TIP: Spring models for import

Just thought some would be interested:
Century Spring (www.centuryspring.com) has a VERY comprehensive
searchable catalog, and the results can be downloaded in IGES format.
They have four sorts of springs in their searchable database
(compression, die springs, extension and torsion) and at least for
compression springs it works extremely well. For example, with
compression springs and for a number of variables (i.e., OD, ID, free
length, spring rate, solid height, wire diameter, type ends, material,
finish, total coils, and a couple more) you can specify a RANGE of
values, a GREATER THAN value, a LESS THAN value, or you can leave
undefined. Once you've defined enough parameters to satisfy you, hit
the Search button, and it will come up with all the springs that they
have that will satisfy those parameters, with all parameters listed in
tabular form so it's easy to compare. The fewer parameters you enter,
the greater number of returns from the database. If you find a spring
you like and want to download a CAD model you get to specify the format
(IGES for SolidWorks is the logical choice), and then you'll have to
specify the length of the spring in constrained state (however you
happen to be using it in your model). You'll get a ZIPped IGES file
that imports just fine into SolidWorks and will fit where you want it to
fit. It's an Imported solid, obvously, so there are no different
configurations you can create, but at least you can show the spring as
it actually would appear where you're using it. Lots quicker than doing
helical sweeps and especially better than creating the transition to a
closed end spring or a closed-and-ground end spring . . . with the added
benefit that you know the spring actually exists and can be ordered.

Thanks Spork, that will come in handy.
BTW, will we see you at SWW this year?

As usual, I can't afford it. Being self-employed I have nobody to pay
the bill for me, other than my "boss", and she's a tough nut to crack.
Especially as she wants to go on a junket to New York City her very own
self.

 

Well, as we both know keeping "the boss" happy is job 1.
