套筒厂家之滚丝机

在滚丝机(ji)上冷轧(ya)(ya)加工(gong)(gong)(gong)螺纹(wen)原理是小模数渐开线花(hua)键的(de)(de)(de)原理。L、R是参数相(xiang)同(tong)的(de)(de)(de)一对(dui)渐开线滚轧(ya)(ya)轮(lun),分别安装在滚丝机(ji)的(de)(de)(de)两根主轴(zhou)上,并可(ke)(ke)(ke)在传动(dong)(dong)机(ji)构(gou)(gou)的(de)(de)(de)驱动(dong)(dong)下同(tong)向(xiang)(xiang)同(tong)步旋(xuan)转。R轮(lun)可(ke)(ke)(ke)由油缸驱动(dong)(dong)进行径(jing)向(xiang)(xiang)进给(ji)运动(dong)(dong),L轮(lun)可(ke)(ke)(ke)通过调(diao)(diao)整(zheng)机(ji)构(gou)(gou)的(de)(de)(de)调(diao)(diao)整(zheng)与R轮(lun)在工(gong)(gong)(gong)件(jian)P表面的(de)(de)(de)压痕重合。工(gong)(gong)(gong)件(jian)P以(yi)两孔定位(wei)夹(jia)紧,调(diao)(diao)整(zheng)夹(jia)具可(ke)(ke)(ke)使工(gong)(gong)(gong)件(jian)轴(zhou)向(xiang)(xiang)移(yi)动(dong)(dong),在受力时(shi)可(ke)(ke)(ke)绕夹(jia)具上过O点与机(ji)床主轴(zhou)平行的(de)(de)(de)轴(zhou)线摆动(dong)(dong)一个Φ角,以(yi)保(bao)证工(gong)(gong)(gong)件(jian)在冷轧(ya)(ya)过程中始终保(bao)持与两滚轧(ya)(ya)轮(lun)处于(yu)自由对(dui)滚状(zhuang)态,同(tong)时(shi)便于(yu)装夹(jia)工(gong)(gong)(gong)件(jian)。滚轧(ya)(ya)轮(lun)的(de)(de)(de)结构(gou)(gou)尺(chi)寸、形(xing)位(wei)公(gong)(gong)差及(ji)技术要求参照(zhao)滚丝轮(lun)及(ji)圆柱测量齿(chi)轮(lun)制订,滚轧(ya)(ya)轮(lun)的(de)(de)(de)公(gong)(gong)法(fa)线长(zhang)度或跨棒距M按齿(chi)轮(lun)工(gong)(gong)(gong)中花(hua)键资(zi)料计算,所需材料可(ke)(ke)(ke)选用Cr12MoV(硬(ying)度59~62HRC)。
