We have pleasure in introducing our new project “FABRICATION OF HYDRAULIC V-TYPE

ANGLE BENDING MACHINE”.

A work piece can be bent in multiple directions and angles. Common simple bends consist of forming elbows, which are bends that range from 2 to 90°, and V-bends, which are 180° bends.

INTRODUCTION

BENDING PROCESS BENDING PROCESS

Work piece bending as a process starts with loading a work piece into a work piece bender and clamping it into place between two dies, the clamping block and the forming die.

The work piece is also loosely held by two other dies, the wiper die and the pressure die.

HYDRAULICS SYSTEMHYDRAULICS SYSTEM

Pascal's law: states that for an incompressible fluid at rest, the difference in pressure is proportional to the difference in height and this difference remains the same whether or not the overall pressure of the fluid is changed by applying an external force.

hydraulic pump with a small swept volume that asks for a small torque, combined with a hydraulic motor with a large swept volume that gives a large torque. In such a way a transmission with a certain ratio can be built.

Most hydraulic drive systems make use of hydraulic cylinders. Here the same principle is used a small torque can be transmitted into a large force.

WORKING PRINCIPLEWORKING PRINCIPLE

When a bending force is applied to a work piece (work piece) under free bending conditions, the initial bending is elastic in character.

This is because the stresses that are developed in the opposite faces of the material are not sufficiently high to exceed the yield strength of the material.

The stresses developed on the inside of the bend tend to shorten the metal and are, therefore, compressive stresses.

The movement or strain which takes place in the work piece as a result of the initial bending force is elastic only and, upon removal of the force, the work piece springs back to its original shape.
