Still waiting on quotes from Hanna Cylinders, seems a little out there to me for this hydraulic cylinder, I've rebuilt...
We have been using parker cylinders for our hydrualic needs for 10 years or longer, and I personally have always chosen them, because I knew they were a quality cylinder that I could trust to be problem free in the field. That being the case I know we pay alot for the name when we purchase them...
Thanks for input guys, the attached PDF is a blade style that produces decent results. I've seen and tested machines like these many years ago for production, and they did well. This machine will only be used for shearing/splitting pipe into smaller lengths so it can be re-ground and reused...
The blade will be ground from tool steel, the design is basically a hydrualic driven guillotine cutter. I have a ballpark idea of how much force would be needed, based on the largest length of blade contact x depth of cut x shear strength of HDPE. I may try to set up a test cut using a hydraulic...
1.Make a new plane in the center of your shaft.
2.create sketch of profile on new plane.
3.Cut-revolve your sketch, using your existing axis.http://files.engineering.com/getfile.aspx?folder=ba062f3b-f42f-4503-a191-76c9599dd2a6&file=Part1.JPG
I've searched high and low to try and find a formula that would fall under this situation, with no luck. I'm trying to find the force required to push a knife edge blade through a piece of polyethlene pipe, like the hand held plastic pipe cutters. I know how to calculate the force required to...
