| titleOfInvention | Horizontally-oriented, opposed motion, balanced-at-impact punch press |
| abstract | A punch press has first and second opposed tools mounted on first and second members, and these members are movable toward opposite sides of material to be formed between the tools. These motion members are electromagnetically driven with rapid acceleration toward each other for impacting fast-moving first and second tools simultaneously against opposite sides of the material to be formed. The two opposed motion members with their respective electromagnetic drives are arranged for the momentum of the first tool with its associated moving parts at the instant of impact to be substantially equal to the momentum of the second tool with its associated moving parts so that equal and opposite impulses resulting from the respective momentums substantially cancel each other out. As a result of this opposed motion with momentums-balanced-at-impact, very little energy or work is wastefully lost into a platform or other support for the punch press, and only an insignificant or very modest amount of mechanical shock and vibrations are induced into the platform or other support. Thus, little noise is transmitted into the environment via the platform or other support. The material is fed into the region between the first and second tools by a feed mechanism which is also movable in either direction. Various arrangements are disclosed for appropriately positioning the feed plate between the opposed tools and for controlling their respective electromagnetic drives for achieving substantially simultaneous impact of the tools with substantially equal momentums against opposite sides of the material to be formed between the tools. |
