] Curved glass is widely used in production and life, ranging from automobile windshields to small mobile phone curved screen tempered films. The hot bending process of glass has formed a mature industrial chain. In the hot bending process of glass, heating copper tube or heating wire is usually used to heat up the mold, so that the glass is hot-pressed and formed at a high temperature. At present, in the actual use of many glass hot-bending forming equipment on the market, there are still problems such as inconvenient safe and efficient heating, easy deformation by direct heating, and surface defects caused by insufficient dust removal on the outer surface. Contents of the invention [0003] The object of the present invention is to provide a forming equipment for hot bending of glass, so as to so...
