YB62 Series Warm Extrusion Forming Press for Housing Components

The YB62 Series Warm Extrusion Forming Press is a high-capacity hydraulic forming solution developed for precision warm extrusion and die forging applications. With models ranging from 1000 to 3000 tons, the series is designed for demanding production of automotive and industrial components where forming force, dimensional consistency, process control, and production efficiency are critical.

The press combines a high-speed hydraulic system, servo drive technology, digital process control, and integrated safety functions to support stable forming operations across different material and tooling requirements.

Product Applications

The YB62 Series is designed for warm extrusion and forming of:

• Automotive housing components

• Constant velocity (CV) joint components

• Long shaft components

• Stainless steel parts

• Copper components

• Aluminum components

• Other precision warm-extruded parts

Supported forming processes include:

• Forward extrusion

• Backward extrusion

• Forward and backward combined extrusion

• Die forging

• Other customized warm forming processes

The combination of high forming force and controlled extrusion parameters makes the YB62 Series suitable for applications where near-net-shape forming is preferred to reduce subsequent machining operations.

Main Machine Configuration

Integrated Main Cylinder & Rapid Approach Cylinder
The main hydraulic cylinder is integrated with a rapid approach cylinder to achieve efficient movement during the non-forming stage while maintaining the required forming force during the working stroke.

Independent Hydraulic Oil Cooling
A dedicated oil cooling system helps control hydraulic oil temperature during continuous operation. The cooling configuration can use a continuous plate-type water cooler or an industrial oil chiller as an optional solution.

PLC + HMI Control
The PLC-based control architecture provides centralized management of machine movement and forming parameters. The Human-Machine Interface allows operators to monitor operating conditions and adjust production settings.

Infrared Light Curtain Protection
An infrared light curtain safety system provides protection around the operating area. When the protected zone is interrupted, the safety system can respond according to the programmed control logic.

Servo Drive and Digital Process Control

The YB62 Series uses high-speed servo control technology to improve hydraulic system efficiency and machine response.

Key control functions include:

• Digital setting of pressure and forming force

• Stroke and position control

• Adjustable approach, pressing, and return speeds

• Storage of mold and process parameters

• Quick recall of saved production recipes

• Real-time process motion curve display

• Process monitoring and parameter adjustment through the HMI

The ability to save tooling and process data is particularly useful for manufacturers producing multiple part specifications. Previously established process parameters can be recalled when changing production models, reducing setup time and improving repeatability.

Warm Extrusion Forming Performance

Warm extrusion operates between conventional cold extrusion and hot forging conditions. Compared with cold extrusion, the elevated forming temperature can reduce the force required for material deformation and help lower the mechanical load imposed on the tooling.

Compared with conventional hot forging, controlled warm forming can provide better dimensional control and surface quality. Depending on the component design and process parameters, this can produce parts closer to their final geometry and reduce the amount of secondary machining required.

For CV joint and similar automotive components, this forming approach can help manufacturers achieve efficient material utilization while maintaining consistent component geometry.

FAQ

Q1. Why use warm extrusion for CV joint and similar automotive components?

Warm extrusion provides a compromise between cold extrusion and hot forging. The forming temperature can reduce the force required for deformation compared with cold extrusion, which can help reduce die loading and wear. At the same time, the process can provide better dimensional accuracy and surface quality than conventional hot forging. Depending on the component geometry, the resulting part can approach its final shape and reduce subsequent machining requirements.

Q2. How does servo control affect forming productivity?

The servo system supports rapid approach and return movements, with high-speed movement available according to the machine configuration. Digital control of forming force and stroke also helps maintain consistent process conditions. Together, these functions can shorten cycle time, improve repeatability, and reduce production variation in continuous manufacturing.

Q3. Can the press be adapted to different CV joint sizes and tooling configurations?

Yes. The YB62 Series can be configured according to specific tooling and production requirements. Depending on the project, working table dimensions, stroke, daylight opening, and other machine parameters can be considered during configuration. The PLC control system also supports storage of multiple tooling and process data profiles, making product changeovers more convenient.

Q4. What safety functions are provided for high-pressure forming operations?

The machine incorporates infrared light curtains and two-hand controls for operator protection. The PLC system can also monitor hydraulic pressure and oil temperature during operation. When abnormal conditions are detected, the corresponding alarm and protective shutdown functions can be activated according to the machine control configuration.

Q5. What support is available for overseas installations?

Overseas customers can receive remote technical assistance, video-based installation guidance, and commissioning support. When an on-site service is required, professional engineers can be arranged according to project requirements. Spare parts information and maintenance documentation are also provided to support routine maintenance and minimize production downtime.
