There are also colored glass mixed with some metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes, some transparent plastics (such as polymethyl methacrylate) are also called organic glass.

[0003] With the difference of building style, the shape of the glass used is also different, and the bending steel glass is one of the mainstreams. The bending steel glass is widely used in building doors and windows and curtain walls, and can be processed into different shapes and sizes as needed to meet the diversified building needs and enhance the building aesthetics and structural strength.

[0004] Because the bending steel glass has a beautiful bending radius, its processing technology is more complex than that of flat glass. The flat glass after processing needs to be heated close to the softening point, and then bent into the required shape through a mold or using auxiliary tools. However, it is difficult to control the pressure of the mold during this process, and it is easy to cause the formed glass to be difficult to meet the production standard. Therefore, a new technical solution is needed to solve the problem, which can limit the mold that is pressed down and control the radius in the bending steel glass processing process to ensure the production efficiency of the bending steel glass.

[0024] In some technical schemes, the shafts of the adjacent two groups of pushing rollers 12 are connected in transmission through the first transmission belt 13, and the shafts of the adjacent two groups of pressing rollers 26 are connected in transmission through the second transmission belt 3, so that the pressing rollers 26 and the pushing rollers 12 distributed in the two groups can be synchronously rotated outward, the shafts of the pushing rollers 12 distributed on the two sides of the fixed frame 1 are fixedly connected with the motor shafts of the two groups of first motors, and the shafts of the pressing rollers 26 distributed on the two sides of the pressing table 14 are fixedly connected with the motor shafts of the two groups of second motors, so as to drive the pressing rollers 26 and the pushing rollers 12 to rotate.

[0029] In use, first, the heated flat glass is placed on the plurality of push rollers 12, and under the drive of the first motor, the plurality of push rollers 12 are rotated to move the flat glass to the bottom of the pressing table 14. After the two hangers 34 are lifted to push the flat glass to the bottom of the plurality of pressing rollers 26, the flat glass is bent, and when the high-temperature flat glass contacts the bottom pressing roller 26, the two hangers 34 will continuously move to the center of the concave frame 31, and the plurality of work frames 11 will be pulled to push the flat glass in a circular arc shape. After each group of work frames 11 pushes the flat glass to the side wall of the plurality of pressing rollers 26, the adjusting seat 22 will continuously move upwards, and when the pressure between the adjusting seat 22 and the pressing table 14 reaches the set value of the pressure sensor 24, the signal will be transmitted to the control processor to stop driving the hydraulic push rod 15 and the third motor.
