六角螺母是各种机器中不可缺少的零件。我厂制造的各种压缩机上六角螺母的需要量很大。一般小六角螺母,我们用六角钢材制造;大六角螺母我们用圆钢在牛头刨床上刨成六角形。但是过去一直是用一块压板把圆钢压牢在刨床工作台上,用单刀加工,这样刨一根圆钢时间很长,远远跟不上需要。刨工李文沼同志改进了刨六角形用的夹具,同时采用双刀进行刨削,缩短了机动时间,提高了生产效率。 Hex nuts are indispensable for all kinds of machines. I plant a variety of compressors hex nuts on the great demand. General small hex nut, we use hexagonal steel; large hexagonal nut we use bar in the shaper planing hexagonal. However, in the past, the round steel was pressed firmly on a planer table with a pressure plate, and was processed by a single-piece knife. In this way, planing a round steel took a long time and could not keep up with the need. Planer Li Wenmang comrades improved sharpening hexagonal fixture, while the use of double-pole shaving, shorten the maneuver time and improve production efficiency.
