Description

Technical Field

[0001] The invention belongs to the technical field of stamping die design, and discloses a waste chute expansion and arrangement method, and stores a recording medium and a system capable of executing the method program. Background Art

[0002] Each set of trimming and punching dies must use a waste chute. The function of the waste chute is to automatically export the waste out of the die and the press. Once the waste is not discharged smoothly, it will directly affect the production of the stamping automatic line.

[0003] In the past, the design of non-standard waste chutes was all manually simplified 3D design, which was only used as a manufacturing reference. The waste chutes were handmade by fitters with low dimensional accuracy, which resulted in the joints of the waste chutes being not smooth enough and waste accumulation occurring from time to time. Moreover, when there were multiple waste chutes, the efficiency of manual arrangement was too low, which easily caused waste of sheet metal. Summary of the invention

[0004] In view of the above problems, the present invention provides a method for expanding and distributing waste chutes, and the specific scheme includes the following steps:

[0005] S1. Select the upper surface DA1 of a single waste chute entity slideway and the side wall surface adjacent to the upper surface DA1, extract the bending line L1 where the upper surface DA1 intersects with the side wall surface; rotate all the side walls 90 degrees toward the upper surface DA1, unfold them, and merge them with the upper surface DA1, and extract the merged outer contour line L2;

[0006] S2. Take the lowest point PT1 of the outer contour line L2 as the horizontal reference plane DA2, obtain the intersection line L3 of the upper surface DA1 and the horizontal reference plane DA2; rotate the bending line L1 and the outer contour line L2 around the intersection line L3 to the horizontal reference plane DA2;

[0007] S3. Generate a part module by rotating all the outer contour lines L2 and the bending line L1 on the horizontal plane, project them onto the horizontal plane DA3, and extract the part number of each part module;

[0008] S4. Remove the overlapping state of the overlapping part modules by translating them to adjacent areas, and complete the physical expansion layout of the waste chute.

[0009] Further, S4 includes the following steps:

[0010] Take the geometric center point P2 of each part module after expansion and connect it to the coordinate origin P1 to generate a line segment P12. Set the multiple N according to the degree of overlap of the layout. Move the part module along the extension line of the line segment P12 in the direction away from the coordinate origin P1 by a distance of N lengths of the line segment P12 until the part modules no longer overlap, thus completing the physical expansion layout of the waste chute.

[0011] Compared with the prior art, the present invention realizes the intelligent unfolding and layout of the waste chute unfolding and layout structure through visual interactive interface operation, which can shorten the time by about 3 / 4 compared with the existing manual design method, reduce repetitive labor, and can be reused, which greatly shortens the waste chute unfolding design cycle, ensures the correct orientation design of each part, makes the waste chute design tend to be standardized, and reduces the design and manufacturing cost of the waste chute.

[0012] Another embodiment of the present invention is to provide a non-transitory readable recording medium for storing one or more programs including a plurality of instructions. When the instructions are executed, the processing circuit will execute the above-mentioned waste chute expansion and arrangement method.

[0013] Another embodiment of the present invention is to provide a waste chute expansion and arrangement system, including a processing circuit and a memory electrically coupled thereto, wherein the memory is configured to store at least one program, wherein the program includes a plurality of instructions, and the processing circuit runs the program to execute the above-mentioned waste chute expansion and arrangement method.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making innovative efforts are within the scope of protection of the present invention.

[0023] See the following appendix to this application specification Figure 1-5 , showing the waste chute expansion layout method:

[0024] There are two unfolding algorithms for sheet metal processing: unfolding by the neutral layer or unfolding by the inner surface. Since the accuracy requirements of the scrap chute are not very high and the sheet material is relatively thin, the errors produced by the two unfolding methods are at the same level, and the unfolding calculation by the inner surface will be simpler, so the inner surface unfolding method is used for layout processing.

[0025] First, select the upper surface DA1 (i.e., the inner surface of the bottom of the chute) of a single waste chute entity and the side wall surface adjacent to the upper surface DA1, and extract the bending line L1 where the upper surface DA1 and the side wall surface intersect; rotate all the side walls 90 degrees toward the upper surface DA1 and unfold them, and merge them with the upper surface DA1, and extract the merged outer contour line L2;

[0026] Take the lowest point PT1 of the outer contour line L2 as the horizontal reference plane DA2, and obtain the intersection line L3 between the upper surface DA1 and the horizontal reference plane DA2; rotate the bending line L1 and the outer contour line L2 around the intersection line L3 to the horizontal reference plane DA2;

[0027] Generate a part module by rotating all the outer contour lines L2 and bending lines L1 on the horizontal plane according to the part, project them onto the layout horizontal plane DA3, and extract the part number of each part module;

[0028] In order to separate the overlapping parts while taking into account the relative positions of the parts, the technicians can manually translate them one by one in the software. In order to improve efficiency, we use the linear amplification method to perform the layout as a whole: take the geometric center point P2 of each part module after expansion and connect the coordinate origin P1 to generate the line segment P12. According to the overlap degree of the layout, the multiple N=1 is set, and the part module is moved along the extension line of the line segment P12 in the direction away from the coordinate origin P1 by a distance of the length of the line segment P12, until the part modules no longer overlap, and the layout of all part modules is completed.
