Be provided with hydraulic pressure chamber in the pedestal 1, hydraulic pressure chamber includes first cavity, middle cavity and second cavity, and wherein first cavity and the equal vertical setting of second cavity, their upper end all communicate mesa 11, and cavity in the middle of their lower extreme all communicates. And the first cavity is closer to the cutter assembly 3 than the second cavity, i.e. the first cavity is located between the second cavity and the cutter assembly 3.

A top plate 2 is arranged above the table top 11, and the top plate 2 is used for installing and connecting equipment parts required to be arranged above the table top 11.

The knife assembly 3 comprises an upper knife 31 and a lower knife 32, wherein the lower knife 32 is fixedly connected with one end of the table-board 1, and the edge of the lower knife 32 faces upwards and is flush with the table-board 11. The upper blade 31 is disposed on the side of the lower blade 32 close to the pedestal 1 with the blade edge of the upper blade 31 facing downward. The upper knife 31 moves downward to cut the sheet 8 alternately with the lower knife 32.

The cutting power assembly 4 comprises a lifting mechanism 41, a linkage part 42 and a guide rod 43, the lifting mechanism 41 is fixedly arranged on the top plate 2, and a power output end of the lifting mechanism 41 faces downwards vertically and is fixedly connected with the upper knife 31 and the guide rod 43 through the linkage part 42 to synchronously drive the upper knife 31 and the guide rod 43 to do lifting movement. The lifting mechanism 41 can adopt common power components such as an air cylinder, a hydraulic oil cylinder, an electric push rod and the like to drive the upper knife 31 to move up and down to cut the plate 8.

The hydraulic transmission assembly 5 comprises a first piston 51, a second piston 52, a lift 53 and a transmission fluid 54. The first piston 51 is arranged in the first cavity and is in sealing sliding connection with the inner wall of the first cavity, the first piston 51 is also fixedly connected with the guide rod 43, and the guide rod 43 can drive the first piston 51 to move up and down along the first cavity. The second piston 52 is arranged in the second cavity and is in sealing sliding connection with the inner wall of the second cavity, the lifting part 53 is arranged in the second cavity, the lower end of the lifting part 53 is fixedly connected with the second piston 52, and the upper end of the lifting part 53 faces the table board 11. The transmission fluid 54 fills a part of the hydraulic chamber surrounded by the first piston 51 and the second piston 52, and the transmission fluid 54 generally adopts hydraulic oil commonly used in hydraulic transmission, so that the lifting motion of the first piston 51 can be transmitted to the second piston 52 through the transmission fluid 54 to drive the piston 52 to lift.

When the plate 8 is placed on the table 11 to be cut, as shown in fig. 4a, the plate 8 extends between the upper knife 31 and the lower knife 32, the upper knife 31 moves under the driving of the lifting mechanism 41, and the plate 8 is cut by the lower knife 32 which is ready to be fixed.

When the conventional plate shearing machine shears, as shown in fig. 4b, the part of the plate 8 located outside the table top 11 is pressed by the upper knife 31 ', and the plate 8 and the table base 1 ' form a structure similar to a lever, and the supporting point of the lever is the side edge of the table top close to the lower knife 32 '. Because most of the mass of the plate 8 is located on the side of the lever structure far away from the lower knife 32 ', and the contact area between the upper knife 31' and the plate 8 is small, the pressure applied to the plate 8 by the upper knife 31 'is small, the plate 8 cannot rotate around the supporting point against the self-gravity, and the plate 8 cannot keep self-rigidity during cutting, and is bent and deformed under the action of the upper knife 31' at the cutting section, namely, a curled edge is formed.

When the plate shearing machine is used for shearing the plate 8, as shown in fig. 4c, the guide rod 43 and the upper knife 31 synchronously move downwards during shearing, the guide rod 43 drives the first piston 51 to move downwards along the first cavity, the second piston 52 is pushed to move upwards along the second cavity through hydraulic transmission of the transmission liquid 54, the lifting part 53 moves upwards along the second cavity until the plate protrudes out of the table top 11, one side of the plate 8, which is far away from the knife assembly 3, is jacked, the side of the plate 8 is tilted and rotates around a supporting point of the lever, and therefore the plate 8 can be prevented from being bent and deformed to form a curled edge on a shearing section. And preferably, in order to increase the force bearing area of the supporting point, a slope facing the lower knife 32 is preferably formed on the side of the table top 11 facing the lower knife 32, and the inclination angle of the slope is adapted to the tilting angle of the sheet material 8.

Because this plate shearing machine is when cuting panel 8, panel 8 can incline, in order to avoid panel 8 to slide, can fix panel 8 when cuting better, avoid panel 8 to appear sliding. Therefore, a roller assembly 6 is preferably arranged right above the lifting portion 53, the roller assembly is suspended on the top plate 2 through an elastic member 7, the upper end of the elastic member 7 is fixedly connected with the top plate 2, the lower end of the elastic member 7 is fixedly connected with the roller assembly 6, and a space for the plate 8 to pass through is formed between the roller assembly 6 and the table top 11.

When the sheet material 8 is placed across the table 11, the roller assemblies 6 roll to facilitate the passage of the sheet material 8. When shearing is carried out, the lifting part 53 moves upwards to clamp the plate 8 with the roller assembly 6, so that fixation is realized. For more firm fixation, the lifting part 53 is made of a magnet, and the roller assembly 6 is made of a magnetic substance capable of being attracted by the magnet, so that a magnetic force is generated between the lifting part 53 and the roller assembly 6 to further clamp the plate 8.
