Metamorphic Vibration Casting Process And Equipment Of Complex Steel Castings

Casting is the foundation of modern machinery manufacturing technology, performance and quality of the casting marks the level of the national industry.In recent years, with the continuous innovation of industrial technology, the traditional sand casting process is difficult to meet the needs of modem industry, casting CAE and vibration application of technology can significantly reduce the casting defects and improve the mechanical properties of castings, reduce product design cycle time and labor costs, thus achieving the advantages of improving the quality of castings and industrise competitiveness.This article summarizes the numerical simulation of casting and vibration technology Casting research status process and the status of Parallel Metamorphic Mechanism overview. Simulation analysis the process of steel castings investment cast by using ProCAST, and on this basis, a parallel Metamorphic vibration casting machine been designed to meet different vibration parameters of shape. The main contents are as follows:According to the characteristics of marine structures and steel castings high manganese steel stent, designed two different casting system, drawn two kinds three-dimensional images of casting system, simulation of investment casting process by using ProCAST, and analysis of the filling and solidification process.Based on orthogonal test, the optimal parameters of the selected combination regimen.Using EDEM coupled with FLUENT simulation solid-liquid molten metal particles to study the effect vibration metamorphic process on the filling process, through the image display state of motion of particles in the filling process, it reached a different vibration conditions influence on the particle, the use of orthogonal test results within the study area the number of particles filling the sensitivity of the degrees of freedom, frequency and amplitude.Based on the theory of parallel mechanism, designed a three translational parallel Metamorphic vibration casting machine, with 2-PRRR parallel mechanism as the main principle of screw theory to analyze 1he degree of freedom, then the trajectory calculated based on the vibration platform DH matrix, thereby seeking It was Jacobian matrix, obtained the agency produces singularity conditions and using ADAMS software to analyze the nature of sports caster vibrating parallel Metamorphic different vibration parameters under.Through the first generation of three-dimensional parallel casting machine working defect analysis, based on TRIZ Optimal Design of Parallel Metamorphic vibration casting machine, according to the original parameters of the prototype, using ANS YS respectively base and vibration chain designed Metamorphic vibration casting machine modal analysis and fatigue analysis, to improve the processing of reference for the prototype.
