The invention provides a radiant flame heating furnace for solving the problems of low production efficiency, easy damage and high maintenance cost of an electric heating part of a glass tube of the existing spiral lamp tube bending (forming) machine, and the radiant flame heating furnace has the advantages of good uniformity of heating the glass tube, high temperature stability, fast temperature increase and stabilization of a furnace chamber, difficult damage and capabilities of reducing the maintenance, reducing the power consumption, improving the productivity and reducing the using cost. The radiant flame heating furnace comprises a front furnace body and a back furnace body which are relatively arranged at an interval, and the furnace chamber is formed between the front furnace body and the back furnace body; fire head bodies are respectively arranged on the front furnace body and the back furnace body, each fire head body comprises a radiant surface which is concave inwards to form the shape of a bowl, and the bowl-shaped radiant surfaces of the fire head bodies on the front furnace body and the back furnace body are oppositely arranged; a fire hole which is parallel to the central axial line of each bowl-shaped radiant surface and communicated with a gas source is arranged at the center of the bottom of each bowl; baffle plates for reflecting flames jetted from the fire holes to the bottoms of the bowls are arranged near to the bottom parts of the bowls and at the front ends of the fire holes; and the radiant flame heating furnace further comprises a glass tube clamping mechanism for clamping two ends of the glass tube which penetrates the furnace chamber.
Description
technical field [0001] The invention belongs to the technical field of electric light source manufacturing and mechanical equipment, and is a novel radiant flame heating furnace, which is used for manufacturing spiral glass tubes of spiral fluorescent lamps. technical background [0002] Since the development of compact fluorescent lamps (commonly known as energy-saving lamps), they have become a big family in the field of electric light sources: there are U-shaped, spiral-shaped, H-shaped, lotus-shaped, double-C-shaped, ring-shaped and other series of fluorescent lamps. Among these energy-saving lamps, spiral energy-saving lamps are the most excellent. Compared with the above-mentioned other series of lamps with the same power, spiral fluorescent lamps: 10% higher luminous efficiency, 15% longer life, high intensity, more compact structure, symmetrical and uniform light distribution curve And so on, it is deeply loved by users. But its output, scale and degree of automatio...
