INSERTED WIPER DIE FOR HIGH-PRESSURE TUBE-BENDING AND METHOD OF USING SAME |
摘要 |
The present invention is a wiper die assembly that combines the performance of a solid-body wiper die with the economy of a inserted wiper die for high-pressure rotary-draw tube-bending. The key features of the present invention are: [1] A wiper insert attached to the wiper holder by a mechanical means that retains the bore of the insert as a smooth, uninterrupted working surface, and [2] radius face support shoe attached to the wiper holder that can be adjusted to support and stabilize the entire wiper assembly against the cavity of the bend die.
