[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model uses a feeding assembly to stably drop the heating tube into the receiving trough. The feeding assembly moves the heating tube to the double-hook bending assembly, which bends both ends of the heating tube. Then, the feeding assembly moves the heating tube to the arc bending assembly, which performs arc forming on the heating tube. The push rod moves the feeding plate forward to push the formed heating tube down onto the belt conveyor for transport. This achieves automated operation, and bending and arc forming are performed on the same machine without changing machines, saving time and effort, improving production efficiency, and solving the problem that most existing rice cooker heating tubes are bent multiple times through multiple processes, which is time-consuming, labor-intensive, and has low flexibility and processing efficiency.

[0016] (2) By setting a second cylinder at the upper end of the bending seat, the output of the second cylinder is used to fix the lower pressure seat. After the heating tube is inserted into the bending groove, the output end of the second cylinder drives the lower pressure seat to move down and press down the heating tube to prevent the heating tube from falling and improve stability.
