Objective
In order to meet future demands on robust processes and on properties of final components more advanced process control in the sheet forming process is necessary. In fact, this is the only way to increase the use of advanced sheet materials as high strength steels, tailored blanks, light weight alloys etc. to the whole car body.
This in turn, is a prerequisite for meeting the well known higher demands on lighter and safer cars in future.
The blank holder force (BHF) is one of the most important process variables in controlling the sheet forming process for a given tool design. Today, the far most common procedure is to apply a constant BHF during the stroke. It is however, well known that advanced in process control of BHF can provide a more robust forming process, less sensitive to variations in the process.
The overall objective for the project is to introduce in process control of the blank holder force in the press shops on a large scale in order to increase productivity, decrease process sensitivity to variations in material and press parameters, and to enhance product quality.
The specific industrial objectives are:
To develop new BHF systems based on intelligent gas springs devoted to in process control of BHF in the industrial environment and to provide two complex dies aiming at demonstrating forming of typical geometries for vehicle components (front fender type and engine cover type).
To increase the sheet material yield stress level from 180 to 220 MPa for a front fender type component and to avoid reinforcements through utilization of tailored blanks for a component resembling an engine cover.
To implement closed loop control in a commercially available FE code to be used to define optimal BHFtrajectories for complex dies. To provide a computerized system devoted to a systematic
optimization of future dies by systematizing previous experience. The proposed approach to meet these objectives is to develop a systematic method to find the best BHFsolution for each die by using FE simulations in combination with experience and laboratory data collected in a computerized system. The systematic method is built and demonstrated on experiments and computations o two near industrial complex dies and a series of laboratory dies. The new BHF systems are targeted towards the two complex dies designed and constructed within the project.
