What is hydraulic shaper mechanism?
The Hydraulic shaper uses the oil under high pressure. The end of the piston rod is connected to the ram. The high-pressure oil first acts on one side of the piston and then on the other causing the piston to reciprocating and the motion is transmitted to the ram.
What is the mechanism of shaper machine?
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. This machine consists of a constant discharge oil pump, a cylinder , a valve chamber and a piston.
What is hydraulic type shaper?
Shaper is a type of machine which, using hydraulic power, provide linear relative motion between the workpiece and single-point cutting tool to a linear path. Under high pressure, oil is pumped into the piston-fitted operating cylinder. This machine gives the following advantages.
Which fluid is used in hydraulic shaper?
Hydraulic fluid It is usually petroleum oil with various additives.
Which mechanism is used in shaper machine Mcq?
Quick return mechanism is used in shaper machine – Manufacturing Processes – 2. Q.
Which quick return mechanism is used in shaper?
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.
Hydraulic shaper mechanism. In this type of shaper machine mechanism, the ram is moved forwards and backwards by a piston moving in cylindrical placed under the ram. The machine is consists of a constant discharge oil pump, a cylinder, a valve chamber and a piston. The Piston-rod is bolted to the ram body. As shown in the figure.
What is the specification of shaper machine?
The specification of shaper machine depends upon the following: The maximum length of stroke ram. Types of the drive (Crank, Gear and Hydraulic type) Power input of the machine
What is quick return mechanism in shaper machine?
Generally, the cutting stroke is carried out at slow speed and the idle stroke is carried at high speed with the help of quick return mechanism. In the shaper machine, there is another mechanism called Quick return Motion Mechanism. In the forward stroke, the Slider moves fast and removing the material from the workpiece.
What is the function of the Shaper mechanism in a ram?
The shaper mechanism is so designed that it moves the ram holding the tool at a comparatively slower speed during forward cutting stroke, whereas during the return stroke it allow the ram to move at a faster speed to reduce the idle return time. This mechanism is known as quick return mechanism.
