[0002] A shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. Specifically, a reasonable blade gap is set between the moving upper blade and the fixed lower blade to apply shear force to metal plates of various thicknesses, so that the metal plates are broken and separated according to the required size.

[0003] In the prior art, Chinese Patent Publication No. CN213945107U discloses a front positioning shearing tool for a shearing machine and a shearing machine, which belongs to the field of feeding technology for a shearing machine. The front positioning shearing tool for a shearing machine includes: at least two support frames arranged in parallel; at least two track assemblies, each track assembly includes a track body corresponding to the support frame, and at least two positioning stops corresponding to the track body, which rotate the positioning stops to press against the sheet to be sheared. Technical effect: The roller can assist in the feeding of the sheet to be sheared, which is more time-saving and labor-saving, and the roller has a single rotation direction, has good guiding properties relative to the ball, and has higher guiding accuracy, reduces the position deviation of the sheet to be sheared, improves the shearing accuracy of long pieces, and improves the working efficiency and safety.
