Where is Whitworth quick return mechanism used?

5] The Whitworth quick return mechanism is generally used in shaper machines & slotting machine in which forward stroke is slower for machining purposes & return stroke is faster as there is no machining process is to be done.

What is quick return mechanism used for?

A quick return mechanism is an apparatus that converts circular motion into reciprocating motion in presses and shaping machines, which are utilized to shape stocks of metal into flat surfaces. This mechanism is mostly used in shaping machines, slotting machines and in rotary internal combustion engines.

Which of the mechanism is example of quick return motion mechanism?

Explanation: Quick return motion mechanism is used in Shaper machine. The shaper 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 differences between crank and slotted lever mechanisms and a Whitworth quick return mechanism?

The difference between the crank and lever mechanism and the Whitworth mechanism is that in the Whitworth mechanism the return stroke is faster than the forward stroke while in the crank and lever mechanism the forward stroke is of the same speed as that of the return stroke. 1) Slotted Bar. 3) Crank – It will rotate.

Is quick return mechanism is responsible for Ram movement?

Explanation: Due to the rotation motion of the disc, the ram moves forward and backwards. During half rotation, the ram moves forward whereas during the other half rotation. The ram quickly returns. In a quick return mechanism, the forward reciprocating motion is faster rate than the backward stroke.

What is crank slotted mechanism?

The crank and slotted quick return mechanism converts rotatory motion into linear motion. It is extensively used in shaping and cutting machines and is particularly useful in cutting flat surfaces out of metal stock. The mechanism consists of an arm attached to a rotating disc that moves at a controlled uniform speed.

How are the Whitworth quick return mechanism and crank & slotted lever mechanism different from each other?

The difference between the crank and lever mechanism and the Whitworth mechanism is that in the Whitworth mechanism the return stroke is faster than the forward stroke while in the crank and lever mechanism the forward stroke is of the same speed as that of the return stroke. 1) Slotted Bar.
