Springback Cause Analysis System Using Measured Shape of Press-Formed Parts

Solves the riddle of springback in trial press forming! A next-generation press-forming support system that revolutionizes die shape modification!

Solution Point

Accurately identifies the causes of springback in actual press forming.
Reduces die tolerances and working time required to achieve successful results.
Shortens calculation time by automation of the analysis process.
Realizes dies with stable dimensional accuracy.

Features 01

Expected Problems

Aren't you having these kinds of problems in press forming?

• Product quality is unstable due to frequent occurrence of dimensional deviations caused by springback.

• Die shape tuning is extremely time-consuming and expensive, and reduces production efficiency.

• Have not established effective countermeasures because it isn't possible to identify the areas that cause springback.

Features 02

Technology highlight

• High-accuracy back-calculation of the bottom dead center (BDC) stress distribution using 3D shape measurement data after springback of formed parts (Fig. 1).

• Calculates the difference between the BDC stress distribution by elasto-plastic FEM analysis and the measurement-based stress distribution (Fig. 2).

• Identifies the areas of stress that cause springback by analyzing the differential stress distribution (Fig. 2).

• Stress can be effectively controlled by changing the part and die geometry at the specified areas.
