Abstract

The invention relates to a method of producing a cutout or aperture in the wall of a component formed according to the hydroforming process, for example a hollow body which is located in the forming tool (1), by means of a punch (8, 10) which is displaceable from outside to inside or from inside to outside and which is pressed into the wall of the hollow body. In order to carry out a cutting process in the tool, it is proposed that the wall of the initial workpiece or workpiece mounted in the forming tool (1) and fixed and positioned preferably with sealing plungers (3, 4) first of all be precut abruptly by means of the punch (8, 10) except for a residual wall thickness. The forming process is combined with processes of chipless forming for processing the apertures and cutouts and with finishing, which take place in the tool. Furthermore, a corresponding device is proposed.

Description

  • The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 7 for producing a cutout or breakthrough in the wall of a formed by the hydroforming process component, such as hollow body, which is still in the forming tool with subsequent fine machining of the surface. Such a device or method is known from DE 103 28 452 B1 known.
  • There are hydroforming known, which allow the cutting out of cutouts from component walls from the outside inwards, as shown in the DE 43 22 063 C2 is described. This known method is carried out with the aid of an externally acting on the outer surface of the tool punch such that the cut is first precut at maximum internal pressure to a residual wall thickness and then cut at a reduced internal pressure.
  • The creation of breakthroughs or cutouts can also be carried out from the inside out ( DE 1 552 122 A1 ), in that the wall is broken or cut out by increasing the internal pressure into a tool recess, it being possible for an outwardly displaceable support punch to be provided in the tool recess.
  • In the known methods of this type, when a cutout is cut out, the material flows after it has flowed over, ie. for changing the wall surface, the component, z. B. for inclination and fringe of the edge in the area around the cutout.
  • In the prior art, a number of possibilities are known by chipless forming in the cold state (stamping, bending, pressing, cutting, punching, drawing, etc.) to bring in breakthroughs or cutouts that have a certain shape contour and tighter wall thickness and cross-sectional tolerances and to achieve better surface qualities of the component.
  • From the DE 103 28 452 B1 Furthermore, a method and a device for producing a hole on the outer circumference of a hollow profile has become known. Here, a method and a device is shown with the or a hollow holes in a hydroforming mold at almost any point in a simple manner is made possible. For this purpose, it is particularly proposed that the punch in the guide bore of the forming tool is moved with the cooperation of the internal high pressure with a drive member. In this respect, non-cutting shaping of the component or parts of the component takes place exclusively after or at most during hydroforming. In such an approach, it may happen that breakthroughs or cutouts that have a certain shape contour can be cut and shaped only with low accuracy.
  • The invention is therefore based on the object to provide a method and an apparatus of the aforementioned type, which avoids the difficulties outlined above and in which the measures described above or the like unnecessary.
  • This object is achieved by a method according to the features of patent claim 1 and a device according to the features of patent claim 7.
  • The stated object is achieved in a method of the type mentioned in that initially the wall of the stored in the forming tool and fixed by sealing stamp and positioned starting workpiece is suddenly precut with the aid of a punch puncture to a residual wall thickness. This is the abrupt. Effect of the punch realized by a distance between the upper part of the punch and Hydrozylindem. This distance serves to avoid the acceleration section of the hydraulic cylinder.
  • It is achieved that are cut and shaped with high accuracy from the wall of a produced by the internal high pressure forming process component, for example, hollow body, still in the forming befindlichem hollow body, openings or cutouts that have a certain shape contour and that the surface of the component is finished. So far, this was only possible in a separate operation outside the hydroforming forming tool.
  • In a further method step, the punch moves to the outer surface of the tool ges back. The sealing dies push the starting piece into a new position to compensate for a change in shape of the starting workpiece, ie elongation in the hydroforming, and to accurately position the precut area, ie the predetermined breaking point relative to the punch. Then the internal pressure increases, and during the forming process The cutting process of the cutouts from the component is carried out according to known methods described above, from outside to inside and / or from inside to outside. In this case, the pre-cut part of the wall of the component, ie the predetermined breaking point previously generated by the embossing edge of the punch, easily and cleanly separated by sudden urid / or multiple movements of the punch between the lower and upper dead centers.
  • After lowering the internal pressure, a complete substructure is carried out by the above-described non-cutting shaping in order to prevent inclination, edge and ridge formation of the cut and to bring in a certain shape contour having breakthroughs or cutouts. This operation is realized by means of axial movements of the workpiece by means of the sealing ram and vertical movements of the punch, which has a corresponding engraving in its front and / or side surface.
  • In a final operation, a fine machining of the surface of the component is performed. This fine machining of the surface of the component is realized during the removal process from the tool by cold drawing of the workpiece by a drawing ring mounted in the tool by means of simultaneous axial displacement and rotation of the workpiece by the sealing punch.
  • The combined internal high pressure and non-cutting shaping method according to the invention makes it possible to perform any breakthroughs and cutouts on the workpiece and a fine machining of the surface of the component with high accuracy in a single combined forming, punching, bending, Einsenk-, Ziehräumwerkzeug. In this case, this method can be carried out by appropriate joint control of the internal high pressure, the feed, dead play and the speed of the punch, the Nachschiebung and axial position of the output piece and the axial feed, the shift and rotation of the workpiece practically in one operation.
  • An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it:

  • Fig. 1 shows a longitudinal section of an apparatus for performing the method, while Fig. 2 shows a cross section of such a device in a starting position at the beginning of the process. The device or the tool has a tool 1, in which the workpiece 2, in particular a holding tube for a headrest of vehicle seats is inserted. The workpiece 2 is acted upon by sealing stamps 3, 4 end. Via an opening 5, the fluid for performing the hydroforming can be introduced into the hollow workpiece 2. The openings or cutouts in the wall of the workpiece 2 are introduced by means of punch punches 8, 10, act on the hydraulic cylinder 6, 7. The punches are held by yokes 9, 11 with bearing areas 12, 14, which are adjustable in height adjustable. This results in different distances Δ 1 , Δ 2 to the hydraulic cylinders 6, 7. The height adjustment is achieved by means of an adjustable Jochfußes 14, 16. About likewise height-adjustable abutment 13, 15, the movement of the yoke 9, 11 and thus of the punch 8, 10 is limited downwards. Jochfuß 14, 16 and abutments 13, 15 are mounted on a piston plate 18, 20, which is height adjustable by means of a hydraulic fluid 19, 21.
  • For fine machining of the workpiece 2 in the tool, a die 17 or a drawing ring is arranged on the side of the tool on which the workpiece is introduced or removed. Furthermore, one or two part-circular grooves 22 are introduced into the punches 8, 10, which serve to edge straightening of the introduced apertures or cutouts.
  • The following is the procedure with the help of Fig. 3 . 6 . 11 . 14 and 19 described, which show the different stages of work. In a first step, the workpiece 2 positioned by the sealing rams 3 is pre-cut by the punches 8, 10 in an impact-like or jerky manner. In the case of the punch 10, which then causes a complete cutout, the yoke 11 is further extended, so that there is a smaller distance Δ 1 . A shock is stopped by hitting a vertical plate on the abutment 13, as in Fig. 3 is clarified. The 4 and 5 show enlargements. The impact introduces a pre-damage into the material.
  • Subsequently, the active fluid is pumped into the interior of the workpiece 2, after the punches 8, 10 have been withdrawn to the outer surface of the tool. Since it comes to an expansion of the material during the actual hydroforming, the workpiece 2 is previously brought by axial displacement of the sealing dies 3, 4 in a position which positions exactly the predetermined breaking point to the respective punch ( Fig. 6 ). The Fig. 7-10 illustrate the subsequent cutting process under the influence of the internal high pressure. There is the possibility that the displaceable punch from the outside to the inside ( Fig. 8, 9 ) or from inside to outside ( Fig. 7, 10th ). In hydroforming, the wall of the workpiece 2 abuts against the inside 24, 25 of the tool. Cutting edges 26, 27 are formed on the cutouts or averages.
  • With the help of Fig. 11 a subsequent process step is shown, which serves the edge aftertreatment or to introduce breakthroughs or cutouts with a certain shape contour. The punch 8, 10 with the cut sheet 28 or formed sheet metal portion 31 is further guided in the direction of travel in the tool, so that the edge portions 29, 30 of the cutouts or openings are aligned with the engraved groove 22 in the punch head. The sealing rams 3, 4 are moved axially and in this way the possibly deformed by the cutting process edges straightened by the forced movement into the grooves 22. Such a reciprocation and the effects of straightening the edge portions (29, 30, 32) are from the Fig. 14-18 seen.
  • The surface calibration is then followed by a drawing process. In this case, the formed workpiece 2 is pulled through the die 17 under preferably simultaneous rotations and, due to the drawing ring, is straightened with regard to its mantle surface 33.
  • The process sequence is finally with the help of Fig. 21-27 shown. The workpiece 2 is received by the sealing dies 3, 4 and positioned by axial movement in the tool. By means of puncture acting punch 8, 10 a pre-damage is introduced into the wall. When increasing the internal pressure then follows by sudden and / or multiple movement of the punch the actual cut or average. For the treatment of the edges, they are forced by axial movement of the workpiece in an engraved groove 22 in the punch. This is followed by the calibration process with subsequent removal of the workpiece.
  • Fig. 28 shows the velocities of the respective punch, as they result from the individual distances Δ 1 Δ 2 between the upper part of the punch and the hydraulic cylinders.
