Key Machine Features

Prestressed Steel Wire Wound Structure

The steel wire wound design incorporates prestressed construction technology to support the machine's high-force operating requirements. Combined with the hydraulic system, this structure is intended for demanding industrial forming applications.

High-Pressure Hydraulic System

The hydraulic system provides the force required for extrusion, forging, sizing, and other pressing operations. Maximum working pressure varies by model, allowing buyers to compare equipment specifications against their process requirements.

CNC and PLC-Based Control

The control system combines CNC technology with PLC control and an HMI interface. This configuration supports coordinated machine operation and enables operators to manage the forming process through the machine's control interface.

Independent Oil Cooling

An independent hydraulic oil cooling system helps manage oil temperature during machine operation. This configuration supports hydraulic system operation under demanding production conditions.

Integrated Operator Protection

An infrared light curtain safety system is included in the standard configuration to help protect operators around the machine's working area. Additional safety functions should be confirmed against the final machine configuration.

Frequently Asked Questions

Q1: What benefits can hot extrusion offer for manufacturing constant velocity (CV) joints?

Hot extrusion can combine advantages associated with cold extrusion and hot forging. Compared with cold extrusion, it can reduce forming force requirements and help limit die wear. Compared with conventional hot forging, it can provide improved dimensional accuracy and surface finish. Depending on the component design and process conditions, near-net-shape forming can also reduce the amount of subsequent machining required.

Q2: How can servo-drive technology improve the efficiency of ball cage production lines?

Servo-drive systems can support rapid approach and return movements, helping shorten machine cycle times. Precise digital control of force and stroke can also improve process repeatability and help reduce scrap. The actual speed and productivity depend on the machine model, tooling, workpiece, and configured production process.

Q3: Can YBW presses be configured for different CV joint dimensions and production requirements?

Yes. The YBW series is specified with a nominal force range of 500 to 1,200 tons. Customization can include bolster dimensions, effective working area, stroke, and daylight opening according to tooling requirements and production needs. The PLC system can also support multiple tooling data profiles for product changeovers, subject to the selected control configuration.

Q4: What safety measures are available for high-pressure pressing operations?

The YBGR series includes an infrared light curtain safety protection system. Two-hand controls and additional monitoring functions, such as pressure and oil-temperature alarms or automatic shutdown, should be confirmed according to the specific machine configuration. Buyers should verify the complete safety system and applicable compliance requirements before installation and commissioning.

Q5: What after-sales services are available for overseas buyers?

Available support may include remote technical assistance, video-guided installation, on-site commissioning by engineers when required, spare parts documentation, and maintenance manuals. The scope of service, response arrangements, commissioning availability, and spare parts supply should be agreed upon with the manufacturer before purchase.

Product Selection and Customization

When selecting a YBGR Series Steel Wire Wound Hydraulic Press, buyers should evaluate the required forming force, material characteristics, workpiece dimensions, tooling arrangement, stroke, daylight opening, and production cycle requirements.

For application-specific configurations, confirm the required working table dimensions, pressing speed, hydraulic operating conditions, control functions, and safety provisions with the manufacturer before finalizing the order.
