Problems solved by technology

The existing one-size-fits-all rectangular raw material sheet layout blanking method cannot meet the "one-size-fits-all" process requirements, and the processing is difficult. The "one-size-fits-all" process requires cutting from one end of the rectangular plate to the other end along a straight line, and dividing it into Two independent rectangular parts, the cutter can only go in a straight line, and cannot turn or stop during the cutting process, that is, each cut will divide the plate into two
Moreover, in the existing single-size rectangular raw material plate layout and blanking method, the rectangular workpieces with small area are usually discharged first, and the rectangular workpieces with large area are left behind for discharge, resulting in a higher utilization rate of the former part of the plate and a higher part of the latter. The utilization rate is extremely low, so that the overall utilization rate of the board is poor

Embodiment 1

[0059] The method for fast nesting of rectangular workpieces facing single-size plates in this embodiment, such as figure 1 shown, including the following steps:

[0060] Step 1, the step of traversing workpieces, input the initial data of several rectangular workpieces to be discharged, and traverse the initial data of all rectangular workpieces to be discharged;

[0061] Step 2, the step of laying out the first rectangular workpiece, quickly recommending a piece of the rectangular workpiece as the first rectangular workpiece, and discharging, the first rectangular workpiece is discharged according to the priority of the lower left, lower right, upper left or upper right, and the The first rectangular workpiece is placed in the lower left corner, lower right corner, upper left corner or upper right corner of the rectangular single plate;

[0062] Step 3, the step of dividing the area to be laid out, cutting the single plate along the long side or short side of the first rect...

Embodiment 2

[0115] Test the method for rapid layout of rectangular workpieces facing single-size plates in Example 1, and design 21 sets of test case sets. The specifications and quantities of the rectangular workpieces in each set of test case sets are different, and the specifications of the single plate are also different. , test the rapid layout method for rectangular workpieces facing single-size plates in this embodiment, corresponding to the quantity of the single plate that needs to be used in each group of test case sets, the utilization rate and the layout time of the overall layout plan, the test results As shown in Table 1:

Abstract

The present invention discloses a rapid stock layout method of rectangular workpieces for a single specification board. The rapid stock layout method comprises: (1) a workpiece traversal step of inputting initial data of a plurality of to-be-arranged rectangular workpieces, and traversing the initial data of all the to-be-arranged rectangular workpieces; and (2) a first rectangular workpiece stock layout step of rapidly recommending and arranging a rectangular workpiece as the first rectangular workpiece, arranging the first rectangular workpiece with priority arrangement sequences of left lower, right lower, left upper and right upper, and putting the first rectangular workpiece at a left lower corner, a right lower corner, a left upper corner or a right upper corner of a rectangular single board. According to the rapid stock layout method of rectangular workpieces for the single specification board, a 'clean cut' process requirement is satisfied by a blanking stock layout process, stock layout speed is fast, the total utilization rate of the board is high, manufacturing cost of enterprises is largely reduced, requirements of the enterprises on multispecies concentrated blanking are satisfied, and great benefits are brought for blanking production and selection of the manufacturing enterprises.

Description

technical field [0001] The invention relates to the field of blanking and layout methods for plates, in particular to a rapid layout method for rectangular workpieces facing single-size plates. Background technique [0002] In the fields of sheet metal processing, glass processing, furniture manufacturing, clothing tailoring, etc., it is often necessary to cut rectangular workpieces of various specifications on a single-size rectangular raw material plate, so how to perform layout blanking on a single-size rectangular raw material plate To improve the utilization rate of raw materials has become a matter of great concern to the production of enterprises. The existing one-size-fits-all rectangular raw material sheet layout blanking method cannot meet the "one-size-fits-all" process requirements, and the processing is difficult. The "one-size-fits-all" process requires cutting from one end of the rectangular plate to the other end along a straight line, and dividing it into T...
