Manufacturing of Shaped Holes into Stamped Metal Sheet
 Bartusek, Břetislav ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The aim of bachelor thesis is a proposal of a new technology for manu-facturing of shaped holes into stamped metal sheets. The sheets are made of stainless steel DIN 1.4301 of thickness 0.8 mm. Square holes will be punched into a half-finished metal sheet with pre-pressed lengthwise stamps where elastic-plastic deformations occur. On the basis of study of the sheet metal forming technology, technological calculations and the machine adaptation, a new technology is proposed. The new technology is unassuming both with respect to machinery and tool equipment in a mechanical engineering factory. Also it enables solutions of dimensionally variable die stampings with stamps in higher quality for minimum costs. As the forming machine a punching press, model LDR 25-A, was chosen.
