For filling the moving trolley of feeding furnace door, the mobile track of the carrier of workpiece is loaded；Have below furnace body and input and output material station
Foundation pit；
Furnace body is made of multiple furnace chamber units, and each furnace chamber unit has independent heating system, and each furnace chamber unit adds
Hot systems individually control；The heating system is located at inboard wall of furnace body, and is higher than the upper loading of carrier；Each furnace chamber unit into
The roof and side wall for expecting end are equipped with protrusion, form firedoor frame；The feeding furnace door of furnace body feed end is moved in moving trolley
Dynamic trolley moves horizontally in furnace body along track, realizes transfiguration；Furnace body discharge end sets discharging door, and discharging door moves up and down,
Realize discharging door switch；Feeding furnace door, the shape of discharging door are consistent with firedoor frame；
U-shaped through slot is had on the objective table of the carrier, the bar portion for heating workpiece passes through U-type groove and hangs on objective table,
Heating workpiece needs fire end to be positioned above, and the bar portion of sealing block inner end and heating workpiece is coincide, and sealing block injects U-shaped logical
Slot closely withstands the bar portion of heating workpiece.
It is heated with the utility model, heating workpiece is hung on objective table, needs fire end upward, non-heated end is in foundation pit
It is interior, insertion sealing block sealing；The carrier for hanging with heating workpiece is advanced forward along track, into furnace chamber, is repeated the above process, after
Continuous carrier ending connects, successively shove charge, after charging quantity reaches predetermined number, is loaded into material oven door sealing furnace with moving trolley
Chamber；Heating system is heated；When coming out of the stove, discharging door is opened, all carriers, feeding furnace door all move forward one in furnace
Station, first heating workpiece release furnace chamber, close discharging door, remaining workpiece continues to keep the temperature；It extracts sealing block after coming out of the stove out, hangs
Pincers clamping workpiece exits U-type groove and hangs away；It repeats the above process, completes discharging.
The utility model has the advantage that
1, so that heating workpiece is directly heated under vertical state, lifting when postorder die forging is facilitated to transport, and
And the time is saved, it is more advantageous to the forming of forging.
2, furnace body is made of multiple furnace chamber units, and each unit can be controlled separately heating system, when furnace body since furnace vehicle goes out
When having vacant position after furnace, then being blocked by movable fire door, the region of no heating workpiece can then turn off corresponding heating system,
Build and organize strong flexibility when production；
3, furnace body is made of multiple furnace chamber units, has the function of furnace chamber transfiguration, and furnace cavity structure is compact, and energy-saving effect is bright
It is aobvious；
4, by the track of the inside and outside connection of furnace body, can make carrier, feeding furnace door moving trolley recycle in orbit into
It comes out of the stove, saves the time, improve effect.
The utility model solves the problems, such as workpiece local heating and vertical heating, also achieves the function of furnace chamber transfiguration,
Energy-saving effect is obvious.
Detailed description of the invention
Fig. 1 is the utility model structure diagram,
Fig. 2 is furnace bassinet structure schematic diagram,
Fig. 3 is feeding furnace door structural schematic diagram,
Fig. 4 is the utility model to workpiece heated condition figure.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings.
Contact pin Fig. 1,2,3, the furnace body of the utility model is inside and outside having connection, for filling the moving trolley 5 of feeding furnace door, dress
Carry the mobile track 8 of the carrier 2 of heating workpiece；There is foundation pit 7 below furnace body and input and output material station.
Furnace body 1 is made of multiple furnace chamber units, and each furnace chamber unit has independent heating system, and each furnace chamber unit adds
Hot systems individually control, and heating system is controlled using common control mechanism.The heating system is located at inboard wall of furnace body, and
Higher than the loading on carrier.
The roof and side wall at each furnace chamber unit feed end are equipped with protrusion, form firedoor frame.Furnace body feed end into
Fire door is expected in moving trolley, and moving trolley moves horizontally in furnace body along track, is moved to feeding furnace door as needed
The corresponding position of furnace chamber used changes furnace chamber dischargeable capacity, to realize transfiguration.Furnace body discharge end sets discharging door, discharging door
It moves up and down, realizes discharging door switch.Feed furnace door body, the shape of discharging door body 501 are consistent with firedoor frame.
201 have U-shaped through slot 202 on the objective table of the loading 2, and the bar portion of heating workpiece 6 passes through U-type groove and hangs over loading
On platform, that heats workpiece needs fire end to be positioned above, and the bar portion of 3 inner end of sealing block and heating workpiece is coincide, and sealing block injects U
Type through slot closely withstands the bar portion of heating workpiece.
With the method for the utility model local heating, by the carrier 2 for loading heating workpiece along track march to furnace body into
Before the firedoor frame for expecting end, workpiece vertical state will be heated and be hung to above the U-shaped through slot 202 of objective table, heating workpiece passes through U-type groove
It hangs on objective table, that heats workpiece needs fire end to be positioned above, and non-heated end is downward, in foundation pit 7.Sealing block is from U
The insertion of type groove open end, is bonded with blank bar portion, forms sealing；
Carrier enters furnace chamber along track together with heating workpiece 6；It repeats the above process, completes subsequent heater part
Shove charge, carrier are successively fitted closely into each furnace chamber, until first carrier is bonded with the inner wall of discharging door 4,
Shove charge is completed；
Moving trolley feeding furnace door 5 enters the corresponding position that furnace chamber is moved to furnace chamber used from feed end, forms furnace chamber
Sealing, complete space；Control mechanism controls heating system 9 and starts to work, to the heating workpiece being located above in furnace chamber
Fire end is needed to carry out local heating；After the completion of heating, discharging door is moved up, and is opened, and feeding furnace door is to being pushed forward a station, by the
One carrier and heating workpiece release furnace chamber, close discharging door, heating workpiece continues to keep the temperature in furnace；Heating furnace will be pushed out
Outer, the sealing block extraction of U-shaped through slot is injected, clamps fire end with " the heavy forging tongs " that the applicant applies on the same day, it will
It exits and hangs away in U-type groove from carrier；
Carrier, moving trolley after coming out of the stove march to feed end along track, complete the local heating of another non-fire end.
Direction is backwards when the mobile platform 502 of moving trolley is mobile in orbit.
Referring to Fig.1, Fig. 3, feeding furnace door 502 are fixedly mounted on the front end of moving trolley 501, and moving trolley realizes that fire door exists
While movement on track, plays the role of balancing fire door weight, prevent fire door from toppling.
The utility model solves the problems, such as that workpiece local heating need to be heated and heats vertically, also achieves furnace chamber transfiguration
Function, energy-saving effect are obvious.
