evening all,
so ive got a potential job to produce little clips in reasonable quantity circa 20,000 pcs ongoing. Im waiting for an eye watering quote for a die set tooling to be produced. laser, turret punch etc is too expensive for this sort of work and i need a follow style progressive tool due to features
originally i planned to utilise my ironworker to do the job and change the footpedal out temporarily to run automatically but im worried with the high quantity im going to end up having issues as it was never designed for this sort of work and this is utilised on other jobs its fairly new baileigh 40t capacity not sure my concerns are right.
so I'm on the hunt for a press if i get the job. ive calculated i need approx 6/8tonne to punch this but i would like extra capacity for other jobs all ready lined up in the future. i havent got a massive budget and not looking for super high speed as this will be automatic so i can do something else whilst running. hoping for a part to be 1/2 seconds each tool is designed so every stroke is a part produced
Material will be on a coil and ill import a pneumatic feeder unit that i can set for length and these are triggered mechanically as the press comes down.
ive seen these hare presses and the longer stroke version as well.
I'm well aware these are old and i can get the rams etc reconditioned as needed.
What i wanted to know from the collective if anyone has run them what they are like?
if anyone could guess/knows a cycle time. from what ive seen they are usually mechanically triggered by pulling the guard down. although i have seen a progressive stamping line with several of these running automatically
Im thinking to have the guard permanently down (ive got some lightguards i can use for protection as well theres no employees involved in this business) and then make up a connection for the lever to an air cylinder that i can control via a selenoid or something? or there maybe a way to do this via the hydraulic circuit.
My other option is a mechanical style power press which ive seen utilised for this sort of work seem to be reasonably quick (circa 115 rpm) and theres a few available for reasonable price.
My main concern on these is mostly the age and condition of them! also the shear size of them (most are 40t capacity) used to have a small one at a place i worked at and wasnt very powerful but still a big lump and wasnt very reliable.
Thanks for any advice etc ive had to do a bit of research on this and learnt a lot about toolmaking in the process
