Manufacturing of metal yoke of electrical socket by compound tool
Svozilová, Lucie ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated design of technology production of the metal yoke of electrical socket made of steel DX51D + Z200 by compound progressive tool. Stock material for series of 200 000 pieces is a strip of coil. Manufacturing is realised in five steps consist of cutting, bending and flanging. For flanging was constructed a special mechanism for whose is necessary to use hydraulic counterholder, which is sold as a special peripheral equipment of manufacturing machine. The machine choice was adapted to this criterium. The servopress DSF-N1-800A was chosen as a manufacturing machine, which is made by AIDA company. The press can produce force of 800 kN and make work of 4000 J. Selling price of a one yoke is 24,5 Kč when the profit is one hundred percent. The break-even point comes with 58 140 made piece.
The Antenna Bracket Manufacturing by a Compound Tool
Lipka, Ondřej ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
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.
Corner fitting manufacturing by compound tool
Loukota, David ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
Project have for purpose propose acceptable technology for manufacturing corner fitting by compound tool. Corner fitting is made from steel sheet 11 321.1 thickness 1,5 mm in production set 600 000 pieces in a year. Was select variant with manufacturing compound tool, which make to part on four steps on automatized manufacturing line. This line includes press about power press 1000 kN, feeding and levelling serving and containing rewinder. In economic results are calculated costs production of a piece, final costs and break-even point which is coming after production 216 049 pieces.
Form shim manufacturing by compound tool
Bartoš, Martin ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
Purpose of this diploma thesis is a design of a compound tool for manufacturing the form shim. The form shim is made by shearing and bending technology from steel sheet 11 343.1. Thickness is 2 mm. On the basis of a literary study and design calculations was designed the compound tool, which will manufacture this component by 4 actions on the automated line containing rewinder, feeding levelling machine and eccentric press with designed compound tool. Economic calculations show that the designed manufacturing is profitable.
Manufacturing of the TV Wall Bracket
Kráčmar, Lukáš ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This master’s thesis conducted within the master's degree focuses on the design of production for component, which is a wall-mount the TV. The blank is sheet steel DC03 and the annual production is 300,000 pieces. After exploring possible options of manufacturing was chosen compound tool. In the theoretical part were explored technology used cutting and bending. Further, the manufacturing process and tool design were made. The suitability of the solution was verified by economic evaluation.
Stirrup manufacturing by compound tool
Brodský, Zdeněk ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The master´s thesis deals with drawing compound tool for production of stirrup. Stirrup is made from steel 17 240 and his thickness is 1,5 mm. The number of production is 400 000 pieces. After completion of constructional calculations was determined eccentric press LEN 40 C and was designed tool. The work is completed by drawing documentation of the compound tool. In the work is performed economic evaluation too. Present technology (blanking, bending) is compare here with new technology- compound tool. Compound tool is profitable, because time and money are saving.
The manufacture of protecting sheet part with use compound tool
Pustějovský, Petr ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
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.
Manufacturing of a Cable Bottom Part of a Switchboard
Radnický, František ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This master´s thesis is focused on design of suitable technology of cable bottom part of a switchboard, made from aluminum EN AW-1050A. As the semi-finished product is chosen the coil of sheet metal with a thickness of 2 mm. The production series of this component is 300 000 pieces per year. To select the most suitable technology for the production of solved component the evaluation of different available technologies was carried out, of which as the most appropriate method, the compound tool combining shearing and bending is selected. Literary search was created to the mentioned technologies. Furthermore, the technological and constructional solution is elaborated, which also includes the design of the combined process tool. As a forming machine was selected eccentric press Mecânica Exacta DM 250, where the compound tool is clamped. In the last phase, a technical and economic evaluation is performed to verify the suitability of the proposed solution.
Manufacturing of part of door lock by compound tool
Nečas, Petr ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
Academic thesis, drawn up within the framework of engineering studies, presents a proposal optimal production of garage door lock striker. The part is manufactured from steel sheet S275JR of 1.5 mm thickness. By the analysis of its possible methods of production, with regard to the required annual series of 500,000 pieces, was chosen technology of manufacturing the part in the compound tool by blanking and bending processes. For these technologies was designed solution of the compound tool and automatic production line with the eccentric crank press SMERAL S160, where is the compound tool fixed. The measure of financial performance of manufacturing the part is economical assessing. In the current state is investment return in the production of 179,186 pieces of the parts.
