Description

Katowniki jak i teowniki otrzymuje sie przewaznie przez walcowanie w specjalnie ^kalibrowanych walcach, które trzeba sto¬ sunkowo czesto zmieniac ze wzgledu na roz¬ maitosc wymiarów profilów. Mozna tez otrzymac katowniki przez wyginanie plas¬ kowników na specjalnych maszynach lub tez przez rozcinianic wzdluz srodników ko¬ rytek, przez rozcinanie zas wzdluz srodni¬ ków dzwigarów mozna otrzymac teowniki.Równoczesnie otrzymuje sie od razu dwa katowniki lub teowniki .zamiast jednego wy¬ walcov/anego.Rozcinanie mozna stosowac do ksztalto¬ wników twoirzyw zelaznych, stalowych, wszelkich innych metali i mas sztucznych.Na zalaczonym rysunku fig. la i b wska¬ zuja, jak sa rozciete dzwigar i korytko, fig. 2 wskazuje urzadzenie wedlug wyna¬ lazku, fig. 3a, 3b i 4 wskazuja otrzymane w tym urzadzeniu ksztaltowniki.Z dzwigara przez rozciecie otrzymac moz¬ na teowniki normalne lub tez dlugoszyjko- we, z korytka zas — katowniki równora- mioranc, jak i nierównoramienne (fig. la ib).Rozcinanie mozna wykonac albo palni¬ kiem tlenowym recznym lub samosterowym, pila na zimno, pila na goraco w czasie wal¬ cowania, nozycami krazkowymi w czasie walcowania na goraco. Nozyce moga byc ustawione oddzielnie lub wbudowane bez¬ posrednio za walcami formujacymi (fig. 2), lub utworzone w kalibrze walca przez spe-cjalne jego uksztaltowanie. Mozna tez w kalibrze walca wykonac wstepne rozcina¬ nie, dalsze zas rozcinanie uskuteczniac tak, jak wyzej podano.Dla katowników równoramiennych i nie- równoramiennych o równej grubosci ramion rozcinanie musi byc polaczone z równoczes¬ nym przelamywaniem w walcach formuja¬ cych w czasie walcowania (fig. 4).Unosizac lub opuszczajac górny walec otrzymuje sie równe grubosci scianki s oraz wstepne rozcinanie. Dalsze rozcinanie usku¬ tecznia sie osobno, zapomoca jednego z wy¬ zej podanych narzedzi. PLAngles and tees are usually obtained by rolling in specially calibrated rolls, which have to be changed relatively often due to the variety of dimensions of the profiles. It is also possible to obtain angles by bending flat bars on special machines or by cutting holes along the webs, and by cutting along the centers of the girders, one can obtain T-sections. At the same time, two angles or tees are obtained at once instead of one cylinder The slitting can be used for ferrous, steel, all other metals and artificial masses. In the accompanying drawing, Figs. 1a and b show how the girder and trough are cut, Fig. 2 shows the device according to the invention, 3a, 3b and 4 show the shapes obtained in this device. From the spar, it is possible to obtain normal or long-necked tees from the spar, while from the channels - equal angles and unequal angles (Figs. La and b). make either with a hand-held or self-steering oxygen burner, cold saw, hot saw during rolling, with rotary shears during hot rolling. The shears can be positioned separately or built in directly behind the forming rolls (Fig. 2), or formed in the caliber of the roll by a special shape. It is also possible to make a preliminary cut in the caliber of a roller, and further cut as described above. For isosceles and non-isosceles angles with equal thickness of the arms, the cutting must be combined with simultaneous breaking in the forming rolls during rolling ( 4). Raising or lowering the upper roll, the same wall thickness s is obtained and a pre-slitting. Further cutting is performed separately by using one of the above-mentioned tools. PL
