Production trough wiring
Broža, Pavel ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis introduce a proposal of technology production shape components by shearing and bending. The specified component will be made from galvanized sheet DX51D + Z 275 with a thickness of 2 mm. On the basis of literary studies and calculations was determined shearing by simple stamping and bending on press brake. For the production were selected eccentric press EZN 6 with a nominal force of 320 000 N and press brake MENGELE 50/2050 with a bending force 500 000 N. Technological proposal is supported by the attached drawings.

Production of cover plate
Rubáš, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the proposal design of the technology of the production of the cover plate of the lock, which together with other parts forms part of the fifth door of the passenger car. The cover is made of 2 mm metal sheet and includes a number of bends, embosses, cuts and trimmed holes. Based on production requirements and a series size of 1,200,000 pieces over 3 years, the production using a progressive composite tool was chosen. The part will be made in eleven steps composing of cutting, stamping, bending and edging. Micro-alloyed structural steel S355MC was chosen as the most suitable material. The part will be produced on the press KSTU 5000-30-7G RKM from the company ANDRITZ Metals and the price of the product is 14,33 CZK.

Manufacturing of wall clamp
Isakidis, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The design which was work out in college plan M2I-K is setting up a production technology for an wall clamp from a steel plate 11 321.1. Based on the literature search it was chosen optimal technology of cutting and forming. Structural and technological calculations were implemented for these methods and the composite machine tool was projected. The eccentric bending press CDCH 3000P was chosen because of its working power. Working parts of the tool are made from steel 19 436.3. Price of the component is 36 Czech crowns which is result

Uses of a cutting die in the manufacturing process
Důrek, Milan ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The bachelor’s thesis elaborated as part of a bachelor's degree of the branch mechanical engineering submitted a proposal of use cutting technology in the manufacturing process. The specified component is a tine and it is made of abrasion resistant and high-strength steel. The tine is produced in a series of 200,000 units / year. The first part of the thesis is pointed to technology of material cutting. For this technology a literature summary was made including a description of the requirements for the calculation of shearing machines and tools. In the second part, cutting tool was chosen based on technological calculations. For this instrument has been chosen crank press LKJA 1000 with a nominal force of 10 000 kN. The study evaluate the economic comparison of laser and cutting tool.

Forging of a hinge eyebolt
Puklický, Vladimír ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
Bachelor thesis developed in the bachelor degree addresses the production process eyebolt combination of the two technologies volume thermofotming. Forging the forging and die forging slug for making the final shape of the part. Eyebolt will be produced in a series of 5,000 units / year of structural steel ČSN 11 375.1 with a carbon content of 0.2 % C. The material is supplied in the form of round bars with a diameter of 135 mm and a length of 6000 mm . From this it will be cut smaller pieces using a 172 mm long industrial scissors ScKU 800 Based on the literature study and fitting the calculations was chosen for forging hammer KHZ 4 A from Šmeral Brno as and drop forging hammer with the designation L 9 mg in 2040 by a French company Bché . Semi-finished product is heated in a gas chamber furnace RKG 08.9.03-12 with an output of 600 kW. Forging the trimming on the trim press LKOA 200th Dies are made of tool steel DIN 19 663.

Manufacture of car lock components
Andris, Tomáš ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on the proposal of manufacturing technology of the opening lever for a car latch. The lever is made of S355MC sheet metal with thickness 2 mm, production series is set for 400 000 pieces per year, which includes 200 000 pieces of right and 200 000 pieces of left version. After considering several production methods, combined progressive die was chosen. The part is made in ten steps, which include shearing and bending. Necessary technological, design and safety calculations were also made. For production was chosen eccentric press S160 made by ŠMERAL company. Surface protection of the part will be provided by galvanizing. At the end of the thesis a technical and economical evaluation is provided. The final price of one piece of lever is calculated to 13,3 Kč, economical turning point when production become profitable was calculated to 156 339 pieces.

Suitable lubricants for deep drawing of steel
Hřebíček, Pavel ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The aim of this work is experimental evaluation of suitability of lubricants for drawing of stainless steel 1.4301 at elevated temperature, which corresponds to temperature in real process. The lubricant testing method is based on friction modeling between the pull edge and the retainer, which corresponds to the real process. Therefore, the design of the test fixture also conformed to this model. The result of the work is a comparison of the suitability of every single lubricants with the reference lubricant used in ACO Industries. The best results were obtained with AT Kalorex 650 S lubricant, which contains environmentally harmful additives.

Suitable lubricants for deep drawing of stainless steel
Doležal, Jan ; Chudík, Ivan (referee) ; Lidmila, Zdeněk (advisor)
This thesis solves problems of design and construction of testing equipment for testing lubricants for deep drawing and experimental evaluation of suitability of different types of lubricants for specified tests conditions. Most of all it is about finding environmentally friendly lubricant which would provide similar results as lubricants containing chlorine compounds when drawing a stainless austenitic Cr-Ni steel 1.4301. As for lubricants provided for testing by leading home and abroad manufacturers, the ATLAS 3374-140 from Quaker Chemical and the WISURA ZW 3356 from FUCHS, were evaluated as the most suitable environmentally friendly lubricants.

Manufacturing of the anchoring element of a solar collector
Svobodová, Helena ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
In this master's thesis the proposal of the production technology of component – solar collector anchor element from steel 1.0038 (11 375) quality, 5 mm thickness is solved. For the manufacturing of the assigned part the shearing and bending technology and a progressive forming tool including a suitable forming machine of 8,000 kN rated power is selected. The proposed method of production is laid down by a technical-economic evaluation with respect to the production series of 150,000 units per year. The solar collector anchor element serves to hold the frame for the solar vacuum tube collector. In the scope of this master's thesis, an assessment of the current production method, including the selection of a suitable semi-finished product for production, was also carried out and their optimization was proposed.
