Definitions
- Straightening machine for straightening, in particular, the beginning and ends of rolled metal strips or sheet metal strips
- the invention relates to a straightening machine for straightening, in particular, the strip beginnings and ends of rolled metal or sheet metal strips, comprising offset upper and lower, driven straightening rollers which are mounted on the one hand in a base frame and on the other hand in an upper crossbar pivotably articulated thereon.
- the metal strip to be processed in strip systems for cold and hot strip is usually wound up and delivered in coils.
- the tape is then fed into the system from decoilers.
- the curved tape beginnings must be straightened beforehand.
- So-called dressing machines are used for this.
- these have e.g. three to six leveling rollers arranged at the top and bottom of the leveling machine.
- the upper straightening rollers can be adjusted to influence the straightening result, for example by actuators assigned to them and their support rollers, as has become known for a machine of the type mentioned at the beginning by EP 0 060 965 A2.
- the upper crossbar is articulated there via a pivot axis on the base frame.
- the invention has for its object to provide a device of the type mentioned simple and with improved operation.
- the upper crossbar is connected to the base frame via adjusting eccentrics.
- the adjustment eccentrics need to be turned, for example with electric motors, hydraulic cylinders, pneumatic cylinders or comparable actuators, in order to achieve any straightening roller adjustments by changing the inclination and position of the top crossmember. Tilting yoke adjustment in both directions, ie on the inlet or outlet side, is also possible under load.
- the adjustment eccentrics can easily be completely encapsulated and are therefore insensitive to dirt.
- just like their actuators they can be provided remotely from the straightening room, which is therefore free because in this area no other means required for employment are required.
- the scale suction can be designed much better and adapted to the fluidic requirements.
- the good suction ability of the scale is due to a smooth internal structure supports the discharge channels running above and below the upper and lower straightening rollers.
- the adjusting eccentrics are designed as suspension points of the upper crossbeam at both ends of eccentric shafts on the inlet and outlet side.
- These eccentric shafts which extend beyond the width of the straightening machine, provide a total of four suspension points outside the machine, and only one drive is required for each eccentric shaft to adjust the two eccentrics on the inlet and outlet sides.
- An embodiment of the invention provides that the eccentric shafts are arranged in a lower plane than the straightening rollers carried by the base frame, hydraulic cylinders being suspended from the adjusting eccentrics of the eccentric shaft on the inlet side and detachably connected with their shaft-distant ends to the upper cross member and on the adjusting eccentrics of the outlet side Eccentric shaft tension rods are suspended and their shaft-distant ends are mounted in the upper crossbar.
- the adjusting eccentrics or the eccentric shafts thus fulfill a double function, since they also serve as suspension points for articulating the hydraulic cylinders or tie rods.
- the hydraulic cylinders designed as quick-opening cylinders swing the machine open to facilitate the threading process, the eccentric shaft on the outlet side then forming the fulcrum or the axis of rotation.
- a preferred embodiment of the invention provides that the tie rod / upper cross member bearings are coupled to the base frame via tabs.
- the bearings of the upper traverses are arranged in a projecting manner according to the length of the tabs relative to the base frame, which can be used to maintain the machine or to change the straightening rollers.
- be the machine can be opened, namely that the upper crossbar can be adjusted in a vertically erected position about the bearings that then simultaneously represent axes of rotation, so that both the upper straightening rollers and the lower straightening rollers are freely accessible.
- the eccentric shafts are arranged in a higher plane than the straightening rollers carried by the base frame, with hydraulic cylinders suspended from the adjustment eccentrics of the inlet-side eccentric shaft and detachably connected to the upper crossbar, and the adjustment eccentrics of the outlet-side eccentric shaft via tabs with the Base frames are coupled.
- This design in which the pull rods on the outlet side can be omitted, is suitable for straightening thin sheet thicknesses (approx. 2.5 mm).
- the adjustment eccentrics of the outlet-side eccentric shaft arranged in the base frame at the top are also connected to the top crossbar as described above, so that here too, after loosening the inlet-side hydraulic cylinders from the adjustment eccentrics, the top crossbar can be opened or closed, eg with the help of an indoor crane.
- FIG. 1 shows a jig in a side view
- FIG. 2 shows the device according to FIG. 1 in a partially sectioned front view
- FIG. 3 shows the functional principle for straightening roll adjustment by means of an eccentric in a straightening machine according to the figures mentioned above and below;
- FIG. 4 in a simplified side view of a straightening machine shown in Fig. 1, showing the scale suction systems;
- FIG. 5 shows the straightening machine according to FIG. 4 with the upper crossbar folded up
- FIG. 6 shows a schematic drawing of a side view of a jig with top adjustment eccentrics or eccentric shafts.
- the straightening machine 1 has a base frame 3 anchored on a foundation 2 and an upper crossbar 4 articulated thereon and pivotable with it.
- the base frame is provided with three lower straightening rollers 5 and the upper crossbar 4 two upper straightening rollers 6 equipped. Between the lower and upper straightening rollers 5 and 6, the pass line defined in FIG. 1 by a directional arrow 7 indicating the direction of travel for the strip to be straightened from the inlet to the outlet side.
- the upper cross member 4 is suspended from the base frame 3 via an adjusting eccentric 8.
- the adjusting eccentrics 8 are each formed at the two ends of an eccentric shaft 9 or 10 arranged in the base frame 3 both on the inlet side and on the outlet side.
- a geared motor 11 or 12 is connected to each eccentric shaft 9, 10.
- Hydraulic cylinders 13 are located on the adjustment eccentrics 8 of the eccentric shaft 9 on the inlet side and Positioning eccentrics 8 of the eccentric shaft 10 on the outlet side are pull rods 14, the ends of which are removed from the shaft are fastened to the upper cross member 4 via bolt bearings 15.
- the bolt bearings 15 of the pull rods 14 arranged on the outlet side are also coupled to the base frame 4 via double brackets 16 and retaining bolts 17.
- the upper crossbar 4 can also be inclined towards the inlet side, in which case the inlet roller 6a would assume the lower position. This means that positions can be carried out in both directions.
- the straightening machine 1 with eccentric shafts 9, 10 and adjusting eccentrics for the upper cross member 4 is shown in FIG. 4 in the closed operating position clamped against the base frame 3 by means of the hydraulic cylinders 13. Since with the eccentric adjustment the arrangement of the entire adjustment mechanism outside of the straightening space, ie the lower and upper straightening rollers 5, 6 and thus outside of the soiled area is possible, the scale suction consisting of one exhaust pipe 18 and one exhaust duct 19 can be unhindered by otherwise Design the necessary internals according to the fluidic requirements. From FIG. 5 it is also clear that the connection of the upper crossbar 4 by means of upper crossbar bearings 15 as well as tabs 16 and retaining bolts 17 completely open or fold away the Upper crossbar 4 allowed.
- the upper cross member 4 need only be detached from the inlet-side hydraulic cylinders and pivoted into the position shown by, for example, an indoor crane or the like.
- the bolt bearings 15 of the two tie rods 14 represent the pivot axis.
- the pre-straightening machine 1 is thus freely accessible for maintenance and / or for changing the straightening rollers. Roll installation and removal is easy and can be carried out with little effort.
- the inlet-side hydraulic cylinders 13 are separated from the eccentric shaft 9 at symbolically shown coupling points 23, so that the crossbar 4 can then be folded up or down by 180 ° in accordance with the illustration in FIG. 5.
