TY - JOUR AU - Korotun, K. AB - PERFORATING DIE PUNCHES SLOTS IN ENCAPSULATED BUBBLE CAPS (UDC 621.733.4) Engineer K, M. Korotun Translated from Khimicheskoe i Neftyanoe Mashinostroenie, No. 5, p. 43, May, 1965 Slotting of bubble caps is the most difficult and labor-consuming operation in the fabrication of encapsulated caps used in rectification towers. 38 slots sized 4 by 30 mm are driven in a singte !00 mm diameter cap. A single- position die will make one single slot in one stroke of the press. A multiposition perforating die designed on the basis of an innovation by N. I. Vivdichenko and since adapted for production is capable of driving slots in five caps simultaneously. The die set (see drawing) consists of the baseplate 10, spider body 5, and punch holder 13 with five punches 12. Five heads 9 are mounted on the die body to accommodate the capstocks, place clamp 11, and turntable. As the sliding block of the press advances upward, the connecting rod 1 and lever 2 cause the ratchet 3 to rotate one tooth ahead, thereby causing the spindle 6 and the driving bevel pinion 4 to rotate. The rotation is transmitted via the intermediate bevel and cylindrical pinions 8 to the spindles TI - Perforating die punches slots in encapsulated bubble caps JO - Chemical and Petroleum Engineering DO - 10.1007/BF01144970 DA - 2005-01-28 UR - https://www.deepdyve.com/lp/springer-journals/perforating-die-punches-slots-in-encapsulated-bubble-caps-QRtSlraxrj SP - 413 EP - 414 VL - 1 IS - 5 DP - DeepDyve ER -
