Embodiment Construction

[0009] After canceling the loading and heating section of the glass horizontal tempering production line, it can be connected with the forming transition section of the flat glass production line (such as the transition roller table of the float glass production line) to form a tempered glass online production line.

[0010] The above online quenching equipment and online hot bending equipment can also be set in the glass annealing furnace, so that the glass production line can produce flat (bent) tempered glass or flat (bent) ordinary glass online.

[0011] The laser head of the laser glass cutting machine can be set above the glass plate at the rear end of the tin bath, below or above the glass plate at the transition roller table, or below or above the glass plate at the glass inlet end of the annealing furnace.

Abstract

The invention relates to a plate glass on-line hot-state cutting and toughening technique which is characterized by comprising the following steps: arranging an on-line plate glass transverse cutting or\and longitudinal cutting apparatus in a certain section position at the hot end of a glass production line; carrying out on-line quenching and toughening on the cut hot-state glass plate with an on-line quenching apparatus, or carrying out on-line quenching and toughening with an on-line quenching apparatus after carrying out on-line hot bending with an on-line hot bending apparatus. The certain section position at the hot end of the glass production line refers to a certain section position of the glass plate after molding and before starting annealing. The on-line plate glass transverse cutting or\and longitudinal cutting apparatus is a laser glass cutting machine.

Description

technical field [0001] Cutting and tempering of flat glass, especially online cutting and tempering. The so-called "online" here refers to various flat glass production lines (such as: float glass production line, flat drawn glass production line, rolling glass production line). Background technique [0002] At present, the cutting equipment for online flat glass is installed at the cold end after the annealing kiln of the glass production line. Since the online flat glass will swing laterally during operation, its cutting equipment is generally equipped with a glass plate tracking detection and cutter head tracking adjustment mechanism, which is not only complicated to control and maintain, but also has high manufacturing costs; and mechanical cutting and breaking Breaking can easily cause damage to the glass plate. [0003] At present, the tempering of flat glass is done through various off-line flat glass tempering furnaces. The tempering process is as follows: seconda...
