Bolt Cold Heading Coupled Die Stress Analysis

A DEFORM-2D simulation coupled the plastic deformation solution for a bolt with the elastic deflection solution of its cold header tooling.


Product: DEFORM-2D

Summary:

The cold heading processes utilized to produce small fasteners are some of the most commonly simulated applications in the DEFORM system. The leading multinational fastener manufacturers rely on the system when developing and optimizing progressions.

DEFORM-2D has demonstrated coupled die stress analysis since 1990. Coupled analyses model dies as elastic bodies throughout a metal forming operation. This technique is particularly useful in identifying high tooling stresses that only mid-stroke. Computer analysis allows such stress states, which may lead to short tool life, to be predicted before ever running physical parts.
