DAYEEGROUP and INOVANCE have reached a strategic cooperation agreement to jointly explore new opportunities in the hydraulic press industry.

Recently,Suzhou Inovance Technology Co., Ltd.，(INOVANCE) and Xuzhou Dayi Heavy Forging Technology Co., Ltd.,(DAYEEGROUP), the backbone enterprise of heavy forging equipment in China, jointly announced that the two sides formally signed a strategic cooperation agreement. In the future, the two sides will focus on forging press, a key industrial machine tool, and carry out in-depth cooperation in three major directions: electro-hydraulic servo energy-saving transformation, localization of intelligent control system and digital upgrading of equipment, aiming at jointly creating smarter, more efficient and more independent forging solutions and jointly promoting the forging process to be intelligent and green.

Intelligent Empowerment, Leading the Technological Transformation of Hydraulic Presses

The core of this collaboration is the deep integration of Inovance's cutting-edge automation and digitalization technologies with Dayi's mature hydraulic press platform. We will jointly develop a new generation of integrated and intelligent control systems, achieving more precise control of the hydraulic press's working process, more efficient energy management, and more stable operation. This signifies that our equipment will possess stronger adaptive capabilities, richer data interaction interfaces, and more convenient remote operation and maintenance functions, helping customers easily move towards intelligent manufacturing.

Dayi's core products: open-frame hydraulic presses and closed-frame hydraulic presses.

As a professional manufacturer in the field of hydraulic presses, DAYEEGROUP is always committed to providing customers with diverse and high-performance forming equipment. Our product line widely covers both open and closed main structural types to meet the diverse needs of different industries and processes:

1. Open Die Hydraulic Press

Open-die forging hydraulic presses are key equipment that utilizes powerful, controllable hydraulic power combined with simple flat dies to plastically form large metal workpieces (such as steel and titanium). They apply pressure to the heated workpiece using upper and lower flat dies, gradually forging it into large forgings such as shafts, rings, and discs. This process, with its flexible shape adaptability, superior grain structure control capabilities, and high forming accuracy, is widely used in aerospace, energy equipment, and heavy machinery industries. Modern open-die forging hydraulic presses are often equipped with automation systems and robotic manipulators, forming efficient and intelligent forging production lines.

Key Features and Functions：

lProcess Principle: Utilizes upper and lower flat dies to deform the heated metal locally or entirely. Unlike closed-die forging, which completely encloses the metal, it offers a higher degree of forming freedom.

lHydraulic Drive: Employs oil or water pressure systems to provide adjustable forging pressures of thousands of tons, ensuring stable power and precise control.

lProcess Versatility: Can perform various forging processes such as upsetting, bending, straightening, punching, and stretching, adapting to the forming needs of complex parts.

lTypical Applications: Manufacturing of critical parts such as large generator rotors, turbine discs, marine crankshafts, heavy machinery components, and aerospace structural parts.

lMaterial Range: Suitable for forging various metal materials including carbon steel, stainless steel, nickel-based alloys, titanium alloys, and aluminum alloys.

Core Advantages

lSuperior Performance: The continuous and complete metal flow lines during the forging process significantly improve the strength, fatigue resistance, and microstructural uniformity of the parts.

lHigh Forming Accuracy: Enables precise forming of complex-shaped parts with strict dimensional tolerance control, reducing subsequent machining allowances.

lHigh Production Efficiency: Equipped with advanced control systems, offering fast forging speeds and can be combined with automatic die changing and robotic operation to shorten production cycles.

lOutstanding Large-Scale Capability: Particularly suitable for manufacturing ultra-large and ultra-heavy parts that are difficult to produce with other processes, possessing strong specifications adaptability and production scalability.

2.Closed die hydraulic forging press

The closed die forging hydraulic press uses the pressurized fluid to exert huge and controllable force to shape the heated metal in the closed die cavity (die), so as to manufacture high-strength and high-precision parts and minimize material waste. This process has many advantages, such as excellent grain structure and reduced subsequent processing, so it is very suitable for the production of aerospace and automobile parts.

Core Features and Advantages

lHigh-Precision Forming: Capable of directly producing precisely sized forgings, usually requiring little to no subsequent machining, significantly reducing processing costs and time.

l Excellent Structural Strength: Forging aligns metal grains along the part's contour, optimizing the material's microstructure and greatly enhancing the part's mechanical strength and fatigue resistance.

l Flexible and Versatile Process: Can form parts with various complex geometric shapes, adapting to the diverse product needs of industries ranging from aerospace to general machinery.

lHigh Material Utilization: Compared to machining and other processes, it significantly reduces raw material waste, enabling more efficient and sustainable production.

Main Application Areas

lAerospace: Used to manufacture critical load-bearing components and engine parts with extremely high performance requirements.

lAutomotive Manufacturing: Production of precision forgings for important parts of engine systems, transmission systems, etc.

lIndustrial Equipment: Providing high-durability and high-reliability structural and functional components for heavy machinery, energy equipment, etc.

3.Axle extrusion hydraulic press

A bidirectional extrusion machine is an advanced hydraulic forming equipment used for producing symmetrical shaft-like parts (especially axles). Its core design features powerful, synchronized hydraulic rams positioned at both ends of the machine. During operation, a heated metal billet is placed in the central mold cavity, and the rams at both ends, under computer control, simultaneously apply pressure towards the center with extremely high synchronization accuracy. Under the uniform pressure from both ends, the metal material is extruded simultaneously from the pre-existing holes in the center of the mold to both sides, forming a complete axle blank with continuous fiber flow in a single operation.

Core features and advantages:

l Large tonnage and high rigidity: specially designed for hot extrusion/cold extrusion process of long shaft parts to ensure stable molding.

l Multi-action coordinated control: it can realize precise synchronization of complex actions such as extrusion, perforation and ejection.

l Efficient production beat: optimize for continuous production and improve batch manufacturing efficiency.

l Special mold and temperature control: heating system and mold cooling scheme supporting hot extrusion process.

Typical application scenarios:

Precision extrusion molding of long-axis parts such as automobile axle, truck axle, construction machinery axle, high-speed rail and special vehicle axle.

Xuzhou Dayi Heavy Forging Technology Co., Ltd. is one of the core enterprises in the field of heavy forging equipment in China, has long been focusing on the research and development, manufacture and service of fast forging hydraulic press, die forging hydraulic press and special forging equipment, and its products are widely used in aerospace, ship power, clean energy, heavy machinery and other key areas related to the national economy and people's livelihood.

At the critical stage of high-end and green manufacturing, the transformation of forging industry has gone beyond single technology upgrade, which tests the deep integration ability of control technology, equipment technology and data system. The cooperation between Huichuan and Xuzhou Dayi is an attempt to leap from "equipment manufacturing" to "equipment intelligent manufacturing", and also provides an intelligent transition path for forging industry.
