链环钩是联合卸煤机中的一只易损件。由于损耗大,每年需要加工几百件备件。开始时采用手工弯制链环钩,很难达到图纸形状尺寸,而且操作繁锁,劳动强度大。针对上述情况,进行了认真研究,通过反复试验,制成了摆块式弯模,来生产链环钩。 1.锻件工艺分析链环钩锻件图如图1所示。材质45号钢,坯重0.76kg,此锻件形状近似“U”类弯曲件。为了达到一次弯曲成形,参照有关资料和试
Chain hooks are a consumable part of a coal unloader. Due to large losses, hundreds of spare parts are processed each year. The beginning of the use of manual bending chain hook, it is difficult to achieve the shape and size drawings, and cumbersome operation, labor-intensive. In view of the above situation, conducted a careful study, through trial and error, made of pendulum block bending mold, to produce chain hook. 1. Forgings Analysis of the chain hook forgings Figure 1 shows. Material 45 steel, billet weight 0.76kg, this forgings shape similar to “U” type bending pieces. In order to achieve a bending forming, with reference to the relevant information and test
