The invention discloses a feeding device at the front of a bending center, which comprises a fixed base, a C-shaped pressing arm driving device, a C-shaped pressing arm, a rotating positioning mechanism, an auxiliary feeding manipulator, a front-end positioning assembly of a sheet material, and a left-side positioning assembly of the sheet material , the auxiliary pushing assembly on the right side of the sheet, the auxiliary pushing assembly on the rear side of the sheet, and the loading and unloading platform, a feeding device at the front of the bending center of the present invention, through a comprehensive sheet positioning method, the front and left ends of the sheet There are positioning stops, and the right and rear ends of the sheet are equipped with auxiliary pushing mechanisms, so that the positioning of the workpiece is more accurate, and the deviation caused by manual feeding is avoided. At the same time, for some special-shaped workpieces, the secondary positioning of the automatic workpiece can be realized through the mutual cooperation between the positioning mechanisms, which expands the processing range of the workpiece, thereby improving the utilization rate of the equipment.
