Abstract
The invention relates to a gas distribution device of shielding gas for welding. The gas distribution device comprises a gas supply box, a gas outlet pore plate A and a gas outlet pore plate B. The gas supply box is columnar, the inner wall of the gas supply box is in a thread shape, and a gas supply opening is formed in the lower end of the gas supply box in a transition manner. The gas outlet pore plate A and the gas outlet pore plate B are flatly columnar. The side walls of the gas outlet pore plate A and the gas outlet pore plate B are in a thread shape, and the gas outlet pore plate A and the gas outlet pore plate B are in threaded connection with the inner wall of the gas supply box. A plurality of through holes A are evenly formed in the gas outlet pore plate A, and a plurality of through holes B are evenly formed in the gas outlet pore plate B. The through holes A and the through holes B are vertically staggered. The gas distribution device has the beneficial effects that most components of the gas distribution device of shielding gas for welding are of a detachable structure, high adaptability is achieved, convenience and flexibility are achieved, and mounting and operating are easy; meanwhile, through holes A and the through holes B in the device are vertically staggered and used for increasing gas flowing resistance, so that gas supply is more even; and meanwhile the upper end of the gas supply box is connected with a contact detachably, the proper contact can be selected according to the shape of a welded end face, and therefore use is quite convenient.
Description
Technical field
The present invention relates to a kind of distribution device, particularly one welding protection gas distribution device.
Background technology
Welding is one of mode that two separators are effectively fixed, and gas shielded arc welding wherein is also indispensable a kind of welding manner.In the middle of use gas shielded arc welding soldering stainless steel process, in order to ensure weldquality, under needing to make the back side also remain on the atmosphere of protective gas when welding former road.When generally needing operating personnel's hand-held simple gas protective device, gas shield is done at the butt welded seam back side, and such method not only consumes manpower but also do not have good effect, is especially more difficult to operation when welding Circumferential Welds In Cylinders, and operating efficiency reduces; Therefore people need the protection-gas welding distribution device that constantly a kind of gas distribution of development is convenient, simple to operate and applied widely, through retrieval, do not find the same or analogous technical scheme with the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of gas distribution protection-gas welding distribution device convenient, simple to operate and applied widely.
For solving the problems of the technologies described above, technical scheme of the present invention is: gas distribution device is protected in a kind of welding, and its innovative point is: comprise air feed box, the orifice plate A and the orifice plate B that gives vent to anger that gives vent to anger be arranged in air feed box;
Described air feed box is column, and inwall is shape of threads, and lower end transition arranges an air supply opening;
The described orifice plate A and the orifice plate B that gives vent to anger that gives vent to anger is flat column shape, and sidewall is shape of threads, and is connected with air feed box inner thread; The described orifice plate A that gives vent to anger evenly arranges some through hole A, the orifice plate B that gives vent to anger evenly arranges some through hole B; Described some through hole A and some through hole B stagger setting up and down.
Further, outside, described air feed box upper end is in shape of threads, and the contact head that is threaded, described contact head is thin wall shape.
Further, the end of described contact head is wound around resistance to guncotton.
Further, orifice plate A side of giving vent to anger described in arranges an annular jacking block.
The invention has the advantages that:
(1) parts of protection-gas welding distribution device mostly are demountable structure, and strong adaptability is convenient, flexible, install, simple to operate; In this device, some through hole A and some through hole B stagger setting up and down simultaneously, for increasing gas flow resistance, make air feed evenly.
(2) outside, air feed box upper end is in shape of threads, and the contact head that is threaded, this kind connects detachable, and can select suitable contact head according to the shape of welding end surface, uses very convenient.
(3) end of contact head is wound around resistance to guncotton, increases sealing and can protect weldment not by the scratch of air feed box simultaneously.
(4) orifice plate A side of giving vent to anger arranges an annular jacking block, and the orifice plate A that prevents from giving vent to anger occurs to loosen and is ejected, and vibrational power flow is reasonable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of protection-gas welding distribution device of the present invention.
Fig. 2 is the structural representation of give vent to anger orifice plate A and the orifice plate B that gives vent to anger of a kind of protection-gas welding distribution device of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, the invention discloses a kind of protection-gas welding distribution device, comprise air feed box 1, the orifice plate A4 and the orifice plate B3 that gives vent to anger that gives vent to anger be arranged in air feed box 1.
Air feed box 1 is in column, and inwall is shape of threads, and lower end transition arranges an air supply opening 2; Air feed box 1 upper end outer wall is shape of threads, and the contact head 6 that is threaded, the end of this contact head 6 is wound around resistance to guncotton 7.
The orifice plate A4 and the orifice plate B3 that gives vent to anger that gives vent to anger is flat column shape, and sidewall is shape of threads, and is connected with air feed box 1 inner thread; Give vent to anger on orifice plate A4 and evenly arrange some through hole A9, side arranges an annular jacking block 5, and this annular jacking block 5 is connected with air feed box 1 inner thread; Give vent to anger on orifice plate B3 and some through hole B8 are evenly set; Some through hole A9 and some through hole B8 stagger setting up and down.
When protection-gas welding distribution device uses, first select suitable contact head 6 according to the shape of welding end surface, and be connected with air feed box 1 outer wall thread; Then covered in to-be-welded pieces by contact head 6, and in air feed box 1, pass into protection gas from air vent 2, namely protection gas shed by some through hole B8 and some through hole A9 successively, effectively ensure that welding quality.
More than show and describe general principle of the present invention and principal character.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
