Abstract

Inventia se refera la un procedeu si la un dispozitiv de ralizare a tuburilor telescopice spirale, utilizate în constructia de masini ca aparatori pentru suruburile conducatoare. Procedeul consta din înfasurarea dupa o elice, a unei benzi de otel cu pasul corespunzator aparatorii telescopice, pe un dorn format din mai multe suprafete cilindrice dispuse în trepte, dornul fiind prevazut la un capat cu un canal, în care se introduce banda de înfasurat. Forma definitiva a tuburilor este stabilizata printr-un tratament termic corespunzator. solutia are aplicatii în industria constructiilor de masini unelte.The invention relates to a process and to a device for splicing telescopic spiral tubes, used in machine construction as guards for guide screws. The process consists in placing a propeller, a steel strip with the corresponding telescopic strips on a mandrel formed by a plurality of stepped cylindrical surfaces, the mandrel being provided at one end with a channel in which the strip is inserted. The final form of the tubes is stabilized by appropriate heat treatment. the solution has applications in the machine tool construction industry.
