The document describes the design of an automatic pneumatic internal pipe scrap removing machine. It uses compressed air to power a pneumatic cylinder with a round file attached, which is used to remove scraps from the inside of pipes. The machine aims to increase efficiency and accuracy by reducing human involvement in the scrap removal process. It works by using compressed air to power the forward and backward stroke of the cylinder and file, which removes pipe scraps automatically. This provides a faster, more consistent method of internal pipe scrap removal compared to manual methods.

1. AUTOMATIC PNEUMATIC INTERNAL PIPE SCRAP
REMOVING MACHINE

2. ABSTRACT
• Today, automation has intensely entered in industrial
manufacturing process measure to get identical and precision of
every product by reducing the human inclusion.
• Most of the industries use pipelines for their goods exchange from
one place to another. Within 1 or 2 years, inside the pipelines
scraps are formed.
• Scraps are simply saying as the wastage of the metal including
scales, rust etc. It decreases the efficiency of the pipes and also
contaminates the fluids pass through it. It is hard to remove only
using man power and it is also slower process.

3. • Automatic pipe scrap removing machine is one of such machine use for large scale production
and target at reducing the human involvement in order to increase the efficiency and exactness of
the product.
• In a pneumatic system, the functioning fluid is a gas (mostly air) which is compressed above
atmospheric pressure to give pressure energy to the particles. This stored pressure potential is
converted to a reasonable mechanical work in a proper controlled arrangement using control valves
and actuators.
• So we made a cylinder block consists of piston arrangement and using the pressurized gas to
remove the scraps in the internal pipes by using round files fitted at the end of the external stroke.

4. INTRODUCTION
Now a days products are required to be produced on mass scale which, ultimately reduce the
production cost. For that purpose different techniques are developed. Today, automation has
powerfully entered in the industrial manufacturing process in order to get identical and accuracy of
each product by reducing the human involvement. Automatic production is carried out for mass
production which aims at reducing the manufacturing cost of a product. Automatic pipe cutting
machine is one of such machine use for mass production and aim at reducing the human
involvement in order to increase the productivity and accuracy of the product. Pneumatic systems
form the most primitive and distinct class of mechanical control engineering. They are classified
under the term 'Fluid Power Control', which describes any process or device that converts,
transmits, distributes or controls power through the use of pressurized gas or liquid. In a pneumatic
system, the working fluid is a gas (mostly air) which is compressed above atmospheric pressure to
impart pressure energy to the molecules. This stored pressure potential is converted to a suitable
mechanical work in an appropriate controlled sequence using control valves and actuators.
Pneumatic systems are well suited for the automation of a simple repetitive task. The working fluid
is abundant in nature and hence the running and maintenance cost of these systems are
exceptionally low

• Design & Fabrication of Automatic-Pneumatic Pipe Cutting Machine.
• Cutting machine is one of the principal machines in industry. There is continuous development of
sophisticated machines and modern techniques are implemented for economical manufacturing of
products. At the same time, care should be taken that there has been no compromise made with
quality and accuracy. In the age of automation, machine becomes an integral part of human being.
By the use of automation machine prove itself that it gives high production rate than manual
production rate. Today, automation has powerfully entered in the industrial manufacturing process
in order to get identical and accuracy of each product by reducing the human involvement.
Automatic pipe cutting machine is one of such machine use for mass production and aim at
reducing the human involvement in order to increase the productivity and accuracy of the product.
New machines and techniques are being developed continuously to manufacture various products
at cheaper rates and high quality. Automatic pneumatic pipe cutting machine uses a pneumatic
circuit for cutting of PVC pipes which, ultimately reduces the total time required for the complete
cutting operation and increases the production rate

• Electromagnetic Scrap Collecting Machine with Vacuum System
• The intention of this mechanical engineering project is to fabricate a scrap
collecting machine. Since complete automation is very complex and even research
facilities haven’t come up with one, you better design one that is operated via a
remote control. The automatic scrap collecting machine is designed to remove
metal scraps from the work station to the disposal area with the help of Magnet
and IR sensor. The use of this automated vehicle system reduces human efforts
and the chances of hazard. The collecting work station consists of the work room,
conveyors and iron shattering machine. The big iron scraps from the work area is
collected by a conveyor and is brought to a iron shattering machine to reduce its
size. This shattered iron scraps are brought away from the machine to the rail
module through a conveyor for disposal

• DESIGN & DEVELOPMENT OF PNEUMATIC SHEARING MACHINE
• Today in the rapid competition of the industries to get the best
quality of the product in the minimum required time is the main
aim of industries. To get the best quality and maximum production
most advanced machines are used. But there is no facts that use nly
the advanced machines, to maintain their performance is real
requirement of the industries, also to give proper facilities to the
workers with good environmental condition and to reduce their
efforts is one of the objects to achieve the best quality and high

• Design and Manufacturing of Pneumatic Burr Removing Machine
• Many machines today are using of electrical, hydraulic and pneumatic component as a source of
system. So, to gain skills and knowledge on how to develop machine, this paper are recommend.
With the title of “Design and Manufacturing of Pneumatic Burr Removing Machine”, there are many
requirements to know such as function of pneumatic component the purpose of this paper is
making Burr removing machine for application of wheel clutch. The greatest advantage of
Pneumatic punches is their speed. Pneumatic punches are approximate 10 times faster than
hydraulic punches and they can perform many jobs faster and more efficiently. They can also be
stopped at any time by opening the valves to release the air. Pneumatic punches are extremely
flexible, that they can be placed in a factory in any required position, even upside down. The
objective of this paper is to manufacture a pneumatic punching machine which is necessary for
removing the burrs present in the holes of any casting product which saving the manufacturing lead
time in the process and also system is worker safety, By using this system the productivity is also
increase

9. WORKING PRINCIPLE
 The compressed air from the compressor reaches the solenoid valve. The solenoid valve changes the
direction of flow according to the signals from the timing device.
 The compressed air pass through the solenoid valve and it is admitted into the front end of the
cylinder block.
 The air pushes the piston for the round scrap file attached at the end of stroke. And also air from
the solenoid valve reaches the rear end of the cylinder block.
•
 The pressure remains the same but the area is less due to the presence of piston rod.
•

10.  This exerts greater pressure on the piston, pushing it at a faster rate thus
enabling faster return stroke.
 The stroke length of the piston can be changed by making suitable
adjustment in the timer. This pneumatic cylinder operates and controlled
by air.
 Forward and backward stroke movement of the round scrap file removing
pipe scraps effectively and also increases the flow rate of the pipes.
