The span ratio of machine is between 0.85 to 0.9.
Sheet metal is acted on during being bitten by upper roller by too much force, as shown in Figure 4.Wherein lower roll is applied with
One frictional force F forwardxSheet metal is driven to travel forward, when sheet metal touches upper roller, upper roller is to sheet metal
A resistance N obliquely is generated, while in the presence of resistance N, upper roller is generated perpendicular to N obliquely with sheet metal
The frictional force P for promoting copper starting sheet to travel forward, these three power will constitute a mechanical relationship, only when frictional force P is in level
The power P in directionxWith frictional force FxMake a concerted effort be more than the resistance N of N in the horizontal directionxWhen, sheet metal could smoothly bite upper roller.
I.e.：Fx+Px≥Nx(1)
The F in formula (1)x=μ F=μ (Nx+Px)=μ (Ncos α+μ Nsin α), Nx=Nsin α and Px=Pcos α=μ
α in Ncos α, these formulas is resistance N and the angle of vertical direction, and above-mentioned formula is substituted into formula (1) to obtain：
2μcosα+(μ2-1)sinα≥0
(2)
Friction coefficient μ=0.2 of the copper to steel rider can be checked according to mechanical design handbook, may be used also according to trigonometric function relation
Try to achieve cos α=(R-e)/R, sin α=(2Re-e2)1/2/ R, wherein R are D/2 for the radius of roller, and e represents roller drafts
Maximum, above equation is substituted into formula (2) and obtained：
R2-13.52Re+6.76e2≥0
(3)
To formula (3) carry out solution can obtain R≤0.52e or R >=13e, due to R can neither too it is small can not be negative, institute
To take R >=13e to be calculated.Only when the original curvature of sheet metal is zero or the amount of deflection direction of original curvature and press-bending side
To it is identical when, roller is only possible to produce maximum defluxion to the volume under pressure that sheet metal applies, and its value is：
According to twice and p=2l that the maximum of upper roller volume under pressure is maximum deflection amount of deflection, with reference to formula：
It can obtain：
Formula (6) is substituted into D/2=p β/2=R >=13e, obtained：
Wherein：The elastic modulus E of fine copper is 108Gpa, the yield limit intensity σ of coppersFor 69Mpa, span is 0.9 than β,
Therefore the maximum of roll spacing can be calculated：
pmax=73H (8)
Due to span ratioRoll spacing maximum according to trying to achieve can obtain roll neck maximum：
Dmax=65H
(9)
By the analysis and calculating to roller bite condition, the maximum of roller diameter and roll spacing is obtained, but now calculate
Data out can only meet the condition that copper sheet can be bitten by roller, not have also for the fatigue pitting for how reducing copper sheet
Analysis, it is therefore desirable to the diameter of roller is limited with the contact strength of roller and copper sheet, the minimum value of roll neck is further tried to achieve.
With limit contact stress [σ] for standard, if the maximum σ of copper sheet and roller contact stressmaxConnect less than the limit
Touch stress, then degrade ability of the copper sheet during essence is rectified will be very low, and some protective effects can be played to roller,
I.e.：
During essence is rectified, because the material of smoothing roll is steel, the hardness of steel is more much higher than the hardness of copper, therefore should
Using the yield strength of copper sheet as measurement foundation, the numerical value for making limit contact stress is twice of copper sheet yield limit intensity,
That is the σ of [σ]=2s=138Mpa.
In formula (10), F is the maximum straightening force (maximum according to the straightening force that Fig. 4 can set the second roller) of upper roller, according to
According to formula：
F=8M can be obtainedmax/ p, the maximum aligning moment of flexure of the second roller can be by formulaObtain, it may thus be appreciated thatWherein Mw=Zwσs, being arranged by formula (11) to obtain：
Z in formula (12)wFor the elastic section modulus of rectangle, its value is BH2/ 6, modeling is curved to compare maximumIts value takes
1.5, the elastic modulus E of fine copper is 108Gpa, the yield limit intensity σ of coppersFor 69Mpa, span is 0.9 than β value, by more than
Numerical value is brought into inequality (12), can obtain the minimum value of roll neck：
According to span than β=0.9, it can show that minimum roll spacing is：
pmin=Dmin/ β=18H
(14)
By the research of the strong mechanical characteristic of pair roller type straightener essence, can upper roller be bitten as condition using copper sheet, analysis is stung
The stress of fashionable copper sheet, obtains the maximum gauge of roller and maximum roll spacing, then strong when being contacted with copper sheet with upper roller
Degree is constraint no more than the limit contact strength of copper sheet, calculates roll neck and the minimum value of roll spacing, finally tries to achieve roll spacing p's
Span is 18H≤p≤73H, and roll neck D span is 16H≤D≤65H.
The arrangement of the strong roller of essence, using upper row's roller is adjustable, lower roll is fixed, this arrangement only needs to the row's of calculating roller
Bent mirror, without seeking the Bent mirror of lower roll, the drafts of the namely upper row's roller of Bent mirror.
During whole essence is rectified, the residual curvature of copper sheet numerically absolutely not exceedes the elastic curvature pole of copper sheet
Limit.In this case, the press-bending curvature of copper sheet compares CwWith Bending Deflection ratioBe it is equal, i.e.,：
Before the strong roller Bent mirror of each essence is calculated, the Bending Deflection of each roller should be first calculated：
According to formula (16), the Bending Deflection to obtain each roller just must first obtain the elastic limit of copper sheet
Amount of deflection：
P in formula (17) is roll spacing, is 18H≤p≤73H above having tried to achieve its scope, further according to copper sheet
Thickness H=0.8mm, therefore 14.4mm≤p≤58.4mm can be obtained, it is 108Gpa, the yield limit of copper by the elastic modulus E of fine copper
Intensity σsFor 69Mpa, the elastic limit amount of deflection of copper sheet can be finally tried to achieve.
Therefore, the calculation formula of the Bent mirror of upper row's roller (in addition to the second roller and the (n-1)th roller) is：
The calculation formula of second roller Bent mirror is：δ2=2 δw2
(19)
The calculation formula of (n-1)th roller Bent mirror is：δn-1=2 δw(n-1)
(20)
Wherein, i numbers for roller, and the numbering of upper row's roller is (2), (4), (6), (8), (10), the numbering of lower roll
For (1), (3), (5), (7), (9), (11), n is 11 for the sum of roller.
It is p=20mm, p=30mm, p=40mm, p=50mm to take roll spacing respectively, according to the numerical value of these roll spacings, obtains copper
The elastic limit amount of deflection of thin plate, then the Bending Deflection of each roller is obtained, it can finally try to achieve the Bent mirror of the strong roller of each essence, you can
