The following describes the course of work and the principle of camber straightener of the present invention.
The metal blank that has camber was detected the direction and the size of camber automatically by aided measurement device before entering this camber straightener.In the plate traveling process, at first enter in the middle of the left and right sides smoothing roll group that is made of smoothing roll 2 in the straightening mechanism, under the driving of transposition engagement positions 3 on the throne, smoothing roll 2 utilizes the annular groove contact plate in the middle of the roll body, but does not force plate generation lateral displacement.
Plate moves on, and enters in the middle of the roller of the leveling up and down group that is made of leveling roller 5 in the leveling mechanism.Under the driving of leveling roller 5 transposition engagement positions 6 on the throne, make plate pass through that the bending of S type takes place when the leveling roller is middle up and down at this moment.Because leveling roller group One's name is legion is generally 8 to 20 groups, the huge frictional force between leveling roller group and the plate has limited the lateral displacement of metal blank in traveling process, forces plate generation lateral displacement for smoothing roll in the straightening mechanism 2 fixed pivot is provided.
When the plate head was about to arrive the leveling mechanism other end, leveling roller group was to the lateral displacement control maximum of plate.This moment, displacement adjusting device 3 drove movable slider 4 under the effect of control system, drove smoothing roll 2 and forced plate that the lateral displacement opposite with the camber direction takes place.Leveling roller group make plate take place the bending of S type also help eliminate plate since side direction force crooked produce stress internal stress, help aligning the plate camber, improve the plate flatness.
All arrange straightening mechanism as leveling mechanism both sides, after plate comes out from the leveling mechanism other end, continued to enter the straightening mechanism of opposite side.The smoothing roll of this side straightening mechanism blocks slab edge by the concave groove of roll body immediately, force plate that the lateral thrust opposite with the camber direction takes place, make the short slightly side generation plastic elongation distortion of plate lengthwise edge, thus the side direction camber of aligning plate.When the plate tail end entered leveling mechanism, leveling roller group reduced gradually to the control of plate lateral displacement, and straightening mechanism stops the side direction of plate is forced crooked, and the aligning process finishes.
The aligning process of whole plate camber begins after plate enters complete leveling mechanism, carries out in the plate traveling process, and finishes when plate begins to withdraw from leveling mechanism.Make plate that the bending of S type take place in the horizontal direction by leveling roller group, by huge frictional force, the lateral displacement of restriction plate.Be the perverted fixed pivot of plate with leveling mechanism like this, it is fixing point with the centre at leveling mechanism place that the straightening mechanism of rear and front end just can be forced plate, makes the plate both sides that lateral thrust take place.Make the edge generation plastic elongation distortion of the stressed side of plate like this, reach and the approximately equalised length in plate opposite side edge, thus the original camber of aligning plate.
The patent that the applicant applied in the past, cardinal principle are the compression by thickness direction, make length direction generation plastic elongation distortion, and be relatively more responsive to thickness deviation, and to sheet thickness less than 7mm, camber during greater than 15mm, operating efficiency is not high.The method for aligning of straightener of the present invention is directly to force the plate side direction that the lateral thrust opposite with original camber takes place, force the short slightly lateral edges generation plastic elongation distortion of plate, make plate produce lateral thrust largely easily, therefore can align camber largely.This aligning principle is wide to the sheet thickness range accommodation, and is insensitive to thickness deviation, overcome the deficiency of camber straightener in the prior art.
