Abstract

Inventia se refera la un procedeu si la un dispozitiv de confectionarea profilurilor curbe, în special a profilurilor de bare de protectie din profile cu pereti subtiri, inclusiv cu sectiune asimetrica si înaltime mare a profilului, variabila de-a lungul piesei, prevazute cu elemente de forma secundare si strapungeri. în scopul simplificarii procesului tehnologic, cresterii productivitatii si îmbunatatirii calitatii pieselor prelucrate, procesul consta în trecerea unui semifabircat profilat într-un flux continuu automatizat format dintr-un sector de profilare continuat cu un sector de încovoiere urmat de un sector de calibrare, bratele profilate ale piesei profilate fiind îndreptate, înainte de efectuarea curbarii, în sus perpendicular pe inima profilului în sectorul de profilare, în sectorul de calibrare putîndu-se confectiona dupa efectuarea curbarii oricare sectiune transversala a profilului piesei.The invention relates to a process and to a device for the production of curved profiles, in particular of the profile bars of thin-walled profiles, including the asymmetrical section and the high profile height, the variable along the part, provided with elements secondary form and straps. in order to simplify the technological process, increase the productivity and improve the quality of the machined parts, the process consists in passing a profiled semifabricate into an automated continuous stream consisting of a continuous profiling sector with a bending sector followed by a calibration sector, the profile piece being directed, upstream of the curvature, up perpendicularly to the profile heart in the profiling section, in the calibration sector being able to produce any cross section of the profile of the workpiece after the curvature.
