After the steel plate is bent once, the position A2 of the supporting structure of the steel plate supporting mechanism 3 required to be lifted by the initial height A1 can be obtained according to the value B2 of the steel plate bending once, the value D1 of the angle and the value C1 of the initial interval, and the height of the steel plate supporting mechanism 3 required to be lifted after the steel plate is bent many times can be automatically calculated according to the method.
When the supporting structure of the steel plate supporting mechanism 3 is controlled to ascend, the output end of the second hydraulic cylinder 313 is controlled to extend out and quantitatively ascend on the second lifting rail 12 together with the second rail sliding table 311, so that the bearing roller 322 is gradually close to the steel plate and finally contacts with the bottom end of the steel plate.
Before the bearing roller 322 contacts with the steel plate, the suction cup mounting box 332 arranged on the arc-shaped rotating arm 331 elastically supported by the first torsion spring 3311 can firstly contact with the steel plate, and under the elastic supporting effect of the second torsion spring 3312, one side edge of the suction cup mounting box 332 contacts with the steel plate, and the suction cup mounting box 332 starts to rotate on the arc-shaped rotating arm 331 along with the continuous rising of the height of the steel plate adsorption mechanism 33 until a plurality of suction cups 333 arranged on the suction cup mounting box 332 are fully attached to the surface of the steel plate, and after the bearing roller 322 of the steel plate supporting structure 32 contacts with the steel plate, an external air source is controlled, so that the suction cups 333 can be adsorbed at the bottom end of the steel plate.
The second inclined arm 3122 extends into the directional sliding frame 3121 to reduce or increase the distance between the bearing roller 322 and the bending frame 1, so as to support the steel plates with different lengths, and the distance value C1 can be synchronously adjusted, then the initial extending length of the second hydraulic cylinder 313 needs to be controlled to be unchanged so as to ensure that the value of A1 is unchanged, and after the second inclined arm 3122 is adjusted, the positioning bolt 3124 on the directional sliding frame 3121 can be screwed into the corresponding positioning hole 3123 on the second inclined arm 3122 to fix.
Since the steel plate suction mechanism 33 is brought into contact with the steel plate before the steel plate support structure 32 supports the steel plate, the angle of the arc-shaped rotating arm 331 of the steel plate suction mechanism 33 is moved before the steel plate support mechanism 3 is lifted to any height to support the steel plate.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this application will occur to those skilled in the art, and are intended to be within the spirit and scope of the application.
