Abstract

Inventia se refera la un dispozitiv de avans pentru masini-unelte cu prescrierea fortei, utilizat în special la masinile de prelucrat cu ultrasunete, necesar realizarii avansului cu mentinerea unei forte de apasare constante sau variabile în functie de conditiile de lucru, între scula si piesa, pe durata prelucrarii Inventia rezolva problema cresterii productivitatii masinilor de prelucrat cu ultrasunete prin pastrarea fortei de apasare dintre scula si semifabricat la o valoare optima cu realizarea concomitenta a avansului necesar prelucrarii si prin posibilitatea introducerii comenzilor adaptive prin închiderea unei bucle de reactie pentru reglarea fortei de apasare dupa o marime care caracterizeaza procesul, prin intermediul unui variator de c.a. si a unui motor asincron cu alunecare marita.The invention relates to a device for advancing force-prescribing machines, especially used for ultrasonic processing machines, necessary for the advancement by maintaining a constant or variable force, depending on the working conditions, between the tool and the piece, during processing The invention solves the problem of increasing the productivity of ultrasonic processing machines by keeping the pressing force between the tool and the blank at an optimal value with the simultaneous realization of the advance required for the processing and by the possibility of introducing the adaptive controls by closing a reaction loop for adjusting the pressing force after a size that characterizes the process, through a ca variator and an asynchronous engine with increased sliding.
