Method for hydraulically controlling a link-type press or a toggle press and link-type press or toggle press with a control system adapted for carrying out the method

摘要

The invention relates to a method for hydraulically controlling a link-type or a toggle press and a link-type or toggle press with a control system adapted for carrying out the method. An innovative feature is that in the operating region of the press ram (3), the speed of the driving piston rod (2) is increased at least once. The speed of the ram (3) is therefore kept relatively constant until the lower part is reached. IMAGE
