Description

  • It will be described a bending device with rotary tool. The folding device has a base mold, a rotary tool, a die, an upper mold part and a lid part.
  • The base mold part has a cylindrical cavity in which the rotary tool is arranged rotatably about a pivot axis in a sliding bed. The rotary tool has a Abkantposition, in which a Abkantprofil is aligned in a surface region of a rotary cylinder in the direction of the die. The rotary cylinder is rotatable from the bending position to an opening position about the pivot axis.
  • The swaging tool is arranged in a linear guide of the base mold part and can be lowered in the direction of the surface area of the rotary cylinder in the bending position in a sliding manner. The upper mold part has a curved receiving surface for receiving a curved plate-shaped workpiece, the edge region protrudes in the Abkantposition over the receiving surface. The lid part has a holding surface for holding the workpiece on the receiving surface.
  • Such a bending device with a rotary tool is from the document US 6,038,608 known, wherein the rotary cylinder of the rotary tool extends from one end face to another end face and is rotatably mounted on the end faces. To the rotary tool, which has a shaping surface area to bend a metallic plate in the longitudinal direction of the rotary tool, a bending or swaging tool is aligned so that the swaging tool presses an edge region of the metal plate onto the forming surface area of the rotary tool by a linear lowering movement.
  • For this purpose, the swaging tool is adapted to the shaping surface area of the rotary tool. After the shaping embossing process by the die tool, the shaping surface area of the rotary tool is pivoted away downwards by a pivot drive, so that the deformed metal plate can be removed from the folding device.
  • With the known folding device, however, only a single edge of a plate, which usually has a plurality of edges to be processed, can be processed, so that a plurality of processing steps are required one after the other to machine the edge regions of a curved metallic plate.
  • An object of the application is to simplify the structure of the folding device and to create the possibility that in a bending step simultaneously different edge regions of a workpiece can be processed shaping.
  • This object is achieved with the subject matter of independent claim 1. Advantageous developments emerge from the dependent claims.
  • To solve the problem, a bending device is described with rotary tool. The folding device has a base molding, the rotary tool, a die, an upper mold part and a lid part. The base mold part has a cylindrical cavity in which the rotary tool is arranged rotatably about a pivot axis in a sliding bed. The rotary tool has a Abkantposition, in which a Abkantprofil is aligned in a surface region of a rotary cylinder in the direction of the die.
  • The rotary cylinder is rotatable from the bending position to an opening position about the pivot axis. The swaging tool is arranged in a linear guide of the base mold part and can be lowered in the direction of the surface area of the rotary cylinder in the bending position in a sliding manner. The upper mold part has a curved receiving surface for receiving a curved plate-shaped workpiece, the edge region protrudes in the Abkantposition over the receiving surface. The lid part has a holding surface for holding the workpiece on the receiving surface. The rotary cylinder has at least on one end face a frustoconical taper.
  • The rotary tool forms an at least one-sided frusto-conical rotary die, which can be used as a thin-sheet beveled rotary slide that can produce a negative-angle shaped section with undercut portions in an edge region of a workpiece. The workpiece may be curved in a longitudinal direction and bent in the die direction and have a different die depth. The below lying and moving over a straight axis of rotation of the rotary tool, at least one side frusto-conical Rotationsgesenkform allows filling tapered and deep-changing negative angle Gesenkformen with curved shape, such as folds on fenders in the region of an edge bow, a door connection or a hood channel.
  • Further areas of use for the at least one-sided truncated cone-like Rotationsgesenkform also result for vehicle hoods, tailgates and side walls. Due to the truncated conical taper on at least one of the end faces of the rotary tool, a free space is created at the end thereof, which provides space for at least one additional machining tool on the same workpiece at the same time. This can advantageously be an additional stage in the manufacturing process of the workpiece allows and thus a significant cost savings can be achieved. For this purpose, the folding device on the front side with a truncated conical taper on an additional independent of the rotary tool processing tool, which can be provided at the end of the truncated cone-like taper.
  • In a further embodiment, the rotary cylinder has a frustoconical taper on both end faces. Thus, an additional additional of the rotary tool independent machining tool of the bending device can be provided at both ends of the front-side frustoconical tapers, which further reduces the cost and saves additional separate steps.
  • Furthermore, it is provided that the Abkantprofil has at least one undercut, which is exposed in the opening position of the rotary cylinder. This can be achieved in that the rotary cylinder is pivoted from the Abkantposition back into the open position and thereby release the undercuts, which are explained in more detail in the following descriptions of the figures, to remove the folded workpiece.
  • Furthermore, it is provided that a die part has a negative of the Abkantprofils, with a straight reduction of the die in the linear guide of the base molding a bending, profiling and / or cutting in the edge region of the workpiece is possible.
  • In this case, this bending device is particularly suitable for the body parts of a vehicle described above, wherein the receiving surface of the upper mold part and the holding surface of the lid part are adapted to a spherical shape of the respective body part. This makes it possible to edge a body part, such as a fender, a tailgate or a hood, in different edge regions, to profile or even cut off.
  • For this purpose, the die tool is connected to a linear or pivotable die drive, which lowers the die tool with high pressure on a surface region of a rotary cylinder with a Abkantprofil.
  • The rotary tool is connected in a further embodiment to a closing and opening mechanism in the region of the rotary cylinder. With this closing and opening mechanism not only the area of the rotary cylinder is pivoted, but with the rotary cylinder, the frusto-conical tapers are also moved on the end faces of the rotary cylinder.
  • In order to pivot the rotary cylinder with the tapers, the closing and opening mechanism is fixed to a lower portion of the rotary cylinder and has a pivotal arm on which a pneumatic piston rod is articulated. The pneumatic push rod is driven by a pneumatic piston in a pneumatic cylinder, which is articulated to the base molding. Thus, the rotary tool is pneumatically pivoted with rotary cylinder and frustoconical conical tapers in the Abkantposition and in the open position.
  • For this purpose, in a further embodiment of the rotary cylinder having a central guide, which cooperates with the closing and opening mechanism. This middle guide practically replaces the end-side mounting or the end-side end plates in conventional rotary tools. The center guide creates additional space to move closer to the workpiece to be machined with additional processing tools.
  • This center guide is achieved by lateral guide plates of the closing and opening mechanism, which are fixed on the pivot arm and slidably disposed between sliding walls of the sliding bed of the rotary cylinder. This makes it possible to dispense with a lateral guide, since now the axial thrust forces which act on the bending device in the region of the rotary tool, are absorbed by the lateral guide plates, wherein the sliding walls of the sliding bed form a portion of the base molding.
  • Furthermore, it is provided that the truncated conical taper has a taper angle to the pivot axis between 1 ° to 45 °. For such low taper angles, it is provided that the sliding bed of the rotary cylinder completely surrounds the frusto-conical taper, in order to achieve a secure embedding of the rotary tool in the cylindrical cavity of the base molding.
  • For frusto-conical tapers, which have a taper angle to the pivot axis between 46 ° to 89 °, it is provided that only the upper mold part of the folding device the surrounding frustoconical rejuvenation. Because of this relatively steep taper angle sufficient for guiding the rotary tool in the bending device, the upper mold part, since the molding covers the area of the cylindrical hollow shape of the base molding, which goes beyond half of 180 ° of the sliding bed. The upper molding is thus not only required to provide a receiving surface for the workpiece, but also required to position and mount in the cylindrical cavity of the base molding the rotary cylinder with the frusto-conical tapers.
  • In addition, it is provided that a transition between the frusto-conical taper and the end face of the rotary cylinder has a transition radius r between 10 mm ≤ r ≤ 50 mm. This relatively large transition radius ensures an edge-free transition from the rotary cylinder of the rotary tool to the frustoconical tapers of the end faces of the rotary cylinder.
