EP2931511B1 - Ceramic and/or metal powder press arrangement for pressing a moulded part - Google Patents

Description

The invention relates to a ceramic and/or metal powder press arrangement for pressing a shaped part.

DE 10 2005 038 915 A1 describes a method for pressing a molded part, in which a ceramic and/or metal powdery 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 ram along a compaction axis. A material in powder form is also generally understood to mean granules or mixed powder and granules. A transverse stamp is moved into the material along a transverse axis perpendicular to the compaction axis. The transverse ram is adjusted during and/or after the pressing or after the start of the compaction process of the material along the compaction axis. In addition, a device for pressing a molded part from such a material is described. The device is equipped with a die with a die opening for receiving the material, with at least one press ram which can be adjusted along a compression axis for pressing the material, with a transverse ram which can be adjusted perpendicularly to the compression axis for shaping and/or pressing the molded part, and with a cross punch drive device which has an eccentric drive for driving the cross punch.

A disadvantage is the complex structural design, which requires the adaptation of several components of such an arrangement for each new molded part to be pressed. In particular presses with an electric or predominantly electric main press drive have to make more space available than would actually be required for the press components.

US2011027400A1 discloses a powder press for producing a metal powder compact according to the preamble of claim 1. The powder press comprises an upper punch assembly and a lower punch assembly which receives the die assembly which forms a mold cavity into which the metal powder is filled, whereupon the pressing operation is carried out. The lower punch assembly is provided with a platen on which the die assembly is placed and to which platen cross presses are attached. Each transverse pressing device is equipped with a transverse pressing ram that can be driven linearly by a drive unit and that can be pushed into and pulled out of the mold cavity through an opening in the die in the transverse pressing direction, which is essentially perpendicular to the pressing direction. The drive unit of each transverse press device comprises a linear drive unit having a fixed part fixed to a frame of the squeeze press device and a part linearly movable relative to the fixed part, the movable part being connected to a first wedge whose wedge face acts on the wedge surface of a second wedge which is transversely movable substantially perpendicular to the first wedge.

US7467937B1 discloses a high temperature, high pressure press apparatus having a cartridge assembly suitable for connection to a unitary frame. An anvil is attached to a front end of a cylindrical body of the cartridge, and a hydraulic chamber within the body is adapted to apply axial pressure to the anvil. A threaded end of the anvil is adapted for mating with a threaded diameter of a drilled hole located in a wall of the frame. A radial compression member disposed about an outer diameter of the body is adapted to limit radial expansion of the body proximate the hydraulic chamber. At least one mechanism is there radial compression member attached to preload the threaded connection between the cartridge assembly and the frame.

The object of the invention consists in proposing a ceramic and/or metal powder press arrangement for pressing a shaped part using a transverse punch, which enables simpler adaptation to other shaped parts. In particular, installation in conventional press frames or adapters should be made possible, with the installation space required for a transverse punch drive on the side of the die and in the pressing direction being reduced. This object is achieved by a press arrangement for pressing a molded part with the features of patent claim 1. Advantageous configurations are the subject of dependent claims.

Preference is therefore given to a modular ceramic and/or metal powder press arrangement for pressing a molded part from a powdery and/or granular material along a main pressing direction, having at least one die, at least one transverse adjustment drive module, which is designed to adjust a transverse punch in a transverse adjustment direction and at least one holding device with an inside die receptacle for the die and with at least one outside 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 way.

In particular, a modular structure is thus made possible, in which the press arrangement can be assembled as required from suitable modules consisting of holding devices, suitable dies or die components and suitable transverse adjustment drive modules. this makes possible in particular, a fast and flexible changeover and adaptation to modified molded parts to be pressed.

Such a press arrangement can be used in a ceramic and/or metal powder press. Such a press arrangement can also be used in an adapter, which can then be used in a ceramic and/or metal powder press. The press arrangement is designed for pressing the material to be pressed, which is a ceramic and/or metallic material that is provided in powder form and/or granular form.

The main pressing direction is usually, but not necessarily, vertical, which is why directional terms such as e.g. up, down or sideways may also have to be interpreted in a different way. The transverse adjustment direction runs in a plane which, in most applications, runs transversely or perpendicularly to the main pressing direction. However, further developments can also be realized in which the transverse adjustment direction or this plane runs at an angle other than 90° to the main pressing direction, for example to form openings or embossings leading into the pressed molded part at an angle. Such an angle can in particular be in a range of plus/minus 10°, in particular ±20°, in particular ±45°, but also more.

Inside is understood in particular to mean that a corresponding component is arranged in the area of a die opening facing the die or such an area. Outside is understood in particular to mean that a corresponding component is arranged at a distance from the die opening or in a way that points in the direction.

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

The outside transverse adjustment drive module receptacle is correspondingly designed or arranged in a region of the holding device which is further away from a main pressing axis relative to the die. In particular, this means that the transverse adjustment drive module receptacle is formed on or near an outside peripheral edge section of the holding device. In particular, this also enables use in electric presses in which the main pressing force is generated electrically and which can be constructed with a small height and width.

The holding device of the ceramic and/or metal powder press arrangement also has at least one peripheral support section at an angle greater than 30°, in particular greater than 60°, in particular greater than 75°, in particular 90° or approximately 90° relative to the main pressing direction, with 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 60°, in particular less than 40°, in particular less than 20° relative to the transverse adjustment direction.

Such a section that can be supported on the circumference is preferably designed to be flat so that the transverse adjustment drive module can be placed on the outside of the holding device and supported thereon, with a corresponding surface or extension preferably being parallel to the main pressing direction or Main pressing axis, which leads through the die opening extends. However, several support sections can also be formed, for example, which form 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 in the sense of, for example, both +20° and -20° to the transverse adjustment direction in relation to 0° thereto or, for example, both 75° and 105° to the main pressing direction Relation to 90° to it.

One embodiment consists of a press arrangement in which the transverse adjustment drive module receptacle has an edge section with a first engagement configuration and such a transverse adjustment drive module has a second engagement configuration adapted to the edge section, the first engagement configuration and the second engagement configuration being in a main pressing direction or in the Essentially a main pressing direction, in particular at an angle of less than 46 ° to the main pressing direction are formed interlocking.

Such engagement configurations can be, for example, openings or threaded openings on one component, for example the holding device, and plug-in elements or projections or screws that can be inserted into them on the other component, for example the transverse adjustment drive module.

With a vertical course of the main pressing direction, such a transverse adjustment drive module receptacle has the effect that the transverse adjustment drive module automatically latches and adjusts in the first engagement configuration with the assistance of gravity. The bigger the Angle is, the more self-adjustment is supported. The smaller the angle is - especially in the case of a course parallel to the main pressing axis - at the same time a fixation against transverse forces is carried out, which act transversely to the main pressing direction when the transverse stamp is actuated. The external arrangement of the transverse adjustment drive module receptacle also enables fixing over a larger peripheral area of the holding device, which simplifies assembly and enables force distribution over a larger surface area.

One configuration of this is that the first engagement configuration and the second engagement configuration in the assembled state engage in one another offset in a fastening plane parallel or essentially parallel to a transverse adjustment plane of the transverse stamp in the transverse adjustment direction and that such an inserted transverse adjustment drive module on the at least one support element in at least one Is supported area between the mounting level and in an area beyond the cross stamp adjustment level.

For example, the transverse stamp is thus adjusted parallel and above a surface of the holding device, while the contact surface extends downwards on the outside over a peripheral section of the holding device. A particularly preferred further development consists in a configuration with such a contact surface and engagement configurations running parallel to the main pressing direction, with the transverse stamp being adjustable in a plane which does not run through an area of the supportable section or the contact surface. In such an arrangement, a transverse force running across the transverse punch is suppressed by, for example, a pin engaging in the holding device on the top side of the second Engagement formation in the outboard lateral direction and deflected by a body portion of the transverse adjustment drive module to a counteracting force acting against the abutment surface of the retaining device.

It is also a configuration that the first engagement configuration or the first engagement configuration and the second engagement configuration has/have an elongate course.

Instead of discrete openings and counter-elements for the openings, configurations extending two-dimensionally, in particular oblong over, for example, a surface of the components can also be provided, such as an oblong slot and an oblong 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 - is designed to extend longer than the at least one counter-element of the transverse adjustment drive module, the transverse adjustment drive module can be moved in the lateral direction along the Intervention design can be moved and adjusted easily and precisely. In particular, not only discrete positions can be set.

In the case of an engagement configuration that runs in particular linearly, such a configuration also enables simple pivoting about an axis formed by the engagement configuration, so that the transverse punch can be rotated by means of the inclined transverse adjustment drive module at an angle in a plane that is not perpendicular but inclined to the main pressing direction. is adjustable.

A further refinement of this is that the longitudinally extending course is an arcuate course.

In particular, the first engagement configuration and the second engagement configuration have a rounded profile on surfaces facing one another transversely to the direction of their respective profile.

The first engagement configuration is thus, for example, a circular perimeter retainer having, for example, an annular groove or rail on the top edge thereof. This enables the transverse adjustment drive module to be displaced around the die into a suitable position and, in particular, a fine adjustment in the transverse stamp adjustment plane. In particular, not only discrete positions can be set. In addition, when the transverse adjustment drive module is attached or in particular placed on the first engagement configuration, the transverse adjustment drive module is centered and self-aligned in particular in the radial direction and direction of or parallel to the main pressing force.

A further configuration consists in that the holding device has a fixing device on a side facing away from the first engagement configuration, in particular on the opposite side, for absorbing a force directed in particular radially away from the matrix.

For example, the first engagement configuration is located on an upper side of the holding device and the fixing device is correspondingly in the opposite edge section on the underside of the holding device. In principle, configurations can also be implemented in the lateral peripheral area of the holding device. Such a fixing device can be designed in particular as a latching element or screw connection to the transverse adjustment drive module to be secured on a second side of the holding device. Advantageously, not only counteracting forces to a transverse pressing force of the ram through the lateral support section, but also transverse forces from the transverse adjustment drive module or its housing can be diverted into the holding device in a simple manner and at the same time safely, such as transverse forces when pulling a transverse ram out of the Area of the die opening can arise.

As a further development, screw connections can also be provided from above, a peripheral side and/or from below between the holding device and a transverse adjustment drive module attached thereto.

It is also an embodiment that such a transverse adjustment drive module has a transmission driving such a transverse plunger and a drive, in particular a motor, with the drive being arranged laterally to the transmission and the drive and the transmission being connected to one another via a toothed wheel and/or belt transmission are connected, the toothed wheel and/or belt transmission being pivotably mounted about a transmission axis of the transmission and/or about a drive axis of the drive.

In particular, this avoids a configuration in which a drive axle of the drive is guided in a linear direction in a mechanism - for example a crankshaft for transverse adjustment of the cross stamp - since instead of this, a parallel and spaced-apart course of a drive shaft and a gear shaft - for example the Crankshaft - can be set up. The drive--in particular an electric motor--and a gear driving the cross stamp can thus be arranged essentially within one plane and at the height of the body of the holding device. arises in the pressing direction thus a flatter structure, which enables a correspondingly low overall height of the entire press.

According to a preferred development, however, the pivotable mounting in the area of the belt transmission allows the drive to be pivoted to any particular side of the transmission, ultimately next to the holding device, so that only a small amount of space is sufficient in the radial direction. This also prevents collisions between the drive and surrounding components, e.g. an adapter or press frame, so that these can also be designed smaller.

Another configuration is that such a transverse adjustment drive module has a mechanism that adjusts such a transverse plunger - in particular a crank gear - in a first housing section and a gear that drives the mechanism in a second housing section, the first and second housing sections being pivotable relative to one another and the second housing section is fixed or coupled to the holding device.

The mechanism that adjusts the cross ram is, for example, a crank mechanism or eccentric, the drivable shaft of which leads into a further mechanism, which is arranged as a planetary mechanism, for example, between a motor and the crank mechanism. In particular, the second housing section with the gear is arranged on the outside next to the holding device and is also used for attachment to the holding device. Due to the possibility of pivoting the first housing section, the transverse adjustment direction of the transverse punch can thus be adjusted from, in particular, a direction directed axially to the die opening.

According to a further development, the first housing section can be pivoted about an axis parallel to the main pressing direction and also or at the same time can be pivoted about a gear axis of the gear. In such configurations, the transverse punch or its angle of attack on the body to be pressed is not only adjustable radially to the center of the die, but can also be pivoted in the direction of a tangential direction of the die.

Another configuration is that at least one gear mechanism of the transverse adjustment drive module is arranged radially on the outside next to the holding device in the transverse adjustment direction. To clarify, it is thus emphasized that according to a particularly preferred embodiment, at least some of the components of the transverse adjustment drive module that can be activated mechanically or by an electric motor are not arranged above or below the holding device in the pressing direction or parallel to the pressing direction, but preferably next to the holding device. This enables a compact design of the holding device, so that it can also be used in presses or adapters that are small in size transversely to the main pressing direction.

A further embodiment is that such a transverse adjustment drive module has a crank drive, in particular an eccentric drive. This enables a compact design with at the same time a large selection of modification options through the use of different eccentric disks in order to be able to set up different adjustment distances for the cross stamp.

However, other drive types and gear types can also be used, such as direct linear drives or transverse rams that can be adjusted via adjustable wedge surfaces.

A preferred transverse adjustment drive module has an electric motor drive as the drive, with an electric motor transverse linear drive, a mechanical or a hydraulic drive also being able to be used optionally, for example.

One embodiment of this is that a transverse adjustment plane of the transverse plunger is offset in its transverse adjustment direction, in particular offset parallel to an adjustment plane of the crank mechanism. In this way, elastic deformations in the main pressing direction are decoupled from the transverse pressing direction.

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

As an embodiment of this, it is preferred if the press is designed with a hydraulic, mechanical or electromotive main pressing force drive.

Another configuration is such a press with two such holding devices, each with an inside die receptacle and each with at least one outside transverse adjustment drive module receptacle with at least one transverse adjustment drive module, the second of the holding devices being arranged together with the components arranged on it above the first holding device and the die is formed separately in at least two parts along the main pressing axis in the die receptacles.

In particular, the second holding device and the components arranged thereon are arranged upside down compared to the first holding device and the components located thereon. In other words, an embodiment can also be realized in which both upper and lower components can be adjusted relative to one another of the press or the adapter, such a press arrangement is used, which has die components both above and below, which are moved to one another for pressing the shaped body or pressed part. In this way, for example, so-called chip breakers can be produced which have projections which extend laterally from a central body in different planes.

The formation of one-piece stamps, which can be coupled to the eccentric gear, is advantageous, since such stamps can be provided for a large number of stamp structures and the like. In addition, the stamps, which form a wearing part in such an arrangement, can be easily replaced. Such an arrangement preferably enables the eccentric drive to be supported on the holding device from the rear via a housing of the transverse adjustment drive module.

An embodiment is explained in more detail below with reference to the drawing. Show it:

a partially sectioned top view of such an arrangement.

How out 1 and 2 As can be seen, an exemplary ceramic and/or metal powder press arrangement 10 for pressing a molded part made of a ceramic and/or metal material 11 consists of a number of components which can be suitably put together as modular components.

For pressing, the material 11 is fed into a die opening 12 filled. In the die opening 12, the material 11 is pressed by means of one or more press dies 13 to form the molded part or pressed body with the desired structured design. The rams 13 can be adjusted with a main pressing force along a main pressing axis in a main pressing direction x.

The die opening 12 is formed in a one-part or multi-part die 14 . The die 14 is fastened or arranged as a particularly modular component on or in a holding device 15 . In particular, for receiving the die 14 , a die receptacle 16 is arranged or formed on the inside in and/or on a surface of the holding device 15 . The die receptacle 16 can optionally also be made up of a number of individual components which, spaced apart from one another, surround a central passage opening which is designed for the passage of the press ram or for the passage of components 47 carrying the press ram.

A transverse adjustment drive module receptacle 17 is formed on the outside of the holding device 15 and is designed for attaching and in particular temporarily fastening one or more transverse adjustment drive modules 18 .

A transverse plunger 19 is coupled, formed or fastened to the transverse adjustment drive module 18 . With the transverse adjustment drive module 18, the transverse punch 19 can be adjusted in such a way that a front section of the transverse punch 19 can be inserted into the die opening 12 in its longitudinal direction as a transverse adjustment direction y laterally or transversely to the main pressing direction x. For this purpose, the front section of the transverse punch 19 is passed through a suitable opening in the wall of the die 14 from the outside into the die opening 12 . je according to the configuration, the transverse punch 19 serves to carry out an external embossing after a final compaction of the pressed molded part, to compact the material 11 from the side during the main pressing process or to introduce it into the die opening 12 before the start of a main pressing process or before filling the material 11 to become. In addition to indentations running transversely or obliquely, through-openings can also be formed.

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

This intrinsically modular structure makes it possible to provide, for example, an outer die component 20 with a large number of possible passages, possibly also extending further in the circumferential direction, which can optionally also be designed to be rotatable about the main pressing axis. The inner matrix component 21, on the other hand, is specially adapted to the design of the molded part to be pressed. However, one-piece matrices can also be used.

In addition, a carriage track 22 is inserted in a section of the outer die component 20 on the upper side, over which a carriage 23 is guided, which serves to fill the die opening 12 with the material 11 .

The holding device 15 is supported on a press or adapter frame 24 or fastened to it on the underside. In the case of a matrix arrangement that can be adjusted within the frame, the holding device 15 is instead mounted on corresponding guide rods so that it can be adjusted along the main pressing direction x.

In the example in 1 In the embodiment shown, two transverse adjustment drive modules 18 are attached to the holding device 15 in opposite orientations. However, fewer or more such transverse adjustment drive modules 18 can also be arranged on the holding device 15, as for example in 2 is shown. A number of transverse adjustment drive modules 18 is ultimately limited by the scope of the holding device 15 and the length of time of the individual transverse adjustment drive modules 18.

In the case of the exemplary holding device 15 , the transverse adjustment drive module receptacle 17 is designed as a circumferential, annularly projecting projection as a first engagement configuration 26 . In particular, this projection can be angular in the manner of a rail or, as shown, can have an arcuate upper side. The projection is in particular formed directly on an upper side running transversely to the main pressing direction x on the lateral peripheral edge of the holding device 15 .

The transverse adjustment drive module 18 has a fastening section 25 which, in this configuration, has a hook-shaped projection pointing downwards as the second engagement configuration 27 . Viewed from below, the second engagement formation 27 forms a groove into which the projection of the first Engagement configuration 26 when placing the transverse adjustment drive module 18 engages. The hook-shaped projection protrudes from a housing wall of a housing 29 of the transverse adjustment drive module 18 in the radial direction.

Below the hook-shaped projection of the housing 29 , the housing 29 rests with its wall 39 in particular flat against a peripheral wall of the holding device 15 , the peripheral wall forming a support section 28 of the holding device 15 . An advantageous profile of a transverse force Fq is shown on the left-hand side of the illustration based on the transverse adjustment drive module 18, which is only sketched in part. A transverse force Fq acting in the outward direction via the transverse plunger 19 is deflected from above the holding device 15 in the outward direction and back 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 configuration 27 acts like a deflection point lying in between.

The housing 29 of the transverse adjustment drive module 18 is preferably formed from a first housing section 35 and a second housing section 36 arranged parallel to the main pressing direction x thereto. 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 plunger 19 and is designed, for example, as a crank drive, in particular as an eccentric drive.

The arrangement is shown as an example with a transverse adjustment plane of the transverse punch in the transverse adjustment direction, which is offset in or parallel to the main pressing direction to a gear adjustment direction y1 of the crank mechanism 37 is arranged.

The staggered arrangement can be implemented particularly easily by means of a punch receptacle 42 which is coupled to the crank mechanism 37 at the rear and which has a C-shaped mounting rail 43, the mounting rail 43 extending parallel to the main pressing direction x. The exemplary cross stamp 19 correspondingly has a rear projection 44 . The rear projection 44 of the transverse plunger 19 causes it to be fixed in the receiving rail 43 in the transverse adjustment direction y, but adjustable in the direction of the main pressing direction x.

From the mechanism 37, which is in particular a crank gear, a gear shaft 41 driving this leads into a gear 30. The gear shaft 41 leads along a gear axis 31, which in particular runs parallel to the main pressing axis. The gear 30 is designed to convert a rotational movement provided by a drive 33 directly or preferably via a belt gear 32 into a speed suitable for the crank gear 37 .

The drive 33 is arranged with its drive shaft 40 along a drive axis 34, preferably parallel to the transmission axis 31 and is spaced from the housing 29, for example in the radially outer direction. The drive 33 is arranged to be pivotable about the housing 29 by a preferably pivotable mounting of the belt transmission 32 in the attachment area on the housing 29 about the transmission axis 31 . As a result, the drive 33 can be arranged next to the housing 29 in a lateral position relative to the radial direction, so that less installation space is required for the transverse adjustment drive module 18 in the radial direction as viewed from the die opening 12 . 2 shows exemplary positions of the drives 33.

The transmission 30 is preferably arranged in the second housing section 36 on the underside. According to the preferred embodiment, the first housing section 35 on the upper side can be pivoted—in particular, pivoted about the transmission axis 31—to the second housing section 36 . As a result, in particular, pivoting of the first housing section 35 and thus also of the transverse stamp 19 can be adjusted. As a result, the transverse punch 19 can be adjusted not only radially in the direction of the center of the die opening 12 but also at an angle thereto.

Pivoting of the transverse stamp 19 out of the plane perpendicular to the main pressing direction x can be implemented, if desired, by correspondingly pivoting the housing 29 around, for example, the fastening section 25 and the transverse adjustment drive module mount 17 or its housing sections 35, 36 relative to one another.

Fastening elements 45, in particular screw bolts, can optionally be provided for connecting components such as the transmission 30 to the housing 29 or to its second housing section 36 and for fastening the housing 29 to the holding device 15.

On a side opposite the first engagement configuration 26, the holding device 15 has a further fastening element 46 in the form of a recess, for example. A projection of a fixing device 38 is inserted in the depression, with the fixing device 38 leading in a hook-like manner, starting from the projection in the outward direction and then running parallel to the main pressing direction x, to the housing 29 . If necessary at all, the fixing device 38 is used, among other things, advantageously as a support for receiving of the transverse force Fq directed away from the die 14.

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

Instead of a protruding projection, the transverse adjustment drive module receptacle 17 can also be formed, for example, by a circumferential annular groove into which corresponding hook-shaped or part-circular projections of the fastening section 25 of the transverse adjustment drive module 18 lead. Instead of a circumferential ring-shaped structure, several individual structures in the form of projections and/or depressions can also be provided as engagement configurations in the peripheral area of the holding device 15 .

Instead of arranging the engagement formation 26 directly on the edge of the holding device 15, a suitable engagement formation can also be formed on the holding device a distance from the peripheral edge in the direction of the die.
