The function of the straightening head of the pipe welding machine is to straighten the pipe on line. So it needs to install several welding pipe moulds. How many combination modes are better to use?

The welding pipe mouldfor pipe straightening head of pipe welding machine shall be determined according to the pipe type. Generally, the pipe welding machine for producing round pipe can be equipped with a straightening head to meet the requirements. The installed welding pipe mould is also carried out in two groups. Some of them also use four groups. For my own, I suggest two sets of modes for installation, because from the perspective of production, The more the quantity, the larger the tolerance, the more difficult it is to adjust. The production of two groups is also simple and easy to adjust. This is a positive effect. If it is the production of square pipe, then the pipe welding machine shall be equipped with two sets of straightening heads. Each straightening head shall be installed with four one group of welding pipe mould. This is to facilitate the shaping of pipe from 4 faces. Some adopt the combination of two sets of dies, which is not so easy for adjustment.

Therefore, it is reasonable to say how many welding pipe mould is used for straightening head of pipe welding machine and how to choose the combination, which mode to choose, according to the type of pipe produced, and different pipe materials adopt different combination mode.
