A kind of processing method of the aluminium alloy thin-walled discoid part of T4Technical field
The present invention relates to the processing of mechanical processing technique technical field more particularly to a kind of aluminium alloy thin-walled discoid part of T4Method.
Background technique
Thin-walled discoid part has a wide range of applications in each industrial department in national economy, however, working as thin-walled diskWhen the material of shape part is aluminium alloy, since aluminum alloy material intensity is weak, poor rigidity, the work when processing this kind of thin-walled discoid partPart easily generates deformation, influences the machining accuracy and processing quality of part.For a long time, the processing of aluminium alloy thin-walled discoid partAs a technical problem urgently to be solved among machine cut machining process.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of processing methods of the aluminium alloy thin-walled discoid part of T4.
The present invention is achieved by the following technical programs.
The present invention provides a kind of processing method of aluminium alloy thin-walled discoid part of T4, comprising the following steps:
Step 1: providing cylindrical blank, carries out machining to blank using lathe, cuts off blank surface major part materialMaterial, and appropriate roughing surplus is reserved in blank periphery and both ends of the surface, obtain workpiece；
Step 2: Milling Process is carried out to workpiece described in step 1 using milling machine, cuts off workpiece surface roughing surplusIn some materials, and reserve allowance for finish appropriate；
Step 3: the workpiece after completion Milling Process in step 2 is subjected to ageing treatment；
Step 4: the workpiece after completion ageing treatment in step 3 is corrected；
Step 5: turnery processing is carried out to the workpiece after completing correction in step 4 using lathe, cuts off excircle of workpieceAllowance for finish on face and two end faces；
Step 6: Milling Process is carried out to the workpiece after completing turnery processing in step 5 using milling machine, cuts off workpieceSome materials on two end faces obtain each shape feature on two end faces of workpiece.
Roughing surplus described in step 1 is with a thickness of 1mm.
Carrying out Milling Process described in step 6 further includes obtaining each shape feature on one end face of the workpieceLater, Milling Process will be continued between the workpiece turning, obtains each shape on another end face of the workpieceFeature.
Carrying out machining to blank using lathe described in step 1 is by clamping with three-jaw chuck by blank in latheIt is carried out on main shaft.
Workpiece is passed through into auxiliary mould clamping in vehicle when turnery processing described in step 5, Milling Process described in step 6It is carried out on bed main shaft or milling machine table.
The auxiliary mould includes bottom plate and pressing plate, and bottom plate is fixedly connected with the lathe spindle or milling machine table, pressurePlate and bottom plate are fixed together and the workpiece are jumped the queue between bottom plate and pressing plate.
Shape feature described in step 6 includes boss, step and through-hole.
The beneficial effects of the present invention are: technical solution of the present invention is used, aluminium alloy thin-walled discoid part is optimizedProcessing technology sequence, i.e., carry out ageing treatment between roughing process and finishing step and correcting process, ageing treatment goneIn addition to remaining in the remaining cutting thermal stress in workpiece during roughing, makes workpiece in subsequent finishing stage, reduce workThe deformation that part is generated by remaining cutting heat stress influence lays a good foundation to improve processing quality and machining accuracy, corrects workSequence has modified workpiece outer contour shape, size, ensure that the finished product passing rate of processing of part, in addition, the present invention is also finishingUsing suitable clamping workpiece mode in stage, it is effective against the shear action power acted on workpiece, is further ensuredMachining accuracy and processing quality.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
The present invention provides a kind of processing method of aluminium alloy thin-walled discoid part of T4, as shown in Figures 1 to 4, including it is followingStep:
Step 1: providing cylindrical blank, carries out machining to blank using lathe, cuts off blank surface major part materialMaterial, and appropriate roughing surplus is reserved in blank periphery and both ends of the surface, obtain workpiece；It is preferred that roughing surplus is with a thickness of 1mm.Carrying out machining to blank using lathe is to carry out blank on lathe spindle by clamping with three-jaw chuck.
Step 2: Milling Process is carried out to workpiece in step 1 using milling machine, is cut off in workpiece surface roughing surplusSome materials, and reserve allowance for finish appropriate；
Step 3: the workpiece after completion Milling Process in step 2 is subjected to ageing treatment；
Step 4: the workpiece after completion ageing treatment in step 3 is corrected；
Step 5: turnery processing is carried out to the workpiece after completing correction in step 4 using lathe, cuts off excircle of workpieceAllowance for finish on face and two end faces；Turnery processing in step 5, workpiece passed through when Milling Process in step 6 it is auxiliaryFrock clamping is helped to carry out on lathe spindle or milling machine table.
Step 6: Milling Process is carried out to the workpiece after completing turnery processing in step 5 using milling machine, cuts off workpieceSome materials on two end faces obtain each shape feature on two end faces of workpiece.Milling in step 6 is carried out to addWork further includes after obtaining each shape feature on one end face of workpiece, adding milling is continued between workpiece turningWork obtains each shape feature on another end face of workpiece.Shape feature includes boss, step and through-hole.Auxiliary mouldIncluding bottom plate and pressing plate, bottom plate is fixedly connected with lathe spindle or milling machine table, and pressing plate and bottom plate are fixed together simultaneouslyWorkpiece is jumped the queue between bottom plate and pressing plate.
Using technical solution of the present invention, the processing technology sequence of aluminium alloy thin-walled discoid part is optimized, i.e., is slightly being addedAgeing treatment and correcting process are carried out between work process and finishing step, ageing treatment remains in during eliminating roughingRemaining cutting thermal stress in workpiece, makes workpiece in subsequent finishing stage, reduces workpiece by remaining cutting heat stress influenceAnd the deformation generated, lay a good foundation to improve processing quality and machining accuracy, correcting process have modified workpiece outer contour shape,Size ensure that the finished product passing rate of processing of part, in addition, the present invention is also in finishing stage using suitable clamping workpieceMode is effective against the shear action power acted on workpiece, further ensures machining accuracy and processing quality.
