Hydraulic press lines

HYDRAULIC PRESS LINES From the blank to the finished part Hydraulic press line with Schuler blankloader and robot automation. Total press force: 89.000 kN (five presses). Hydraulic press lines permit the efficient and versatile series production of mediumsized and large parts. The press lines comprise four to six automated stand-alone presses depending on the required forming operations. Automation systems for blank loading, press interlinkage and finished part handling and stacking, designed specifically for the respective line, ensure reliable and economical series production. 2

TECHNICAL EQUIPMENT Ring valve technology Benefits at a glance The cycle times of hydraulic presses can be significantly reduced by means of ring • Short switching and pressure valve technology. Used in prefill valves release times it provides fast filling of the cylinders • Flow-optimized design during rapid closing. After the working • High closing and return stroke stroke, the pressure in the cylinder has to be released quickly so that the slide can speeds • Targeted pressure release, complete its return stroke. Unlike conventional prefill valves, the ring valve can especially for...

Dynamic force control To increase productivity, production 900 Time gain 800 presses can be equipped with dynamic 700 force control. The press has three 600 working cylinders. Part yield is increased 500 by means of the automated adaptation to 400 the required forming force and, therefore, to an increase in slide speed. During Conventional drive Dynamic force control 300 phase one of the operation, only the 200 center cylinder provides the necessary 100 force, tripling the working speed. In phase two, if the full nominal force is required, the press automatically cuts in the other slide...
