ABSTRACT
Generally the cups and plate are made in plastics. The plastics are harmful and it has many disadvantages to us. By naturally we get leaves, Leafs by using this we can make cups. It is very cheap and it does not have any chemical effects. The Leaf cup is made by a pneumatic machine. The machine is operated by the pneumatic system. By using this we can produce cup at high production rate. By using different shape die we can produce different shape and size cups. The machine size is comfortable to suit any where.
The air enters to the flow control valve and gives pressure to the double acting cylinder. The direction is control by the direction 5/2 control valve. The movement of piston will be varied by adjusting the flow control valve. By adjusting the speed, the production rate will be varied.
The pneumatic Leaf cup making press is used to different shapes of cup in faster production rate. The principle of operation is the same as the conventional simple press. The difference is only in the type of drive and the type of fixtures used.
The following points reveals why we have to make use of this type of press
Pneumatic Leaf cup making press reduces the manual work.
This type of machine reduces working time.
By using this machine the bearings can be inserted in the various lengths of shat (up to 600mm).
In this Leaf cup making machine there is a double acting cylinder which is a pneumatic device a punch, die, screw rod, top plate, bottom plate, direction control valve, flow control valve, connectors and hoses. A compressor supplies high pressure air to the cylinder, whose flow is controlled by a flow control valve. The air passes through a direction control valve. This is used to actuate the piston and to specify its direction of movement. The piston is connected to a ram.
At the end of the ram punch is fastened. The die in the ram can be replaced. The piston, ram and punch are the moving parts in this machine. The die is fixed on the base of the machine by screw rods. The height of the base can be adjusted by rotating the screw rod. The whole unit is fixed on the column. When the air flows through the flow control valve, its volume is restricted to the specified amount. Then the direction control valves control the part of cylinder which it should occupy.
When it occupies part A of the cylinder, it moves the ram downwards along with the punch. The punch, punches the Leaf kept over the die. The Leaf will be wet. To recover the wetness and make the shape stable a heating coil is placed in the die. Next, direction control valves are actuated which makes the air to flow in part B of cylinder. Due to air in part A is released to the atmosphere by a valve. This makes the punch to move upwards. The cup can be taken out and the next Leaf can be placed over the die for the next cycle.
The pneumatic arm is more efficient in the technical field.
Quick response is achieved
Simple in construction.
Easy to maintain and repair.
Cost of the unit is less.
No fire hazard problem due to over loading.
Comparatively the operation cost is less.
Continuous operation is possible without stopping.
It reduces the manual work.
It reduces the production time.
Occupies less floor space.
Less skilled operator is sufficient.
DISADVANTAGES
While working, the compressed air produces noise therefore a silencer may be used.
High torque can not be obtained.
Initial cost is high.
Cylinder stroke length is constant.
Need a separate compressor.
