Abstract Fine-blanking is a hybrid metal forming process that combines the technologies of stamping and cold extrusion. This article describes the three principal design features of the fine blanking process: the vee-ring, clearance between punch and die, and counterforce imposed by the ejector.

Fine Blanking of Helical Gears
2015Fine blanking is a well-established process for the production of near net shape components with high quality. The produced parts are characterized by a smooth sheared edge up to 100 %, excellent surface properties with good flatness and little burr as well as close tolerances for near net shape manufacturing. These process characteristics are suitable

A novel fine-blanking approach
The International Journal of Advanced Manufacturing Technology, 2014This paper proposes a novel approach to fine blanking. The V-ring indenter used in conventional fine blanking is no longer required; a trough on the die is used instead. In this approach, the cutting process combined with high hydrostatic stresses produced from the trough on the die cutting edge can substantially decrease the fracture in the shear zone.

Influence of Sheet Metal on Fine-Blanking Process
Materials and Manufacturing Processes, 2009A force that acts on the punch during fine-blanking of parts to be used in turbochargers for automotive diesel engines was measured. The aim of the research was to define the time dependence of the force and vertical movement of the punch at the same time.

Bacol make fine blanking a fine art
Industrial Lubrication and Tribology, 1978FINE blanking, the process of producing finished precision metal parts at one stroke of a press tool, is also a fine art so far as Bacol Industries Ltd are concerned. The company, a member of the Metalrax engineering group, is based at Bromsgrove, Worcs, occupying the biggest of a series of new factories on the Aston Fields Industrial Estate.

Numerical simulation for fine-blanking—a new approach
Materials Science and Engineering: A, 2004Abstract This paper presents the numerical simulation of fine-blanking using the large deformation elasto-plastic finite element method (FEM). In this simulation, the finite element mesh is re-zoned when severe element distortion occurs, in order to facilitate further computation and avoid divergence.

FEM and ANN Analysis in Fine-Blanking Process
Materials and Manufacturing Processes, 2010Fine-blanking (FB) is an effective and economical shearing process that offers a precise and clean cutting-edge finish, eliminates unnecessary secondary operations, and increases quality. In the traditional blanking product development paradigm, the design of the formed product and tooling is usually based on know-how and experience, which are ...

Numerical Simulation of Fine Blanking on Plane Blankholder
2010 International Conference on Digital Manufacturing & Automation, 2010Fine blanking process on plane blank holder utilizes three tooling elements: a punch, a plane blank holder and an ejector to generate a highly compressive stress state and pure shearing forces to constraint the deformation of sheet metal within the narrow blanking clearance zone.

Fine Blanking of Steel and Nonferrous Plates
1996The quality of cutting surface is measured depending upon the percentage of carbon and material structure. Examples from the following three groups of materials have been examined: carbon steel plates with a low percentage of carbon unalloyed carbon steel plates (0,19%C) alloyed carbon steel plates (0,48%C).
