中高率辊筒是橡胶、塑料薄膜工业生产设备中常见的一种关键零件.其曲率辊面的最终加工,通常是由专用的曲率磨床来完成的.由于这种设备的专用性强、设备投资费用也高,目前在机械制造行业中配备的数量也极为有限.我厂在生产 SY4F-1120A 型四辊压延机时,对其中的中高率辊筒磨削,采用了一种新颖的靠模机构,在 M1350普通外圆磨床上,完成了辊面的曲率磨削,质量达到了设计要求。SY4F-1120A 型四辊压延机辊筒的馄面材料是冷硬铸铁,硬度为 HS68～75,辊筒的曲率辊面尺寸为φ360×1120mm,工件全长2230mm,重800kg,,一组辊筒的辊面曲率分别为0.04、0.06、0.08mm,表面
Medium and high rate of roller rubber and plastic film industry production equipment is a common key parts of the curvature of the surface of the final processing, usually by a dedicated curvature grinder to complete.Because of the special equipment, investment in equipment The cost is also high, the current number of machinery manufacturing industry is also equipped with a very limited number of our plant in the production of SY4F-1120A four-roll calender, which one of the high-rate roller grinding, using a novel by the mold agencies , In the M1350 ordinary cylindrical grinder, the completion of the curvature of the roller grinding, the quality of the design requirements. SY4F-1120A-type four-roll calender roll ravioli surface material is chilled cast iron, hardness HS68 ~ 75, the roller surface roller size of the size of φ360 × 1120mm, the entire length of 2230mm, weight 800kg ,, a group of rollers The roll surface curvature was 0.04,0.06,0.08mm, the surface
