AutoForm Forming R12 – Feasibility Evaluation and Verification of the Press Forming Process

Introduction to the application and optimization of springback suppression shapes on wall surfaces.

This article introduces a case study that systematically addresses springback reduction by combining AutoForm-Sigma with shape modification functions, focusing on ultra-high-strength structural members with a hat cross-section. In the first half of this article, we discuss the background and methods of the initiative, as well as the processing steps, including the initial case study on imparting and optimizing springback suppression shapes on wall surfaces. *For more detailed information, please refer to the related links.

Introduction to changing the bending angle in the intermediate processing stage and adding a stepped shape to the upper surface of the product.

This article introduces a case study that systematically addresses springback reduction by combining AF-Sigma with shape modification functions, focusing on ultra-high tensile structural members with hat cross-sections. In the latter part of this article, we discuss changes in bending angles during intermediate processing and the addition of step shapes to the upper surface of the product. Finally, we will briefly verify the feasibility of the anticipated reduction in springback amounts. *For more detailed information, please refer to the related links.

We will introduce the evaluation results considering advanced friction models using TriboForm.

In the simulation study conducted at high tension, where issues are often observed, we will introduce a case that focused particularly on "friction" and worked on improving accuracy. With the goal of enhancing accuracy in the process (drawing die) and reducing lead time, we conducted calculations using AutoForm with two different friction conditions and compared the results with actual panel dimensions. In simulations using constant friction, phenomena that were excessively represented were confirmed to show behavior changes closer to actual panels by using the TriboForm model. This led to a reduction in lead time due to fewer modifications needed in die manufacturing. 【Key Points in Evaluation】 ■ Setting thresholds based on an understanding of the impact of friction (tribology) on quality ■ Establishing a feasible schedule aligned with the trial dates for evaluation ■ FV settings for AutoForm simulation (FV settings: parameter settings suitable for accuracy evaluation) ■ In-depth technical discussions on friction issues and sharing of concerns *For detailed information on the case, please refer to the related links.

Demonstrated excellent accuracy, speed, and consistency in a benchmark study predicting springback at the NIMISHEET2022 international conference.

The international conference "NUMISHEET 2022" on sheet metal forming simulation was held in Toronto, Ontario, Canada from July 10 to July 14, 2022. AutoForm participated in a benchmark study to predict springback using a panel with a twist die provided by the Auto/Steel Partnership (A/SP). This further demonstrated that the software can rapidly, accurately, and consistently simulate the entire press forming process. *For more details, please refer to the PDF document or feel free to contact us.*

Optimize press forming simulation to quickly correct product and die face development through springback analysis in the early stages.

By correcting the springback prediction adjustment, which is usually performed in the final stage of press forming simulation, at an earlier stage, it becomes possible to carry out the process more easily and cost-effectively after mold processing. 【Contents】 - Simulation applying more accurate material information - Mesh and control parameters effective for measuring springback - Simulation of parts that replicate the production plan - Construction of a safe "green" simulation - Notes on setting up springback analysis and measurement *For more details, please refer to the PDF document or feel free to contact us.

Volvo Car Corporation has adopted TriboForm for the door inner of the new Volvo XC90 to achieve its goals.

**Impact of Introducing TriboForm** By improving the prediction accuracy of strain, flow, and springback, we achieve "shortened development time," "reduced development costs," and "increased ROI (return on investment)."

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.
