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.

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.*

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create 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! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four ways: left, center, right, with 4 spots and 12 spots settings. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor modes with a single model. 【Recommended for such places!】 ☑ Entrances facing busy corridors ☑ Counters or signs near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.
