Mechanical punching machine

  The mechanical punching machine is the machine that most used in the sheet metal stamping processing. According to the slider drive mechanism, the mechanical punching machine can be divided into different types.

  The mechanical punching machine that uses the crankshaft mechanism is called the crankshaft mechanical punching machine. Most mechanical punching machine use this mechanism.

  The reason for using the crankshaft mechanism the most is that it is easy to manufacture, the position of the lower end of the stroke of the slider can be correctly determined, and the slider activity curve is basically suitable for all kinds of  processing.

  Crankless mechanical punching machine is also called eccentric gear mechanical punching machine.  Instead of crankshaft, the crankless mechanical punching machine is equipped with eccentric gear. The crankless mechanical punching machine structure is superior to the crankshaft structure in terms of shaft rigidity and lubrication, but the crankshaft mechanical punching machine price  is better.

  Knuckle mechanical punching machine has the feathers that the speed of the slider  becomes extremely slow (compared to crankshaft mechanical punching machine) near bottom dead center. It is suitable for compression processing. Therefore, this type of mechanical punching machine is often used as a mechanical punching machine for cold forging.

  Friction mechanical punching machine is most suitable for forging operation, and can also be used for bending, forming, stretching, etc..  Because of its low price, it has been widely used.  It is gradually being eliminated because of its disadvantages such as low precision, slow production speed and high operator requirement.

  In addition to the mechanical punching machines mentioned above, there are also screw mechanical punching machine, rack mechanical punching machine,  link mechanical punching machine and cam mechanical punching machine.
