Abstract

The invention relates to an extrusion forming device and process for a small-caliber chalcogenide glass bar material, belonging to the technical field of secondary thermal forming of chalcogenide infrared glass. The process is a mechanical forming process for the small-caliber chalcogenide glass bar material. The extrusion forming device is mainly characterized by comprising an extrusion mechanism, a heating furnace, a mold, a riding wheel mechanism and a panel, wherein the heating furnace is fixed at one end of the panel; the riding wheel mechanism is fixed at the other end of the panel; the lower section of the cylindrical-step-shaped mold penetrates through the bottom of the heating furnace, and an air tube and an end cap are arranged at the lower section of the mold outside the heating furnace. According to the extrusion forming device and the extrusion forming process, by forming a once-fused chalcogenide glass blank into the small-caliber chalcogenide glass bar material by virtue of the mold, the rapid acquiring of lenses with corresponding calibers can be directly met, the weights of larger-caliber blanks can be precisely acquired, lots of procedures in secondary forming and material preparation links are reduced, the yield is increased, the material loss in the material preparation link is saved, and the manufacturing cost of chalcogenide infrared lenses is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of secondary thermoforming of chalcogenide infrared glass. Specifically, it relates to a device and a process for heating and softening a molten chalcogenide infrared glass block material in a cavity, extruding it with mechanical external force, and forming it into a small-diameter bar through a mold nozzle. Background technique [0002] In recent years, chalcogenide infrared glass lenses have been widely used in military and civilian fields such as battlefield investigation, individual helmets, vehicle navigation, online infrared monitoring, infrared thermal imaging monitoring, infrared night vision equipment, etc., but the production of infrared lenses The high cost has restricted the popularization and development of infrared products. [0003] The high manufacturing cost of chalcogenide infrared glass lens is mainly reflected in several aspects: ① high price of production raw materials; ② large materi...
