The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1～4.This vacuum sintering furnace coupling movable protective charging glove box main body is improved on the architecture basics of existing protection charging glove box.It comprises the casing 4 that is placed on the protection charging glove box on the horizontal locomotive 6 that shares with many sintering furnaces 1; be assembled in the slide valve formula glove box door 3 on the casing 4, be separately positioned on parts such as the slide valve formula sintering fire door 2 that docks with slide valve formula glove box door 3 on each sintering furnace 1 and control system.Wherein the structure of horizontal locomotive 6 is shown in Fig. 1～2; it is mobile at ground rail 5 to drive horizontal locomotive 6; in order to allow the casing 4 of placing the protection charging glove box on the horizontal locomotive 6 dock with the sintering furnace 1 of diverse location, for the sintering furnace 1 on the diverse location is realized charging.Yard material in the casing 4 waits operating process, can carry out in the fixed position, and this brings very large benefit for the management that the stability that guarantees the operations such as sign indicating number material in the casing 4 reaches the scene.
Docking site between the slide valve formula sintering fire door 2 of the slide valve formula glove box door 3 of being with chamber door plate 14 and band stove door plant 15, fire door abutted flange 12, the chamber door abutted flange 13 of symmetrical configuration are set, and slide valve formula glove box door 3 and slide valve formula sintering fire door 2 can be linked together dock locking device 10.Between on glove box door 3 and the sintering fire door 2; utilize the vertical driving and reversing mechanism 9 of casing on the casing 4; with chamber door abutted flange 13 with fixedly have the fire door abutted flange 12 of O-ring seal to compress mutually; be linked together by butt joint locking device 10 again, between the slide valve formula glove box door 3 of docking and slide valve formula sintering fire door 2, form firm airtight guard space.
Slide valve formula glove box door 3 is with after slide valve formula sintering fire door 2 docks, start the chamber door abutted flange 13 that the vertical driving and reversing mechanism 9 of casing promotes on the casing 4 earlier, near the fire door abutted flange 12 on the sintering fire door 2, compress the sealing ring on the fire door abutted flange 12, recycling butt joint locking device 10 is connected and fixed slide valve formula glove box door 3 and slide valve formula sintering fire door 2 together.After having formed the airtight guard space that separates with atmosphere between the Liang Men; charge into protective gas by loading line 11; the air in the airtight guard space is fallen in displacement; then chamber door plate 14, stove door plant 15 are opened, guaranteed that casing 4 inner chambers are communicated with in being full of the atmosphere of protective gas with sintering furnace 1 inner chamber.After said structure had been realized slide valve formula glove box door 3 and slide valve formula sintering fire door 2 is docked, the effect of air in the airtight guard space was fallen in displacement fully, thereby avoids air to enter sintering furnace 1 inner chamber effectively, has improved the sintering crudy.
In casing 4, be provided with the material fork driving and reversing mechanism that is driven by hydraulic motor 17 and the material fork elevating mechanism that is driven by telescopic hydraulic cylinder 20.
Material fork driving and reversing mechanism: comprise hydraulic motor 17, hydraulic motor 17 drives utilizes bearing to be assembled in ball-screw 18 on the built-in riser guide frame 16, the material fork roller on the swivel nut that is fixed on material fork 8 bottoms that is meshed with ball-screw 18 and the guide rail that is slidably supported on built-in riser guide frame 16.Hydraulic motor 17 drives ball-screw 18 rotations, drive is fixed on swivel nut the moving axially along ball-screw 18 of material fork 8 bottoms, the roller that drives material fork 8 rolls at the guide rail of built-in riser guide frame 16, stretch out outside the casing 4, with furnace charge 7(workpiece) deliver to the relevant position with sintering furnace 1 inner chamber of casing 4 inner chamber UNICOMs.The advance and retreat of material fork 8 move and adopt ball-screw 18 and swivel nut as transmission mechanism, and by fluid motor-driven, this operates steadily material fork 8, and speed-controllable can be parked in the optional position during charging, thereby realizes charging several times.The employing pneumatic actuation that in the past had, the employing mechanical chain transmission that has, pneumatic gearing starting point, terminal point have impact, the chain transmission is in service to have string to move phenomenon, this all is very large harm concerning the powdered metallurgical material of wanting sintering, can cause the damage of dropping of device corner, the material fork 8 of pneumatic promotion can not be parked in the optional position, can't accomplish to feed several times.Material is pitched 8 advance and retreat owing to adopt telescopic hydraulic cylinder 20 to drive, and does not adopt motor-driven, so eliminated the influence of metallic dust to motor, improves reliability of operation.The transmission mechanism that is meshed with the swivel nut that is fixed on material fork 8 bottoms with ball-screw 18 promotes material fork 8 advance and retreat, has motion equally steadily, and impact is little, the advantage that controllability is good.
Material fork elevating mechanism: comprise telescopic hydraulic cylinder 20; be fixed on the directive slide track 22 of casing 4 bottoms of protection charging glove box; the interlock pan carriage 21 that moves along directive slide track 22 length directions that telescopic hydraulic cylinder 20 drives, the four connecting rod link gears that are hinged and constitute by interlock pan carriage 21, support link 19 and built-in riser guide frame 16.In four connecting rod link gears of material fork elevating mechanism, support link 19 upper ends and built-in riser guide frame 16 are hinged, and the interlock pan carriage 21 that support link 19 lower ends and telescopic hydraulic cylinder 20 drive is hinged; Support link 19 lower ends are under the interlock pan carriage 21 that telescopic hydraulic cylinder 20 drives drives; directive slide track 22 length directions along casing 4 bottoms that are fixed on protection charging glove box move, and make with the hinged built-in riser guide frame 16 in support link 19 upper ends to carry out elevating movement synchronously.The lifting of this mechanism is steady, and lifting distance is big, and can stop at arbitrary height reposefully, and these characteristics have improved reliability and the stationarity of equipment, and the convenience of the operation of operating personnel's both hands in glove box, has reduced working strength.Overcome air lifter in the past and can only stop at upper and lower two positions, the shortcoming of lifting process poor stability.
The bottom group of casing 4 is contained on the carrying roller of horizontal locomotive 6; the hydraulic cylinder two ends of the vertical driving and reversing mechanism 9 of casing are hinged on horizontal locomotive 6 respectively and stop on 4 with the case of protection charging glove box; stretch out the piston of hydraulic cylinder; can make case stop 4 with horizontal locomotive 6 between produce and vertically move; promote the fire door abutted flange 12 on the chamber door abutted flange 13 close slide valve formula sintering fire doors 2 on the casing 4; compress the sealing ring on the fire door abutted flange 12; connect butt joint locking device 10 again, slide valve formula glove box door 3 and slide valve formula sintering fire door 2 are linked together securely.Otherwise; dismantle butt joint locking device 10; the hydraulic cylinder piston of the vertical driving and reversing mechanism 9 of withdrawal casing; chamber door abutted flange 13 on the pulling casing 4 leaves the fire door abutted flange 12 on the slide valve formula sintering fire door 2; drive horizontal locomotive 6, can make the case of protection charging glove box stop 4 and move to the docking location of next sintering furnace 1 at ground rail 5.
