Swivel lock feature which allows blades on shears to separate
Swivel lock feature which allows blades on shears to separate
(OP)
Hello,
I am designing a trauma shear for the company that I work for and we are wanting to utilize a swivel lock to allow the blades to separate for cleaning.
i.e. https://shun.kaiusa.com/shun-kitchen-shears.html ; https://www.cutco.com/products/product.jsp?item=su...
I have been working with a factory in China to design and manufacture this component but they have been able to provide me with a quality prototype.
I am pretty savy in SolidWorks so I have take the initiative to design it myself. I am basing the design off the Shun kitchen shear. I have completed the shank of the swivel lock as well as the locking interface on the blade (see picture 1 below). And now I am trying to figure out how I will secure the shank to the blade. I do not understand hardware used on the Shun. Can anyone provide insight based on the 2nd picture below?

and the view with the nut is a different type where the tang has a thread on it, for the nut, as hydtools says to tighten the blades.
you might get teh same result with an internally threaded hole in the tang.
buy the second pic and have a look.
another day in paradise, or is paradise one day closer ?

the 2nd (cutco) one may not have a tang, but just an externally threaded post, with some seat to locate the 2nd shear.

The T-post is press fit into the blade, and also threaded on the bit that protrudes. The nut is there so that as the pocket in the female blade wears over time, you can turn the nut to pull the T-post through the blade a little at a time and re-tighten the fit when it becomes loose.
