The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.

The paper evaluates technological, economic and construction aspects of the component production and the design of the tool serving for large-scale production of the S355MC steel rack component. Use of a progressive tool combining cutting and bending operations in four steps has been decided as the most appropriate according to literature study. Based on the need of production of two plane-symmetrical pieces at a time, the tool will produce both pieces simultaneously, which is economically advantageous. The tool is designed for use on the Arisa 630t mechanical press. Material will be winded off the roll, flattened and pushed into the tool by a precision feeder. The total cost of production of the component was set at 18.80 CZK.

This master’s thesis presents a proposal for the technology of manufacturing sheet metal part, which is a part of a bicycle wall bracket. The component is made of steel sheet ČSN 11 325 with subsequent surface treatment by galvanizing. Due to the chosen method of manufacturing with a progressive stamping die, the research part is focused on the technology of shearing and bending. Technological calculations were performed for the most suitable production variant, on the basis of which a mechanical press ANDRITZ Metals with the designation KSTU 2000-20-4G-PSE was chosen. Furthermore, the design of the tool itself is presented, which is substantiated by drawing documentation. At the end of the work, a technical and economic evaluation of the produced series of 300 000 workpieces per year is calculated.

The thesis deals with the design of a single-purpose process tool for the production of sheet metal parts. It contains an analysis of the technologies used by the tool, the calculation of important quantities such as shear clearance, bending radius, suspension and more. The topic also deals with the description of important parts of the tool and their functions.

The project, which have been created within the framework study of engineering branch N2326, submit project technology process of pressing - part from micro-alloyed steel with higher yield point H 240 LA and proposal of tool design for its pressing. Technology process was designed in ten operations, base on literary studying of cold forming technology. Design of progressive die respects type of press machine, which is specified for production this part. Press KRUPP 400t disposes pressing force 4 000kN. Materials, used for design of tool, are in use by tool shops. Punches and punching dies are produced from steels 19 573, heat-treated according drawing documentation. Drawing punches and dies are produced from steel 19 552, hardened on 56+2HRc and coated by TiCN method.

The project presents design of technology production of the hinge made of metal sheet plate 11 321. The variant proposed solutions have been designed manufacturing cutting and bending technology in transfer combined die. These themes were elaborated in literatures studies. As a working machine was selected eccentric press LEN 40 C of Slovak producer TOMA INDUSTRIES s.r.o., Trnava, with a nominal force 400 kN. Functional parts are made of tool steel 19 436. In economic results was defined cost of one piece including manufacturers profit and the break-even point, which is coming after production of 151 966 pieces.

Diploma thesis deals with the design of producing the cover drain. The cover serves to catch impurities while draining liquids. The part is made of 1.4301 stainless steel, using 1-mm thick sheet metal. The size of the annual production series is 30,000 units. As an optimal method of production, progressive cutting and shallow drawing were selected in a combined and a one-purpose tool. Technological and design calculations were performed according to which tools were designed. The LENP 100 press was selected considering the total required pressing force. The cost of one piece production was calculated at 18.91 CZK and the production becomes profitable with annual production higher than 19,478 units per year.

The thesis handle design of part of anemostat in size of series 15000 pcs/year. Due to conus shape and dimensions of part was chosen out of quantity of manufacturing processes a technology of deep drawing without a thinnig of 1mm thick DC04 steel. The resulting solution is progressive tool which concatenate four operations of deep drawing process. The drawing tool make use of standardised components. The design contain progressive tool including drawing documentation. Hydraulic press CTH 400 with nominal force 4000 kN is used for mentioned procedure.

The thesis is focused on the proposal design of the technology of the production of the cover plate of the lock, which together with other parts forms part of the fifth door of the passenger car. The cover is made of 2 mm metal sheet and includes a number of bends, embosses, cuts and trimmed holes. Based on production requirements and a series size of 1,200,000 pieces over 3 years, the production using a progressive composite tool was chosen. The part will be made in eleven steps composing of cutting, stamping, bending and edging. Micro-alloyed structural steel S355MC was chosen as the most suitable material. The part will be produced on the press KSTU 5000-30-7G RKM from the company ANDRITZ Metals and the price of the product is 14,33 CZK.
