Abstract:
The aim of the thesis is the design of the production process and tools for production of two grooves in coats of concrete clamp. Shell anchors are made of longitudinally welded stainless steel tubes 17 240. The size of the production of all types of shell of concrete clamps is 18 000 PCs per year. The number and the dimensions of grooves in the coats of anchors were determined on the basis of a practical verification. To the present day the grooves are made by cutting on a band saw, which is little productive and on finishing operations demanding way. The grooves in the coats of anchors will be newly manufactured by technology of shearing, which was a literary study. On the basis of the calculations was selected for the production a hydraulic press of CUPS 25 D. The grooves will be produced on the newly designed shearing tool. Work is carried out by technical-economic evaluation, which compares the current technology of production with the newly proposed technology. Part of the thesis is drawing documentation of coats of concrete clamps of all dimensions and drawing documentation of shearing tool.

This master’s thesis has been elaborated as a part of master’s studies of engineering technology M2I-K, major in M-STM – Engineering technology and industrial management and deals with the problem of a transition to a self-production of previously purchased distance washers. Distance washers were purchased in six different types of similar shape, each type in four different thicknesses. One of these types was chosen as a representative for this master’s thesis. We shall explore the possibilities of self-production with the emphasis on economical validation of the transition. The distance washer is a flat part, the intermediate being sheet metal. Technologies considered for manufacturing the washers correspond to the technical facilities and equipment available at the production hall of the company this project is planned for. The company possesses technology for CO2 laser cutting, cutting by CNC punching machine and cutting in the punching tool. To provide a complex overview we shall also enquire into cooperated technologies such as water jet and plasma cutting, oxy-acetyleny cutting and CNC working. All options are evaluated with regard to the production expenses and lead to a most economically plausible method of manufacturing or, if need be, give reasons for going back to purchasing the part from the current supplier.

Full text
Abstract:
Localization of deformation occurs in Earth's crust as a consequence of applied stress and is widespread phenomenon that can be found in crustal rocks. Such localization of deformation can be mostly seen in a form of shear zones. Small shear zones referred as shear bands or S-C structures are often used as kinematic indicators. However, the evolution and kinematic continuity of such structures is not well identified, which makes it problematic when interpreting regional geodynamic evolution. Two possible cases were distinguished and described in this thesis: a) kinematically discontinuous S-C structures formed during two deformation events and b) kinematically continuous S-C structures formed during single deformation event. Kinematically unrelated S-C structures were studied in westernmost part of Tauern Window in Eastern Alps and in Gemer-Vepor Contact Zone in Central West Carpathians where previous geodynamic interpretations might have misinterpreted localization structures. Kinematically continuous shear bands were studied in South Armorican Shear Zone where the S-C fabrics were originally defined and described (Berthé et al., 1979). Two fabrics that crosscut each other at small angles forming S-C geometries were documented during field work and studied from macroscale down to microscale or...

Full text
Abstract:
Upper part of the orogenic crust (superstructure) significantly differs from the lower part of the crust (infrastructure) by structural and metamorphic record. This fundamental observation is explained by interruption of the mutual evolution due to mechanical decoupling of the hot and ductile infrastructure from the cold and brittle superstructure at certain stages of the orogenic evolution. The superstructure-infrastructure transition zone is a rheologically predisposed domain of sharp deformation and metamorphic gradients with polyphase structural record. Understanding of the deformation partitioning in such a rheologically complex setting is a key aspect in linking of the individual deformation stages between upper and lower crust. The transition zone between unmetamorphosed early-Variscan superstructure (Teplá-Barrandian Domain) and late Variscan high- grade infrastructure (Saxothuringian Domain) crops out at the western margin of the Teplá- Barrandian Domain in the Bohemian Massif. This area is a continuous mid- to lower-crustal section with early-Variscan structural and metamorphic record, which is superposed onto pre-Variscan episode. This thesis aims to decipher individual deformation events, to evaluate their manifes- tations at different crustal levels and to bring new and unifying...

Abstract:
ENGLISH ABSTRACT The Late Devonian to Early Carboniferous kinematic evolution of the Teplá-Barrandian/Moldanubian boundary The Staré Sedlo complex (SSC) is a relic of meta-igneous arc-related pluton in the southern part of the Sedlčany-Krásná Hora roof pendant, intruded by granitoids of the Central Bohemian Plutonic Complex along the boundary of Teplá-Barrandian (TBU) and Moldanubian units (MU), Bohemian Massif. The SSC mainly comprises deformed orthogneisses of calc-alkaline granodiorite to tonalite protoliths of Late Devonian age (380−365 Ma; Košler et al., 1993) that were commonly mingled with minor basic magmas. Locally preserved subhorizontal intrusive contacts of the orthogneisses against their meta-sedimentary host rock indicate that these magmas intruded as a sill complex. The SSC preserves a rather unusual flat-lying subsolidus foliation (dip <40ř) associated with subhorizontal ~NE-SW-trending mineral lineation. Mesoscopic structures, anisotropy of magnetic susceptibility (AMS), and deformational microstructures indicate prolate shape of the strain ellipsoid with dominant coaxial pure shear regime. The solid state microstructures record cooling of the orthogneiss protolith down to the ambient greenschist facies conditions followed by its static recrystallization due to the intrusion of the younger...
