The production of a component of a lever lock
Hráček, Josef ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The master‘s thesis deals with the suggestion of the production of a component of a lever closure, which is used as a quick-clamping mechanism. The part is made of low-carbon steel DC01 in the form of a sheet with a thickness of 1.5 mm and an annual production of 200,000 pcs. The individual production methods were chosen using a progressive combined tool that combines cutting and bending. After evaluating the technology, determining the developed shape of the part and choosing its location on the line was chosen a semi-finished product in the form of metal coils sheet. After determining the production procedure, which consists of four steps, technological, construction and control calculations were carried out on the basis of which the tool was constructed. An eccentric press LEN 63 C was chosen as a suitable machine for production. A feed line marked ARPL RAL 150 was also chosen for production.

Use of water jet technology in a company
Faltus, Tomáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This thesis focuses on water jet technology. In the theoretical part of the thesis, the principle and classification of this technology, the quality of the cut surfaces after water jet cutting, the types of bevels, and the equipment needed for this technology are described and analyzed. It also describes the use of an abrasive water jet in machining and summarizes the advantages and disadvantages of this technology. Additionally, the thesis presents the machinery of the company with which the author of the diploma thesis worked, as well as its production range. The practical part of the work is devoted to the experiment, which consists in selecting a component for the production of samples using two abrasive nozzles, with subsequent assessment of the quality of the machined surfaces in relation to the size of the diameter of the abrasive nozzles as well as in relation to the materials and their thickness. Two materials of two different thicknesses were used for the samples. The quality of the machined surfaces was measured using two roughness meters. The average arithmetic deviation of the profile Ra and the largest height of the profile Rz were measured. At the end of the thesis, the deflection of the beam is measured using a microscope, and the consumption and the price of the abrasive for individual sample components were also calculated.

Manufacturing of metal yoke of electrical socket by compound tool
Svozilová, Lucie ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated design of technology production of the metal yoke of electrical socket made of steel DX51D + Z200 by compound progressive tool. Stock material for series of 200 000 pieces is a strip of coil. Manufacturing is realised in five steps consist of cutting, bending and flanging. For flanging was constructed a special mechanism for whose is necessary to use hydraulic counterholder, which is sold as a special peripheral equipment of manufacturing machine. The machine choice was adapted to this criterium. The servopress DSF-N1-800A was chosen as a manufacturing machine, which is made by AIDA company. The press can produce force of 800 kN and make work of 4000 J. Selling price of a one yoke is 24,5 Kč when the profit is one hundred percent. The break-even point comes with 58 140 made piece.

Forming technologies of non-ferrous materials
Zuhla, Michal ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
This work is focused on the surface forming, in particular, non-ferrous metals. There are described methods of cutting, drawing and bending. For each of these methods are listed and summarized the issues. There are also given individual production technologies cutting, drawing and bending, along with examples of products and their use. The work is complemented with an overview of the most important non-ferrous metals. For these metals are described their properties, suitability for molding and their alloys.

Production of joint folded out the rule
Šoukal, Hynek ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
Project developed within the bachelor study presents a proposal production technology of joint folded out the rule from construction steel 12 060. Thick is 0,5 mm and the production ran is specify at 30 000 units a year. In accordance with literature studies and by calculations have been designed a combined roll forming tool, which consists of a rack with two pillars. This tool will be fix in on eccentric press LEN 10C by SMERAL, Trnava, with nominal press force 100 kN. Trimming punches, holding punch and bending puch are made of tool steel, grade 19 436.3. Lower functional part of the tool ass well.

Manufacturing of a Cable Holder
Šimka, Radek ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The bachelor’s thesis proposes a design for the production technology of the cabling holder, situated in the outdoor part of the air conditioner. This product is made of steel sheet DC01 with a thickness of 1 mm. The production of this holder is set to be 200 000 pieces per year. A progressive die tool was selected as the most suitable type of production technology, based on a literature study of various production technologies. This enables to combine cutting and bending of steel sheets with the use of one tool device. Manufacture will be performed using a mechanical eccentric press LEN 63 C. All the necessary requirements of this device are satisfactory for the production.

Production of cover drain
Hollein, Radek ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
Diploma thesis deals with the design of producing the cover drain. The cover serves to catch impurities while draining liquids. The part is made of 1.4301 stainless steel, using 1-mm thick sheet metal. The size of the annual production series is 30,000 units. As an optimal method of production, progressive cutting and shallow drawing were selected in a combined and a one-purpose tool. Technological and design calculations were performed according to which tools were designed. The LENP 100 press was selected considering the total required pressing force. The cost of one piece production was calculated at 18.91 CZK and the production becomes profitable with annual production higher than 19,478 units per year.
