Racionalizace výroby matrice střižníku

Abstract

his thesis was focused on the production rationalization of Die Punch, which is used during the pressing. This matrix is placed in a punch tool which contains several of these matrices. Originaly was this matrix manufactured on an older type of machine, because of the complexity of the process. The main emphasis, due to the frequent replacement of these matrices, was placed on increasing the accuracy and quality with regard to maintaining or redcing the cost of production. Original old machines achieved sufficient accuracy, but we are able to achieve a longer life service of a tool at a higher quality and accuracy. The work was focused on the rationalization of production punch matrix, which is used during pressing. This matrix is placed in a punch tool that contains several such matrices. Originally the matrix, because of the complexity electro manufactured on older machines. Due to the frequent replacement of these matrices with emphasis on increasing the accuracy and quality with regard to maintaining or reducing production costs. Original obsolete machines achieve sufficient accuracy, but at a higher quality and accuracy achieved an increase in tool life. The theoretical section will focus on the essence and principle of non-conventional machining, mostly elektroinvasive machining. The practical part is focused on the choice of machine, types of cutting wires, the choice of optimal conditions for unconventional machining and the resulting surface finish. The influence of elections machines, cutting conditions, the technology of progress will be considered to the final production of the matrix. In the final part of this thesis, the technical – economic evaluation and assessment of election machines of Die punch will be considered.
