我厂在加工60克注射机油缸时,因孔径尺寸大(直径160~(+0.04)毫米,深400毫米),缸壁要求达▽9,表面且有一定的硬度要求,不论设备和工艺上都存在一定困难。后来根椐兄弟单位滚压加工经验,自制了图1所示的滚压工具,使油缸内壁加工光洁度达▽8～▽10,表面硬度达HRC40以上,满足了生产需要。 I plant processing 60 grams injection machine cylinder, due to the large aperture size (diameter 160 ~ (+0.04) mm, 400 mm deep), cylinder wall requirements up to ▽ 9, the surface and have a certain hardness requirements, regardless of equipment and processes There are some difficulties. Later, according to Brother’s unit rolling processing experience, self-made roll tool shown in Figure 1, the tank wall finish of ▽ 8 ~ ▽ 10, the surface hardness of HRC40 or more, to meet the production needs.
