Abstract

Inventia se refera la un procedeu si o matrita de planat piese executate din table care s-au deformat în urma stantarii sau care au fost executate din benzi înfasurate în colaci. Procedeul consta în deformarea pieselor între cele doua placi care au pe fetele de lucru ondulasii conjugate. La aceasta operatie curba de îndoire a piesei se transforma într-o serie de curbe mult mai mici atît ca pas si ca sageata. Dupa operatia de deformare piesa, cu profil ondulatoriu se planeaza tot între doua placi de formare, proeminentele placilor de formare actionînd de proeminentele piesei. Matrita este alcatuita dintr-o placa de baza în care sunt fixate coloane de ghidare pe care gliseaza o placa. Pe placa este prinsa o placa de formare superioara ce are pe fata de lucru ondulatii conjugate cu ondulatiile unei placi de formare inferioare prinsa pe placa de baza. Valoarea sagetii ondulatiilor pe placile de baza este maxima la mijlocul acestora, în directia longitudinala si descreste treptat spre capete, în asa fel încît în poyitia închisa a matritei piesa sa nu prezinte nici o deformare la capete ti sa aibe o deformare maxima la mijloc.The invention relates to a process and a molding of parts made of sheets which have been deformed by stinging or which have been made of strips embedded in coils. The process consists in deforming the pieces between the two plates having the conjugated corrugated working faces. In this operation the bending curve of the piece turns into a series of curves much smaller both as a step and as the arrow. After the deformation operation, the track with the corrugated profile is also planted between two molding plates, the protrusions of the forming plates acting on the protrusions of the workpiece. The mold is made up of a base plate in which there are fixed guide columns that slide a plate. On the plate there is a superior forming plate having on the face of work the curls conjugated to the corrugations of a lower forming plate attached to the base plate. The magnitude of the corrugation arrow on the base plates is maximum in the middle in the longitudinal direction and gradually decreases towards the ends so that in the closed form of the mold the piece does not show any deformation at the ends and has a maximum deformation in the middle.
