ヤマナカゴーキン Company Overview

We solve the concerns of designers and developers, such as 'abandoning forging due to complex shapes' and 'long lead times due to numerous prototypes.' Yamanka Gokin, a leading company in mold design and CAE analysis, has launched a 'Forged Product Development Site' that consolidates case studies directly related to solving engineers' challenges. By combining 60 years of expertise with cutting-edge simulations, we strongly support your product development. <Highlighted Cases on the Site> No Cutting: Forging the serration part of bevel gears to achieve both process reduction and improved accuracy. Breaking Limits with Deep Hole Processing: Achieving deep hole forging with an L/D ratio of 10 times, exceeding processing limits. One-Shot Forming of Complex Shapes: Significantly reducing manufacturing costs by utilizing multi-axis compound presses. With optimal method proposals based on over 1,500 insights, we simultaneously achieve reduced development costs, lightweighting, and increased strength.

The advanced feature of the CAE software "DEFORM," known as "strongly coupled analysis," is a method that allows multiple physical phenomena to interfere in real-time. However, in practice, the key consideration is whether the accuracy gained justifies the increase in computation time. In this article, we conducted a comparative verification of strongly coupled and weakly coupled analyses using the forging of helical gears as a subject. We visualized the differences in analysis results from three perspectives: "load," "contact pressure," and "stress." For more details, please refer to the related links.

In optimizing the heat treatment process, it is impossible to separate the flow of gas from the changes in the quality of the workpiece. The CAE software "DEFORM" allows for seamless coupling of fluid analysis (CFD) and gas quenching analysis within the same software. [Key Points of This Case] - Visualization of Gas Behavior: Precisely understanding the velocity distribution and flow bias within the cooling tank. - Prediction of Quenching Quality: Analyzing the temperature and microstructural changes of each part of the helical gear over time according to the flow. - Identification of Cooling Irregularities: Quantifying the heat transfer rates for specific areas such as the tooth tip, tooth root, and inner diameter. DEFORM's unique strength in simulating "from fluid to quenching" in a continuous manner supports next-generation quality design. For more details, please refer to the related links.
