Shaping Machine: Application f Quick-Return-Crank-Slider Mechanism:

What made a shaping machine a reality!!

In the last two posts we have discussed about the Quick-Return mechanism a and the Slider-Crank mechanism. Now if we combine both these mechanisms we get a hybrid of the two to make the shaping machine work. The diagrams of the Quick-Return and the Crank-Slider mechanisms are being reposted for your quick reference:





When the above two mechanisms are combined in such a way that an 


  • An "inversion of the quick-return-mechanism" is used by means of a Rocker arrangement, having a slider inserted in its slot, for manipulating the rotation of the crank.
  • The Crank-Slider mechanism is the same i.e. without inversion 
The combination of the two makes the system workable and is used in  most of the Shaping Machines.
