Description

Technical field [0001] The present invention relates to diesel engine manufacturing technology, and in particular to a processing device and method for undercut fillet of a crankshaft. Background technique [0002] Generally, in the diesel engine manufacturing industry, the undercut and rounded structure of the crankshaft of the diesel engine can strengthen the crankshaft, that is, improve the fatigue strength of the crankshaft during the pre-processing of the rounded corner rolling process. The quality of the fillet processing has a relatively large impact on the crankshaft rolling process, which in turn affects the fatigue strength of the crankshaft when it is bent. [0003] With the development of society and economy, in the field of diesel engines, the competitiveness of enterprises continues to increase, and people expect to obtain the greatest economic benefits with the lowest cost. At present, in internal combustion engines, most low-power engines use ductile iron crankshaf...
