The present invention relates to a method for manufacturing a bent pipe, in particular to an automated intelligent manufacturing method for a bent pipe.

According to the general elbow manufacturing, the pipe is cut into a pipe of a predetermined length by a cutting machine, and then manually moved to the pipe bender. The pipe bending machine is used to bend the pipe into a elbow, and then the pipe is manually bent. Remove the elbow and move it to the inspection tool to inspect the angle, length and flatness of the elbow to ensure the quality of the elbow. However, this is not only inconsistent in operations, but also requires a lot of manpower and time, and has the disadvantages of high labor costs and low work efficiency.

In order to improve the above-mentioned deficiencies, some industry has created an invention patent of Announcement No. I364332 "Integration of straightening, cutting, conveying, and bending pipe processing systems", which arranges straightening units and delivery units in sequence along a conveying direction. , Cutting unit, conveying unit and pipe bender. After the pipe is straightened by the straightening unit, it is transported to the cutting unit by the conveying unit to cut the pipe, and then the pipe is transported to the bend by the conveying unit. The pipe machine performs pipe bending operations.

However, the above-mentioned processing system is only suitable for a large number of single-type bending pipe processing, and after processing, it is also necessary to manually move the bending pipe to the inspection tool for quality inspection, so the practicality is not good, and it still has inconsistent operations and labor costs.
