Abstract

The utility model relates to a rolling device for cold-rolling precise ultra-narrow steel belts, and comprises a rolling drum, a guide wheel and a drum shaft, wherein internal threads are arranged in a rolling shaft hole of the rolling drum. A screw rod is arranged in the rolling shaft hole of the rolling drum, and the screw rod can be inserted in the rolling shaft hole in a mode of moving right and left. The guide wheel is fixed, so the utility model can solve the stress caused by the side rolling of the steel belt driven by the right and left movement of the guide wheel, and the upper surface of the steel belt has no partial dead streak or bending which can result in the deficiency of final products.

Description

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, steel band is through behind last one milling train, when carrying out reciprocal rolling, generally be by being located at swinging of directive wheel between milling train and the winch spool, realize back and forth twining, when directive wheel swings to the end of both sides, owing to will produce the angle of a maximum between the vertical line of steel band and winch spool axis, 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, from accompanying drawing as can be seen, when the directive wheel side-to-side movement, 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, twisted shape will cause the defective of final products, and serious will cause punching out, cut and to carry out continuously.Therefore, reduce steel band when the extreme position of the left and right sides and the maximum angle between the vertical line of winch spool axis be to overcome the precondition that steel band produces above-mentioned defective.

Summary of the invention

The purpose of this utility model is the wrap-up in a kind of cold rolling accurate super narrow steel strip; Mainly be at the harmful effect of stress, it reduced as far as possible even overcome, thereby obtain quality steel band preferably steel band.

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 winch spool, directive wheel, tube axle, in the coiling axis hole of winch spool, internal thread is set, in the coiling axis hole of described winch spool, a screw rod is set, but described screw rod inserts in the coiling axis hole in the mode of move left and right, and described directive wheel is fixed.

Angle between the axis of the two adjacent steel bands of being reeled on the winch spool is lower than 15 degree, preferably is lower than 10 degree, is preferably lower than 6 degree.Two sides at described winch spool are provided with two baffle plates.

The use the beneficial effects of the utility model are: in the coiling axis hole of winch spool internal thread is set, but a screw rod is inserted the mode that forms 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.

Description of drawings

Accompanying drawing 1 is the schematic diagram of wrap-up described in the utility model;

Accompanying drawing 2 is existing wrap-up schematic diagrames.

The specific embodiment

The steel strip production line of continuous cold rolling, 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.The utility model is disclosed to be wrap-up in a kind of continuous cold rolling accurate super narrow steel strip.

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, inserting roll shaft in the axis hole of winch spool can rotate winch spool 44 thereon freely, above the direction of milling train, a directive wheel 15 is set at winch spool, 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.
