Study on Making Process and Mould Structure of None-phase Angle Crankshaft with Four Cylinder Sleeve
According to the shape character of some one none-phase angle crankshaft,a production process characterized by direct final forging after making process was brought forward.Based on simulations the pre-form step was skipped through optimizing making process and mould structure.The results show that the forming impression of mould with common flash gutter works out badly,while linear pattern resistance wall could not solve filling problems.Whereas,the resistance wall following part achieves good simulation result.
