A Stewart platform is a type of parallel manipulator that has six prismatic actuators, commonly hydraulic jacks or electric linear actuators, attached in pairs to three positions on the platform's baseplate, crossing over to three mounting points on a top plate.
Then the pressure is released and punch retracted, hydraulic chamber lifted, and the process is complete. Among these techniques hydraulic bulge testing allows for an increased work hardening of sheet material by distinctive stretching operations and provides better shape accuracy for complex parts. Hence, by selecting proper material and the ...
Heidelberger Druckmaschinen AG (German pronunciation: [ˈhaɪdl̩ˌbɛʁɡɐ ˈdʁʊkmaˌʃiːnən ʔaːˈɡeː] ⓘ), sometimes referred to as Heidelberg or Heideldruck for short, is a German precision mechanical engineering company with registered offices in Heidelberg (Baden-Württemberg) and headquarters in nearby Wiesloch-Walldorf (Baden-Württemberg).

Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present.
Plate length: Depending on the scale of the system, total plate lengths can vary, however, the plate length should allow for the plates to rise 125 mm above the top water level, with 1.5 m of space left below the plates at the bottom of the clarifier for collection of sludge. [7] Most plates have a length of 1–2 m. [14]
A press brake is a special type of machine press that bends sheet metal into shape. A good example of the type of work a press brake can do is the back-plate of a computer case. Other examples include brackets, frame pieces and electronic enclosures. Some press brakes have CNC controls and can form parts with accuracy to a fraction of a ...
The sides of the plates are sealed by seam welding, other than the connecting ports. Finally, the gap between the thin metal sheets is pressurized by a hydraulic fluid causing a plastic forming of the plates, which eventually leads to their characteristic wavy surface.

[1] [4] [5] [6] Seventeen presses were originally planned with an expected cost of $389 million, but the project was scaled back to 10 presses in 1953. [7] Air Force Lieutenant General Kenneth B. Wolfe was the primary advocate for the Heavy Press Program. Alexander Zeitlin was another prominent figure of the program.
