Third embodiment: when the long groove plate 8 rotates to be parallel to the conveying belt 2, the limiting strips 4 are inserted into the two groups of conveying mechanisms by the rotating rods 5 at the front end and the rear end of the long groove plate 8, so that the two groups of conveying mechanisms are conveyed together when the rotating rods 5 rotate, the two groups of conveying mechanisms are driven to convey forwards by the cutter plate 22 rotating and shearing once, and thus, the two groups of conveying mechanisms are respectively provided with the thin metal plates with low hardness or thick metal plates and the metal plates with high hardness or thick metal plates with high thickness, so that the two groups of different metal plates can be simultaneously sheared when the cutter plate 22 drives the shearing knife 24 to perform shearing once, and the metal plates on the two groups of conveying mechanisms can be exchanged by separating one sucking disc 45, so that when the cutter plate 22 rotates on the different supporting points 21 at the two sides, the metal plates with high hardness or thick thickness are always positioned on the conveying belt 2 close to the supporting points 21, while the thin metal plate with low hardness or thickness is always on the conveyor belt 2 far from the fulcrum fixing rod 21, so that the effect of bidirectionally feeding and shearing different metal plates is achieved.

Further, the top that conveyer belt 2 is close to cutter board 22 is fixed with support bar 46, can play the effect of support to the metal sheet when cuting through support bar 46, prevents that the metal sheet from falling to because of gravity to influence the shearing effect, can also extrude fixedly the metal sheet when cuting through cylinder etc. can further prevent the metal sheet skew.

The working principle is as follows: when the numerical control type full-automatic plate shearing machine for metal processing is used, a metal plate is conveyed intermittently through the feeding mechanism, and then is sheared through the shearing mechanism, so that the metal plate is sheared.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
