Abstract

Procedimiento y dispositivo para fabricar sin desprendimiento de viruta, un cilindro hueco, especialmente una carcasa polar para máquinas eléctricas, con po lo menos una sección final corta con menor diámetro exterior, rebajada preferentemente en ángulo recto, partiendo de un trozo de tubo cilíndrico, caracterizado el procedimiento porque se sujeta el trozo de tubo cilíndrico sobre un mandril de sujeción giratorio, concéntricamente a éste, y la sección final corta rebajada con menor diámetro exterior, se produce por laminación en frío con un cilindro laminar perfilado correspondientemente a la sección final, que se acciona en rotación y se desplaza hacia el mandril de sujeción por un eje conducido paralelamente al mandril de sujeción
