The thesis deals with the design of technology for production of weapon conclusion by die forging. The weapon conclusion will be made of C45 steel in series of 500 000 pieces per year. Before forging, the base semi-finished product will be treated using cross-wedge rolling technology. Thanks to the chosen production process, the forging will be made as four pieces. A simulation of the forging process was made for the created design. Results of a simulation showed that metal did not fill entire hollow. Based on these results was made changes in design and the simulation was performed again. According to the results of the second simulation, the hollow has already been filled with metal. For the forging was chosen the machine LZK 2500P from Šmeral a.s with a nominal force 25MN. In the conclusion there was a technical-economic evaluation of costs for the material required for production of entire series. |
