Abstract
The utility model relates to a heat treatment device, in particular to a large-sized vertical vacuum furnace which comprises a furnace stand, a furnace body and a vacuum pump. The large-sized vertical vacuum furnace is characterized in that the bottom of the furnace body is provided with a round hole, and the lower portion of the furnace body is provided with a hydraulic feed-discharge device corresponding to the round hole. The hydraulic feed-discharge device comprises a hydraulic cylinder, a push rod, a tray disposed at the top of the push rod and guide posts for guiding use. The hydraulic cylinder is connected with the push rod. The guide posts are disposed at the edge of the tray disposed at the top of the push rod, and the top of the tray is provided with an insulation seal layer. Feeding and discharging are automatically operated by the hydraulic cylinder, the action is stable, response speed is high, and operating efficiency is high. The lifting problem of workpieces subjected to heat treatment is solved, and potential safety hazards of slipping of the workpieces in lifting are avoided.
Description
Technical field
The utility model relates to a kind of equipment for Heating Processing, relates in particular to a kind of large-scale vertical vacuum oven.
Background technology
Vacuum heat treatment is the complex art that two specialties of vacuum technique and thermal treatment combine, and refers to metallic article in vacuum or vacuumize first to lead to afterwards under the inert gas conditions heat, then the technology of quench cooled in oil or gas.Vacuum heat treatment furnace is the equipment that workpiece is heat-treated under vacuum condition, and vacuum heat treatment almost can realize whole thermal treatment process, such as quenching, annealing, tempering, carburizing, nitrogenize etc.; Vacuum heat treatment and other prior heat treatment methods are compared, and have advantages of that some are unique: cleaning action, vacuum protection effect, outgassing, fat abstraction, the saving energy.
Present large-scale vertical vacuum furnace all is the mode that adopts from the top input and output material: open bell, the material of need being heat-treated with suspender hangs in the stove, material is hung out after the thermal treatment again.There is following shortcoming in this input and output material mode: (1) bell is heavy, opens to be not easy, and after thermal treatment is finished, material be hung out difficulty; (2) material is hung in the special suspender of needs, and material is dangerous in the process of handling, exists the material landing body of heater and operator to be caused the possibility of potential safety hazard; (3) for the special material of some shape, be not easy to lifting and fixing.
The utility model content
The utility model is for the problems referred to above, provides a kind of input and output material convenient, simple to operate large-scale vertical vacuum oven.
The technical solution adopted in the utility model is as follows: the large-scale vertical vacuum oven, comprise grate, be arranged at body of heater on the described grate, be used for vacuum pump that described body of heater is vacuumized, it is characterized in that: be provided with a circular hole in the bottom of described body of heater, be provided with a hydraulic pressure charging/discharging device corresponding with circular hole in the bottom of described body of heater.
Described hydraulic pressure charging/discharging device comprises hydraulic ram, push rod, is installed in the pallet at push rod top, the guidepost that is used for leading, described hydraulic ram links to each other with push rod, the push rod top is equipped with a pallet, and described tray edge is provided with guidepost, and tray top is provided with the thermal-insulating sealing layer.
The utility model compared with prior art, have the following advantages: (1) the utility model is provided with a hydraulic pressure charging/discharging device corresponding with circular hole at bottom of furnace body, when the needs charging, the push rod of hydraulic ram is return downwards, so the workpiece that need can be heat-treated is placed on the pallet at push rod top, the hydraulic ram action, push rod upwards rises, and advances vacuum oven to carry out workpiece, and thermal treatment is complete, push rod is return downwards, and workpiece is come out of the stove.This input and output material mode all can be controlled hydraulic ram automatic operation, stable action, fast response time, high efficiency.(2) the utility model does not need suspender handling workpiece, has both solved the lifting difficult problem of workpiece after the thermal treatment, the potential safety hazard of workpiece landing when yet not having handling.
Description of drawings
Figure l is structural representation of the present utility model.
In the accompanying drawing, 1-grate, 2-vacuum pump, 3-body of heater, 4-thermal-insulating sealing layer, 5-pallet, 6-guidepost, 7-push rod, 8-hydraulic ram.
Embodiment
As scheme shown in the l, a kind of large-scale vertical vacuum oven comprises grate 1, is arranged at body of heater 3 on the described grate 1, is used for vacuum pump 2 that described body of heater 3 is vacuumized, it is characterized in that: be provided with a circular hole in the bottom of described body of heater 3, as the outlet of input and output material.Be provided with a hydraulic pressure charging/discharging device corresponding with circular hole in the bottom of described body of heater 3, be used for workpiece to be heated being sent in the stove and in stove, being taken out the complete workpiece of thermal treatment.
Described hydraulic pressure charging/discharging device comprises hydraulic ram 8, push rod 7, is installed in the pallet 5 at push rod 7 tops, the guidepost 6 that is used for leading, described hydraulic ram 8 links to each other with push rod 7, push rod 7 tops are equipped with a pallet 5, described pallet 5 edges are provided with guidepost 6, and pallet 5 tops are provided with thermal-insulating sealing layer 4.Guidepost 6 is used for guaranteeing the direction of motion of hydraulic ram 8, push rod 7, pallet 5 motions, guarantees workpiece held stationary in rising and decline process.Described pallet 5 tops are provided with thermal-insulating sealing layer 4, thereby guarantee that vacuum oven vacuumizes Shi Buhui gas leakage, guarantees that the heat of heating can not leak.
Input and output material process of the present utility model is as follows: be provided with a hydraulic pressure charging/discharging device corresponding with circular hole in body of heater 3 bottoms, when the needs charging, hydraulic ram 8 actions, push rod 7 is return downwards, so the workpiece that need can be heat-treated is placed on the pallet 5 at push rod 7 tops, hydraulic ram 8 actions, push rod 7 upwards rises, and advances vacuum oven to carry out workpiece, and thermal treatment is complete, push rod 7 is return downwards, and workpiece is come out of the stove.
This input and output material mode all can be controlled hydraulic ram 8 automatic operations, stable action, fast response time, high efficiency.Do not need suspender handling workpiece, both solved in the stove lifting difficult problem of workpiece after the thermal treatment, the potential safety hazard of workpiece landing when yet not having handling.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and design thereof, all should be encompassed within the protection domain of the present utility model.
