Technical Field

[0001] The utility model relates to an ultraviolet lamp tube bending machine, belonging to the technical field of ultraviolet lamp tube processing equipment. Background Art

[0002] Ultraviolet disinfection lamps are also called ultraviolet germicidal lamps and ultraviolet fluorescent lamps. Ultraviolet disinfection lamps radiate ultraviolet rays with a wavelength of 253.7nm. Ultraviolet rays in this band have the strongest bactericidal ability and can be used to disinfect water, air, clothing, etc. Ultraviolet disinfection and sterilization are widely used. Now the demand for ultraviolet disinfection lamps is getting higher and higher. In the process of processing ultraviolet lamp tubes, sometimes the lamp tubes need to be bent.

[0003] In the prior art, after the bending part of the ultraviolet lamp tube is softened by high-temperature baking, the ultraviolet lamp tube is bent into a V-shape or a U-shape by a bending mechanism, and a protective gas is blown into the ultraviolet lamp tube at the same time; since the bending part of the ultraviolet lamp tube has been softened after being baked at high temperature, if the wind force when blowing the protective gas is not well controlled, the bending part of the ultraviolet lamp tube is easily affected by the wind force of the protective gas to produce inward contraction or expansion deformation (expansion when the wind force of the protective gas is too large, and contraction when the wind force of the protective gas is too small), which affects the bending quality.

[0004] Therefore, how to provide a UV lamp bending machine with stable bending quality is the research purpose of the utility model. Utility Model Content

[0005] In view of the deficiencies of the above-mentioned technology, the utility model provides an ultraviolet lamp tube bending machine, which limits the periphery of the bending part of the ultraviolet lamp tube through a mold mechanism, and blows in protective gas with sufficient wind force at the same time, so that the bending part of the ultraviolet lamp tube will not shrink or expand, thereby improving the stability of the bending quality.

[0008] Furthermore, the base includes a bottom plate and a movable plate, the movable plate is installed on the bottom plate through a slide rail slider, and one end of the movable plate is connected to a movable cylinder for driving the movable plate to move.

[0009] Furthermore, the front mold and the rear mold are mounted on the movable plate via a slide rail slider, and the heating mechanism is fixedly mounted on the movable plate via a mounting seat.

[0010] Furthermore, a cavity is also provided on a side of the front mold away from the rear mold, and on a side of the rear mold away from the front mold.

[0011] Furthermore, one group of the bending dies is connected to a motor for driving the bending dies to flip via a transmission shaft, and drives the other group of the bending dies to flip via gears.
