Description

[0001] The invention relates to a ceramic and / or metal powder press arrangement for pressing a molded part.

[0002] DE 10 2005 038 915 A1 describes a method for pressing a molded part, in which a ceramic and / or metallic powdered material to be pressed is filled into a die opening of a die, and in which the material is compacted and pressed with at least one press ram along a compression axis. A powdered material generally also includes granules or a mixture of powder and granules. A transverse ram is moved into the material along a transverse axis, perpendicular to the compression axis. The movement of the transverse ram is carried out during and / or after pressing, or after the start of the compaction process of the material along the compression axis. A device for pressing a molded part from such a material is also described.The device is equipped with a die with a die opening for receiving the material, with at least one press punch which is adjustable for pressing the material along a compression axis, with a transverse punch which is adjustable perpendicular to the compression axis for forming and / or pressing the molded part, and with a transverse punch drive device which has an eccentric drive for driving the transverse punch.

[0003] DE 10 2006 020 213 A1 describes a press for producing compacts from powder material with a die that can be clamped on a die table arranged in a press frame, in which a mold cavity with an undercut is formed, at least one upper and one lower punch that interact with the mold cavity, and adjusting drives for the upper and lower punches and the slide or the movable die part mounted in the press frame, characterized in that a sensor measures actual states of the adjusting drive for the slide, transverse pressing punch or the movable die part, the actual states are compared with a setpoint in a control device and the control device actuates the adjusting drive for the slide, the transverse pressing punch or the movable die part via the energy supply to the adjusting drive according to the difference between actual and setpoint states.

[0004] EP 2 098 317 A1 describes a method for producing a compact from metal powder using a powder press comprising a driven upper ram assembly, a driven lower ram assembly, and a die assembly forming the mold cavity. A lower part of the die assembly is filled with metal powder using a first filling shoe, after which an upper part of the die assembly is lowered onto the lower part of the die assembly by means of transverse rams inserted into the mold cavity. This lowered upper part of the die assembly is then filled with powder using a second filling shoe, after which the pressing operation is carried out and the compact is formed.The transverse punches are then retracted from the mold cavity filled by the compact and from the compact itself. The upper and lower parts of the die assembly are then removed from the compact, which is held in place by the punch assemblies. This process allows compacts with complex shapes to be produced in a single pressing operation.

[0005] A disadvantage is the complex design, which requires adapting several components of such an arrangement for each new molded part. In particular, presses with electric or predominantly electric main press drives must provide more installation space than would actually be necessary for the press components.

[0006] The object of the invention is to propose a ceramic and / or metal powder press arrangement for pressing a molded part, also using a transverse punch, which allows for simpler adaptation to other molded parts. In particular, it should enable installation in conventional press frames or adapters, whereby the installation space required laterally to the die and in the pressing direction for a transverse punch drive should be reduced.

[0007] This problem is solved by a press arrangement for pressing a molded part with the features of claim 1. Advantageous embodiments are the subject of dependent claims.

[0008] A modular ceramic and / or metal powder press arrangement for pressing a molded part from a powder and / or granular material along a main pressing direction is therefore preferred, comprising at least one die, at least one transverse adjustment drive module designed for adjusting a transverse punch in a transverse adjustment direction, and at least one holding device with an inner die receptacle for the die and with at least one outer transverse adjustment drive module receptacle for attaching at least one such transverse adjustment drive module or with at least one transverse adjustment drive module attached in this manner.

[0009] This enables, in particular, a modular design in which the press assembly can be configured as needed from suitable modules consisting of holding devices, suitable dies or die components, and suitable transverse adjustment drive modules. This also allows for quick and flexible retooling and adaptation to modified parts being pressed.

[0010] Such a press assembly can be used in a ceramic and / or metal powder press. It can also be used in an adapter, which can then be used in a ceramic and / or metal powder press. The press assembly is designed for pressing the material to be pressed, which is a ceramic and / or metallic material supplied in powder and / or granular form.

[0011] The main pressing direction is usually, but not necessarily, vertical, which is why directional terms such as top, bottom, or side may need to be interpreted differently. The lateral adjustment direction runs in a plane that, in most applications, is perpendicular to the main pressing direction. However, further developments are also possible in which the lateral adjustment direction, or this plane, runs at an angle other than 90° to the main pressing direction, for example, to create openings or embossings leading obliquely into the pressed part from an outer surface. Such an angle can be in the range of plus / minus 10°, especially ±20°, especially ±45°, but also greater.

[0012] The term "inside" refers in particular to a component located in the area of ​​a die opening, facing the die or such an area. The term "outside" refers in particular to a component located at a distance from or pointing away from the die opening.

[0013] Accordingly, the die holder on the holding device as a central module component is arranged or designed in such a way that the die with its die opening can be mounted on the holding device in an area around a main pressing axis or is mounted in the assembled state.

[0014] The external transverse adjustment drive module receptacle is designed or arranged in a region of the holding device that is further away from a main pressing axis relative to the die. In particular, this means that the transverse adjustment drive module receptacle is designed on or near an outer circumferential edge section of the holding device.

[0015] This also makes it possible, in particular, to use it in electric presses where the main pressing force is generated electrically and which can be built with a low height and width.

[0016] One embodiment consists of a press arrangement in which the transverse adjustment drive module receptacle has an edge section with a first engagement design and such a transverse adjustment drive module has a second engagement design adapted to the edge section, wherein the first engagement design and the second engagement design are designed to interlock in a main pressing direction or substantially in a main pressing direction, in particular at an angle of less than 46° to the main pressing direction.

[0017] Such intervention designs can be, for example, openings or threaded openings on one component, such as the holding device, and plug-in elements or projections or screws that can be inserted into them on the other component, such as the lateral adjustment drive module.

[0018] With a vertical main pressing direction, this type of transverse adjustment drive module mount causes the transverse adjustment drive module to automatically engage and adjust itself into the first engagement position with the aid of gravity. The larger the angle, the greater the self-adjustment. The smaller the angle—especially when parallel to the main pressing axis—the more the module is secured against lateral forces that act perpendicular to the main pressing direction when the transverse ram is actuated. The external placement of the transverse adjustment drive module mount also allows for fixation over a larger circumference of the holding device, simplifying assembly and distributing the force over a wider area.

[0019] A further embodiment consists in the fact that the holding device has at least one circumferential support section at an angle greater than 30°, in particular greater than 60°, in particular greater than 75°, in particular of 90° or about 90° relative to the main pressing direction, and that such a transverse adjustment drive module, which is inserted in the transverse adjustment drive module receptacle, is supported on the support element in the transverse adjustment direction or at an angle of less than 20°, in particular of less than 40°, in particular of less than 60° relative to the transverse adjustment direction.

[0020] Such a circumferentially supported section is preferably designed as a flat surface for the external attachment and support of the transverse adjustment drive module to the holding device, with a corresponding surface or extent preferably extending parallel to the main pressing direction or main pressing axis, which leads through the die opening. However, several support sections can also be formed, creating a discontinuous contact surface for a wall or corresponding configurations of the transverse adjustment drive module. "Relative to the main pressing direction" means that the inclination can be directed upwards or downwards, e.g., both +20° and -20° to the transverse adjustment direction relative to 0° thereto, or e.g., both 75° and 105° to the main pressing direction relative to 90° thereto.

[0021] One embodiment of this is that the first engagement design and the second engagement design, in the assembled state, engage in a mounting plane parallel or substantially parallel to a transverse adjustment plane of the transverse punch, offset in the transverse adjustment direction, and that such a transverse adjustment drive module is supported on the at least one support element in at least one area between the mounting plane and in an area beyond the transverse punch adjustment plane.

[0022] For example, the transverse punch is adjusted parallel to and above a surface of the holding device, while the contact surface extends downwards over a circumferential section of the holding device on the outside. A particularly preferred embodiment thus consists of a design with such a contact surface and engagement features running parallel to the main pressing direction, wherein the transverse punch is adjustable in a plane that does not pass through any part of the support section or the contact surface. In such an arrangement, a transverse force acting via the transverse punch is redirected, for example, by a pin of the second engagement feature engaging the holding device from above, in an outer lateral direction and by a body section of the transverse adjustment drive module, into a counterforce acting against the contact surface of the holding device.

[0023] It is also a design feature that the first intervention design or the first intervention design and the second intervention design have an elongated course.

[0024] Instead of discrete openings and corresponding elements, two-dimensional configurations, particularly elongated ones extending over, for example, a surface of the components, can also be provided, such as an elongated slot and an elongated projection in the sense of a tongue-and-groove system. If, according to a particularly preferred embodiment, the structure—for example, a longitudinal slot or a rail-shaped projection on an upper edge section of the holding device—extends further than the at least one corresponding element of the transverse adjustment drive module, the transverse adjustment drive module can be moved laterally along the engagement feature and thus easily and precisely adjusted. In particular, not only discrete positions can be set.

[0025] In the case of a particularly linear engagement design, such a design also allows for simple pivoting about an axis formed by the engagement design, so that the transverse punch can be adjusted at an angle in a plane that is not perpendicular but oblique to the main pressing direction by means of the inclined transverse adjustment drive module.

[0026] Another variation of this is that the elongated course is arc-shaped.

[0027] In particular, the first intervention design and the second intervention design exhibit a rounded shape on surfaces facing each other, perpendicular to the direction of their respective course.

[0028] The first engagement feature is, for example, a holding device with a circular circumference, which has, for instance, an annular groove or an annular rail on its upper edge. This allows the transverse adjustment drive module to be moved around the die into a suitable position and, in particular, enables fine adjustment in the transverse punch adjustment plane. In particular, not only discrete positions can be set. Furthermore, when the transverse adjustment drive module is placed onto the first engagement feature, centering and self-adjustment of the transverse adjustment drive module is achieved, especially in the radial direction and in the direction of, or parallel to, the main pressing force.

[0029] Another embodiment consists in the fact that the holding device has a fixing device on the side facing away from, in particular opposite to, the first engagement design, for receiving a force directed away from the die, in particular radially.

[0030] For example, the first engagement feature is located on the upper side of the holding device, and the corresponding fixing feature is located on the opposite edge section on the underside of the holding device. In principle, configurations in the lateral circumferential area of ​​the holding device are also possible. Such a fixing feature can be designed, in particular, as a detent element or screw connection to secure the transverse adjustment drive module to a second side of the holding device. Advantageously, this allows not only counterforces to a transverse pressing force of the punch to be transferred through the lateral support section, but also transverse forces from the transverse adjustment drive module or its housing into the holding device in a simple and reliable manner. These transverse forces can occur when a transverse punch is withdrawn from the area of ​​the die opening.

[0031] Additional or alternative further measures may include screw connections from above, a circumferential side and / or from below between the holding device and a transverse adjustment drive module attached to it.

[0032] It is also an embodiment in which such a transverse adjustment drive module has a gearbox driving such a transverse stamp and a drive, in particular a motor, wherein the drive is arranged laterally to the gearbox and the drive and the gearbox are connected to each other via a gear and / or belt drive, wherein the gear and / or belt drive is pivotably mounted about a gearbox axis of the gearbox and / or about a drive axis of the drive.

[0033] In particular, this avoids a design in which a drive shaft is guided linearly into a mechanism—for example, a crankshaft for laterally adjusting the cross punch—since, instead, a parallel and spaced-apart path of a drive shaft and a transmission shaft—for example, the crankshaft—can be arranged. The drive—especially an electric motor—and a transmission driving the cross punch can thus be arranged essentially within one plane and at the same level as the body of the holding device. In the pressing direction, this results in a flatter structure, which allows for a correspondingly low overall press height.

[0034] In contrast, a preferred embodiment allows the pivotable mounting in the belt drive area to pivot to any side of the gearbox, ultimately even next to the holding device, thus requiring minimal installation space in the radial direction. This also prevents collisions between the drive and surrounding components, such as an adapter or press frame, allowing these components to be designed more compactly.

[0035] Another embodiment consists in such a transverse adjustment drive module having a mechanism adjusting such a transverse stamp - in particular a crank gear - in a first housing section and a gear driving the mechanism in a second housing section, wherein the first and the second housing section are pivotable relative to each other and the second housing section is attached or coupled to the holding device.

[0036] The mechanism for adjusting the transverse punch is, for example, a crank mechanism or eccentric, whose driven shaft leads to a further gearbox, which is, for example, a planetary gearbox arranged between a motor and the crank mechanism. In particular, the second housing section containing the gearbox is located externally next to the holding device and simultaneously serves to attach it to the holding device. The pivoting capability of the first housing section allows the transverse adjustment direction of the transverse punch to be changed, particularly from a direction axial to the die opening.

[0037] According to a further development, the first housing section is pivotable about an axis parallel to the main pressing direction and also, or simultaneously, pivotable about a gear axis of the gearbox. In such designs, the transverse punch, or rather its angle of attack against the body to be pressed, is not only adjustable radially to the center of the die, but also pivotable in a tangential direction to the die.

[0038] Another embodiment consists in at least one gearbox of the transverse adjustment drive module being arranged radially outside the holding device in the transverse adjustment direction. It is thus emphasized for clarity that, according to a particularly preferred embodiment, at least some of the mechanically or electrically actuated components of the transverse adjustment drive module are not arranged in or parallel to the pressing direction above or below the holding device, but preferably next to it. This enables a compact design of the holding device, allowing it to be used even in presses or adapters with small dimensions perpendicular to the main pressing direction.

[0039] Another embodiment involves such a transverse adjustment drive module having a crank drive, in particular an eccentric drive. This allows for a compact design while simultaneously offering a wide range of modification options through the insertion of different eccentric discs to set different adjustment ranges of the transverse ram.

[0040] However, other drive types and gear types can also be used, such as direct linear drives or adjustable cross punches via adjustable wedge surfaces.

[0041] A preferred lateral adjustment drive module has an electric motor drive as its drive, whereby, optionally, for example, an electric motor transverse linear drive, a mechanical or a hydraulic drive can also be used.

[0042] One embodiment of this is that a transverse adjustment plane of the transverse punch is arranged offset in its transverse adjustment direction, in particular parallel to an adjustment plane of the crank mechanism. This decouples elastic deformations in the main pressing direction from the transverse pressing direction.

[0043] A ceramic and / or metal powder press or an adapter of such a press with such a press arrangement inserted therein is also preferred independently.

[0044] A preferred embodiment is one in which the press is equipped with a hydraulic, mechanical or electromechanical main pressing force drive.

[0045] Another embodiment of such a press is one with two such holding devices, each with an inner die receptacle and each with at least one outer transverse adjustment drive module receptacle with at least one transverse adjustment drive module, wherein the second holding device together with the components arranged thereon is arranged above the first holding device and the die is formed in the die receptacles in at least two parts along the main press axis.

[0046] In particular, the second holding device and its components are arranged upside down compared to the first holding device and its components. In other words, a configuration is also possible in which a press assembly is used in both the upper and lower, relative-to-each-other adjustable components of the press or adapter. This assembly has die components at both the top and bottom that are moved against each other to press the molded body or part. This allows, for example, the production of so-called chip breakers, which have projections extending laterally from a central body in different planes.

[0047] The design of one-piece punches that can be coupled to the eccentric drive is advantageous, as such punches can be provided for a variety of punch structures and the like. Furthermore, the punches, which constitute a wear part in such an arrangement, are easily replaceable. Preferably, such an arrangement allows for rear support of the eccentric drive on the holding device via a housing of the transverse adjustment drive module.

[0048] An exemplary embodiment is explained in more detail below with reference to the drawing. It shows: Fig. 1. A lateral partial sectional view of components of a press assembly to illustrate the construction of a transverse punch drive and Fig. 2 A partially cutaway top view of such an arrangement.

[0049] As from Fig. 1 and Fig. As can be seen in Figure 2, an exemplary ceramic and / or metal powder press arrangement 10 for pressing a molded part from a ceramic and / or metallic material 11 consists of several components which can be combined as modular components.

[0050] For pressing, the material 11 is filled into a die opening 12. Within the die opening 12, the material 11 is pressed into the desired structured part or body by means of one or more press rams 13. The press rams 13 are adjustable along a main pressing axis in a main pressing direction x with respect to a main pressing force.

[0051] The die opening 12 is formed in a one- or multi-part die 14. The die 14, particularly as a modular component, is attached or arranged on or in a holding device 15. Specifically, a die receptacle 16 is arranged or formed internally in and / or on a surface of the holding device 15 to receive the die 14. The die receptacle 16 can optionally also be composed of several individual components spaced apart from one another, surrounding a central through-opening designed for the passage of the press punches or for the passage of press punch-supporting components 47.

[0052] On the outside of the holding device 15, a transverse adjustment drive module receptacle 17 is formed, which is designed for attaching and in particular temporarily fixing one or more transverse adjustment drive modules 18.

[0053] A transverse punch 19 is coupled to, formed with, or attached to the transverse adjustment drive module 18. The transverse adjustment drive module 18 allows the transverse punch 19 to be adjusted so that a front section of the transverse punch 19 can be inserted laterally or transversely to the main pressing direction x into the die opening 12 in its longitudinal direction y, i.e., a transverse adjustment direction y. For this purpose, the front section of the transverse punch 19 is guided from the outside through a suitable opening in the wall of the die 14 and into the die opening 12. Depending on the design, the transverse punch 19 serves to create an external embossing after final compaction of the pressed part, to compact the material 11 from the side during the main pressing process, or to be inserted into the die opening 12 before the start of a main pressing process or before the material 11 is filled into the die opening 12.In addition to transverse or oblique depressions, through openings can also be formed.

[0054] The die 14 consists, by way of example, of at least one annular outer die component 20, which has a through-opening along the transverse adjustment direction y. This through-opening also serves as a guide for a central section of the transverse punch 19. At least one inner die component 21 is inserted into the outer die component 20 and forms the actual die with the die opening 12. A through-opening for the front section of the transverse punch 19 leads through the inner die component 21.

[0055] This inherently modular design allows, for example, an outer die component 20 to be provided with a large number of possible openings, potentially extending circumferentially, and which can optionally be designed to rotate around the main pressing axis. The inner die component 21, on the other hand, is specifically adapted to the design of the part to be pressed. However, one-piece dies can also be used.

[0056] A slide track 22 is also inserted on the upper side in a section of the outer matrix component 20, over which a slide 23 is guided, which serves to fill the matrix opening 12 with the material 11.

[0057] The holding device 15 is supported on or attached to a press or adapter frame 24 from below. In the case of a die arrangement adjustable within the frame, the holding device 15 is instead adjustableally mounted on corresponding guide rods along the main pressing direction x.

[0058] In the example in Fig. In the embodiment shown in Figure 1, two lateral adjustment drive modules 18 are attached to the holding device 15 in an opposing orientation. However, fewer or more such lateral adjustment drive modules 18 can also be arranged on the holding device 15, as shown by way of example in Figure 1. Fig. Figure 2 shows that the number of lateral adjustment drive modules 18 is ultimately limited by the circumference of the holding device 15 and the lateral extent of the individual lateral adjustment drive modules 18.

[0059] In the exemplary holding device 15, the transverse adjustment drive module receptacle 17 is designed as a circumferential, ring-shaped, projecting protrusion as a first engagement feature 26. This protrusion can be angular, in the manner of a rail, or, as shown, with an arcuate upper surface. The protrusion is formed, in particular, directly on an upper surface extending transversely to the main pressing direction x at the lateral circumferential edge of the holding device 15.

[0060] The lateral adjustment drive module 18 has a mounting section 25 which, in this embodiment, features a downward-facing hook-shaped projection as a second engagement feature 27. Viewed from below, the second engagement feature 27 forms a groove into which the projection of the first engagement feature 26 engages when the lateral adjustment drive module 18 is placed. The hook-shaped projection extends radially from a housing wall of a housing 29 of the lateral adjustment drive module 18.

[0061] Below the hook-shaped projection of the housing 29, the housing 29, with its wall 39, rests in contact with a circumferential wall of the holding device 15, the circumferential wall forming a support section 28 of the holding device 15. An advantageous distribution of a transverse force Fq is shown with reference to the transverse adjustment drive module 18, which is only partially sketched on the left side of the illustration. A transverse force Fq acting in the outside direction via the transverse pin 19 is deflected from above the holding device 15 in the outside direction and via the components of the transverse adjustment drive module 18, and introduced into the holding device 15 on the outside at the support section 28. The hook-shaped engagement feature 27 acts as an intermediate deflection point.

[0062] Preferably, the housing 29 of the transverse adjustment drive module 18 is formed from a first housing section 35 and a second housing section 36 arranged parallel to the main pressing direction x. The first housing section 35 supports a gear or a mechanism 37 for converting a rotational movement into a translational linear movement for adjusting the transverse punch 19 and is designed, for example, as a crank drive, in particular as an eccentric drive.

[0063] An example is shown of the arrangement with a transverse adjustment plane of the transverse punch in the transverse adjustment direction, which is arranged offset in or parallel to the main pressing direction to a gear adjustment direction y1 of the crank gear 37.

[0064] The offset arrangement is particularly easy to implement using a punch holder 42, which is coupled to the rear of the crank mechanism 37 and which has a C-shaped mounting rail 43, the mounting rail 43 extending parallel to the main pressing direction x. The exemplary transverse punch 19 accordingly has a rear projection 44. The rear projection 44 of the transverse punch 19 causes it to be fixed in the mounting rail 43 in the transverse adjustment direction y, but adjustable in the direction of the main pressing direction x.

[0065] A drive shaft 41 leads from the mechanism 37, which is in particular a crank mechanism, to a gearbox 30. The drive shaft 41 runs along a gearbox axis 31, which in particular runs parallel to the main press axis. The gearbox 30 is designed to convert a rotary motion provided directly by a drive 33 or preferably via a belt drive 32 into a rotational speed suitable for the crank mechanism 37.

[0066] The drive 33, with its drive shaft 40, is preferably arranged parallel to the transmission axis 31 along a drive axis 34 and is spaced from the housing 29 in, for example, a radially outward direction. By means of a preferably pivotable mounting of the belt drive 32 in the mounting area on the housing 29 about the transmission axis 31, the drive 33 is pivotably arranged about the housing 29. This allows the drive 33 to be arranged in a position laterally to the radial direction next to the housing 29, so that less installation space is required for the transverse adjustment drive module 18 in the radial direction from the perspective of the die opening 12. Fig. Figure 2 shows exemplary positions of the drives 33 .

[0067] The gearbox 30 is preferably arranged in the lower second housing section 36. According to the preferred embodiment, the upper first housing section 35 is pivotable – in particular pivotable about the gearbox axis 31 – relative to the second housing section 36. This allows, in particular, the pivoting of the first housing section 35 and thus also of the transverse punch 19 to be adjusted. This allows the transverse punch 19 to be adjusted not only radially towards the center of the die opening 12 but also at an angle to it.

[0068] A pivoting of the transverse punch 19 out of the plane perpendicular to the main pressing direction x is, if desired, achievable by corresponding pivoting of the housing 29 about, for example, the mounting section 25 and the transverse adjustment drive module receptacle 17 or of its housing sections 35 , 36 relative to each other.

[0069] Optionally, fastening elements 45, in particular screw bolts for connecting components, such as the gearbox 30 to the housing 29 or to its second housing section 36 and for fastening the housing 29 to the holding device 15, may be provided.

[0070] On one side opposite the first engagement feature 26, the retaining device 15 has a further fastening element 46 in the form of, for example, a recess. A projection of a fixing device 38 is inserted in the recess, the fixing device 38 extending hook-shaped from the projection in the outer direction and then parallel to the main pressing direction x to the housing 29. The fixing device 38 serves—if required at all—advantageously, among other things, to support the absorption of the transverse force Fq directed away from the die 14.

[0071] The holding device 15 can also be provided as a modular component in various configurations for use in different types of presses, adapters, or for differently dimensioned dies 14 or transverse adjustment drive modules 18. In particular, the holding device 15 can be designed not only as an essentially plate-shaped body, but also, for example, as a frame-like component.

[0072] Instead of a prominent projection, the transverse adjustment drive module receptacle 17 can, for example, also be formed by a circumferential annular groove into which corresponding hook-shaped or semicircular projections of the mounting section 25 of the transverse adjustment drive module 18 lead. Instead of a circumferential annular structure, several individual structures in the form of projections and / or recesses can also be provided as engagement features in the circumferential area of ​​the holding device 15.

[0073] Instead of arranging the engagement feature 26 directly at the edge of the holding device 15, a suitable engagement feature can also be designed as a section shifted from the circumferential edge towards the die on the holding device.

[0074] These and other modifications, as well as combinations of the various designs and modifications, are also possible. Reference symbol list 10 Ceramic and / or metal powder press arrangement 11.
