Definitions
- Object of the present invention is therefore to develop a method for generating substantially rotationally symmetrical plant tücke, in particular with tooth profiles, which allows easier, and thus faster and more cost-effective processing.
- the inventive method for producing substantially rotationally symmetrical workpieces by forming a starting material uses a forming die and a rotatable tool, wherein the die has a bore along their central axis.
- the starting material is introduced through, the bore of the die and pressed between the die and the rotating tool, so that the .Ausgangsmaterial the contour of the die accordingly flows from the central axis to the outside.
- the workpiece is thus manufactured in a single operation.
- mechanical reworking or calibrations are possible.
- As a result of the flow of material in the die and the rotation of the tool in comparison to conventional methods, only slight forming forces occur, so that the demands on the tools and thus the cost expenditure are reduced. Since the forming takes place without cutting, the resulting chamfering of the finished workpiece is also advantageous and gives the workpiece better mechanical properties.
- the method is further advantageously characterized in that the starting material can be introduced continuously and in a controlled manner into the space between the die and the tool.
- the amount of material to be formed per time unit can be optimally matched to the selected one
- the required conversion forces are limited.
- the die is fixedly mounted.
- the deformation is thus determined solely by the feed rate of the material and the speed of rotation of the tool, so that simple, cost effective control of the process can be used.
- the matrix Ikann but preferably also rotatably mounted about a rotation axis, which opens up new Möglichke_ _iten for controlling the deformation, but without j but the control to significantly complicate.
- the die speed is independently controlled by the speed of the "" tool, but the die can also co-rotate with the rotating tool, thus controlling the friction between the material and the tool what an exceptionally smooth
- the rotational speed n of the tool and / or the distance a of the tool from the die are set during the forming. In this way, the forming can be adapted to the conditions occurring, even when the method is already running.
- the center axis of the die and the axis of rotation of the tool may be aligned.
- the amount of eccentricity can preferably be adjusted so that the rotating tool rotates in an oscillating manner about the central axis of the workpiece area surrounding the workpiece.
- the eccentricity is adapted to the material to be formed or the outer dimensions of the workpiece to be produced.
- the oscillation is achieved, for example, by a radial advancing movement of the curler.
- the reduction of the frictional surface has the advantage that due to the only partial contact, less force and thus energy is required for forming.
- the Matri_ze a, preferably profiled, boundary.
- the method is therefore erfind ⁇ _ ⁇ ng sdorfe yakungsprofilen in particular for the chip-free Hers "division of workpieces with Ver" advantageous.
- Duz ⁇ rch the uniform Materialf luss and the mold filling in I matrix during the forming is therefore an accurate in side profiling of the workpiece, eg a Stirnv- ⁇ rz hint allows.
- the starting material is heated at the time of insertion or injection.
- Characterized ⁇ ver the flow properties of the material can be further reduced thereby forming forces -crestn.
- the tool has a symmetrical or asymmetrical tooling. While the one Se. ⁇ te of finished workpiece is determined by the shape or contour of the die, the possibility is given by the use of a tool with symmetrical or asymmetrical contour to influence the shape of the other side varied.
- a workpiece produced by the method according to the invention which is characterized by a non-cutting process, is accordingly characterized by a continuous and uninterrupted fiber path which is substantially parallel to the molded-on surface contour.
- Such a fiber profile increases the material load capacity, life and freedom from errors and thus overall the quality of the workpiece.
- the finished workpiece is produced in a much shorter time, which has a positive effect on the cost-benefit ratio.
- FIG. 1 shows a schematic perspective view of a die and a tool used in the method according to the invention, wherein the material contact is indicated.
- a schematic tool structure which shows a die 1 and a tool 2 arranged above.
- the die has a bore 11 through its central axis and a Konturr in the form of a Veriereungs- profiling 12, and a boundary 13 on the side facing the tool on.
- the tool is rotated at a speed n and the distance a zwi_ see tool and die can be adjusted by a feed movement _.
- the starting material 3 is mean s of a punch (not shown) continuously with a speed Zuglassges introduced into the bore 11 (arrow S), from where it is pressed into the space between the contour 12 of the die and the tool 2.
- the material By pressing in and rotating the work die acting on the material, the material flows radially outward along the contour of the die until, due to the boundary 13, material eventually fills the mold and produces the finished workpiece.
- the distance a of the amount of material in the die is adjusted.
- the material supply is controlled so that only as much material is pressed in "as is necessary for forming under the given conditions.
