Definitions

  • the invention relates to a press device for a powder press for producing a compact from a compressible material, and to a corresponding tool changing system.
  • Powder presses for producing dimensionally stable compacts or molded parts from a compressible material conventionally comprise a frame, an upper and a lower punch arrangement and a die arrangement, which form a mold cavity into which the compressible or powdery or free-flowing material can be filled, and a drive unit, which is in operative connection with the punch arrangements and/or with the die arrangement, wherein the punch arrangements and the die arrangement can be moved relative to one another and pressed against one another by means of the drive unit along a pressing axis in order to form the compact.
  • Tools are available for the production of differently shaped and dimensioned compacts, whereby a separate, independently movable tool level is required for almost every component height.
  • tool planes are arranged one above the other in presses, with each of the tool planes comprising tool-specific structures, for example punch carriers, punches, support devices and guide systems.
  • a complemented tool plane is also referred to as an additional axis.
  • So-called adapter changing systems are also known.
  • So is in DE 31 42 126 describes a modular press, which consists of the actual press for applying the main pressing force and a press device that can be used in the manner of an adapter in the press.
  • the adapter-like press device comprises a framework with tie rods, which exist for guiding a large number of plates, punch carriers and in particular a die plate between connection devices which are also arranged or mounted in the framework and which establish a connection to the press rams of the press.
  • a base plate is provided, in which hydraulic devices are arranged for the relative movement of individual plates designed as stamp carriers.
  • the base plate is mounted in the actual press by means of a mounting lug.
  • the other plates are movably mounted in the framework relative to the base plate, with a die holding plate being rigidly connected via the framework to the lower connecting device of the adapter-like press device and being arranged in the framework so that it can be displaced relative to the upper connecting device.
  • Further plates or stamp carriers are movably mounted in the framework relative to the base plate, so that they can be moved between a filling position and a pressing end position.
  • the stamps are arranged on the respective stamp carriers, with the individual stamp carriers being supported on supporting devices or fixed stops in the final pressing position.
  • a tool change whether of individual tools or in the case of adapter-like tool changing systems, always requires careful adjustment of the individual punch carriers relative to one another and relative to the framework in order to avoid tilting or uneven pressing.
  • the disadvantage of an adapter changing system is that after the adapter has been inserted, the control and supply lines of the press required for the functions must be connected or coupled to the tools used and to associated adjusting drives.
  • EP 1 658 963 A2 discloses a press device for a powder press according to the preamble of claim 1, in which the tool planes are arranged one above the other, with adjusting drives of the individual tool planes being assigned to the press frame and being connectable to the tool planes by means of couplings in the installation position of the press insert.
  • stamp units of a powder press are known, with stamps, stamp holders and stamp carriers being able to be connected to one another.
  • Punch holders can be firmly connected to punch carriers via connecting pins, with the punch holders being accommodated in the pressing direction in receptacles correspondingly formed on the punch carriers and being locked by turning them around the pressing axis.
  • the object of the present application is therefore to improve a press device for a powder press for producing compacts from a compressible material in such a way that the installation of various tools is simplified and shortened, with investment costs being reduced. Furthermore, a tool change should be easier for the operating personnel to handle and less strenuous.
  • a powder press for producing compacts from a compressible material comprises a press frame, which has an upper and a lower frame section, an upper and/or lower punch arrangement, which each comprise a tool, and a die arrangement, which define a mold cavity into which the compressible material can be filled, and a drive unit which is in operative connection with the punch arrangement and/or the die arrangement.
  • the upper and/or lower punch arrangement and the die arrangement can be moved relative to one another and pressed against one another by means of the drive unit along a pressing axis.
  • a press device for a powder press known per se, which is arranged therein, has a plurality of tool planes arranged one above the other.
  • the tool planes are also referred to as additional axes and include, among other things, at least one stamp and the components that support it.
  • the term punch is a generic term and refers to both an upper and/or lower punch, which are required to produce a dimensionally stable compact. Accordingly, each additional axis comprises, for example, a plate, a stamp carrier or stamp holder, a stamp or cylinder, a support device for a fixed stop and/or a guide system.
  • the components are arranged on a plate-shaped level, which according to the invention is not formed in one piece, but rather in several parts.
  • the tool level accordingly comprises a support element which is fixedly arranged in the powder press and is not removed from it even when the tool is changed. Accordingly, connections and couplings to the supply lines of the powder press can remain in place and a complex adjustment of individual levels is not necessary.
  • an insertion element is provided, which can be received on the support element and held and mounted on it, the insertion element being able to be inserted in the horizontal direction via an insertion opening.
  • a receptacle is formed on the support element positioned in the powder press, which receptacle has an insertion opening on one side.
  • the insertion element designed to complement the receptacle can be inserted into the support element via the insertion opening.
  • the receptacle is U-shaped, ie each of the tool planes arranged in the powder press forms a U-shaped horizontal frame in which the correspondingly designed slide-in element can be accommodated.
  • the insertion openings of support elements arranged one above the other are oriented in the same direction and are easily accessible for the operating personnel.
  • a type of drawer principle is implemented, in which a carrying element remains in the powder press and an insertion element such as a drawer can be inserted via an opening.
  • the slide-in elements that can be inserted into the support elements of the tools include those components that complement a tool plane of one of the punch arrangements. These components can be built up or arranged on the slide-in elements outside of the press.
  • Complementary guide elements are provided along the slide-in path for better guidance on the support element and on the slide-in element, for example formed as overlapping grooves.
  • the slide-in element is pushed into a defined position in the support element along the slide-in path.
  • a locking device can be provided in order to lock inserted slide-in elements and support elements in the defined position.
  • a locking bolt is provided on an underside of the slide-in element, which, received in the defined position of the slide-in element, snaps into an opening provided on the support element on the support element of the tool plane. Accordingly, the position of the insertion element is fixed relative to the support element, in particular in the direction of the pressing axis.
  • locking devices are also provided.
  • a locking device is movably accommodated between the insertion element and the support element in a region of the insertion path.
  • This locking device can then be activated by an actuator, ie moved from a first position into a locking position, when the slide-in element is received in a defined position on the support element.
  • the locking device can preferably be activated by means of a pneumatic actuator, it being possible in particular for locking devices to be provided on both sides of the insertion path.
  • the slide-in element can also be locked in position in an additional axis by means of hydraulic clamping devices.
  • corresponding tool-specific components can be arranged on the insert element.
  • a punch can be arranged on a punch carrier on the insertion element, while a support device for a fixed stop and also, in particular, hydraulic actuators and included measuring systems are provided on the part of the tool plane remaining in the powder press, i.e. the support element.
  • support devices for fixed stops can also be provided on the insertion element and are thus removed from the powder press when the tool is changed.
  • the support element and the pushed-in element form an additional axis or a tool plane.
  • the high forces acting on the individual additional axes during a pressing process must be absorbed in such a way that there is no tilting or displacement of the tool planes, which are arranged largely horizontally in the powder press.
  • the respective tool plane has a shape that compensates for the differences in rigidity that occur due to the subdivision of the tool plane into the support element and the insertion element.
  • the multi-part, plate-like tool plane can be designed asymmetrically, so that a horizontal parallel displacement of the entire tool plane takes place under load during the pressing process and no tipping can be noted.
  • strength and deformation tests of the additional axes can be evaluated using a finite element method, which are the basis for determining the shape of a tool plane designed according to the invention, or the plate-shaped plane.
  • the invention provides that the tools required for a new product series can be prepared on the insert elements outside the powder press and easily transported to the location of the exchange.
  • This procedure is also known for a tool change with a prepared tool adapter, which is arranged as a press device in a powder press.
  • a modular system is provided which allows significantly simplified handling when changing tools. Accordingly, slide-in elements of the upper and/or lower tool can be removed as a respective slide-in set, for example by a forklift.
  • the press device and a tool carrier form a tool changing system in which the slide-in elements, including the required tool components, can be accommodated.
  • the slide-in elements can be equipped with the required arrangements of stamp carrier and stamp and arranged in the tool carrier. Individual slide-in elements can be fitted and then put together to form a set.
  • the tool carrier is designed in such a way that the slide-in elements that can be removed from or pushed into the tool planes can be accommodated in a holder and held in it by means of a clamping device.
  • the support can be provided by a traveling device, as will be described.
  • the tool carrier can be docked to the powder press, which is at a standstill, on a side from which the insertion openings of the carrying elements are openly accessible.
  • the tool carrier can, for example, be brought into a horizontal and/or vertical position by means of a lifting device, e.g. a lift truck or a crane device, in which the tool change can be carried out.
  • the tool carrier can also remain docked to the powder press, with the movable device removing or inserting the slide-in elements and being able to take them over for further treatment.
  • the movable device is integrated on the tool carrier in such a way that it can be moved in the direction of the insertion openings when the tool carrier is in the docked position.
  • the respective locking and locking devices are released, which fix the slide-in elements in the defined position in the tool plane or additional axis.
  • the insertion elements released in this way are transferred to the tool carrier and firmly connected to it by means of the clamping device.
  • spacers can be arranged between the planes of the insertion elements, which can be accommodated in position on the tool carrier.
  • the movable device of the tool carrier moves back into a starting position, so that the slide-in elements are withdrawn and removed from the support elements of the tool planes and from the slide-in openings.
  • the tool carrier and the removed slide-in elements accordingly form a unit which can subsequently be moved as a whole. It is possible to continue to treat the withdrawn slide-in elements as a set.
  • a set can be the upper tool, the lower tool or the entirety of the upper and lower tools, with individual tools from the set, in particular the upper tool, being able to be removed and fed to further treatment.
  • the tool carrier equipped in this way can be brought to a turning station.
  • the turning station is set up to transfer the slide-in elements arranged on the tool carrier to a transport unit.
  • the transport unit comprises clamping plates which are arranged parallel to one another and which open up a space between them.
  • the slide-in elements can be accommodated in the space; they preferably rest on horizontal supports, which are each arranged on the clamping plates so that they can be adjusted in height.
  • the equipped transport unit can be transported further to a set-up station.
  • the turning station is set up to turn the upper tool removed from the powder press or a transport unit equipped with slide-in elements by 180°. This proves to be advantageous for the tool change of the upper punch arrangement. By turning the upper tool by 180°, e.g. accommodated in the transport unit, it is possible for the operating personnel to set up the required components of a tool level or an additional axis easily and with good access from above.
  • the figure 1 shows a powder press 1 for producing dimensionally stable compacts from combustible material, in particular in powder or granular form, comprising a plurality of assemblies known per se.
  • the powder press 1, which is known per se, essentially has a press frame 2 with an upper and a lower frame section/traverse, which are held at a distance from one another by means of columns and are firmly connected and clamped to one another in such a way that the flow of force through them up to punch arrangements 3 or
  • the stamps also known as tools, can be built up.
  • the columns can be designed as sliding devices, along which a matrix arrangement 4 can slide and is therefore adjustable in height within a press unit.
  • a corresponding adjusting device can be provided for adjusting the matrix arrangement 4, which coordinates a height adjustment to the relative movement of the stamps.
  • a drive unit 5 is arranged on top of the press frame 2 to build up a pressing force.
  • the drive unit 5 is operatively connected to the upper punch arrangement 3 , ie the upper press tool, via an operative connection, so that this is moved in the direction of the die arrangement 4 or along a press axis 6 . Due to the applied pressing force, individual components of the pressing tools are moved relative to one another and clamped against the frame section on the underside, so that the stamps press the powder into a compact.
  • the press tool is assembled from components of a modular system, with simple adaptation to the pressed part to be pressed in each case being made possible.
  • a tool on the upper side of the upper punch arrangement 3 and a tool on the underside of a lower punch arrangement 3 can have a comparable structure.
