Description
The bent axle that the utility model relates to a kind of underslung crankshaft Equipment for Heating Processing hangs conveying and channel seal device.
The isometric rod workpieces of bent axle in heat treatment process, requires it to be heated or cools off evenly, and security deposit's phase constitution changes fully, and requires axial deflection little.Bent axle thermal treatment is at present all carried out in chamber furnace, and the workpiece horizontal reactor is placed in the stove, be heated to technological temperature after, artificial hook goes out, and carries out water smoke spray and blowing cooling at the cooling station of simple and easy worn-out open type.Therefore heating of bent axle upper and lower surface or cooling temperature are inconsistent, thermal treatment quality can not guarantee, the hardness scattered error is big, and mechanical property can not reach the high trade mark, and the geometrical dimension distortion is big, also to carry out alignment process after the thermal treatment, increase human and material resources, simultaneously, this mode of production is little in batches, labour intensity is big, work under bad environment.
For solving a series of problems that the horizontally-arranged thermal treatment of the isometric rod workpieces of bent axle brings, the utility model provides bent axle to hang and has placed, bent axle hangs to be placed and spinning and channel seal device thereof, it is to adopt the suspension type conveyor chain, and the suspender that is applicable to the vertical placement of workpiece is housed on conveyor chain.Tightness system places stretched wire passage both sides sealing passage on the furnace roof, prevents that hot gas from overflowing.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Below in conjunction with accompanying drawing 1,2 its detailed structure of explanation and working conditions.
1, bent axle transfer unit
As shown in Figure 1, the bent axle transfer unit is made up of piling conveyor chain 1, channel-section steel 2, the thrust bearing 3 of usheing to seat, suspension rod 4, gear 5, transmission mechanism 6, bracketplant 7, clamp 8.Piling conveyor chain 1 is the suite of equipment of being produced by specialized factory, channel-section steel 2 and conveyor chain 1 Bolt Connection.Suspension rod 4 is made by high temperature steel, gear 5 casting post-treatment moulding, bracketplant 7 is by the high temperature steel casting, and clamp 8 is by high temperature steel processing welding fabrication, and suspension rod 4 passes the circular hole of bracketplant 7 during installation, fix with pin, pass the circular hole of cover plate 9 again, link with thrust bearing 3, thrust bearing is installed on the channel-section steel 2 with bolt, gear 5 is used key connecting with suspension rod 4, and bent axle vertically hangs on the clamp 8.The transmission mechanism of being made up of motor, step-down gear, gear 6, the frame that is fixed on shaped steel weldering system with Bolt Connection be in last, and solid welding is calmly mutually for this shelf and furnace binding.When conveyor chain 1 drove suspension rod 4 and runs to gear place station on the transmission mechanism, gear 5 and toothing drove suspension rod 4 and crankshaft rotation.In sum, the indignant suspension rod of stating to having gear 4, pass the circular hole of cover plate 9, the below penetrates in the circular hole of the bracketplant 7 that has clamp 8 and with pin again and fixes, its top links with thrust bearing 3, thrust bearing 3 usefulness bolts are installed on the channel-section steel 2, and channel-section steel 2 and conveyor chain 1 Bolt Connection constitute the bent axle transfer unit.
2, channel seal parts:
As shown in Figure 2, these parts are by cover plate 9, pull bar 10, cover plate bracing frame 11, cooling water tank 12, and bellows 13 are formed.Cover plate 9 high temperature steel casting, for guaranteeing sealing effectiveness, cover plate 9 overlaps when installing mutually, lies on the cover plate bracing frame 11.The pull bar of making by heat-resisting round steel 10, one end and cover plate 9 welding, one end and channel-section steel 2 thread connection, guarantee when suspension rod 4 drives crankshaft rotation, cover plate 9 does not rotate, and makes cover plate 9 hide the furnace roof passage and prevents that hot gas from overflowing, and cover plate bracing frame 11 is made by heat-resisting round steel, be welded in the upper surface of cooling water tank 12, cover plate 9 slides on cover plate bracing frame 11.The purpose that adopts cooling water tank 12 is in order to reduce the use temperature of cover plate 9, to prolong the work-ing life of cover plate 9.Because cover plate 9 is that line contacts with cover plate bracing frame 11, the friction resistance when having reduced cover plate 9 operations.Cooling water tank 12 usefulness steel plates are welded into, and are installed in furnace roof passage both sides with the shaped steel supporting, and bellows device 13 is made up of the casing and the blower fan of welded steel plate.Casing weldering can be made rectangle as required or other is adapted at the shape that install top, passage both sides.One side is a blow box, and a side is an air-suction trunk, in the middle part or the appropriate location of blow box gas blower is housed, and is having the blowing mouth identical with passage length near passage one side.At air-suction trunk middle part or suitable position induced draft fan is housed, having with the air suction inlet of blowing mouth near channel side with length, blowing mouth and air suction inlet all are higher than cover plate 9, the air that blow box is bloated causes in the air-suction trunk discharges.The bellows device is installed on the furnace roof of being made up of steel plate, shaped steel and refractory materials 14.The air that the bellows device blows out plays the effect of air curtain, further barrier the hot gas that overflows of furnace roof.Be exactly on install side, furnace roof 14 passage both sides, to be welded with cover plate to prop up the cooling water tank 12 that connects frame 11 in short, on the cover plate bracing frame, put the cover plate 9 that is welded with pull bar 10 and overlaps mutually, the other end of pull bar and channel-section steel 2 thread connection are installed the bellows device of being made up of blow box, air-suction trunk, gas blower, induced draft fan 13 and are constituted the channel seal parts above furnace roof passage both sides.
Bent axle transfer unit, channel seal parts connect by suspension rod, thrust bearing, cover plate, pull bar, channel-section steel and form bent axle suspension type thermal treatment conveying and channel seal device.
In sum, its work is to realize like this, when Equipment for Heating Processing is worked, 1 operation of piling conveyor chain, under the control of PLC sequence controller, the bent axle transfer unit that bent axle is arranged by productive temp piling conveyor chain dynamic load is to next station operation, when the bent axle transfer unit runs to transmission mechanism 6 place stations, in the time of need doing the spinning operation, the toothing in gear 5 and the transmission mechanism 6 is controlled by the PLC sequence controller, start transmission mechanism 6, driven gear 5 together rotates suspension rod 4, drives bent axle and rotates simultaneously.
Can have on the furnace roof with the passage of body of heater, and the sealing of passage be realized by the channel seal parts to next station operation for making the bent axle sprung parts with length.At first cover plate 9 covers the porthole, be shelved on the cover plate bracing frame 11, because bent axle transfer unit suspension rod 4 passes cover plate 9 and links by pull bar 10 and crank channel sealing element, therefore, when the bent axle transfer unit moves, cover plate 9 together moves, on cover plate bracing frame 11, slide, effectively having covered the interior a large amount of high-temperature furnace gas of stove outwards overflows, and further sealed the hot gas that overflows from cover plate 9 slits by the air curtain of bellows device ejection, thereby reached all sidedly sealing effectiveness effectively, making throat temperature only is about 70 ℃, meets the requirement of national relevant industrial stove throat temperature.
This device is widely used in bent axle and stock class workpiece hangs in the heat-treatment production line of placing and Equipment for Heating Processing.
