Summary of the invention
The purpose of this utility model is that the engine for automobile cylinder cap adopts 60-90 degree centigrade of water to quench and the existing the problems referred to above of materials frame usually in the solution prior art, provides a kind of no material frame mode air-cooled quenching device.The utility model designs the air-cooled quenching device of a kind of no material frame mode, comprise the quenching device body, breeze fan, the air channel, the workpiece rollgang, feeding gate, it is characterized in that: in the quenching device body, be provided with a wind quenching tuyere, wind quenching tuyere is made up of two halves up and down, wind quenching tuyere connects the air channel, the other end in air channel is picked the wind blower fan, be provided with spreader plate in the air channel, in the wind quenching tuyere of two halves up and down, be provided with several flow deflectors, the flow deflector front end is given a dinner for a visitor from afar, the flow deflector end is connected to tuyere, and the end of workpiece rollgang connects the feeding gate place, and the front end of workpiece rollgang connects the workpiece process furnace.It is characterized in that: the tuyere that flow deflector connected of the wind quenching tuyere setting of two halves is a width-adjustable joint tuyere up and down.It is characterized in that: the workpiece rollgang is inclined to set, and end is lower than front end.It is characterized in that: above the quenching device body, be provided with the air draft aerofoil fan.It is characterized in that: be provided with temperature measuring equipment above air channel and quenching device body, the air channel is provided with the wind speed proofing unit.The utility model has the advantages that the wind quenching technology has following advantage:
1: quenchant is that air advanced simple filtering and handles and just can be recycled,
2: do not produce the waste water environmental pollution in the treating processes and can reach very low limit,
3: cooling rate is adjustable during quenching, can be at various Al-alloy parts treatment process,
4: eliminate by the unrelieved stress of control quenching velocity after, improve its mechanical property and working load and prolong engine life with aluminum alloy casting thermal treatment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise quenching device body 1 among the figure, breeze fan 2, air channel 3, workpiece rollgang 4, feeding gate 5, it is characterized in that: in the quenching device body, be provided with a wind quenching tuyere 6, wind quenching tuyere is made up of two halves up and down, wind quenching tuyere connects the air channel, the other end in air channel is picked the wind blower fan, be provided with spreader plate 7 in the air channel, in the wind quenching tuyere of two halves up and down, be provided with several flow deflectors 8, the flow deflector front end is given a dinner for a visitor from afar, the flow deflector end is connected to tuyere 9, the end of workpiece rollgang connects the feeding gate place, and the front end of workpiece rollgang connects workpiece process furnace 10.It is characterized in that: the tuyere that flow deflector connected of the wind quenching tuyere setting of two halves is a width-adjustable joint tuyere up and down.It is characterized in that: the workpiece rollgang is inclined to set, and end is lower than front end.It is characterized in that: above the quenching device body, be provided with air draft aerofoil fan 11.It is characterized in that: be provided with temperature measuring equipment 12 above air channel and quenching device body, the air channel is provided with wind speed proofing unit 13.
