Aluminum Sheet Drawing Process Defects

Defects In Sheet Metal Drawing - Me

Sheet metal drawing is a more complex operation than cutting or bending operation, and more things can go wrong during sheet metal drawing. A number of defects can occur in a sheet metal drawn product. Following is a list of common defects during sheet metal operation, with sketches are shown in Figure

Common Defects And Causes Of Sheet Metal Stamping

The following is an introduction to common defects and their causes in the sheet metal stamping process. 1. Blanking, punching, trimming. Defects: excessive burrs, deformation, surface scratches, size inconsistencies, few holes, etc. 1) The burr is too large → the gap between the convex and concave die is too large or too small; the cutting

NUMERICAL AND EXPERIMENTAL STUDY OF SHEET

  Sheet metal forming is a technique by which most body parts are produced in automobile industries. In sheet metal forming, a thin blank sheet is subjected to plastic deformation using forming tools to confirm to a designed shape. During the process, the blank sheet is likely to develop defects if the process parameters are not selected

Deep Drawing Process - State Of The Art And

  Deep drawing is a complex forming process, in which the sheet metal is drawn into a forming die by a punch, so that a different kind of stresses are applied on the material blank.If the depth of the part is greater than its diameter, the operation is considered to be deep. This can be reached by a redrawing of a part using a series of dies or press
