12V Push Mechanism
12V Push Mechanism
(OP)
I am in need of a 12V DC device that can push with at least 6 pounds of force.
Does anyone have ideas on the cheapest way to accomplish this?
Greatly appreciate any input.

Do you know of any push type solenoids that would provide this type of force?

RE: 12V Push Mechanism
Solenoids have narrow strokes of peak force. http://www.farnell.com/datasheets/1701736.pdf
Voice coil actuators will have more liner force profile but are expensive. http://www.moticont.com/voice-coil-motor.htm
Linear actuators usually compise motor with lead screw or rack and pinion are slower and longer but can give even push force over long range. Probably too big.

8 cheap NiMH batteries contain 43200J, so it's just a question of making the energy do the useful work.
Something like this would work for the actuator:

6 pounds seems high, but that's based on all the pressurized cans of paint I've come into contact with.
RE: 12V Push Mechanism
I would go with a lead screw approach, since the force can be defined by the lead pitch and motor speed

Several companies make miniature air cylinders and valves. The best known is probably Clippard (www.clippard.com). Call a customer service rep there. They'll help you figure it all out. And you can get 12V air compressors several places. The most common use is as backups for auto tire inflation.

I have a lot of research to do from your suggestions.
I appreciate all your kind and thoughtful help.
RE: 12V Push Mechanism
Advantage would be to avoid mechanical issues of matching actuation to plunger valve movement. Solenoid valve can use power of pressurised paint to seal valve and low power coil can be used.
Ploblems would be getting valve suitable paint medium. Needs a bit of research
