Abstract

The invention relates to the manufacture of ring articles from sheet material, for example abrasive, used in grinding machines. The purpose of the invention is to increase productivity. The device comprises a punch 4, in which an outer knife 5, an inner knife 6 are installed. A clamp 7 and an ejector 8. The matrix is made up of a composite part 9 and a rotary part 10 with an annular gap 11 between them located opposite the outer knife 5. The rotary part 10. is made with an annular groove 12 opposite the inner blade 6, fixed to the lever 14 and provided with a rotatable spring-loaded support 17. By turning on the power cylinder 3, the punch 4 moves downward, the clamp 7 and the ejector 8 clamp the abrasive tape 25. I cut the knives 5 and 6 t abrasive belt 25. When you turn on the power cylinder 21 swivel bearing 17 with a rotary part Yusan lower position. The ejector 8 pushes down the finished product 24, which falls into the pallet 23. 2 C, f., 3 sludge. w Ё
