Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1 and accompanying drawing 2, a kind of argon arc welding tube connector that the utility model provides, comprise the first tube connector 1 and second tube connector 2 of hollow, dock with one end of the second tube connector 2 one end of described the first tube connector 1, in described the first tube connector, be provided with the first plugged zone 3, in the second tube connector, being provided with the second plugged zone 4, the first plugged zones 3 and the first tube connector is tightly connected; The second plugged zone 4 and the second tube connector interference fits or matched in clearance, the first plugged zone 3 middle parts are provided with opening, and the air inlet pipe 5 that passes into argon gas stretches into and passes opening from the other end of the first tube connector;
On described the second plugged zone 4, be fixed with gas permeable material 6, between described the first plugged zone 3 and the second plugged zone 4, be connected with metallic bond 7.
Argon arc welding chain of the present utility model is taken in use, first on the second plugged zone 4, fix gas permeable material 6, be specially, circumferentially be fixed with sharp-pointed metal object or metal hanger at plugged zone, by the mode being wound around, poromeric material is fixed on the second plugged zone 4, again the second plugged zone 4 that winds gas permeable material 6 is put into the second tube connector afterwards, afterwards air inlet pipe 5 is stretched into from the other end of the first tube connector, and stretch out from one end, the first plugged zone 3 is enclosed within air inlet pipe 5 and is fixed, fixing mode is a variety of, can adopt binding wire, buckle, the modes such as hook, afterwards the first plugged zone 3 is put into the first tube connector.
The two ends of metallic bond 7 are separately fixed on two plugged zones, metallic bond 7 can be for multiple with being connected of two plugged zones, in the present embodiment, the both ends of metallic bond 7 are provided with hook, the two ends of metallic bond 7 are fixed on the first plugged zone 3 and the second plugged zone 4 by hook respectively, certainly, this is a kind of embodiment wherein, as long as can realize, metallic bond 7 is firmly fixed on plugged zone, in addition, the material of metallic bond 7 is iron chains in the present embodiment, ensure in the process of argon arc welding, can there is not hot melt phenomenon in metallic bond 7, certainly, can adopt more resistant to elevated temperatures metal material to make.
The fixing of metallic bond 7 might not be implemented after two plugged zones are all put into tube connector, can complete in any step before, and the utility model does not do concrete restriction, and the hook being connected with the first shutoff pipe in addition can directly hang in air inlet pipe 5 again.
After above-mentioned operation completes, just can be by the docking of two tube connectors, and by electrode holder the junction towards the first tube connector and the second tube connector, in two tube connectors, pass into argon gas by air inlet pipe 5 afterwards, complete the welding of two tube connectors.
After weld job completes, due to the connection function of metallic bond 7, then can directly the first plugged zone 3, the second plugged zone 4 and environment-friendly materials etc. all be pulled out outside pipe when reclaiming air inlet pipe 5, can reuse.
It should be noted that in the utility model, the first plugged zone 3 and the first tube connector are tightly connected; The second plugged zone 4 and the second tube connector interference fits or matched in clearance, this be because, if two plugged zones are be all sealed and matched (being interference fit), can make whole air chamber be positioned at the state of a sealing, and due to pressure differential, argon gas will spill from the joint portion between two tube connectors, and at this moment electrode holder just can not effectively weld two tube connectors, easily occurs the situations such as crackle.
Therefore, in the present embodiment, the first plugged zone 3 of the input of argon gas is for closely cooperating, and the second plugged zone 4 of the output of argon gas is for coordinating more loose fit system, when argon gas is inputted between the first tube connector 1 and the air chamber of the second tube connector 2 time, have a small amount of argon gas from coordinating more loose plugged zone to discharge, alleviate the too large problem of air chamber argon pressure.
Further, because may making plugged zone, loosening cooperation is difficult to fix, easily fall in the second tube connector 2, and between plugged zone and the second tube connector 2, excessive gap also can make argon gas flow out too much, therefore in the present embodiment, on the second plugged zone 4, be provided with gas permeable material 6, realize ventilative in, can not ensure larger gap yet.
In the present embodiment, described plugged zone is rubber, rubber is a very general leftover bits and pieces in daily factory process process, and tradition is all that rubber is directly abandoned, cause waste, the utility model says that rubber processes again exactly, manufacture plugged zone, economize on resources, and processing cost is low, without other auxiliary plugging devices.
Certainly, the utility model does not limit a kind of embodiment that plugged zone is rubber, then in other embodiment, described plugged zone is PVC layer or Polypropylence Sheet etc.
In the present embodiment, described gas permeable material 6 is sponge or fire retardant, and in guarantee period gas permeability, the effect of the certain dustproof and sealing of also playing, simultaneously by coordinating with hook structure, also can accomplish simply readily removablely, changes effect easily.
Certainly, do not limit the gas permeable material 6 of above-mentioned material in the present embodiment, in other embodiment, described gas permeable material 6 also can adopt conventional toilet paper or newspaper etc., and the utility model does not do concrete restriction.
In the present embodiment, one end of described the first plugged zone 3 and the first tube connector and one end of the second plugged zone 4 and the second tube connector distance are 100-150mm, in traditional argon arc welding tube connector, the distance of two plugged zones and tube connector one end is all less than 100mm, this is because traditional welding procedure thinks that this length can ensure the complete of weld seam, and be convenient to the taking-up of plugged zone, applicant is through finding in long-term enforcement and test, after the length of plugged zone and welding position is lengthened, the length that is air chamber lengthens, and the pressure of the argon gas of adaptive change input, for example, in the present embodiment, the gas transmission end of described air inlet pipe 5 connects argon tanks, in described argon tanks, fill the argon gas of 12-15Pa, pass through this set, effectively increase the gas recoverable amount between pipeline, be conducive to protect weld bond, make the better effects if of final welding.
The argon arc welding tube connector of new structure, can effectively protect integrality and the sealing of weld seam, simple in structure, convenient welding, and applied widely, and plugged zone and gas permeable material 6 can recyclings in addition, and cost is satisfactory for result.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
