Abstract
The utility model discloses a lifting and moving device of a bell jar of a fork truck type ion-nitriding furnace, which comprises a lifting mechanism, a horizontal moving mechanism and a horizontal rail; the lifting mechanism is connected to the bottom of the bell jar of the fork truck type ion-nitriding furnace through a hinge; the horizontal moving mechanism moves in the horizontal rail; and the horizontal rail is fixed together with a base of the ion-nitriding furnace. According to the lifting and moving device of the bell jar of the fork truck type ion-nitriding furnace, disclosed by the utility model, the position of maximum stress is at the lower part of the bell jar, so that the center of gravity is low, and lifting is stable; and the horizontal track is welded together with the base of the ion-nitriding furnace, and the dead weight of the ion-nitriding furnace and larger area of the base can be utilized as a counterweight, so that the bell jar can be prevented from falling during horizontal movement.
Description
Technical field
The utility model relates to a kind of lifting and running gear, relates to specifically a kind of lifting and running gear of ion-nitriding furnace bell jar, belongs to Field of Heat-treatment.
Background technology
The ionitriding processing is that the workpiece that will want the nitriding processing places in the vacuum chamber of ion-nitriding furnace, and workpiece connects the negative pole of direct current glow discharge power supply, and bell jar connects positive pole.Under the DC electric field effect, furnace gas generation glow discharge, the surface of nitrogen (just) the ion bombardment workpiece (negative electrode) that generates, when workpiece being heated to needed nitriding treatment temp (generally between 400～600 ℃), activated nitrogen atom infiltrates the inside of workpiece, has improved hardness, wear resistance and the corrosion resisting property of workpiece surface.
The ion-nitriding furnace of general form all is to adopt the bell-jar structure mostly both at home and abroad at present, bell jar need to be raised with workpiece loading and unloading when ionitriding begins or finish.Consider that from security standpoint the bell jar that lifts preferably moves apart the top of stove, to guarantee operator's safety.The at present bell jar lifting/lowering of domestic and international most of bell-jar ion-nitriding furnaces and movement all is to rely on the driving in the workshop to lift, very inconvenience.In addition, the aspect ratio of bell-jar ion-nitriding furnace is higher, plant building with driving lifting bell jar needs that at least the height that is four times in stove is arranged, general plant building is difficult to meet this requirement, expect digging pit at mill floor in order to address this problem, ion-nitriding furnace is put into the hole, and the worktable of stove flushes with ground.The external ion-nitriding furnace of producing also has the bootstrapping of employing hoisting appliance at present, with hydraulic pressure or mechanically operated way bell jar is sling, and then with angle of bell jar rotation, makes bell jar depart from the base of ion-nitriding furnace.The external bell jar lifting/lowering device that adopts adopts high column structure mostly, and jack point rocks bell jar because center of gravity is higher, less stable at the top of bell jar like this in lifting process.In addition, can not topple over when rotated in order to guarantee bell jar, hoisting appliance must have larger base, and the rigidity of column root also will have higher requirement.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiency of above-mentioned prior art exactly, provides a kind of simple in structure, good stability and use lifting and the running gear of the ion-nitriding furnace bell jar of safety.
The utility model adopts following technical scheme:
A kind of lifting and running gear of fork-lift type ion-nitriding furnace bell jar, comprise hoisting appliance, horizontal mobile mechanism and horizontal rail, hoisting appliance links to each other by the bottom of hinge with the ion-nitriding furnace bell jar, horizontal mobile mechanism is mobile in horizontal rail, and the base of horizontal rail and ion-nitriding furnace is fixed together.
Further, between the top of bell jar and hoisting appliance, be provided with governing screw.
Further, the front wheel of horizontal mobile mechanism is positioned at the radial slit projected position of bell jar diameter maximum.
Further, hoisting appliance and horizontal mobile mechanism adopt hydraulic drive.
Further, hoisting appliance and horizontal mobile mechanism adopt mechanical transmission to drive.
The beneficial effects of the utility model are:
Lifting and the running gear of fork-lift type ion-nitriding furnace bell jar disclosed in the utility model have following several beneficial effects:
Since to the maximum weighted position of ion-nitriding furnace bell jar lifting below bell jar, center of gravity is low, lifting is steady.
2. the front wheel of horizontal mobile mechanism is positioned at the radial slit projected position of bell jar diameter maximum, and the ion-nitriding furnace bell jar is unlikely to the phenomenon that leans forward in lifting and moving process like this.
3. because this lifting and the horizontal rail of running gear and the base of ion-nitriding furnace are fixed together, can utilize the deadweight of ion-nitriding furnace and larger base area as equipoise, can guarantee that like this bell jar topples over moving horizontally Shi Buhui.
4. between the top of bell jar and hoisting appliance, be provided with governing screw, the verticality of regulating bell jar by governing screw, thus guarantee parallelism between bell jar and the chassis.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Below will lift and to describe in detail with moving process the ion-nitriding furnace bell jar: when needs are opened the bell jar 4 of ion-nitriding furnace, open first purging valve, inflate air in the vacuum chamber, after furnace pressure reaches a normal atmosphere, open lifting switch, rely on hydraulic pressure or mechanical transmission that bell jar is given rise to certain height, at this moment can close lifting switch, unlatching moves horizontally switch, relies on hydraulic pressure or mechanical transmission that the bell jar level is moved to certain position.For the sake of security, at this moment can open the decline switch, bell jar is fallen, bell jar is placed on the interim platform.When needs reset bell jar, can open lifting switch, then the height that the bell jar lifting is certain opens moving switch, and the bell jar level is moved to the top on stove chassis, then utilizes the gravity of bell jar self to fall bell jar and overlaps with the chassis.
The diameter of used ion-nitriding furnace vacuum bell jar is 1300 millimeters of φ in the present embodiment, highly is 1600 millimeters, heavily about 1.5 tons of bell jar.The lifting of bell jar and horizontal mobile mechanism all are to adopt hydrostatic transmission, the diameter of elevating ram is 40 millimeters of φ, length is 1500 millimeters, the diameter of Shift cylinder is 30 millimeters of φ, length is 1800 millimeters, adopt YBZ type hydraulic power unit, the gear oil pump duty is 1.2mL/r, and bell jar lifting speed is 1.5 m/mins; It is to utilize the gravity of bell jar self to descend that bell jar descends, and lowering speed is 1.3 m/mins.After bell jar gives rise to 1.6 meters height, open and move horizontally switch, bell jar moves with 2 m/mins velocity level.Bell jar can both keep speed even in whole lifting and moving process, and motion steadily.
