在全国工业学大庆会议精神鼓午下,我厂会同烟台市机械局、科研所组织以工人为主体的三结合试验小组,经4个月的奋战,用低熔点合金先后试制出了拉伸、弯曲、冲孔、切边、活动弯形和拉伸、切边复合模共10套,并投产使用,效果良好。冲孔、切边和拉伸切边复合模的结构,是根据镶拼式钢结构冷冲模,具有制造简单、容易锻造和热处理,并便于采用成型磨削工艺的特点,结合低熔点合金具有易于成型,且无收缩的基本特点,采用低熔点合金定位、支撑
In the spirit of the National Industrial Daqing Conference Drum, I plant with the Yantai Municipal Bureau of Machinery, Institute of workers organized by the workers as the main three combined test group, after 4 months of hard work, with low melting point alloy has trial-produced a stretch, Bending, punching, trimming, bending and stretching activities, trimming a total of 10 sets of mold, and put into operation, the effect is good. Punching, trimming and drawing trimming composite die structure, is based on the mosaic die-casting steel structure with simple manufacturing, easy forging and heat treatment, and easy to use molding grinding process characteristics, combined with low melting point alloy with easy Molding, and no shrinkage of the basic characteristics of low melting point alloy positioning, support
