Definitions

  • the invention relates to a cross roll straightening machine according to the preamble of claim 1.
  • the guide rulers customary in these machines for lateral support of the straightening material between the straightening rollers arranged one above the other are subject to great wear. To reduce this wear, the wear edges of the rulers were previously welded on with specially selected materials. The rulers were also very complex because they had to have recesses for the straightening rollers dipping into them, especially for small diameters.
  • Such a straightening machine is e.g. known from DE-U No. 6930960. It is shown there that these rulers are fastened to a ruler support which, when the straightening rollers are arranged one above the other, is articulated laterally offset below the lower straightening roller, as seen in the direction of passage of the workpiece.
  • the articulation point of the ruler support is arranged at 45 ° to the vertical, based on the height of the leveling material.
  • the ruler supports there extend from this lower articulation point in the area of the lower part of the straightening machine to the upper part of the straightening machine and are adjustable there. By swiveling the ruler holder, the rulers are set to a different diameter.
  • a straightening press with three straightening tools which, instead of the immovable tools, has inclined concave profiled rotary driven straightening rolls.
  • the support rollers are arranged at both ends of the straightening roller area.
  • Guide rulers are provided between the support rollers.
  • the guide rulers are attached to brackets there.
  • the guide rollers are rotatably mounted on holders, which in turn are adjustable in height on guide columns of the machine frame. Furthermore, the guide rollers can be placed on the workpiece.
  • a cross roll straightening machine with guide rulers is known. They are adjusted by means of set screws that grip the ruler at the back. In the desired position, the ruler is locked in place by clamping screws acting on its two long sides in the area of the rear ruler edge.
  • This type of ruler adjustment has the disadvantage that it only allows a limited adjustment path and a limited length of the rulers. The reason for this is that the rulers are so rigid that the straightening rollers cannot deform them in a suitable way for straightening operation.
  • the rulers have cutouts into which the straightening rollers are immersed. These millings are also designed for a short adjustment range, which essentially corresponds to the wear depth of the ruler faces.
  • a disadvantage of this document is the high processing costs for creating the recesses for the rollers in the rulers.
  • the invention is based on the object of simplifying the lateral support of the straightening material between the straightening rollers.
  • the rigid ruler milled for the straightening rollers is replaced by a non-cutting one.
  • the new ruler is thinner and deformed in such a way that its wear edges correspond to the bending line of the material to be straightened, and it is additionally curved so that there is sufficient free space for the roller sections with the largest diameters.
  • all special measures for a suitable deformation of the ruler are unnecessary.
  • the ruler is pushed between the straightening rollers and deformed by them.
  • the wear between the roller bales lying against the ruler and the ruler is so low that it can be neglected compared to the wear between the target and the ruler.
  • this not only eliminates the welding on the wear edges, but also the milling out for the plunging roller balls.
  • the increased wear that now occurs is compensated for by adjusting the rulers.
  • a hindrance to the deformation of the rulers by the ruler carrier, which is predetermined by the rollers, is avoided in that the two ruler carriers of a ruler can be adjusted independently of one another, i.e. are displaceable or pivotable. Such a hindrance would increase the wear between the rulers and the straightening rollers.
  • the ruler supports can be moved into the immediate vicinity of the wear edges. They thus support the ruler in the immediate vicinity of its stressed wear edge and still allow the ruler to take part in the deformations required by the rollers. Furthermore, it is possible to overlay the ruler with an additional bend in the area of the corners, which protrude at the longitudinal ends of the rolls between them and, in particular, have the function of centering the leveling material on the inlet side of the rolls.
  • the ruler carrier according to claim 2. This eliminates the need for additional guide rails for the ruler supports.
  • the ruler carriers can be provided according to the invention as bushings with molded clamping claws on the tie rods.
  • ruler supports are supported according to claim 3. This makes it possible, after the radial distance between the rulers and the leveling material has been set, to give the ruler the freedom to level itself out by loosening the rulebody's fixations, in order to determine the most favorable position of the ruler carrier and then to fix the ruler carrier in this position lock.
  • FIG. 1 and 2 show a straightening machine 1 with a concave straightening roller 2, a convex straightening roller 3, a rod 4 to be straightened, an upper part 5 of the machine frame, an associated lower part 6, four tie rods 7, 8, 9, 10, a roller mill 11 for the concave roller, a roller mill 12 for the convex roller and two guide rulers 13, 14, between the end faces 15, 16 of which the rod 4 is guided during straightening.
  • the rulers are clamped to ruler supports 17, 18, 19, 20.
  • the ruler supports are slidably guided on the tie rods 7, 8, 9, 10 and supported by springs 40, 41 from below as weight compensation.
  • the rulers 13, 14 are directly attached by means of clamping claws 21, 22, 23, 24 provided on the ruler carriers.
  • the ruler carriers 17, 18, 19, 20 or the clamping claws 21, 22, 23, 24 formed thereon extend radially to Seen workpiece, into the area of the straightening rollers 2, 3.
  • the clamping claws belonging to a ruler When viewed in the direction of the longitudinal extent of the workpiece, the clamping claws belonging to a ruler have a distance that is somewhat larger than a roller length.
  • the rollers 2 and 3 are arranged vertically one above the other.
  • the leveling material is supported on four sides during leveling.
  • the upper and lower supports are provided by the straightening rollers 2, 3;
  • the guide rulers 13, 14 provide lateral support. These four elements form a passage for the leveling material.
  • the springs 40, 41 which support the ruler supports from below, are designed in such a way that the end faces of the rulers automatically level off at about the level of the upper edge of the lower roller 3.
  • the ruler supports 17, 18, 19, 20 with the clamping claws formed thereon are adjustable in height independently of one another. They are locked by clamping levers 42, 43, 44, 45 on the tie rods 7, 8, 9, 10 in the position determined by the straightening rollers 2, 3. It may be advisable to correct the height of the linear corners 51, 52, which protrude on the inlet side between the straightening rollers, such that these corners, in cooperation with the straightening rollers, form an insertion funnel for the straightening material 4. This is made possible by the independent adjustability of the clamping claws 21, 22 of the ruler supports 17, 18 of a ruler 13.
  • the clamping claws 21, 22 always engage on the long sides 56, 57 of the rulers.
  • This enables the use of plastic plates for the rulers.
  • the width of the plates is such that they fit between the clamping claws, and they can be so long that they each account for half the depth of the machine or, if this does not prevent operation, even more.
  • Simple rectangular plastic plates are preferably used which, apart from a clean cut on the end faces 15, 16, require no additional processing. When worn, the ruler plates are pushed in until they can no longer be tensioned with sufficient certainty. Except for the rest mentioned, the entire ruler thus becomes a consumable. By dividing the ruler supports for a ruler, the rollers are more accessible from the operating side 60.
  • the described clamping of the rulers does not prevent the use of conventional steel rulers with welded-on wear edges and recesses for the bale edges 58, 59 of the concave top roller 2. These can be used without further effort.
  • FIG. 3 represents an alternative solution to the example shown in FIGS. 1 and 2 and is provided in particular with existing machines as a possibility for retrofitting to the ruler fastening according to the invention.
  • this straightening machine consists of an upper part 25 and a lower part 26, which are connected to one another by tie rods 27, 28. Between the tie rods extends parallel to it a ruler traverse 30 to which a ruler support 29 is pivotally attached.
  • the ruler support can be adjusted in height by means of an elongated hole 31 in the ruler traverse 30 and a clamping screw 32 guided therein.
  • the ruler traverse is pivotally received on the lower part 26 of the machine frame in bearing blocks 48, 49 by a bolt 50 and is adjustable at its upper end by an adjusting screw (not shown), known per se, according to arrow 53.
  • the ruler 33 with its end face 35 is held on its two longitudinal edges 54, 55 by claws 37, 38. These are pressed against the ruler support 29 by screws 34 and 36.
  • Ruler carrier 29 and ruler 33 are supported from below by a weight balancing hydraulic cylinder 39 to facilitate the higher adjustability. This cylinder is articulated on the ruler support 29 with the aid of fastening tabs 46, 47.
  • the first step in setting up the rulers is to raise the concave roller.
  • a template (not shown) which can be adjusted radially to the workpiece 4 is introduced into the opened nip and is adjusted according to the workpiece diameter provided for the machining.
  • the opposite ruler is placed against this template and in the corresponding one Clamping clamps clamped.
  • a workpiece is inserted and the second ruler is finally positioned and clamped against the workpiece resting on the first ruler.
  • the concave roller is lowered to the diameter of the workpiece to be machined.
  • loosening the ruler supports 17 ... 20, 29 relative to the tie rods 7 ... 10 or relative to the ruler traverse 30 gives the rulers the opportunity to open up the gap between the straightening rollers 2 , 3 to adjust.
  • the procedure described above has the advantage that the setting of the rulers can take place independently of the respective degree of wear of the rulers.
