风板机柄体和前体一般为铝铸件。由于这些零件的结构复杂(件内有互相隔离而又有一定位置要求的细长气道),给铸造带来一定困难。采用砂型铸造,铸件合格率低,一般仅为50%左右;表面光洁度不高,影响产品外观质量。我厂铸工车间工人,发扬敢攀技术高峰的革命精神,以毛主席光辉哲学思想为武器,抓主要矛盾,反复实践,攻克了砂型铸造的一道道难关,使铸件合格率稳定提高到95%以上,而且表面光洁度不亚于金属模压铸。
Fan handle and precursor body is generally aluminum castings. Due to the complex structure of these parts (the pieces are isolated from each other and have a certain location of the elongated airways), to bring some difficulties casting. The use of sand casting, castings pass rate is low, generally only about 50%; surface finish is not high, affecting the appearance of product quality. I plant casting workshop workers, to promote the courage to climb the peak of the revolutionary spirit of Chairman Mao glittering philosophy as a weapon, grasp the main contradictions, repeated practice, to overcome the difficulties of sand casting a road, so that the passing rate of casting stability increased to 95% or more , And the surface finish is as good as die-casting.
