The Diploma thesis describes the implementation of innovative production of protective liner to the manufacturing company. The liner is manufactured in sizes of nominal diameter DN 200 - DN 500. The material is low-alloy steel EN 10216-2 10CrMo9-10. For the production innovation, the technology of pipe end flaring by a movable mandrel was chosen. Verification of the functionality of this technology was performed using analytical calculations and numerical simulation of FEM. The results of numerical methods were compared with the results of a practical experiment. The experiment was performed on 5 test specimens with a diameter of 273 mm. The machine device was a hydraulic press with a nominal force of 2000 kN and equipped with pressure and position sensors. The experimentally obtained values of force and the tool path dependence were similar with the values of FEM simulation. The difference in the value of the force in the maximum tool path was 290 kN. The flared diameter was formed to a value of 319 mm. This value corresponds to 16.5% of increased nominal diameter, which is sufficient from design point of view. Non-destructive tests ruled out the presence of crack defects on the flared diameter. According the new set up working procedure was produced the first real part. Significant financial savings of CZK 3.5 - 5.3 million / year were quantified in the technical and economic evaluation. Return on necessary investments is between the 9th - 14th manufactured pieces (approx. 15% of the annual production volume). In conclusion, innovation has promising results and will be issued by the company into the production process.

The thesis proposes a concept of manufacturing the folding meter lock. The part is made from DC01+LC steel of 0,3 mm thickness. The series size is 100 000 pcs/year. A forming in a progressive combination tool combining shearing, bending and stamping was chosen for the production, based on the analysis of possible solutions. The tool, designed on the basis of literary research of used technologies, produces the part in eleven steps exerting maximal force of 38,5 kN. The production will take place on an eccentric press LEN 40 C. The market price of 3,38 Kč for one piece was established by the technical and economic evaluation.

The project drawn up within the framework of engineering studies in discipline Manufacturing technology (2303T002) presents a proposal for processing a single part – the part is made of sheet steel number S420MC – by blanking, bending and stamping. On the basis of a literary exploration of given problems several variants of processing a part was propounded in order to be made in just one tool. The transfer combined die is fixed in crank press WAINGARTEN ARP 80 with 800 kN nominal force. All functional parts are made of heat treated tool steel number 19 573.3 according to drawing documentation. Lower functional parts of tool (blanking die, stamping die and bending tool) are made as divided.

The aim of this diploma thesis is to propose a production technology of a given part based on technological and economic factors. At first it is found, if the part is producible by fineblanking. The theoretical part of the diploma thesis is concerned with the description of the conventional sheet metal cutting theory, fineblanking theory and bending theory. In the practical part of the diploma thesis, four variants of cut-in plan are dealt with including the selection of the optimal one based on technological and economic calculations. It is the production of a PULL REAR iron made of the steel sheet 11 320.21, thickness of 3 mm and a production run of 75 000 pieces per year.

The Master´s thesis is elaborated within the framework of graduate´s study by institute of The Engineering technology and composed the technology of fineblanking process. The required component is made by stainless steel 17 240. The technological and constructional proportions were designed and calculated for required technology. The tool cuts out for one stroke one component, and is designed for mechanical three-active press MFA 1600 made by Feintool. The material’s strip of the scroll is situated in single sided rewinders QOPJ 160/650, and managed through leveling machines QRVP 160 into tools. The total force of press is 1600 kN. The main functional parts tools are made by steel 19 436, 19 437.

This thesis submits a proposal production technology of single parts from sheet steel No. 11 305, thickness of 2 mm, made from a semi-finished product with a diameter of 246 mm, production run of 50 000 pieces per year. To manufacture the component a technology of hydromechanical drawing is proposed. On the basis of a literary study and calculations a drawing tool was designed, fixed in hydraulic press LPS 4000. To prepare a semi-finished product, flange trimming, and hole punching, a sheet metal cutting is used.

The aim of this thesis is constructional concept of diaphragm press for thermoplastic forming. The press consists of two chambers. First chamber is designed for forming of semi-finished product to forming temperature and second chamber is designed for heating the semi-finished product. Theoretical part of this thesis is focused on technologies in use and shaping of plastic description. Practical part of this thesis deals with detailed description of press concept including consistence calculations and drive units calculations. The whole concept, including its individual parts, is designed using the Autodesk Inventor software. At the end of this thesis, there is the economic and safety analysis.

The aim of this diploma thesis is processing the new technology of production single parts from metal plate „ Vanečka", which produced is yearly set 50000 pieces. Component of made in steel S235JRG1 (ČSN 41 1373) thickness 3 and 5 mm. Based on literary search rolling cutting and bending are designed two variants of production. Both variants use for cut - out cloak and face rolling cutting close - set on press LEN 63C. Different operation is bending. First variant includes bending in the bending tool, the other on press brake. Both variants is processed economics revaluation and consequently intended transition points.

The diploma work contains a solution of the production technology of a sleeve made of metal sheet 11 373.1, the thickness of which is 1,5mm, in the required amount of 36,000pcs a year. Out of all possible options, the production of cutting and bending in a sequential combination tool was chosen. Based on the literary study and performed calculations the tool is designed and chosen eccentric press LEN 40 C. The price of 2,40 CZK for a piece is derived from the economic evaluation. The work contains drawing documentation of chosen parts of the tool and its assembly.

Based on study of documents supplied by PWO Unitools a.s. and on advices of design office staff, tool for forming flanges was designed. This tool was then manufactured and it has been used for carrying test of creating flanges of various diameters from high-strength steels. During these tests, the following parameters were optimized – force of upper and lower blank holder and the height of the main guides. Threads were created into these drown flanges. These threaded joins were later tested for maximum torque and maximum compressive strength.
