Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in the figure, this preferred embodiment comprises at least vertical deflector roll 2, flat deflector roll 3.Wherein, deflector roll 2 is found for being supported on gantry channel-steel wing plate inwall, for gantry channel-steel provides side guide and guard.As Fig. 2, vertical deflector roll 2 is preferably multiple, and the lead direction along gantry channel-steel is arranged as two parallel row, so that gantry channel-steel thereon passes through smoothly.As Fig. 3, each vertical deflector roll 2 is all vertical settings, and also namely its rotation is vertical.When specifically arranging vertical deflector roll 2, each vertical deflector roll 2 includes a vertical roll shaft 6, and vertical roll shaft 6 installs vertical deflector roll 2 by bearing.As Fig. 2, flat deflector roll 3 for being supported on below gantry channel-steel web, for gantry channel-steel provides horizontal guide and guard.It is horizontally disposed with, and also namely rotation is vertical with the lead direction of gantry channel-steel, and specifically, flat deflector roll 3 is flatly arranged on foreplate 1 afterbody by plain-barreled roll axle 7.
In order to draw gantry channel-steel more stably, and reduce the quantity of vertical deflector roll 2, flat deflector roll 3, this preferred embodiment also comprises foreplate 1.As shown in Figure 1 and Figure 2, foreplate 1 cross section is the grooved that Open Side Down, generally speaking, foreplate is the channel-section steel structure square hollow section steel shape structure in other words that Open Side Down substantially, and extend along the lead direction of gantry channel-steel, its afterbody upper surface is provided with flat deflector roll 3, and vertical deflector roll 2 is installed in side.Preferably, foreplate 1 head has gradient, and external diameter diminishes, and is convenient to guide rolled piece; Afterbody also makes external diameter diminish with slope, is convenient to guide rolled piece.
In the preferred embodiment, vertical deflector roll 2 is six, and wherein two one group of shapes are in a row, totally three rows.Flat deflector roll 3 is one, is installed on the afterbody upper surface of foreplate 1.In other embodiments, if without gantry channel-steel passage, be all made up of the extraction channel of gantry channel-steel vertical deflector roll 2, flat deflector roll 3, then the quantity of vertical deflector roll 2, flat deflector roll 3 can increase greatly.
More specifically, as Fig. 3, as shown in Figure 5, vertical roll shaft 6 one end and the foreplate 1 of vertical deflector roll 2 are fixed, the other end is fixed by the bearing 5 below locking nut and foreplate 1, vertical deflector roll 2 is connected by two deep groove ball bearings and vertical roll shaft 6, and two deep groove ball bearings are located at the two ends of vertical deflector roll 2 inner chamber.Preferably, the outer peripheral face of vertical deflector roll 2 protrudes from the side maximum height of foreplate 1 is 5-8mm.Flat deflector roll 3 major part embeds foreplate 1 afterbody, and fraction protrudes to foreplate 1 web upper surface and realizes horizontal guide and guard to stretch in gantry channel-steel passage.Preferably, the outer peripheral face of flat deflector roll 3 protrudes from foreplate 1 web upper surface maximum height is 3-6mm.As Fig. 4, flat deflector roll 3 is connected by two deep groove ball bearings and plain-barreled roll axle 7, and two deep groove ball bearings are located at the two ends of flat deflector roll 3 inner chamber, and the plain-barreled roll axle 7 of flat deflector roll 3 is fixed by locking nut and foreplate 1.
In order to make the structure of gantry channel-steel passage more stable and be guided out hot rolling gantry channel-steel more smoothly, this preferred embodiment also comprises bearing 5.Bearing 5 is fixed on the below of foreplate 1.As Fig. 3, as shown in Figure 4, bearing 5 is also substantially in tabular, and its length direction is consistent with the length direction of foreplate 1.Preferably, vertical roll shaft 6, through mounting nuts after bearing 5, makes bearing 5 fix with foreplate 1.
In order to prevent vertical deflector roll 2, flat deflector roll 3 overheated and change the interior tissue form of hot rolling gantry channel-steel, as in Figure 3-5, this preferred embodiment also comprises cooling tube 4, it is for carrying cooling medium to cool the peaceful deflector roll 3 of vertical deflector roll 2, the openend of cooling tube 4 is positioned at foreplate afterbody lower end, lead in cavity that foreplate 1 and bearing 5 formed, carry cooling medium to described vertical deflector roll 2, flat deflector roll 3.
During use, be installed on rolling mill frame window by this preferred embodiment by bearing 5, foreplate 1 head contacts with roll pass, and after rolled piece is guided out pass, the wing plate of rolled piece will contact with vertical deflector roll 2.After rolled piece moves to foreplate 1 afterbody, its web contacts with flat deflector roll 3, fundamentally make the extraction of forklift door frame channel-section steel operate whereby and become rolling friction from sliding friction, thus exactly rolled piece is guided out roll pass, and rolled piece is passed through smoothly, there is not rolled piece surface tear, improve hot rolling gantry channel-steel product surface quality.
To sum up, the invention provides a kind of hot rolling forklift door frame channel-section steel outlet rolling guide device, sliding friction between rolled piece and guide and guard is become rolling friction by it, can reduce the cut owing to being formed because of sliding friction between rolled piece and guide and guard, improves hot rolling gantry channel-steel product surface quality.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
