Wrap-up in the cold rolling accurate super narrow steel strip

Technical field

The utility model relates to the wrap-up in a kind of cold rolling accurate super narrow steel strip.

Background technology

Wrap-up in the steel band of the prior art, in accompanying drawing 2,46 is last one milling train, 44 is winch spool, 15 is directive wheel, accompanying drawing 2b, b ' are the situation of directive wheel at winch spool two side ends, from accompanying drawing as can be seen, when directive wheel moves leftwards and rightwards, steel band will be to a direction warpage, and the stressed meeting in side is introduced harmful stress to steel band, and the introducing of these stress can cause the local dead line and the bending of steel band, the scythe line that these defectives form, the defective that twisted shape will cause final products serious will cause punching out, cut and can't carry out continuously.

Summary of the invention

The purpose of this utility model is to provide the wrap-up in a kind of cold rolling accurate super narrow steel strip, by the move left and right mode of screw rod, can overcome the stress that steel band causes during rolling on winder by directive wheel effectively.

For achieving the above object, the technical solution adopted in the utility model is as follows:

Wrap-up in a kind of cold rolling accurate super narrow steel strip, described wrap-up comprises a support, winch spool, directive wheel, sliding axle, screw rod, described directive wheel is arranged on the top of described winch spool side direction milling train, and be installed on the described support by rotatable, the angle α that forms with respect to milling train during the directive wheel side-to-side movement is less than 25 degree.

Described directive wheel back be provided with a pair of be used on the brush holder support steel band cold-rolling emulsion scrub wheel, and by rotatable rack-mount.Two holes also are set on described support, and wherein a hole is enclosed within on the sliding axle slidably, and another hole can be enclosed within on the screw rod threadably movably.The steel band that comes out in the flat milling train on directive wheel and by two can be in the same way or reverse rotation scrub wheel with between, coil into one on the axle coiling of winch spool and roll up greatly.

The beneficial effects of the utility model are: in the coiling axis hole of winch spool internal thread is set, one screw rod is inserted the mode that formation makes the screw rod move left and right, the stress that so just can solve the side of the steel band that on directive wheel, forms then bring, make the steel band upper surface not have local dead line and bending, cause the defective of final products.

Fig. 2 a is the schematic diagram of wrap-up described in the utility model;

Fig. 2 b, b ' are the state diagram of the directive wheel of existing wrap-up when moving to position, the left and right sides.

The specific embodiment

Below by exemplifying embodiment the utility model is carried out in detail.

The utility model is the wrap-up in the steel strip production line of described continuous cold rolling, this cold-rolled strip production process can be divided into uncoiling, welding, location, level is rolling with vertical rolling, scrub steps such as polishing, roughing, heat treatment, finish rolling, alignment smoothing, rolling, packing.

Owing to need heat treatment through the steel band after the roughing, need deliver to the straight operation of smoothing through the steel band after the finish rolling and coil then, therefore need carry out the rolling in the operation.

As an embodiment of the present utility model, referring to accompanying drawing 1, described winder comprises a winch spool, two sides of winch spool are provided with two baffle plates 19, baffle plate 19 and tube axle can adopt the mode of single coiling to be connected and fixed, inserting roll shaft in the axis hole of winch spool can rotate winch spool 44 thereon freely, above the direction of winch spool side direction milling train, a directive wheel 15 is set, directive wheel 15 back (near winch spool 44 directions) are provided with a pair of wheel 17 of scrubbing, 42, scrub wheel 17, the 42nd, for the cold-rolling emulsion that adheres on the brushing steel band, scrub wheel 17,42 and directive wheel 15 be rotatably installed on the support 40, the parts that dotted line marks in the accompanying drawing 1, two holes also are set on the support 40, one of them is enclosed within on the sliding axle 41 slidably, another can be enclosed within on the screw rod 45 threadably movably, during use, the steel band that comes out in the flat milling train on directive wheel 15 and by two can be in the same way or the scrubbing between the wheel 42 and 17 of reverse rotation, coil into one on the axle coiling of winch spool 44 and roll up greatly.

Wherein, support 40 carries directive wheel 15 and scrubs wheel 17,42 and moves back and forth along sliding axle 41, describedly moves back and forth the internal thread that the positive and negative rotation that relies on screw rod 45 promotes the placement screw hole of support 40 and realizes.

The overall process of rolling has promptly been finished in the rotation rolling that moves back and forth and cooperate the winch spool of winder of directive wheel.

In fact, when aforesaid way is reeled, the steel band side when winch spool two ends are reeled of steel band is changeed, referring to accompanying drawing 2 and in conjunction with the accompanying drawings 1, in accompanying drawing 2,46 is last one milling train, 44 is winch spool, 15 is directive wheel, accompanying drawing 2b, b ' is the situation of directive wheel at winch spool two side ends, as can be seen, when directive wheel moved leftwards and rightwards, steel band will be to a direction warpage from accompanying drawing, the stressed meeting in side is introduced harmful stress to steel band, the introducing of these stress can cause the local dead line and the bending of steel band, the scythe line that these defectives form, twisted shape will cause the defective of final products, and serious will cause punching out, cut and to carry out continuously.

For this reason, one of solution that the present invention proposes is to strengthen winch spool and last distance between the milling train together, referring to accompanying drawing 2, steel band 8 can form a maximum angle α when the directive wheel side-to-side movement, through detecting, the α angle should be less than 45 degree, and preferably less than 25 degree, the best is 15 degree.Angle between the axis of the two adjacent steel bands of being reeled is lower than 15 degree, preferably is lower than 10 degree, is preferably lower than 6 degree.

As another solution of the present invention, referring to accompanying drawing 1,2, the support 40 at directive wheel 15 places is fixing, in the coiling axis hole 18 of winch spool 44, internal thread is set, but a screw rod insert is formed the mode of screw rod move left and right, so just can solve the side of the steel band that on directive wheel, forms in the scheme then the stress that brings, it is emphasized that, angle between the axis of the two adjacent steel bands of being reeled is lower than 15 degree, preferably is lower than 10 degree, is preferably lower than 6 degree.
