Cutting is the use of punching die so that part of the material or process with another part of the material, the labor,
Or waste separation of a stamping process.
Blanking is cut, blanking, punching, punching, cutting, notching, cut, cut, cutting, trimming, cutting tongue repair, such as the floorboard of the separation process.
Isolated from sheet metal on the required shape and size of the parts or stamping method of blank.
Blanking is to use the outline of die parts sheet along a certain line produce shear deformation and separation.
Cutting the proportion of the biggest in the stamping production.
In blanking process, in addition to the shear near the contour line of metal, sheet metal itself does not produce plastic deformation, so by the flat cutting machining parts is a flat shape.
Multistep blanking pieces with the arrangement of the single process when cutting (
Blanking billet and the strip material separation first, then punching or piercing.
The subsequent process of locating datum should agree to avoid position error and dimension chain conversion.
Cutting size is different, close distance between holes, should be washed after the big hole hole.
The arrangement of the continuous cutting (
First punch or gap, finally blanking or cut, blanking pieces will be separated from the material.
First rushed out of the hole of the positioning hole for subsequent working procedure.
Using distance side blade, distance side edge trimming process arrangement and punch for the first time at the same time, in order to control feeding into the distance.
Using two side edge distance, can be arranged in tandem.
