Cover the both ends spacing B of 6-1-3k1It is same as Example 4, axle sleeve 6-1-3 wide H1=(Bk1-2B1-h1)/2=40.33mm.
5th to the 7th and three sizing two-wire horizontal roll stands of the first sizing section two roll axle sleeve both ends
Spacing is identical.It is subject to the 5th two roll axle sleeve both ends distance computation.In Fig. 8, the 1st axle sleeve 6-5-3 wide H524mm is taken as,
1st collars 6-5-4 wide C5It is taken as 10mm, is calculated by above-mentioned parameter, θ5=324 °, R5=7.1mm.3rd, 4 lower roll 6-5-6,
The wide B of the roller of 6-5-75=2(R5+C5)=34.2mm, due to Bj1=Bj5=157.49mm, the 1st spacer 6-5-5 wide h5=Bj1-B5=
123.29mm.Due to same unit, the both ends spacing B of two the 1st axle sleeve 6-5-3k5It is same as Example 4, the 1st axle sleeve 6-5-1
Wide H5=(Bk5-2B5-h5)/2=31.19mm.
In Fig. 9,8-1 is the first sizing section edger roll roll shaft, diameter doIt is the edger roll of the first sizing section for φ 25mm, 8-2,
Edger roll bottom diameter DkIt is taken as 80mm, roll gap of the S between two edger roll 8-2 is taken as 2mm, and roll pass radius takes circular pipe blank half
Diameter is RT=6.35mm, 8-3 and 8-4 are respectively the 1st and the 2nd pipe section, SjBetween the 1st and the 2nd pipe section center 8-3,8-4
Away from Sj=Bj1.Edger roll diameter Dn=Dk+2RT- S=90.7mm, it is seen then that be significantly less than Bj1=157.49mm, therefore the first sizing section is vertical
Roller base dislocation arrangement is feasible.
In this example, the molding of circle change side is completed using two asymmetric correction heads, the roll of the asymmetric correction head is four-roller
Arrangement, referring to shown in Figure 10, Figure 11.Roll pass can any angle put, for sake of convenience, here using horizontal direction put
It puts.It as shown in Figure 12 at first of the pass figure in side, is finished product road at square second, as shown in Figure 13 at square second pass figure.
In this example, finished product square tube side length ATIt is 0.5mm, corner radius r in first of pass of Cheng Fang for 10mm, wall thickness t1It is taken as finished product side
Corner of tube radius rT, finished product square tube corner radius rTIt is taken as 1.35t+0.2=0.88mm, r1=rT=0.88mm, asymmetric correction head
Roll shaft diameter dojFor φ 25mm, A is taken1=ATFirst of roll pass arc radius R of -0.76=9.24mm, Cheng FangATake AT1.5
Times, RA=1.5AT=1.5*10mm=15mm, taking tube reducing coefficient μ is 1.01, at corresponding central angle alpha=57.3 of square roll pass circular arc
(μAT-2r1+3.14*r1/2)/RA =37.13 °, the wide a of pass1=2((RA-r1) sin (α/2)+r1cos(α/2)+RA(1-cos
(α/2)))=12.21mm, bottom diameter of the roll DkjIt is taken as 130mm, roller diameter Dj=Dkj+2RA(1-cos (α/2))=131.56mm, side
Distance n=(a of the pipe center O of roll shaft center E to the 1st of roller 3-91+Dkj)/2=71.11mm, side roller 3-9 edge C to the 1st pipe
Distance k=n+D of center Oj/ 2=136.89mm, the distance for vertically moving plate 3-1 edge F to the 1st pipe center O are taken as 130mm,
Turntable 3-3 outer radius Rp with worm gear is taken as 130mm, inside radius rpIt is taken as 80mm, backboard 3-4 short-axis direction edge G to the 1st pipe
The distance m of base center O is taken as 150mm, less than the 1st pipe center O to the distance B of the 2nd pipe 3-11 edge Hm=Bj1-a1/2=
157.49-12.21/2=151.39mm, it can be seen that the asymmetric correction head of two of the arrangement that misplaces will not interact.
In Figure 16~18,9-15 is saw blade, RjFor blade radius, R herejIt is taken as 135mm, 9-16 is the chuck of saw blade, rj
For chuck radius, rjIt is taken as 40mm.1st, the centreline space of the 2nd pipe 9-19,9-20 is away from for Bj1, CjFor the 1st or the 2nd pipe top
The distance to the module top surface of the 1st or the 2nd fixture is held, C is takenjFor 5mm, if saw blade 9-15 central point is Oj, in the 1st pipe 9-19
Heart point is Ej, cross central point OjVertical line be OD, cross EjThe horizontal line of point and the intersection point of vertical line OD are Bj, then in triangle
Shape OjEjBjIn, EjBj=(AT+Bj1)/2, a=Sin-1(EjBj/Rj)=38.34 °,OjBj=RjCosa=105.89mm, chuck 9-16
Minimum point FjO'clock to the 1st or the 2nd fixture highest point AjDistance be AjFJ, as can be seen from Figure 18,
AjFj=OjBj-AjBj-rj=RJcosa-AT-Cj-rj=50.89mm
AjFjValue is all reasonable between 10~70mm.
