Abstract
The invention relates to a deep-hole plug, which comprises an aluminum plug end and a second plug end welded together with the aluminum plug end. The deep-hole plug is obvious in plugging effect, easy in control of a welding process and long in service life.
Description
Technical field
The invention belongs to the precision optical machinery field, relate to a kind of blocking device, relate in particular to a kind of deep hole plug.
Background technique
In project installation, the technological opening of some reservations after part completes, requires to carry out permanent shutoff, for example, has an aluminium sash part bigger, 3.5 kilograms of weight, and aluminium plug size is smaller, weight 1 gram.At present; In the time of in aluminium sash that the aluminum plug is packed into; Because the influence of factors such as when welding welding temperature too high and weld interval, though in the very fast melt flow hand-hole of aluminum plug and cause to seal or most of opening is blocked, still leave the part space; In the continuation field of some accurate controls, such space is not perhaps welded and is firmly often caused irremediable fault.For example, comprise that then infringement, Control Failure, the throwing mechanism of critical piece miscarrying takes place or lose the input ability or the inefficacy of weapon device constituent element in aircraft.
At present, in such microtechnology welding field, especially in welding, directly carry out the very difficult control of welding fabrication size in the built-up welding hole.Because the restriction of various welding conditions often can not realize permanent connection,, in long-time using process, come unstuck also can cause to connect and lost efficacy if adopt the method for glueing joint.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technique, the invention provides a kind of stop up effect obviously, the welding process easiness in handling and working life deep hole plug of a specified duration.
Technical solution of the present invention is: the invention provides a kind of deep hole plug, comprise aluminium plug end, its special way is: said deep hole plug also comprises the second plug end that welds together with aluminium plug end.
The above-mentioned second plug end is a metal or alloy.
When the above-mentioned second plug end was alloy, the said second plug end was Steel Alloy, titanium alloy or nickel alloy.
When the above-mentioned second plug end is Steel Alloy, when said aluminium plug end and the welding of Steel Alloy plug end, utilize aluminium base solder to carry out soldering.
Will be before above-mentioned aluminium plug end and the welding of Steel Alloy plug end to Steel Alloy plug end surfaces metal lining.
Metal to Steel Alloy plug end surfaces plating before above-mentioned aluminium plug end and the welding of Steel Alloy plug end is copper, nickel, zinc, silver or aluminium coat.
Advantage of the present invention is:
1, the obstruction effect is obvious.The present invention is with traditional plug; Especially the aluminum plug changes the double-deck plug of aluminium and other carbide alloy into; The present invention adopts the plug of the manufacturing of different materials well to solve the difficult problem that single plug is difficult to stop up, and in the present invention, aluminum one end of plug is realized being connected with part; Especially with the welding of aluminum hardware, can accomplish the melting welding of aluminium and aluminium; The other end material of plug guarantees the size in the hole because operating temperature Gao Buhui is soldered fusing.The plug that materials at two layers provided by the present invention is made makes the technological opening of reserving obviously to stop up, and the slit can not occur or leak stifled phenomenon.An end that contains aluminium can not be thrown off when guaranteeing the joint heating in the melting welding of realization and part voluntarily.
2, welding process easiness in handling.Plug provided by the present invention in use; Use same welding temperature and weld interval; Its outside alloy material layer also can go out at former opening and blocks firmly even contain the very fast melt flow hand-hole of aluminium end; Its welding or the process of sealing are easy to control, have improved the working efficiency of sealing greatly.
3, working life is of a specified duration.Plug provided by the present invention is because the alloy material that welds together with aluminium, like this aluminum hardware after sealing, long-time use also not can because of since the aluminum plug owing to working life is reduced in the slit of a variety of causes formation.
Description of drawings
Fig. 1 is the structural representation of deep hole plug provided by the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the stereogram of deep hole plug provided by the present invention.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the invention provides a kind of deep hole plug, comprise aluminium plug end 1, this deep hole plug also comprises the second plug end 2 that welds together with aluminium plug 1 end.
The second plug end 2 can be a metal or alloy, and when the second plug end 2 was alloy, the second plug end 2 was Steel Alloy, titanium alloy or nickel alloy.When if the second plug end 2 is Steel Alloy, aluminium plug end 1 utilizes aluminium base solder to carry out soldering with Steel Alloy plug end, will be before welding to Steel Alloy plug end surfaces metal lining, and the metal of plating is copper, nickel, zinc, silver or aluminium coat.Aluminium plug end 1 also can adopt the transit joint pattern, and aluminium plug end 1 is soldered on the steel part of aluminizing, then the other end of copper brazing to steel.
Because the current potential difference can or can not produce galvanic corrosion in soldered joint, form the slit.Therefore, electrochemical corrosion owing to there is big difference in Electrode Potential, takes place in the soldering of aluminium plug end 1 and other metals easily, must add painting usually, and sealing compound or fluid-tight coating are to improve its anti-corrosion capacity.
The present invention is when concrete the making, and overall dimensions should be lower than face of weld 3mm, and plug should be positioned on the interior step of part.Hole internal clearance 0.05mm.
A level joint: crucial link and key structure be meant, because its inefficacy can cause operator or other staff's serious harm or cause serious operation consequence, radiographic examination.
