Problems solved by technology
[0005] The main purpose of the present invention is to provide a chalcogenide glass rod extrusion molding device and process. The technical problem to be solved is to overcome the problem that the materials at both ends of the rod cannot be used and improve the material utilization rate through the improvement of the forming device. ; Shorten the bar extrusion molding time through process optimization, improve the molding efficiency; at the same time, the molding device provided by the technical solution of the present invention is a vertical molding, on the one hand avoids the unevenness of the ellipticity caused by the influence of gravity on the formed bar The symmetrical quality problem, on the other hand, also solves the problem that the equipment occupies a large area and wastes the workshop space, so it is more suitable for practical use.

Abstract
The main purpose of the present invention is to provide a chalcogenide glass rod forming device and method. The device includes: a chemical material system, which includes a heating furnace with a quartz cavity embedded inside; an opening is provided at the bottom of the quartz cavity; a cylindrical mold, which is embedded in the heating furnace and arranged on the Downstream of the quartz cavity, one end is connected to the opening; the atmosphere control system includes a vent hole and a vent hole; the vent hole, the vent hole and the quartz cavity form a closed space to control the atmosphere in the heating furnace; The pressing system includes a quartz indenter whose lower end surface is a spherical crown convex structure; a protruding boss with a flat lower end surface is arranged on the top of the convex surface. The described device and method overcome the problem that the material at both ends of the bar cannot be used through the improvement of the forming device, and improve the utilization rate of the material; through the improvement of the device and the optimization of the process, the extrusion molding time of the bar is shortened, and the forming efficiency is improved, thereby more practical.
Description
Technical field [0001] The present invention belongs to the technical field of sulfur glass secondary thermoforming technology, and more particularly to a sulfur glass bar material forming apparatus and method. Background technique [0002] The sulfur glass is considered a new generation of temperature adaptive infrared light system core lens material, which can be widely used in military and civil infrared systems. With the increasing extensive extensive application in military and civilians, infrared lenses rapid and low cost acquisition techniques have become an important factor in restricting the popularity and development of sulfur glass products. Its technical barrier is that the traditional infrared lens blanks need to pass through larger blaming cuts, decomposition, grinding, softening pressure, etc. The utilization rate of materials is not high, and the product rate is low. [0003] In order to solve the above problems, there is a study proposing a rapid acquisition of a...
