Which blanking process sheared the sheet metal in three type of force separately applied.
Fine blanking sheet metal.
It is also similar to stamping but differs in the sense that it uses two opposing dies to form the gear from sheet material.
The tooling of fine blanking clearance will affect the final stamped part burrs height.
Fine blanking ensure stability regarding production with high quality and precision.
Sheet metal blanking process fine blanking process.
It ranges from 0 0003.
The fine blanking provides parts having smooth edge better flatness and high tolerance.
Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry.
Sheet thickness varies from 0 1 mm up to 12 mm and width up to 350 mm.
Fine blanking uses a specialized metal stamping press that provides equal pressure from both top and bottom on the metal sheet to produce flat edges by cutting the periphery in one stroke.
Fineblanking is a specialty type of metal stamping that can achieve part characteristics such as flatness and a full sheared edge to a degree that is nearly impossible using a conventional.
Fine blanking is a fully automated precision metal working stamping process.
Hope the following picture of a stamping factory experience will help you understand what is fine blanking and what difference between fine blanking and common punching and blanking process for sheet metal parts.
Fine blanking is a high precision type of blanking which is the die cutting of the outside shape of a part.
The working principle fine blanking of a typical spur gear is presented in fig.
Figure 1 when a punch makes contact with the sheet the metal begins to deform and bulge around the point of the punch.
