Can Crusher Project - Download as Word Doc .doc /.docx), PDF File .pdf), Text File .txt) or To design the pneumatic part of a can crusher and to fabricate the. Design Constraints − As a part of your challenge your can crusher design must: • use a pneumatic cylinder to crush the cans via a mechanism of some type. of the can crusher machine in the market, the completion of the new model moton. Pneumatic system, which are used extensively in industry and factories are.
As a result the sit in the cushioning chamber is again compressed since it cannot escape but slowly according to the setting made on reverses.
The air freely enters the cylinder and the piston strokes in the other direction at full Force and velocity. Commonly known as DCV; this valve is used to control the direction of air flow in the pneumatic system.
The directional valve does this by changing the position of its internal movable parts. This valve was selected for speedy operation and to reduce the manual effort and also for the modification of the machine into automatic machine by means of using a solenoid valve. A solenoid is an electrical device that converts electrical energy into straight line motion and force.
These are also used to operate a mechanical operation which in turn operates the valve mechanism. Solenoid is one is which the plunger is pulled when the solenoid is energized. The name of the parts of the solenoid should be learned so that they can be recognized when called upon to make repairs, to do service work or to install them.
COIL The solenoid coil is made of copper wire.
The layers of wire are separated by insulating layer. The entire solenoid coil is covered with a varnish that is not affected by solvents, moisture, cutting oil or often fluids. They are designed for such Frequencies as 50Hz to 60Hz. Since it is made of laminated sheets, it is magnetized when the current passes through the coil. The magnetized coils attract the metal plunger to move. The frame has provisions for attaching the mounting. They are usually bolted or welded to the frame.
The frame has provisions for receivers, the plunger. The wear strips are mounted to the solenoid frame, and are made of materials such as metal or impregnated less Fiber. The plunger is made of steel laminations which are riveted together under high pressure, so that there will be no movement of the lamination with respect to one another.
At the top of the plunger a pin hole is placed for making a connection to some device. The solenoid plunger is moved by a magnetic force in one direction and is usually returned by spring action. Solenoid operated valves are usually provided with cover either the solenoid or the entire valve.
This protects the solenoid from dirt and other foreign matter, and protects the actuator. In many applications it is necessary to use explosion proof solenoids. The working principle is as follows. This solenoid cutoff valve is controlled by the electronic control unit. In our project separate solenoid valve is used for flow direction of vice cylinder. It is used to flow the air from compressor to the single acting cylinder. The flow control can be achieved by varying the area of flow through which the air in passing.
When area is increased, more quantity of air will be sent to actuator as a result its speed will increase. If the quantity of air entering into the actuator is reduced, the speed of the actuator is reduced. Depending upon the method of controlling they are classified as 1. Pressure relief valve 2.
Pressure reducing valve 3. Connectors: In our system there are two type of connectors used. One is the Hose connector and the other is the reducer.
Hose connectors normally comprise an adopt hose nipple and cap 12 nut. These types of connectors are made up of brass or aluminum or hardened pneumatic steel.
So the air Pressure adjusted in the regulator is indicated in the pressure Gauge, is the line pressure of the air taken to the cylinder. Double acting pneumatic cylinder 2. Solenoid vale 3. Flow control valve 4. Connectors 5.
Synopsis On Pneumatic based can crusher
Hoses 6. Pneumatic driller 7.
Control unit 4. This pneumatic cylinder is powered by compressed air. Hand liver is used to control the pneumatic cylinder movement. By using this hand liver we can operate the pneumatic cylinder front and back, this movement is used for cane crushing operation.
This compressed air is given to the pneumatic cylinder through hand liver.
This hand liver will give the front and back movement to the pneumatic cylinder based on that movement. In this machine inlet and outlet is provided for cane movement. Used cane is dropped to the machine through inlet, then it crushed by pneumatic cylinder. The crushed can will come out from the machine through outlet way. The various requirements to be satisfied Can be weight, surface finish, rigidity, ability to withstand environmental attack from chemicals, service life, reliability etc.
The following four types of principle properties of materials decisively affect their selection a.
Physical b. Mechanical c.
AUTOMATIC PNEUMATIC CAN CRUSHER
From manufacturing point of view d. Chemical The various physical properties concerned are melting point, thermal Conductivity, specific heat, coefficient of thermal expansion, specific gravity, electrical conductivity, magnetic purposes etc.
The various Mechanical properties Concerned are strength in tensile, Compressive shear, bending, torsional and buckling load, fatigue resistance, impact resistance, eleastic limit, endurance limit, and modulus of elasticity, hardness, wear resistance and sliding properties. For example, it would never be desirable to go casting of a less number of components which can be fabricated much more economically by welding or hand forging the steel.
COST: As in any other problem, in selection of material the cost of material plays an important part and should not be ignored. Some times factors like scrap utilization, appearance, and non-maintenance of the designed part are involved in the selection of proper materials.
Thus with the help of this design we can fabricate an automatic can crusher machine to simply reduce the volume of cans as well as to reduce the human fatigue. Also the automatic operation can be possible using the mechanical power transmission operated by electric motor or electric actuator etc. This solely will reduce the volume of the cans or bottles to reduce the transportation cost by reducing its volume.
Ramkrushna S. More, Sunil J.
It can be placed everywhere, in the park, houses. To design the pneumatic part of a can crusher and to fabricate the pneumatic part of the system is the step to learn pneumatic engineering.
Whenever the air enters in the solenoid valve by the usage of hand lever the air allows to move forward by which the piston in the cylinder also moves forward. They have two ports to allow air in, one for out stroke and one for in stroke.
Applications These valves are used to control the speed of piston in a pneumatic cylinder. These are otherwise termed as nippers. Features Brass body and sintered bronze silencer elements Button, conical, silencer cum flow control with lock nut , silencer cum flow control with spring types. Good flow and silencing characteristics. Can be cleaned by kerosene and soap water. Pipe diameter is 5mts.
It is a PVC pipe. These pipes carry air from the compressor to cylinder by the means of solenoid valve and the other particles. These pipes are strong enough to carry in the system.
Base plates These are the plates which are used to give support to the cylinder as well as the cylinder is made to be a support and the base plates are there by giving a rigid supports to the cylinder. Punch Punch is the main object which is to crush the tin.They cannot attain pressure necessary for pneumatic control application unless built in multistage designs and are seldom encountered in pneumatic service. Also the transport of empty cans become difficult.
Pneumatic systems exhibit spongy characteristics due to compressibility of air. Design data for machine elementsby B.
Single acting cylinders equipped with one inlet for the operating air pressure, can be production in several fundamentally different designs. More, Sunil J. These process are about using material selection and make the product base on the design and by followed the deign dimension. When the pneumatic system is being adopted for the first time, however it wills indeed the necessary to deal with the question of compressed air supply.
The air freely enters the cylinder and the piston strokes in the other direction at full Force and velocity. A mechanical tin can crusher is basically one of the most aid able machines.
