Automatic continuous vacuum oven working process is: manually by transmission car, workpiece charging basket is delivered to feeding car, working conditions reaches laggard bin gate 21 and automatically opens, feeding car upper roller transmission system and preparation feed chamber roller transmission system 27 start and automatically workpiece charging basket are sent into preparation feed chamber simultaneously, charging basket arrives preparation feed chamber arrests laggard truck upper roller transmission system and preparation feed chamber roller transmission system 27 stops simultaneously, and feeding gate 21 is closed automatically.Preparation feed chamber starts to be evacuated to below 0.4Pa, once detecting vacuum heating chamber automatically, system do not have after charging basket, in the middle of first, gate is opened automatically, preparation feed chamber roller transmission system and vacuum heating chamber roller transmission system are automatically sent into workpiece heating chamber and are heated to 450 ℃, be incubated 1 hour, maintain vacuum tightness and be not less than 0.005Pa, after once the automatic detection of system cooling room does not have charging basket and vacuum condition to reach, in the middle of second, gate is opened automatically, heating chamber roller transmission system and cooling room roller transmission system 28 are sent charging basket into cooling room automatically, charging basket arrives after cooling room closed position, in the middle of second, gate is closed automatically, system is automatically filled with high pure nitrogen and starts air-cooled circulating cooling system, within cooling 45 minutes, make workpiece surface temperature drop to below 80 ℃, after discharging condition reaches, system is automatically controlled cooling room discharge door 26 and is opened the door, cooling room transmission system 28 is automatically released charging basket cooling room and also automatically close cooling room discharge door 26 to discharging car, cooling room is evacuated to below 0.4Pa, wait for the supplied materials of heating chamber, artificial blanking, start next circulation.Automatic continuous vacuum oven adopts the processed continuously mode in three Room (preparation feed chamber, vacuum heating chamber, cooling room), heating chamber is always under high temperature, high vacuum state, avoid outside contamination, saved that vacuum heating chamber vacuumizes repeatedly, heating and cooling and cooling time repeatedly simultaneously, greatly improve production efficiency, guaranteed the needs of batch production.Automatic continuous vacuum oven has been installed the roller transmission rig for transmission charging basket in each vacuum chamber, by roller, is rotated with charging basket lower plane and is produced frictional force, impels charging basket to move forward.Each vacuum chamber roller transmission rig uses independent driving reducing motor, and according to the different online position detecting mechanism of the different uses of use temperature, the online position detecting mechanism that wherein heating chamber is used will be faced the strict accurately location in high temperature, high vacuum seal and charging basket position, and spy has designed and developed the online position detecting mechanism of a kind of automatic continuous vacuum oven.The working process of this position detecting mechanism in vacuum heating chamber is as follows: charging basket is by preparing feed chamber roller transmission system from preparing feed chamber to vacuum heating chamber course of conveying, the T shape test rod 10 that first the front inlet side of charging basket can knock on first position detecting mechanism impels charging basket position detection rotating shaft 9 to rotate to an angle, be arranged on the detection that the lower end touching lever head 16 of charging basket position detection rotating shaft 9 outer ends knocks on position switch 17 with axle deflection and meet and discuss 18, the inner normal connection signal of closed output of making war of position switch 17, signal outputs signal to Controlling System by vacuum-sealing electrical equipment Connection Block 19, Controlling System starts vacuum heating chamber roller transmission system automatically.Charging basket moves under the acting in conjunction of preparation feed chamber roller transmission system and vacuum heating chamber roller transmission system, once the front inlet side of charging basket knocks second T shape test rod 10 on position detecting mechanism in the process of advancing, Controlling System can receive a connection signal, this signal impels vacuum heating chamber roller transmission system automatic retarding 50%, until the front inlet side of charging basket knocks the 3rd the T shape test rod 10 on position detecting mechanism in the process of advancing, Controlling System can receive a connection signal, this signal impels vacuum heating chamber roller transmission system automatically to stop, charging basket accurately stops in vacuum heating chamber.Vacuum heating chamber annealing process finishes and arrives while carrying charging basket to cooling room, Controlling System automatic sequence starts corresponding mechanism charging basket is transmitted toward cooling room, once the T shape test rod 10 in the disengaging configuration feeler mechanism of charging basket rear end, charging basket position detection rotating shaft 9 automatic reverse spinning reduction under return spring 12 effects is vertical state, the lower end touching lever head 16 that is arranged on charging basket position detection rotating shaft 9 outer ends meets and discusses 18 with the detection on axle deflection disengaging configuration switch 17, inner normal battle of position switch 17 recovered normally open, "off" signal outputs signal to Controlling System by vacuum-sealing electrical equipment Connection Block 19, only have three position detecting mechanisms all to export "off" signal, Controlling System just can be exported vacuum heating chamber without the signal of charging basket.The Main Function of brass axle sleeve 7 is charging basket position detection rotating shaft 9 to be conducted from vacuum heating chamber flue to the dissipation of heat of coming to watercooling jacket 6, guarantee that charging basket position detection rotating shaft 9 outer end temperature are unlikely to too high, the normal use temperature of setover switch 17.The Main Function that detects cylindrical shell 14 is by sealings such as the topworks of position detecting mechanism and position switch, guarantees the high vacuum environment of vacuum heating chamber.
