Applications for using a brake press to stamp text or emblems into a part 1

[bjlasota]

Looking to see if anyone has ever used a press brake and produced custom tools with a stamping die to place part numbers or emblems on a part? I'd like to stamp a 10 digit part number into thin sheet steel utilizing a 50, 120, or 300 ton press brake. I have a stamper made for this and stamping dies with a mirror image of the part number machined into them. But thinking of possibly saving a step by creating a custom tool that could install into my press brake as a first hit before forming the part.

Holders for letter stamping using brake presses are commercially available.

The tool exists but I think you would hydroolic press channel (Finnish youtube channel of things being tested to destruction in a press) the tool in presses of that range.

I figure a solid hammer stroke from a 3 lb hammer is about 5-10 tons.

Wilson makes tooling for stamping text using a press brake:

Thank you so far everyone!

@3DDave: I have found some, but I need to go beyond lettering. I need to put a custom symbol on there. I can likely make a custom tool for the holder though.

@TugboatEng: I'll probably end up making a custom version of these stamps per 10 digit part number. I need to stamp up to 600 parts per day.

@JohnRBaker: I have seen that and I will likely have to custom design something similar. This shows me that it has been used in applications on press brakes before though.

We had a supplier that made parts for us.
He had a very basic solenoid driven stamp attached to his brake.
The labeled parts with drawing numbers, or part number, or just descriptions.
His was manually triggered and his guys would usually label a part in two or three locations depending on size.
You could also do this with one of the pin stamping machines.
Then you could print whatever you wanted with no hard tooling.

Very interesting thread.
@bjlasota - what is the reason to stamp big quantities and not to go with engraving / marking for example?

Similar to John's experience, Wilson also makes holders for turret punches. We stamped part numbers all the time using these.

@hendersdc And it is also possible to get the special units to use punch press tools on press brake as well, even standard Thick Turret
