3D Solid Modeling

This paper introduces motor rotor blanking die design process through specific terms of the process of stamping all. Mould design process is for structural analysis and process analysis of the parts diagram, based on it to determine the technology methods, select the structure of the mould, and make a necessary calculation to determine stock layout and the size of the work part. And choose a suitable punching machine. Finally, choose the parts from the manual of mould.This design also includes the use of AutoCAD software mapping die assembly and major parts map using UG and Pro/E software for 3D solid modeling and animation design simulation process. In addition, the punch and die processing choose WEDM and Programming. So consider the structural design of WEDM of the specific methods to avoid the conflict between design and processing, and guarantee the production reasonable.

Extrudate Distortion

Abstract A combined flow, thermal and structural analysis is employed to simulate post-die extrudate distortion in different profile dies. All four factors which can cause extrudate distortion, namely, nonuniform exit velocity distribution, extrudate shrinkage, extrudate draw down, and deformed shape of the calibrator or sizer profile, are simulated. To analyze the effect of exit velocity variation on extrudate distortion, the parameterized geometry of a simple profile die is optimized using an extrusion die optimization software. The simulation results presented for a bi-layer profile die successfully demonstrate how gradually changing profile shape in successive calibrators/sizers can be used to simplify the die design for extrusion of complex profiles. The predicted extrudate shape and layer structure for the bi-layer die are found to accurately match with those in the extruded product.

Semi Solid

Semi-solid slurry has significantly higher viscosity than liquid metal. This character of fluidity makes product design and die design, such as gating system, overflow and venting system, be different between these two die casting processes. In the present paper, taking a clamp product as an example, analyses the product optimization and die design by comparing the experimental and computational numerical simulation results. For the clamp, product structure is designed to be suitable for characters of SSM die casting process. The gating system is designed to be uniform variation of thickness, making the cross-sectional area uniformly reduce from the biscuit to the gate. This design ensures semi-solid metal slurry to fill die cavity from thick wall to thin wall. Gate position is designed at the thickest location, the gate shape of semi-solid die casting is set to be much bigger than traditional liquid casting. A good filling behaviour can be achieved by aforementioned all these design principles and it will be helpful to the intensification of pressure feeding after filling.
