The expansion process requires the continuity of several actions, which is very complicated compared to other attachments.
All steps require the transportation of pipes, side transfer, turning and uniform heating, clamping of pipes, expansion production and other working processes, in which the expansion is carried out in a closed forming chamber, using high-pressure forming, and the expansion is completed. Completely use cooling circulating water for water cooling.
The entire process is executed through the cylinder, hydraulic cylinder or chain drive, the limit switch is controlled by the travel switch or photoelectric tube, and the parameters such as time and temperature are set through the PLC or computer background program to ensure that the entire process is interoperable. Working together.
The working stroke of the pipe expansion machine control module is the axial offset of the expansion control module from the largest position to the smallest position, that is, the axial deflection caused by the expansion position to the retraction position. Shift, because the enlarged engine is composed of two types of control modules, the offsets during operation are different, so the working stroke of the control module is divided into the working stroke of the large control module and the working stroke of the small control module. arrange.
