Definitions
- the invention relates to a Device for straightening metal strips with at least a pair of rollers, between whose rollers the metal band is subjected to stretching or bending, whereby at least one of the rollers of the pair of rollers in the direction of the metal strip is deliverable and the axes of rotation the rollers in the working position offset in two spaced, normal to the main conveying direction of the Metal strip aligned levels are positioned.
- a generic device is e.g. out U.S. Patent No. 4,539,830.
- Known devices usually have at least two straightening units, which of the metal band be run through one after the other.
- the first Straightening unit is the strip, for example, a stretch subject
- the second straightening unit a Bending deformation is carried out.
- the straightening units each have a pair of rollers whose Rotational axes offset in two spaced, normal to Main conveyor direction of the belt aligned levels are positioned so that the tape as it passes the straightening device in each case along a section of the Scope of the roles is performed. Doing so will generate of the stretch train used equally large roles, while the bending tension by combining a large roll with a small role is generated.
- the object of the invention is that Economy of a device of the beginning to improve the type mentioned.
- the invention provides an apparatus that perform two different machining tasks can. In this way the flexibility is such Device increased, which, as a result, also theirs Economy is improved. In such Namely, use cases in which no judging of the Metal strip is required, a rolling mill be performed, and vice versa.
- An inventive Device can therefore be used much more often so that the times when a device according to the invention unused at idle compared to conventional straightening devices are significantly shortened.
- a device according to the invention can also do so be adjusted so that a rolling operation can be carried out can, in which the metal strip through a between the Roll trained nip is passed. Because of the aligned alignment of the axes of rotation of the rollers A common normal plane takes place in this rolling no bending or stretching deformation of the metal strip. This enables the device according to the invention for example, for rolling the metal strip. Such rolling is used in the course of manufacturing a Metal strip carried out if, for example particularly good dimensional stability of the tape is required. In addition, certain things can be done with a skin pass stitch technological properties of the tape set become.
- the one for switching from one to the other This can shorten the operating time required be that the relative position of the rollers by means of Adjusting devices is changeable.
- This Actuators can have their own drive have or operated manually.
- the change of the can be inexpensive and precise relative position of the roles in that the changeable role of one Cross slide drive is worn.
- the invention can be particularly advantageous in Connection with such straightening devices realize in which at least two consecutive of there are pairs of rollers running through the metal strip, which different directional processing of the Perform metal tape.
- the roles of one or both pairs of roles in inventive position relative can be aligned to each other, so by a pair of rollers the strip is rolled, while still by the other pair of roles the strip is straightened.
- the device 1 for straightening or rolling a cold-rolled steel strip S has a frame 2 with a upper and a lower frame half 3.4.
- the Scaffold halves 3, 4 are articulated, so that the framework 2 for inserting the steel strip S or for Maintenance and assembly work by swinging open the upper half of the scaffold 3 can be opened (Fig. 2).
- the scaffold 2 has two processing units 5, 6 arranged, which the steel strip S in its im essentially horizontally aligned Main conveying direction F passes in succession.
- the first processing unit 5 comprises an upper one Holder 7, which carries a cassette 8.
- an upper straightening roller 9 is rotatable on support rollers 10 stored.
- a lower straightening roller 11 is on support rollers 12 rotatably supported in a lower cassette 13.
- the Cassette 13 is on the lower half of the frame 3. Both Cassettes 8, 13 are each in guide elements 14 and 15 so displaceably held that they cross in a directed to the main conveying direction F of the steel strip S. Movement can be pulled out of the scaffold 2.
- the holder 7 is fixed on a table 16 on which it in vertical with the scaffold closed Direction of movement V by means of an automatic Actuator 17 are delivered to the steel belt S. can.
- the table 16 in turn is orthogonal to Direction of movement V of the holder 7 aligned Guideway 18 out on which he by means of a automatic actuator 19 in a parallel to Main conveying direction F of the steel strip S horizontal direction of movement H is displaceable.
- the Table 16, the actuator 17, the guideway 18 and the actuator 19 together form one Cross slide drive for the holder 7 and that of him worn cassette 8.
- the axes of rotation D1, D2 of both straightening rollers 9, 11 are in Operating position offset from each other in two different, normal to the main conveying direction F arranged levels E1, E2 positioned (Fig. 1, Fig. 4).
- the second processing unit 6 comprises one of the upper half of the scaffold 3 worn holder 21, which in a Guide track 22 by means of an automatic actuator 23 in the direction perpendicular to the main conveying direction F.
- Direction of movement V is displaceable.
- the holder 21 carries one transverse to the main conveying direction F from the frame 2 extractable cassette 24 in which an upper Straightening roller 25 is rotatably mounted on support rollers.
- a bending roller 27 is rotatable stored, whose diameter is larger than that Diameter of the straightening roller 25.
- the axis of rotation D3 of the Straightening roller 25 and the axis of rotation D4 of the bending roller 27 are offset from each other in two spaced, normal to Main conveying direction F aligned levels E3, E4 arranged (Fig. 1, Fig. 4).
- the cassettes 8, 13 of the first processing unit 5 can be exchanged for cassettes 30.31.
- cassettes 30.31 In these Cassettes 30, 31 are work rolls 32 and 33, respectively rotatably mounted (Fig. 3).
- first open scaffold 2 (Fig. 2) the beginning of the machining steel strip S passed through the frame 2.
- the first processing unit 5 is with the cassettes 8.13 and the table 16 is in his most distant position from steel strip S.
- the device 1 If the device 1 is to be operated in the pure rolling mode cassettes 8, 13 become the first Treatment device 5 against the cassettes 30.31 the working roles 32,33 exchanged. Is located the holder 7 in its highest raised position. Then the holder 7 on the guideway 18 far in the main conveying direction F of the steel belt S adjusted until the axes of rotation D5, D6 of the work rolls 32.33 together in a direction normal to the conveying direction F aligned level E5. By lowering the Holder 7 is finally the roll gap between the Working roles set 32.33, through which the Steel strip S is pulled. The second processing unit 6 is in its rest position, in which the upper holder 21 in its highest raised Position is set so that no bending deformation of the Steel strip S is carried out (Fig. 3).
- cassettes 8, 13 or 24, 25 of the first and second processing units 5, 6 exchanged for cartridges of the other type be, for example, a different sequence of Achieving directional moves or around a certain directional move double. Can also be taken for granted within the device 1 to the rolling processing in the processing unit 5 a straightening in Connect processing unit 6.
