Fig. 5 is the sheet material contour curve figure that utilizes moulding of the present invention.The present invention adopts the monolateral irregular section of make-up machine moulding of 12 passages (promptly 12 groups symmetry rolls), the contour curve figure on its variable cross-section limit as shown in Figure 5, desire is molded into 80 degree with the variable cross-section limit from 0 degree.The distance that adjacent two passage molding roller frames are 12 is 500mm (being the distance between the engaging-in end of two adjacent groups molding roller 14).The side (downside as shown in Figure 5) that cross section profile changes during the sheet material charging enters molding roller, and the immovable side of cross section profile (upper side edge as shown in Figure 5) enters auxiliary roller.The servomotor 1 that is installed on molding roller frame 12 main shafts drives 28 rotations of molding roller axle, and then drives molding roller 14 rotations that are installed on the molding roller axle 28.Molding roller 14 drives sheet material by friction and advances, simultaneously auxiliary roller 15 another side of pushing down sheet material prevent that sheet material from swinging in forming process, deflection and influence formed precision.In forming process, the servomotor 1 that links to each other with precision ball screw 24 drives precision ball screw 24 and rotates, driving precise ball screw pair 23 moves on precision ball screw 24, thereby realize that moulding roll stand 12 is laterally moving the monolateral variable cross section when realizing plate forming down along sheet material on the precise guide rail 21.Molding roller frame 12 depends on sheet material contour shape and sheet material charging rate along the horizontal displacement of sheet material.As the sheet material profile is conic section y=ax
2The part of+bx+c, the sheet material Δ x that whenever advances on feedstock direction then at the horizontal feeding increment of molding roller frame 12 is
Meanwhile, be connected servomotor 1 on the rotating shaft 9 and drive and go up rotating shaft 9 and rotate, following rotating shaft 17 is driven, thereby drives 12 rotations of molding roller frame.The angle of rotation is also relevant with the sheet material charging rate with the roll contour shape.As the sheet material profile of above-mentioned conic section, the sheet material Δ x that on feedstock direction, whenever advances then, the corner increment of molding roller frame 12 is Δ θ=arctan (2ax
N+1+ b)-arctan (2ax
n+ b).By synthesizing of moving along the horizontal feeding of sheet material and roll along three of the rotations of profile of the advancing of sheet material, roll on the section bar longitudinal direction, realizing continuously changing of cross sectional shape, realize three-dimensional one-sided variable-section roll-bending moulding.
Desire is molded into 80 degree with sheet material variable cross-section limit from 0 degree, except that the roll of design specialized roll shape, considers the concrete condition of profiled member, might need to make the axis of each passage molding roller from the horizontal by certain angle.In this example, the angle of the molding roller axis of the make-up machine of 12 passages and horizontal direction is respectively-10 degree ,-10 degree, 0 degree, 10 degree, 10 degree, 20 degree, 30 degree, 30 degree, 40 degree, 50 degree, 50 degree and 60 degree.Guide runner 27 is fixed on the molding roller frame 12 by screw, and makes molding roller frame 12 to slide along the chute on the rotation riser support 10, thereby adjusts the angle of moulding roll axis and horizontal direction.Before moulding began, the angle of molding roller axis and horizontal direction will be adjusted to required angle, with screw molding roller frame 12 was fixed on the rotation riser support 10 then.In forming process, this angle no longer changes.
When sheet material enters next passage by certain passage, the action of a time make-up machine before the make-up machine of this passage repeats, with carrying out smoothly of assurance forming process, and reshaping 10 is spent angles on the basis of preceding a time forming angle degree.The roll profile difference has guaranteed angle and the shape that every time make-up machine moulding is different, but the moulding track of each passage make-up machine motion is identical, and just the time of each passage forming moving goes up according to the spacing distance between every time of space and postpones.
The above only is a preferred implementation of the present invention; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
