YBW Series Warm Extrusion Production Line for CV Joint Components

The YBW Series Warm Extrusion Production Line is designed for high-force warm forming of automotive and industrial metal components. It combines servo-driven hydraulic technology, programmable process control and integrated safety systems to support stable, repeatable production.

The line is suitable for forming inner and outer CV joint components, housings, stainless steel parts and other forged metal products. Its forming capabilities cover forward extrusion, backward extrusion, combined extrusion and die forging, allowing manufacturers to configure the process according to component geometry and production requirements.

Standard Configuration

• Integrated main cylinder and rapid approach cylinder for faster press movement

• Separate hydraulic oil cooling system for continuous thermal management

• PLC-based control system with Human-Machine Interface (HMI)

• Infrared light curtain system for operator protection

• Two-hand control system for safer press operation

• Real-time monitoring of hydraulic pressure and oil temperature

• Automatic alarm and shutdown functions for abnormal operating conditions

Servo Control and Process Management

The YBW Series incorporates high-speed servo control technology to improve motion efficiency and reduce unnecessary energy consumption during the forming cycle.

Digital Forming Parameter Control
Pressure, slide stroke and other forming parameters can be digitally configured to achieve repeatable production conditions.

High-Speed Press Movement
Rapid approach and return speeds help reduce non-forming time and improve overall cycle efficiency.

Tooling Data Management
Process and mold parameters can be stored in the control system and recalled when the corresponding product or tooling is selected. This reduces setup time when switching between production programs.

Process Curve Monitoring
Motion curves can be displayed in real time through the HMI, allowing operators and process engineers to monitor machine behavior and identify opportunities for parameter adjustment.

Main Applications

The YBW Series is primarily intended for warm extrusion and forging operations involving automotive and industrial metal components.

Typical applications include:

• Inner CV joint components

• Outer CV joint components

• CV joint housings

• Stainless steel formed parts

• Automotive forged components

• Metal transmission components

• General industrial forgings

• Warm extrusion parts requiring controlled dimensional accuracy

The production line supports multiple forming methods, including:

• Forward extrusion

• Backward extrusion

• Combined extrusion

• Die forging

This process flexibility allows the same equipment platform to address different component structures and tooling configurations.

Technical Specifications

Forming Performance

The warm extrusion process provides a practical balance between forming force, dimensional control and surface quality.

Compared with conventional cold extrusion, warm forming can lower the force required for deformation and consequently help reduce stress and wear on forming dies. Compared with conventional hot forging, extrusion-based forming can provide improved dimensional accuracy and surface finish.

For suitable component designs, the process can produce near-net-shape parts, reducing the amount of secondary machining required after forming. The actual achievable accuracy, surface condition and machining allowance depend on material, part geometry, tooling design and process parameters.

Hydraulic and Cooling System

The hydraulic system is designed for high-force forming operations and provides a maximum working pressure of 25 MPa across the YBW Series.

An independent hydraulic oil cooling arrangement is provided to control oil temperature during operation. A continuous plate-type water cooler or industrial oil chiller can be selected as an optional cooling solution.

Maintaining suitable hydraulic oil temperature is important for stable machine operation, particularly when the press is used for extended production cycles.

Safety System

Operator protection is integrated into the press control architecture.

Infrared Light Curtain
The infrared light curtain detects access to the protected operating area and provides an additional safety barrier during machine operation.

Two-Hand Controls
Two-hand operation helps keep the operator's hands away from the forming area when the press is activated.

Pressure and Temperature Monitoring
The PLC continuously monitors key operating conditions, including hydraulic pressure and oil temperature.

Alarm and Automatic Shutdown
When monitored parameters reach abnormal conditions, the control system can trigger alarms and automatic shutdown functions to help prevent overload, overheating or potential equipment damage.

Production Changeover and Tooling Management

The PLC/HMI control platform supports storage of multiple mold and process data profiles. Operators can recall the required settings when changing between products, reducing repetitive manual parameter entry.

This function is particularly useful for manufacturers producing several CV joint sizes or different forged components on the same equipment platform.

The YBW Series is available in five nominal force configurations from 5000 kN to 12000 kN, corresponding to YBW-500T, YBW-630T, YBW-800T, YBW-1000T and YBW-1200T.

For specific production requirements, the effective working area, stroke and daylight opening can be configured according to tooling dimensions, component size and production volume.
