Casted Formula Student Upright
Doležal, Tomáš ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
Bachelor thesis deals with a design of casted upright for Formula Student vehicle Dragon X. Casting method used for the purpose of this thesis was selected by review of relevant scientific literature. The upright was then structurally designed and strength calculations were made. Main criterion of the design is minimum compliance with meeting the required weight. Final design is compared with the design of the previous generation of vehicle.

Manipulator for folding molds
Borýsek, Lukáš ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The diploma thesis deals with the design of manipulator construction for folding two-part molds. In the thesis, an analysis of the current state of knowledge in the field of handling equipment and industrial robots is generally performed. Subsequently, the work introduces the current issue of handling equipment that is used in foundry. Furthermore, the work deals with the analysis of the manipulator construction, choosing the appropriate solution for the construction of its own handling equipment. Design solution is supported by computational message, 3D model and drawing documentation of selected nodes. The conclusion is devoted to the evaluation of work and practical recommendations.

Dropping Production in the Company
Eibelová, Lucie ; Šiška, Přemysl (referee) ; Juřica, Pavel (advisor)
The bachelor thesis focuses on the reduction of administrative and error rate in manual removal of the production in the foundry. The analysis maps the current state of the processes in the operation and shows how it works. This thesis presents a proposal to solve the problem by introducing the MES system, which is installed in the foundry.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.

Casting technology in automotive industry
Andrle, Jiří ; Valášek, Petr (advisor) ; Hrabě, Petr (referee)
The goal of this work is to analyse materials and technologies used in casting process in the automotive industry. The work is divided into three main parts. The first part describes materials udes for castings. There are described ferrous materials - cast iron and tempered iron, and lightweight alloys that are increasingly used - aluminium, magnesium and titanium alloys. The next section describes casting technologies used in the manufacturing process of the car, including the innovative methods that are being implemented to automobile manufacturing process. The last part is dedicated to the development and innovation of casting technology. In particular, the simulation of casting process using computer programs that are capable of realistically simulating the course of casting. These methods are described in terms of their practical use in the manufacture of high quality castings further used in the automotive industry.

Pendulum jaw crusher 1 600 x 1 250
Ješuta, Jiří ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis deals with the design of the construction of a pendulum of a single toggle jaw crusher. The first part of this thesis treats the mechanical raw minerals disintegration. In the second part the characteristics of a single toggle jaw crusher and double toggle jaw crusher are compared. The third part addresses the calculation and the construction of the main components of the jaw crusher. Next part of the thesis consists of the calculation of the crushing force, the pendulum design, and the method of manufacturing a pendulum. The strength analysis of the designed pendulum using the finite element method (FEM) in program NX-Ideas is made in the last part of this thesis.

Application of Modern Technologies for Production of Front Part Fastening System Mountaineering Crampons
Samohýl, Lukáš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim this bachelor thesis is a production of prototype front part fastening system mountaineering crampons. In this work will be carried out the design and construction of a new prototype parts using the parametric application SolidWorks. For prototype production front part crampons will be used additive method Fused Deposition Modeling - uPrint 3D printer. Part of the work will be production of silicone moulds front part crampons using vacuum casting system. Silicone mould will be used for casting of a certain number parts from commercially available materials. The work will be finished with technical and economic evaluation of production front part crampons with recommendations and the best economic analysis of alternatives.
