Definitions

  • the invention relates to a method for bending flat metal material such as structural steel mat, in which a bending element such as a bending rod acts to the required extent on the material on a support after it has been fixed, and to a device, in particular for carrying out the method.
  • Rod-shaped materials can be bent to the desired extent using so-called bending slides in order to achieve the final shapes of the desired geometries.
  • the object of the present invention is to develop a method and a device of the type described above in such a way that the material can be fixed and bent in any desired position relative to the bending element using structurally simple means, neither fixing nor removing the material causing problems .
  • the object is essentially achieved in that the material is clamped between the support and a lowerable holding element.
  • the material no longer needs to interact with hooks like fingers to ensure setting. Rather, it is sufficient that the material, as soon as it lies in the desired position on the support, is held by the lowerable holding element.
  • the holding element can be pulled out laterally of these, so that the bent material itself can consequently be removed without difficulty.
  • the holding element When rotating the material with respect to the bending element such as a bending rod, the holding element only needs to be raised to the extent that the material itself can be moved or rotated.
  • a device for bending sheet material such as structural steel mat comprising a support for the material and at least one bending element such as a bending rod, which acts on the material to the extent necessary for bending, is characterized in that a holding element for clamping the material in the direction of the support is lowerable.
  • the holding element can be designed to be displaceable perpendicular to the conveying direction of the material, in order to enable removal from a closed form.
  • the invention is characterized in that the holding element is flat in relation to the side facing the support. This enables the material to be clamped in place without excessive forces having to act on it.
  • the holding element in turn serves as a stop for bending elements.
  • the holding element can e.g. be designed as a triangular column-shaped element, which can consist of a T-iron with the web with the flanges connecting steel sheets. These sides then serve as a stop surface for the bending element such as a bending rod.
  • the bending element is preferably based on a square tube which can be pivoted below, preferably in the region of the bending line of the holding element and parallel to this axis.
  • the square tube itself can be pivoted using hydraulic cylinders.
  • a structuring device is provided with structurally simple means, with the aid of which a correct fixing of the material to be bent is possible without the need for hooks or the like for fixing the material itself.
  • the holding element itself can start from brackets present in its end regions, which in turn can be connected via e.g. a chain drive or hydraulic cylinder are displaceable.
  • a bending element can be arranged pivotably on both sides of the support in order to make bends clockwise or counterclockwise.
  • two devices which can be moved relative to one another can be provided.
  • the frame of one device can be designed so that the other device partially includes, so that the distance between the bending lines can optionally be selected to be very small.
  • a device (10) for bending rod-shaped material such as steel mesh is shown.
  • the device comprises a support (12), a holding element (14) and a bending element (16) as essential components.
  • a support (12) which in the exemplary embodiment comprises a square tube (18) as the base part, roller tracks (not shown) are arranged, along which the flat material is displaced in order to be introduced into the area between the support (12) and the holding element (14) or to be removed from it.
  • the holding element (14) consists of a triangular column which is constructed from a T-bar (20) with obliquely extending flat bars (22) and (24).
  • the base edges are formed by round bars (26) and (28).
  • the base edges (26) and (28) also serve as bending lines for the material.
  • the inclined surface (22) acts as a stop for the bending element (16).
  • the holding element (14) is in turn received by a holder (30) which can be raised or lowered along column elements (32) by means of hydraulic cylinders (34) or chains (36) or (38). The latter occurs when a material to be bent comes to rest on the support (12) and is to be held against uncontrolled movement. Flat clamping is achieved by means of the device.
  • the holding element (14) can be displaced perpendicular to the plane of the drawing), that is to say it can be moved relative to the holder (30), namely when the material is bent into a closed form, in order to pull the holding element out of the form and remove the bent material to be able to.
  • the bending element (16) in the form of a bending rod starts from a square tube (40).
  • the square tube (40) can be pivoted about an axis (42) which runs parallel to the longitudinal direction of the holding element (14) and runs below the bending line specified by the round bar (26).
  • the axis of rotation (42) is based on the support (12), in the exemplary embodiment in front of the square tube (18). The pivoting of the square tube (40) and thus the bending element (16) takes place via hydraulic cylinders (44).
  • the hydraulic cylinder (44) starts from a carriage (46) which receives the device (10) and which is designed to be displaceable along a rail (48) in order to be able to move the device relative to the material to be bent.
  • the exemplary embodiment according to FIG. 2 shows a holding element or bending punch (48) which, as mentioned, can be raised or lowered via chain elements (36) and (38). 1 are not shown in FIG. 2 for reasons of clarity. However, it can be seen that the holding element (48) also has a triangular shape, the base edges specifying the bending lines. The holding element (48) can also receive the pillars guiding the chains (36) and (38) Enforce (50) and (52), namely when the holding element (48) is surrounded by a closed shape of curved material.
  • each bending device (54) or (56) comprises a support surface (58) or (60), each of which is assigned a holding element, not shown, in order to clamp the flat material like a structural steel mat (62) when the bending position has been assumed .
  • a bending element (64) and (66) or (68) and (70) is arranged on both sides of the bearing surface, the structure and pivoting corresponding to the bending element (16) and the elements described in this connection he follows. To simultaneously remove the material (62) e.g.
  • the bending lines being to be at a desired distance from one another, it is provided that the device (56) can be displaced relative to the device (54) in accordance with the arrow representation (72). In this way, various positions can be assumed, which are also indicated by the dashed line.
  • the material (62) can then be bent simultaneously around the bending line (74) and around the bending line (76) or (76 '), namely when the bending element (64) or (70) in the direction is pivoted onto the material (62), i.e. out of the drawing plane.
  • the bending devices (54) and (56) can be moved together very closely.
  • the reason for this is that the holding and traveling frame of the bending device (56) laterally surrounds the bending device (54), so that only a small distance between the bending lines (74) and (76 ') can be set in accordance with the broken line.
