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...

Problems solved by technology

However, limited by the quality of the air source, the accuracy and stability of the output force of most cylinders are poor, that is, the output force is difficult to reach the predetermined value and the value itself has large fluctuations

[0010] For example: as a means of preventing oxidation, nitrogen protection has the advantages of low cost and low requirements on the sealing of the processing chamber. However, most molding machine tools currently only directly connect the nitrogen source to the processing chamber, and lack the control of nitrogen pressure and flow rate. The control method is insufficient in flexibility and adaptability in the process of process changes and the opening and closing of the entrance and exit of the forming chamber

[0011] For example: the infrared heating method is a relatively mature molding heating method, which is widely used in molding machine tools, but the infrared heating device is large and fixed, and it will not only take up too much space in a compact multi-station molding machine tool, but also This reduces the adaptability to molds of different specifications, and the structure of the infrared heating lamp is complex, easily damaged, and the energy utilization rate is low, which is not conducive to reducing production costs
