Abstract
The utility model relates to an oxyacetylene plastic welding tool belonging to a welding tool. The utility model is characterized in that an acetylene gas inlet is directly connected with an acetylene gas channel through an acetylene gas valve; flat segments with different length and bore diameters can be adopted to form an angular contact with a combustion chamber to form a welding nozzle; the connecting nuts of the combustion chamber is used to connect the welding nozzle and the welding tool into a whole body; the design can shorten the length of the welding toll and reduce the weight, and the use is convenient; different length and bore diameters of the flat plane can be adopted according to the conditions of weldments; the melting area of a welding master batch is reduced, and the welding quality is improved; welding nozzles with different oblique angles can be adopted according to field working conditions to adapt complex job environments.
Description
The utility model relates to a kind of plastics soldering set.
In the prior art, electrothermal plastics soldering set is arranged, but can not also be not easy to the frequent place operation of changing in operating point at power free field operation.Another kind is oxy-acetylene metal, the dual-purpose soldering set of plastics, and it is to cut tool by G01-30 type jet absorption type metal to convert, and promptly pulls down the oxygen cutting nozzle, but with regard to welding plastic.This soldering set is made up of combustion-supporting oxygen inlet (1), acetylene gas import (2), acetylene air valve (3), handle (4), combustion-supporting oxygen valve (5), control valve (6), combustion-supporting oxygen channel (7), acetylene gas passage (8), combustion chamber attaching nut (9), combustion chamber (10), flat segments (11) as shown in Figure 1.Accompanying drawing 2 is enlarged drawings of combustion chamber (10) and flat segments (11).The oxy-acetylene soldering set of the G01-30 type transformation of the way is as welding plastic, and soldering set is long, overweight, and operation inconvenience causes inefficiency, more seems heavy when the horizontal position welding in especially narrow in the scope of operation or high-altitude, vertical position welding, overhead welding operation; To the dark and narrow operation of pad, be difficult to implement; Thermal current passway is that the length L of flat segments (11) is very short, and thermal current is not concentrated, and is big to the melting area of welding masterbatch, influences welding quality.
The utility model is intended to overcome the deficiencies in the prior art and a kind of oxy-acetylene plastics soldering set of designing.
The purpose of this utility model can realize by following measure:
Exempt from control valve (6), to alleviate the weight of soldering set.Because control the size that combustion-supporting oxygen valve (5) and acetylene air valve (3) are enough to regulate flame combustion chamber.Shorten combustion-supporting oxygen channel (7), acetylene gas passage (8) and handle (4), to shorten the length of soldering set body.Because during welding plastic, thermal radiation intensity is low, and it is feasible shortening soldering set length.Can make soldering set light and handy like this, handled easily.
Another measure that realizes the purpose of this utility model is the length L that increases flat segments (11), rationally matches its aperture.Flat segments (11) length L of existing oxy-acetylene soldering set only is the wall thickness of combustion chamber (10), and length L is too small with the ratio in aperture, and hot gas too disperses after flowing out flat segments (11), makes that the melting area of welding masterbatch is big.The utility model length L of flat segments (11) that extended, and select suitable aperture makes the ratio in length and aperture suitable, and hot gas flows out after the flat segments (11) more concentrated.Can select different flat segments length L and suitable aperture for use according to the conditions such as thickness of thickness, shape and the welding rod of weldment.
The 3rd measure that realizes the purpose of this utility model is to make flat segments (11) become an oblique angle with the soldering set body of handle (4), combustion-supporting oxygen channel (7), acetylene gas passage compositions such as (8), and make this angle replaceable in wider scope, adapting to the dark and narrow operation of downhand welding, overhead welding, horizontal position welding, vertical position welding and solder joint, and on-the-spot narrow operation.For realizing this purpose, flat segments (11) is connected with certain oblique angle with combustion chamber (10), constitutes weldering and chews, and this angle can be selected for use between 90～180 ℃.Utilize combustion chamber attaching nut (9), the combustion chamber that weldering is chewed (10) are connected as straight line with the soldering set body, like this, and flat segments (11) and soldering set body bevel.Utilize combustion chamber attaching nut (9), can chew according to the weldering that operating condition is changed the flat segments (11) of different length, aperture and gradient.
Adopt the oxy-acetylene plastics soldering set of the utility model design, lightly nimble, the weld job of various occasions and the weldment of different shape can be adapted to, thereby the quality and the operating efficiency of welding can be significantly improved.
The drawing of accompanying drawing is described as follows:
Accompanying drawing 1 is oxy-acetylene metal, the dual-purpose soldering set of plastics;
Accompanying drawing 2 is the combustion chamber (10) and the flat segments (11) of oxy-acetylene metal, the dual-purpose soldering set of plastics;
Accompanying drawing 3 is oxy-acetylene plastics soldering sets;
Accompanying drawing 4 is the combustion chamber (10) and the flat segments (11) of oxy-acetylene plastics soldering set.
Below in conjunction with embodiment the utility model is done further statement:
Claims (3)
1, a kind of oxy-acetylene plastics soldering set, form by combustion-supporting oxygen inlet (1), acetylene gas import (2), acetylene air valve (3), handle (4), combustion-supporting oxygen valve (5), control valve (6), combustion-supporting oxygen channel (7), acetylene gas passage (8), combustion chamber attaching nut (9), combustion chamber (10), flat segments (11), it is characterized in that acetylene gas import (2) behind acetylene air valve (3), directly be connected with acetylene gas passage (8); Flat segments (11) is connected as the oblique angle with combustion chamber (10), and combustion chamber (10) are connected as straight line with the soldering set body.
2, by the described oxy-acetylene plastics of claim 1 soldering set, it is characterized in that the aperture of flat segments (11) is selected 3～5 millimeters for use, the length of flat segments (11) is selected 6～16 times of aperture for use, and optimum value is 9～11 times.
