Abstract
The utility model belongs to a welding torch nozzle that gas feed was welded and is used.
The utility model discloses include the nozzle body of taking gas passage with welding torch threaded connection, cup jointed the core of taking gas passage in the nozzle body, it has the clitellum cavity to enclose between core and the nozzle body, is equipped with the through-hole on the core, intercommunication gas passage and clitellum cavity, gaseous exit end has the binding off. The utility model discloses simple structure, sealed reliable, gaseous difficult leakage, simple to operate, increased the face of preheating, make gaseous abundant burning, difficult emergence oxidation has improved welding quality.
Description
The utility model belongs to a kind of torch-tip of air feed weldering usefulness.
Present employed oxyhydrogen welding cut machine, it has advantages such as simple in structure, easy to operate, safe and reliable, pollution-free, that use cost is low, and in use the material of Xiao Haoing is a pure water, therefore is subjected to very much user's welcome.But in existing technology, the tip of oxyhydrogen welding cut machine is traditional acetylene-oxygen tip, and this tip centre has only gas passage orifices one, it is fast to exist air-flow, workpiece gives the long-pending little phenomenon of hot side, to the weldment of unlike material, operating temperature realizes by adjusting welding torch acetylene and amount of oxygen ratio and flow.But the hydrogen-oxygen tolerance of oxyhydrogen welding cut machine is more fixing than, therefore can't adjust temperature, use traditional tip to carry out the hydrogen-oxygen gas welding, exist that flow velocity is fast, to give heat not enough, phenomenons such as surface of the work oxidation, only by adjusting the distance that throughput is difficult to change flame, consequence is that oxidation is arranged, and welding quality is difficult to guarantee.
The purpose of this utility model is to address the above problem, and provides a kind of sealing simple in structure, easy, combustion gas to be difficult for leaking, and changes conveniently, improves welding quality and gives heating power, prevents the oxyhydrogen welding cut machine torch-tip of oxidation.
The utility model includes the nozzle body of the band gas passage that is threaded with welding torch, in nozzle body, be socketed with the core body of band gas passage, be with the endless belt cavity between core body and the nozzle body, on core body, be provided with through hole, be communicated with gas passage and endless belt cavity, the port of export of gas has closing in.
The utility model simple structure, sealing is reliable, gas is difficult for leaking, easy for installation, increased and given hot side, make full combustion of gas, be difficult for oxidation takes place, improved welding quality.
Accompanying drawing is the utility model structural representation.
As shown in drawings, the utility model includes the nozzle body 1 of the band gas passage that is threaded with welding torch, in nozzle body 1, be socketed with the core body 4 of band gas passage, be with endless belt cavity 5 between core body 4 and the nozzle body 1, on core body 4, be provided with through hole 3, be communicated with gas passage 6 and endless belt cavity 5, the port of export of gas has closing in.When gas enters gas passage 6, form two-way and penetrate and be sprayed onto on the workpiece, gas passage 6 carries out soldering flame usefulness, and another road forms together insulation uniformly around soldering flame and gives hot wall through the endless belt cavity, and gas flow rate is reduced, and can improve welding quality and give heating power.Because core body 4 is socketed in the nozzle body 1, it has only sealing part one, easily seal and process, and sealing is reliable.As shown in drawings, boss 2 is arranged on core body, boss 2 is stuck on the gas passage face of nozzle body.During use core body is put into nozzle body, nozzle body is positioned on the welding torch just can uses, operation is very easy, adds man-hour, can not change the external structure and the connecting thread size of former tip.
Claims (2)
1, a kind of oxyhydrogen welding cut machine torch-tip, it includes the nozzle body of the band gas passage that is threaded with welding torch, it is characterized in that in nozzle body, being socketed with the core body of band gas passage, be with the endless belt cavity between core body and the nozzle body, on core body, be provided with through hole, be communicated with gas passage and endless belt cavity, the port of export of gas has closing in.
2, nozzle according to claim 1 is characterized in that boss is arranged on the core body, and boss is stuck on the gas passage face of nozzle body.
