Definitions

  • the present invention relates to a device for straightening metallic material according to the preamble of claim 1 (see eg US-A-2008/0011036 ), also referred to as straightening machine, wherein the metallic material is moved in operation from an inlet side of the device to an outlet side.
  • Such devices have been known in metalworking for many years. They comprise an upper set of straightening rollers and a lower set of straightening rollers, each having an edge straightening roller on the inlet side and the outlet side, the upper and lower straightening rollers being offset from one another and a plurality of upper and lower drive shafts , which serve to drive the straightening rollers. Further, a plurality of lower Stauerrollenböcken is provided, each having a plurality of support rollers, which serve to support the lower straightening rollers and are arranged in rows, with their axes parallel to the axes of the straightening rollers.
  • a targeted override is desired. This is an optional direction of material curvature.
  • the present invention is therefore an object of the invention to provide a device for straightening metallic material, in which the above Disadvantages are avoided and in particular a minimum distance between the straightening rollers can be achieved.
  • At least one of the lower edge straightening rollers of the lower straightening roller set of the straightening device is arranged individually adjustable, wherein it is mounted on both sides in a rocker whose axis of rotation coincides with the axis of rotation of those support roller, which is located immediately adjacent to the peripheral support roller that the edge side Support rollers, which are associated with the at least one edge-side movable lower straightening roller and which form a support roller row are movable, and that means for synchronously moving the edge-side support rollers are provided, wherein at least one of the lower edge straightening rollers follows this movement, it is achieved that a in Substantially the same small distance between the at least one edge-side lower straightening roller and the adjacent straightening roller, as in the rest of the straightening roller set, is made possible, which leads to a particularly good and easily adjustable result.
  • the means for moving the associated support roller has a longitudinally movable carriage per movable support roller of each support roller block. By such a slide a simple displacement possibility of the support roller is created.
  • the moving edge-side support rollers have a smaller diameter than the remaining support rollers of the support roller blocks, whereby a correspondingly compact design of the entire straightening unit can be maintained.
  • the rocker is connected to a receptacle for holding the last lower drive shaft, whereby when removing or replacing the straightening roller, the drive shaft can be held and does not fall down.
  • the movement of the carriage is horizontal. This further contributes to the compact design of the entire device.
  • the means for synchronously moving the peripheral support rollers on an actuator and the actuator can advantageously be formed of a hydraulic cylinder, a screw jack or a spindle drive.
  • the actuator acts only from the edge in the direction of set of straightening, so only in an effect and the means for synchronously moving the peripheral support rollers in Absenkides the edge straightening roller acted upon by a spring means, whereby a retraction of the actuating drive, the support roller together with the Carriage is pushed away from the adjacent support roller.
  • a bar or a yoke is provided between the actuator and slide for power transmission and thus can be done in a simple manner a power transmission from the actuator to all slides.
  • each rocker which supports the lower edge-side straightening roller, is pivotally mounted in a lateral bearing strip.
  • the adjustable lower edge-side straightening roller can be arranged on the outlet side and / or on the inlet side of the straightening device. On the one hand, this allows a transfer at the outlet side and / or a simpler insertion of the straightening material at the inlet side.
  • the means for adjusting the lower edge straightening rollers on the outlet side and the inlet side are identical, so that only one type must be provided, which is suitable for both the outlet side and for the inlet side.
  • the construction described above also achieves the advantage that the device for moving the straightening roller can be mounted on the outside of the machine frame, which makes it easier to retrofit the machine.
  • the inventive solution is achieved in an advantageous manner that the quick change of individual straightening rollers is also possible as before, since no cassette is required because the actuating mechanism is externally mounted and there is no positive mechanical coupling to the Stauerrollenböcken. As a result, the expansion of the support roller blocks is possible as before.
  • Fig. 1 shows a partial side view of an inventive device 1 for straightening metallic material, also referred to as straightening machine.
  • the device 1 has a straightening unit 3, the upper straightening rollers 5 and lower straightening rollers 7, which are arranged offset to one another.
  • the metallic good to be straightened 9 is shown schematically.
  • FIG. 2 A perspective view of a support roller block 13 shows more clearly, the support roller block 13, a lower plate 15, side walls 17, in which the support rollers 11 are mounted.
  • the side walls 17 are made split and have an upper fastening strip 19, which serve to define the pivot bearing 21 of the support rollers 11.
  • a peripheral support roller 23 is rotatably mounted in a carriage 25.
  • the carriage 25 is mounted horizontally movable on the plate 15.
  • a guide screw 27 on each side of the support roller block 13 extends from the front end side of the side wall 17 and through the side walls 29 of the carriage 25, wherein springs are arranged around the screws pushing the carriage 25 away from the side walls 17 of the support roller block 13.
  • Fig. 1 schematically, the movement path of the peripheral support roller 23 is shown. Together with the adjacent support roller 11, it supports the marginal straightening roller 31, which is mounted rotatably about the adjacent support roller 11 by means of a rocker.
  • the movement path of the lower edge straightening roller 31 is shown schematically, whereby a "straightening" of the metallic Guts 9, as in Fig. 1 is possible.
  • the movement of the marginal lower straightening roller 31 is effected by horizontal displacement of the edge-side support roller 23, whose front and rear end position in Fig. 1 is also shown schematically.
  • Fig. 3 the device 1 according to the invention for straightening metallic material or straightening machine is shown in a perspective view. It has a lower machine stand 2 in which the lower support roller blocks 13 and the lower Straightening rollers 7, 31 are mounted.
  • a beam or yoke 35 is provided for synchronous movement of the carriage 25 and thus the edge-side support rollers 23, a beam or yoke 35 is provided. How farther Fig. 1 and 3 can be seen, actuators 37 are mounted externally on the machine stand 2, and are connected via a cylinder 39, as shown Fig. 1 seen, connected to the beam 35.
  • the lower straightening rollers 7 are each mounted at their ends in a lower bearing strip 41.
  • the rocker 33 is clearly visible, whereas Fig. 4 an outer cover 43 of the rocker 33 shows.
  • the upper straightening rollers are rotatably mounted at each of their ends in an upper bearing bar 42.
  • the edge-side lower straightening roller 31 is shown in its lowered position, ie the rocker is pivoted outwardly, which is accomplished by the actuators 37 move the beam 35 to the outside of the device 1, after which the spring-loaded carriage 25, the edge support rollers 23 also in Move towards the outside.
  • the supported by the peripheral support rollers 23 edge straightening roller then follows due to their weight of the movement of the edge-side support rollers 23 and pivots downwards.
  • an initiator 45 is disposed on the lower, front and rear bearing bar 41 each.
  • the two initiators ask the lowered position of the rocker 33 on the outer cover 43 and thus the lowered position of the edge-side lower straightening roller 31 from.
  • the advantage of using two initiators 45 is that it can be determined that the straightening roller 31 is also lowered over its entire length (at both bearing points).
  • the upper and lower straightening rollers 5 and 7 are driven by cardan shafts, not shown.
  • the device according to the invention thus a possibility is created at the outlet end to produce a targeted overriding of the metallic material or to produce at the inlet of the device easier insertion of the metallic material.
  • the mechanism for adjusting and moving the edge straightening roller (s) can be retrofitted to existing devices. The compactness of previous straightening machines without individually adjustable straightening roll (s) is essentially maintained.
