As shown in fig. 6, roll bending device 7 includes to export the dynamic roller set 71 set gradually along roll bending device 7, determine roller set 72 With transfer roller group 7875 and the first rotational structure, the second rotational structure；Roller set 72 is determined for positioning to continuous beam 8；Institute Roller set 71 is stated to export set on roll bending device 7 and determine roller set 72 relatively；Transfer roller group 7875 is for transmitting beam column；And it is dynamic Roller set 71 is realized up and down and is swung by the first rotational structure and the second rotational structure respectively, to realize the roller of beam column It is curved.

Determine roller set 72 and transfer roller group 7875 and same horizontal line is mounted on by roller frame and dynamic roller set 71 respectively On, so that beam column is determined the transmission of 72 direction of roller set as transfer roller group 7875 is past under the drive of engine, moves roller set 71 and connect It connects in the first rotational structure, is rotatably connected in the second rotational structure at left and right sides of the first rotational structure, the second rotational structure Up/down end is connect with 7 mouth rotation of roll bending device, when the rotation of the first rotational structure opposed roller bending apparatus 7, and the second rotation knot Structure remains unchanged, then beam column one end is fixed by determining roller set 72, and the other end is servo-actuated roller set 71 and swings up and down, and with transfer roller Wheel group 7875 is along transmission direction successively to one side's roll bending of swing；When the rotation of the second rotational structure, and the first rotational structure is kept Constant, then beam column is servo-actuated the left and right swing simultaneously of roller set 71, and stretches out roll bending after being successively in certain radian roll bending to swing side Device 7 exports；When the first rotational structure and the second rotational structure rotate simultaneously, beam column may be implemented towards upper left side, lower-left The roll bending of side, upper right side, lower right, and be rocked to certain angle in the first rotational structure and/or the second rotational structure and fix When, beam column with direction of transfer can vertical bending or formed specified radius circular arc it is curved.

First rotational structure be along beam column triangular loop to be rotatably connected on roll bending device 7 export side rotating bracket 73, and it is connected with the driving device of its rotation of control；Second rotational structure is to longitudinally rotate to be connected to rotating bracket 73 along beam column Connecting plate 74, its rotation is controlled by driving device；Dynamic roller set 71 is connected in the installation through-hole being equipped in connecting plate 74；Beam Column by installation through-hole in dynamic roller set 71, determine to transmit between roller set 72 and transfer roller group 7875.The pendulum of rotating bracket 73 The dynamic telescope motor by being connected to its side is completed, 73 free end of rotating bracket drive with the first about 76 telescope motor and It swings.The rotation of connecting plate 74 acts on realization by being connected to the second telescope motor 77 of 74 control terminal of connecting plate.

The connecting rod 122 that the free end rotation side connection one of rotating bracket 73 is driven by the first telescope motor 76, rotation branch Frame 73 swings different angle as connecting rod 122 moves up and down height, and connecting plate 74 rotates side with the second telescope motor 77 Different rotational angles are controlled, to realize the variation of different roll bending parameters.

The dynamic roller set 71 includes three clamping rollers；Three clampings roller is triangularly arranged respectively, laterally The triangle vacancy that beam column can be made to pass through is surrounded, roller both ends is clamped and is connected in installation through-hole by wheel shaft.

The laterally one side clamping corresponding with three sides of beam column respectively of three clamping rollers of dynamic roller set 71, prevents in roller Due to pressure change segmental arc and the bending parameters of arc linkage section 83 during curved, and by the cambered surface of fixed roll wheel to beam column Positioning reduces the physical injury to beam column roll bending.

It further include that uncoiler and the evener positioned at uncoiler discharge end, the feed end of evener are provided with into feed roller, The discharge end of evener is provided with discharging roller, is provided with transmission between evener discharge end and the feeding end for shaping roller set 9 Roller.By the way that sheet metal uncoiling and smooth processing, the quality after making forming is further consistent.

The present apparatus in use, by sheet metal to be processed be put into forming 9 one end of roller set, by the first roll-in section 21 into Row roughing forms segmental arc 84 so that two lateral edge sheet metal the same side of sheet metal curves inwardly.Subsequently into the second roller Section fining-off is pressed, two segmental arcs, 84 end face keeps rounding top and bottom pattern and moves closer to, and it is convex to form symmetrical two convex portion 81 and two The horizontal segment 82 between part 81 is played, two segmental arcs, 84 end thereof contacts are rolled between two convex portions 81 and horizontal segment 82 Shape has arc linkage section 83, forms the continuous beam 8 of triangle.After continuous beam 8 after forming enters welder 3, roller is pushed 12 to two positioning rollers 13 between protrude into, by the continuous beam 8 after forming be fixed on two positioning rollers 13 and promotion roller 12 it Between, at this point, high-frequency induction welder 10 is successively welded along the contact face of two segmental arcs 84 of continuous beam 8.Continuous beam 8 after welding is Has a blank of connecting column, water cooled case 4 and the rapid cooling air-drying of air-cooled case 5 enhance the bending strength of continuous beam 8 and anti-shearing Power prevents from cutting off the problem of causing bond open or strength reduction with roll bending, improves the quality of finished product.Continuous beam after cooling 8 after pushing roller 12 to be sent to specific position, and laser cutting machine 61 is along two segmental arcs, 84 side vertical cut, and cut surface is from as low as Greatly, it prevents the cutting of two lug bosses uneven, generates burr.Beam column by transfer roller group 7875 after dynamic roller set 71, by dynamic Roller set 71 is mobile relative to roller set 72 is determined in the vertical and horizontal direction, as shown in figure 8, beam column is stretched out along its extending direction The outlet of roll bending device 7 forms differential roller curved arc degree.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, it can be right The technical solution of the utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
