摘要
以聚酯型预聚体和MOCA为原料研制了一种冲床弹簧。与金属或普通橡胶弹簧相比 ,用聚氨酯研制的冲床弹簧性能优异 ,质量稳定 ,使用寿命较长 ,冲压零件尺寸精度较高 ,大幅度降低了劳动强度 ,提高了生产效率。
A kind of punching machine spring was developed by using polyester prepolymer, MOCA as raw materials. The spring had outstanding performances, quality stability, long use-life and high tolerance size of punching products as compared with metal spring or common rubber spring. It reduced labour strength, improved production efficiency.
