Mechanical vs Hydraulic vs Servo Presses

  1. 1. STAMTEC, INC. • 931-393-5050 4160 Hillsboro Hwy • Manchester, TN 37355 www.stamtec.com Mechanical vs. Hydraulic vs. Servo Presses
  2. 2. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com WHICH PRESS IS RIGHT FOR YOU? • The traditional mechanical press can achieve the highest production speeds... • The hydraulic press offers versatility... The answer is … it depends. There are many variables that can affect your decision, but the following rules generally apply: • The mechanical servo press offers versatility and higher production speeds... Mechanical vs. Hydraulic vs. Servo Presses
  3. 3. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com TRADITIONAL MECHANICAL PRESS OVERVIEW A mechanical press can achieve the greatest production speeds, especially for relatively flat parts with simpler, shallower forming requirements. These parts are typically processed from coil stock through a progressive or transfer die. Many automotive, appliance, and hardware parts fall into this category. Mechanical vs. Hydraulic vs. Servo Presses
  4. 4. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com TRADITIONAL MECHANICAL PRESS CHARACTERISTICS • fixed stroke length (although variable stroke length presses are available from some press manufacturers) • special slide motions (i.e. link motions) are available, specific to a particular press Mechanical presses traditionally have the following characteristics: • variable slide velocity, although slide velocity profile within a single cycle of the press is fixed Mechanical vs. Hydraulic vs. Servo Presses • working energy is dependent on flywheel mass and speed
  5. 5. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com TRADITIONAL MECHANICAL PRESS CHARACTERISTICS • full press capacity near bottom dead center of stroke • simplicity of set up and operation These characteristics also include: • in general, the highest stroking speeds Mechanical vs. Hydraulic vs. Servo Presses • high accuracy and repeatability • relatively low initial cost
  6. 6. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com HYDRAULIC PRESS OVERVIEW The hydraulic press does not generally achieve the high cycling speeds of a similar-sized mechanical press, but it does offer greater versatility with its variable stroke length, die space, and pressure. Mechanical vs. Hydraulic vs. Servo Presses
  7. 7. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com HYDRAULIC PRESS OVERVIEW This press is often the best choice when producing parts with deep, complex forms that require a lot of material flow and are not dependent on production speed. presses. Mechanical vs. Hydraulic vs. Servo Presses Parts such as tanks, cylinders, and bowl shapes, as well as parts that require a “dwell” at the bottom of the stroke (including plastics), are often run on hydraulic presses.
  8. 8. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com TYPICAL HYDRAULIC PRESS CHARACTERISTICS • variable stroke length • slide motion and position control throughout the range of the stroke length Hydraulic presses have a number of characteristics, such as: • variable slide velocity, even within a single cycle of the press (typically configured as fast approach, slow press, fast return) Mechanical vs. Hydraulic vs. Servo Presses • full working energy at any speed
  9. 9. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com TYPICAL HYDRAULIC PRESS CHARACTERISTICS • full press capacity at any point in the stroke • adjustability of all the previously listed characteristics Other characteristics include: • in general, slower than a mechanical or servo press Mechanical vs. Hydraulic vs. Servo Presses • in general, lower accuracy and repeatability than a mechanical or servo press • relatively low initial cost
  10. 10. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com MECHANICAL SERVO PRESS OVERVIEW The mechanical servo press offers much of the versatility of the hydraulic press, at production speeds often approaching traditional mechanical presses. The stroke, slide motion, slide position Mechanical vs. Hydraulic vs. Servo Presses and speed are programmable, allowing different combinations that can work with a wide variety of dies, part types, and production speeds.
  11. 11. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com MECHANICAL SERVO PRESS CHARACTERISTICS • variable stroke profiles • precise slide motion and position control throughout the range of the stroke length Characteristics of a mechanical servo press (where the flywheel, clutch & brake are replaced by high-capacity motors) include: • variable, precise slide velocity control, even within a single cycle of the press stroke Mechanical vs. Hydraulic vs. Servo Presses • full working energy at any speed • programmability of all the above
  12. 12. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com MECHANICAL SERVO PRESS CHARACTERISTICS • full press capacity near bottom dead center of stroke • in general, greater cycle speeds than a hydraulic press, in many cases approaching the speeds of a traditional mechanical press Other characteristics of these presses include: • high accuracy and repeatability Mechanical vs. Hydraulic vs. Servo Presses • relatively high initial cost
  13. 13. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com SERVO PRESS DRIVE TECHNOLOGIES There are currently two servo press drive technologies available. One is link-assisted. The link-assisted type of drive system is a cost-effective solution which utilizes standard, “off-the-shelf” A.C. servo motors. A link or toggle mechanism coupled with the motors creates mechanical ratios which allow for standard motor sizes from proven motor and control suppliers. No proprietary motors or motor controllers are required. Mechanical vs. Hydraulic vs. Servo Presses
  14. 14. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com SERVO PRESS DRIVE TECHNOLOGIES The other is a direct drive system, which employs proprietary, high-torque, low-rpm motors especially designed for press applications. These motors replace the standard motor, flywheel, and clutch/brake in an otherwise traditional crankshaft type of mechanical press. In either type of servo press, proprietary press controls specifically designed for the servo press achieve a wide variety of stroke and slide movement profiles, while supplying full working energy even at low speeds. Mechanical vs. Hydraulic vs. Servo Presses
  15. 15. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com SERVO PRESS DRIVE TECHNOLOGIES Using either type of technology, unique profiles can be created by the user. Preprogrammed profiles can include: Mechanical vs. Hydraulic vs. Servo Presses • cycle • deep drawing • swing • general forming • multi-pass • perforation/blanking • simulation of link motion • warm forming • compound pressing & forging
  16. 16. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com SUMMARY With full working energy at any speed and the ability to dwell anywhere in the stroke, servo presses are taking a big bite out of the drawn and formed parts pie. However, servos are still mechanical presses at heart, and therefore achieve full tonnage capacity near the bottom of the stroke. So in many cases hydraulic presses, with full tonnage and energy throughout the entire stroke, still have the advantage. Mechanical vs. Hydraulic vs. Servo Presses
  17. 17. STAMTEC, INC. • 931-393-5050 • 4160 Hillsboro Hwy • Manchester, TN 37355 • www.stamtec.com SUMMARY Mechanical presses are still the fastest, but they lack flexibility. Hydraulic machines allow more versatility in drawing and forming of complex parts but they’re slow. A servo press has many of the best characteristics of both. Mechanical vs. Hydraulic vs. Servo Presses
