The gaps are filled with compacted magnesium oxide sand, which has good insulation and thermal conductivity. Both ends of the tube are sealed with silicone. This metal-clad heating element can heat air, metal molds, and various liquids. Common types of electric heating elements include finned heating elements, Teflon heating elements, and quartz heating elements. Currently, most electric heating elements have a spiral or U-shaped curved structure to reduce space requirements and increase the heating area.

While this patented technology improves production efficiency, and the composite tube bending machine uses a robotic arm to transfer the heating tubes, resulting in a high degree of automation and requiring minimal human intervention, thus saving labor and reducing production costs, and utilizes bending die holes for heating tube positioning to ensure the consistency of the finished products and significantly improve the yield rate, it suffers from drawbacks such as the tubes being prone to shifting and rolling during bending, and the need for constant manual monitoring during the loading process, which is laborious.

[0038] Please see Figure 1 , Figure 2 , Figure 3This embodiment of an automatic bending device for U-shaped electric heating tubes includes a main body 1. Two fixing rods 2 are fixedly connected to the upper surface of the main body 1. One end of each fixing rod 2 is fixedly connected to a common feeding channel 3.

[0039] This embodiment of an automatic U-shaped electric heating tube bending device features a suction cup 17 and a soft pad 15. During operation, the suction cup 17 uses air pressure to adsorb the electric heating tube after the adsorption cylinder 22 is activated. The soft pad 15 and the pusher 9 protect and clamp the tube during bending, preventing deviation and unnecessary losses. It also effectively prevents the heating tube from shaking during bending, thus reducing metal fatigue. The feeding channel 3 and the shielding frame 4 allow for automatic material addition, automating the process. When the pusher 14 pushes the bent heating tube away, the toothed ring 7 and the rack 10 mesh, causing the feeding channel 3 and the shielding frame 4 to overlap, ensuring precise placement of the heating tube on the processing table 11. This prevents blockages during material addition and achieves a high degree of automation.

[0040] The working principle of the above embodiment is as follows: First, a sufficient number of heating tubes are placed into the feeding channel 3 at one end of the fixed rod 2. Then, as one heating tube is placed in the middle of the processing table 11, the infrared sensor of the adsorption cylinder 22 senses the material and is activated. The adsorption cylinder 22 then uses air pressure to adsorb the heating tube. The heating tube is then attached to the sponge block 16 to prevent damage to its surface during feeding. Then, the power module 21 activates the third electric telescopic rod 20, causing it to pull the processing table 11 backward. When the processing table 11 is pulled to its maximum distance, the second electric telescopic rod 18 is activated by the power module 21. The second electric telescopic rod 18 then pushes the two bending wheels 19, causing them to bend the heating element during rotation. During bending, the heating element adheres to one side of the soft leather pad 15 and presses the push head 14 at one end of the spring telescopic sleeve 13, compressing the spring telescopic sleeve 13 and protecting the heating element during bending to prevent it from shifting. Then, the push plate 9 of the first electric telescopic rod 8 pushes the bent heating element down, causing the rack 10 to engage the toothed ring 7. Afterward, as the nut sleeve 6 rotates, the threaded rod 5 pushes the shielding frame 4, causing the material in the feeding channel 3 to fall downward and roll to the middle of the processing table 11.
