Fine Blanking Process Sheet Metal

Fine blanking enables the production of high precision parts by non cutting cutting and if desired simultaneous forming.

Fine blanking process sheet metal.

Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry. Fine blanking is a fully automated precision metal working stamping process. Fine blanking ensure stability regarding production with high quality and precision. Blanking produces the outside features of the component while piercing produces internal holes or shapes.

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. It is also similar to stamping but differs in the sense that it uses two opposing dies to form the gear from sheet material. Blanking is a metal fabricating process during which a metal workpiece is removed from the primary metal strip or sheet when it is punched. Fine blanking permits 3 d composite processing including coining semi shearing bending and drawing.

Figure 1 when a punch makes contact with the sheet the metal begins to deform and bulge around the point of the punch. Sheet metal blanking process fine blanking process. It ranges from 0 0003. The material that is removed is the new metal workpiece or blank.

Fine blanking is a high precision metal forming process used extensively in the automotive heavy duty electronics medical lawn and garden and general industrial industries. The sheet metal extrusions in fine blanking sme fb advantages over a conventional extrusion are possible due to a blank holder force a counterpunch force and a large die radius. Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Home metal fabricating tips facts blanking process.

This post processing can be dispensed with if the sheet metal parts are finely cut. Most of the equipment and setup for fine blanking is similar to conventional. Punch direction press counter punch force compressive stress. Fine blanking process is one the specialize type of process.

The working principle fine blanking of a typical spur gear is presented in fig. Image courtesy of dayton progress. The web is created after multiple components have been produced and is considered scrap material. Different from normal.

If the finished part is to later have exact right angled cut edges it must be reworked.
