我厂长期生产纸机零配件,并修复胶辊断轴等配件,原承接用户胶辊断轴修复采用轴与孔红装,因而不能保留原胶面。近年来,受用户的委托,采用轴与孔过盈配合冷压工艺,取得了成功。现将1092、1575纸机的胶辊断轴修复方法介绍如下: 一、将胶辊紧固在T68镗床工作台上,为保护胶辊胶面,采用弧型压铁紧固的方法,弧型压铁内衬有橡胶其厚度为5mm,硬度A=75°±3°。先钻孔,镗孔去掉原断轴部分(使用浮动镗刀,冷却液用煤油)。内孔光洁度达▽7,精度2级。并用百分表测出内孔的准确尺寸。二、加工一根新轴,经热处理调质后,将装配长度部分粗车(按镗孔尺寸配做)并留0.4～0.5mm磨量,过
I plant long-term production of paper machine spare parts, and repair roller broken shaft and other accessories, the original user to undertake the broken roller shaft and hole repair red, and therefore can not retain the original plastic surface. In recent years, commissioned by the user, the use of shaft and hole interference with cold pressing process, and achieved success. Now 1092,1575 paper machine roller broken shaft repair methods are described below: First, the rubber roller fastened T68 boring machine table, in order to protect the rubber roller rubber surface, the use of arc-type iron fastening method, arc Iron lined with rubber thickness of 5mm, hardness A = 75 ° ± 3 °. First drilling, boring to remove the original broken shaft part (using a floating boring knife, coolant with kerosene). Inner hole finish up to ▽ 7, accuracy of 2 levels. And use the dial indicator to measure the exact size of the hole. Second, the processing of a new shaft, after heat treatment quenched and tempered, the assembly of the length of the rough car (according to the size of boring made) and leave 0.4 ~ 0.5mm grinding, too
