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 leveling material between the leveling rollers arranged one above the other are subject to great wear. To reduce this wear, the wear edges of the rulers have previously been welded on with specially selected materials.
  • the rulers were also very expensive because they had to have recesses for the straightening rollers that dipped into them, especially for small diameters.
  • the invention is based on the object of simplifying the lateral support of the straightening material between the straightening rollers.
  • the ruler supports are designed in accordance with claim 2. This enables the ruler supports to be moved into the immediate vicinity of the wear edges. They therefore 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, in this embodiment of the invention it is possible to superimpose an additional bend in the area of the corners of the ruler, which protrude at the longitudinal ends of the rollers between them and, in particular, have the function of centering the leveling material on the inlet side of the rollers.
  • the ruler carrier according to claim 3. This eliminates the need for additional guide rails for the ruler supports.
  • the ruler supports can be provided on the tie rods as bushings with molded claws.
  • Figures 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 and an associated lower part 6, 4 tie rods 7, 8, 9, 10, a roller mill 11 for the concave roller, a roller mill 12 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 seen on the ruler carriers.
  • the ruler carriers 17, 18, 19, 20 or the clamping claws 21, 22, 23, 24 formed thereon extend radially to Workpiece seen, up to 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 slightly 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 x for the convex roller and two guide rulers 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 support 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, so 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 can be so long that they each make up half the overall 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.
  • the ruler plates are pushed in when worn until they can no longer be tensioned with sufficient security. 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 inventive 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 in 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 at its upper end by a not shown, known adjusting screw acc. Arrow 53 adjustable.
  • the ruler 33 with its end face 35 is held on its two longitudinal edges 54, 55 by clamping claws 37, 38. These are pressed by screws 34 and 36 on the ruler support 29.
  • Ruler carrier 29 and ruler 33 are supported from below by a weight compensating 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 clamped in the associated clamps.
  • a workpiece is inserted and the second ruler is finally placed and clamped against the workpiece resting on the first ruler.
  • the concave roller is lowered to the diameter of the workpiece to be machined.
  • the rulers are given the opportunity to open up the gap between them by loosening the ruler supports 17... 20, 29 relative to the tie rods 7.. to adjust the rulers.
  • the method described above has the advantage that the setting of the rulers can be carried out independently of the degree of wear of the rulers.
