Description

Import the method for CAD archives generation spinning machine CNC procedure code

Technical field

The present invention relates to a kind of method of edit tool machine CNC procedure code, relate in particular to the method that a kind of CAD of remittance archives produce spinning machine CNC procedure code.

Background technology

Existing spinning machine; Like Fig. 8, shown in Figure 9, be provided with a base 30, combine a main spindle box 31 in the left side of base 30 end faces; Be provided with a main shaft 311 on the right side at main spindle box 31 tops; Right-hand at main shaft 311 is provided with a pushing and pressing seat 32 at the end face of base 30, is provided with at pushing and pressing seat 32 tops with cylinder pressure to promote and can be towards moving left and rotatable pushing and pressing spools 321; The forward and backward both sides of corresponding pushing and pressing seat 32, being provided with one respectively at the end face of base 30 can laterally move or the cutter tower 33 and a control device 34 of forward and backward advance and retreat along Z axle, X axle;

The lathe tool 331 and the break bar 332 that combine to select via rotation use at cutter tower 33; Wherein break bar 332 has 60 degree angles for the form that is obliquely installed and with the Z axle clamp; Be provided with a rocking bar 341 and a control knob group 342 at control device 34; The rear of corresponding main spindle box 31 is provided with cylinder pressure at the end face of base 30 and drives the adjutage 35 that extends towards right, the right side at corresponding main shaft 311 rears; Be provided with one at adjutage 35 and compress wheel 351, the right-hand member in base 30 combines a man-computer interface 361 as control and input action with a suspension arm 36 again.

When existing spinning machine uses; Right-hand member at main shaft 311 combines a die frame 37; At the right-hand member of die frame 37, to combine a mould 38 with main shaft 311 concentric forms, again the shaft core position of main shaft 311, die frame 37 and mould 38 wear one can eject processed finished products towards the right side knock-pin 39.When adding man-hour; As shown in Figure 9; It is the right-hand member that the center of circular rapidoprint 40 is resisted against mould 38; And rapidoprint 40 is gripped fixing towards moving left with pushing and pressing axle 321, then main spindle box 31 driving main shaft 311 are together with mould 38, rapidoprint 40 and together rotation of pushing and pressing axle 321.

Shown in figure 10, then cutter tower 33 advances towards rapidoprint 40, carries out deburring with 331 pairs of rapidoprints of lathe tool 40; Material 40 deburrings to be processed are backed out after accomplishing, and shown in figure 11, cutter tower 33 is changed to break bar 332; Drive the circulation of break bar 332 repeatedly to advance and retreat along arching trajectory; The rapidoprint 40 of being turned left successively rotation by the right side overlays in mould 38, make break bar 332 can cooperate against rapidoprint 40 outsides compress wheel 351, become finished product with each contact rapidoprint 40 and with the mode spinning of its extension; Shown in figure 12; After treating that circulation spinning process that break bar 332 draws a circle finishes, can be again with break bar 332 by right side withdrawing again after the profile of left refine finished product, promptly accomplish the mach process of spinning that has now after ejecting towards the right side with the finished product of knock-pin 39 rapidoprints 40 at last.

The mach process of aforementioned existing spinning is to carry out with the mode of procedure operation; Cutter tower 33 drive break bars 332 with the cyclic process process of repeatedly drawing a circle in, the CNC procedure code of its control is to let the master worker who sees service earlier, processes once with rocking bar as shown in Figure 8 341 and control knob group 342 operation break bars 332; The track that driving break bar 332 moves under the record in the process; Convert the processing that the CNC procedure code provides spinning machine to carry out repetition again into, when the break bar 332 of spinning machine moved, its cutter path all was positioned on spinning machine Z axle, the shaft staggered Z-X axle imaginary plane that forms of X; And the initial point of CNC procedure code is set in the center of spinning machine main shaft right-hand member; Yet so way needs experienced master worker to operate and can implement, and different dies also needs the master worker to process and can carry out through different trials; Therefore except degree of difficulty and cost are higher, process is trouble, consuming time very also.

Summary of the invention

Because existing spinning machine produces mode that break bar moves control CNC procedure code and need note down the manually-operated process that sees service and could produce, so produce the cost height and process bothers, shortcoming consuming time.For this reason, method of the present invention measures the profile of mould earlier, cooperates the parameter adjustment cutter path to change into the mode of CNC procedure code again according to mold profile, need not operate spinning machine in advance with manual work.

For achieving the above object, the present invention provides a kind of CAD of remittance archives to produce the method for spinning machine CNC procedure code, and its step comprises:

Measure mould output CAD archives: the die size that measures spinning machine in kind; Be the Z axle on computers with the transverse axis, the longitudinal axis is the Z-X coordinate system of X axle, and the wherein planimetric map of half side profile of mould symmetrical halves draws; During drafting the top of mold center is located at the initial point of Z-X coordinate; Again the axle center of mould is located at the Z axle of Z-X coordinate, is made the half side profile of mould be positioned at the four-quadrant of Z-X coordinate figure, then the planimetric map of completing is saved as the CAD archives;

Be written into the CAD archives and show die shape and machining profile: the CAD archives are written into computer and show die shape; Follow the thickness of revisal spinning machine rapidoprint; Make the half side profile of mould squint up and become machining profile along the X axle; The break bar of spinning machine is for tilting and with the Z axle clamp angle of 60 degree is arranged, and the intersection point of break bar and Z axle, X axle imagination tangent line is the break bar central point, the continuous contact trace that becomes of the break bar central point when break bar is contacted machining profile;
