我厂以前生产螺母,都是用小汽锤或手工锻制的,每炉起码要4人,每8小时最快只能生产3/4″的螺母350件,而且每件的外形尺寸误差比较大。尤其是内孔的位置容易锻打偏移,所以孔的加工余量就留得大一些,浪费了机械加工工时和材料。我厂锻压工段针对以上情况,经过班长同志研究,并在技术员配合下,把比较小的螺母由锤锻改在摩擦压力机上压制;这样产品质量不但良好,而且产量据统计每8小时可以生产700～800件,操作工人由4人改为2人就行。因此按劳动生产率计,在压力机上制造比手工或小汽锤锻造可以提高3倍以上。
I used to produce nuts in our factory, all of them are made of small hammer or hand forged, at least 4 people per furnace, and only 350 pieces of 3/4 "nuts can be produced as fast as every 8 hours, and the error of the outline size of each piece is compared Large, especially the location of the hole easily forged offset, so the hole allowance to stay larger, wasted mechanical working hours and materials.For our plant forging the above situation, after the monitor gantry and technician With the cooperation of the smaller nuts by hammer forging on the friction press to suppress; this product quality is not only good, but the output according to statistics every 8 hours can produce 700 to 800, the operator from 4 to 2 on the line. In terms of labor productivity, making presses on a press can be more than three times greater than forging by hand or hammers.
