Description

The invention relates to a powder press preparation method for preparing a powder press, in particular a metal and/or ceramic powder press, preferably a hard metal press, and a corresponding powder press system and a corresponding powder press.

Ceramic and/or metal powder presses—and also concretely hard metal powder presses—are known in principle in the prior art. During the production of pressed parts, these presses are usually integrated into a corresponding system, which also includes other components (e.g. one or more removal devices for pressed parts), a (powder) filling system, protective devices (e.g. housings) and/or a control cabinet.

Various pressed parts can also be pressed with conventional powder presses, which usually requires a tool change (for example including the exchange of a punch and/or a die). Among other things, the following activities are involved: First, the old tool must be removed. Furthermore, the powder material must (if necessary) be changed. In addition, the press usually needs to be cleaned. Usually a new tool has to be installed. If necessary, a new powder material must be connected. Often a zero and/or calibration must be done (but not always).

After such cleaning or preparation steps, the tool must then be adjusted (for example in relation to a desired height of the pressed part and/or a cutting edge of the same). In particular, the setting of a part height is often comparatively complex and difficult, in particular if the part is odd (e.g. conical in sections). The adjustment of cutting edges (of the stamping) often requires an assessment via a microscope, for which purpose, for example, two to five stampings must be test-pressed, for example iteratively, in order to (later) avoid tool breakage or the like. Occasionally, pressings also need to be sintered (requiring due allowance for adjustment). An accuracy of at least +/- 0.005 mm or +/- 0.002 mm is often required with regard to an adjustment of the press (in relation to the pressed part to be pressed). Problems that continue to arise during the actual pressing can be that the filling quantity (or the powder weight) is not provided precisely enough. This can result in production parts not exactly matching adjustment parts (which are pressed when the press is adjusted). Cracking problems and similar defects may also occur where appropriate.

The extremely demanding adjustment of the press (especially in the hard metal powder area) is usually carried out by highly specialized personnel.

Automation, in particular of the tool change (including the setting process), has not yet been implemented. This is possibly because even the slightest contamination or contamination (in the micrometer range) can be problematic. This requires extremely time-consuming cleaning, which is either not possible with automated solutions or, at best, appears to be extremely expensive. In particular, if the powder has to be changed, a corresponding automation is particularly complex.

Overall, it can be stated that it is very complex to adjust a pressing process permanently (in particular to a few micrometers).

Ultimately, hiring by specialist personnel can still be regarded as fundamentally advantageous.

In the prior art, however, the high expenditure of time for the steps explained above (in particular the preparation, cleaning and/or adjustment) of the respective press and the associated downtime of the corresponding system is regarded as a problem. It is therefore the object of the invention to propose a powder press preparation method for preparing a powder press, in particular a metal and/or ceramic powder press, preferably a hard metal powder press, with a downtime of a corresponding powder press or powder presses system should be reduced as much as possible. Furthermore, it is the object of the invention to propose a corresponding powder press system and a corresponding powder press.

This object is achieved in particular by the features of claim 1.

In particular, the object is achieved by a powder press preparation method for preparing a powder press, in particular a metal and/or ceramic powder press, preferably a hard metal powder press, comprising: preparing, preferably comprising cleaning and/or preparing and/or adjusting, at least one main body of the press in at least one preparation area, preferably in a cleaning and/or preparation area and/or in a setting area, and transferring at least a main body (press body) of the press (or the entire press) from the setup area to an operation area where pressing can be performed.

One idea of the invention is to prepare the powder press (at least partially) not in the actual operating area (in which the pressing then also takes place), but in one or more separate (or additionally provided) preparation area(s).

Preparation is to be understood in particular as a method step that does not directly relate to the pressing, but rather an action that is required for pressing the pressed part and takes place before this pressing. In particular, the preparation can include at least one cleaning step and/or adjustment step and/or a (other) preparation step, such as a tool change and/or powder material change.

Due to the local separation of an area for pressing and an area for preparing the powder press, downtimes (in relation to the system as a whole, which can include more than just the powder press, for example extraction devices and the like) can be reduced by Preparation of a powder press in a corresponding preparation area presses another powder press in the operating area pressed parts. This can increase productivity.

The main body of the press preferably comprises at least one press frame (for absorbing or dissipating the forces occurring during pressing) and/or a main drive for providing a pressing force. The main drive can be designed as an electric motor and/or hydraulically.

The press frame and/or prime mover are preferably configured to reside permanently (barring maintenance or repairs) in the same main body. Furthermore, the main body can also comprise at least one, preferably fixed, optionally exchangeable die and/or at least one, preferably exchangeable, punch.

In general, a die of the powder press is preferably designed as a fixed die. If a die and/or at least one punch is exchanged, this preferably means that the corresponding main body is modified or reconfigured. Components that are not to be exchanged (or exchanged) (at least in relation to regular operation, not necessarily in relation to repair and/or maintenance measures) can preferably be referred to as basic components of the main body.

For example, the main body of the powder compactor may comprise at least 50% by weight, preferably at least 80% by weight of the entire powder compactor. Alternatively or additionally, the main body comprises several or all of the parts of the press that are subjected to tensile stress during the actual pressing process.

According to the embodiment, the main body of the press can also be understood to mean the entire press, so that, for example, in the above step of preparing the entire press is then prepared in at least one preparation area and then transferred to the actual operating area.

The powder press can be designed as a module (which can be moved in its entirety) (as described in more detail below). Alternatively or additionally, this applies at least to the main body of the press.

Before the above step of making ready, the main body of the press (or the entire press) is preferably transferred from the operating area or another operating area to the at least one making ready area. A further operating area is to be understood in particular as an operating area that does not correspond to that operating area (the first operating area) to which the respective press is then transported in order to be able to carry out a pressing process there.

An operating range is to be understood in particular as a range in which a large number (of, for example, at least 50 or at least 100 or at least 500) pressed parts is pressed. An area in which pressing only takes place for test and/or adjustment purposes should not be understood as an operating area in this sense. A corresponding pressing of the plurality of compacts can then be carried out in a corresponding powder pressing method (disclosed herewith).

At least two preparation areas are particularly preferably provided, in particular at least one cleaning and/or preparation area and at least one adjustment area (provided in addition thereto). With corresponding configurations of the method, a corresponding preparation of the respective powder press can be carried out particularly advantageously. In particular, this makes it possible to simultaneously or over time overlapping with a setting of a respective powder press another powder press is cleaned (and possibly another powder press within the operating area carries out the actual pressing). Furthermore, it was recognized that in this way suitable personnel can be used particularly effectively for specific tasks. In particular, it is often the case that highly specialized and/or highly qualified personnel are required for the setting of the powder press, who can then effectively carry out their work in the setting area provided separately. For the cleaning and/or preparation steps explained above, trained personnel can be used who have the appropriate training (who do not necessarily have to have the high requirements for a precise adjustment of the powder press).

In further embodiments, at least three or at least four or at least eight different preparation areas (e.g. at least two or at least three cleaning and/or preparation areas and/or at least two or at least three or at least four corresponding adjustment areas can be provided.

At least the main body of the press can be cleaned during step a) (especially in the cleaning and/or preparation area). Alternatively or additionally, in step a) (in particular in the cleaning and/or preparation area), at least part of a tool, such as in particular a stamp, can be attached inside the main body, in particular by replacing at least one previous part of a tool, such as a previous one stamps. Alternatively or additionally, powder filling can take place in the cleaning and/or preparation step. The actions explained in this paragraph preferably do not take place in the settings area (but can alternatively or additionally be performed there).

The preparation preferably includes (in particular within the adjustment range) an adjustment of at least the main body of the powder press, in particular in such a way that the main body is immediately ready for operation at the end of the transfer step and, if necessary, after connection to any supply connections, with the adjustment preferably being a Setting a pressing program and/or setting in relation to a pressed part to be pressed, in particular with regard to a height and/or density and/or a weight and/or a cutting edge of the pressed part. In the above embodiments, the setting is made in particular in such a way that the tool (in particular the punch and/or die) no longer has to be changed in terms of a position and/or mode of operation in the actual operating area. The position and/or method of movement (relative movement) of parts of the tool are thus (in particular completely) defined in the setting area. In this context, it should be pointed out that adapter solutions are already known in principle, in which a certain presetting with regard to the position and/or the way in which the parts of the tool are moved can take place. However, a final adjustment (or final setting) can only take place after the arrangement (clamping) of such an adapter in the actual press (or a press frame), since this arrangement has a direct influence on a press characteristic. This can then preferably (in the actual operating range) be omitted in the method according to the invention. Unlike in the prior art, not only an adapter (without press frame and/or main drive) is exchanged, but in principle the entire press (or at least the main body of the same) as a corresponding module.

The preparation of the press, which is separate from the actual operating area, also enables other advantages. In particular, the press (or the main body) can be easily reached from all sides. This is not possible in the same way in a normal operating area due to safety devices (protective housings and/or protective covers). With such separate preparation, the press can (at least in principle, or in embodiments) be reached from all six sides (i.e. from the front, back, both sides, top and/or bottom). This is also advantageous for the actual setting, since the relevant specialist can now approach the press (or the main body) in such a way that he can make the appropriate settings as effectively as possible (without being prevented by corresponding protective structures or the like in the operating area). . The setting and/or arrangement and/or replacement of transverse pressing devices is also considerably simplified as a result. Here, too, possible free spaces in a separate preparation area (preparation site) have an advantageous effect.

Overall, the press (or at least the main body) can be set up independently of production and then, if necessary, coupled later (within the operating area).

For example, when changing tools, access can be made possible from at least three or at least four or possibly all six sides. This also allows the press to be designed in a different way (without the compulsory operations required for on-site adjustment Need to become). Overall, the press (or the main body of the same) can thus also be constructed in a comparatively simple manner and is therefore inexpensive. The press can be moved in a comparatively simple manner during set-up (adjustment) and, if necessary, the press (or the main body) can be viewed from all sides. A possible connection of powder can also be simplified.

• Ausbau eines in der Presse bzw. im Hauptkörper befindlichen Werkzeuges, Reinigen des Hauptkörpers (bzw. der Presse), insbesondere von Anschlägen. Einbau eines neuen Werkzeuges. Anschluss von Pulver (bzw. einer Pulverzufuhr). Durch eine derartige Reinigung bzw. Vorbereitung kann insbesondere eine saubere Maschine erreicht werden, sowie eine (wiederholbare) Werkzeugspannung. Kosten können eingespart werden.

The following steps can preferably be carried out in the cleaning and/or preparation area:

• Removal of a tool located in the press or in the main body, cleaning of the main body (or the press), in particular of stops. Installation of a new tool. Connection of powder (or a powder supply). Such cleaning or preparation makes it possible in particular to achieve a clean machine and (repeatable) tool clamping. Costs can be saved.

In specific embodiments, the press (or the main body) can be adjusted in the adjustment area with regard to the pressed part, in particular a height, density, a weight and/or a cutting edge thereof. An (optimal) adapted tool program can be set. A high part quality can be achieved. Resources are used comparatively effectively and distances can be saved if necessary.

The above-mentioned object is further achieved in particular by a powder pressing method, preferably metal and/or ceramic powder pressing method, more preferably hard metal pressing method, comprising the powder pressing preparation method of the above type and one related to it subsequent step of pressing at least one, preferably a large number of (for example at least 50 or at least 100 or at least 500) pressed parts (in particular identical pressed parts).

Hard metal is to be understood in particular as meaning a metal with an E module of at least 200 or at least 400 or at least 500 GPa and/or at most 1000 GPa. A density (in the pressed state) can be at least 5.0 or at least 8.0 or at least 12.5 g/cm ³ . A hardness can be at least 1000 or at least 2000 HV30.

Cutting and/or punching and/or drilling and/or milling tools are particularly preferably produced by the pressing method.

The above object is also achieved in particular by a powder press system, preferably metal and/or ceramic powder press system, more preferably hard metal press system, in particular for carrying out the above powder press preparation method and/or the above Powder pressing method, comprising: at least one powder press, preferably metal and/or ceramic powder press, more preferably hard metal press, and at least one operating area in which the pressing process can be carried out, and at least one provided in addition to the operating area Dressing area for dressing at least one main body of the press.

At least one powder press (possibly at least two or at least four powder presses) is preferably (during operation) arranged in the operating area. Furthermore, at least one transport device can be provided in the operating area, for example in order to transport a (respective) powder press to a specific location within the operating area. Furthermore, the operating area can have at least one, possibly at least two or at least four or at least six extraction device(s). The operating area can be defined by a corresponding production cell. If necessary, the operating area can be configured in such a way that no preparation steps (apart from moving the respective press to its specific storage location, where the pressed parts are then pressed accordingly) take place in it (possibly apart from possible connections, such as to a powder supply and /or hydraulic medium and/or compressed air and/or electricity and/or signal supply).

The corresponding operating area (or the corresponding production cell) can, for example, be protected from the outside by appropriate protection (enclosure). The (respective) preparation area can then be arranged outside of this protection (and either not protected or possibly protected with another protection). The settings area in particular can be secured with its own protection. Any preparation area can optionally be at least partially delimited with at least one wall and/or fence and/or the like (in particular also from another preparation area and/or a/the operating area), in particular over an angular range of (in total, if there are several separate structures present) at least 90° or at least 180° or at least 270° or at least essentially 360°, and/or opposite one, two, three or four sides.

In embodiments, a preferably automatic production cell is designed to form the operating area, which is designed to accommodate at least one press and/or at least one pressing part removal device and/or at least one conveying device for conveying at least one respective main body of the respective press (and/or includes such). Overall, unmanned operation can be enabled in the operating area (production area). A press change or press connection (of a specific press) or the corresponding main body can require less than 5 minutes and/or more than 1 minute (possibly including corresponding couplings to supply devices, for example to a filler).

The respective press (or corresponding main body) can preferably enter the production cell (operating area) in such a way that no post-adjustment needs are required. A high utilization of the (respective) production cell can be achieved.

A setting (in particular in the setting range) can be, for example, at least 5 or at least 10 and/or at most 40 or at most 30 minutes.

Cleaning and/or set-up (preparation) can take at least 5 or at least 25 and/or at most 40 or at most 30 minutes.

The above-mentioned object is also achieved by a powder press, preferably a metal and/or ceramic powder press, more preferably a hard metal press, in particular for carrying out the above powder press preparation method and/or the above powder press method and/or or as a component part of the above powder press system, wherein at least a main body of the powder press is designed as a module that can be removed from an operating area and transferred to a preparation area.

In embodiments, the press can be designed for a maximum pressing force of at least 10 kN, preferably at least 25 kN, more preferably at least 40 kN and/or at most 200 kN, preferably at most 120 kN, more preferably at most 80 kN.

The main body can comprise: at least one, in particular electromotive and/or hydraulic, main drive for providing a pressing force and/or at least one, possibly exchangeable, die and/or at least one, preferably exchangeable, punch and/or at least one press frame.

A corresponding module is to be understood in particular as a press module that is at least essentially ready for operation outside of the production environment or can be made ready for operation.

In embodiments, a docking system may be provided for docking within the production cell (operational area). The press can be accessible from at least four (particularly at least the four lateral) or (all) six sides. The powder can be coupled separately. A high level of powder purity can be achieved by (precisely) separating batches.

A maximum (or maximum possible due to the design) fill level can be, for example, at most 50 mm or at most 30 mm and/or at least 5 mm (or the powder press can be configured accordingly). A maximum (or maximum possible, due to the design) upper piston path can be at most 100 mm or at most 70 mm and/or at least 10 mm or at least 20 mm (or the powder press can be configured accordingly).

A height of the press is preferably at least 300 mm or at least 600 mm and/or at most 2000 mm or at most 800 mm.

A width of the press is preferably at least 100 mm or at least 300 mm and/or at most 700 mm or at most 500 mm. A length of the press is preferably at least 100 mm or at least 300 mm and/or at most 1200 mm or at most 700 mm or at most 500 mm.

The press can weigh at least 100 kg or at least 200 kg and/or at most 500 kg or at most 300 kg.

Overall, it is possible in a simple manner to keep the press (or the main body) comparatively clean.

Good repeatability can be achieved in tooling (with beneficial results, for example when stamping a cutting edge for a stamped part). Overall, costs can be saved during mold installation. Correspondingly qualified personnel can effectively carry out an adjustment of the respective press (in particular in the case of a multiplicity of corresponding presses within a plant).

With access from several (all) sides, a comparatively precise press may be required be built, since the usual space restrictions play less of a role (whereby the requirement to take up as little space as possible while still fulfilling a high level of rigidity is in a certain tension). This can also improve the quality of a pressed part.

Optionally, the powder press, preferably the main body, can comprise at least one cross pressing device.

Significant simplification can be achieved in particular with an optional transverse pressing (for example when connecting corresponding pins and/or slides for transverse pressing).

Production utilization can be significantly increased (to at least 80% or at least 90% or at least 95% or, at least almost, 100%) because the entire system does not have to stand still when a press is cleaned and/or converted and/or is discontinued.

A comparatively high powder purity can be achieved between the individual batches.

Overall, autonomous production can be achieved with significant cost reduction.

Optionally, all parts (including transverse pressed parts) can also be produced autonomously. A production can be planned precisely and is (at least essentially) independent of an operator.

The respective press (or the main body) is preferably configured in such a way that it can be lifted in its entirety from a first location and transported to a second location (without having to make any adjustments to the press at the second location or operating area according to the embodiment). .

During cleaning and/or preparing or Set-up (particularly in the cleaning and/or preparation area), the corresponding press (or the main body) can be configured in such a way that it is possible to move components of the press (with a corresponding set-up speed). However, pressing while providing pressing force is preferably not possible during cleaning and/or preparation.

During adjustment (particularly in the adjustment area), pressing with powder is preferably possible—at least for test or adjustment purposes. In particular, the corresponding pressing axes can be driven and (real) production speeds and/or (real) pressing forces can be made possible.

The production environment can preferably be operated unmanned or fully automatically. Several (different) types of powder can be used in the system (in particular the production environment).

In embodiments, instead of a (basically known) tool change, a press change or module change (or main body change) can take place.

A transverse pressing device can optionally (in a particularly simple manner) be integrated.

If necessary, further modules can be provided.

The above object is also achieved by a powder press production cell, comprising at least one powder press (10) according to one of the preceding claims, at least one transport device for transporting the at least one powder press, and at least one protective device (e.g. Housing and/or fence and/or grid and/or cage), in particular to prevent unhindered access to the powder press production cell, with the at least one powder press and the at least one transport device (at least partially) being arranged within the protective device .

Preferably, the powder press production cell is configured to automatically install the respective powder press or to arrange or turn it off for pressing and/or to connect it to a supply, for example with electricity and/or powder.

Further embodiments emerge from the dependent claims.

The invention is described below using exemplary embodiments which are explained in more detail using the figures. Here show:

• 1 a schematic representation of a plant for the production of powder pressed parts;
• 2 a schematic representation of a system according to the disclosure for the production of powder pressed parts; and
• 3 a powder press according to the disclosure.

In the following description, the same reference numbers are used for the same parts and parts that work the same way.

1 shows a plant for the production of powder pressed parts. The system includes a powder press 10 and a filling system 11. The press 10 and the filling system 11 are arranged within a protective device 12 (eg housing) surrounding them. The interior of the protective device 12 can be entered via an entrance 13, which is done in the prior art, for example, in order to adjust the press if other pressed parts (than the pressed parts pressed in a previous cycle) are to be produced. In the system according to the disclosure, the adjustment (and/or other preparation of the press) preferably does not take place within a protective device 12 or in the corresponding operating area of the press defined thereby.

Furthermore, the plant according to 1 also has a removal device 14 (e.g. comprising a robot or robot arm), which is configured to remove pressed parts produced by the press 10 from the press, so that they can be (temporarily) stored and/or transported further, for example.

Furthermore, the system (optional) has a control center 15 (switch cabinet).

In 2 a system according to the disclosure for the production of powder pressed parts is shown highly schematically.

In this embodiment (and at a specific point in time), several (specifically, but this is not mandatory, seven) powder presses 10 are arranged within an operating area 16 . Of the seven powder presses 10 shown, six are in a position to perform pressing operations (to produce compacts). A seventh (in 2 lower) press 10 is located on/in a transport device 17 and can, for example, be one of the six (in 2 replace upper) presses 10. The respectively replaced press (for example the leftmost press of the six upper presses) can then be removed from the operating area 16 if necessary. More presses 10 (in 2 , right) are located outside of the operating area 16 shown in dashed lines and in the present case are already fully configured so that they (as soon as they are positioned accordingly in the operating area) carry out pressing processes immediately (possibly after connection to supply structures, e.g. supply lines). be able. In particular, an adjustment to the pressed part to be pressed is no longer required (within the operating range 16). Specifically, there are three such presses 10 in the corresponding waiting position. Instead of entire presses, corresponding main bodies can also be prepared accordingly. Also, the lower press 10 located within the operating area 16 can be replaced with a corresponding main body. In other words, it is possible that the ultimately pressing powder presses 10 (i.e. those in 2 six upper presses within the operating area 16) can be formed by integrating or installing corresponding main bodies (press bodies).

The supply or exchange of corresponding presses (compacts) can be referred to as compacte flow. This is indicated by the arrow 18.

Furthermore, within the operating area 16 several (here for example six) removal devices (removal devices) 14 are provided. Precisely one removal device 14 is assigned to each (operational) press 10 here. However, it would also be conceivable that more or fewer removal devices (in relation to the presses 10) are provided. The arrows 19 illustrate a pressed parts flow, ie the removal and removal of pressed parts from the operating area 16. A (preferably central) powder feed device 20 is provided in order to supply the presses 10 within the operating area 16 with appropriate powder. A corresponding powder flow is illustrated by the arrow 21 . Alternatively or additionally, it is also possible to introduce the presses 10 into the operating area 16 in such a way that they are equipped with the appropriate powder.

Another press (or compact) 10 is on the far left in 2 shown. This press 10 has already been removed from the operating area 16 after a production cycle has been carried out and is now transported according to the arrows 22 to a cleaning and/or preparation area 23 . There the press is cleaned and/or prepared for a subsequent production cycle (e.g. provided with appropriate tools). The (respective) press (press body) 10 is then transferred according to the arrow 24 to an adjustment area 25, where an adjustment of the press takes place so that a specific pressed part (which differs in particular from the pressed part previously produced by the same press) can be produced . The press (or the press body) is preferably adjusted there in such a way that no further adjustments have to be made within the operating range 16 .

The operating area 16 is preferably configured as an unmanned area or in such a way that a partially or fully automatic arrangement of the respective press 10 and the production of pressed parts is possible.

3 shows a powder press 10 according to the disclosure (or a corresponding base body or press body). The press 10 comprises frame parts 27, at least one upper drive 28 (main drive) and/or at least one lower drive 29 (main drive) in order to provide a pressing force for an upper punch 30 or a lower punch 31. In concrete terms, the respective drive drives a corresponding stamp carrier 32 . Below the upper punch 30 there is a die 33 with a cavity 34 that can be filled with powder. The upper punch 30 and possibly the lower punch 31 can dip into this cavity in order to press a pressed part. Also provided is an optional cross press device 35 configured for cross press operations. (For example, to introduce undercuts and/or the like). The arrows 36 illustrate access options for the press.

In concrete terms, the press shown (or the press body/main body) is of modular design, so it can be used in particular as shown in 3 (Schematically) shown (at least with the components shown there) are transported as a whole in a set state.

The arrows 36 illustrate in particular that the present modular design makes it possible to move the press to a location where there are no obstructing structures (e.g. safety housings and/or removal devices), so that unhindered access from (all six ) pages is enabled.

At this point it should be pointed out that all parts described above, seen individually and in any combination, in particular the details shown in the drawings, are claimed as being according to the invention. Modifications of this are familiar to those skilled in the art.
