The lighting tube heating mechanism of lighting tube bender for ring fluorescent lamp
Technical field
The present invention relates to the lighting tube heating mechanism of ring fluorescent lamp.
Background technology
At present, the duration and degree of heating of the lighting tube heating mechanism of lighting tube bender for ring fluorescent lamp is for stamping aperture depositing on the air drain, is welded on the aperture of depositing air drain with copper pipe one by one to form.In manufacturing processed, copper pipe is difficult to be welded in place, need debug, by hand duration and degree of heating be adjusted to the optimum position one by one, after the working hour is long, duration and degree of heating copper pipe easy deformation, cause the Glass tubing heating inhomogeneous, therefore need often to adjust the duration and degree of heating copper pipe, simultaneously, the duration and degree of heating copper pipe also is not durable, and can not regulate the flame size of single duration and degree of heating.
Summary of the invention
Technical problem to be solved by this invention provides a kind of manufacturing and regulates simply the lighting tube heating mechanism of the lighting tube bender for ring fluorescent lamp of long service life.For this reason, the present invention by the following technical solutions: it comprises main body, in a row offers the duration and degree of heating hole on the described main body, and described duration and degree of heating hole is the big stepped hole of the little rear portion of anterior internal diameter internal diameter, is provided with the bolt of regulating flame size at the big hole Duan Chu of described internal diameter.Owing to adopt technical scheme of the present invention, make the duration and degree of heating integrated design of lighting tube heating mechanism, can utilize machining equipment to make easily during fabrication, can not be out of shape long service life, do not need often to adjust duration and degree of heating, can also regulate the flame size of single duration and degree of heating, make the Glass tubing even heating, finished product is attractive in appearance, the production efficiency of machine is improved, and quality product is more excellent.
Description of drawings
Fig. 1 is the main body front view of a kind of embodiment provided by the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
Fig. 4 is the main end out line figure of embodiment provided by the present invention.
Embodiment
With reference to accompanying drawing.The present invention includes main body 1, in a row offer the duration and degree of heating hole on the described main body, described duration and degree of heating hole is the big stepped holes of anterior 2 internal diameters little rear portion 3 internal diameters, is provided with the bolt 6 of regulating flame size at big hole section 3 places of described internal diameter.
Above-mentioned " in a row offering on the main body " can be that to offer also can be to offer doublely or offer more with arranging singlely, and when for double or arrange when establishing, adjacent row's duration and degree of heating hole can be also can staggering of alignment more.
Regulate for convenience and make between the duration and degree of heating hole for reasonably closely, so that to the even heating of glass-tube, as shown in the figure, in the present embodiment, the adjacent front and back position of described bolt on main body staggers.
Main body offers at rear, duration and degree of heating hole and deposits air drain 4, and the notch of depositing air drain is provided with the shrouding 7 of band connecting hole; In the present embodiment, the cross-sectional profiles of described main body is the thick double step shape in anterior thin rear portion, i.e. step 51 as shown in the figure and step 52, the glass-tube heating operation of being more convenient for like this, and in the adjacent described bolt one be located under the step that another is located on the step, like this, the step edge line is presented down the line of delimitation of regulating bolt, thereby is convenient to the correspondence identification to duration and degree of heating and bolt.
The air inlet gas circuit that air drain is deposited in air valve that the present invention adopts control, the inlet pipe of drawing reference numeral 8 for depositing air drain, it links to each other with connecting hole on the shrouding 7, and connecting hole also can not be located on the shrouding and is arranged on and deposits the air drain place on the main body certainly, is provided with water-and-oil separator between inlet pipe 8 and air valve.Air valve and water-and-oil separator in the drawings do not draw.
During work, open air valve, light duration and degree of heating after, the flame size of the single duration and degree of heating of manual adjustment as required.
