DESGIN AND FABRICATION OF SPRING ROLLING MACHINE
INTRODUCTION

.A Spring is a device that changes its shape in response to an external force,
.Returning to its original shape when the force is removed.
.The energy expended in deforming the spring is stored in it and can be recovered when the spring returns to its original shape .
.The amount of deformation is directly proportional to force exerted.
COMPONENTS
.SPUR GEAR
.SHAFT
.WIRE BUNDLE
.TENSION PLATES
.CUTTER
.HOLLOW CYLINDER BOX
.SPUR GEAR:
A spur gear is a gear whose teeth are perpendicular to the face of the gear.
.SHAFT:
It is used to transmit the motion.
.BUNDLE:
It is used to give the steel wire continously to the shaft.
.TENSION PLATE:
It is used to give the grip to the steel wire.
.CUTTER:
It is used to cut the wire.
.HOLLOW CYLINDER BOX:
It is used to get the different diameter of springs.
TYPES OF SPRINGS:
*COMPRESSION SPRING
*TENSION SPRING
*TORSION SPRING
*DISC SPRING
*CONICAL SPRING
*HELICAL SPRING
*SPIRAL SPRING
*FLAT SPRING
*ARM SPRING
*EXTENSION SPRING
COMPRESSION SPRING:
High durability,tensile strength and resistivity to adverse condition has also made the springs ideal for industrial applications.
TENSION SPRING:
Tension spring ensure high durability, tensile strength and resistivity to tensioning to tensioning forces or pulling forces
TORSION SPRING:
Endurance forces such as twist, rotation, lateral angular has made the Torsion Spring ideal for various industrial applications.
CONICAL SPRING:
Conical compression springs ensures high durability, tensile strength and resistivity to corrosion
HELICAL SPRING:
Helical Extension Spring ensure high durability, tensile strength and resistivity to corrosion.
SPIRAL SPRING:
Spiral Spring is manufactured using High grade stainless steel, PH., Bronze and copper that ensures high durability, tensile strength and resistivity to rust
FLAT SPRING:
High durability, tensile strength and resistant to corrosion has made the Flat Coil Spring ideal for various applications in industries like agricultural tools, automobile, etc.
ARM SPRING:
Lower Tension Arm springs due to its efficacy in applications in automobile, furniture, hardware and other areas.
EXTENSION SPRING:
The Conical Extension Springs offered by us highly durable, robust in structure and resistant to pulling force
WORKING PRINCIPLE
*By using the handle, rotate the shaft , then the motion will be transmitted from the shaft to driven gear.
*Driven gear transmitting the motion to the driving gear ,so that the shaft which, attached with the driving gear also rotated.
*The wire bundle which is used to supply the wire to the hollow cylinder box through the tension plates.
*Tension plates are used to give the grip to the steel wires by adjusting the nuts fixed at that top. So that the spring will be produced due to the rotation of handle ,
*Cut the spring by using the cutter to the required length.

APPLICATION
*ENGINE VALVE
*BUFFER
*RAILWAY BOGIE SUSPENSION
*PANTOGRAPH
*AUTOMOBILE SUSPENSION
ADVANTAGES
*Low cost
*Construction is simple
*By using single wire we can get different diameters of spring
*Compact
