Manufacturing of a Segment of the Seat Positioning System
Horák, Jan ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis is focused on the design of technology for the production of a seat positioning system made of sheet steel ČSN 11 373 with a thickness of 2 mm. Due to the adjustment of the production quantity of 200 000 pieces per year, the required dimensional accuracy and surface quality of the cutting surface is used by the technology of production of fine blanking with a pressure edge. Part of the work is the implementation of technological and construction calculations, including the design of the cutting tool with the necessary drawing documentation. An alternating arrangement of cut-outs for a coiled sheet metal blank (Ds = 1 200 mm, ds = 500 mm) is chosen as most suitable in the work, which means the use of 36 coils for a given annual production. In the final part of the work, a three-acting hydraulic press Feintool HFA 8800plus is chosen for the production of the component, which is incorporated into the automated production line FBA 6/300, including all necessary equipment for handling, unwinding and straightening the cut sheet metal strip.

Production of check valve's part
Růžička, Pavel ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis deals with the production innovation of the return valve disc component used in pumping technology. It is a component made of sheet metal with 3 mm thickness, the quality of material is according to ČSN 11 320. Existing production using cutting technology in a process tool will be replaced by a modern, more accurate and especially more economical method by precise cutting with a pressure edge. Based on the literature study of precision cutting, assessment of production technology and processing of design solutions, the cutting tool was designed to be able to significantly speed up and reduce the cost of production of the component. It will be placed in a three-acting press from Feintool, namely XTF Speed with a nominal force of 1500 kN. In the final technical and economic evaluation, it was proved that the newly designed technology is able to bring a component of the same nature to the market, but at a significantly lower price.

Manufacturing of a safety buckle by fineblanking technology
Ryza, Dominik ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The goal of this diploma thesis is to design a manufacturing technology for the safety buckle. The component is made of steel 11 320. The thickness of the used metal sheet is 3 mm. For the production of the part has been chosen the technology of fine blanking process with pressure edge. This type of manufacturing guarantees the demanded high quality of this special O.E.M. It also makes possible to produce volume up to 700 000 pieces per year. The cutting tool is designed to produce three blanks per one production cycle of the machine. The manufacturing will be done on the triple-action press HFA 3200plus with a feeding line FBA 8/300.

The manufacturing of car latch component by fineblanking technology
Augste, Jakub ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of engineering studies branch Manufacturing Technology (N2307-00) is submitting design of technology production of the latch claw. The latch claw is a component of a car side-door latch assembly and can be used for different car models. The part is made of sheetmetal 4 mm thick. The material for the part is 15CrMo5, alloy steel for case-hardening purposes. Pursuant of the literary pursuit was designed several options of the part manufacture. With regard to required dimensional accuracy, cut-edge quality and expected production run (800 000 pcs. per year) was proposed manufacturing the part by fineblanking technology. Fineblanking is a cost-effective manufacturing method for accurate sheetmetal parts. For manufacturing parts was chosen Feintool hydraulic fineblanking press HFA 3200plus with total force 3200 kN. The press is coupled to a coil reel a strip straighter. Both units of Feintool feeding line FBA 8/300 are very compact, reducing space requirement. For the fineblanking tool design is used a moving-punch system because these tool systems are compact and economical to make and use. The tool make use of standardized cast iron fineblanking die set made by Fibro company. At the conclusion was compared the cost-effectiveness between two production methods – fineblanking with that of laser beam cutting.

Cutting components with higher accuracy to size
Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.

Vrtiška, Roman ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The bachelor thesis is focused on production of car door lock segment, which is made of steel 15CrMo5 with a thickness of 4 mm. Based on the established production quantity of 280 000 pieces per year, the prescribed dimensional accuracy and surface quality of the cutting surface, the technology of fine blanking with vee-ring is chosen. In the practical part of the work, technological controls of the manufactured part are carried out. A coil of the sheet metal as a semi-finished product and cutting plan with the highest percentage utilization were chosen. For established quantity production, 61 pieces of coil weighing 500 kilograms are needed. Based on the technological, control and construction calculations, the tool is constructed, including drawing documentation. Due to the calculated overall force Fc = 1 085,85 kN and the top view area of the tool the triple-action mechanical press XFT 1500speed is chosen. The press is part of the line with the FBA 6/300 coil processing line.
