About Link drive transfer press TL4 model
The TL4 Series Straight Four Point Multi-link Transfer Press, manufactured by YangLi Group Corporation Ltd., is a high-precision mechanical press designed for metal forming operations.
The press utilizes a six-link multi-link drive system that is optimized through specialized software to ensure efficient and reliable performance. It is equipped with a hydraulic overload protector for enhanced safety and an automatic oil lubrication system for easier maintenance.
The TL4 Series also offers various control options, including electronic and mechanical cam controls, with optional features such as air cushions, tonnage gauges, and anti-vibration pads.

Composition of Equipment
Frame Structure
The frame is composed of a welded crown, column, and bed, which are pre-tightened with tie rod bolts. This design ensures high intensity and rigidity, offering a solid foundation for the press's operations.
Drive System
The press is driven by a multi-link drive system with six links. This drive system is optimized using advanced software, ensuring efficient and reliable performance during operation. The high-strength gear components are made from alloy steel for enhanced durability and strength.
Slide Mechanism
The slide is supported by an eight-face rectangular guide, ensuring minimal lateral forces and smooth motion. The slide mechanism utilizes asynchronous drive technology to reduce wear and enhance operational accuracy.
Clutch and Brake
The press is equipped with a pneumatic friction clutch and a standard revolution brake for reliable control of the press cycle. An optional imported wet type clutch brake is available for more specialized applications.
Hydraulic System
The press includes a hydraulic overload protector, which ensures safe operation by preventing damage from excessive loads. The system automatically adjusts to protect the machine in case of overload conditions.
Working Principle

The TL4 Series operates with a multi-link drive system that optimizes the press's motion and performance.
The six-link configuration ensures smooth and precise movement of the slide, minimizing lateral forces.

The hydraulic overload protection system automatically adjusts the machine's operation when excessive force is detected, safeguarding both the press and the operator.
The automatic lubrication system ensures consistent oil flow to critical components, reducing wear and increasing the longevity of the press.
