Description

The aircraft skin aging oven
Technology neck city
The present invention relates to a kind of thermal treatment unit, what relate in particular to a kind of aviation field carries out the specific equipment of ageing treatment to aircraft skin.
Background technology
At present, aircraft skin is all accomplished in common chassis or baking oven, because aircraft skin has the shape prolate, big, the lightweight characteristics of volume require HTFX to have the structure of rectangular parallelepiped, and temperature homogeneity is high, the characteristics that system homogeneity is high.And the fire door of a conventional oven adopts hinge type or electrodynamictype, when stove causes hinge break during at high temperature easily, or poorly sealed close, make the operator will constantly change consumable accessory.The furnace temperature thermal radiation of a conventional oven is higher, causes the stove surface temperature rise high, and a large amount of energy is by loss in vain.What the blower fan of a conventional oven adopted is one centrifugation blade, and temperature uniformity can't meet the demands.
Summary of the invention
The present invention will solve is that existing baking oven causes wasting energy because of furnace temperature is inhomogeneous when using, workpiece deformation, work-ing life short technical problem.Provide a kind of furnace temperature even, efficient energy-saving and product each item technical feature of producing satisfy the aircraft skin aging oven of the related request of AMS2750D, ZPS01700-00000E, BAC5621.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of aircraft skin aging oven, comprise body of heater, furnace lining, bell and heating system, the blower fan recycle system, interior bin, and said body of heater is a pit furnace, bell is arranged at the body of heater top; Said heating system is made up of heating unit, and heating unit divides the n layer to arrange from top to bottom along the furnace lining both sides, n >=2, and every layer heating unit is at least one; Heating unit in every layer is even setting, and the heating unit number on upper strata is less than the number of lower floor; The said blower fan recycle system comprises blower fan, air suction inlet and two convection current plates; Blower fan and air suction inlet are installed on the bell and can move away body of heater with bell; The blast inlet of blower fan is positioned at the bell top, and the impeller of blower fan, air suction inlet are positioned at the bell bottom, and said convection current plate is arranged at the both sides of air suction inlet respectively; And, be oppositely arranged perpendicular to body of heater inside; Bin is positioned at the centre of two convection current plates in said.
Fire door is arranged on the top of pit furnace body of heater; Help utilizing the self gravitation of bell to reach the effect that seals body of heater; Thereby avoided common stove to rupture, caused poorly sealed, problem such as need repairing, and be convenient to workpiece and get into burner hearth smoothly because of firedoor hinge; Changing the charging of car type furnace, loaded down with trivial details (car type furnace need be oven door opening; Could feed after chassis is left), and reduced locus shared when chassis is left, the heat that has produced when also having reduced chassis and body of heater poorly sealed leaks; With blower fan, air suction inlet and bell integral manufacturing, it can be moved with bell, help letting plug for outlet, convenient charging; In addition, because warm air is prone to the characteristic of rising, make the structure of heating unit storied placement; Make the interior bottom heat production of body of heater more than top; Help guaranteeing the even of whole body of heater internal temperature, thereby make heated parts ability thermally equivalent, reduced workpiece because of the uneven possibility that produces deformation of being heated.
For making things convenient for the charging discharging, also comprise furnace cover lifting mechanism, bell translation mechanism and system; Said furnace cover lifting mechanism comprises elevator and the lifting motor that is arranged on the bell below; Said bell translation mechanism comprises the guide wheel that is arranged on the bell top, the guide wheel motor of drive guide wheel rotation and the guide rail that is complementary, also can supplies guide wheel to slide with guide wheel; Said guide rail is independent of the pit furnace setting; And parallel with the symmetry axis direction on the bell width, be positioned at bell front side or rear side; Said system is to be connected with the electric control gear that temperature is surveyed appearance, triggering device, and it all is connected with furnace cover lifting mechanism, bell translation mechanism, moves with the control bell.Said system can adopt existing electric control gears such as computer, microcomputer, the process of opening, closing through the pre-set bell of PLC supervisor.This design can omnibearing lifting fire door, and shifts the side of fire door onto, increased the usage space before the fire door, and the furnace cover lifting translation is light laborsaving all through electric control gear control, need press the button to realize convenient and reliable operation automatically.In addition, broad ways translation bell can also shorten translation distance, cuts down the consumption of energy.
For strengthening the stability in the furnace cover lifting process; Said lifting motor has two; Lay respectively at the two ends of bell major axis or the two ends of minor axis, said lifting motor goes out spindle motor for two, and same lifting motor can drive two elevators and rotate synchronously; The transmission shaft that is equipped with shaft coupling through two ends between lifting motor and the elevator links to each other, and four elevators are evenly distributed on four jiaos of bell bottom.Four elevators are separately positioned on four jiaos of bells and run-in synchronism, make bell stressed evenly.
For adding high wind round-robin effect, make the interior temperature distribution of stove more even, said body of heater inner bottom part also is provided with plural I-shaped spare, and interior bin is placed on the I-shaped spare.One adopts joist steel I-shaped spare, on the unsettled joist steel that is placed in furnace bottom of work rest, is convenient to carry workpiece and is beneficial to hot air circulation.
As a kind of improvement project of the present invention, said watch box adopts knot that can be undone by a pull formula pressure strip structure to connect with furnace lining.This kind structure decrease the hot short circuit of steel member, and connect through bolt, be convenient to dismounting.
For further improving the homogeneity of temperature in the body of heater, said blower fan adopts major axis direct connection blower fan.This kind blower fan running is stable, and long service life, and can guarantee that temperature is even in the stove is that the product produced can satisfy SAT and the detection requirement of TUC among the AMS2750D.
For reducing the noise of wind in the air channel, said convection current plate employing is provided with the thin plate that draws muscle and processes, and employing activity link plate form is installed.Said one employing stainless steel sheet of thin plate that draws muscle that is provided with, thin plate helps noise reduction, draws the toughness that muscle helps strengthening thin plate, guarantees the durable of convection current plate; Described movable link plate formula is installed as prior art, refers to that promptly link plate is provided with hook, can hang over and form curtain wall on the column.This installing/dismounting that is beneficial in the use that is designed with.
As a kind of improvement project of the present invention, the bearing of said convection current plate also is provided with the link of at least one, and the link internal fixing has thermopair, and said thermopair is surveyed appearance with the temperature of system and linked to each other.After thermopair detects the interior temperature of coming out of the stove; Signal is conducted to system; So that the staff is the test macro homogeneity in the AMS2750D normative testing; To the adjustment of height, be that TUS will be more stable when being SAT, thereby the use properties of integral device is improved through the even performance of adjusted device temperature.
Advantage of the present invention is: save energy, can effectively prevent workpiece deformation, and temperature is even in the stove, the long service life of equipment.
