Description
Technical field
The present invention is the roll gap adjustable flattening machine that is used for metallurgical machinery or other industry straightening plate band.
Background technology
At present, strip material, particularly medium plate (thickness of slab 4-60mm) straightener is permanent roll spacing or two permanent roll spacing straightener both at home and abroad, does not also find the reported in literature with the present invention's same or analogous plate and band material roll gap adjustable flattening machine on principle and structure.The shortcoming that permanent roll spacing straightener exists is: roll spacing can not change with the thickness and the Strength Changes of straightening plate band, like this, it or not the strength weak of roller system and transmission device, the thickness and the intensity that are exactly the straightening plate band are restricted, the straightening capacity of straightener can not be given full play of, and the strip material that two straighteners are aligned the different-thickness scope perhaps is installed.
Summary of the invention
The theoretical foundation of plate and band material roll gap adjustable flattening machine is according to gaugger power energy parameter calculation formula (Zou Jiaxiang of the rolling machinery University of Science ﹠ Technology, Beijing chief editor metallurgical industry 2000.P372 of publishing house), supposes:
1) bending moment of rolled piece is plastic bending moment, i.e. M under 2,3,4 rollers
2=M
3=M
4=Ms;
2) n-
1, n-
2, n-
3The bending moment of rolled piece is yield moment Mw, i.e. Mn-under the roller
1=Mn-
2=Mn-
3=Mw;
3) bending moment of rolled piece is the mean value of yield moment Mw and plastic bending moment Ms, i.e. M under all the other each rollers
5=M
6=...=Mn-
4=(Ms+Mw)/2
4) straight roller quantity n=
9, (or n=
11, last 6, down 5, or n=
11, last 5, down 6, or n=
9, last 4, down 5, or n=
9, last 5, down 4, or n=
7, last 4, down 3, or n=
7, last 3, down 4, or n 〉=5) and the computing formula of corrective force is under each roller:
P＝2Ms/t P
2＝6Ms/t P
3＝8Ms/t
P
4＝(7Ms+Mw)/t P
5＝(5Ms+3Mw)/t P
6＝(Ms+7Mw)/t
P
7＝8Mw/t P
8＝6Mw/t P
9＝2Ms/t
Wherein, the 3rd roller corrective force is a maximum.
The corrective force that last row's roller or lower roll are subjected to is:
∑ P
On=∑ P
Down=2 (Ms+Mw) (n-2)/t
In the formula: t is the aligning roll gap
Ms＝σ
s?bhh/4
Mw＝σ
s?bhh/6
σ
sBe the steel plate yield limit, h is a steel plate thickness, and b is a steel plate width.
From above formula as can be seen, when a straightening steel plate size and performance (yield limit) timing, the corrective force that acts on the smoothing roll is inversely proportional to aligning roll gap t, and promptly roll gap is big more, and corrective force is more little.Minimum roll spacing tmin is limited by roller torsional strength and body of roll contact stress, can be determined by strength calculation formula.Usually, only strip thickness is just checked maximum roll spacing tmax condition less than the arbor press of 4mm.Because result of calculation shows, as hmin during greater than 4mm, the tmax value is far longer than the tmin value that calculates by strength condition, and the t value should be chosen near the tmin value.
The present invention designs a kind of strip material, particularly medium plate roll gap adjustable flattening machine according to the above-mentioned theory basis, thereby has overcome the shortcoming that permanent roll spacing straightener exists effectively.
Technical solution of the present invention: comprise main motor, reductor, gear distribution box, universal-joint spindle, straightening machine body, entrance pinch roll, outlet pinch roll, changing rig, straightening machine body comprises frame, last roller arrangement, goes up walking beam, descends roller arrangement, top roll depress oil cylinder, balancing cylinder, rotary bracket.Promptly in last roller arrangement and following roller arrangement, be separately installed with motor, worm and wormwheel reductor, screw mandrel, nut, under the backing roll assembly axis bearing in the straightening roller device wedge is installed, smoothing roll quantity is more than or equal to five, being staggered up and down arranges, upper entrance side and outlet side, transmission side and the changing side of last roller arrangement are separately installed with depress oil cylinder, and the rotary bracket of band hydraulic cylinder is installed on the transmission side frame.
Described two ends of going up the straightening roller device in roller arrangement and the following roller arrangement have the seam of adjustable clearance, connect with top roll frame and lower roll frame.
Between the described straightening roller device of going up in roller arrangement and the following roller arrangement hydraulic die cushion is installed.
Be equipped with in the described down roller arrangement compress roller arrangement compress the roller oil cylinder.
Described every smoothing roll is equipped with many row's backing rolls, under the every back-up chock wedge is installed.
Described frame has transmission side frame, changing side frame, entablature, sill, and transmission side frame and changing side frame also can be combination prefastening frame.
Described rotary bracket supporting universal-joint spindle and location, rotary bracket is equipped with hydraulic cylinder, and changing rig is equipped with motor, reductor, hydraulic cylinder.
Described straightener is equipped with one or more main motor and speed reducer, gear distribution box.
Be separately installed with hydraulic cylinder between the up-down rollers of described entrance side pinch roll and outlet side pinch roll, the transmission side of down roller is separately installed with motor, reductor, and the bottom is equipped with motor, reductor, screw mandrel jack.
Advantage of the present invention: owing to taked abovementioned technology, it is strong to make the present invention have rectification plate band ability, be rectification plate thickness of strip wide ranges, intensity height, the technology of the present invention is installed a straightener and just can be satisfied present cut deal steel rolling mill and produce the wide requirement with high-strength steel sheet of steel plate thickness range.If permanent roll spacing straightener is changed into this kind roll gap adjustable flattening machine, the ability of straightening steel plate improves a lot.Fascinating and the steel plate of the rectifiable defective of roller function of smoothing roll at different parts; Wedge under the back-up chock can guarantee that backing roll contacts with smoothing roll well, and is stressed even, the service life of improving smoothing roll and backing roll and bearing; Rotary bracket is convenient to the maintenance between smoothing roll and the universal-joint spindle; Changing rig realized changing fast advantages such as straightening roller device in about 30 minutes.
Technical performance contrast (seeing Table 1) after cut deal permanent roll spacing straightener technical performance and the use present technique change roll spacing both at home and abroad.
