I finally started to own a hydraulic press

[a smile]

Imperial tons vs metric tonnes! 86.52/1.1=78.65

Forgot about that ….
Thanks!

Thanks to the support of my two friends, I finally understand that my calculation is correct, and our calculation results are basically the same, only the problem of unit conversion.

Looks like the seller got the model wrong. I just don't know if he meant it or not.

I can finally get back to assembling my hydraulic press. Today, we simply assembled a test circuit, used a contactor, and a control box, and now we can do some simple hydraulic action tests.

I think this is a very rough hydraulic cylinder, and the push rod is not electroplated? And it has been rusted, I carefully use fine sandpaper to remove the rust and apply lubricating oil, fortunately, it can still be used.
First make a hexagonal mold, and then heat the cylinder after stamping, the result is forming or good, but, because there is no fixed tooling, so the pressure is crooked!

The overall conclusion is that it is fully competent for the work, and I will make a complete tool in the future.

要开始制作液压机的装模机，车床是最重要的工具，幸运的是我的车床是完美的机床。

This is the replaceable clamp to be loaded on the hydraulic rod. I am not a professional mechanical engineer, so I can only make some parts according to my own needs, hope that a professional stamping engineer can give some advice!

I used DECKEL to drill holes and make some flanges by dividing the circumference 6 equally.

Tap and chamfer on the flange.

Drill holes and taper wires on the push rod of the hydraulic press. Then install the finished flange, and use it to install the stamping assembly, as well as the mold!

In order to make a working face, a lot of time is spent cutting holes and cutting semicircular holes.

Flat to the face, I want the hole to be completely concentric with the cylinder. Unfortunately, it was difficult to do, and I had to make another auxiliary shaft to assist the concentric work, which took a lot of time, which made me wonder if the time I spent on this device was worth it.

parallel to the steel plate and concentric with the center hole? It's all I can think of right now, it's all I can think of right now, it's just too much trouble.

After leveling the iron plate, weld the front and back sides, and now you have a perfectly working plate!

 

[a smile]

Punch holes for the mold fixed flange, and punch holes for the bottom plate to make threads, and use screws to fix!

在液压机的工作面上安装一个旧卡盘来固定冲压件。

首先将后置安装改为前置安装

使用CNC加工等分孔和沉头孔。
