Finite element simulation of sheet fine blanking process
International Journal of Material Forming, 2009The metal sheet fine blanking process of a circular hole is simulated using a two-dimensional axisymmetric finite element model. A numerical model used in our computer simulation is based on a dynamic explicit scheme. Yield curve that is implemented in the numerical model is obtained upon tension test data. Its particularity is first the extension into

Materials Science Forum, 2011
The plastic analysis software DEFORM was used to simulate the blanking process of metal plastic without burr. Based on theory of the rigid FEM, the geometry model used for blanking with a negative clearance was established. The facts of influence the quality of the blanking work pieces were analyzed and concluded, at the same time, the parameters were ...

Numerical Investigation of Fine Blanking of a Helical Gear
Applied Mechanics and Materials, 2012Fine blanking, as an effective and economy metal forming process, can be used for the manufacturing of helical gears with inclined forming movement. In the present study, a reliable three-dimensional (3D) rigid-plastic finite element (FE) model is developed on the DEFORM-3D platform for rotational fine blanking of a helical gear. Based on this FE model,

Fine Blanking Small Caliber Weapon Parts
1978Abstract : The objective of this project was to investigate the feasibility of fine blanking small weapon components to close tolerances. Of particular concern was the applicability of the process to higher alloy materials. Eight parts which represented a variety of size, shape, thickness and material were selected.

Modelling of Fine Blanking Process of the Aluminium Sheets
Key Engineering Materials, 2011The required technological quality of the blanked products can be achieved through operations of fine blanking. This allows for obtaining products with improved dimensional accuracy and good quality cut-surface. In order to cut products from soft materials, including aluminium and its alloys, the methods of fine blanking with upsetting and fine ...

An improved ductile fracture criterion for fine-blanking process
Journal of Shanghai Jiaotong University (Science), 2008In order to accurately simulate the fine-blanking process, a suitable ductile fracture is significant. So an evaluation strategy based on experimental and corresponding simulation results of tensile, compression, torsion and fine-blanking test is designed to evaluate five typical ductile fracture criteria, which are widely-used in metal forming process.

A Study of Fine Blanking Process by FEM Simulation
Key Engineering Materials, 2004Fine blanking process with V-ring was simulated with FEM. The geometric parameters of the die, the punch, the serrated ring and the sheet are modeled. In this paper, some other assumptions are made for the analysis. The workpiece is considered as elastic-plastic material, while the tools are defined as rigid bodies. The damage model taking into account

Application of Back-Up Ring in Fine-Blanking Process
Key Engineering Materials, 2010Considering the advantages of the fine-blanking process, the smooth-cut surface without further operation could be fabricated. However, one of the major problems of the fine-blanking is the occurrence of the die-roll formation. This problem is the main factor which affects the quality of the fine-blanked parts.
