7. the feeding servo motor 300 drives the feeding ball screw 307 to move, the slide carriage 306 drives the feeding beam 310, and accordingly the floating clamp 312 is driven to move backwards in the track space 316 to the rear end of the feeding table surface 313;

8. repeating the work of the processes 3-7, wherein the plates are clamped by the floating clamp 312 and are fed forwards by matching with the feeding beam 313, and the left and right positioning of the plates is carried out by the rear stop 309 and the front stop 308, so that the plates with continuous plate surfaces are continuously conveyed forwards along the feeding carrier roller 302 and the feeding table surface 313;

9. when a sheet material moves in the longitudinal direction of the feeder bed 301 and deflects, the front stop 308 and the rear stop 309 generate lateral acting force on the sheet material deflection, the swing component 321 of the floating clamp 312 drives the eccentric wheel 320 to rotate along the middle shaft, left-right floating is realized through the spring plunger 322, the second spring plunger 325, the guide rail 323 and the slide block 326, the lateral acting force of the front stop 308 and/or the rear stop 309 on the sheet material is automatically eliminated, the deflection of the sheet material in the feeding process is automatically corrected, the sheet material is limited in a determined position on the feeding table surface 313 again, and the sheet material is prevented from being curled in the feeding process.

Compared with the defect that a common feeder needs manual feeding and has low production efficiency, the flexible sheet metal production line feeder provided with the floating clamp has the advantages that a steel plate is clamped by the feeding cross beam and the floating clamp to feed forwards, the plate is positioned leftwards and rightwards by matching with the rear stopper and the front stopper, feeding is completed by driving a feeding ball screw by a feeding servo motor, the positioning precision is high, and automatic feeding is realized; because the floating clamp can float left and right, the feeding deflection can be automatically corrected, the rejection rate of sheet metal production and processing is greatly reduced, the production efficiency is improved, and the transformation and the upgrading of a common feeder are realized.
