Description
Technical field
The invention belongs to field of machining, relate to the method that a kind of wire cutting machine tool that utilizes high speed travelling wire carries out processing wedged spiral groove by linear cutting.
Background technology
At present, at a high speed walk silk cutting machine tool DK7720, workbench X, the Y of this lathe has only two numerical control axles, can only control the rectilinear motion of both direction, molybdenum filament is in plumbness all the time when cutting, therefore can only cut straight wall X-Y scheme curved surface straight up and down.Can't on revolving body, process helicla flute, let alone that to process front end wide, the wedged spiral groove that the rear end is narrow.And wire cutting machine tool and processing wedged spiral groove need be controlled rectilinear motion and a rotation of both direction, so commonsense method can't be processed at all.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing wire cutting machine tool on revolving body, to process the spiral fluted processing wedged spiral groove by linear cutting.Technical solution of the present invention is, work metal is sleeved on the numerical control rotary rotating disk that drives with stepper, the bottom surface of numerical control rotary rotating disk installs on the auxiliary support apparatus that vertically is combined into by the built-up jig plate, auxiliary support apparatus is fixed on the workbench of wire cutting machine, again molybdenum filament is installed perpendicular to workbench by the guide wheel on guide wheel on the last coil holder and the following coil holder, the control molybdenum filament is according to the end face skew vertical center line Y-axis of program from the work metal cover, from the initial openend of spiral fluted along X to moving, in the numerical control rotary continuous rotation of disc, the feeding X numerical value of manually transferring leading screw to show according to switch board is corresponding to be driven auxiliary support apparatus with Y numerical value and moves a sidewall of cutting auger groove in the Y direction, finishes up to this sidewall cutting; The operation molybdenum filament is to the opposite direction motion of X, and simultaneously, the rotation direction of numerical control rotary rotating disk also rotatablely moves round about, and the Y that continues manually to transfer leading screw is to distance, and another sidewall of cutting spin slot withdraws from until molybdenum filament.
After machining a wedged spiral groove, the work metal axle sleeve revolved turn 90 degrees, the operation molybdenum filament is according to the end face skew vertical center line Y-axis of program from the work metal axle sleeve, from the initial openend of spiral fluted along X to moving, in the numerical control rotary continuous rotation of disc, that manually transfers that leading screw shows according to switch board drives auxiliary support apparatus with the corresponding Y numerical value of feeding X numerical value and moves a sidewall of cutting auger groove in the Y direction, finishes up to this sidewall cutting; The operation molybdenum filament is to the opposite direction motion of X, and simultaneously, the rotation direction of numerical control rotary rotating disk also rotatablely moves round about, and the Y that continues manually to transfer leading screw is to distance, and another sidewall of cutting spin slot withdraws from until molybdenum filament, finishes whole processing.
Advantage that the present invention has and beneficial effect, the present invention makes full use of the performance of existing wire cutting machine tool, the numerical control rotating disk that utilizes wire cutting machine tool to have, the numerical control rotary rotating disk is installed on the auxiliary support apparatus, make it vertical placement, together install on the workbench then and fix, utilize a servomotor control numerical control rotary dial rotation, the angle that workpiece is turned over, be converted into mobile distance, the establishment wire cutting program, servomotor control molybdenum filament is at the feeding rectilinear motion of directions X, in performing a programme, according to X straight line displacement, the Y feeding distance that input synchronously calculates is adjusted the work metal cover moving linearly in the rotation manually, so just can make machine tool process the three-dimension curved surface groove class part of a complexity on a revolving body.The present invention utilizes existing equipment, and the mode machining 3 D wedged spiral groove with numerical control rotation and manual mobile phase combination is moved in the employing numerical control, and easy and simple to handle, cost is low.
Fig. 1 is a schematic diagram of the present invention;
Fig. 2 is that A among Fig. 1 is to enlarged drawing.
The specific embodiment
After machining a wedged spiral groove, quilt processing metal cover 5 revolved turn 90 degrees, operation molybdenum filament 10 is according to the end face skew vertical center line Y-axis cover of program from work metal axle sleeve 5, from the initial openend 4 of helicla flute 16 along X to moving, when numerical control rotary rotating disk 6 constantly rotates, manually transfer leading screw 14 to drive auxiliary support apparatus 8 with the corresponding Y numerical value of feeding X numerical value and move a sidewall of cutting auger groove 16, finish up to this sidewall cutting in the Y direction according to switch board 1 is that show; Operation molybdenum filament 10 is to the opposite direction motion of X, and simultaneously, the rotation direction of numerical control rotary rotating disk 6 also rotatablely moves round about, and the Y that continues manually to transfer leading screw 14 is to distance, and another sidewall of cutting spin slot 16 withdraws from until molybdenum filament 10, finishes whole processing.
Embodiment
On the DK7720 wire cutting machine tool, work metal axle sleeve 5 is contained on the numerical control rotary rotating disk 6 that drives with stepper, the bottom surface of numerical control rotary rotating disk 6 installs on the interior shape face 7 of the auxiliary support apparatus 8 that vertically is combined into by the built-up jig plate, another side 15 with auxiliary support apparatus 8 is fixed on the workbench 13 then, so just can guarantee 13 one-tenth horizontal positioned of the centre of gyration and workbench of the metal axle sleeve 5 of clamping on the numerical control rotary rotating disk 6, and can rotate.Again with molybdenum filament 10 by guide wheel 3 and guide wheel 11 vertical installations on coil holder 2 and the coil holder 9.Molybdenum filament 10 is according to the end face skew vertical center line certain Y numerical value of program from metallic sheath 5, begin along X to moving from the initial openend 4 of helicla flute 16, when the numerical control rotary rotating disk 6 that is driven by stepper constantly rotates work metal cover 5, show according to switch board 1 with the corresponding Y numerical value of feeding X numerical value, manually transfer leading screw 14, drive auxiliary support apparatus 8 vertical X to direction move, make corresponding the reducing of Y numerical value of molybdenum filament 10, so just carry out a sidewall of cutting auger groove 16, when switching to work metal when overlapping the bottom end opening 12 of 5 groove terminal points, this sidewall cutting is finished.After finishing, as a same reason, molybdenum filament 10 is to the opposite direction motion of X, the rotation direction of numerical control rotary rotating disk 6 also rotatablely moves round about, the Y that continues simultaneously manually to transfer leading screw 14 cuts another sidewall of spin slot 16 to distance, is withdrawn into the outer end of metallic sheath 5 until molybdenum filament 10.Finish the cutting of helicla flute 16 like this.Because the variation of Y numerical value, an end opening 4 that just can make helicla flute 16 is greater than rotation bottom end opening 12, thereby it is next to process a wedged spiral groove.
If will process cross or in-line wedged spiral groove, work metal cover 5 revolved turn 90 degrees cutting groove 17, repeat to cut the program of first groove [16], both the second wedged spiral groove be can process, according to this, cross or in-line wedged spiral groove just can be processed.
