Abstract
The utility model discloses an annular-tube torch without a nozzle which relates to the construction machinery and is suitable to be used in the steel bar air pressure welding machine to heat the steel bar to be welded. The existing welding torch is the annular-tube welding torch with a lot of nozzles, so the manufacturing technology is comparatively complicated, the volume is big, a lot of material is used, and the nozzle hole is blocked easily. The utility model is provided with a plurality of small holes which can eject flame directly on the tube wall of the annular tube with an opening without a nozzle. So the annular-tube torch without nozzle has advantages of easy fabrication, small size and light weight, saving the material and having the uneasily blocked nozzle.
Description
A kind of nothing that is installed on the gas welding torch is chewed the endless tube welding torch, relates to building machinery, is applicable to that steel bar gas connects the steel bar gas that uses in the technology and meets sb. at the airport.
Known steel bar gas is met sb. at the airport, and mainly is made up of heater, pressurizer and clamper, and wherein heater is made up of gas welding torch and the endless tube welding torch of chewing that is contained on the gas welding torch more.It is this that known that to chew the endless tube welding torch be that several taper nozzles have been installed on an endless metal pipe is more.The gaseous mixture of combustible gas and oxygen is sprayed through each taper nozzle by endless tube again during work.This endless tube welding torch of chewing needs each taper nozzle is fixed on the endless metal pipe during fabrication, thus manufacturing process complexity, and welding torch physical dimension and weight are bigger, and also more with material.The spray orifice of nozzle also is prone to clogging simultaneously.
Task of the present utility model provides a kind of, and manufacturing process is simple, volume is little, spray orifice in light weight is difficult for obstruction and saves the nothing that steel bar gas connects that is applicable to of material again and chew the endless tube welding torch.
For finishing above-mentioned task, the utility model is made of the endless metal pipe (hereinafter to be referred as endless tube) of a band opening.Establish a joint at the endless tube middle part, in order to be connected with gas welding torch; Both ends at endless tube are provided with plug; On the annular inboard tube wall of endless tube, have several apertures.The gaseous mixture of combustible gas and oxygen is directly sprayed by endless tube each aperture on tube wall during work.
The utility model more chewed the endless tube welding torch and is compared with known, but owing on tube wall, left the aperture of direct injection gas, need not nozzle, saved nozzle and the fixedly work of nozzle of manufacturing, so manufacturing process is simple, owing to saved nozzle, the annular diameter of endless tube is also corresponding to be dwindled, so the physical dimension of welding torch is dwindled again.Its weight saving is simultaneously saved with material, and welding torch outer surface treatment process also improves.Gaseous mixture is directly sprayed through aperture by endless tube in the endless tube welding torch owing to chewing in nothing again, so be difficult for stopping up.
Description of drawings:
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Number in the figure 1 is that endless tube, 2 is that aperture, 3 is that joint, 4 is plug.
Below in conjunction with drawings and Examples the utility model is explained in further detail, but the utility model is not limited by described embodiment.Fig. 1 and Fig. 2 are a kind of embodiment of the present utility model, joint 3 is positioned at the middle part of endless tube 1, plug 4 is loaded on the both ends of endless tube 1, several apertures 2 are distributed on the annular inboard tube wall of endless tube 1, and the center line of each aperture is positioned at same plane, each aperture center line points to the annular center position of endless tube 1, not having the endless tube of chewing welding torch during work is loaded on the gas welding torch, combustible gas in the welding gun and oxygen by joint 3 in endless tube 1, again through fully mixing by 2 ejections of each aperture, form multi beam flame through lighting, to heating equably around the reinforcing bar to be welded that is positioned at endless tube 1 annular center place.
Claims (1)
- Be used for the nothing that steel bar gas meets sb. at the airport and chew the endless tube welding torch, constitute, plug is housed, be provided with a joint that can link to each other at the middle part of endless tube with common gas welding torch at the two ends of endless metal pipe by the endless metal pipe of a band opening.Feature of the present utility model is, has several apertures 2 on the annular inboard tube wall of endless tube 1, and the center line of each aperture 2 is positioned at same plane, and the center line of each aperture 2 points to the annular center position of endless tube 1.
