Production Parts Production Parts

High speed production for automotive body panels

Automotive body panels are formed on Komatsu ServoPress H*FTL line.

Press lines for automotive  body panels
High speed production for drawing/trimming/punching/cutting processes. Forming various types of automotive body panels

Productivity Productivity

increased productivity


*against robot tandem press line

1) Gain higher productivity by high speed feeder and obtaining ample transfer time due to phase difference operation of press machines ( PAT.P )
In addition to double arm feeder, single arm feeder with more flexible panel transfer has been developed and introduced in the market

2) Die interference check and most suitable motion generation by PLS ( press line simulator )

Ensure ample transfer time with phase difference operation
Slide motions of H*FTL press

Formability Formability

High formability by Servo press with servo die cushion

*against mechanical press with air die cushion

Servo die cushion with high-speed response of servo motors achieves high formability and shorter trial times by numerical control

Servo die cushion utilizing high-speed response of servo motor
Achieving high formability and shorter trial times

Formed parts Body side outer(deep drawing parts) Measurement items : For panels formed by mechanical press & servo press, sill parts measured and spring backs compared with CAD data. Measurement results Servo press could form almost exactly according to shape of die Mechanical press spring back quantity is approx. 1.7 times of servo press one
