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.

Manufacturing of a Car Door Lock Segment
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.
