压弯卷圆半自动级进模具(图1)是一种深受冲压工人欢迎的级进模具,这套模具是我厂生产59型矿灯磁锁板零件用的,在改革前生产磁锁板需要四道工序(即下料,一次压弯,二次压弯,三次压弯),并且是手工送料,效率低,劳动强度大,容易发生工伤事故,革新后,增加了自动送料机构,一次下料一次压弯卷圆成形,减少了二道工序,提高生产效率5倍,并保证了工人的人 Semi-automatic progressive bending die bending (Figure 1) is a popular stamping workers welcomed the progressive die, the mold is my factory production of 59 Miner’slamp magnetic lock plate parts used in the production of magnetic lock before the reform needs Four processes (ie, blanking, bending once, twice bending, bending three times), and is manual feeding, low efficiency, labor-intensive, prone to accidents, after the renovation, an increase of automatic feeding mechanism, a Material bending a round shape, reducing the two processes, improve production efficiency 5 times, and to ensure that the workers of people
