据贵阳标准件一厂近年的统计资料表明,该厂M8螺母挤六方模具寿命最低,其消耗费用占全厂模具1/10,因此提高M8螺母镦挤模具寿命具有很大的技术经济价值。模具寿命跟所使用的设备精度有关。为了得到新旧模具寿命的比较,我们在同一台设备上试模(此设备和送料装置保持原有的几何精度),其新模具使用寿命显著提高。其中六方模芯使用寿命提高8倍,挤六方上
According to the statistical data of Guiyang Standard Parts Factory in recent years, it shows that the M8 nut of the factory has the lowest lifespan of squeezing the six-part mold and the cost of the mold occupies 1/10 of the whole mold. Therefore, it is of great technical and economic value to increase the life of M8 nut upsetting and extruding dies. Mold life depends on the accuracy of the equipment used. In order to get a comparison between old and new mold lifetimes, we tried on the same equipment (the original geometry accuracy of the equipment and feeders) and significantly improved the service life of the new molds. One six-way core life increased by 8 times, crowded six parties
