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)
- Presse radiale pour la déformation et le façonnage d'articles présentant des surfaces externes circulaires ou polygonales, tels qu'un tuyau flexible, comprenant :- un bloc fixe inférieur (10) reposant sur une plateforme (11) ;- un bloc supérieur (13) placé au-dessus et en face du bloc inférieur (10) et déplaçable verticalement par rapport à ce dernier en vue de l'ouverture / la fermeture de la presse ;- des systèmes de commande hydraulique (20) placés en dessous de la plateforme de support (11) du bloc inférieur (10) et alimentés par une pompe (31) entraînée par un bloc moteur (30), lesdits systèmes de commande hydraulique (20) comprenant un vérin (24) pour une approche / un retrait rapide du bloc supérieur (13) par rapport au bloc (10), ainsi que des unités d'entraînement (23) pour la compression mutuelle desdits blocs (10, 13), lesdits blocs supérieur et inférieur formant entre eux un certain nombre de surfaces à angle droit (14, 15) utilisées pour supporter et guider les brides (18) de la presse, lesdites brides étant commandées de façon à se déplacer radialement en suivant la course verticale du bloc supérieur (13) par rapport au bloc inférieur (10) et le bloc supérieur étant guidé vers le bloc inférieur par une paire de colonnes (21), lesdites colonnes étant fermement fixées en haut au bloc supérieur (13), passant à l'extérieur à travers le bloc inférieur (10) et depuis les côtés opposés aux surfaces à angle droit (14, 15), et passant à travers la plateforme (11) pour être fixées en bas aux unités de commande hydraulique (20), caractérisée par le fait que lesdites unités de commande sont constituées d'un vérin (23) qui comprend un piston de commande (25) auquel sont fixées les colonnes de guidage (21), lesdites colonnes de guidage se trouvant dans des positions qui sont radialement opposées par rapport au centre du piston (25) dans lesquelles le vérin (24) pour une approche / un retrait rapide est formé d'un seul tenant avec le piston de commande (25).
- Presse radiale selon la revendication 1, caractérisée par le fait que lesdites colonnes (21) sont fixées en bas à une poutre de renfort (26) alignée avec ledit piston de commande (25) et formée d'un seul tenant avec le vérin d'approche (24).
- Presse radiale selon les revendications 1 ou 2 caractérisée par le fait que le piston de commande (25) présente un anneau réducteur (28) disposé de manière centrale afin de réduire la section de poussée dudit piston.
- Presse radiale selon l'une quelconque des revendications précédentes, dans laquelle une plaque (29) a été insérée entre le piston de commande (25) et la plateforme de support (11) du bloc inférieur (10), pour neutraliser le bloc inférieur pendant la phase de compression.
- Presse radiale selon l'une quelconque des revendications précédentes, dans laquelle les unités de commande hydraulique (20), la pompe (31) et le moteur (30) sont logés dans un bâti (12) fermé sur le dessus par la plateforme de support (11) du bloc inférieur (10).
