Pre-forming line


The pre-forming line AR-D is a flexible forging line for volume distribution of long forging parts. The design of the line allows the production of a variety of different work-pieces without time-consuming tool-changes. It consists of the forming machine and two manipulators driven by servo motors.

The forming unit is a press with horizontal operation and two rams moving towards each other which perform a sinusoidal motion and are driven hydraulically.

As a special feature the ram movement is not realised via valve control. Thus the hydraulic system works without any pulsation and with extremely high efficiency. A combination of electric servo motors and hydraulic pumps (servo pumps) allows the dynamic adjustment of the ram stroke position so that parts with a large variety of contours can be produced.

Due to its technical concept the line can be seen as an alternative to radial forging lines, open-die forging lines and traditional stretching lines.

Special features:

  • Low tool costs
  • Universal use of forming tools
  • High energy efficiency
  • Fast stroke sequence - 200/min
  • Fewer intermediate heating cycles necessary due to quick operation
  • Fewer operations and less time for tool-change
  • Suitable for large forging parts even for small batches

Capacities: 10 - 10,000 KN
