冷拨钢管用园柱形顶头在镀铬前应去掉两端面上热处理淬火后的氧化皮,以利于镀铬时导电,而顶头的园柱面也应抛光,以增加镀层的附着能力。长期以来,顶头的这两道光整工序都是采用手工操作。对于大直径顶头通过手工光整,不仅劳动强度大,消耗材料多,而且因为工效低,往往不能满足大生产需要。我厂分厂机修车间职工刻苦研究,试制成功大直径顶头光整设备,有效提高了光整工作效
Cold dial steel pipe with a cylindrical head in the chrome should be removed before the heat treatment of both ends of the quenched oxide skin, in order to facilitate the conductivity of chrome, while the head of the cylindrical surface should be polished to increase the coating adhesion. For a long time, the head of these two finishing processes are used by hand. For large diameter head by hand finishing, not only labor-intensive, consume more material, and because of low efficiency, often can not meet the needs of large-scale production. I plant plant mechanic shop workers study hard, successful trial of large-diameter head finishing equipment, effectively improve the efficiency of finishing
