Between cooperate, by its unique structure design, knife rest 3 strength and stiffness of itself are substantially increased, so as to improve
The machining accuracy of lock formula plate shearing machine.The lock formula plate shearing machine of existing structure in shearing, the upper slitter 4 on knife rest 3 by one backward
Power, the power for shearing plate when horizontal component.According to lever principle, rami posterior inferior point 8 is balance pivot, the upper end meeting of knife rest 3
Deflect forward, the torque now acted on caused by the elastic support of front fulcrum 6 on knife rest 3 have to be larger than the generation of level of shear component
Torque and the gravity of knife rest 3 caused by torque sum, otherwise, just occur that knife rest 3 rotates, knife rest 3 can not be with three
Fulcrum keeps contacting simultaneously, and upper slitter 4 can produce gap relative to lower knife 5 and float, and shear effect difference occurs or even can not cut plate
The consequence of material.In order to prevent this situation, the necessary caused sufficiently large active force of the elastic support of front fulcrum 6, so should
The overall structure of front fulcrum 6 must be very big.If the overall structure of front fulcrum 6 is too small, the fragmentation of front fulcrum round roller 602 just occurs,
A series of phenomenons such as it is difficult to shear.Particularly with large-scale gate type plate shearing machine, the 6 integrally-built design of front fulcrum can be extremely tired
Difficulty, because not only horizontal shear component is very big for large-scale plate shearing machine, and in order to ensure that it is also very big that rigid blade holder 3 is conducted oneself with dignity.Applicant
Found by a large amount of field experiments, the deadweight of knife rest 3 can not only be substantially reduced using the knife rest 3 of said structure, and can ensure
Knife rest 3 itself has certain strength and stiffness, so as to simplify the overall structure of front fulcrum 6, reduces manufacturing cost, and one
Determine to prevent in degree and the occurrence of shear effect difference can not even cut sheet material occur because knife rest 3 rotates.
