Abstract
The utility model discloses an atmospheric pressure welds welder suitable for big cross -section plastic welding, including air duct and nozzle. Wherein, the air duct comprises annular air duct, air duct amplification pipe and intake pipe, air duct amplification pipe is drawn forth from eight directions of annular air duct, and the obverse and reverse evenly distributed of annular air duct and air duct amplification pipe has the nozzle, and the nozzle passes through threaded connection's form and annular air duct and air duct amplification pipe zonulae occludens, intake pipe department is provided with the internal thread, and the convenience is connected with the combustion gas trachea. Adopting this kind of atmospheric pressure to weld welder and changeeing the automation and batchization that realizes welding production, and then avoided because the unstable problem of quality that manual operation brought, this kind of atmospheric pressure welds welder and has expanded the gaseous operating range who welds, has more avoided gaseous problem of welding the welding quality unstability, and welding process is simple, can reach higher quality level, the equipment investment is little, the economical rationality.
Description
Technical field
The utility model relates to a kind of gas pressure welding welding gun, is specifically related to a kind of gas pressure welding welding gun being applicable to heavy in section Plastic Welding.
Background technology
The welding of plastics is always the problem that industrial circle warmheartedness is paid close attention to, and the quality of its welding quality directly affects the serviceability of product.The essence of Plastic Welding is that heat energy acts on faying face to be welded, the plastic molecules of interface overcomes Van der Waals force to reconfigure under the effect of outside energy, permeates each other, forms complete solder joint after cooling, in order to arrive more preferable welding effect, it is sometimes desirable to two plastic parts is pressurizeed.
According to the difference of heat source, Plastic Welding substantially can be divided into following a few class: ultrasonic bonding, laser welding, hot plate welding, friction welding, radial friction welding, track friction welding, induction welding, hot air welding etc..These welding methods have respective limitation, lack scientific and reasonable welding method at present especially for heavy in section Plastic Welding, it is seen that still have the space of lifting further in the field of heavy in section Plastic Welding.
Summary of the invention
In order to solve above-mentioned technical problem, the utility model provides a kind of gas pressure welding welding gun being applicable to heavy in section Plastic Welding, including wireway and nozzle.Wherein, wireway is made up of annular wireway, wireway amplification pipe and air inlet pipe；Wireway amplification pipe is drawn from eight directions of annular wireway, and the obverse and reverse of annular wireway and wireway amplification pipe is evenly distributed with nozzle, the form that nozzle is threaded connection and annular wireway and wireway amplification pipe compact siro spinning technology；It is provided with internal thread at air inlet pipe, is conveniently connected with burning gases tracheae.
The utility model has the advantages that
A kind of gas pressure welding welding gun being applicable to heavy in section Plastic Welding of the present utility model, compared with conventional plastic welding methods, it is more suitable for the welding of heavy in section plastics, and is easily achieved mechanical automation welding, while producing in enormous quantities, also make welding quality higher, more stable.This gas pressure welding welding gun structure is rationally, easy to maintenance, uses cheap gas to do comburant so that it also has good economic benefit.

1. annular wireway；12. wireway amplification pipes；13. air inlet pipe；2. nozzle.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, so that those skilled in the art can be better understood from the utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As it is shown in figure 1, a kind of gas pressure welding welding gun being applicable to heavy in section Plastic Welding of the present utility model, including wireway and nozzle 2.Wherein, wireway is made up of annular wireway 1, wireway amplification pipe 12 and air inlet pipe 13；Wireway amplification pipe 12 is drawn from eight directions of annular wireway 1, and the obverse and reverse of annular wireway 1 and wireway amplification pipe 12 is evenly distributed with nozzle 2, the form that nozzle 2 is threaded connection and annular wireway 1 and wireway amplification pipe 12 compact siro spinning technology；It is provided with internal thread at air inlet pipe 13, is conveniently connected with burning gases tracheae.
nullDuring use，Two fixtures are used in advance to be installed respectively two plastic parts to be welded，Certain distance is had between two plastic parts，The gas pressure welding welding gun this kind being applicable to heavy in section Plastic Welding extends between two plastic parts，The tow sides of welding gun cross section with two plastic parts respectively is parallel to each other，Start the source of welding current，Open aspirated switch，Owing to air inlet pipe 13 and burning gases tracheae connect，So fuel gas enters annular wireway 1 and wireway amplification pipe 12 along with air inlet pipe 13，Finally arrive nozzle 2，Pilot gas，I.e. produce high temperature bluster at each nozzle 2，The nozzle 2 of welding gun positive and negative is respectively to two plastics cross section heating，But when two cross sections become viscosity flow state，Stop heating，Removal welding gun，Two fixtures drive two plastic parts close to each other under the driving of drive system subsequently，Two plastic parts produces certain pressure under the effect of two fixtures，Extrude the impurity between two plastics cross sections and unnecessary viscosity flow shape plastics，Keep pressure a period of time，Make to combine together between two plastic parts，Complete solder joint it is formed for after cooling，Form firm strand，Reach the purpose of welding.This kind of gas pressure welding welding gun is used to be more easy to realize automation and the mass of welding production, and then avoid the problem that the quality brought due to manual operation is unstable, this kind of gas pressure welding welding gun extends the operation strategies of gas weldering, more avoid the problem that gas weldering welding quality is unstable, welding procedure is simple, can reach better quality level；Equipment investment is little, economical rationality.
Embodiment described above is only the preferred embodiment lifted by absolutely proving the utility model, and protection domain of the present utility model is not limited to this.The equivalent that those skilled in the art are made on the basis of the utility model substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
