Crankshaft Division of China Vehicle Ziyang Company
has successfully trial-produced two crankshaft blank forging
This marks a major advancement in crankshaft forging technology
optical blank forging is one of the most representative advanced manufacturing technologies for all-fiber crankshaft forging , Its forging is extremely difficult. In 2020, the crankshaft division of Ziyang Company established a crankshaft smooth blank forging technology research and development project team.
When making a traditional crankshaft blank, it is necessary to process both the connecting rod neck ring groove and the main journal ring groove at the same time. The number of ring grooves is large and the size is inconsistent. The innovation of smooth blank forging technology makes it unnecessary to process the main journal ring grooves of crankshaft forgings during blank forming. Although this reduces the difficulty of blank blanking, it increases the forming difficulty of crank forging.
Faced with such a difficult “hard bone”, members of the R&D team of the crankshaft division kept exploring, sorting out, discussing, modifying, and optimizing technical solutions and process design time and time again, conquering one technology after another. Difficulty. The success of
crankshaft smooth blank forging technology not only eliminates the main journal ring groove processing process, increases the blanking efficiency before crankshaft forging by 50%, but also reduces the material specifications and weight of the crankshaft raw materials, effectively improving the utilization of raw materials rate.
At present, crankshaft smooth blank forging technology has begun to be applied to other crankshafts.
