Factors affecting productivity of a Tandem Line:

■ Part weight and size
■ Drawing depth
■ Distance between presses
■ Automation performance
■ Type of operation mode
■ Press drive
■ Press speed

Features & Benefits

Eccentric Drive

• Eccentric Gear Execution
• Welded Frame (According to size)
• Fixed Pin
• Integrated Temperature Monitoring System (Option)
• High Stiffness
• Low Number of Parts
• High Reliability
• High Con-rod Length / Crank Ratio

Link Drive

• High Stiffness
• Lower Working Speed
• In Line Configuration at BDC
• High productivity

The kinematics, carried out by link-drive system, permits to work at low and constant speeds during the drawing phase and at higher speeds during the idle stroke of the slide, as well as during the back-up motion of the slide up to the T.D.C. These speed variations are obtained with low value accelerations and continuous movement without any vibration.
