Fig. 2 is the axial sectional diagrammatical view illustration along axle center of support bar.
Fig. 3 is the radial section schematic diagram of support bar.
Embodiment
In order to more fully explain implementation of the present utility model, there is provided embodiment of the present utility model.These implement real
Example is only to illustrate of the present utility model, and scope of the present utility model is not limited.
Explain with reference to accompanying drawing is further details of to the utility model, in accompanying drawing each mark for：1：Chassis；2：Pressing plate；3：
Support bar；4：Lower spring pad；5：Holddown spring；6：Upper spring shim；7：Nut；8：The pad of heat treatment；9：Suspension ring；30：
Axial hole；31：Groove；32：Radial hole；As shown in drawings, ring washer is heat-treated buckling deformation means for correcting, including upper surface is
The chassis 1 of plane, is fixedly installed on the support bar 3 of vertical direction, support bar 3 on chassis 1 and is arranged pressing plate 2, in support bar 2
Top board is arranged with lower spring pad 4, holddown spring 5, upper spring shim 6 successively upwards, the support bar on upper spring shim 6
On be provided with nut 7, the top of support bar 2 is equipped with screw thread with nut, and when ring washer is heat-treated, ring washer is set in into pressure
On support bar on plate and chassis, 8 show the ring washer that superposition is set on support bar, rotate nut by upper spring shim
It is put into after compression in tempering furnace and carries out temper, described chassis and pressing plate is the circular slab of middle with hole, along circular slab
Multiple holes circumferentially are offered, optimization, described support bar is is arranged on center chassis, and support bar is round bar, along round bar axle center
Offer and also offer hole on the axial hole 30 of insertion support bar whole length, chassis with axial hole corresponding position, axial hole connection
Chassis lower surface is passed to, support rod outer surface a plurality of groove is provided with, 31 show groove, groove length direction and support bar
It is axially consistent, offer multiple radial holes being connected with axial hole in a groove, 32 show radial hole, this mode can be with
Ensure that hot-air flows in heat treatment process, each spot temperature is uniform, optimization, and hoisting ring is connected with post upper,
Hoisting ring can the convenient use plant equipment handling when workpiece is heavier.When ring washer is tempered, according to loading onto pad shown in Fig. 1
Piece, first tightens locking nut 7, and at this moment upper spring shim 6 will be pressure transmission to holddown spring 5, then again by compressing bullet
Spring 5 passes to lower spring pad 4, then passes to pressing plate 2, is ultimately transferred to workpiece 8, as locking nut 7 is moved downward, spring
Gradually compressed, until last, spring is depressed into the elastic limit of maximum, and now, the elastic force of spring is just consequently exerted at ring washer
On applied stress.When ring washer is tempered, the equipment mechanism is positioned in tempering furnace, with the rise of temperature,
Carbon atom in steel starts to separate out, and martensite amount of distortion reduces, hardness reduction, moulding increase.The ring washer of warpage is in spring force
In the presence of start correction, with the reduction of deflection, warpage degree start weaken；It is not tempered the ring washer compressed before originally
Between start to occur in that gap, now spring in equipment mechanism promotes the clamping platen 2 of lower spring pad 4, and pressing plate 2 compresses planchet
Piece 8, so as to reduce the space between pad and pad, remains that external force is constant.When heat treatment temperature is further raised,
Carbon atom in steel is further separated out, and martensite amount of distortion further weakens, and hardness is reduced again, moulding to increase again, then work
Part buckling deformation in the presence of external force reduces again, the gap increase between workpiece and workpiece, now the bullet in equipment mechanism
The clamping platen 2 of spring push the spring lower gasket 4, repeatedly said process is until last again, when deformation is wholly absent, and spring is not yet
Extend again, the ring washer of warpage also constantly discharges the stress of itself during heat treatment, is completed in equipment mechanism
The correction of itself.
It is easy to use using above-mentioned ring washer fixing device mechanism, and in heat treatment process ring washer be subject to it is outer
Power remains constant, simple to operate, repeated multiple times can use, and significantly corrects the buckling deformation in ring washer, reduces
Production process, shortens the production cycle, improves product competitiveness, reduces production cost, it is ensured that product quality.
After embodiment of the present utility model is described in detail, one of ordinary skilled in the art is clearly understood that,
Above-mentioned claim is not departed from various change and modification can be carried out under spirit, it is all according to technical spirit of the present utility model
Any simple modification, equivalent variations and the modification made to above example, belong to the scope of technical solutions of the utility model,
And the utility model is also not only restricted to the embodiment of example in specification.
