Because the cutting edge is skillfully arranged, the metal plate to be cut can be cut into five pieces at one time when the upper tool apron main body slides downwards, the operation and the rotation of workers for multiple times are not needed, the work of cutting into five pieces at each time can be completed only by intermittent feeding, and the work efficiency is improved.

The further technical scheme is that the number of the cutting edges is nine, the projection shapes of the nine cutting edges on the horizontal plane are in a shape of horizontal and longitudinal end-to-end connection, and each cutting edge is obliquely arranged relative to the horizontal plane. After the arrangement, the cut-off square-wave-shaped notch is formed in the sheared metal plate after the upper tool apron main body descends, and with the feeding of the metal plate to be sheared, the upper tool apron descends once every time the metal plate is fed, and five rectangular plates can be cut off every time.

The technical scheme is that three of nine blades are arranged close to the metal plate to be cut, two blades are arranged far away from the metal plate to be cut, the three blades arranged close to the metal plate to be cut are arranged in the same vertical plane, and the two blades arranged far away from the metal plate to be cut are arranged in the other vertical plane parallel to the previous vertical plane.

The technical scheme is that the inclination directions of two blades at two ends of three blades close to the blades arranged on the metal plate to be cut are opposite; the two blades far away from the metal plate to be cut are opposite in inclination direction.

The technical scheme is that the two blades at two ends of the three blades close to the to-be-sheared metal plate are inclined upwards gradually along the edge of the multi-blade shearing machine towards the center of the multi-blade shearing machine, and the two blades far away from the to-be-sheared metal plate are inclined upwards gradually along the edge of the multi-blade shearing machine towards the center of the multi-blade shearing machine. The inclined direction can avoid the danger that the sheet material is tilted or flies out after being cut when the metal sheet material is cut, and the force after the cutting is towards the central direction of the multi-blade cutting machine.

The technical scheme is that four parallel blades are arranged between three blades close to the metal plate to be cut and two blades far away from the metal plate to be cut, every two blades are in one group, two blades in each group are respectively arranged at two ends of the two blades far away from the metal plate to be cut, and two blades in each group are obliquely arranged with the horizontal plane and are obliquely inclined upwards and downwards along the feeding direction of the metal plate to be cut. The plurality of blades arranged in the middle gradually shear the metal plate when the metal plate is sheared, so that the shearing work is facilitated, the blades can be prevented from being damaged, and the service life of the blades is prolonged.

The further technical scheme is that the driving mechanisms are hydraulic cylinders and four hydraulic cylinders are arranged. The four hydraulic cylinders are arranged in a group in pairs, and the four hydraulic cylinders simultaneously act on the upper tool apron main body downwards, so that the balance is improved, and the unbalance loading is avoided.

The utility model has the advantages and beneficial effects that: by improving the form of the upper tool apron of the multi-blade shearing machine with the upper tool apron and matching with the lower tool structure of the multi-blade shearing machine, the metal plate to be sheared can be directly cut into five pieces, the processing is finished at one time, the shearing efficiency is improved, and the operation times and labor intensity of workers are reduced. Because the cutting edge is skillfully arranged, the metal plate to be cut can be cut into five pieces at one time when the upper tool apron main body slides downwards, the operation and the rotation of workers for multiple times are not needed, the work of cutting into five pieces at each time can be completed only by intermittent feeding, and the work efficiency is improved. The upper tool apron body is lowered to form a square-wave-shaped notch on the sheared metal plate, and with the feeding of the metal plate to be sheared, the upper tool apron is lowered once every time the metal plate is fed, and five rectangular plates can be cut out every time. The inclined direction of the blade can avoid the danger that the sheet material is tilted or flies out after being cut when the sheet material is cut, and the force after being cut is towards the central direction of the multi-blade cutting machine. The middle blades gradually shear the metal plate when shearing the metal plate, so that the shearing work is facilitated, the blades can be prevented from being damaged, and the service life of the blades is prolonged.
