Design of Stamping Drawing Technology from Thin Sheet

Popis výsledku v původním jazyce

The paper deals with the design of the technology for the production of the cover stamping to achieve the minimum cost of one piece of the produced component. By calculation, the minimum values of the radius of curvature of the edge of the draw die and the edge of the draw punch were determined to eliminate the calibration operation. The shape and dimensions of the blank for the cover stamping were determined by several methods and then compared. Simulations of the drawing process allowed the locations with the greatest thinning to be analyzed and the drawability of the stamping from each alternative of the blank shape to be verified. The results of the simulations showed the highest suitability of the blank determined by the Autodesk Inventor program and also by the BSE module in Dynaform. The simulation results further demonstrated the necessity to increase the radii of curvature of the drawing edge of both the draw die and the draw punch to a value of 4 mm, which allows the fabrication of a defect-free cover stamping without the need for subsequent calibration. The use of the simulation program in the technological preparation phase of production allowed one to optimise the drawing process by a suitable design of the shape of the blank and also allowed one to design a change in the shape of the stamping which eliminated the formation of cracks at its bottom during drawing.
