Which mechanism is used in shaper?
Hydraulic drive mechanism is one of the mechanism used in shaper machine. In this mechanism, the ram is moved forward and backward by a piston moving in a cylinder placed under the ram.
What are the quick return motion mechanisms make a list about it?
In quick return mechanism, a circular motion is converted into reciprocating motion just like crank and lever mechanism but it has return stroke time is different from forward stroke time. This mechanism is used in many machines. Some of them are shaper machines, slotter machines, screw press, mechanical actuator etc.
How quick return mechanism is is achieved in a geared shaper?
The shaper mechanism should be so designed that it can allow the ram to move at a slower speed during the forward cutting stroke. The cutting speed depending upon the type of material and machining condition whereas during the return idle return time. This mechanism is known as the quick return mechanism.
Why return stroke is faster than forward stroke?
When the cranks rotate, the slider will slide inside the slotter’s bar and oscillate the slanted bar. As the slotted bar oscillates, the ram will move forward and backward. This mechanism has a return stroke or, ideally, faster than a forward stroke.
Why return stroke is quicker than forward stroke?
The quick return mechanism is so designed that it moves the ram holding the tool at a comparatively slower speed during the forward cutting stroke, whereas during the return stroke it allows the ram to move at a faster speed to reduce the idle return time.
What are the types of quick return mechanism employed mostly in shaping machines is?
Quick return mechanism : Crank and slotted lever quick return motion mechanism. This quick return mechanism is mostly used in shaping machines, slotting machines and in rotary internal combustion engines. In this quick return mechanism, the link AC (i.e. link 3) forming the turning pair is fixed, as shown in fig.
