The stage amounts to the product application on numerical control press coming back
- source:TANAY CNC Machining
Main shaft of principle of structure of 1 press coming back: Drive workpiece to rotate. Truckle: XY axis workbench drives truckle to undertake extruding to workpiece by certain way. Lathe tool: Come back pressure lathe tool is used to undertake proper nap to workpiece end panel after finishing. Send makings orgnaization: Relevant movement sees below behavioral introduction. 2.
System of 2 numerical control designs logistic movement to pile up control by the M inside bracket, expect on and finish the machine program that after the behavioral order of makings can consult, adds. (1) send makings into / retreat (M06/M07) : Send work to to be able to be pushed makings the place that takes collet, work or material rest sends to cannot stop in this position in machining a process. (2) blow gas to leave / close (M08/M09) : Blow gas to undertake cooling to workpiece. (3) collet clamp / loose (M10/M11) : So that machine,clip holds work. (4) push makings into / retreat (M12/M13) : Send main shaft collet work by an air cylinder inside. (5) tailstock is close / loose (M14/M15) : Core club is squeezed to come out into club of the core in the process is being machined to prevent after reaching the designated position tailstock needs clamp. (6) discharge enters / retreat (M16/M17) : From inside collet workpiece the top comes out. (7) produce makings 1 into / retreat (M18/M19) : Produce makings 1 and produce makings 2 cooperate to assure to go up only every time a makings. (8) produce makings 2 into / retreat (M20/M21) : Produce makings 1 and produce makings 2 cooperate to assure to go up only every time a makings. (9) core club enters / retreat (M79/M78) : When workpiece is machined internally hole size has a demand, and come back press outward appearance to undertake unwarrantable inside hole size, the need when be being machined so puts core club will assure inside workpiece inside hole size. (10) come back press automation: XY axis workbench drives truckle to undertake extruding to workpiece by certain way, different workpiece species comes back press method to differ. 2.
3 automation come back press craft contrail to design (1) orbit design. The first kind of automation comes back if the graph is shown 3 times,press treatment contrail. The 2nd kind of automation comes back if the graph is shown 4 times,press treatment contrail. Using good point of means of the first kind of feed is process designing simple, workpiece surface is bright and clean had spent, but bring about workpiece easily to coarsen or pull, because this uses means of the 2nd kind of feed. Unilateral feed is bilateral feed pursues 3 automation come back press treatment contrail (1) unilateral feed is bilateral feed pursues 4 automation come back press treatment contrail (2) (2) orbit computation.
The feed with different set needs in different technology condition, need computation enters the circular arc in giving way every paragraphs to be in the length of XY direction, computational process basis pursues 5 computation are as follows. Graph reference of computation of 5 craft contrail pursues every paragraphs of circular arc is in Y2 of Y1 of Δ of Y direction length, Δ . . . The first paragraph of circular arc is in Δ Yn=K the 2nd paragraph of circular arc is in X1=sqrt(R2-(R-K)2) of Δ of X direction length X1 of Δ of X2=sqrt(R2-(R-2K)2)- of Δ of X direction length. . . Arc of N Duan Yuan is held in system of Xn-1 3 of Δ of Xn=sqrt(R2-(R-n*K)2)- of Δ of X direction length accuse an interface to design 3.
1 automatic picture chooses automatic mode to enter automatic picture from face plate key-press. Automatic picture falls to turn over page key to be able to adjust G01 feed fold by fluctuation. Auxiliary function key introduces below automatic picture: Form pauses: Turn over Bai Shicheng type to suspend carrying out by, disappear in vain instead by again form continues to carry out. Circulate: Turn over Bai Shicheng type to carry out treatment circularly a workpiece is carried out no longer, after turning over Bai Shicheng type to start, successive treatment workpiece keeps stopping. Computation to clear: Press 1 second to machine computation continuously meeting to clear. Collet: Collet intensifies / loose oil pump: Oil pump open / shut 3.
Face of 2 hands animation chooses type of hand movable mould to enter hand animation area from face plate. Key-press is controlled to be able to control XY by fluctuation below hand animation face two axes are losing directional feed. Hand animation face falls to turn over page key to be able to adjust G01 and hand to use feed fold by fluctuation. The hand assists function key introduction below animation face: The dot uses a test: Enter output to choose test picture by. To the knife: Enter pair of knife pictures by. Program setting: Enter form to choose a picture by. 3.
Picture of test of 3 output dot turns over page key to be able to check the switch between the picture in two through fluctuation. Output dot assists function key introduction below test picture: Collet / produce makings 1/ to produce makings 2/ to send makings / push makings / core club / tailstock / discharge / fall makings / blow air: All sorts of output check, leave to be shut by by. 3.
Picture of 4 pairs of knives turns over page key to be able to be in two to be opposite through fluctuation the switch between knife picture. To function key introduction assisting below knife picture: Memorial X1: Remember X of coordinate of instrument of little motorship engine to write MCM parameter #19. Memorial Y1: Remember Y of coordinate of instrument of little motorship engine to write MCM parameter #20. Memorial X2: X of 1 mechanical coordinate writes memorial lathe tool into MCM parameter #23. Memorial Y2: Y of 1 mechanical coordinate writes memorial lathe tool into MCM parameter #24. Memorial X3: X of 2 mechanical coordinate writes memorial lathe tool into MCM parameter #27. Memorial Y3: Y of 2 mechanical coordinate writes memorial lathe tool into MCM parameter #28. Return: Press return hand animation face. 3.
5 craft choose option of means of picture process designing: Input 0 when, the figure that the system chooses according to the user implements corresponding form, user cannot oneself choose form; Input 1 when, the user can choose a picture to issue his to choose form in form. Workpiece graph chooses: The sets beforehand figure with choice and the workpiece same appearance that need treatment, export the number of graphical top left corner, can automatic switch reachs form number corresponding form. Machine means choice: The figure with corresponding input chooses the treatment route of unilateral or bilateral feed, can automatic switch reachs form number corresponding form. Form assists function key introduction below choice picture: Return: Press return hand animation face. Parameter setting: Press enter parameter to set a picture. Workpiece graph choice is different enter different parameter to set a picture. 3.
Parameter of 6 spare partses installs a picture to input the relevant measure of the spare parts below this picture. Assist function key introduction: Craft parameter: Press enter craft parameter picture. Return: Press return form to choose a picture. 3.
Picture of setting of 7 craft parameter turns over page key to be able to be between picture of setting of 3 craft parameter through fluctuation switch. Own property right of home of 4 last words produces bed of accurate press coming back to already had 30 old histories, design, make, technical capability of production already had very great progress, a lot of technology index already achieved international advanced level, already formed export capacity. Development of domestic proper motion develops each model nicety comes back press equipment to be able to replace an entrance completely. Cost of foreign press coming back is high, of coequal function come back the 5-8 that controlling equipment abroad price is home times. Have hardware, software more departure plan cost, software makes expense often exceeds facility cost, although do not buy software, also want oneself to throw a large number of manpower, material resources 2 times to develop. Change, repair component same also person of be enslaved to be enslaved to. And mix trial-produce product when domestic equipment consign design software along with all the others consign, of component change time also has assure. Report is amounted to to connect system of PUTNC-H4-2 numerical control and two stages to amount to servo in be based on the research and development of press coming back has gained the new-style high-powered numerical control of compositive technology platform successful, it is the contribution that revitalizes for industry of machine tool of numerical control of homebred and own property right.
