| titleOfInvention | Manufacturing Method of Thread Shape Hydraulic Cylinder Block |
| abstract | The present invention relates to a method for producing a thread-shaped hydraulic cylinder block, in particular, 0.5% carbon (C), phosphorus (P) 0.45%, iron sulfide (FeS) 1.0 by weight ratio of the raw material of iron (Fe) as the main raw material powder Mixing a powder mixture for preparing a hydraulic cylinder block by mixing% to 10% and 1.0% of a binder; Selecting a molding process that minimizes the density gradient and exceeds a required density through a powder compression molding process finite element analysis of the powder mixture prepared in the powder composition step; Injecting the powder mixture prepared in the powder composition step into a mold of a hydraulic cylinder block having a specific shape; Molding the mold into which the powder mixture is injected into a mold under a molding condition selected in the finite element analysis molding process selecting step to mold a molded body of a hydraulic cylinder block having a specific shape; And a step of heating and sintering a molded body of the hydraulic cylinder block of the specific shape, which is compression-molded under a specific sintering temperature condition. |
