对于品种多批量小的模锻生产来说,能否简便而快速地更换不同规格的模夹体是提高生产效率、保证锻件质量的关键。我厂3吨模锻锤主要是锻造机床齿轮类回转形锻件,采用了两种不同规格的镶块模,由于模夹体在加工时各部位存在着偏心差,这样就不可能事先确定定位块的精确尺寸。过去我们是采取锻造试样的办法,根据试样的偏心程度,在活动
For a large number of small batch forging production, the ability to simply and quickly replace the different specifications of the body is to improve production efficiency, the key to ensure the quality of forgings. I plant 3 tons die forging hammer is mainly forged gear forging machine tool forging, using two different specifications of the insert die, due to mold clamping body in the various parts of the existence of eccentricity, so it is impossible to determine the positioning block The exact size. In the past we used to forging the sample approach, according to the degree of eccentricity of the sample in the activity
