Tools Used in Pipe Bending Machines

These days, with the rapid development of technology, some machines are invented to facilitate the processes of some industry. Pipe bending machine is one of the machines. They are mainly used for structural, decorative purposes or as passageways. Nevertheless,according to different requiremnets, there are various techniques that are followed. As we all know,pipe and tube bending machines are mainly used in industries and are usually pneumatic powered, human powered, electric servomotor or hydraulic addicted or driven. Besides the machines and the processes,in the sturucture of the pipe bending machines,there are different types of tooling used. Now,let me have a discussion about some tooling used. Here are some detalis.

Bend die:

A bend die is the forming tool that is used to make the specific radius of the bend. This die has two pieces namely the insert and the bend radius. While the insert radius is used to clamp the tube to the bend, the bend radius is the one that forms the arc of the bend when the tube is drawn around the die.

Clamp Die:

The clamp dies works along with the bend die to make sure that the tube is clamped to the bend die. This die moves in and out to allow feeding of the tube.

Pressure die:

The pressure die is what is used to press the tube into the bend die and this is the tool that provides reaction force required for the bending moment. This die travels along with the tube as it is being formed. A boost cylinder is attached to the pressure die in order to prevent tube breakage and to assist the die through the bend.

Mandrel:

Mandrel is a linked ball or a steel rod that is placed in the tube as it goes through the bending process. The main purpose of a mandrel is to offer more support to the tube and to prevent wrinkling or breakage of the tube throughout the bending process. There are different types of mandrels available such as the plug mandrel – a rock-solid rod, which is used in case of normal bends, a form mandrel – constitutes of the solid rod with a curved end and is used in cases where support is needed, a ball mandrel with/without cable – used on precise and critical bends.

Wiper die:

The wiper die is used only in situations where using a mandrel alone is not enough to prevent wrinkling during the bending process. The wiper die actually works by wiping away wrinkles on the tube.

From the above, we can know some of the tools used in the tube bending processes and more detailed information about the tools. And this series machines have features of unique design, compact structure, good appearance and easy to operate. Even more, it is high level of automation and labor saving.More information:www.mhpipe.com
