Abstract
Official abstract text for this publication.
The invention relates to a device for drawing components from a blank ( 1 ) made of metal using a drawing punch ( 2 ) and a die ( 3 ), the drawing punch ( 2 ) having a cutting edge ( 4 ) for trimming the blank ( 1 ) during the drawing procedure and a run-in contour ( 5 ) being provided in the die ( 3 ). The invention also relates to a method for drawing a blank using the device according to the invention and to a use according to the invention of the method. The run-in contour ( 5 ) of the die ( 3 ) is configured such that the cutting edge ( 4 ) and the run-in contour ( 5 ) are only in cutting engagement in certain regions in the drawing punch position at the start of the cutting procedure along the cutting line ( 7 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. Device for drawing components from a blank made of metal comprising a drawing punch and a die, the drawing punch having a cutting edge for trimming the blank during a drawing procedure and a run-in contour being provided in the die, wherein the run-in contour of the die defines a cutting line and said run-in contour is configured such that the cutting edge and the run-in contour are only in cutting engagement in certain regions and not along the entire cutting line in the drawing punch position at the start of the cutting procedure along the cutting line defined by the die. 2. Device according to claim 1 , wherein the cutting edge of the drawing punch is simultaneously configured to form and compress a finished contour of the component. 3. Device according to claim 1 , wherein the run-in contour varies or is graduated along the cutting line. 4. Device according to claim 1 , wherein the run-in contour has a tooth-like or undulating profile along the cutting line. 5. Device according to claim 1 , wherein the cutting edge of the drawing punch is simultaneously configured to form a finished contour of the component. 6. Device according to claim 1 , wherein the cutting edge of the drawing punch is simultaneously configured to compress a finished contour of the component. 7. Device according to claim 1 , wherein the cutting edge is disposed in a plane perpendicular to the drawing movement of the drawing punch.
