Fine Blanking Process Sheet Metal

Fine blanking is a fully automated precision metal working stamping process.

Fine blanking process sheet metal. Sheet metal blanking process fine blanking process. It ranges from 0 0003. Characteristics of the blanking process include. Fine blanking ensure stability regarding production with high quality and precision.

This post processing can be dispensed with if the sheet metal parts are finely cut. Different from normal. 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. Blanking is a metal fabricating process during which a metal workpiece is removed from the primary metal strip or sheet when it is punched.

The web is created after multiple components have been produced and is considered scrap material. The fine blanking provides parts having smooth edge better flatness and high tolerance. Home metal fabricating tips facts blanking process. Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock.

The working principle fine blanking of a typical spur gear is presented in fig. 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. Which blanking process sheared the sheet metal in three type of force separately applied. Punch direction press counter punch force compressive stress.

Most of the equipment and setup for fine blanking is similar to conventional. Blanking produces the outside features of the component while piercing produces internal holes or shapes. If the finished part is to later have exact right angled cut edges it must be reworked. The material that is removed is the new metal workpiece or blank.

Figure 1 when a punch makes contact with the sheet the metal begins to deform and bulge around the point of the punch. 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 permits 3 d composite processing including coining semi shearing bending and drawing. Fine blanking enables the production of high precision parts by non cutting cutting and if desired simultaneous forming.

Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry.
