Description
The utility model relates to a kind of press mold quenching apparatus, particularly a kind of Rotable quenching die.
In the bearing processing industry, can reach interior tough outer hard application requiring for guaranteeing bearing ring, need carry out quench treatment to it, adopt the press mold quenching method usually.Quenching press basic structure of the prior art is: press mold is by mobile tire, fixedly tire two portions are formed, but mobile tire relative fixed tyre bead under drive power source axially move back and forth, press mold is vertical setting, promptly fixedly tire down, mobile tire is last.During work, workpiece is placed fixedly on the tire, mobile then tire moves down, exerts pressure, with fixing tire with workpiece extruding jail, complete machine dropped in hoisting appliance control workpiece was quenched this moment.But facts have proved, adopt above-mentioned prior art that bearing is quenched and often do not reach performance requriements.
The purpose of this utility model is: overcome the deficiency of prior art, a kind of Rotable quenching die that can carry out quench treatment in high quality to the bearing workpiece is provided.
Design philosophy of the present utility model is such: high quenching quality comprises two aspects: workpiece hardening capacity, quench the back workpiece crisp firmly and not.For making not only firmly but also not crisp, need work-piece cools even by the bearing workpiece after quenching; For making the bearing workpiece, need work-piece cools speed fast by through hardening.And existing quenching technology makes the fast inadequately basic reason of work-piece cools speed be: workpiece immerses behind the cooling oil groove just transfixion, plays a part isolated temperature and conducts and just produce one deck steam film this moment between pyritous workpiece surface and low temperature oil; The even basic reason of inhomogeneous cooling is: cooling oil is because upper and lower sand pressure is different, so the oily temperature that the upper face of workpiece is contacted with lower surface also has difference.At the problems referred to above, the utility model adopts and to allow press mold drive the Workpiece Rotating mode, makes the steam film attenuate that workpiece surface forms or breaks, also play simultaneously stir around the effect of oil temperature; And press mold is horizontally set with by the level that vertically changes into puts, allow the horizontal rotation of workpiece, make the whole surface of workpiece can both touch the cooling oil of upper and lower differing temps intensity.
The utility model implementation is: a kind of Rotable quenching die, by body, body hoisting appliance, quenching press mold fixedly the piston rod of mold and mobile mold, mobile mold form, it is characterized in that:
(1), be provided with and can drive motor and the transmission mechanism thereof that the main shaft that joins with fixing mold rotates,
(2), the piston rod of mobile mold is cavity body, is provided with the rotating shaft affixed with mobile mold in it,
(3), fixedly mold, mobile mold and their piston rod and the axle all along same sea line setting.
When stating scheme in realization, can have a work supporting block that is socketed on the splined shaft, the axially parallel of splined shaft and press mold mold is provided with also that one one end is socketed in the mobile mold rotating shaft, the other end is socketed in the work supporting block push rod on this splined shaft.Fixing pusher tube of suit on the tire, this end is provided with return spring.Blocking cylinder of suit on the mobile tire, the piston cylinder Joint of this end and mobile tire.With respect to the work supporting block push rod, be provided with the work supporting block return spring along splined shaft.
Can also be when realizing the utility model with mobile tire, fixedly tire inside all has the cooling oil path, and all has some oil seepage holes on the two tire surfaces, have the interior oily path of oil transportation road and mobile tire in the rotating shaft of mobile tire and join.
The utility model has the advantages that:
1, cool time weak point, its quenching velocity has improved more than 1 times, has improved workpiece hardening capacity.
2, make the workpiece centre hardness bring up to HRC35-37 by original HRC28-29, surface hardness reaches HRC63-68.
3, the workpiece interior tissue reaches the 2-3 level.
4, the workpiece martensitic transformation of quenching back is thorough, residual austenite is few, is difficult for grinding cracks.
Accompanying drawing is the utility model example structure synoptic diagram.
Below in conjunction with drawings and Examples the utility model is done further narration:
The utility model of showing in the accompanying drawing comprises body 3, mobile tire 6, blocking cylinder 4, the piston cylinder 1 of mobile tire, piston rod 42 and rotating shaft 41, work supporting block 37 its push rods 39, the return spring 35 of splined shaft 34, carriage 37, fixedly tire 8 and main shaft 12 thereof, pusher tube 9 and charging ram 27, the return spring 26 of pusher tube 9, motor 13, the bevel pinion 16 of composition transmission gear for electric motor, bevel gear wheel 17 and axle 18 thereof, pinion(gear) 21, master wheel 25, parts such as gear 30 that driving splined shaft 34 rotates and tooth bar 31.As seen from the figure: press mold mold 6,8 two portions and their driving stems, axle are provided with on a sea line, promptly constitute " horizontal " structure.Mold has two kinds of actions during work: the relative clamping work pieces of two portions mold, it by mobile tire 6 vertically initiatively to fixedly tire 8 direction displacements realization; Mold clips workpiece and quenches at the fluid internal rotation, and this is by fixedly tire 8 active rotation, 6 driven realizations of mobile tire under motor 13 drives.
The utility model working process is such:
1, workpiece 7 is rolled on the carriage 37 by feed channel.
2, oil cylinder piston bar 42 promotes mobile tire 6 and advances, and mobile tire 6 enters workpiece 7 endoporus, and workpiece is continued pushing sleeve on fixing tire 8, this moment mold 6,8 with workpiece 7 clampings, under the axle pressure effect, be connected as a single entity.Workpiece is compressed into pusher tube 9 simultaneously; Being enclosed within carriage 37 that push rod 39 in the rotating shaft 41 will hold in the palm workpiece pushes a segment distance and makes it holding in the palm all the time workpiece to fixing tire 8 directions.
3, under hoisting appliance control, whole machine body 3 enters in the fluid.
4, workpiece in fluid, rotate, inside and outside Cooling Quenching: motor 13 and transmission mechanism thereof drive by main shaft 12 that fixedly tire 8, workpiece 7, mobile tire 6 rotate together.Simultaneously cooling oil is by oil-feed gland 43, and the oil transportation road 2 of rotating shaft 41 enters mobile tire 6, the fixing oily path 5 in the tire 8, and fluid enters workpiece endoporus raceway by the surperficial oil seepage hole 10 of tire and cools off then.
5, body 3 rises.
6, oil cylinder piston bar 42 is return.If workpiece is bonded at fixedly on the tire 8, will be pushed barrel 9 and releases by spring 26 and drop on the carriage 37; If workpiece is bonded on the mobile tire 6, will be dropped on the carriage 37 by blocking cylinder 4 retainings.At this moment carriage 37 will be return original position under the effect of spring 35 after piston rod 42 is return.
7, workpiece rolls out:
Being enclosed within the carriage 37 on the splined shaft, is power with the oil cylinder, by tooth bar 31, gear 30 splined shaft 34 is rotated, and workpiece is routed up the discharging road.
