Increasing the life of blanking punch by coating
Šplíchal, Jan ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
This Bachelor thesis presents possible methods for increasing the lifespan of cutting tools made of steel 19 436 designed for cutting stator and rotor plates made of silicon steel. These sheets are characterized by high hardness, which adversely affects the edges of the scissors. Experimental hardness measurement on delivered samples has verified the actual heat treatment on the surface and inside the scraper. The measured value 62 HRC corresponds to the input requirements. Based on the literature study, a combination of chemical – heat treatment and coating was chosen as the most appropriate method. In order to preserve the microstructure of the punch produced after the heat treatment, it was necessary to apply the coating by physical vapor deposition, which is characterized by low deposition temperatures. The FeinAl coating will be applied by cathodic arc deposition and is primarily designed to protect tools and cutting tools.

The manufacturing of sheet metal part by blanking technology
Žák, Ondřej ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
ŽÁK Ondřej: The manufacture of sheet metal part by blanking technology The project elaborated in frame of engineering studies branch 2307. The project elaborated in frame of bachelor studies in engineering technology field set up proposal technology of production of feed lame – a section from steel metal plate 11 320. Processual shearing was suggested on the basis of belles-lettres problem of blanking and calculation. Shearing use standardized component and is solved by form of usual rack close set on press LEN 25-C, with nominal ductile by force 250 kN. Blanking puch and blanking are made from 19 class alloyed instrumental steels, heat treated according to graphical documentation.

Production single parts from sheet metal
Hrnčál, Zdeněk ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
Project elaborate in terms of engineering studies branch 2303T002 submits proposal technology of production single parts from deep drawing press steel metal plate 11 305.21. On the basis literary study problems blanking, deep drawing and calculations was designed drawing in instrument with holder, to extrusion components serves lower ejector. Combination tool is set on hydraulic press CTH 250 with nominal tensile by force 250 kN. Drawable tools (drawing punch, drawing die) and shear pin tools (blanking punch, blanking die) are made from instrumental steels 19 436.3, heat treated condition to drawing documentation.

Sheet metal part manufacturing by drawing
Moravec, Jiří ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The project developed in the frame of the bachelor study branch B2307-00 presents a proposal of acreation technology of a flange, which is to be a model of the roof lift. The part is made of steel 11 320. Due to the anticipated serial production of 10 000 pieces per year, a number of production options is considered. On the basis of literary studies of the issue of drawing, it is suggested a drawing by a metal tool with blankholder. Due to calculations of tensile strength and work, press LEN 40 C is suggested. Drawing tool is designed to require the most of standard components and is solved through the form of a normal rack fastened to the eccentric press LTN 40 C. Drawing punch and drawing die are made of tool steels 19 436.3 and heat-processed according to the drawing documentation.
