Definitions
- the invention relates to a device for strip processing with at least one unwinding station, at least one band processing station and at least one coiling station, wherein between the unwinding station and the coiling station a band edge of the band stretching band edge stretching station is provided. Furthermore, the invention relates to a method for strip processing.
- the strip processing involves trimming a strip
- the strip is unwound from a coil in an uncoiling station, fed to the trimming station, trimmed in the trimming station by a trimming knife, and then reeled from a coiling station onto a coil.
- generic devices for strip processing are also used for sharing, cold rolling or the like.
- this strip is usually subjected to a plurality of rolling passes. Over the greater part of the width of the strip, the decrease in thickness during rolling leads to an increase in the length of the strip. In the area of the strip edges, however, besides the effect of increasing the strip length during rolling, the bandwidth increase occurs. Due to the increase in the width of the tape at the edge of the tape is less material for the Increase in the tape length at the edge of the tape available, resulting in that in the band a more or less high band edge tension arises. The band edge tension described leads to various problems in the further band processing.
- a high strip edge tension during the rolling process means that a higher roll energy must be applied to overcome the strip edge tension at each roll pass than would be necessary if the strip edge tension were completely removed. If the strip edge tension can therefore be reduced between two rolling passes, the required roll energy is reduced during the second pass.
- US Pat. No. 3,854,315 discloses an apparatus for trimming or leveling elongated metal strips of different widths, in which strips of a plurality of different widths can be machined, the setting of the device being carried out by hand, which is very expensive. Another disadvantage is that in this device it is not possible to optimally take into account the voltage profiles in the band edge. Furthermore, due to the large dimensions of this device, a lot of space is needed to set up the device.
- the present invention has the object to provide a device for tape processing available, which has small dimensions, is easily adjustable and beyond a targeted, depending on the distance from the band edges stretching allowed.
- the band edge stretching station has two laterally engaging in the band band edge stretching units and a strip edge stretching unit each having at least three Bandkantenumlenkrollen, the Bandkantenumlenkrollen substantially perpendicular to the band plane are mutually adjustable, the Bandkantenumlenkrollen frusto-conical are and the band edge stretching units are arranged displaceably in the band plane perpendicular to the strip running direction.
- the Bandkantenumlenkrollen are mutually adjustable substantially perpendicular to the belt plane, the enforced via the Bandkantenumlenkrollen loop can be adjusted, which in turn the degree of stretching is adjustable.
- the frusto-conical configuration of the band edge deflection rollers simplifies the threading of the band edges between the band edge deflection rollers and ensures that an increasing stretching takes place toward the edge of the band, thereby taking into account the stress gradient in the band edge.
- Other thickness profiles for the band edge deflection rollers are also conceivable which are each adapted to the desired stretching course.
- the strip edge stretching devices are arranged displaceably in the strip plane perpendicular to the strip running direction, the depth of insertion of the strip edge deflection rolls can be adjusted into the strip and thus the area of the strip edges which is stretched can vary.
- the strip processing device according to the invention is particularly suitable for processing strips of aluminum materials, since due to the work hardening properties of aluminum during cold rolling of aluminum strips, particularly high strip edge stresses occur.
- the strip processing can consist in particular exclusively in stretching the strip edges of the strip.
- a strip edge stretching station would be, for example, subjecting the strip edges to a separate rolling pass, which preferably does not involve processing of the strip between the strip edges. It is conceivable, for example, the arrangement of two short rollers in the region of the strip edges, which specifically roll, for example, in cooperation with a deflection roller in the rolling mill, the strip edges, whereby the strip edge stresses are reduced.
- an embodiment of the device according to the invention for strip processing has proved to be particularly advantageous in which the strip edge stretching station has two strip edge stretching units engaging laterally in the strip and a strip edge stretching unit has at least three strip edge deflection rolls.
- the belt edges are stretched by not passing straight in the belt transporting direction between the belt edge deflection rollers, but being looped over the belt edge deflection rollers which result in stretching of the belt edges due to path extension for the belt edges.
- Such a band edge stretching station is very constructive simple and easy to integrate into existing tape processing equipment.
- the invention also relates to a method of tape processing in which the tape is unwound from a coil and reeled on a coil in a coiling station, the tape edges of the tape being stretched between the uncoiling station and the coiling station in a band edge stretching station. using a device described above.
- the band edges of the band arranged in each case over at least three perpendicular to the belt plane, displaceable perpendicular to the strip running direction, each laterally engaging in the band strip edge stretching units of a Bandkantenreckstation, mutually adjustable, frustoconical Band edge deflection rollers are guided in a variable-size adjustable loop, wherein the stretched area of the strip edges is adjusted via a displacement of the strip edge stretching units perpendicular to the strip running direction and wherein the strip is stretched towards the edge stronger.
- Fig. 1 of a device according to the invention for strip processing shows neither a Abhaspel- still a Aufhaspelstation, the construction of which, however, is known per se.
- a band processing station among other things, a roller cutter 1 for trimming a belt, not shown, is shown.
- the band edge stretching station 2 has two laterally in the not shown band engaging strip edge stretching units 3, wherein each of the strip edge stretching units 3 each have three, in Fig. 1 only partially visible, Bandkantenumlenkrollen 4 has.
- Fig. 1 it is further shown that the band edge stretching units are slidably mounted on guides 5 in the band plane, perpendicular to the strip running direction.
- the displacement of the hand edge stretching unit en 3 on the guides 5 is done manually.
- a strip edge stretching unit 3 is shown in an enlarged perspective view. It can be seen in Fig. 2 particularly clearly the three Bandkantenumlenkrollen 4, the roller shafts 6 and partially a guide 5. From the illustration in Fig. 3 it can be seen that the uppermost of the Bandkantenumlenkrollen 4 via an adjusting screw 7 in its immersion depth with respect to the lower of the Bandkantenumlenkrollen 4, that is perpendicular to the band plane, is adjustable. About this immersion depth, the loop is set in which the band 8 shown in phantom in Fig. 3 by the band edge stretching unit 3 runs.
- the Bandkantenumlenkrollen 4 are frusto-conical, resulting in a different degree of stretching of the strip edge in dependence on the distance from the edge of the strip.
- the Band edge deflection rollers 4 are preferably mounted on two bearings 9 relative to the roller shaft 6 to accommodate the not inconsiderable radial forces during belt transport.
