Spring Testing Machine


Spring Testing project is the one of the mechanical project. Which is very useful for the final year and all student from the Mechanical.. Here you can get the more information about this project that is Spring Testing Machine..

SPRING TESTING MACHINE



In spring working industry a wide range inspection machine are used. As the industry is large and growing industry different type of the machine are used for different opertions.
This project the spring rolling machine is very simple in operation by using microcontroller with digital display. This machine is used to testing the types of spring load test in different diameters and length of spring. This machine can be used in various fields. 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 example of spring, which can be seen in our every day lives. The metals generally used for spring rolling work include iron, copper, tin, aluminium, strainless and brass.

This project the "Spring Testing Machine" finds huge application in all spring manufacturing industry.

Working Principle


The microcontroller receives the signals from power supply unit; the transistor T1, T2, T3 and T4 is used to ON the each letter one by one with respect to the load appling to the spring.

The circuit drew the power from the rectified 12 volt supply. This 12 volt is regulated by 5volt with the help of 7805. The 12 MHz crystal oscillator is used in this circuit. This oscillator is used to decide the operating speed of the microcontroller.

Time=1/frequency
=1/(12*10^-6)
=0.08microsecond

Advantages


1.Low cost load testing machine.
2.The total memory requrirement for program and data is only 4 kilobytes.
3.Easy to change the program.
4.Power drawn the circuit is low.

Disadvantages


1.Additional cost is required.
