我厂全年要为制造深井泵生产6.2万个法兰盘。用钢板切割法兰盘,浪费 2/3钢材,且汽割下来的毛坯硬度增高,给切削加工造成困难;采用自由锻加工法兰盘,虽然材料的利用率有所提高,但生产率低,成本高,每吨需加工费达七百元。我厂锻工组全体同志在厂各级党组织的领导下,敢想敢干,利用废旧材料,在兄弟车间的大力协助下,经过不断实践、改进,试制成功一台结构简单体积小的冷卷法兰盘机,生产出合格的法兰盘毛坯。冷卷法兰盘是一种少、无切削新工艺,采用扁钢作原料,经过冷卷、切削、热乎、焊接即可得到法兰盘毛坯制品。冷卷比自由锻造提高工效5～6倍;同
Our factory produces 62,000 flanges for manufacturing deep well pumps all year round. Steel plate cutting flange, wasting 2/3 of steel, and the steam cut the rough hardness of the rough, resulting in difficulties in cutting; using free forging flange, although the material utilization has improved, but the low productivity, cost High, processing fee per ton up to 700 yuan. Under the leadership of the party organizations at all levels of the factory, all the comrades of our factory work hard to make use of the waste materials. With the help of the sibling workshop, through the continuous practice, improvement and trial production, we succeeded in successfully building a small, Volume flange machine to produce qualified flange blank. Cold-rolled flange is a less, no cutting new technology, the use of flat steel as raw material, after cold roll, cutting, heat, welding can be obtained flange blank products. Cold forging than free forging to improve efficiency 5 to 6 times; the same
