PNEMATICS SHEET CUTTING MACHINE

ABSTRACT The sheet metal cutting process is a main part of the all industries. Normally the sheet metal cutting machine is manually hand operated one for medium and small scale industries. Automation in the modern world is inevitable. Any automatic machine aimed at the economical use of man, machine, and material worth the most. The sheet metal cutting machine works with the help of pneumatic double acting cylinder. The piston is connected to the moving cutting bled. It is used to cut the small size of the sheet metal. The machine is portable in size, so easy transportable

The compressed air from the compressor is used as the force medium for this operation. There are pneumatic double acting cylinders, hand operated lever valve and MS cutting bled are used. The arm from the compressor enters to the flow control valve. The controlled air from the flow control valve enters to the hand lever valve. The function of solenoid valves all of air correct time interval. The 5/2 & 1/4′′ hand lever valve is used. In one position air enters to the cylinder and pushes the piston so that the cutting stroke is obtained. The next position air enters to the other side of cylinder and pusses the piston return back, so that the releasing stroke is obtained.

INRODUCTION Automation in the modern world is inevitable. Any automatic machine aimed at the economical use of man, machine, and material worth the most. In our project is solenoid valve and control timing unit is used for automation. The sheet metal cutting machine works with the help of pneumatic double acting cylinder. The piston is connected to the moving cutting tool. It is used to cut the small size of sheet metal. The machine is portable in size, so easy transportable. The sheet metal cutting process is a main part of the all industries. Normally the sheet metal cutting machine is manually hand operated one for medium and small scale industries. In our project is “ PNEMATICS SHEET CUTTING MACHINE”.

BASIC PRINCIPAL

WORKING PRINCIPLE � � The compressed air from the compressor is used as the force medium for this operation. There are pneumatic double acting cylinders, hand operated lever valve and MS cutting bled are used. The arm from the compressor enters to the floe control Valve. The controlled air from the flow control valve enters to the hand lever valve. The 5/2 & 1/4′′ hand lever valve is used. In one position air enter to the cylinder and pusses the piston, so that the cutting stroke is obtained.

PNEUMATICS � � � Pneumatics is that branch of technology, which deals with the study and application of use of pressurized air to affect mechanical motion. “Pneumos” means “Air” and “Tics” means “Technology”. The compressed air is used as the working medium, normally at a pressure of 6 -8 bars(also can be extended up to 15 bar) and a maximum force up to 50 KN can be obtained. Pneumatics is used extensively in industry as well as in many everyday applications. It has many distinct advantages in terms of energy consumption, cost and safety. Pneumatic power is used in industry, where factory machines are commonly plumbed for compressed air (other compressed inert gases can also be used). Pneumatics also has applications in dentistry, construction, mining, and other areas.

SHEARED EDGE • Shearing – Separating material into two parts • Blanking – Removing material to use for parts • Conventional blanking • Fine blanking • Punching – Removing material as scrap • Piercing • Slotting • Perforating • Notching • Nibbling • Lancing • Slitting • Parting • Cutoff • Trimming • Shaving • Dinking

APPLICATIONS Ø Ø Ø This machine is very useful for small scale industries This machine is used to cut the roller sheet metal All Industrial Application hat the releasing stroke is obtained.

ADVANTAGES Ø Ø Ø Ø Ø The pneumatic 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 when compared to other machine No fire hazard problem due to over loading Comparatively the operation cost is less The operation of cutting is faster because the medium used to operate is air Continuous operation is possible without stopping

DISADVANTAGES Ø Ø Ø While working, the compressed air produces noise therefore a silencer may be used. High torque cannot be obtained Load carrying capacity of this unit is not very high.
