Title:
高温成形工具の自己補償型後退可能インサート
Document Type and Number:
Japanese Patent JP2014524355
Kind Code:
A
Abstract:
A forming tool apparatus is provided for forming an article having a negative draft angle that locks the formed article within the forming tool. An insert, which is disposed within a recess defined in a forming surface of the forming tool, has a surface that cooperates with the forming surface of the forming tool to shape a metal blank into a desired final shape. In particular, the surface of the insert is shaped to define the negative draft angle feature of the formed article. Subsequent to forming the article, a linear-drive mechanism is activated to withdraw the insert away from the formed article, and thereby unlock the formed article from the tool. The formed article is then extracted from the tool along an extraction direction that is other than parallel to the direction along which the insert is driven.
