When it comes to welded pipe machines, everyone is familiar with them. However, with the changes in the market, the requirements for welded pipe machines are becoming increasingly diverse, especially when producing large-diameter thick walled welded pipes. The requirements for welded pipe machines and welding pipe molds are even higher. At this time, it is necessary to design universal racks. Today, we will focus on the application of universal racks in the quick change mode of welded pipe machines.

The specific application of the universal rack in the quick change method of the welding pipe machine is that the welding pipe machine does not need to replace the mold, and only needs to adjust the position of the welding pipe mold to achieve the production of different sizes of welded pipes. However, it must be emphasized that the complete set of non changing molds is only applicable to the production of square or rectangular pipes, and other types of pipes require mold replacement. The concept of quick change is mainly to directly adjust the specifications of welded pipes without changing the mold.

The structure of the quick change universal frame of the welded pipe machine is similar to that of the conventional welded pipe machine frame in the past, except that inner and outer vertical rollers are added between the upper and lower rollers. The overall workmanship and cost are similar to those of the old-fashioned welded pipe machine, but the cost of the welded pipe mold needs to be saved a lot. For square and rectangular pipes, only one-time investment is needed, and there is almost no cost investment in the future. In comparison, it is still much more affordable.

The universal rack is widely used in the production of square and rectangular pipes by welding machines, and its quick change method has been adopted by mainstream enterprises in the market.
