Definitions

  • the invention relates to a bending machine for straightening elongated bodies, especially pipes, plastic composite pipes, rods, or profiles.
  • a bending machine of this type is known from German Patent Application no DE 197 50 616, which is designed to straighten rolled profiles.
  • This bending machine comprises a number of straightening rollers that form a straightening channel and act on the surface of the rolled profile or elongated body that is fed into the straightening channel.
  • an adjustment element is provided that has an adjustable runout roller to guide the straightened rolled profile, and that is adjustable by means of a sensor and an adjustment regulator.
  • the bending machine is a complex, stationary piece of equipment used in rolling mills, and is not particularly suitable for mobile applications at work sites, machine shops, or workshops.
  • a bending machine for pipes, profiles, and the like is known from German Patent no. DE 235 34 428, which has a design based on a linear, straight alignment and having bends and curves with small bending radii.
  • This bending machine comprises on the one hand feed rollers between which the pipe or similar body is fed in a specified first direction, and on the other hand bending rollers on which slides are arranged that can be moved at right angles to the first direction.
  • the bending machine constitutes a compact, portable unit, the pipes, profiles, and similar bodies that are prepared in a curved or bent state cannot be straightened without further processing.
  • the feed rollers are diametrically arranged in pairs to accommodate the diameter or outer contour of the elongated body, so that for other diameters or outer contours, the rollers must be replaced by other rollers of appropriate design. This is extremely time consuming, and is not suitable for the austere operating conditions at a work site. Moreover, sets of various rollers must be kept on hand. A further significant disadvantage is that the rollers are externally accessible, resulting in potential safety hazards.
  • elongated bodies such as pipes, rods, or profiles are often processed on rollers whose diameters typically range from 1 to 2 m, corresponding to the flexibility of the elongated body. After the elongated body is rolled out, it has a corresponding bend radius such that the body generally cannot be laid out perfectly straight. Even slight curvatures are undesirable, particularly for installation techniques such as laying water pipes, especially surface installations, but also for underground installations as well. Similar problems arise in the laying or installation of rods or profiles, such as for cable ducts, sheathing, scaffolding, and the like.
  • Another object of the invention is to provide a bending machine which allows adjustments to be easily made for different diameters or outer contours of an elongated body which is to be straightened.
  • a further object of the invention is to provide a bending machine which avoids the need for special modifications.
  • a bending machine for straightening an elongated body comprising a machine frame and a plurality of straightening rollers disposed in the frame, the rollers being mounted on supports along a straightening channel displaced along and circumferentially around an axis of the straightening channel, and the straightening rollers being radially adjustable such that the elongated body can be moved through the straightening channel, wherein the supports are guided in at least one displacement plate that can be rotated about the longitudinal axis of the straightening channel; the displacement plate comprising first adjustment elements which engage second adjustment elements on the supports, and wherein the radial distance of the radially adjustable straightening rollers relative to the longitudinal axis can be changed by rotating the displacement plate.
  • the bending machine according to the invention is characterized by a simple construction that allows adjustments to be easily made for different diameters or outer contours of the elongated body to be straightened.
  • a number of straightening rollers are mounted along a straightening channel on radially displaceable supports, which together may be adjusted by a displacement plate. It is advantageous for the supports to be diametrically opposed in pairs, the supports having at least two diametrically opposed straightening rollers.
  • four supports are offset by at least approximately 90° to one another in relation to the straightening channel or the longitudinal axis, whereby each respective pair of diametrically opposed supports has at least one pair of diametrically arranged rollers.
  • the supports are mounted in the machine frame so as to be radially displaceable, so that by means of the displacement plate the radial position of the supports, and thus of the respective straightening rollers, can be specified with respect to the longitudinal axis by rotating the displacement plate.
  • the supports may be pivotably mounted about a fixed pivot bearing, or may also be mounted by means of the free bearing formed by the displacement plate so as to be radially adjustable in the required manner.
  • the displacement plate and the respective supports have mutually corresponding guide elements.
  • the guide elements may comprise a shaft and a corresponding guide groove.
  • the shaft may be associated with the support and the guide groove with the displacement plate, or vice versa.
  • the displacement plate is rotatably mounted in the machine frame about the longitudinal axis of the straightening channel, such that the radial adjustment of the supports, and thus of the straightening rollers adjoining the straightening channel, is determined in accordance with the rotational position of the displacement plate.
  • the bending machine is a compact, preferably portable unit having a total weight of a few kilograms, and it can be easily carried by one person to the desired location of use.
  • the machine frame which advantageously has a guide plate on each end, has an opening at each end for inserting and withdrawing the elongated body, with the straightening channel and the straightening rollers being situated between the openings.
  • the straightening rollers are preferably mounted radially inside each support, thus protecting against undesired access and eliminating safety hazards for the operator.
  • the bending machine includes a cutting device for cutting the elongated body to a desired length.
  • a cutting device for cutting the elongated body to a desired length.
  • pipes especially plastic composite pipes
  • the bending machine acquires a dual function, thus allowing elongated bodies to be straightened and cut within a short time.
  • FIG. 1 is a perspective view of a bending machine according to the invention
  • FIG. 2 is a longitudinal section through the bending machine along sectional plane II of FIG. 1;
  • FIG. 3 is a partial view in the viewing direction III of FIG. 2;
  • FIG. 4 is a perspective view in the sectional plane II according to FIG. 1, and
  • FIG. 5 is a view of a straightening roller.
  • FIG. 1 shows in perspective view the bending machine, comprising a machine frame having two guide plates 2 , 3 that are connected to one another by rods 4 .
  • rods 4 Corresponding to rod 4 on the right in the drawing, an additional rod is present in the region of the lower ends 6 of the guide plates 2 , 3 .

  • An adjustment handle 12 provided for rotation of the displacement plates 8 , 9 , is affixed to radially outwardly projecting cams 14 , 15 on the displacement plates 8 , 9 .
  • the guide plate 2 has an adjustment mark 16 which is correlated with markings on the outer surface of the displacement plate 8 .
  • the markings 18 relate to different diameters of a straightening channel 20 which is coaxial to the longitudinal axis 10 and which can be preset by means of straightening rollers, to be described hereinafter.
  • a straightening channel 20 which is coaxial to the longitudinal axis 10 and which can be preset by means of straightening rollers, to be described hereinafter.
  • elongated bodies, especially pipes or plastic composite pipes of different diameters can be straightened using the bending machine.
  • the marking 18 corresponding to the respective diameter is aligned with the adjustment mark 16 by rotating the displacement plates 8 , 9 in the direction of the arrow 22 .
  • Supports 24 , 25 , and correspondingly the other two supports, have bearing blocks 28 , 29 for the aforementioned straightening rollers, with only the one straightening roller 32 of the rear support diametrically opposite the front support 25 being visible in the drawing.
  • the displacement plates 8 , 9 comprise first adjustment elements which correspond to second adjustment elements of the respective support 24 , 25 .
  • the first adjustment element 36 is constructed as a groove that is spiral-shaped with respect to the longitudinal axis 10 , within which groove the second adjustment element of support 24 in the form of a shaft, not visible here, engages.
  • the adjustment elements i.e., the spiral-shaped groove 36 and the shaft engaging in groove 36 , are designed in such a way that rotation of the displacement plates 8 , 9 corresponding to the arrow 22 displaces the support 24 radially outwardly in the direction of the arrow 23 . It is understood that rotation in the direction opposite to the arrow 22 displaces the support 24 radially inwardly.
  • the adjustment elements are designed to correspond to the other axial end of the support 24 and the displacement plate 8 mounted there.
  • the three other supports can be adjusted radially in an analogous manner by means of corresponding adjustment elements. It is essential that all supports be synchronously radially displaced outwardly or radially displaced inwardly by rotation of the two displacement plates 8 , 9 that are connected by the adjustment handle 12 , so that the straightening rollers of all the supports have matching radial distances relative to the longitudinal axis 10 , corresponding to the rotational position of the displacement plates 8 , 9 .
  • the guide plate 2 has an opening 42 having a diameter which is equal to or greater than the outer diameter of the body or pipe, rod, or the like to be straightened by the bending machine.
  • the guide plate 3 on the opposite end also has a corresponding opening that is coaxial to the longitudinal axis 10 .
  • the diameters (or for profiles or rods with different outer contours, the widths) of these openings are significantly larger than the maximum diameters or the maximum widths of the outer contours, thus reliably avoiding safety hazards for the operator when inserting a pipe or other elongated body into the opening.
  • the fact that the straightening rollers are shielded by the radially outwardly mounted supports also avoids hazards for the operator.
  • the guide plate 2 on its inner side facing toward supports 24 , 25 has four radial guide grooves 46 through 49 in which shafts of the respective support engage.
  • Each support advantageously has two radially spaced shafts, and the width of the guide grooves 46 through 49 is advantageously substantially equal to the diameter of these shafts.
  • the radial length of the guide grooves 46 through 49 is matched to the radial displacement path of the supports, taking the shaft diameters into account. Functionally reliable mounting and radial guiding of the supports in the machine frame are thus assured.
  • each support may have an elongated guide body, similar to a feather key, which engages with the associated guide groove, the radial length of which is specified in accordance with the radial displacement path of the support. It should be noted that not only the front guide plate 2 according to the drawing, but also the other guide plate 3 likewise has corresponding guide grooves.
  • the radial guide elements according to the invention can be designed in such a way that shafts are mounted on the guide plates 2 , 3 and the supports have corresponding radial guide grooves.

  • the aforementioned second adjustment elements in the form of the aforementioned axially aligned shafts 40 , 41 of the respective upper or lower support 24 or 26 shown in the drawing, engage with the first adjustment elements 36 , 38 of the displacement plates 8 , 9 , with the adjustment elements being designed as spiral grooves.
  • the displacement plates 2 , 3 also contain the radial guide grooves 46 , 47 in which the second adjustment elements or shafts 40 , 41 likewise engage.
  • the shafts 40 , 41 are components of rods 50 , 51 , whose respective axial lengths are greater than the axial lengths of the supports 24 , 26 .
  • the respective supports 24 , 26 and correspondingly, the supports situated behind or in front of the plane of projection, are axially penetrated by two of the rods 50 , 51 .
