Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one
See the schematic flow sheet of an embodiment that Fig. 1 shows the screening technique of a kind of blank of the present invention.
As shown in Figure 1, the method includes:
101: obtain the billet size of many assemblies material.
Obtain the dimensional parameters of finished product to be produced, the machined parameters of finished product to be produced, blank limit parameter with
And moulding press parameter；Wherein, dimensional parameters includes: mould direction length L of finished product to be produced, compacting
Direction length W and differently-oriented directivity length H；Machined parameters includes: material skin thickness δ and cutting gap ε；
Blank limits parameter and includes: the mould direction of blank limits length Lx, pressing direction limit length WxWith take
Length H is limited to directionx；Described moulding press parameter includes: orientation cartridge convergence diameter D.
According to preset formula Lp=2 δ+(KL+1) ε+KLL min (0.7D, Lx), Wp=2 δ+(KW+1)
ε+KwW min (0.7D, Wx), Hp=2 δ+(KH+1)ε+KHH min (0.54D, Hx),
Obtain organizing billet size more；
Wherein, LpFor the mould direction length of blank, KLFor blank mold direction can slice number, Wp
The pressing direction length of blank, KWFor blank pressing direction can slice number, HpLong for blank differently-oriented directivity
Degree, KHFor blank differently-oriented directivity can slice number, KL、KWAnd KHFor positive integer.
Such as: existing a collection of finished size is: the product of 29.5 × 5.8 × 9.5 (L × W × H), according to
Known parameters calculates:
The pressing under magnetic field press cartridge convergence diameter D selected is: 200mm；Limit parameter as: 60 × 60
×20(Lx×Wx×Hx)；Material skin thickness δ is: 1.5mm；Cutting gap ε is: 0.35mm.
Due to KL、KWAnd KHFor positive integer, thus obtain
KL=1
LP=32.5mm
Kw=1,2,3,4,5,6,7,8,9
WP=8.8mm；14.95mm；21.1mm；27.25mm；33.4mm；39.55mm；45.7mm；
51.85mm；58mm
KH=1
HP=12.5mm
Thus obtain the slice number of many assemblies material and corresponding billet size according to the above results: 1 × 1
× 1,32.5mm × 8.8mm × 12.5mm；1 × 2 × 1,32.5mm × 14.95mm × 12.5mm；1
× 3 × 1,32.5mm × 21.1mm × 12.5mm；1 × 4 × 1,32.5mm × 27.25mm × 12.5mm；
1 × 5 × 1,32.5mm × 33.4mm × 12.5mm；1 × 6 × 1,32.5mm × 39.55mm × 12.5mm；
1 × 7 × 1,32.5mm × 45.7mm × 12.5mm；1 × 8 × 1,32.5mm × 51.85mm × 12.5mm；
1 × 9 × 1,32.5mm × 58mm × 12.5mm.
102: determine the stock utilization of described many assemblies material according to the billet size of described many assemblies material, go out
Sheet number and/or waste material generation amount.
According to preset formula K=(LHWKLKWKH/LpWpHp) × 100%, calculates the base of each size
Stock utilization K of material；
According to preset formula V1=LpWpHp-WpHpε(KL+ 1)-KL[L Wpε(KH+ 1)]-
KLKH[LHε(KW+ 1)]-LHW KLKWKH, calculate the material skin volume V1 of blank；
According to preset formula V2=WpHpε(KL+1)+KL[L Wpε(KH+1)]+KLKH[LHε
(KW+ 1) the magnetic mud volume V2 of described blank], is calculated；
It should be noted that in the actual course of processing, due to blank material micromicro recycling and
Blank is expected that the follow-up processing procedure of skin is different by different producers, thus blank in the present invention is useless
Material generation amount V=V1+V2 or V=V2.
103: excellent according to the described stock utilization pre-set, described yield rate and/or waste material generation amount
Described many assemblies material is screened by first level, is met the blank of requirement.
The highest according to stock utilization, or waste material generation is minimum, or slice number is the highest, three standard differences
Priority, several preferably blanks before selecting.Assuming according to sequence information, product consumption is very big,
Then the first priority is: slice number is the highest；If this batch of cost of raw material is the highest, then the second priority is:
Waste material produces minimum；Third priority is: stock utilization is the highest.By whole result of calculations through three times
Sequence screening: sequence is according to the first priority for the first time: slice number is the highest, and selects front 20 kinds of arrangement sides
Formula；By these 20 results according to the second priority: waste material produces minimum being ranked up, and selects front 15
Plant arrangement mode, and then to 15 results according to third priority: stock utilization is the highest to be ranked up,
And select first 10 kinds.
It should be noted that in other embodiments of the invention, operator also can be only according to material profit
The highest by rate, or waste material generation is minimum, or blank is entered by any one evaluation criteria of slice Shuo senior middle school
Row filter.
Embodiment two
See Fig. 2 and show that the present invention plants the schematic flow sheet of another embodiment of the screening technique of blank.
In practical operation, the size of the blank mold preserved in die storehouse might not meet requirement, because of
And need the size according to the blank filtered out, and the blank mold in die storehouse is screened further.
201: obtain the billet size of many assemblies material.
202: determine the stock utilization of described many assemblies material according to the billet size of described many assemblies material, go out
Sheet number and/or waste material generation amount.
203: excellent according to the described stock utilization pre-set, described yield rate and/or waste material generation amount
Described many assemblies material is screened by first level, is met the blank of requirement.
The specific operation process of step 201～step 203 and the operation of a upper embodiment in the present embodiment
Process is identical, is not repeating at this.
204: from die storehouse, select size and the size of the blank filtered out blank in preset range
Mould.
205: described blank mold is checked, verify the stock utilization of described blank mold and three
Whether the size of different directions meets preset requirement.
Select to have in outlet from die storehouse and be consistent or one or several of close specification mould, to material profit
Check by rate.The standard of checking is: first, stock utilization >=0.9 × (initial designs level)；
Second, between three different directions sizes, difference is more than 1.0mm, so prevents three directions when post-treatment
Obscure.
