AI Technical Summary

Technical Problem

In the existing quartz tube forming process, the high viscosity and poor fluidity of the molten quartz solution make it difficult to remove air bubbles, resulting in low density and affecting the mechanical strength and forming quality of the quartz tube, making it difficult to meet the requirements of high-precision applications.

Method used

An ultrasonic vibrating block is used to expel air bubbles inside the molding die, and the die is driven to rotate by a transmission mechanism to generate centrifugal force. Combined with a sealing injection and cooling system, this ensures that the molten quartz solution is tightly molded.

Benefits of technology

It effectively removes air bubbles, improves the density and molding quality of quartz tubes, enhances the mechanical strength and consistency of products, and meets the requirements of high-precision applications.

Abstract

The invention provides molding equipment for quartz tube production, which belongs to the technical field of quartz tube production equipment and specifically comprises a power transmission module and a molding module. Wherein the power transmission module comprises a driving part and a transmission mechanism, and the driving part is in transmission connection with the forming module through the transmission mechanism so as to drive the forming module to rotate around the axis of the forming module; the forming module comprises a vertically arranged forming mold and an upper sealing mechanism, the upper sealing mechanism is in sealing fit with the forming mold, and the upper sealing mechanism is provided with a liquid guide structure used for injecting a fused quartz solution into the forming mold; at least one ultrasonic vibration block is arranged in the forming mold and is used for discharging gas in the fused quartz solution; the transmission mechanism drives the forming mold to rotate to generate centrifugal force, and the vibration effect of the ultrasonic vibration block is matched, so that the fused quartz solution is compactly formed into the quartz tube, and the finished product quality is improved. Through the synergistic effect of centrifugal force and ultrasonic vibration, bubbles and stress concentration in the quartz tube are effectively reduced, and the uniformity of the tube body is improved.
