Heavy-caliber quartz capsule/stick drawing molding device

Abstract

The invention provides a big-bore quartz tube/rod drawing and forming device, comprising a frame, wherein, the frame is vertically provided with 1 to 3 groups of traction mechanisms; each group of the traction mechanism comprises a pair of drawer rollers arranged in bilateral symmetry; the drawer rollers are fixed in the middle of a swing axle; a transmission shaft is arranged above the swing axle; two ends of the swing axle are hung under the transmission shaft through a left connecting swinging arm and a right connecting swinging arm; the frame is provided with a front box board and a back box board; two ends of the transmission shaft are arranged between the front box board and the back box board of the frame; synchronous regulating gears engaged with each other are arranged between the connecting swinging arms of each group of the traction mechanism; an exit tube operating hole consisting of each group of the drawer rollers is arranged inside a box body of the frame; all the transmission shafts form a closed circulating drive system through a chain I according to the working rotation speed of each group; and an independent chain is adopted for transmission from the swing axle to the transmission shaft, thereby forming an independent work system for each group; the whole device is assembled reasonably, so the accumulation of mechanical clearance error is eliminated. Balanced pressure and stable operation can be ensured when the drawer rollers operate.

Description

technical field [0001] The invention relates to a molding equipment for quartz glass tubes or quartz glass rods, in particular to a drawing and molding device for ultra-large-diameter quartz tubes / rods of about Φ450 mm. Background technique [0002] Ordinary quartz tubes / rods are formed by smelting quartz in a melting furnace and then drawing it into a tube drawing machine. At present, the production of quartz tubes / rods is all small-caliber, so the tube-drawing machines in the current technology are all cantilever structures designed for small-caliber quartz products. It is driven by gears with the transmission wheel. When working, each group of large gears drives the small gears and the coaxial working traction wheels outside the box to rotate, forming a pair of working traction wheel working surfaces that turn in opposite directions. Generally, there are 1 to 3 groups, which are clamped and flowed down by the furnace former. The quartz tube blank is drawn into shape. A...

AI Technical Summary

Problems solved by technology

Since the working traction wheels of this device are installed outside the box to form a cantilever, and the overall frame is welded by angle iron, the center of gravity of the whole machine moves upward, which causes the vertical sides of each pair of working traction wheels to be unbalanced with each other, and it is easy to vibrate when running at high speed, resulting in The outer diameter of the produced quartz tube / rod is different, the wall thickness of the tube is uneven, and the qualified rate of the product is reduced
