随着机床自动化程度的不断提高,特别是在大批量生产中,越来越需要应用机械手来代替人工,这不仅可以减轻体力劳动,而且可以大大地提高劳动生产率,降低成本,节约原材料。我厂生产大批量的圆锥滚子,由于压力机运行的节拍时间很短,更迫切地需要采用机械手来代替手工劳动。过去,我厂生产圆锥滚子是用仪表车床车削的,班产只有400粒左右,不但生产效率低,材料浪费,成本高,质量也差。在毛主席“自力更生,艰苦奋斗”的伟大号召下,在轰轰烈烈的批林批孔运动的推动下,我厂学习了兄弟厂的好经验,在一百吨压力机上冲压圆锥滚子时采用机械手,生产效率可提高20倍左右,以7212轴承滚子为例,可节约原材料41.2％。机械手应用在一百吨压力机冲压圆锥滚子的原理可从下图予以说明。
With the continuous improvement of machine automation, especially in mass production, more and more need to use robots instead of labor, which not only can reduce manual labor, but also can greatly improve labor productivity, reduce costs and save raw materials. I plant a large number of tapered roller production, the press run time is very short, more urgent need to use mechanical hand instead of manual labor. In the past, I tapered roller factory production is the use of turning lathe, class production is only about 400, not only low production efficiency, material waste, high cost, poor quality. Under the great call of Chairman Mao’s “self-reliance and arduous struggle”, under the impetus of the vigorous operation of criticizing Lin and Piao Kong, our factory learned the good experience of Brother Factory and used mechanical hand when stamping tapered roller on 100-ton press, Production efficiency can be increased about 20 times to 7212 bearing roller, for example, can save 41.2% of raw materials. Manipulator used in a hundred tons of press stamping tapered roller principle can be illustrated from the following figure.
