FR2725774A1 - Appts. for forming mouths on extremity of flexible parts of discharge pipes used for powder or liq. prods - Google Patents

Abstract

Appts. for forming mouths on the extremity of flexible parts of discharge pipes is novel in that it has a bowl-shaped cylinder (1) in which a piston (2) moves, the piston (2) being fed by an hydraulic pump with manual control, with an interposed compression spring (4) bringing the combined piston (2), axle (6), and semi-circular mould (7) taking the shape of the interior of the flexible part to the rest position. The moulds are interchangeable, one type of cylinder sufficing for 2 or 3 different dias. of flexible part. It is advisable to use the size corresponding to the dia. of the pipe.

Description

 The present invention relates to an apparatus for forming mouths on the ends of the hose, so that the fitting of the connected metal tube is then easy.

The @ dificulty is that the hose has an internal diameter
laughing, smaller than that of the tube, yes it 2 an outside diameter too large. The assembly is even sometimes impossible ~ ble manually without making ouelrues modifications ill-adapted dutube
the purpose of the device is to move the hose cylindrically, and to the required diameter, so that the e @ sleeve is relatively easy to maneuver, without damaging the hose or making the fitting ineffective.

It is obvious that the spacing of the hose must be greater than the diameter of the metal tube because when the pressure is released from the device, it ~ returns to a smaller diameter.

 The increase in the diameter of the hose must correspond to a gauge 17 forming part of the apparatus, for each different diameter of hose 18 corresponds to one gauge.

 The device according to the invention overcomes this drawback. It compotes a hydraulic, extra-flat short-stroke receiving cylinder, arranged so as to exert pressure perpendicular to the internal walls of the flexible.

 The cylinder is provided on one side with a half-moon cocoon serving as a base for the device and at the other end on the rod 6 of the piston is fixed another half-moon ball 7 of identical shape, aui moves to be pressed against the inner wall of the hose and cause a cylindrical expansion, which interests us particularly because other tools deforms by flaring it.

 this fitting is done by coating the walls with a fatty product to facilitate maneuvering.

 The cylinder is fed by a manual hydraulic pump 15, body type, by means of a connector 9 on which the pipe 16 of the pump is connected.

This cylinder is provided with tapped holes 10, 11, 12, for interchanging the shells according to the diameter of the hose,
it is done by removing the screws 13,14, and reattaching the
shells corresponding to the diameter of the hose.

The device according to a first characteristic is
intended for hoses with a diameter of fifty
and one, sixty three, seventy six millimeters;
for hoses with a larger diameter a cylinder
of larger diameter and greater travel is
necessary.

To form the mouth of diameter 51 flexible hoses
4 shells 19,20,21,22 are provided, of which 2 are dis
placed on the side walls of cylinder 1 maintained
by a ring 23. Lescocuilles 24, 25, provided for by the fle
xibles diameter 63.

With reference to these drawings, the device comprises a cylinder I in which a piston 2 moves with
seal 3 ensuring the seal, @u by the pressure of
oil coming from the pump, a compression spring 4
interposed between the top of the piston 2 and the placid bou
chon 5 brings the piston assembly 2 axis 6 shell 7 @@ half-moon 7 in the rest position.

The mouth of the hose is made in several
times from the end, and then every
about three centimeters when entering inside
of the hose until a sufficient length is obtained
health, which corresponds to the length of the tube
wants to fit in, which is around a dozen
of centimeters.

We recommend the use of a 17 caliber
that downstairs, when we put in oression 1'7pareil r) our
measure the expansion of the hose 18
The device has the following advantage;
10 a rapid execution of the fitting of the
flexible on the connecting tube.

 2 a rémlisatien @ of a maximum fitting without difficulty.

3. rapid completion of the mouth of the flexi
bie thanks to the very easy and fast handling of the device without any help whatsoever using a person or with associated tools
40 fitting carried out without flaring and without deforming the hose.

 50 well-adapted work and avoiding any risk of accident.

 The apparatus according to the invention is intended to make mouths on the discharge pipes of a wide variety of products, both food and industrial products, whether in the form of liquid, powder, mixed products
