在制造大型冲模的上下模板、复杂夹具的主体及大型零件等,由于热处理后的变形,如果没有专用设备进行加工,在普通磨床上修磨内孔是比较困难的;这样,有时不仅影响到产品质量,而且延长了生产周期。在优质高产运动的新高潮中,我厂冲模车间工艺师胡代新同志,和镗工部老工人结合,针对上述关键,进行了分析研究,创制出了镗淬火钢内孔用的镗刀。
In the manufacture of large die of the upper and lower template, the main body of complex jigs and large parts, due to deformation after heat treatment, if there is no special equipment for processing, grinding in the ordinary grinder bore is more difficult, so sometimes not only affect the product Quality, but also extend the production cycle. In the new upsurge of high-quality and high-yielding movement, Hu Daxin, a technologist at the die-stamping workshop of our factory, combined with the old workers in the boring department, analyzed and studied the above key issues and created a boring tool for bore boring and hardened steel.
