ABSTRACT

In spring working industry a wide range of power and hand operated machines are used. As the industry is a large and growing industry different type of machines are used for different operations. Our project the spring rolling machine is very simple in operation by using spur gear arrangement which is coupled with motor. This machine produces round spring of different diameters and length. This machine can be used in various fields. This machine consist of two spur gear which is coupled with a motor and connecting the spur gear shaft with rolling main shaft. This machine is simple in construction and working principle.

INTRODUCTION

Spring rolling industry is a large and growing industry. There are many special purposes machines used in this industry to-day. The proper selection of the machines depends upon the type of the work under-taken by the particular industry. There are many examples of spring, which can be seen in our every day lives. The metals generally used for spring rolling work include iron, copper, tin, aluminium, stainless and brass.Our project the “SPRING ROLLING MACHINE” finds huge application in all spring rolling industry. Rolling is the process of bending metal wire to a curved form. The article in the shape of round is made by spring roller shaft. Rolling operation can be done on hand or power operated rolling machines. In forming round spring shapes a gradual curve is to be put in the metal rather than sharp bends. The gap between the springs can be regulated by proper arrangement.The lock nut is used to fixing the spring wire to the rolling shaft. The spring wire is supplied by a tare is called spring wire tare. This tare is fixed to the stand by two end bearings. The tare is rotated freely during the time of spring rolling operation. The single phase induction motor is coupled with the spur gear arrangement by pulleys. The motor is rotated by switch on the power supply of single phase. The spur gear is rotated due to the rotation of motor. The spur gear is coupled with the main shaft by bearing.

WORKING PRINCIPLE

The single phase supply is given to the induction motor, it will run. The motor pulley is coupled to the spur gear pulley with the help of belt. The spur gear arrangement is run according to the speed of the motor. Before switch on the induction motor, the spring wire is locked to the lock nut in the spring rolling shaft. The spring wire is supply by a spring wire tare. The tare is fixed to the frame stand by two end bearings, so that it will run freely according to the speed of the spring rolling shaft.The spring rolling shaft is rotated when the single phase induction motor switched ON. The spring wire is rolling in the rolling shaft due to the rotation of the spring rolling shaft. The length of the rolling spring is decided by the operator. The required length of the spring is rolled; the single phase induction motor is switched OFF. The spring is cut by the cutter, the next above procedure continue once again for the next spring operation.
