过去,我们制造像图1那样条播种机开沟器支架,是用固定式弯型模在手扳冲床上进行,整个过程差不多都是靠手工操作,不消说效率低,连质量也不能保证。后来我们设计制造了一套回转式弯工件的模具,在80吨摩擦冲床上一次可以压制两个工件;一人烧火一人操作,每天能够压制1000件,提高效率10倍,还保证质量良好。 In the past, we made the opener opener bracket like the one in Fig. 1, which was done with a fixed bending die on the punch press. The whole process was almost entirely manual, not to mention the inefficiency, even the quality. Later, we designed and manufactured a set of molds for rotary bending workpieces, which can be used to press two workpieces at a time on a 80-ton friction punch. One person can burn 1000 pieces per day to increase the efficiency by 10 times and ensure good quality.
