Why Friction and Rack and Pinion Presses Are Being Eliminated

  Why Friction and Rack and Pinion Presses Are Being Eliminated
Punching machines are divided according to different driving force
   Slider drive can be divided into mechanical and hydraulic two kinds, so the punch press according to its use of different driving force is divided into:
(1) Mechanical power press (Mechanical Power Press)
  (2) Hydraulic press (Hydraulic Press)
Classification according to the slide movement
According to the slider movement mode classification of single-action, double-action, triple-action punch presses
   Classification according to the slider drive mechanism

(1)Crank Press
The press using crankshaft mechanism is called crank press, this type of press is practical for punching, bending, stretching, hot forging, warm forging, cold forging and almost all other press processing.
    (2) Crankless press (Crankless Press)
Crankless Press is also known as Eccentric Gear Press. When the stroke is longer, Eccentric Gear Press is more favorable, and when the stroke of the special-purpose machine for punching and cutting is shorter, Crankless Press is better. Therefore, small-sized machines and high-speed punching and cutting presses are also in the field of Crankless Press.
   (3)Knuckle Press
Knuckle presses use an elbow joint mechanism on the slide drive, and are called knuckle presses.

    (4)Friction Press
A press that uses a friction drive and a screw mechanism on the rail drive is called a friction press.
    (5)Screw Press
A press that uses a screw mechanism on the slide drive is called a screw press (or screw press).
   (6) Rack Press
 The rack and pinion mechanism used in the ram drive mechanism is called a rack press.
   (7) Link Press
A press that uses various linkage mechanisms on the slide drive mechanism is called a link press.
   (8) Cam type press (Cam Press)
A press that uses a cam mechanism on the slide drive mechanism is called a cam press.
