前几天,因为需要制作一些六角工具,所以买了一个很差的冲柄,只用了一次,就坏了。

后来即使用MT4锥柄改造冲床手柄也损坏过一次,我总结了大概的故障原因,然后开始制作偏心冲床。

最远端使用小滚珠轴承(内/外径9/26),然后是圆锥滚子轴承20/42,然后是滚珠滚珠轴承20/42。
然后,我制作了另一个类似结构的更大手柄,使用更大的手柄,并且还优化了轴承的组合。轴承内外径:9/26;25/52;25/52..


试验结果:由于轴承组合结构不合理,小工具手柄很快损坏。

为了节省材料,我用了两段不同直径的钢材,用车床加工成紧密配合的尺寸。

使用液压机将其压在一起

Beautiful work sir. A rotary broach is high on my list of things I want to make this winter, albeit a smaller one than yours.
I would like to say two important points in my actual operation: 1. Deflection Angle, I initially made 1.05 degrees, in the actual operation, the small pallet was 0.5 degrees off, so the actual deflection Angle I used was 1.65 degrees. 2. Bearing selection should focus on axial strength, so I will re-optimize the bearing configuration in the future production.
