This thesis deals with optimization of a press line part for the manufacture of reflectors present at the Automotive Lighting Company, Jihlava. The first part focuses on describing the current workplace layout of the press line. The workplaces are located inconveniently and thus require a larger number of operators and a considerable amount of manual work. The second part of the thesis proposes layout solutions for the injection presses and for other machine parts. At the same time, a smoother transition design is proposed for the press line and for the manufacturing section that follows. Based on an evaluation of selected criteria, the optimum version is chosen, thereby adding to the efficiency of the molding process by reducing the number of operators required, by lowering the proportion of manual work relative to other activities, and by limiting the risk of poor quality. The conclusion of the thesis sums up the necessary investment costs and offers an economic assessment of introducing the selected press line arrangement to operation.

Moreover this thesis includes the design of an electrical control and the design of hydraulic block and manifold.

This thesis deals with the proposal of an oil filter body manufacture. The oil filter body is a rotational part made of DC02 deep drawing steel. With respect to the material, geometry and the size of the production, a deep drawing technology which does not consider wall thinning, was chosen. It was decided about necessity of five drawing operations. Suitable presses for a notching line and the very drawing were selected. Next part of the thesis is given to the design of the rolling tool construction. A drawing die for the first operation is described in details, including the controls and drawings. The economic part compares variants with the requirements of monthly production of 50 000, 180 000 and 350 000 pieces respectively. Due to the economic study, the production of 180 000 pieces per month was chosen.

The thesis deals with the design and arrangement of a new paint line at company Automotive Ligting s.r.o in Jihlava. It deals with design of several possible options of arrangement of machines that are required for the processing of polycarbonate granules and their conversion into acrylic glass using two-component injection molding. The glass is then coated with the coating line which is part of the arrangement included in this project. Design of the individual sites and their organization is based on both the company's requirements and the principles of technological design. The best of the three options is analyzed in detail and evaluated from the economic point of view.

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.

Study developed during the Master's degree studies of Mechanical Engineering deals with the use of recycled plastic in the injection molding and its influence on the mechanical properties of the mold. Examined product is used in the automotive industry as a connector body. The housing is manufactured from a plastic material, polyamide. The annual production volume of 3 000 000 pieces. According to tests specified in standard USCAR2 regrind influence on mechanical properties and dimensions was evaluated. After the technical evaluation of the project, research was also judged from economic point of view. In this task, savings with the different content of the recycled material during production was calculated. The final chapters justify change of properties and they are proposing the use of recycled materials in practice.

This master’s thesis deals with a proposal of production technology of a fireplace insert. Based on various solutions of production and documented calculations, charring has been elected as the most optimal technology. According to the requirements of thermal resistance and weldability the component will be made of boiler metal plate 11 416. Based on checking and technological calculations process of charring on press BAYKAL APHS 3110x180 has been proposed with the nominal power of 180 tons. The verification of bends was realized using computer simulations. Bending tools are made of steel 12 050. A technical-economic evaluation is also part of this master’s thesis.

The thesis deals with the design of the upper part of the gas tank. Taking into account the shape and dimensions, the solution was chosen the most advantageous drawing technology without a thinning of 1 mm thick DC04 steel. The solution took account of the requirements of the contracting authority and selected the production for one operation. However, the simulation proved inappropriateness of the solution, so the procedure was modified to two operation proces. At the first stroke, a larger part of the body will be created, and in the other, a calibration of the cut-out dimensions will occur. For the first operation, the design of the tool kit, including drawing documentation for the CTH 250 press, was elaborated.

This diploma thesis deals with the design and realization of a detachable joint for transferring a large torque from a drive to a driven member in a vertical forging press. The first part analyzes the disadvantages of production, assembly and disassembly of the original wedge joint of eccentric shaft and gear. The design of a new detachable joint is intended to remove the disadvantages of the original joint. Verification calculations are part of the proposal. The next part deals with the production of joint elements and the modification of the connected components for the designed joint.

The aim of this thesis was to conduct an experiment in which the efficiency and performance of a screw press were monitored during various modes of operation. The theoretical part of the thesis was focused on a more detailed specification of selected types of nuts. This part also contains a description of individual types of nut trees and their fruits in terms of their practical usage and substances contained. Another objective was to examine the significance and application of nut oils in individual domains of human activity, such as industry, gastronomy, pharmacy, cosmetics, and others. Last but not least, the technical capacities for ensuring mechanical pressing with screw press were introduced and described. The practical part was focused on the process of mechanical pressing using a Farmet UNO screw press. In the first part of the experiment, differences in performance and extraction yield were observed depending on the type of nut being pressed, but also on substances contained in extracted oils. The second part of the experiment focused on pressing of a single type of material, namely peanuts. The performance and extraction yield of the press was observed during three chosen modes of operation. Finally, data regarding performance and extraction yield of Farmet UNO press was processed and evaluated. This was done from the perspective of differences between pressed materials and differences between individual modes of operation. Results of laboratory analyses of substances contained in extracted oils were also processed and compared. This diploma thesis produced rather demonstrable results that can be taken into consideration during practical application.
