Hydraulic Tryout Presses

hydraulic Tryout Presses Tryout as Success Factor Complex forming processes, new materials and the demand for the highest levels of economy and efficiency characterize the stamping plants of the automobile- and supplier industry of today. The continuous expansion of the number of models also increases the required number of die sets. To keep the start-up costs of new die sets as low as possible it is important to bring the dies up to speed for volume production quickly and efficiently. Schuler tryout systems are custom-tailored to meet this requirement. The equipment and the expertise of...

Short start-up times Tryout conditions close to for new dies actual production In the modern stamping plant, tryout Advanced tryout systems permit the presses are no longer an option but start-up of large dies at conditions essential components of a sequence close to actual production values.

The interplay between press, die, characteristics of the drawing systems material, and lubrication is so complicat- found on mechanical...

MULTIPLE APPLICATIONS Optimizing Uptimes Tryout presses close the gap between die manufacturing and part production. They simulate the production lines during die manufacturing or just before actual production in the stamping plant – whether as a simple die spotting press, flexible tryout press, or as a complete tryout center with various press types, moving bolsters, and die turnover devices.

Technical equipment Slide parallelism monitoring The control of parallelism between slide and bed is performed by means of a digital measuring system with read-out. The Schuler parallelism monitor works continuously during the entire slide stroke and protects press and die from off-center loading beyond permissible limits. The current parallelism deviation is displayed on the screen. The press is immediately shut down if the permissible deviation is exceeded. Infinitely adjustable slide locking Bolster cover Rotating Slide With this feature the slide can be For protection of the bed cushion...
