Link Drive Eccentric Press LS4 Model

High-precision multi-link drive system with advanced control technology for superior performance and reliability

About Link Drive Eccentric Press LS4 Model

1. Drive and Control Systems

The LS4 model features a multi-link drive with options for six or eight links, designed using specialized software for precise performance. It combines an asynchronous drive to minimize lateral forces and a high-speed herringbone gear drive for smooth operation. The machine also offers dual control options—electronic cam and mechanical cam—providing flexibility and precision in operation.

2. Structural and Safety Enhancements

Key components are optimized using Finite Element Method (FEM) analysis for strength and durability. The slide is guided by an eight-sided rectangular guide for stability and accuracy. Safety features include a pneumatic friction clutch brake with an optional imported wet type clutch brake, as well as a hydraulic overload protector to ensure reliable operation.

3. Lubrication and Optional Features

The main lubrication is automated with oil, and an optional heating and cooling system helps maintain optimal operating temperatures. Additional options include an air cushion for improved surface finish and a quick die change device to enhance productivity.
