All motor-driven precision compression molding machine and operation method

Abstract

The invention discloses an all motor-driven precision compression molding machine and an operation method. The compression molding machine includes a console and a feeding component, a compression molding machine main body, a discharge component and a rack component. The feeding assembly is used for sending a die and an assembly of a prefabticated member into the compression molding machine main body; the compression molding machine main body is used for machining the prefabticated member; the compression molding machine main body consists of compression mechanisms, a shift fork mechanism, a forming cabin and nitrogen delivery ports; a plurality of nitrogen delivery ports are disposed outside the compression molding machine main body for inputting nitrogen into the forming cabin to guarantee that after certain period of time, the nitrogen concentration can exceed a critical point so as to form a protective atmosphere, thus preventing oxidation of the prefabticated member and the die athigh temperature; and the discharge component is used for sending the assembly out of the compression molding machine main body. The driving mode has the characteristics of high control precision andconvenient operation. Motor driving can ensure that the control precision of die closing speed, position and forming force meets the technical requirements, and then can improve the product quality.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to an all-motor-driven precision 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. At present, optical device processing can be divided into the following three categories: [0003] The first category is the use of mechanical processing, mainly including single-point diamond turning, ultra-precision grinding and various polishing processes. Machining methods can process most optical components, and can achieve extremely high processing accuracy. [0004] The second category is the use of photolithography processin...

AI Technical Summary

Problems solved by technology

The optical material molding machine tool developed by thermoforming technology has already been commercialized; however, most of the molding mechanisms on the market use cylinders, which have problems such as low control accuracy of mold clamping speed, position and forming force. It directly affects the improvement of technical indicators such as surface accuracy and roughness of molded products; at the same time, the pneumatic drive needs to be equipped with an independent compressed air supply system, and additional air compressors, voltage stabilization and drying and filtering equipment are required, which increases the cost of system equipment; in addition The current molding machine is mainly controlled by PLC. Although its stability is relatively good, its computing power is far inferior to that of an industrial PC inserted into a motion control board, and its response speed and controllable degree of freedom are not high.
