Move

from Wikipedia, the free encyclopedia
Process principle of shifting, on the left with one-sided restraint, on the right with two-sided. The workpiece is shown in green, the clamping device in gray and the tool in brown.

The displacement is a manufacturing method , which together with the rotation of the group of the thrust reshaping counts, in turn, to the main group of the reshaping counts. When moving, parallel, adjacent cross-sections of the workpiece in the deformation zone are shifted against each other, whereby they remain parallel, while they are no longer parallel when bending . The movement of the tool is straight.

Moving is suitable for both sheet metal and solid workpieces.

In the standard variant, one side of the workpiece is clamped and moved by one or more tools at a short distance from it. The forming takes place primarily in the gap between the clamping and the tool; however, the forming zone can also extend far below the tool. If the gap is too small, the material is overloaded and breaks like with shear cutting . The two methods are also used in combination.

In the case of solid workpieces, we also speak of enforcing . This is mainly used for the production of crankshafts : The cranks in the crankshaft are made from a straight, rod-shaped blank (often a square) by means of penetration. In the case of multi-stroke shafts, the individual crank webs are manufactured in one plane and then further processed by the related turning.
