Abstract

Ovaj pronalazak se odnosi na uredjaj za valjanje radnih komada, kao što su ploče ili šipke, posebno limova, a koji se sastoji od: bar jednog valjačkog stana (1); bar dva pogonjena radna valjka (2, 3), koji su obrtno uležišteni u pomenutom valjačkom stanu (1), koji su u medjusobnoj sprezi pri valjanju pomenutog radnog komada u željeni oblik i/ili dimenzije, postavljenih upravno na pravac valjanja (4); bar jedan od pomenuta dva radna valjka (2,3) je pomerljiv u odnosu na pomenuti valjački stan (91), upravno na pravac valjanja (94), i u vezi je sa jedinicom za (13,14), pritisak koja je sposobna da stvara pritisak valjanja (N) na radnom valjku; pri čemu je bar jedan od radnih valjaka (3, 4) bez ikakvog potpornog valjka i uležišten je obrtno u potporni nosač (11,12), koji je smešten nasuprot oblasti valjanja, podupirući bar jedan deo spoljne površine (9, 10) pomenutog radnog valjka (2, 3) u vidu udubljenja; naprave za stvaranje stalnog filma maziva izmedju spoljnih površina (9, 10) pomenutog radnog valjka (2, 3) i potpornog nosača (11, 12), pri čemu potporni nosač (11, 12) poseduje bar jednu zapreminu u obliku žljeba (29, 30, 32 do 35), uradjenu u delu pomenutog potpornog nosača (11, 12), u kome je uležišten pomenuti radni valjak (2, 3) i pri čemu je pomenuta naprava spojena sa izvorom fluida; i pri čemu je pomenuti radni valjak (2,3) spojen preko pomenutog potpornog nosača (11, 12) za pomenutu jedinicu (13,14) za pritisak radi prenošenja pritiska valjanja; i pri čemu je jedinica (13, 14) za pritisak izvedena kao naprava za prenošenje pritiska valjanja ravnomerno duž cele dužine pomenutog potpornog nosača (11, 12), preporučljivo u vidu jednog ili više hidrauličkih radnih cilindara (H). Glavna prednost ovog pronalaska je što daje znatno jednostavnije i ekonomičnije rešenje, uklanjanjem potpornih valjaka pomoću novog sistema uležištenja, isključujući tako habanje i gubitke energije, neizbežne kod tradicionalnih uredjaja.The present invention relates to a device for rolling work pieces, such as plates or bars, in particular sheets, comprising: at least one rolling mill (1); at least two driven work rollers (2, 3), which are pivotally mounted in said roller flat (1), which are interconnected when rolling said workpiece into the desired shape and / or dimensions, arranged perpendicularly to the rolling direction (4); at least one of said two rollers (2,3) is movable relative to said roller flat (91), perpendicular to the rolling direction (94), and is related to a unit for (13,14), a pressure capable of generating rolling pressure (N) on the work roller; wherein at least one of the working rollers (3, 4) is without any support roller and is pivoted in a support carrier (11,12), which is located opposite the rolling area, supporting at least one part of the outer surface (9, 10) of said working roller (2, 3) in the form of recesses; means for creating a permanent lubricant film between the outer surfaces (9, 10) of said work roller (2, 3) and the support carrier (11, 12), wherein the support carrier (11, 12) has at least one groove-shaped volume (29, 30, 32 to 35), made in the portion of said support carrier (11, 12), in which the said working roller (2, 3) is mounted and wherein said device is connected to the fluid source; and wherein said working roller (2,3) is connected via said support bracket (11, 12) to said pressure unit (13,14) to transmit the rolling pressure; and wherein the pressure unit (13, 14) is designed as a device for transferring the rolling pressure evenly along the entire length of said support bracket (11, 12), preferably in the form of one or more hydraulic service cylinders (H). The main advantage of the present invention is that it provides a much simpler and more economical solution, by removing the support rollers by means of a new bearing system, thus eliminating wear and loss of energy, unavoidable in traditional devices.
