Embodiment ( 1
[0261] Example (1): Bar material blanking
[0262] Fill in the calculation parameters of bar blanking as shown in Table 1.
[0263] Table 1 Bar blanking calculation parameters
[0264]
[0265] The production quantity is 200 pieces. The blank blanking results are as follows:
[0266] "Saw: 250.00-4 pieces; 99.50-1 piece".
[0267] After verification and calculation, the blank blanking result of the system is correct.
[0268] Reference Image 6 , The system automatically fills in the content and requirements of the blanking process (step), and indicates the remarks in it.
Embodiment ( 2
[0269] Example (2): Single sheet size blanking
[0270] Fill in the blanking calculation parameters as shown in Table 2.
[0271] Table 2 Blanking calculation parameters
[0272]
[0273] The production quantity is 12 pieces. The blank blanking results are as follows:
[0274] "Cut: 2371.00×1145.00-2 pieces (3×2)".
[0275] After verification and calculation, the blank blanking result of the system is correct.
[0276] Reference Figure 7 , The system automatically fills in the content and requirements of the blanking process (step), and indicates the remarks in it.
Embodiment ( 3
[0277] Embodiment (three): two kinds of sheet material specifications blanking
[0278] The calculation parameters of the combined blank blanking are shown in Table 3.
[0281] The production quantity is 20 pieces. The blank blanking results are as follows:
[0282] "Cut: 1853.00×1440.00-2 pieces (10×2)".
[0283] After verification and calculation, the blank blanking result of the system is correct.
[0284] Reference Picture 8 , The system automatically fills in the content and requirements of the blanking process (step), and indicates the remarks in it.
[0285] In short, the present invention first fills in the corresponding blanking parameters in the process card; then according to the product production set quantity given in the processing task sheet, the production quantity of the parts is determined by the number of parts in the manufacturing bill of materials; then the calculation formula is used , Boundary condit...

Abstract
The invention discloses an intelligent blanking size calculation system for various types of multiple part blanks, and belongs to the technical field of advanced manufacturing. The system mainly comprises a blanking parameter setting module and a blanking scheme generating module. The working mode of the system is as follows: firstly, corresponding blanking parameters are filled in a technologicalprocess card; then, according to the given product production suite in the machining task list, the part production quantity is determined through the part loading quantity in the manufacturing material list; parameters and part production quantity are calculated by utilizing a calculation formula and boundary conditions; the size and the using amount of blanks required for processing a certain number of parts are automatically calculated at a background, blanking optimization calculation of three blank types including roots, discs and plates is realized, scoring evaluation is finally performed according to a calculation result, and optimal overall blanking scheme data is output. According to the method, the purposes of machining process preposition and process solidification can be achieved, the production efficiency is improved, the production cost is reduced, and the economic benefits of enterprises are improved.
Description
Technical field [0001] The present invention relates to the field of advanced manufacturing technology, in particular to an intelligent blanking size calculation system for multiple types and multiple parts blanks. Background technique [0002] At the national level, my country’s overall strategy to build a manufacturing power has been determined, and it is clearly stated that the new generation of information technology and the deep integration of the manufacturing industry should be the main line, the promotion of intelligent manufacturing as the main attack direction, and the historical leap of manufacturing from large to strong. In the field of machinery manufacturing, blanking is the first process in product production, and it is also a key process that affects production and product quality. However, the traditional cutting production process still has many shortcomings in many aspects. [0003] In the calculation of blanking data, it mainly relies on manual calculation mode...
