The preforming 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 preforms without time-consuming tool-changes. It consists of the forming machine and two manipulators driven by servo motors.
The forming machine consists of two rams moving towards each other, which follow a sinusoidal movement and are driven hydraulically.
As a special feature, the ram movement is not realized 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 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 forming machines, open-die forging machines and traditional stretching lines.
Press force 10 – 10,000 kN
