If the pipe cutter operator wants to stop working midway, he must first control the pipe cutter to return to the starting point of the program (or the origin of the steel plate), and then he can continue cutting the next time. It is obvious that if the pipe cutting machine suddenly fails during normal operation (such as power failure, servo system failure, control computer crash, etc.), the operator cannot return it to the starting point of the program (or the origin of the steel plate) because it has no power failure memory function. When the fault occurs, first remove the fault. After the cutting machine returns to normal, use the above method to make it zero, and then use the remembered coordinate value to find the starting point of the program (or the origin of the steel plate). In this way, the breakpoint continuous cutting can be realized smoothly until the whole steel plate is cut.
In production practice, we successfully solved this problem by manually setting the zero point for the pipe cutting machine. The problem that the pipe cutter returns to the starting point of the program (or the origin of the steel plate) after a failure occurs. No matter how many X and Y coordinates the cutter displays now, press the Z key to make them all return to zero, and this position is the zero set for the cutter manually. The CNC flame cutting machine then operates the cutting machine according to the position of the steel plate to set the starting point of the program (or the origin of the steel plate). After setting, remember the X and Y coordinate values at this time. This coordinate value is the relative position between the zero point of the cutting machine and the starting point of the program (or the origin of the steel plate). The specific operation method is as follows: first, operate the cutting machine to make the longitudinal sliding seat slowly contact the measuring rod, and compress the spring to make it deform properly. At this time, set the dial indicator head to "0"; Then use the same method to set the dial indicator head of another zero device to "0".

The export product structure of pipe benders has not improved significantly. The export of metal processing machine tools has shown a straight upward trend, and the growth of CNC metal processing machine tools has exceeded 66%. Among them, the export growth of CNC special processing machine tools, CNC lathes, CNC boring machines, CNC gantry milling machines and CNC forming bending machines exceeded the overall growth of CNC pipe benders.

The pipe bending machine production line can automatically complete the pipe molding work when the specific work procedures are complete, which brings more convenience to the pipe bending work, saves human resources in the work process, and reduces the risks in the operation process.
