Definitions

  • the present application concerns a radial press for fitting flexible hose.
  • Patent EP 0 539 787 describes a radial press in which:
  • the radial press under examination is made up of a lower block 10 positioned on a platform 11 the top of which closes a frame 12, and a top block 13 placed above and facing the lower block 10 and which moves vertically in relation to the latter.
  • each On the facing sides of the two blocks 10, 13 each has a pair of surfaces 14, 15 sloping and at right angles to each other, separated by a horizontal surface 16.
  • the symmetrical axes of the surfaces 14, 15 and 16 intersect the horizontal axis A of the press.
  • four external bodies 17, rest on these surfaces 14-16, each one supporting a clamp 18 and the lateral surfaces 17' of these bodies are used to support and guide other internal bodies 19 also equipped with clamps 18.
  • the bodies 17 and 19 are arranged and configured so that the surfaces of the clamps facing towards the A axis are equidistant from it.
  • the movement of the top block 13 towards the lower one 10 causes the radial approach at the same speed of bodies 17 and 19 and consequently all the clamps 18.
  • the top block 13 is moved by an hydraulic drive system 20 positioned within the frame 12, below the platform 11, and is guided towards the lower block 10 by means of a pair of columns 21. These columns are anchored at the top to the top block 13 by bolts 22, they pass externally through the bottom block 10 and on opposite sides from the surfaces 14 and 15 and enter the frame 12 through the platform 11 to be fixed to the hydraulic drive system 20.
  • These drive systems 20 are made up of a drive unit 23 for closing the press under pressure around the item to be machined and a cylinder 24 for rapid approach/ retract of the top block 13 in regard to the lower block 10.
  • the drive unit 23 is made up of a single cylinder provided to house a drive piston 25 to which are keyed, in opposite positions in relation to the center, the two columns 21. In other words, these columns form the shafts of a single piston 25.
  • the guide columns 21 are, furthermore, fixed for example by screws to a reinforcing beam 26, positioned below the piston 25 and said beam being solid with the rapid approach/retract cylinder 24.
  • This cylinder 24 has a piston 27 connected to the lower block by means of its shaft 27' so that when oil under pressure enters the cylinder chamber 24, it causes a rapid movement of said cylinder and consequently the reinforcing beam 26, the guide columns 21 and the top block 13, in relation to the lower block 10 (see dotted line in the figure).
  • the drive piston 25 has a central reducer ring 28, which enables the piston thrust section to be noticeably reduced, therefore allowing the use of a low delivery pump.
  • the press is completed with a motor group 30 driving a pump 31 used to feed the hydraulic drive units. Thanks to the compactness of blocks 10,13 of the press and the drive units 20 themselves, the motor group 30 and pump 31 can be completely housed within the frame 12 of the press, protected and safe from unauthorized manoeuvres.

Claims (5)

  1. Radialpresse zur Verformung und Bearbeitung von Gegenständen mit kreisförmigen oder vieleckigen Flächen, wie z.B. flexible Schläuche, mit
    - einem unteren feststehenden Block (10), der auf einer Plattform (11) steht;
    - einem oberen Block (13), der oberhalb des unteren Blocks (10) angeordnet und diesem zugewandt ist und diesem gegenüber zum Öffnen bzw. Schließen der Presse vertikal beweglich ist;
    - einem hydraulischen Antriebssystem (20), das unterhalb der Plattform (11) des unteren Blocks (10) angeordnet und von einer durch eine Motoreinheit (30) angetriebene Pump (31) gespeist wird, wobei das hydraulische Antriebssystem (20) einen Zylinder (24) zum schnellen Zuführen bzw. Zurückziehen des oberen Blocks (13) zu/von dem unteren Block (10) sowie Antriebseinheiten (23) zum gegenseitigen Zusammendrücken der beiden Blöcke (10, 13) aufweist, wobei zwischen den beiden genannten Blöcken eine Anzahl von Flächen mit rechten Winkeln (14, 15) gebildet wird, die die Klemmen (18) der Presse tragen und führen, wobei die Klemmen so gesteuert sind, dass sie sich radial bewegen und dem vertikalen Hub des oberen Blocks (13) gegenüber dem unteren Block (10) folgen und wobei der obere Block in Richtung auf den unteren Block durch zwei Säulen geführt wird, wobei die genannten Säulen fest in dem oberen Ende des oberen Blocks (13) verankert sind, sich außen durch den unteren Block (10) erstrecken und von gegenüberliegenden Seiten aus - im Vergleich zu den rechtwinkligen Flächen (14, 15) - sich durch die Plattform (11) erstrecken, um an dem unteren Ende in den hydraulischen Antriebseinheiten (20) verankert zu werden, dadurch gekennzeichnet, dass die genannten Antriebseinheiten aus einem Zylinder (23) bestehen, der einen Antriebskolben (25) aufnimmt, an dem die Säulenführungen (21) befestigt sind, wobei die genannten Führungssäulen sich in Positionen befinden, die relativ zu dem Mittelpunkt des Kolbens (25) radial gegenüberliegend angeordnet sind insofern, als der Zylinder (24) zur schnellen Annährung bzw. zum schnellen Zurückziehen Bestandteil des Antriebskolbens (25) ist.
  2. Radialpresse nach Anspruch 1, dadurch gekennzeichnet, dass die genannten Säulen (21) unten an einem Verstärkungsbalken (26) befestigt sind, der in einer Linie mit dem genannten Antriebskolben (25) angeordnet und Bestandteil des Annäherungszylinders (24) ist.
  3. Radialpresse nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass der Antriebskolben (25) einen mittig angeordneten Reduzierungsring (28) aufweist, der den Schubteil des genannten Kolbens reduziert.
  4. Radialpresse nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass eine Platte (29) zwischen dem Antriebskolben (25) und der Trägerplattform (11) des unteren Blocks (10) eingesetzt ist, die dem genannten unteren Block während des Zusammendrückens entgegenwirkt.
  5. Radialpresse nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die hydraulischen Antriebseinheiten (20), die Pumpe (31) und der Motor (30) in einem Rahmen (12) angeordnet sind, der an seinem oberen Ende durch die Trägerplattform (11) des unteren Blocks (10) geschlossen ist.
