This master’s thesis is focused on the design of the technology to produce a part of the TV bracket. The part is made of steel sheet with a thickness of 2.5 mm. The structural steel S235JR was chosen as the most suitable material with following powder coating. From the possible variants, the production by progressive forming tool was chosen with respect to production requirements and a series size of 30 000 pieces by year. The part will be made in seven steps in designed tool and the total required force is 1013 kN. The production will take place on a mechanical press PCK12 from Bliss-Bret with a maximum force of 1250 kN. The final price of the part is 39.4 Kč.

This master´s thesis focuses on the concept of manufacturing of carbon brush holder, made of steel S235JRG (ČSN 11 343), with thickness of 1,5 mm. In order to reduce costs, it was decided to manufacture the holder with progresive stamping tool, which combines cutting, bending and edging operations in order to achieve specific part shape. Based on relevant calculations the mechanical press LEN 63 C was chosen. The production series was set at 50 000 pieces.

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.

The project drawn up within engineering studies, field N2307-00, presents a design for processing a single part – the part is made of sheet steel number S235JRG1 by shearing and bending. On the basis of literary study was design compound tool which is working in three steps. The tool is fixed in eccentric press LEN 40 C (producer TOMA Industries, s.r.o.) with nominal force 400 kN. Blanking punch and blanking die are made from tool steel 19 436 according the drawing documentation.

The project elaborated in frame of engineering studies branch 2303T002. The project is submitting design of technology production of the part from the deep drawing sheet iron 11 320.30. Pursuant to of the literary pursuit a problem of the shearing, bending and calculation was designed manufacturing in transfer combined die, which is set on the eccentric press LEXN 100 C (producer TOMA INDUSTRIES s.r.o. Trnava), with nominal force 1000 kN. Functional parts of tool are produced of tool steel 19 436.3.

The in the framework of Master’s Studies developed project presents a technology- proposal for the production of a pressing tool for the manufacturing of parts from the sheet steel DD13. On the basis of a literary survey of problems of the component manufacturing through shearing, bending and the studies of heat treatment and applications of covering coat and calculation, manufacturing in the phase-shearing tool was proposed. The press GERB EDELHOFF 80 t was selected as the working device.

KVAPIL Jan: Bending and cutting press machine for representativ part The Master´s thesis, which is developer in an undergraduate degrese in M-VSR, provides a brief overview and description of the cutting and bending technology. The thesis is carried out the calculation, which is essential for the design cutting and bending tools. Models and design are created in the software SolidWorks 2012. The Master´s thesis includes a general procedure after the award until after copy the parts on it.

This master’s thesis focuses on the concept of large-lot manufacturing of sheet metal component made from DC01 steel. Based on forethought, the method of compound tool combining shearing and bending was chosen. The theoretical part analyses used technologies in detail. In the next part specific course of manufacture was created and supplied with technological calculations. Based on all needed facts the tool was designed and after that forming machine, LDC 160 crank press, was chosen. At the end the usability of designed concept was confirmed with economical calculations.

This project is conceived within the master's degree in engineering technology and industry management (M2I-K Engineering) technology by design of the brake disc cover in compound tool, with year production 500 000 pcs. The material is deep-drawn sheet metal 11 305.21, 1 mm thickness. It is based on the literature studies about forming and calculation was suggested several variants of the present components. The proposed tool is clamped in the crank press LDC 400 firm Šmeral with a nominal force of 4000 kN. The functional parts are made from steel 19 573. The proposed technology of the deep drawing was verified by using simulation program AutoForm.

In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. The strain paths can be visualized in a Forming Limit Diagram(FLD); with a Forming Limit Curve (FLC) corresponding to the strained material.In the diagram, the determination whether an element is critical due to fracture ornecking is determined. Utilizing the FLD, the formability of a material is defined;the elements and their paths are however linear. Manufacture a sheet metal usinga multi-stage forming process will contribute to Non-Linear Strain Paths (NLSP).Thus, the FLD is no longer valid. Providing a tool from the company RISE IVF AB to be used for pre-strainingoperations, the objective of this thesis work is to enhance and investigate the possibility of generating the three main strain paths - uniaxial tension, plane strain,equibiaxial tension - of the dual-phased steel DP800. This study is in collaborationwith Volvo Cars Body Components (VCBC) in Olofström, where the pre-strainingwill be used in a future study of the SMF non-linear behaviour. Utilizing the finiteelement software AutoForm - specialized on SMF operations - this numerical basedstudy can be conducted. The ability of generating the three main strain paths will be achieved by modifying the blank geometries and provided tooling. By changing the dimensions ofthe punch and draw beads, critical regions and forced concentrated straining weresupposed to be achieved. These changes are implemented with the intention to fulfillthe criterion of the straining in terms of magnitude and gradient. The result from the simulations shows that the modifications have different effecton both the straining level and gradient. The modifications of both the draw beadand the punch were not of any significant use, while the blank dimension was mostvital when generating sufficient strain paths. Hence, the tooling modifications withinthis thesis work did not enhance the prediction of the three strain paths.
