Manufacturing of kitchen sink
Vágner, Lukáš ; Peterková, Eva (referee) ; Jopek, Miroslav (advisor)
The project deals with the design of production of the kitchen sink made of chromium-nickel austenitic steel 1.4301. Material thickness of the sink is 1 mm. The annual production series is 30,000 pieces. After considering the size of the produced series, a combination of shearing and deep drawing was chosen as the production technology. Shearing of the circular shape was combined with the execution of both draws into one production tool. For this design, the necessary calculations were performed along with verification by simulations in the PAM-STAMP program.The tool is clamped in a hydraulic press PO 400, which has all the necessary parameters. The coil blank is guided through the unwinding and straightening device Compact Line GLK3-1000. The selling price of one sink was set at CZK 1,300. Production becomes profitable after producing 7540 sinks.

Design production of sink
Pecha, Oldřich ; Dvořák, Milan (referee) ; Podaný, Kamil (advisor)
Thesis submits concept of the sink fabrication technology where circular sink is made from rustproof austenitic steel 1.4301 (X5CrNi 18-10) using technology of conventional deep drawing without reducing wall’s thickness. Hydraulic press YL32 - 400 with nominal force 400 kN has been chosen as the production machine. Drawing tool with holder was designed to be used for this technology and its drawing documentation had been enclosed in this thesis. Size of the production series was set for 20 000 products annually. Control simulation of the drawing process has proven that designed component can be made and that computations are correct. Economic and technological estimation was performed which resulted in price being set for 555 czech crowns per piece. After manufacturing first 7 447 products the manufacturing process will become economically profitable.

Production of a corner sink
Soldán, Josef ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
This diploma thesis if focused on the production of a corner sink from stainless steel sheet 1.4301. Based on analysis of manufacturing possibilities the best solution is to produce corner sink by a conventional tool in serval operations, which was the main focus of theoretical part of this thesis. In addition, this choose is in conform with assignment of this diploma thesis. Practical part of this thesis was focused on check of technologicity followed with design of suitable shape of sheet for deep drawing. Further calculation of amount of required draws in specific drawing operations, calculation of drawing forces and works and calculation of parameters of drawing tool. These calculations were checked by numerical simulation which discovered possible defects whereupon the shape of corner sink was modified in order to limit these defects. Based on these calculations the universal drawing tool was designed. In the ending of this thesis the techno-economic evaluation was made which confirmed the economic advantage of this universality.

Production concept of sink
Bahula, Jan ; Jopek, Miroslav (referee) ; Císařová, Michaela (advisor)
The thesis presents a design for manufacturing a rotary kitchen sink made of a stainless austenitic steel 17 240 with a thickness of 0.8 mm with a production series of 20 000 pieces per year. Based on the analysis of manufacturing variants and necessary calculations, deep drawing without a reduction in the thickness was selected to three operations including calibration. A hydraulic press PO 250 from Dieffenbacher was chosen based on the required forces and available rams. The drawing process was checked using numerical simulations and tools were designed for each operation using a drawing ram, a bottom blank holder, and an upper ejector. In the design of drawing tools, normalised components or easily manufacturable parts were preferred.
