Description

Technical Field

[0001] The present invention relates to the technical field of forging processing, and particularly relates to a forging flash cutting device. Background Art

[0002] For a certain type of shaft forging produced by our factory, during the forging production process, flashes will be generated on both end faces of the shaft forging. The conventional method for removing the flashes is as follows: after the shaft is cooled to room temperature, workers hold a grinding machine to grind off the flashes on the two end faces in sequence. This processing method has the following disadvantages: completely relying on grinding to remove the flashes will consume a large amount of time, the processing quality of manual grinding varies from person to person, there are differences, and the grinding difficulty will also increase after the shaft is cooled.
