Embodiment Construction

[0028] exist Figure 1A and Figure 1B An embodiment of a device for flexible roll forming is shown in , which guides and squeezes a strip 1 along a strip feed direction X between a plurality of forming rolls 11 such that the strip 1 The forming rollers 11 are deformed by pressing against each other and thereby produce a top surface 2 , a side surface 3 and a bottom surface 4 . The profiling rolls 11 are held in their respective positions and driven in each case by an associated actuator 10 with a corresponding motor 12 , wherein the profiling rolls 11 rotating about their respective axes press the strip 1 and run with it. Or preferably also driven by the motor 12 .

[0029] The corresponding position and orientation of the forming roll 11 and the motor 12 connected thereto and the partial actuators are brought about in the form of actuation by corresponding actuators 10 , whereby the actuators 10 can be rotated in the transverse direction Y, in the vertical direction Z and a...

Abstract

The invention relates to a method for generating an optimized 2D or 3D roller profile curve (5), having a prescribed desired 2D or 3D roller profile curve (5) of a roller profile (5) that changes along a rolled material feed direction (X) and actuating a flexible roller profile device, in which profiling rollers (11) can be adjusted in a computer-controlled manner during a roller profiling process. The method for generating the optimized 2D or 3D roller profile curve comprises the following: a) entering the desired 2D or 3D roller profile curve (5) by means of CAD tools; b) calculating the optimized 2D or 3D roller profile curve (5) from the input and desired 2D or 3D roller profile curve (5) using rounding algorithms, wherein the rounding algorithms round off the 2D or 3D profile curves (5) at a substantially constant curvature, so that the optimized 2D or 3D roller profile curve (5) is generated accordingly, substantially avoiding an uneven curvature; c) confirming or modifying a region of the optimized 2D or 3D roller profile curve (5); and d) saving the optimized 2D or 3D roller profile curve (5).

Description

technical field [0001] The invention relates to a method for generating an optimized 2D or 3D roll profile for a corresponding plant, wherein the roll profile curvature is continuously rounded and thus reduces the need for adjusting the forming Acceleration forces of the rolls and actuators and enable correspondingly higher material feed rates. The method includes a corresponding curvature-continuous rounding algorithm, which is either integrated in a CAD tool for generating an optimized 2D or 3D rolling profile profile, or which can also be used for flexibly rolling Electronic front connections for roll-formed equipment ( ), the front connecting device converts the preset, non-optimized 2D or 3D rolling profile curve with conventional abrupt curvature changes into an optimized, continuous curvature 2D or 3D rolling profile curve . Background technique [0002] Known prior art is the production concept of a rolling profile with a constant cross section along the rolling ...
