Abstract:
The thesis deals with the production concept of the bracket for fixing the drying frame. The component is made of 11 343 steel. The semi-finished product is galvanized sheet with 2 mm thickness. With regard to the required quality of the component and the yearly production quantity (40,000 pieces), a new production technology was chosen based on a literary study by means of conventional shearing in a tool, followed by bending on a press brake. For the selected technologies, technological calculations and a cutting tool were designed, which are dealt with in the drawing documentation. The work also includes technical-economic evalua-tion of the proposed production method.

Abstract:
The thesis presents a design of a progressive cutting tool for the production of shaped blanks from sheet metal Usibor 1500 (22MnB5) with a thickness of 1.5 mm. The tool is designed by using CATIA V5 software in cooperation with Žďas, a.s. company. Based on the literature review of the cutting process, cutters were designed, shear clearance and order of operations in the tool were determined. The proposed cutting tool consists of both manufactured and standardized parts. Tool parts fall out of the chute onto the conveyor belt. The tool is designed to operate on an AIDA 1000 excentric press with a nominal force of 10,000 kN. Cutters that are not standardized are made of tool steel and heat treated according to drawing documentation.

Abstract:
This thesis explains how to determine and eliminate the causes of quality problems in the production of connectors and small electronic components for the automotive industry. The process of making these components is carried out by use of both high speed and low speed metal stamping presses. There are descriptions of the different designs of editing punches, stamping dies, trimming and molding tools and how unplanned issues can occur during the production process. It addresses all the customer requirements for quality end products, listing the type of material, finishes and technology used for the production of individual components as well as their functionality, durability, and economic impacts. All examples of changes in the design or technology of metal stamping presses are based on many years of practical experience and most of them can be successfully applied in other similar type of instrument production.

Abstract:
The aim of the thesis is to design a manufacturing technology of a part of the universal opener with an innovated design. The component is made of stainless steel 17 240 (X5CrNi18-10). The blank is 2 mm thick sheet metal. Within the literary study the comparison of the possible technologies of manufacturing has been carried out. With respect to the batch size (200 000 pieces) and to the required quality of the component the fineblanking technology has been selected. For the manufacturing of the component a triple action hydraulic press HFA 3200plus has been chosen. This press will be coupled in production line with a feeding line FBA 8/300. The main point of the thesis is to design a cutting tool and to create a drawing documentation. Another part of the project is the technical and economical evaluation of the designed manufacturing process.

Abstract:
The master’s thesis elaborates an optimum proposal of the production technology of a cutting – a part made of steel plate 11 320.3. The theoretical part represents the problematic issue of cutting technology and on the basis of this part was designed a production of components in processual tool. The processual tool is composed of normalized components and is resolved by using a easel, which is attached into the eccentric press LEXN 100 C (producer Toma Industries) with the nominal drawing force of 1000 kN. The press was chosen on the basis of technological calculations. The work contains necessary calculations, economical evaluation and design documentation of the cutting tool for the components production. The last part contains the technical and economic evaluation of the recently designed technology.
