[0002] The trimming disc shear is used to shear the burrs and cracked residues on the side of the hot-rolled steel strip after pressing. The sheared steel strip is coiled to form a strip coil. The two blades of this shearing machine are made into discs and are used to longitudinally shear the edges of steel plates and strips or to longitudinally shear steel plates and strips into narrow strips.

[0003] The traditional trimming disc shear has no transmission device in the disc shear body, and the rotation of the blade is driven by a moving strip steel with a certain tension to achieve tensile shearing. However, this trimming disc shear has shortcomings. First, it cannot improve the shearing efficiency by adding a transmission device; second, it cannot quickly achieve the horizontal displacement of the lower cutter disc and the vertical displacement of the upper cutter disc. Therefore, it is necessary to optimize and improve its structure. Utility Model Content
