Definitions

  • the invention relates to a cross roll straightening machine, consisting of a formed by a lower yoke, an upper yoke and columns connecting them Frame that receives rotatably mounted rollers in roller mills, the Roll mill of the lower roll in the Unterjoch and the roll mill of an adjusting spindle acted upon upper roller vertically adjustable in the upper yoke and the rollers for setting the crossing angle of the roller axes are pivotally mounted about a vertical center axis.
  • Such an oblique roller straightening machine is, for example, designed by DE 19 10 879 became known.
  • the roller mill For straightening so-called blank material (drawn or peeled Round bars) is the roller mill that supports the lower roller directly from the lower beam supported by the frame.
  • black material unprocessed rolling rods with a not completely round cross-section
  • the piston-cylinder unit on the other hand, can be acted upon with adjustable pressure, with which the Slide the lower roller with the roller mill from the support on the lower beam and the resilient support of the lower roller takes over.
  • the roll or straightening nip can run out of a rod to be straightened Pressure relief of the piston-cylinder unit can be opened.
  • the flexible support provides overload protection.
  • the invention is therefore based on the object in a cross-roll straightening machine the type mentioned above means for guiding the chock to provide for the pillars of the frame, despite the contradictory demands allow both blank material and black material to be straightened.
  • the top roller in one Installation piece is arranged, which is integrated with four guide surfaces between Setting wedges, fitting strips or similar guide means having adjusting means is guided on the columns of the frame, of which on the in the direction of flow of the leveling material seen front and rear frame pillars each Hydraulic guide wedge of a double-acting piston-cylinder unit and the other wedge is mechanically adjustable, and further the chock is formed with a hollow pin for guidance in the Oberjoch is that with a threaded nut for vertical adjustment of the chock is provided by means of a threaded spindle, the adjusting spindle on the upper yoke a double-acting clamping-piston-cylinder unit is assigned.
  • By moving the Wedges are additionally reduced the guide play of the chock to zero mm. In this way, operationally reliable blank material straightening operation can be maintained.
  • the clamping piston-cylinder unit of the adjusting spindle is at maximum pressure and the piston-cylinder units the hydraulic wedges are depressurized. So judging is also of blank material without activated clamping of our management level, i.e. with low set play, possible.
  • the invention offers the possibility of an alternative control such that a straightening gap height set smaller than the current straightening material diameter of the rollers, the tensioning piston-cylinder unit for floating support of the Spindle is loaded and the piston-cylinder units of the hydraulically moved Wedges are depressurized.
  • This allows the requirements for Straightening of black material also create, it is the incoming straightening material by the one set X smaller than the current target diameter Alignment gap height is enabled, the set alignment gap height by the amount X to press because the clamping piston-cylinder unit in the cylinder with a Gap applied according to the way of retreating or evading is.
  • the cylinder can thus "float" around this dimension X and to compensate for the shape deviation of the target diameter.
  • the chock is only subject to mechanical adjustable wedges set by means of stop screws.
  • One according to an embodiment of the invention in the pressure side of the pressure medium supply adjustable pressure relief valve arranged in the clamping piston-cylinder unit ensures that it is possible to avoid the straightening force.
  • a cross-roll straightening machine 1 shown in FIG. 1 has one of four guide columns 2 existing, a lower yoke 3 and an upper yoke 4 connecting Frame.
  • a lower roller 5 is mounted while an upper roller 6 is mounted in a carrier 7, which is from an installation piece 8 is recorded in the guideways 9 formed on the columns 2 is performed (see also Fig. 2).
  • the chock 8 has an engaging in the upper yoke 8 Hollow pin 10 on. This is connected to a threaded nut 11, the for vertical adjustment of the chock 8 and thus setting the Straightening gap between the upper and lower rollers 5, 6 with a screw or threaded spindle 12 cooperates.
  • the chock 8 is - as shown in Fig. 2 - in its the guideways 9 Frame columns 2 facing areas cut out in a V-shape and in these Areas provided with corresponding guide strips 18.
  • the guideways 9 are in mounting blocks 19a to d attached to the frame columns 2 (see FIG. 2). They exist - as can be seen in more detail in FIGS. 5 and 6 is - in the exemplary embodiment, an adjusting wedge 20a or 20b and one complementary, providing the sliding surface for the track strips 18 of the chock 8, counter plate 21 screwed to the mounting blocks 19a to d. Is seen in the direction of passage 22 (see FIG.
  • the piston-cylinder units 23 of the adjusting wedges 20a can thus be adjusted the cross roll straightening machine 1 on the one hand for the blank operation and on the other hand, carry out the black operation.
  • the cylinder piston 25 of the tensioning piston-cylinder unit 15 and of the cylinder piston 26 of the piston-cylinder units 23 are on the clamping piston-cylinder unit 15 and the piston-cylinder units 23 pressure medium lines 27, 28 or 29, 30 connected (cf. FIG. 3 or FIGS. 5 and 7 and 8), connected to a pressure medium source, not shown, and a control unit are.
  • the lines 27, 28 and 29, 30 have an integrated Multi-way valve 31 or 32 on, and to the clamping piston-cylinder unit 15 is in an adjustable pressure relief valve 33 is also provided on the pressure side.
  • the setting wedges 20a become so far via the piston-cylinder units 23 moved until the guide play of the chock 8 in the guideways 9 is reduced to zero, which with the position of the multi-way valve shown in FIG. 7 32 is the case.
  • the blank material thus runs through with a fixed setting Straightening nip rollers 5, 6.
  • the straightening gap height between the rollers 5, 6 set an amount X smaller than the current target diameter.
  • the reversing position is not shown in Fig. 4 - the cylinder piston 25 in the clamping piston-cylinder unit 15 in the intermediate position shown in Fig. 4, in 3 compared to the block position according to FIG. 3, the dimension X of the reduced Alignment gap-high corresponding gap S1 to the block position defined.
  • the cylinder piston 25 can swim to the Compensate the shape deviation of the target diameter.
