Description
Technical field
The utility model relates to a kind of fast wind cold house for isothermal normalizing.
Background technology
Metal works blowing cold air after traditional fast wind cold house adopts centrifugal blower to heating, arrives predetermined technological temperature by work-piece cools.
Traditional fast wind cold house comprises: cooling chamber body, feeding gate and hoisting mechanism, discharge door and hoisting mechanism, centrifugal blower, intake stack, exhaust duct.
Traditional fast wind cold house course of work is: feeding gate is opened, and workpiece is transferred in fast wind cold house from heating furnace; Feeding gate is closed, and centrifugal blower is opened, and cold air is blown in air-cooling chamber by intake stack, workpiece is carried out cooling, and the air after heat exchange is discharged by exhaust duct; Work-piece cools is after predetermined technological temperature, and discharge door is opened, and changing of workpieces shifts out fast wind cold house.
Traditional fast wind cold house is owing to adopting quenching, is subject to pipeline windage and workpiece to the stopping of air-flow, cannot carry out all workpiece evenly coolingly, causes different workpieces non-uniform temperature; Workpiece windward side temperature declines fast, and lee face temperature declines slow, causes same workpiece temperature inhomogeneous, affects the product quality of workpiece.
Summary of the invention
The purpose of this utility model is to provide a kind ofly carries out, in isothermal normalizing Technology for Heating Processing engineering, workpiece being cooled fast to predetermined technological temperature at metal works, and cooling uniformly for the fast wind cold house of isothermal normalizing.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of fast wind cold house for isothermal normalizing, comprise air-cooling chamber body, be arranged on feeding gate and discharge door on air-cooling chamber body, control the feeding gate lifting mechanism of feeding gate folding, control the discharge door hoisting mechanism of discharge door folding, centrifugal blower, bottom and the top of described air-cooling chamber body arrange respectively intake stack and wind pipe, described wind pipe is divided into two-way after by centrifugal blower, the exhaust duct of leading up to is directly communicated with atmosphere, the return air duct of separately leading up to is connected with intake stack, described exhaust duct and return air duct junction are provided for changing the turnover panel governor motion of air flow.During use, feeding gate is opened, and workpiece is transferred in fast wind cold house from heating furnace; Feeding gate is closed, and exhaust duct is opened, and return air duct is closed, and centrifugal blower is opened, and cold air is sucked in air-cooling chamber by intake stack, workpiece is carried out cooling, and the air after heat exchange is discharged by exhaust duct; After cooling certain hour, return air duct is opened, and exhaust duct is closed, and the air after heat exchange enters intake stack by return air duct; Work-piece cools is after predetermined technological temperature, and discharge door is opened, and changing of workpieces shifts out fast wind cold house.It is cooling that the utility model takes the mode of air draught to carry out workpiece, thereby make different workpieces cooling velocity more even; The second half adopts hot air circulation, and the windward side of workpiece and the lee face temperature difference are reduced, and while guaranteeing work-piece cools, windward side and lee face temperature are more even.
As further improvement of the utility model, also comprise blower fan bracing frame, described centrifugal blower is arranged on blower fan bracing frame.The blower fan bracing frame that supports centrifugal blower is set separately, and the vibration producing while preventing blower fan work exerts an influence to air-cooling chamber body, guarantees the sealing of air-cooling chamber body.
In sum, the beneficial effects of the utility model are: work-piece cools speed is even, the having a narrow range of temperature of workpiece each several part, and the utility model is simple in structure, uses easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
As Fig. 1, the fast wind cold house for isothermal normalizing shown in Fig. 2 and Fig. 3, comprise air-cooling chamber body 1, be arranged on the feeding gate 2 on air-cooling chamber body 1 left surface and be arranged on the discharge door 3 on air-cooling chamber body 1 trailing flank, control the feeding gate lifting mechanism 2-1 of feeding gate 2 foldings, control the discharge door hoisting mechanism 3-1 of discharge door 3 foldings, by motor-driven centrifugal blower 5 and blower fan bracing frame 6, described centrifugal blower 5 and the motor that drives centrifugal blower 5 to rotate are all arranged on blower fan bracing frame 6, and blower fan bracing frame 6 and air-cooling chamber body 1 are at intervals to prevent that the vibration of centrifugal blower 5 from impacting the sealing of air-cooling chamber body 1, the bottom of described air-cooling chamber body 1 arranges intake stack 7, the top of inlet air plenum body 1 sets out wind pipeline 4, described wind pipe 4 connects centrifugal blower 5 and be divided into two-way after by centrifugal blower 5, the exhaust duct 8 of leading up to is directly communicated with atmosphere, the return air duct 9 of separately leading up to is connected with intake stack 7, the turnover panel governor motion 10 that described exhaust duct 8 and return air duct 9 junctions are provided for changing air flow.
In this description, do not do the part that specifies as feeding gate lifting mechanism 2-1 and discharge door hoisting mechanism 3-1 etc. is prior art, will not describe in detail herein.
The utility model for the course of work of the fast wind cold house of isothermal normalizing is: feeding gate 2 is opened, and workpiece is transferred in air-cooling chamber body 1 from heating furnace; Feeding gate 2 is closed, and exhaust duct 8 is opened, and return air duct 9 is closed, and centrifugal blower 5 is opened, and cold air is sucked in air-cooling chamber bodies 1 by intake stack 7, workpiece is carried out cooling, and the air after heat exchange is discharged by exhaust duct 8; After cooling certain hour, return air duct 9 is opened, and exhaust duct 8 is closed, and the air after heat exchange enters intake stack 7 by return air duct 9; Work-piece cools is after predetermined technological temperature, and discharge door 3 is opened, and workpiece transfer goes out air-cooling chamber body 1.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
