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.

Aim of the project is to design new flange manufacturing technology. The flange is manufactured from stainless sheet 17 040 with 5 mm thickness and annual production batch of 800 000 pieces. Fineblanking process has been proposed as a new production technology. Technological and construction dimensions have been designed for the proposed technology. The fineblanking process is done by automated machine which consist of unwinding and straightening device, mechanical punch press and winding device. The manufactured part is punch pressed by tool which is located in the punch press in one lift. An economic evaluation compares current manufacturing technology with the proposed technology which is more economically convenient.

The aim of the thesis is to design a manufacturing technology of a part of the universal opener with an innovated design. The component is made of stainless steel 17 240 (X5CrNi18-10). The blank is 2 mm thick sheet metal. Within the literary study the comparison of the possible technologies of manufacturing has been carried out. With respect to the batch size (200 000 pieces) and to the required quality of the component the fineblanking technology has been selected. For the manufacturing of the component a triple action hydraulic press HFA 3200plus has been chosen. This press will be coupled in production line with a feeding line FBA 8/300. The main point of the thesis is to design a cutting tool and to create a drawing documentation. Another part of the project is the technical and economical evaluation of the designed manufacturing process.

Aim of this Thesis is to assess the existing manufacturing method and to propose and make out an optimum manufacturing method for the part „seat belt buckle“. Components made of the steel plate 14 220.3. With respect to requested accuracy, quality and expected production run of 1 000 000 pcs per year, the Thesis includes the proposal of manufacture of the part by a method of accurate cutting with push-on edge. Is designed the cutting tool and selected the suitable machine type for this technology Feintool HFA 3200 Plus. The work contains necessary calculations, economical evaluation and design documentation of the processual tools for the components production. The last part contains the technical and economic evaluation, from which results that, technically and economically, the new production technology is preferable to the existing technology.
