Definitions

  • the invention relates to a press tool position adjustment device for pressing in particular ceramic or metallurgical compacts.
  • a tool In vertical presses, a tool is clamped between two press dies which can be moved vertically relative to one another or away from one another.
  • the tool has at least two mold parts, between which there is a mold part gap, which is filled before the pressing process with a ceramic powder or granules.
  • the filling takes place either by at least one filling channel from the outside in composite moldings or before placing an upper mold part on a lower mold part by filling the lower mold part.
  • the powder or granules is compacted to form a ceramic compact or ceramic article. This is removed after lifting the upper molding from the lower mold part of the molding space and fed to a post.
  • the post-processing consists in particular of a deburring, a grinding and a Verschwammen, before the compact is fired in an oven.
  • the moldings can be fastened in the simplest embodiment directly to the press dies, but this disadvantageously long downtime when replacing molded parts result. Therefore, the moldings are usually provided as part of a tool, so that parts of the assembly work outside the actual Press can be done and only a limited number of tool parts with attached moldings in the press must be permanently installed.
  • the compact is after the pressing process in a vertical orientation.
  • the demolding of the compact or article is carried out by separating the two mold parts in the horizontal direction of movement, whereupon the compact falls out of the mold part space or out of the tool on a conveyor belt. Via this conveyor belt, it then slides over an arcuate path on a horizontal surface, from which it can then be lifted and transported away for post-processing.
  • the disadvantage here is that in each case deformations of the compact can be caused by the falling out of the compact from the tool on the conveyor belt, the sliding down on the conveyor belt and the sliding down of the conveyor belt on the base.
  • Non-circular compacts are not as stable as compacts having a circular geometry, as in conventional plates, for example. Especially with multi-dimensional differently shaped compacts with different high top edges and different radii of curvature along the circumference there is a risk of greater deformation.
  • the long filling times are disadvantageous in comparison to the filling times with a vertical filling of the molding space in a horizontal press, so that only a small power or a lower pressing cycle can be achieved compared to horizontal presses.
  • a sufficient density of pressed material can be achieved in the lower region, filling defects such as denaturation can be expected at the upper edge, just as with very large compacts in their middle region is. This leads to shadows and streaks and a correspondingly high reject rate.
  • the sliding table is then displaced laterally, so that the second tool part, which was filled with the pressed material, is pushed into the press and clamped there.
  • the other lower tool part can be emptied, cleaned and filled with new pressed material.
  • roller systems For the production of, for example, deep cans or vases and conventional casting or roller systems are known, however, also allow only a small unit performance and also are not fully automated.
  • a ceramic raw material is applied to a rotating disk and shaped from the basic principle similar to the pottery with a potter's wheel to a ceramic article.
  • Such presses often have an interchangeable tool frame or molding, as for example DE 196 24 298 A1 is known.
  • Out JP 09038796 A there is known an exchange device for various such tools or molds, wherein a plurality of tools in a rotating about an axis arrangement relative to a press device located outside this arrangement is pivotable. With a hydraulic thrust system can be pushed in each case a form in the press or withdrawn from this. This allows a quick mold change for the production of various compacts.
  • the filling of the molds with a powder to be compacted takes place in the press. In this case, the mold is during filling in each case in the subsequent pressing position, ie with their usually horizontal upper edge in a plane perpendicular to the pressing direction.
  • US 1,639,081 A discloses a press tool position adjustment device, according to the preamble of claim 1.
  • US 2,095,299 A describes an injection molding plant for producing plastic compacts. Described are two molded parts, which can be moved out laterally from a press axis and opened in a scissor-like manner in order to fill them or remove shaped compacts. However, it is a structure that lets the plastic compacts fall out of the mold parts only uncontrolled, so that use in conjunction with still to be sintered compacts is excluded.
  • Out EP 0 893 218 A is generally a press assembly for pressing clay blanks to compacts known, but not for pressing ceramic or metallurgical compacts of a powdered or granular material.
  • one of two mold parts is pivotally mounted in order to be able to pivot this molded part in the separate state from the other mold part for placing a blank or for removing a molded press part from a press axis.
  • the two mold parts always remain firmly connected to the actual press arrangement.
  • the object of the invention is to provide an improved press tool position adjustment device for a press arrangement, which on the one hand enables a short cycle time on the other hand free design possibilities of the compacts or ceramic articles.
  • a press arrangement for pressing ceramic compacts has an actual press and one or more tool-providing or tool-processing devices outside the actual press.
  • a tool displacement device By means of a tool displacement device, the tool can be moved back and forth between these two basic positions.
  • the actual tool with the mold parts is designed as an adapter.
  • such a press arrangement allows the filling of the tool or the free space between the mold parts in the tool outside the actual press and also in a relative to the pressing position in the plane of the pressing force force pivoted position of the tool or the moldings.
  • the two aspects required for this, on the one hand the positional adjustment by the attitude adjustment device and the other filling the actual press by means of the tool-filling device, respectively according to the features of claims 7 and 8 are inventively inventive and are fiction united by the ideal combination of both options ,
  • a variety of such tooling and corresponding tool displacement means outside the actual press and the use of an adapter with inserted upper and lower parts offers a wide variety of possible variations.
  • By means of appropriate manual measures or movements carried out automatically by means of a control device it is possible, for example, to use different tools for completely different compact forms on a press. This is made possible by the arrangement of all molded parts within an adapter. In particular, the filling of the various adapters or tools with different Pressed goods at the various tool-providing facilities possible.
  • an adapter with the tool and moldings used in particular also makes it possible to provide a tool-filling device which, in addition to a holding device for holding the adapter or tool with assembled moldings and a conventional filling device for filling the mold part gap with a pressed product, also provides a position adjustment device having.
  • the position adjustment device it is possible to bring the adapter or the tool in preferably any positions, so that, for example, an arrangement of the moldings for a vertical pressing operation, a pivoting of the entire assembly for filling in a 90 ° offset position is possible.
  • the filling of the molding part gap in the vertical direction can take place, so that on the one hand a fast and uniform Filling, as in otherwise horizontal presses, is possible and on the other hand, a vertical pressing operation is enabled, which allows the use of a variety of tool-providing facilities.
  • the finished compact can be removed after lifting the upper mold part of the mold base without falling on a conveyor belt.
  • the position adjustment device which preferably has a pivoting mechanism for the adapter or the tool, thus offers the advantages of both horizontal and vertical presses with regard to the filling of the mold part gap and with a view to the removal of the compact. In particular, it is also possible to allow an adjustment of the position in different spatial directions between the two layers described above.
