Gas-electric compound drive precise glass die forming machine and operation method

Abstract

The invention discloses a gas-electric compound drive precise glass die forming machine and an operation method. The die forming machine comprises a console, a feeding component, a die forming machinemain body, a discharging component and a rack component, wherein the feeding component drives an assembly to successively pass through two feeding doors, only one feeding door is open at one time, and nitrogen is sprayed nearby the open feeding door in an incremental way for preventing the air from entering a forming cabin, and a nitrogen protection atmosphere inside the die forming machine mainbody is prevented from being destroyed; the die forming machine main body carries out multi-station transmission and processing on a prefabricated member; a discharging component drives the assembly to successively pass through two discharging doors, only one discharging door is open at one time, and nitrogen is sprayed at the open discharging door in an incremental way for preventing the air fromentering the forming cabin, so that the nitrogen protection atmosphere inside the die forming machine main body can not be destroyed. The as-electric compound drive precise glass die forming machinedisclosed by the invention has the technical advantages in many aspects such as high control accuracy, stable performance and high die forming quality.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to an electric composite drive precision glass molding machine. Background technique [0002] As we all know, there is a huge market demand for optical lenses such as spherical, aspherical, and free-form surfaces, optical microstructures such as microprism arrays, microlens arrays, and micro-groove arrays, and optical devices with complex curved surfaces such as Fresnel lenses. It is made of optical materials such as optical glass and infrared glass. Thermoforming technology is currently a new process for processing optical components, showing great potential. [0003] Thermoforming technology processes optical components, that is, the glass preform is first placed in a high-precision mold, and then pressure is applied in a high temperature and oxygen-free environment to directly press and form an optical device that meets the requirements for use. By changing the s...
