Study of PLC Based Automatic Pipe Bending Machine

Electrical Engineering

Now a day in industries especially in automobile and other industries the automatic plate bending machines are widely used. Earlier the bending machines were operated manually. So the output of machine was very less. PLC based hydraulic bending machine operated manually or automatically. This machine used to bending the pipes at different angles. PLC based hydraulic bending machine in which PLC program are saved and it can be change as per customer requirements. In this machine manual operation can be done by using HMI (Human Machine Interface). PLC programmed are saved and easily changes the degree and doing the automatic process. This machine is used for long life and having more accuracy by using encoder. Because the movement of ram was done manually by rotating the screw. Now the technique of bending operation of the component is changed. Once the plate is loaded the operator should not only use once push button to start the machine. But he has operated two push buttons so that both the hands of the operator are engaged. This arrangement is made in order to avoid injuries to operators. The main aim of this project is to have the complete know how of pneumatic devices, sensors etc. by which the manually operated press or any machine can be converted into a semi or fully automatic unit. In this project the bending machine is a semi-automatic bending machine, in which the loading and unloading of the component is done manually and the bending of the plate is done automatically.
