灰盘材料是 QT50-5,外径为2840,在做低温石墨化处理时,工件发生了不规则翘曲变形,最大达50毫米,加工余量为15毫米,眼看价值一千多元的工件要报废,如何挽救呢?我们将灰盘放在炉中,压上一个大齿圈,以齿圈端面为基准。测量齿圈下端和灰盘间的间隙,如 A 处测得间隙为20毫米,则在灰盘下端面 A′处加垫一20毫米厚的铁板;B 处测得间隙为30毫米,则在
Gray plate material is QT50-5, the outer diameter of 2840, doing low-temperature graphitization, the workpiece irregular buckling occurs, the largest up to 50 millimeters, the machining allowance of 15 millimeters, seeing the value of more than one thousand yuan of the workpiece To be scrapped, how to save it? We will put the ash tray in the furnace, pressed on a ring gear, ring gear end as a benchmark. Measure the gap between the lower end of the gear ring and the gray plate. If the clearance measured at A is 20 mm, add a 20 mm thick plate of iron to the lower plate A ’of the gray plate. When the clearance measured at B is 30 mm, in
