荫罩成型模主要零件的重要部位需要加工成曲线或曲面。其计算十分复杂,通常采用通用的计算程序,经计算机计算荫罩成型模设计需要的尺寸。一、产品零件荫罩与荫罩成型模主要零件随着彩电工业的发展,彩色电视机品种和规格得到了迅速开发,作为彩电显象管内的关键零件荫罩,也相应地进行改进与开发。荫罩主要改进之处,有两个方面:一是由于彩色电视机屏面变得扁平,荫罩的曲面曲率相应变小;二是随着彩色电视
Shadow mask forming an important part of the main parts need to be processed into a curve or surface. The calculation is very complicated, usually using a common calculation program, calculated by the computer shadow mask design required size. First, the product parts shadow mask and shadow mask forming the main parts With the development of color TV industry, color TV sets and specifications have been developed rapidly, as a key part of CRT TV shadow mask, also be improved and developed accordingly. Shadow mask major improvements, there are two aspects: First, as the color TV screen becomes flat, the curvature of the shadow mask corresponding smaller; second is with the color TV
