高速压力机滑块下死点动态精度超差的解决措施

Solution to poor dynamic accuracy of down dead point of high speed press

根据J75G 60型 60 0kN高速精密压力机在高速冲压条件下下死点动态精度超差的实际 ,分析了精度超差的原因 ,采取了相应的措施 ,使下死点动态精度由± 5μm提高到± 2 μm以内 ,效果明显。

Obvious improvement of down point dynamic accuracy from ±5μm to within ±2μm has been obtained by reducing mass of reciprocating motion components and symmetric arrangement of complete dynamic balance device of crank link mechanism based on analysis of poor accuracy causes and practical conditions of poor dynamic accuracy of down dead point of Model J75G 60 600kN high speed precision press.
