Description

Technical Field

[0001] The invention belongs to the technical field of forging grinding, and specifically refers to a deburring device for forgings. Background Art

[0002] A forging is an object in which metal is subjected to pressure and shaped by plastic deformation or a suitable compressive force. Deburring is to remove the spurs or flash formed at the intersection of the surfaces of the part. The harm of burrs is particularly obvious. During the production process of forgings, they need to be repeatedly hammered, and many burrs will protrude on the outer surface of the forgings. These burrs must be removed in time, otherwise it will affect the quality of the forgings. For ring forgings, it is necessary to remove the burrs at the edges of the inner and outer circles of the ring forgings, and the ring forgings need to be flipped. The processes are numerous and the operation is cumbersome. Moreover, when workers come into contact with the forgings, they are easily pricked by the burrs.
