INSTALLATION FOR DRAWING PRODUCTS FROM GLASS BLANKS Russian patent published in 2022 - IPC C03B17/04 C03B23/47 

FIELD: construction.

SUBSTANCE: proposed invention relates to the industry of construction and building materials, to equipment for the formation of products from glassy materials by pulling by the similarity method, in particular to the field of manufacturing high-precision glass capillaries, rods, complex microstructures and can be used in the manufacture of products for the chemical, biological, electronic industries , in particular for the fabrication of precise microstructures. The installation for pulling products from glass blanks includes a billet feeding mechanism, a billet feeding mechanism carriage installed in the frame, a billet heating furnace with a spiral heater on the inner wall of the furnace body, a thermal stabilization chamber, a geometric parameters control sensor, a pulling mechanism, a strain gauge, cutting and sorting mechanisms and a control unit. The unit is equipped with a mechanism for accelerated lifting of the carriage to its original position, containing an asynchronous motor with a driving pulley and a V-belt, connected to the carriage through a ball screw, which is connected to the feed mechanism through a coupling. Also, the installation is equipped with a strain gauge system, including a plate suspended at one end on a prism by means of a wedge, at the other end of which a strain gauge is fixed. The plate on the side of the load cell is connected to the pulling mechanism, and on the opposite side it is equipped with a counterweight. The pulling mechanism is made in the form of a chain mechanism, in which fists with grooves having straight and curved sections are installed on the driving and driven sprockets. The inner wall of the furnace is made of quartz tube.

EFFECT: improving the quality of products when pulling the workpiece by reliably measuring the pulling force, which excludes the influence of a decrease in the weight of the workpiece with an increase in the productivity of the process.
