Below in conjunction with accompanying drawing and preferred embodiment the utility model is described in more detail.
As shown in Figure 1, according to an embodiment of the present utility model, automatic control furnace for vacuum heat treatment mainly comprise body of heater 1, near the vacuum heating chamber 2 in the back fire door, along the material carriage direction in the vacuum heating chamber upstream and can be its feeding vacuum heat treatment chamber 3, be arranged on the heat insulation door 4 between vacuum heat treatment chamber 2 and the vacuum heating chamber 3 and be placed in control device 5 outside the stove, wherein, body of heater 1 is horizontal cylindrical structure, one end is a back fire door 6, and the other end is preceding fire door.
In the vacuum heating chamber 2 a plurality of thermal treatment temp sections can be arranged, its temperature can be regulated in the scope between room temperature～2500 ℃.In addition, be provided with a plurality of sieges 8,9,10 that need heat treated metallic substance and be set up in parallel that are used to load in the vacuum heating chamber 2, be positioned over the charging basket 19 on the siege, be used to transport the e Foerderanlage 11 of charging basket 19, and adorn the temperature-detecting device 20 in the sub-stove.
Temperature-detecting device 20 can detect vacuum heating chamber 2 temperature inside and feed back to the outer Controlling System of stove.This temperature inspection device for catching 20 comprises a Temperature Measure Control assembly, can be each siege and sets a temperature section, and a plurality of Temperature Measure Control steps can be set in the different temperature sections.In the present embodiment, the maximum quantity of material group of processing differing temps section are three.
Below siege 8,9,10, all there is one to be used to control the rising of siege and the jacking system 13,14,15 of decline process respectively.
Be provided with thermal treatment platform 12, e Foerderanlage 11 and jacking system 18 and transfer system 16 etc. in the vacuum heat treatment chamber 3, wherein, e Foerderanlage 11 is installed on the guide rail on the thermal treatment platform 12; Transfer system 16 is connected with e Foerderanlage 11, and the left and right horizontal that is used to control e Foerderanlage 11 moves; Jacking system 18 is installed in thermal treatment platform 12 belows, is used to control the vertical movement up and down of thermal treatment platform 12 and e Foerderanlage 11.
Heat insulation door 4 also is furnished with lifting device 17.
In addition, stove is useful on control outward and regulates each PLC Controlling System 5 of moving in the stove.This control device 5 receive survey the temperature information that device 20 detects and feed back to by the temperature bolt after, the thermal treatment temp in the controllable adjustable vacuum heating chamber 2.On the other hand, it is temperature required that PLC control device 5 can be set each siege, and can change at any time.In addition, the lifting device 17 of the horizontal transfer system 16 of the road system 18 that rises of the jacking system under the siege 13,14,15, thermal treatment platform 12 and e Foerderanlage 11 and heat insulation door is also all by described PLC Controlling System 5 controls.
The motion of siege has following several mode: can distinguish self-movement, also can two interlock, a plurality of interlocks etc.These mode of motion all control by the PLC controller that a plurality of sieges carry out synchronously or asynchronous movement and realizing.
In a preferred embodiment of the present utility model, three sieges 8,9,10 are arranged in the vacuum heating chamber 2 of automatic control furnace for vacuum heat treatment, mode of motion and charging method are selected by the workpiece size cases, and the concrete operations principle is as follows:
Needs are contained in carry out the shove charge simultaneously of heat treated material on the siege 8,9,10, and come out of the stove by the order of siege 8,9,10.If the situation of interlock is arranged, interlock siege group is carried same charging basket, and moves simultaneously as a siege, and this moment is near the linkage groups elder generation discharging of heat insulation door 4 one ends, near discharging behind the siege of back fire door 6 one ends.
Mode 1: siege 8,9 interlocks, siege 10 is independent.This kind mode has been applicable to a small amount of high temperature (as 1200 ℃) heat treatment material, under the situation of a large amount of low temperature (as 800 ℃) heat treatment materials.At this moment, be put into siege 10 in the future, prepare to take out at last with small powder basket dress high temperature material workpiece; Be placed on a big charging basket dress low temperature material workpiece on the common plane of siege 8,9 and prepare to take out earlier.
Mode 2: siege 8 is independent, siege 9,10 interlocks.This kind mode is applicable to the situation that the ratio of wanting heat treated material and mode 1 are opposite, promptly more than the high-temperature heat treatment material and the low-temperature heat treatment material after a little while.Under this mode of operation, big charging basket dress high temperature material workpiece is placed on prepares the back taking-up on the siege 9,10, and small powder basket dress low temperature material workpiece is placed on to be prepared on the siege 8 to take out at first.
Mode 3:3 siege motion is independent respectively.This kind mode is applicable to wants the wide in variety of heat treated material, under the less situation of part.The material of same thermal treatment temp will be put department's one charging basket, and the low order of the temperature of siege 8 is placed on the siege according to the temperature height of siege 10 then.
Mode 4: have only a kind of and the measure-alike or approaching part of this stove maximum functional, with a big charging basket charging.At this moment, 3 siege interlocks.
In a further advantageous embodiment, 3 port bed motions are independent respectively.At this moment, the heat treated workflow of vacuum oven is as follows:
At first press the workpiece situation and select charging and siege mode of motion, the charging basket 19 and being put on the e Foerderanlage 11 of then material being packed into, heat insulation door 4 in the middle of opening subsequently moves right e Foerderanlage 11, and species are sent into vacuum heating chamber 2.At this moment, all siege rises, and gets material from e Foerderanlage 11.Get the material finish after, e Foerderanlage 11 withdraws from heating chamber 2 to left movement.Then, heat insulation door 4 in the middle of closing, all siege descends, heating chamber 2 beginning heat temperature raisings.
When vacuum heating chamber 2 reached the temperature of low-temperature heat treatment material and insulation finishes on request, heating chamber 2 stopped heating, and siege rises then, middle heat insulation door 4 is opened, then e Foerderanlage 11 moves right, and stops until siege 8, takes off the low-temperature heat treatment material on the siege 8 subsequently.E Foerderanlage 11 is transported to thermal chamber 3 to left movement with the low-temperature heat treatment material, and last middle heat insulation door 4 is closed.
At this moment, 3 pairs of low temperature material of thermal chamber are handled, and vacuum heating chamber 2 continues to heat up.The temperature that metallic substance on reaching siege 9 is required also is incubated when finishing on request, the temperature of warm processing material also is incubated when finishing on request in promptly reaching, e Foerderanlage 11 is warm processing material from siege 9 takes out, and sends into adjacent thermal chamber 3 and handles.
Equally, heating chamber 2 continue to be warming up to be jealous of the metallic substance of bed on 10 to handle required temperature after, e Foerderanlage 11 is sent the metallic substance that loads into vacuum heat treatment chamber 3 and is handled.
Above workflow is controlled by the PLC Controlling System.
Above workflow control also comprises temperature rise rate control and furnace temperature curve controlled.
In an embodiment of the present utility model, this vacuum oven mainly is applicable to quenching.
Above disclosed only is preferred embodiment of the present utility model, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
