【高压油缸】大型油缸——镜面滚压刀




大型油缸——镜面滚压刀
  油缸是工程机械最主要部件,传统的加工方法是:拉削缸体——精镗缸体——磨削缸体。采用滚压方法是:拉削缸体——精镗缸体——滚压缸体,工序是3部分,但时间上对比:磨削缸体1米大概在1-2天的时间,滚压缸体1米大概在10-30分钟的时间。投入对比:磨床或绗磨机(几万——几百万),滚压刀(1仟——几万)。滚压后,孔表面粗糙度由幢滚前Ra3.2~6.3μm减小为Ra0.4~0.8μm,孔的表面硬度提高约30%,缸筒内表面疲劳强度提高25%。油缸使用寿命若只考虑缸筒影响,提高2~3倍,镗削滚压工艺较磨削工艺效率提高3倍左右。以上数据说明,滚压工艺是高效的,能大大提高缸筒的表面质量。  

 油缸经过滚压后,表面没有锋利的微小刃口,长时间的运动摩擦也不会损伤密封圈或密封件,这点在液压行业特别重要。


The cylinder is the most important component of the construction machinery. The traditional processing method is: broaching the cylinder block - boring block - grinding the cylinder block. The rolling method is: broaching - fine boring cylinder - rolling cylinder cylinder, the process is part of the 3, but the time contrast: 1 meters grinding cylinder in about 1-2 days, the rolling cylinder 1 meters in about 10-30 minutes. In contrast: grinder or article mill (tens of thousands of millions --), rolling knife (1 thousand - tens of thousands). After rolling, the hole surface roughness from a roll before Ra3.2 ~ 6.3 m reduced to Ra0.4 ~ 0.8 m, the hardness of the surface hole is increased by about 30%, the surface fatigue strength of the cylinder is increased by 25%. The service life of the cylinder can be increased by 2~3 times only if the cylinder is taken into consideration, and the grinding and rolling process can be improved by about 3 times as compared with the grinding process. The above data show that the rolling process is efficient and can greatly improve the surface quality of the cylinder.
When the cylinder is rolled, there is no sharp edged blade on the surface, and a long time of friction will not damage the sealing ring or seal. This is especially important in the hydraulic industry.
