Cold cutting saw is an emerging online cutting technology in the welded pipe industry. The main feature is that it adopts the principle of cold milling. After cutting, the pipe end is flat and free of burrs. There is no need for secondary cutting for applications with high processing requirements. In addition, due to the adopted servo follow-up fixed-length tracking technology, the cutting length accuracy is higher than that of ordinary computer flying saws. In the production process, dust and noise pollution are significantly reduced.
The whole system adopts Siemens full digital motion control system Simotion and Profinet network combination, servo motor all through the network control, through 10 "touch screen input system parameters, system operating parameters are clear and accurate, and real-time record system alarm information. The base steel plate of the saw is welded and processed after tempering. The moving parts are all driven by linear linear guide rail and ball screw. It has its own lubrication system. The whole flying saw machine is stable and reliable, and the electric control system is advanced.

The automatic steel pipe packing and palletizing machine
The automatic steel pipe packing and palletizing machine is used to automatically complete the collection and stacking of welded pipe at the end of the welding pipe production line, to run smoothly automatically, to reduce the labor intensity, to improve the automation degree of the production line, and to effectively improve the production efficiency. At the same time, it can reduce the impact noise, remove the bumping injury, improve the product quality, reduce the production cost, and eliminate the hidden danger of safety.
