RAM stroke, also known as stroke length or travel, is a fundamental measurement in the operation of a hydraulic press.
Understanding RAM Stroke in Hydraulic Presses
Based on industry definitions, the slider/ ram stroke, also known simply as "stroke length" or "travel, is a critical parameter in a hydraulic press that determines the maximum distance the hydraulic ram or piston can move vertically or horizontally during a pressing operation. This movement is essential for the press to perform its intended function, such as forming, stamping, or bending materials.
The stroke essentially defines the working range of the press's moving component (the ram or piston). It dictates how far the upper platen (connected to the ram) can travel towards the lower platen or bolster.
Key Role of RAM Stroke
The significance of the ram stroke lies in its direct impact on the capabilities of a hydraulic press:
- Maximum Part Height/Depth: The stroke length determines the maximum height or depth of the part that can be processed by the press in a single operation. For instance, if you need to form a deep drawn part, you will require a press with a sufficient ram stroke to accommodate the necessary travel.
- Tooling Compatibility: The stroke must be compatible with the tooling (dies) being used. The dies need to fit within the available daylight (the distance between the platens when the ram is at its highest point) and the stroke must be long enough to complete the pressing action through the die.
- Operation Efficiency: While not directly impacting speed, a longer stroke might require more time per cycle simply due to the distance the ram must travel. However, the stroke setting is often adjusted to the minimum required distance for a specific job to optimize cycle time.
In summary, the ram stroke is a defining characteristic of a hydraulic press, setting the limit for the ram's travel and thereby influencing the types and sizes of operations the press can perform.
