Compacting flow process when producing according to need of production online change, also can be carried out on-line tuning when producing according to the shaping situation of product, reaching higher compacting precision.Concrete, the control program in the present invention comprises following two kinds of programming modes, and one is by arranging technological parameter, and according to technological process and mechanical location, workpiece size etc. generate each axle programming table automatically, and another kind is the programming table of each axle of direct editing.
Further, when adopting the mode of the programming table of each axle of direct editing, each axle has corresponding programming form, can programme in table to axle motion process.Be empty during the initialization of programming table, the editting function of programming table has interpolation a line, deletes a line, insertion a line, clear table.One step of this axle motion process of each behavior of programming table, comprise and perform instruction and executive condition, wherein executive condition can be sky.If comprise executive condition, then when executive condition meets, perform instruction; If do not comprise executive condition, then when lastrow executes, current line performs instruction and performs immediately.Axle is by the instruction sequences motion from top to bottom of programming table.Perform instruction and comprise location, wait for, synchronous etc., executive condition reaches a certain position for a certain step of other axles or other axles reach a certain step etc.
During programming, first, a line is added, by row first place, input the programming content that this row respectively arranges, then, by control overflow, add remaining row, finally, input all programming contents, preserve programming table, when programming table is preserved, can check programming content, check whether every a line can resolve to the movement instruction meeting definition.If it is legal to check, can successfully preserve programming table.
For making host computer unified to the function of motion control, pre-loaded function being programmed as an imaginary axis, therefore, also comprises the programming table of prestrain.
After the programming table editor of each axle preserves, in order to check the motion process of each axle whether to meet the requirements, can the curve movement of each axle be generated by programming table content and be shown on picture.
The curve that each axle generates comprises: position-time, Velocity-time, acceleration-time, acceleration-time graph.
Whether the editting function of formation curve comprises: carry out color to every bar curve, show and edit.
During formation curve, the programming content of each axle can be checked, in theory whether legal, as: to a programming table, the speed of lastrow is too little, and the position of next line possibly cannot reach; The programming instruction of upper punch axle is to expect that the position of boots axle the 8th step is for 200mm is as condition, if the program location of material boots axle the 8th step does not reach 200mm, then the condition of this step of upper punch then cannot meet, cannot formation curve.When occur cannot the situation of formation curve, for the ease of diagnosis, the curve that step legal in programming table has generated can be shown, can point out simultaneously, which position which of which axle walks cannot formation curve.
If during formation curve, inspection is passed through, successful formation curve, curve can be issued to motion controller and perform, and each axle of press can move according to the curve generated.
In order to verify whether press can make mold impingement mold damage when using each axial curve motion generated, host computer provides the Motion Simulation Function of press, use the profile graphics with the on all four front view of press size, in analogous diagram, each axle is consistent with actual press axle definition rule at zero point for zero point, each axle figure is according to each shaft position-time graph motion, if figure intersects, change color, each axle figure uses Transparent color, the shape of observable intersection when figure intersects.Copying can start, and suspends, and stops.Figure can drag, Scalable, the world coordinates at display mouse indication place, the coordinate of full-size(d).
The present invention and prior art compare, and its effect is actively with obvious.The present invention utilizes the motion of controller to upper punch axle, die axle, core bar axle and material boots axle to carry out independent adjustment, and action is carried out in the instruction shown by programming, achieves the accurate control of metal dust electric pressing machine compacting flow process, improves traditional handicraft.
