精密拉伸冲压件模具保养事项
06-16 / 2023

1、定期对精密拉伸五金冲压件冲床的转盘及模具安装底座进行检查,以确保上下转盘的同轴精度。

2、精密拉伸五金冲压件安装使用前应需要严格检查,并且清除脏物,仔细检查拉伸冲压件的导向套和模具是否润滑良好。

3、为了保证精密拉伸五金冲压件的使用寿命,还应定期对模具的弹簧进行更换,防止弹簧疲劳损坏影响拉伸冲压件使用。

4、冲压人员在安装模具时应使用较软的金属(如铜、铝等)制成操作工具,防止安装过程中敲、砸时损坏拉伸冲压件。

5、精密拉伸五金冲压件的凸模和凹模刃口磨损时应及时停止使用,及时刃磨,否则会迅速扩大模具刃口的磨损程度,加速模具磨损,降低冲件质量和模具寿命。

6、按照模具的安装程序将凸凹模在转盘上安装好,保证凸凹拉伸冲压件的方向一致,特别是具有方向要求的(非圆形和正方形)拉伸冲压件更要用心,防止装错、装反。

 精密拉伸五金冲压件的使用寿命,除了取决于合理的模具结构,超高的制造精度,良好的处理效果以及正确地选用冲床、拉伸冲压件安装精度等因素外,模具的正确使用、保养和维护也是不可忽视的环节。
