Automatic tube bender

Abstract

An automatic tube bender comprises a tube feeding mechanism, a heating mechanism, a tube bending mechanism, a forming mechanism and a tube discharging mechanism. The automatic tube bender has the advantages that the tube bender is quite suitable for the automatic tube bending of T12U florescent lamp tubes, labor intensity of workers can be lowered, product quality can be increased, and the tube bender is simple and reasonable in structure and high in work reliability.

Description

technical field [0001] The invention relates to technical equipment for manufacturing lamps, in particular to an automatic pipe bending machine for U-shaped lamps of fluorescent lamps. Background technique [0002] Fluorescent lamps, which combine fluorescent tubes and ballasts into a whole lighting device, are an important energy-saving lamps like LED lamps. Among them, according to the shape of the fluorescent tube, it can be divided into three types: U-shaped tube, spiral tube and straight tube. Further, U-tubes have various specifications such as T2U, T3U, T4U, T6U, T8U, T10U and T12U, which are often used in homes, hotels, schools, hospitals, etc. High [5-6 times that of ordinary bulbs], small size and good color rendering. "T" in "T2U" represents the pipe diameter, and "2" represents the specific value of the pipe diameter in inches. In theory, the thinner the tube, the higher the efficiency, which means that the same wattage emits more light. In actual use, the th...

Problems solved by technology

"The problem with this patent is that it cannot be applied to the bending pipe processing in the production of T12U products.

[0004] 1. The production efficiency is low, the output is only 60 pieces / hour;

[0005] 2. High requirements for employees, requiring high skills and proficiency;

[0006] 3. The labor intensity of employees is high, affected by human factors, the pass rate is only about 85%, and the product consistency is poor;

[0007] 4. There are many operators, a large area is occupied, and the production cost is high;

[0008] 5. Due to the large diameter of the T12U lamp tube, the softened glass frit at the elbow is easy to fall, which leads to poor shaping of the elbow, which affects the pass rate;

[0009] 6. Due to the large opening of the product and the large diameter of the tube, the wall thickness difference between the inner and outer sides of the glass tube at the elbow is large, which affects the quality of the T12U lamp tube
