Definitions
- the invention relates to a roller set with at least two deflection rollers for the S-shaped deflection of thin metal strips, in particular metal strips with a strip thickness of up to 1 mm.
- Straightening processes such as tension stretching and stretch bending straightening are known for leveling metal strips. Although these straightening processes are relatively advanced, light center bowls or edge shafts sometimes have to be accepted after leveling. These residual unevenness results from transverse stresses distributed unevenly over the bandwidth, which are superimposed on the tensile stresses in the longitudinal direction of the strip. The smaller the strip thickness and the modulus of elasticity of the metal strip in question, the greater the risk of residual unevenness.
- the invention has for its object to provide a roller set of the embodiment described above, with which in the course of leveling metal strips edge shafts or center bowls can be significantly reduced or eliminated entirely.
- Edge waves or center dishes that exist in the metal strip in question due to the length differences of individual metal strip strips over the strip width can thus be reduced or completely eliminated. Because with a convex outer curvature of the guide roller, the middle of the belt is overstretched and edge waves are eliminated in this way, while with a concave inner curvature of the guide roller, the transverse stresses that otherwise build up from the belt edges towards the center of the belt, i.e. the belt center area is now lengthened like the belt areas, so that center bowls no longer occur. You can always in the middle or edge areas of each Build up higher metal tensile stresses and apply the tensile stresses required for leveling to the strip edge areas as well as the strip center area.
- the two deflection rollers are designed as a tension roller set - with a driven pull roller and brake roller - and between the two deflection rollers a tensile stretch is built in order to level metal strips which are particularly sensitive to surface, for example for lithographic Purposes.
- the aim here is to avoid stretch-bending straightening to level the metal strips in order to avoid surface damage.
- deflecting rollers form two sets of tensioning rollers and a cold rolling mill and / or a stretch-bending leveling mill is arranged between the two tensioning rollers and braking rollers, with at least the one that is immediately upstream and immediately downstream of the cold rolling mill or stretch-bending leveling tower
- Deflection roller has a convex to concave adjustable roller jacket. In these cases, similar effects are achieved in cold rolling and stretch bending straightening as in tension stretching.
- the roller diameter of the adjustable deflection rollers is at least 250 mm, while the wrap angle is at least 90 ° and preferably greater than 150 °.
- the respective deflecting roller with a convex to concave adjustable roller jacket has a pressure chamber arranged between the roller jacket and the roller core with a pressure medium supply for a hydraulic or pneumatic pressure medium, and the concave inner curvature is formed by negative pre-grinding in the depressurized state.
- the pressure medium supply can have an axial rotary feedthrough in one of the two loader pins of the respective deflection roller and the pressure chamber can have a ventilation hole.
- vent hole is only required for the first time filling the pressure chamber with the pressure medium.
- the figures show a set of rollers with at least two deflection rollers 1, 2 for the S-shaped deflection of thin metal strips 3, in particular of metal strips with a strip thickness of up to 1 mm and a strip width of more than 800 mm.
- At least one of the two deflection rollers 1 or 2 has a roller jacket 6 that can be adjusted between a convex outer curvature 4 and a concave inner curvature 5, the respective one Metal strip 3 is guided around the adjustable deflection roller with a wrap angle of at least 90 °, preferably more than 150 °.
- the two deflection rollers 1, 2 can be designed as a tension roller set with a driven pull roller 1 and brake roller 2. In this case, a tensile stretch Z is set up between the two deflection rollers 1, 2.
- deflecting rollers 1, 2, 7, 8 form two sets of tensioning rollers, a cold-rolling stand 9 or a straightening-bending stand 10 being arranged between the two tensioning roller sets 1, 7 and 2, 8 forming brake rollers.
- At least the deflecting roller 1, 2 which is immediately upstream and immediately downstream of the cold rolling stand 9 or the stretch bending stand 10 has a roller jacket 6 which can be adjusted from convex to concave.
- All deflecting rollers 1, 2, 7, 8 or pairs of rollers can always have a roller jacket 6 which can be adjusted from convex to concave.
- the deflection rollers 1, 7 and 2, 8 are arranged vertically one above the other in pairs, according to FIG. 3 arranged horizontally next to one another.
- the roller diameters 1, 2 and 7, 8 of the adjustable deflection rollers are at least 250 mm, so that, taking into account a wrap angle of more than 90 ° and in particular more than 150 °, sufficiently high plastic deformations can be achieved in either the belt edge area or the belt center area.
- FIG. 4 shows a deflection roller 1 with a roller jacket 6 which can be adjusted from convex to concave and which, between the roller jacket 6 and the roller core 11, has a pressure chamber 12 with a pressure medium supply 13 for a hydraulic or pneumatic pressure medium, the concave inner curvature 5 being in a depressurized state is formed by a negative pre-grinding.
- the pressure medium supply 13 has an axial rotary feedthrough 14 in one of the two bearing journals 15 of the respective deflection roller 1 and the pressure chamber 12 has a ventilation hole 16 for the initial filling.
