A quartz glass mound making machine

Abstract

The invention discloses a quartz glass mound making machine, which comprises a base plate, a screw lifter is arranged on the upper surface of the base plate, a swing table mechanism is arranged on the upper end of the screw lifter, and a support is fixedly connected to the upper surface of the base plate. A frame, the support frame is provided with a detection mechanism for detecting the feeding speed. In the present invention, in the process of making mounds, the detection mechanism is used to detect the change of the cutting speed, so as to control the operation of the oil pump, and the oil pump controls the flow of hydraulic oil in the pipeline, so as to cooperate with the push rod and the push ring to change a plurality of first arc-shaped plates and the distance between the second arc-shaped plate, so as to realize the adjustment of the transmission ratio between the screw rod and the round tube, to achieve the purpose of adjusting the rotation speed of the turntable, and to avoid the appearance of glass being pulled on the appearance of the molten mound, so that the crystal grains slide along the stress direction, It is not obvious that it is pulled out and the structure of the fused mound is uneven.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a quartz glass mound making machine. Background technique [0002] With the rapid development of electronics industry, electric light source industry and optical communication technology, quartz glass products are also facing higher and higher requirements. The transparent quartz glass pipe or rod produced by the traditional one-step method cannot meet the requirements due to defects such as corrugation and grooves. In this way, a new process method-two-step method of gas refining and electric melting came into being. In this method, the crystal powder is smelted into a quartz lump on special equipment with a hydrogen-oxygen flame as a heat source, and then drawn into a material in a resistance furnace after cold processing. This process overcomes the above-mentioned shortcomings, and the product quality is better, which meets the requirements of use. [0003] In the e...

Problems solved by technology

[0003] In the existing technology, but in the actual processing process, due to the influence of unstable factors such as furnace temperature, material feeding amount, and material yield, the actual cutting speed has certain changes, and the rotation speed of the swing table does not change synchronously, resulting in the appearance of melting mounds. There are signs of glass being pulled, the crystal grains slide along the stress direction, the pull-out phenomenon is more serious, and the fused mound structure is uneven. Therefore, we propose a quartz glass mound making machine to solve the above problems
