Abstract
A cold roll forming apparatus for forming a variable profile. The apparatus comprises a forming unit having a least one adjustment stand which includes a roll stand with a pair of rollers between which the sheet metal strip is passed through along its longitudinal direction (X), wherein the roll stand is translationally and rotationally displaceable during the cold roll forming with at least one translatory degree of freedom and one rotary degree of freedom being independent from each other.
Claims11
Apparatus for producing a profile with varying height by means of cold roll forming, said apparatus comprising a forming unit having a least one adjustment stand, the adjustment stand comprising:
- a roll stand including a base plate, a pair of paraxial rolls extending from the base plate and disposed in one plane, and a pair of push rods coupled to the base plate each of the paraxial rolls defining an axis and being rotatable about the axis;
- a gap defined between the pair of paraxial rolls, the gap configured to pass a sheet metal strip therethrough,
- wherein the pair of push rods is configured to translationally displace the base plate with at least one translational degree of freedom and wherein the pair of push rods is configured to rotationally displace the base plate with at least one rotational degree of freedom,
- wherein the base plate is configured to be rotationally displaced by one of said push rods and rotates about an axis of rotation extending paraxially between the axes of the rolls,
- wherein the rotational degree of freedom is uncoupled from the at least one translational degree of freedom.
