About Link drive Eccentric press LS 4 model
1. Drive and Control Systems
The LS 4 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.
