This invention proposes a long-life electric radiant tube heater, comprising an iron-chromium-nickel alloy heating wire, a ceramic body frame, a radiant tube sleeve, and heat dissipation fins. The iron-chromium-nickel alloy heating wire is threaded onto the ceramic body frame, and the iron-chromium-nickel alloy heating wire and the ceramic body form the electric heating core of the electric radiant tube. The radiant tube sleeve is fitted over the outside of the ceramic body frame, and the heat dissipation fins are fixed to the outer wall of the radiant tube sleeve to enhance heat dissipation. The long-life electric radiant tube heater proposed in this invention, by adding heat dissipation fins to the outside of the radiant tube sleeve, can improve heat dissipation efficiency, reduce the heat load on the material, and thus extend its service life.

This invention discloses an automated welding equipment for wheelchair manufacturing and forming, belonging to the field of wheelchair welding technology. It includes a mounting frame with a welding mechanism at its top. The welding mechanism includes a welding equipment body rotatably mounted in the middle of the mounting frame. A rotating wheel is fixedly mounted on the outer surface of the welding equipment body, and multiple telescopic welding pipes are arranged on the outer surface of the rotating wheel. A contact sensor is installed on the surface of the welding equipment body near the telescopic welding pipes. A limit mechanism is provided at the top of the mounting frame. This invention, by setting a rotatable rotating wheel and a circumferentially distributed array of telescopic welding pipes, combined with a gear meshing drive structure, can complete multi-point synchronous spot welding around the circumference of the wheelchair components. Simultaneously, a hydraulically driven moving plate enables automatic workpiece alignment. Combined with the sensing linkage between the contact sensor and the electrical connection point, the welding process is automated and coordinated, significantly shortening the wheelchair frame welding cycle and improving processing accuracy.
