Description
Technical field
The utility model relates to air cooling system, especially relates to isothermal normalizing air cooling system.
Background technology
Gear forgings in process of production, needs to carry out isothermal normalizing thermal treatment according to processing requirement, reaches the grain refining and distribution of carbides homogenizing that make gear forgings.At present, the mode of quenching is taked in the thermal treatment of gear forgings isothermal normalizing more, is placed in air-cooling chamber carries out air-cooled process by the gear forgings taken out in forging furnace; Extraneous cold wind is sent into from air-cooling chamber blast inlet through gas blower, then discharges from air-cooling chamber air outlet and is taken away by heat.The deficiency existed in above-mentioned air-cooled process is: be positioned at the gear forgings temperature of air-cooling chamber air inlet lower than the gear forgings temperature being positioned at air-cooling chamber air outlet place, namely the temperature distributing disproportionation in air-cooling chamber is even, cause the same batch of gear forgings normalizing temperature of loading in air-cooling chamber to occur difference, reduce the heat treated quality of gear forgings isothermal normalizing.
Summary of the invention
The utility model object is to provide a kind of isothermal normalizing air cooling system.
For achieving the above object, the utility model takes following technical proposals:
Isothermal normalizing air cooling system described in the utility model, comprises air-cooling chamber, gas blower, exhaust duct and PLC; The blast orifice of described gas blower is communicated with forward air supply duct and reverse air supply duct by teesaddle joint; Described forward air supply duct is connected with the first air port of described air-cooling chamber by forward air-supply electrically-controlled valve, and described reverse air supply duct is connected with the second air port of air-cooling chamber by electrically-controlled valve of oppositely blowing; Described exhaust duct is connected with reverse air supply duct respectively by forward air draft electrically-controlled valve, be connected with forward air supply duct by reverse air draft electrically-controlled valve; Blow with gas blower, forward respectively electrically-controlled valve, oppositely the blow input control end of electrically-controlled valve, forward air draft electrically-controlled valve and reverse air draft electrically-controlled valve of the output control terminal of described PLC is electrically connected.
The utility model advantage is the homogeneous temperature consistence improved in described air-cooling chamber, thus reaches the grain refining and distribution of carbides homogenizing that make air-cooling chamber internal wheel forging, improves the heat treated quality of gear forgings isothermal normalizing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, isothermal normalizing air cooling system described in the utility model, comprises air-cooling chamber 1, gas blower 2, exhaust duct 3 and PLC 4; The blast orifice of gas blower 2 is communicated with forward air supply duct 5 and reverse air supply duct 6 through teesaddle joint; Forward air supply duct 5 is connected with the first air port 8 of air-cooling chamber 1 by forward air-supply electrically-controlled valve 7, and reverse air supply duct 6 is connected with the second air port 10 of air-cooling chamber 1 by electrically-controlled valve 9 of oppositely blowing; Exhaust duct 3 is connected with reverse air supply duct 6 respectively by forward air draft electrically-controlled valve 11, be connected with forward air supply duct 5 by reverse air draft electrically-controlled valve 12; Blow with gas blower 2, forward respectively electrically-controlled valve 7, oppositely the blow input control end of electrically-controlled valve 9, forward air draft electrically-controlled valve 11 and reverse air draft electrically-controlled valve 12 of the output control terminal of PLC 4 is electrically connected.
Utility model works principle is summarized as follows:
The opening and closing of gas blower 2, forward air-supply electrically-controlled valve 7, reverse air-supply electrically-controlled valve 9, forward air draft electrically-controlled valve 11 and reverse air draft electrically-controlled valve 12 are by PLC 4(programmable logic controller) control.
When needing to carry out isothermal normalizing thermal treatment to the gear forgings in air-cooling chamber 1, first oppositely air-supply electrically-controlled valve 9 and reverse air draft electrically-controlled valve 12 is closed, open forward air-supply electrically-controlled valve 7 and forward air draft electrically-controlled valve 11, then gas blower 2 is opened, extraneous cold wind enters in air-cooling chamber 1 through forward air supply duct 5 from the first air port 8, and after lowering the temperature to gear forgings, through the second air port 10, oppositely, air supply duct 6, forward air draft electrically-controlled valve 11 are discharged from exhaust duct 3.The time of forward air-supply sets according to manufacturing technique requirent, when after the forward air-supply time reaching production technique setting, PLC 4 exports control signal and closes forward air-supply electrically-controlled valve 7 and forward air draft electrically-controlled valve 11, open oppositely air-supply electrically-controlled valve 9 and reverse air draft electrically-controlled valve 12 simultaneously, now extraneous cold wind enters in air-cooling chamber 1 through reverse air supply duct 6 from the second air port 10, after gear forgings is lowered the temperature through the first air port 8, forward air supply duct 5, oppositely air draft electrically-controlled valve 12 discharge from exhaust duct 3.
The utility model, by carrying out forward and reverse alternately air-supply in air-cooling chamber 1, reaches the consistent object of gear forgings temperature made in air-cooling chamber 1.
