a shear edge of a circle shear comprises a flying shear body, a matching hole, a chamfer and a positioning hole, wherein the matching hole is formed in the middle of the flying shear body; chamfers are arranged on two sides of the matching hole; the locating hole be provided with four, the equipartition is in the outside of mating holes.
As a further technical proposal of the utility model, the diameter of the flying shear disk body is 500 mm; the diameter of the matching hole is 327 mm.
As a further technical proposal of the utility model, one side of the matching hole is provided with a fixed groove; the radius of the fixed groove is 16 mm.
As a further technical scheme of the utility model, the size of chamfer be 3X 45, the mating holes is installed through chamfer and cooperation axle, has great fit clearance, can prevent to appear the interlock effect between flying shear disk body and the cooperation axle.
As the utility model discloses a further technical scheme, every the central line of locating hole be 198.5mm apart from the central line of mating holes, a plurality of locating holes are fixed the flying shear disk body simultaneously through the screw, fixed reliable, and the atress distributes evenly.
As a further technical scheme of the utility model, the flying shear disk body the outside seted up the flying shear sword cooperation groove of being convenient for cutting edge cooperation installation, assemble the cutting edge to flying shear sword cooperation groove, simple structure, easy dismounting appears wearing and tearing serious back when the cutting edge, can in time change.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses, the mating holes is installed through chamfer and cooperation axle, has great fit clearance, can prevent to appear the interlock effect between flying shear disk body and the cooperation axle, every the central line of locating hole be 198.5mm apart from the central line of mating holes, a plurality of locating holes are fixed the flying shear disk body simultaneously through the screw, fixed reliable, and the atress distributes evenly, the flying shear sword cooperation groove of being convenient for cutting edge cooperation installation is seted up in the outside of flying shear disk body, assembles the cutting edge to flying shear sword cooperation groove, simple structure, easy dismounting, after the cutting edge appears wearing and tearing seriously, can in time change.
