Abstract
The invention discloses a numerical control batch nesting method for small parts. The method comprises the following steps: 1, splicing multiple small parts into a large part in graphics software, and taking the overlapped edges of the small parts as spraying lines of the large part; 2, warehousing and nesting multiple large parts into an overall pattern, and cutting the overall pattern to obtain multiple independent large parts with spraying lines; 3, cutting each large part into multiple independent small parts along the spraying lines. According to the numerical control batch nesting method for the small parts, a manner of combining the multiple small parts into the large parts and warehousing and nesting the large parts into the overall pattern is adopted, so that the nesting time is shortened, and the working efficiency is improved; a numerical control cutting machine is only started and stopped once for cutting a large part, so that cutting nozzle loss is reduced, and the cutting time is shortened; the large parts are cut into the multiple small parts, so that the cost is reduced, and the cutting efficiency and the cutting quality are improved.
Description
Technical field
The present invention relates to CNC cutting field, be specifically related to the numerical control nesting method of a kind of batch finding.
Background technology
Although Ship Structure belongs to Large Steel body structure, but still suffering from the findings such as large quantities of connector, reinforcement and stiffener in design, and these findings are except being partially installed on molded line position, other is all general part.In traditional jacking technology, need during jacking between part and part, retain certain cutting gap, as the loss compensated when cutting, owing in Ship Structure, small dimension number of parts is many, one jacking card is likely to there are hundreds and thousands of parts, one by one each part is touched by (adjust part gap) and adjusted and cut striking point, taking time and effort, jacking efficiency is low, is also unfavorable for the raising of availability ratio of the armor plate.Additionally, due to numerical control cutting machine often cuts a part, being necessary for igniting striking, blow-out once, igniting striking and blow-out greatly increase the loss of cutting torch frequently, and cut quality is also poor, and rework rate is higher.
In order to solve the problems referred to above, people begin to use nesting method to carry out Numerical control cutting part.If publication number is the Chinese invention patent application of CN1954953A, the method disclosing CNC cutting cutting parts, it it is the outline according to each part arranged on sheet material, cut along part edge, after cutting one section along a part edge, it is transitioned into the part edge cutting of this arranged adjacent in the position suitable with the part edge of arranged adjacent, carries out continuous print cutting by that analogy, finally cut all of part edge continuously.The part edge tangency location of arranged adjacent or the close position of comparison carry out transition.Cutting in all part edges, running into when having groove line segment, cutting head is turned to the state of inclination, completes the cutting of groove line segment.Although the method can save consumptive material, reduce and pollute, improve cut quality, but cutting efficiency is low, is unsuitable for the making of part volume.
Summary of the invention
In view of this, it is necessary to for above-mentioned problem, it is provided that the numerical control nesting method of a kind of batch finding.
In order to achieve the above object, the present invention adopts the following technical scheme that and realizes:
A kind of batch finding numerical control nesting method, comprises the steps:
S1, multiple findings piecing together in graphics software a big part, the coincidence limit of finding is as the spray line of big part；
S2, multiple big parts are put in storage jacking becoming an overall pattern, cutting machine carries out spray line and cutting obtains multiple independent big part with spray line；
Each big part is cut into multiple independent finding by S3, edge spray line.
Preferably, in step S1, multiple findings are single pieces together a big part.The coincidence limit of finding is as the spray line of big part, it is simple to follow-up shearing, improves shear efficiency.
Preferably, in each big part, the shape of multiple findings is identical.
Preferably, in each big part, the shape of multiple findings differs.
Preferably, in step S2, multiple big parts warehouse-in jacking becomes an overall pattern.
Preferably, in overall pattern, the shape of multiple big parts is identical.
Preferably, in overall pattern, the shape of multiple big parts differs.
Preferably, the graphics software described in step S1 is CAD software.
Preferably, step S2 use cutting machine carry out spray line and cutting.
Preferably, step S3 use cutter shear.
Compared with prior art, the numerical control nesting method of present invention batch finding, have several advantages that
(1) further put the mode of the integral pattern of jacking in storage by multiple findings being merged into a big part, shorten the time of jacking, improve work efficiency；
(2) quantity of the big part merged in the quantity of the finding of merging, overall pattern in each big part can be determined according to the sum of required finding and sheet material size, can make full use of sheet material, to improve availability ratio of the armor plate；
(3) often one big part of cutting is just struck sparks, is stopped working once, reduces the loss of cutting torch, decreases clipping time, and big part obtains multiple finding by shearing, reduces cost, improves cutting efficiency and cut quality.

Detailed description of the invention
In order to better illustrate the present invention, it is described further below in conjunction with the drawings and specific embodiments.Jacking after the warehouse-in related in the present embodiment belongs to existing mature technology, and therefore it does not do in the present embodiment too much description.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of batch finding numerical control nesting method, comprise the steps:
S1, piecing together a big part 2 by single for the finding 4 of multiple same shapes in CAD software, mark the profile of each finding 4 on big part 2, the coincidence limit of finding 4 is as the spray line 3 of big part 2；
S2, the big part 2 of multiple same shapes is put in storage jacking becoming an overall pattern, multiple big parts 2 are arranged side by side on steel plate 1, use cutting machine to obtain multiple independent big part with spray line after carrying out spray line, cutting；
Each big part 2 is cut into multiple independent finding 4 along spray line 3 by S3, use cutter.
Embodiment 2
As shown in figs. 1 and 3, a kind of batch finding numerical control nesting method, comprise the steps:
