我厂以前生产的雨刷刮片是直接模压成形不经切割加工的,因此刮擦清洁度比较差,不能满足提高汽车质量的要求。一九七八年总厂六十四项产品更改中,我厂产品设计对雨刮器(特别是雨刷刮片)提出了改革要求。当时国内雨刷刮片多不经切割加工,因此对刮片的技术条件也无可借鉴。后来根据一份日本资料上对刮片的论述,给新的雨刷刮片规定了两点技术要求:1、沿长途方向必须平直;2、刀口横截面作投影放大检查,应呈规则距形无倾斜凹陷及圆角,对圆角的要求是放大三十倍 R<1。日本资料是放大九十倍检查,但无具体数据。
The wiper blade that our factory produced before is the direct molding does not cut and process, so the scratch cleanliness is relatively poor, can not meet the requirement of improving the car quality. In 1978 the General Factory sixty-four product changes, I plant product design wiper (especially wipers scraper) put forward the reform requirements. At that time, domestic wipers and more without cutting blade processing, the technical conditions of the blade is no reference. Later according to a Japanese data on the blade of the discussion, to the new wiper blade provides two technical requirements: 1, along the long direction must be straight; 2, the knife cross-section for projection magnification inspection, should be regular spacing No inclination of depression and fillet, the fillet requirements is to enlarge thirty times R <1. Japan is to enlarge the data is ninety times the check, but no specific data.
