Abstract

The difficulty of force relations, workpiece deformation can be caused by a combination of factors. The most common method used in analyzing workpiece deformation and fixturing forces is by using ANSYS. Insufficient punch force will result to burr and tearing of the workpiece during the blanking and bending. Application of too much punch force also would result in unnecessary defects and high contact deformation to the workpiece. The aims of this project are to design a blanking and bending die and determine whether a blanking and bending is able to reduce burring and tearing in producing a thimble open small. By using Explicit Dynamic Analysis from ANSYS software, the result of the Finite Element Analysis for new design of blanking and bending die will be obtained. From the result, the maximum punch force of blanking and bending die is obtained which are 43.29x103N and 1.35x103N and able to reduce the defect on blanking and bending process to produce the thimble open small. As a result, the new design of blanking and bending die presents the shortest process of bend and blank in producing the thimble open small with highest productivity, lower cycle time, less manpower and lowest cost compared to existing design with the same value of punch force.
