hyperform input blank formation between first draw and restrike tool

Recommended Posts

Hello Sir,

(This question arises from the development of the draw surface)

If process has sequence as follows:

1. Blanking process

2. First Draw process

3. OD trimming process

4. Re-strike process ....as in one-step we get the flat blank from any draw/forming tool, as the same process can we get the blank input (blank with draw shape) for the re-strike tool from the first draw tool (i.e. input blank for re-strike based upon first draw operation)


Please share if any another process sequence / video explaining regarding the same.

Hello Vipin SIr,

Thank you for the reply but actually my problem is that, (please refer the above process sequence) I want to develop the 1st draw surface from which I will get minimum thinning and wrinkles in the final draw ( re-strike process). so as like one-step blank formation, likewise can we get the optimum shaped blank for the re-strike stage( 2nd draw stage)?

so that from this optimum shaped blank I will get the First Draw tool surface.
