Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling devices with combined bending and axial displacement units experience torque and frictional forces due to the weight of the displacement device, negatively impacting control behavior, especially with smaller roller diameters.
Innovation Solution
The axial displacement means are arranged with an articulated connection directly or indirectly on the roll stand and roll chock, using a hydraulic piston-cylinder system, with a locking bolt and connecting frame to minimize torque and friction, allowing for improved control behavior and reduced bending force losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the axial displacement means are arranged in a mechanically combined unit with the bending device (as a cantilever arm on guide blocks), then the displacement device can be integrated into the bending structure, but a torque occurs due to the displacement device's own weight, generating frictional forces in the guides that negatively influence control behavior
Solution Approach 1:
The patent divides the previously combined bending and displacement functions into separate mechanical units. The displacement means are no longer integrated as a cantilever arm on the bending device guide blocks, but are instead arranged as an independent system with its own support structure, eliminating the torque problem caused by the displacement device's weight acting on the bending guides.
2Length of stationary object
If the height of the vertical guides of the bending device is reduced, then the overall device height is minimized, but the frictional force generated by the displacement device weight increases, further degrading control behavior
Solution Approach 1:
By separating the displacement means from the bending device structure, the patent eliminates the dependency between guide height and frictional forces. The displacement device now has its own support arrangement, allowing the bending guides to be optimized for their specific function without being burdened by the displacement device's weight, thus maintaining good control behavior even with reduced guide heights.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration minimizes torque in the bending device guides, enhancing control behavior and reducing frictional forces regardless of roll diameter or guide height, thereby improving the overall performance of the rolling device.

AI summary
The invention relates to a roller device (1) comprising at least two rollers, each roller being mounted by means of roll chocks (2) in a roll stand (3), wherein the rollers are provided with axial displacement means (4) for axial displacement in a displacement direction (x), by means of which the rollers may be placed and held in a desired position relative to the roll stand (3), and wherein the rollers are in an operative connection with bending means (5), by means of which a bending momentum may be exerted on said rollers. In order to keep the losses of bending force as a result of the weight of the axial displacement means as low as possible, the invention provides for the axial displacement means (4) to be disposed with a first operative end (6) directly or indirectly on the roll stand (3) by means of an articulated connection (9) on the roll chock (2).
