Abstract
The common causes caused by equipment wear,tooling wear,processing accuracy of forging die,installation specification and shifting force and the mechanism of mismatch was analyzed,and the five kinds of problems were checked and solved respectively by checking the press rail clearance and fit clearance between the guiding rod and guide sleeve with plug gauges,checking the accuracy of die with three coordinate measuring machine, formulating the installation specifications of die and optimizing the design of die.These measures play an important role in the production practice and the improvement of the forging's quality.关键词
