As shown in fig. 1, the method for implementing a standard structure module design mainly includes the following steps:
step 101: and inputting the graphic elements and the related parameters. The input graphic elements and related parameters comprise an upper binder division Curve (CSUP) and a Stroke (ST).
Step 102: and preliminarily determining the positions of the guide plate and the side pins according to factors such as the correlation of the input curve and the guide plate side pin design rule, and obtaining a graph set which accords with the calculation rule.
For example, some interval sets, such as a (x) ═ f (csup), are derived by judgment.
Step 103: and (4) determining the positions of the guide plate and the side pins again by combining parts which can generate interference, and if the positions can be distributed, obtaining a conveniently-described pattern set such as points, finite elements and the like.
Here, the position of the guide plate and the side pins is determined again, and for example, a portion where interference may occur, such as a Punching Set (PS) or a CAM, and (a) are secondarily determined to determine whether there is a distributable position. If so, obtaining a spatial point set (P1) from the regenerated interval set (a 1); for example, such as: a1(x) ═ f (a, PS, CAM, …), and P1(x) ═ f (a 1).
If there are no deployable positions, a derivative line (CSUP1) is generated according to the upper binder division Curve (CSUP) and Punching Set (PS), wedge (CAM) and the like, and the derivative line (CSUP1) is traced back to step 102 for re-determination.
Step 104: and carrying out sampling calculation to obtain a graph set meeting the conditions.
The sampling calculation is to substitute the space points of the objects in the upper set into a series of mathematical models established according to the difference of the guide plate width W, the side pin design rule and the characteristics, eliminate the non-solution or poor solution, and output the solution to the solution set.
And the qualified graph sets comprise a guide plate coverage feature set, a side pin coverage feature set and the like.
Preferably, after the step 104, the method further includes a step 110: and (5) performing correlation interaction calculation to obtain nodes related to the guide plate and side pin calculation, and then executing the step 105. The method specifically comprises the following steps: the correlation interactive calculation refers to searching and analyzing a plurality of nodes related to the guide plate and the side pin according to factors such as logic rules, spatial position distribution and the like, detecting the detection size, calculating the weight, and classifying and marking according to a corresponding rule if the weight reaches a certain standard. The nodes related to the guide plate and side pin calculation refer to other nodes related to the guide plate and side pin calculation but not obtained by the design implementation process, such as a Punching Set (PS), a cutter block (St) and the like.
Step 105: judging whether the mutual logic and shape-bit relation among the parts meets the standard, if so, executing the step 106; otherwise, step 107 is performed.
Step 106: and (4) performing shape and position calculation, instantiating parameters, characteristics and graphic sets required by the standard structure module, and obtaining the parameters, characteristics and graphic sets required by instantiation.
Here, the process of performing the form and position calculation specifically includes: and correspondingly substituting the superior output result into mathematical models with different classifications and levels according to the classification to calculate, and combining different algorithms such as searching, transmission and the like according to different initial solutions to obtain a solution set meeting the constraint condition. Then, outputting a set of parameters, characteristics, graphs and the like required by instantiation meeting the standards of a preset standard structure module (taking a guide plate and a side pin as examples); that is, a set of parameters, features, graphics, etc. required for instantiation that is compliant with the design standard (including that which is compliant after revision) is output.
Step 107: and (5) performing interactive calculation before the instance, retrieving and marking out relevant nodes which do not accord with the data, backtracking to the problem node to perform correction calculation, and then returning to the step 104 to perform judgment again.
Here, the performing interactive calculation before the instance specifically includes: and calculating the guide plate and side pin virtual models according to the superior output, and assigning values for alternative characteristics, tool characteristics and the like. And the substitution characteristics, tool characteristics and other parts interact according to the mold design logic, the space form and position and the like, and whether the mutual logic, form and position and other relations among the parts meet the standard or not is judged.
Step 108: and carrying out instantiation processing to obtain a visual standard structure scheme and an assembly result.
Here, the instantiation process refers to driving the design software to generate a visual guide plate and side pins (including their related decoration features and entities) according to the previously output parameter, feature, graph, and other sets.
Step 109: and carrying out example post-interaction processing to obtain a final guide plate side-pinning scheme and related features, graphs, bodies, tree graph leaf nodes and the like thereof.
The method specifically comprises the following steps: the guide plate and the side pin body after the instantiation processing and the modification characteristics thereof are subjected to Boolean operation, upgrading and downgrading, characteristic transfer, node transfer and other operations with other related parts, integrated parts are fused, and the explicit node tree conforms to the habit of common mold design.
The method for realizing the design of the standard structure module has the following characteristics:
1) the module can automatically generate standard structures (such as guide plates, side pins and the like) required by the die through a series of calculation of mathematical models according to different inputs and determine the position relation of the standard structures without manual identification and design calculation.
2) The method can adapt to the randomness of original input, and the algorithm of each step has stronger adaptability, especially the miniaturization and sampling algorithm has strong universality. For example, the extracted feature set for position determination is obtained through a large number of operations under a certain mathematical model, and the calculation (and the derivation based on the calculation) is suitable for most scenes in mold design.
3) The method can adapt to the complexity of a design environment, and not only a certain standard structure (such as a guide plate, a side pin and the like) but also a plurality of other standard structures (such as a balance block, an elastic element and the like) are arranged in a space, and at the moment, a series of calculation judgment is carried out to obtain which standard structures have logic or shape and position association (or conflict) between the standard structures, and because the other standard structures also change along with the change of input, namely random to an algorithm, the method for calculation, retrieval and judgment has universality. The adaptability of a single mathematical model is limited, and the output result of a certain step is obtained by a bottom layer system and is actually the result of the comprehensive calculation of a plurality of mathematical models.
4) The rationality of the output standard structure 'shape' and 'position' can be improved along with the supervision of a mathematical model. As the samples known to the system increase, the fitness and rationality of the system output will continue to improve through the learning process. The problem of non-adaptability of the system can be continuously solved, and the knowledge accumulation is easier.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
