Abstract

Inventia se refera la o stanta combinata pentru executarea pieselor inelare profilate, cum ar fi de exemplu, inelele Pall folosite la coloanele de extractie din industria chimica. Stanta, conform inventiei, este alcatuita dintr-un subansamblu superior dotat cu poansoane de taiere si perforare si un subansamblu inferior avand în componenta o placa activa de taiere. Pentru a realiza toate operatiile necesare pe aceeasi unitate de lucru sunt folosite niste poansoane de crestere dispuse pe doua randuri paralele astfel încat sa cresteze simultan cele doua margini ale unei benzi fixata între niste rigle de ghidare care apasa asupra benzii crestate, între niste cepuri de roluire montate în niste butuci actionati de doua stifturi prin intermediul unor furci sustinute de doua arcuri de compresiune si doua semimatrite care realizeata formarea completa a inelului prin închiderea capetelor benzuu sub actiunea unui sistem de role sustinute de nuste coloane si de niste arcuri.The invention relates to a combined stator for the execution of profiled ring parts, such as, for example, the Pall rings used in the extraction columns of the chemical industry. According to the invention, the stator comprises a superior subassembly with punching and punching pins and a lower subassembly having an active cutting plate. In order to carry out all the necessary operations on the same work unit, some pins of growth are arranged on two parallel rows so as to simultaneously increase the two edges of a strip fixed between guide guides pressing on the notched strip between some rolls mounted in two hubs driven by two forks supported by two compression springs and two semi-matrices that made complete ring formation by closing the benzine ends under the action of a roller system supported by columns and some springs.
