Abstract
The utility model discloses a heating pipe for pre-welding heating, comprising a gas supply pipeline, a gas inlet pipe connected with the gas supply pipeline and a plurality of nozzles uniformly distributed on the gas supply pipeline, wherein the gas supply pipeline can be a straight pipe, a square pipe, an annular pipe or other proper shapes. As the nozzles are uniformly distributed on the gas supply pipeline, the large area of a workpiece can be heated uniformly.
Description
Technical field
The utility model relates to a kind of heating tube, particularly relates to the preceding heating of a kind of weldering and uses heating tube.
Background technology
In the workpiece welding job, often require weld preheating, especially in winter, weld preheating is welder's a important process.In present production, often adopt the grilled gun heating to carry out preheating, this method has significant limitation, and especially when winter, ambient temperature was relatively lower, workpiece was cool while baking, and the heating of this mode of heating is very inhomogeneous.
Summary of the invention
The technical problem that the utility model will solve provides a kind of device that can before welding, evenly heat workpiece.
For this reason, the novel technical scheme of taking of this usefulness is following:
Heating tube is used in heating before a kind of weldering, its by steam line, connect the air inlet pipe of this steam line and a plurality of nozzles of being evenly distributed on the said steam line are formed.
Said nozzle is a tubulose, preferably, on the tube wall of said nozzle, is formed with air admission hole, so that air can get into nozzle from said air admission hole when welding, the gas of supply can fully be burnt.
Said steam line is straight tube, rectangular tube, ring pipe or other suitable shape.
The heating tube of the utility model has remedied the deficiency of grilled gun, and the difference at the position that can heat is as required processed steam line different shapes such as straight tube, rectangular tube, ring pipe, adapts with the shape with workpiece.Because a plurality of nozzles are evenly distributed on the steam line, so can on large tracts of land, evenly heat workpiece.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the heating tube of the utility model.
Fig. 2 is the enlarged drawing of A portion among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing to the weldering of the utility model before heating describe with the structure of heating tube.
As shown in Figure 1, this heating tube forms 3 by nozzle 1, steam line 2 and air inlet pipe.During use, air inlet pipe 3 is connected with the grilled gun pipe, to guarantee having sufficient fuel gas and oxygen to be supplied to steam line 2 simultaneously, is evenly distributed with a plurality of nozzles 1 on the steam line 2, heat simultaneously the assurance many places, to realize the uniformity and the synchronism of weld preheating.
In the present embodiment, nozzle is a tubulose, and nozzle also can be other suitable shape certainly.For the gas that makes steam line 2 supplies can fully burn, on the tube wall of nozzle 2, also be formed with air admission hole 4, so that air can get into nozzle from said air admission hole when welding.
Claims (5)
1. heating tube is used in heating before the weldering, it is characterized in that: by steam line, connect the air inlet pipe of this steam line and a plurality of nozzles of being evenly distributed on the said steam line are formed.
2. heating tube is used in heating before the weldering according to claim 1, and it is characterized in that: said nozzle is a tubulose, on the tube wall of said nozzle, is formed with air admission hole.
