Analysis of Multi-Directional Squeeze Casting Liquid Forging of Sewing Machine Oil Chassis

Abstract:

Sewing machine oil chassis is manufactured by adopting the method of multi-directional squeeze casting liquid forging. When multi-directional pressure is applied on the template, forward and radial pressures inside the solidified body are the same at each direction according to calculation and analysis. The internal pressure inside the blanks is the same, and crystal growth rate and plastic deformation are consistent at each direction, therefore solidification tissue conformation of the cast during multi-directional squeeze casting liquid forging eliminates the defects of directional difference, uneven density, even looseness, cavity shrinkage and the like.
