Design of Kitchen Sink Production
 Dvořák, Ondřej ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The work deals with the design of technology to produce a circular kitchen sink with a narrow flange around the perimeter. The semi-finished product is a 0.8 mm thick stainless-steel sheet X5CrNi18-10. The size of the production series is set at 200,000 pieces per year. Based on a literature search, the technology of deep drawing without thinning the wall was chosen for the production. Then was the sink examined in terms of technology and method of production, which included determining the number of draws, calculating forces and work during forming and other calculations necessary to design a drawing tool. The result shows that to produce the final shape is required two drawing operations with a blank holder and production will be carried out on a hydraulic press HARSLE Y27-200T with a nominal drawing force of 2000 kN. For the first and second operation a drawing tool was designed, for which was prepared the relevant technical documentation. The punch, the die and the blank holder are made of tool heat-treated steel 19 436.9 and they are fixed in welded bodies of common structural steel 11 373. Using the simulation of a drawing was subsequently verified the accuracy of technological calculations and the suitability of the selected method of production.
