Description
Technical field
The utility model belongs to heat treatment of workpieces technical field, and in particular, provide a kind of radial outflow cooling heat work for the treatment of device, this equipment is used for the quenching to dish type product centre hole, controls workpiece core rate of cooling.
Background technology
In normal operation, require that the wheel hub position of disk type work has high yield strength and low cycle fatigue property, wheel rim position has high intensity and better low cycle fatigue property.At present, disk type work thermal treatment rear-wheel hub position intensity is generally on the low side, its major cause is that the average grain size at this position is greater than wheel rim position by analysis, namely consider from thermal treatment process angle, in the process air cooler of solution heat treatment, the average rate of cooling in wheel hub position is lower than wheel rim position, and the grain-size causing wheel hub position is bigger than normal.Therefore, original heat treatment tooling has had a strong impact on the mechanical property at disk type work wheel hub position and wheel rim position, and the speed of cooling that can not solve diskware wheel hub position, lower than the situation at wheel rim position, needs improvement badly.
Summary of the invention
The purpose of this utility model is to provide a kind of radial outflow cooling heat work for the treatment of device, improve the mechanical property of disk type work, by adopting rational thermal treatment equipment, the average rate of cooling at wheel hub position is improved in heat treatment process, reduce the mean sizes of wheel hub position crystal grain, improve its intensity, thus better meet the duty requirements of diskware.
The utility model comprises urceolus 1, inner core 2, nozzle 3, tracheae 4, upper fixed link 5, upper padding plate 6, lower fixed link 7, lower bolster 8, screw rod 9, support 12.Upper fixed link 5 is welded on the top of inner core 2, suitable for reading parallel with inner core 2, and lower fixed link 7 is welded on the below of inner core 1, and welding position can adjust as required.Upper padding plate 6 and lower bolster 8 are welded on the inwall of urceolus 1, and welding position can just make fixed link 5 and lower fixed link 7 be positioned on upper padding plate 6 and lower bolster 8.Screw rod 9 will penetrate inner core 2 and hold out against nozzle 3, and tracheae 4 will be enclosed within nozzle 3.The Fig. 2 assembled will be placed on support 12 fixing.
Urceolus 1, inner core 2, upper fixed link 5, upper padding plate 6, lower fixed link 7, lower bolster 8, screw rod 9, support 12 are made by stainless steel.
Nozzle 3, screw rod 9 be arbitrary size, any materials.
Tracheae 4 is the flexible pipe of any materials matched with nozzle 3.
This equipment divides inside and outside three layers.Outermost layer is urceolus 1, adopts the device that to fix with the similar stainless steel tube of hole size in disk type work; Middle one deck is inner core 2, adopts than outer slightly thin stainless steel tube; Innermost layer is air outlet, is formed by connecting by nozzle 3 and tracheae 4.Mutually support with fixed link 5, upper padding plate 6, lower fixed link 7, lower bolster 8, screw rod 9 between three layers, and will make to interfix between three layers and detachable.This frock should ensure enough strong wind-force, ensures that diskware wheel hub wind-engaging is even again, makes the average rate of cooling in wheel hub position close to the average rate of cooling in wheel rim position.And trend, the size of wind when will resolve air-out, and ensure that wind is out diffused in set scope.
Operationally need diskware to be processed when being heated to certain temperature in heat treatment furnace, this device is well placed.Move to after diskware hangs out in stove directly over this device, make this device ectonexine and diskware keep vertical, the wind gone out is vertical with diskware also can make wind evenly blow to diskware key position.Air outlet well should be fixed on the internal layer of device, can ensure that wind direction is constant, frock invariant position during air-out when wind increases.
When diskware come out of the stove pendulum at commitment positions time, air-supply at once, adjust wind-force size, within allowing one powerful wind during air-out be diffused in frock outer layer pipe inside diameter ranges, and steel pipe is just to diskware wheel hub, and diskware wheel rim at room temperature air cooling, thus reach and make wheel hub different with the wheel rim type of cooling but the object that performance is similar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the longitudinal section structural map of embodiment of the present utility model.
In figure, urceolus 1, inner core 2, nozzle 3, tracheae 4, upper fixed link 5, upper padding plate 6, lower fixed link 7, lower bolster 8, screw rod 9, workpiece 10, cooling gas 11, support 12.
Embodiment
The utility model comprises urceolus 1, inner core 2, nozzle 3, tracheae 4, upper fixed link 5, upper padding plate 6, lower fixed link 7, lower bolster 8, screw rod 9, support 12.Upper fixed link 5 is welded on the top of inner core 2, suitable for reading parallel with inner core 2, and lower fixed link 7 is welded on the below of inner core 1, and welding position can adjust as required.Upper padding plate 6 and lower bolster 8 are welded on the inwall of urceolus 1, and welding position can just make fixed link 5 and lower fixed link 7 be positioned on upper padding plate 6 and lower bolster 8.Screw rod 9 will penetrate inner core 2 and hold out against nozzle 3, and tracheae 4 will be enclosed within nozzle 3.The Fig. 2 assembled will be placed on support 12 fixing.
