Bent tubes and pipes can be used for structural, decorative purposes or as passageways. There are various techniques which are adopted in line with the requirement and you will find different machines which facilitate these processes. Pipe and tube bending machines utilized in industries are often pneumatic powered, human powered, electric servomotor or hydraulic addicted or driven. In addition to the machines and also the processes, there are various kinds of tooling utilized in the bending machines. Given here is a brief on some tooling used.
A bend die may be the developing tool which is used to help make the specific radius from the bend. This die has two pieces namely the insert and also the bend radius. As the insert radius can be used to clamp the tube towards the bend, the curvature radius is the one which forms the arc from the bend once the tube is attracted round the die.
The clamp dies works combined with the bend die to make certain the tube is clamped towards the bend die. This die moves out and in to permit feeding from the tube.
Pressure die is accustomed to press the tube in to the bend die which is the tool that gives reaction pressure needed for that bending moment. This die travels combined with the tube because it is being created. A lift cylinder is connected to the pressure die to avoid tube breakage and also to profit the die with the bend.
Mandrel is really a linked ball or perhaps a steel fishing rod that’s put into the tube as the story goes with the bending process. The primary reason for a mandrel would be to offer more support towards the tube and also to prevent wrinkling or breakage from the tube through the bending process. There are various kinds of mandrels available like the plug mandrel – a rock-solid fishing rod, which is often used in situation of ordinary bends, an application mandrel – constitutes from the solid fishing rod having a curved finish and it is used in instances where support is required, a ball mandrel with/without cable – utilized on precise and demanding bends.
