Definitions

  • the present invention relates to a forming tool for forming hollowware or sheet metal using a pressurized gas or fluid, said forming tool comprising at least two contour blocks forming a cavity, at least one of the contour blocks being heatable.
  • Forming under internal pressure and at increased temperature is sufficiently known in prior art.
  • the reader is referred to the documents WO 2005/092534 A1, EP 0 930 109 B1 and DE 199 44 679 C2, which are cited by way of example only.
  • An advantage is obtained if the contour blocks have a temperature that corresponds approximately to the temperature the body to be formed, such as a hollowware or a sheet metal or a board, is intended to have during forming. For this is the only way to guarantee that the workpiece to be formed substantially keeps its temperature during forming.
  • the forming temperatures range between 200° C. and 1100° C. depending on the material to be formed.
  • the document DE 101 62 438 A1 shows a top part and a bottom part of a tool, the top part of the tool being disposed on a tool holder.
  • the tool holder is a constituent part of the pressworking die, said pressworking die being disposed in the stationary housing, the press housing. It has been found disadvantageous that the heat transfer from the tool top part and from the tool bottom part into the press frame is problematic. Insofar, there is provided that, on opening the tool mould, i.e. when the two tool parts are being driven apart, the actual tool parts are separated from the press frame by spring systems. This means that the object this cited document relies upon is to minimize the heat dissipation from the tool to the tool holder.
  • a forming tool is known from DE 101 53 139 A1 wherein there are provided contour blocks, said contour blocks each comprising an insulation for the contour blocks. This document does not teach how to move the contour blocks toward each other nor does it disclose a housing provided for this purpose.
  • the tool and here in particular the two contour blocks forming the cavity, provide a temperature that substantially corresponds to the desired forming temperature of the workpiece.
  • the contour blocks are disposed in a two-part tool housing, said two-part tool housing comprising an insulation for the contour blocks, a load distribution plate being provided, which is connected to the tool housing.
  • insulating material is meant to isolate, it is characterized by poor heat conducting properties. This means that the insulating material comprises the highest possible porosity. This also means that the burst strength of insulating material is limited. It is also known that the two contour blocks forming the cavity tend to swerve outward under pressure during high internal pressure forming using a pressurized gas or fluid. This means that an insulation surrounding the contour blocks must be capable of resisting such a pressure. Thanks to the so-called load distribution means, it is achieved that the pressure forces exerted upon the environment can be distributed over a large area, the size of this area preferably corresponding to the size of the load distribution plate. This means that the size of the insulation and also the insulating material is chosen so that the pressure forces exerted by the load distribution plate upon the insulation are not suited to compress the insulation.
  • the major part of the pressure force is absorbed by what are referred to as spacers, which are provided between the load distribution plate and the base plate of the tool housing.
  • spacers which are provided between the load distribution plate and the base plate of the tool housing.
  • the load distribution plate is a constituent part of the contour block, the load distribution plate abutting directly the insulation. It is thereby provided that the load distribution plate itself is connected to the tool housing in order to make certain that it is possible to open and close the cavity when the tool housing is moved apart.
  • the load distribution plate in its quality as an independent element, is connected to the tool housing so as to abut the insulation with almost its entire surface, the load distribution plate comprising means for retaining the contour block.
  • the contour blocks are moved apart for inserting the workpiece.
  • the contour blocks are again moved toward each other and held together and it must be made certain that the two superposed contour blocks are flush with each other.
  • the contour blocks are heated differently on the one side but also to the two-part tool housing on the other side and to the parts connecting them, here in particular to the load distribution plate, which is adapted to be fixed in the corresponding housing half, said tensions preventing alignment of the superimposed contour blocks when they are solidly clamped, there is provided that the one contour block be received by the load distribution plate so as to float.
  • the top contour block is advantageously received by the load distribution plate so as to float, the two contour blocks always center themselves with respect to each other by virtue of the one float mounted, advantageously top, contour block.
  • the contour blocks comprise centering means with respect to each other in the region of their separation plane.
  • the centering means can hereby be a nose disposed on the one contour block, said nose mating with a corresponding recess on the other contour block, i.e., that it engages therein.
  • the best orientation of the two contour blocks with respect to each other is achieved if the side flanks of nose and recess are oriented at right angles with respect to each other. It has been found though that in such a case the contour blocks corrode together, meaning that they stick together, which leads to increased wear. For this reason, a clearance could be provided between the contour blocks where such corrosion is expected.
  • the nose and, corresponding thereto the recess comprise an engagement surface inclined at an angle of 20° for example.
  • Such a meshing between the two contour blocks through the nose and the mating recess is advantageously provided on substantially the entire circumference, meaning on the entire circumference in the separation plate of the contour blocks.
  • the tool housing comprises, over substantially the entire circumference, what is referred to as a screen in the region of the separation plane of the contour blocks, said screen serving as an additional burst protection.
  • This screen serving as a burst protection is more specifically provided in the region of the dies for the workpiece since there—as already explained—the two contour blocks do not engage.
  • At least the one contour block of the two contour blocks forming the cavity are mounted in the tool housing so as to float. More specifically, means for retaining the contour block, and in particular for retaining the floating contour block, are located on the load distribution plate.
  • the load distribution plate is also orientable in the tool housing, namely by lateral set screws allowing for pre-adjusting the location of the load distribution plate.
  • the contour block comprises heating means.
  • the heating means can hereby be configured to be a panel heater or a rod heater. If a panel heater is being used, the panel heater is directly connected, such as screwed, to the contour block to achieve a good heat transfer. This means that the panel heater is located between the contour block on the one side and the load distribution plate on the other side.
  • the contour block comprises suited openings for insertion thereof. In any case, it must be made certain that the contour blocks and the heaters are prevented from overheating, which can occur more specifically by arranging thermoelements on the contour blocks in connection with a corresponding control.
  • the contour blocks are mounted in the tool housing so as to be insulated.
  • the quality of insulation substantially depends on the type of insulation. This means that an efficient insulation is soft since it has a corresponding number of pores.
  • a hard insulation is for example in the form of foamed stones, e.g., Poroton stones; the openings in the Poroton stones can be filled with insulating material.
  • the Poroton stones themselves are quite resistant to pressure e.g., when compared to steel, so that this insulation seems suited for insertion between the tool housing and the load distribution plate.
  • dies are provided between the tool housing and the load distribution plate, said dies being in particular made from a material that is not heat conductive, e.g., from ceramics, and a suitably soft insulation having high insulation efficiency can be provided about the ceramic rods or supports.
  • the insulation itself can consist of several horizontal layers, said layers being configured such that the layers located nearest to the load distribution plate are much more resistant to high temperatures than those that are located farther away.
  • the layers can have different density and thickness.
  • contour blocks not only hollow bodies can be formed, but also sheet metal or boards.
  • the board or the sheet metal are preferably retained by hold down clamps.
  • at least the one contour block comprises a female part that corresponds to the final shape of the sheet metal or the board to be formed.
  • the female part be displaceable onto the other contour block so as to reduce the volume of the cavity.
  • the female part in the other contour block can comprise a surface conforming in shape to the shape of the female part of the one contour block; however this must not be so. The reduction of the volume in the cavity is of interest since on the one side a small volume reduces the risk of persons standing nearby in case of a sudden pressure drop and since on the other side it is more cost-effective.
  • the deformation of the board can only occur through gas pressure, but, in parallel thereto, the one female part can also be displaced onto the other female part.
  • a die can be provided in accordance with one variant; according to another variant, the displacement of the female part can also occur through gas pressure.

  • the coarse orientation during mounting occurs by orienting the load distribution plate 8 , 9 using screws 8 a , 9 a disposed laterally in the housing 1 .
