Problems solved by technology
[0003] Since the working temperature in the hot bending furnace of the hot bending machine reaches about 700°C, in order to prevent the stainless steel components in the furnace from being oxidized at high temperature, it is necessary to continuously input a sufficient amount of nitrogen into the furnace to reduce the concentration of oxygen in the air in the furnace. content, but the airtightness in the existing hot bending furnace cannot be guaranteed, the oxygen content cannot be accurately controlled, and stainless steel components are often oxidized at high temperatures

The invention discloses a glass hot bending machine and an oxygen content monitoring method for a hot bending furnace of the glass hot bending machine. The glass hot bending machine comprises the hotbending furnace and an oxygen content monitoring system; the oxygen content monitoring system comprises a controller, a nitrogen tank, a vacuumizing device, a detection probe and an oxygen content analyzer; the nitrogen tank is communicated with the hot bending furnace and used for inflating the hot bending furnace with nitrogen; the vacuumizing device is communicated with the hot bending furnaceand used for pumping out gas from the hot bending furnace; the detection probe is installed inside the hot bending furnace; the oxygen content analyzer is connected with the detection probe and used for analyzing the oxygen content inside the hot bending furnace according to collection information of the detection probe; the controller is electrically connected with the oxygen content analyzer, the vacuumizing device and a valve of the nitrogen tank. According to the technical scheme, the oxygen content inside the hot bending furnace can be monitored, and the problem that a stainless steel component inside the hot bending furnace is oxidized under high temperature is solved.
Description
technical field [0001] The invention relates to the technical field of glass forming, in particular to a method for monitoring the oxygen content of a glass bending machine and a bending furnace of the glass bending machine. Background technique [0002] Hot bending glass is a curved glass made by heating and softening flat glass in a mold, and then annealing and cooling. Hot bending glass is widely used and can be made into glass of various radians. Hot bending glass can be used in sightseeing elevators, halls, revolving top floors, street passages, viewing windows and other occasions. In recent years, it is especially popular in the application of electronic products, such as front and rear covers of mobile phones. [0003] Since the working temperature in the hot bending furnace of the hot bending machine reaches about 700°C, in order to prevent the stainless steel components in the furnace from being oxidized at high temperature, it is necessary to continuously input a...
