Description
Technical field
The present invention relates to a kind of lifting and mobile device, more particularly to lifting and the mobile device of a kind of ion-nitriding furnace bell jar, belong to Field of Heat-treatment。
Background technology
It is that the workpiece being intended to Nitrizing Treatment is placed in the vacuum chamber of ion-nitriding furnace that glow discharge nitriding processes, and workpiece connects the negative pole of direct current glow discharge power supply, and bell jar connects positive pole。Under DC electric field effect, furnace gas generation glow discharge, the surface of nitrogen (just) the ion bom bardment workpiece (negative electrode) generated, while by workpiece heat to required Nitrizing Treatment temperature (being typically between 400～600 DEG C), activated nitrogen atom penetrates into the inside of workpiece, improves the hardness of surface of the work, wearability and corrosion resisting property。
The ion-nitriding furnace of general-purpose type is all adopt bell-jar structure mostly both at home and abroad at present, needs when glow discharge nitriding starts or terminates to raise with workpiece loading and unloading bell jar。From safety considerations, the bell jar lifted preferably moves apart the top of stove, to ensure the safety of operator。Bell jar lifting/lowering and the mobile driving being all dependent in workshop of current domestic and international most of bell-jar ion-nitriding furnaces lift, extremely inconvenience。Additionally, the aspect ratio of bell-jar ion-nitriding furnace is higher, the height being four times in stove is at least needed with the plant building of driving lifting bell jar, general plant building is difficult to meet this requirement, expect digging pit on mill floor to solve this problem, ion-nitriding furnace is put into hole, and the workbench of stove flushes with ground。The external ion-nitriding furnace produced also has employing bootstrapping elevating mechanism at present, is sling by bell jar by hydraulic pressure or mechanically operated way, then bell jar is rotated an angle, makes the base of bell jar deviation ion-nitriding furnace。The external bell jar lifting/lowering device adopted adopts high column structure mostly, and jack point, at the top of bell jar, so makes bell jar rock in lifting process, less stable because center of gravity is higher。It addition, in order to ensure that bell jar will not be toppled over when rotated, elevating mechanism must have bigger base, the rigidity of column root also to have higher requirement。
Summary of the invention
The technical problem to be solved, it is simply that overcome the deficiency of above-mentioned prior art, it is provided that a kind of simple in construction, good stability and use the lifting of safe ion-nitriding furnace bell jar and mobile device。
The present invention adopts the following technical scheme that
The lifting of a kind of fork-lift type ion-nitriding furnace bell jar and mobile device, including elevating mechanism, horizontal mobile mechanism and horizontal rail, elevating mechanism is connected with the bottom of ion-nitriding furnace bell jar by hinge, horizontal mobile mechanism moves in horizontal rail, and the base of horizontal rail and ion-nitriding furnace is fixed together。
Further, between the top of bell jar and elevating mechanism, it is provided with set screw。
Further, the front wheel of horizontal mobile mechanism is positioned at the RADIAL projected position of bell jar diameter maximum。
Further, elevating mechanism and horizontal mobile mechanism adopt hydraulic-driven。
Further, elevating mechanism and horizontal mobile mechanism adopt machine driving to drive。
The invention has the beneficial effects as follows:
The lifting of fork-lift type ion-nitriding furnace bell jar disclosed in this invention and mobile device, have following items beneficial effect:
1. the maximum weighted position owing to ion-nitriding furnace bell jar being lifted is the lower section at bell jar, and center of gravity is low, and lifting is steadily。
2. the front wheel of horizontal mobile mechanism is positioned at the RADIAL projected position of bell jar diameter maximum, and such ion-nitriding furnace bell jar is unlikely to, in lifting and moving process, the phenomenon that leans forward。
3. owing to this lifting and the mobile horizontal rail of device are fixed together with the base of ion-nitriding furnace, it is possible to use the deadweight of ion-nitriding furnace and relatively larger base area, as counterbalance, so can ensure that bell jar will not be toppled over when moving horizontally。
4. between the top of bell jar and elevating mechanism, it is provided with set screw, is regulated the perpendicularity of bell jar by set screw, thus the depth of parallelism ensured between bell jar and chassis。

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
Embodiment 1, as shown in Figure 1-2, the invention discloses the lifting of a kind of fork-lift type ion-nitriding furnace bell jar and mobile device, including elevating mechanism 1, horizontal mobile mechanism 2 and horizontal rail 6, elevating mechanism 1 is connected with the bottom of ion-nitriding furnace bell jar 4 by hinge 3, horizontal mobile mechanism 2 is mobile in horizontal rail 6, and the base 7 of horizontal rail 6 and ion-nitriding furnace is fixed together。The chassis 8 of ion-nitriding furnace is fixed on base 7, and under in working order, ion-nitriding furnace bell jar 4 and chassis 8 are combined, O-ring seal seal, be evacuated in stove。Set screw 5 it is provided with, for regulating the perpendicularity of bell jar 4, to ensure the depth of parallelism between bell jar 4 and chassis 8 between the top of bell jar 4 and elevating mechanism 1。The front wheel 9 of horizontal mobile mechanism 2 is positioned at the RADIAL projected position of bell jar 4 diameter maximum, and bell jar so can be made to be not susceptible to lean forward in motor process。
Below will to ion-nitriding furnace bell jar lift will and moving process describe in detail: when need open ion-nitriding furnace bell jar 4 time, first open vent valve, inflate air in vacuum chamber, reach after an atmospheric pressure until furnace pressure, open lifting switch, rely on hydraulic pressure or machine driving that bell jar gives rise to certain height, at this moment can close lifting switch, unlatching moves horizontally switch, relies on hydraulic pressure or machine driving that bell jar level is moved to certain position。For the sake of security, at this moment can open decline switch, make bell jar fall, bell jar is placed on an interim platform。When bell jar is resetted by needs, it is possible to open lifting switch, bell jar is lifted certain height, then opens moving switch, bell jar level is moved to the top on stove chassis, then utilize the gravity of bell jar self fall bell jar and overlap with chassis。
The diameter of ion-nitriding furnace vacuum bell jar used in the present embodiment is φ 1300 millimeters, is highly 1600 millimeters, and bell jar weighs about 1.5 tons。The lifting of bell jar and horizontal mobile mechanism are all adopt hydraulic drive, the diameter of elevating ram is φ 40 millimeters, length is 1500 millimeters, the diameter of Shift cylinder is φ 30 millimeters, length is 1800 millimeters, adopting YBZ type hydraulic power unit, gear oil pump delivery is 1.2mL/r, and bell jar lifting speed is 1.5 ms/min；It is that the gravity utilizing bell jar self declines that bell jar declines, and decrease speed is 1.3 ms/min。After bell jar gives rise to 1.6 meters of height, opening and move horizontally switch, bell jar moves horizontally with the speed of 2 ms/min。Bell jar can keep speed uniform in whole lifting and moving process, stable movement。
