Problems solved by technology

[0002] When materials are precisely formed by heat bending, there are two main methods for recording the heat bending process: one is that the glass is formed by heat bending in an oven, and the researchers visually observe the forming process through the observation window of the oven. Strong dependence, and the angle of observation is limited, only part of the hot bending process can be observed; another method is to install a camera inside the oven to record the hot bending process through video; but the video information can only record the thermal bending process. development of the bending process without being able to output it as accurate and quantitative digital information
[0003] At present, no effective measurement system and measurement method have been found to quantitatively record the process of glass thermal bending deformation

Embodiment

[0087] Draw a grid S less than 20mm on the surface of the plexiglass of the material to be processed 1 and mark points A, B, C..., then fix the thermal processing mold and the plexiglass to be processed, and put them into an oven to shape the plexiglass at 115°C; measure the temperature of the plexiglass during the thermal processing in real time out of shape.

[0088] A gantry bracket is arranged in the oven, and a slide rail and a slider are arranged on the straight beam of the bracket; the slider can move along the slide rail; a detection head is installed at the lower end of the slider; the surrounding of the detection head is Wrap the flexible silicone tubing with built-in cold water circulation; then, wrap the flexible silicone tubing with insulating cotton. Adjusting the positions of the bracket and the thermal processing mold enables the detection head to clearly detect the states of each point on the plexiglass during the whole process of thermal processing.

Abstract

The invention provides a hot working process online measurement system and a transparent material dynamic deformation measurement method. The online measurement system includes: a detecting head; a cooling unit wrapping the outer circumference of the detecting head; and a moving mechanism, wherein the detecting head is fixedly mounted on the moving mechanism, and scans a measured hot working material when moving along with the moving mechanism. The measurement method comprises: performing surface treatment on the transparent material; enabling the detecting head to move and scan the transparent material, and acquiring the measurement data of the transparent material at any detection point at any time along a time axis. The online measurement system and the measurement method can measure the state of the transparent material at any detection point at any time and output a digitized result, can accurately and quantitatively record the measurement result at any time during the dynamic deformation process of the transparent material and output the digital record, provide a valuable reference basis for the determination of a material hot working process, and are practical.
