Problems solved by technology

[0004] The roller straightening machine adopts the non-parallel straightening process, that is, when the movable roller row can be tilted as a whole, it will cause mechanical interference, accelerate the wear of the work roll, and damage the transmission parts. To solve this problem, the split-roll drive technology is adopted, see patent ZL94224750. 7, ZL 95210551.9, ZL 99237340.9, but none of the existing roller straightening machines adopting the split-roll drive technology uses separate lifting guide rollers

Embodiment 1

[0027] Such as figure 1 As shown, 1, 9 are guide rolls, 2, 3, 4, 5, 6, 7, 8 are work rolls. Guide rollers 1 and 9 can be raised and lowered independently. When guide rollers 1 and 9 are in the position shown in the figure, it is an ordinary nine-roll straightening machine. When guide rollers 1 and 9 rise to the upper limit, it is a seven-roll straightening machine. 1, 3, 5, The five rollers 7 and 9 can be raised and lowered together with the movable beam, which is the parallel working mode of the roller row. If the straightening capacity is increased, the load capacity of the work roll system needs to be increased, and one or several combinations of increasing the work roll distance, the work roll diameter, the number of backup rolls, and the load capacity of the backup rolls are comprehensively adopted. If the rectification capacity is not increased, the power of the main motor and the maximum design load of the machine’s force-bearing parts frame, movable beam, fixed beam,...

Embodiment 2

[0029] Such as figure 2 As shown, the work is in the state with the largest number of rolls. The five rollers 1, 3, 5, 7, and 9 in the upper row are tilted with the movable beam as a whole, and all nine rollers participate in the correction work. The main drive adopts the split-roller drive technology, and the main drive is not shown in the figure.

[0030] Such as image 3 As shown, the work is in a state where the number of rolls is reduced. The guide rollers 1 and 9 rise to the limit position and do not participate in the straightening work. The three working rollers in the upper row are tilted with the movable beam as a whole to adjust the opening of the material in and out. At this time, a total of seven rollers participate in the straightening work. The main drive adopts the split-roller drive technology. When the correction load increases, the loads of rollers 2 and 8 become side rollers with small loads, the loads of rollers 3 and 7 increase little or not, and the lo...

Embodiment 3

[0034] If there is no need to increase the straightening capacity of the machine, the load capacity of the work roll system may not be increased, but the power of the main motor and the maximum design load of the machine's stress-bearing component frame, movable beam, fixed beam, etc. may be reduced to save energy, reduce costs or only The power of the main motor is reduced, and the frame, movable beam, and fixed beam are still designed according to the maximum number of rollers, reducing the deformation of the machine's stressed parts and reducing the impact of the machine's elastic deformation on the accuracy of thick plate straightening.

Abstract

The invention refers to a method for enhancing the rectification ability of roll reeler. The method is: 1). the number of rolls can be decreased or reduced; 2). the moving roll row can lift parallel and integral tilt; 3) adopts one or more of increasing the roller spacing of working roll, the roller radius of working roller, the quantity of supporting rollers, the bearing ability of supporting roller. The invention develops the reforming ability and application range.

Description

technical field [0001] The invention relates to a forging equipment for shaping metal materials—a roller straightening machine (such as a roller plate straightening machine), and a method for increasing the straightening capacity of the roller straightening machine. Background technique [0002] In my country's industry standard, the nine-roll plate leveling machine of 25×3200×400Mpa and the seven-roll plate leveling machine of 36×3200×400MPa are two adjacent specifications. Often only the roller plate leveling machine with a larger gear is used. [0003] In the existing roller straightening machine, when equipped with a separate lifting guide roller, the separate lifting guide roller is an indispensable part in the straightening work, responsible for the longitudinal correction of the workpiece, and is responsible for adjusting the feeding and discharging of the workpiece The size of the opening is convenient for the workpiece to enter and make the workpiece vertically stra...
