Technical Field
The invention relates to an automatic steel screening method based on stamping blanking width, which is mainly used for automatically screening out the optimal width specification during common material width blanking so as to effectively improve the material utilization rate under quantitative order, thereby reducing the raw material cost and improving the product profit.
Background
In the key stamping process, the existing belt pulley is required to manufacture steel coils into round material sheets through a blanking process before stretching, the material utilization rates of the steel coils with different width specifications for manufacturing the material sheets with different diameters are different, and the material utilization rates caused by the design scheme of manufacturing the steel coils with different diameters in the steel coils with the same specification are also different. According to the blanking rule of the stamping round material sheets, the material utilization rate of the blanking scheme of the round material sheets embedded with each other is highest, in order to reduce the switching frequency of steel coil loading, the rolling material width with the widest specification allowed by equipment in the equipment safety limit is customized, meanwhile, in order to consider that products are blanked under the same material width, the next-stage material width with the widest material width is selected, wherein the blanking width with the width Xi Fang of at least one sheet in the blanking plate is the next-stage material width.
Different products are affected by different blanking diameters to generate the widest material width and the next-stage material width in a plurality of safety limits, but steel factories have the lowest quantitative requirement for the specified material width, and the quantitative requirement is generally greater than 25 tons. When the single product order quantity is smaller than the lowest starting quantity, the single product can only be blanked with other products by sharing the material width, and if the diameter difference of the products is large, the shared material width blanking can cause low utilization rate of partial product materials, so that lean production is not facilitated.
Therefore, on the premise of meeting the demand of the order quantity of the products, the invention provides the automatic screening method for the steel based on the stamping blanking width, which can effectively screen out the optimal blanking width, thereby effectively reducing the cost of raw materials and improving the profit of the products.

s4, calculating to obtain blank weights of products with different numbers according to blanking diameters of the products, and then obtaining raw material weights required by processing the products with different numbers according to order quantities of the products with different numbers, wherein the raw material weights=blank weights x customer order quantities;
s5, obtaining the ton of raw materials required by scrapped products with different numbers in the production process, wherein the ton of raw materials required by scrapped products in the production process=the weight x of raw materials;
s6, obtaining the required total steel amount of all numbered products under different material width specifications, wherein n is the product number to obtain the total steel consumption of all numbered products under the specification of each grade of material width;
and S7, acquiring the material width specification corresponding to the minimum required total steel amount as the blanking material width of the ordered steel according to the required total steel amount of all numbered products under each grade of material width specification.
After step S6 and before step S7, step S6.1 is further included, and the phase difference steel amount of the total required steel amount of all the numbered products under each grade of width specification is obtained, wherein the phase difference steel amount=the maximum value of the total required steel amount-the minimum value of the total required steel amount.
After step S6.1, a further step S6.2 is provided, obtaining the maximum cost savings, said maximum cost savings = steel amount for phase difference x market steel price.
The step S1 is specifically to arrange plates according to the size of a product blanking wafer and the rule of arranging plates in an embedding way, select the maximum material width close to the safety limit of equipment as the widest material width, and select the blanking width of which one piece falls at least from the width Xi Fang in the plate arrangement as the next-stage material width.
