Definitions

the invention relates to a support ring by means of which it is possible to fix supply and evacuation pipes by butt welds to the heating radiators.
the invention also relates to a method and a matrix for the production of said support ring.
Support rings are known which are turned from a piece of metal and whose external diameter is preferably 23.7 mm, the internal diameter of 13 mm and the thickness of 11.4 mm. These rings are then generally provided with four radially oriented holes.
a support ring is produced which consists of at least two rings folded and pressed one inside the other with a metallic strip, by example of steel strip, and in which the radial openings are previously punched in the steel strip.
these rings When making these rings, no waste is formed and the production speed is considerably increased. In addition, these rings are to be manufactured at a cost price significantly lower than that of traditional rings.
the method used in this case according to the invention to obtain the new support ring consists in cutting a flat metal strip whose length is equal to the circumference of the outer ring, in cutting a second flat metal strip whose length is equal to the circumference of the inner ring, to fold the two ends of the two ribbons into an arc, to press transversely the first ribbon previously folded against and around a part of a core whose diameter is equal to inner diameter of the outer ring of the support ring, transversely pressing the second previously folded ribbon against and around a part of said core whose diameter is equal to the inner diameter of the inner ring of the support ring thus formed on the core, pressing the inner ring axially in the outer ring and pressing the two rings one on the other to measure.
the ends of the first ribbon are folded in an arc of a circle whose radius is equal to half the outside diameter of the outer ring and the ends of the second ribbon are folded in an arc of circle whose radius is equal to the half the outside diameter of the inside ring.
the support ring 1 consists of an inner ring 2 folded with a flat steel strip and a larger outer ring 3 also folded with a steel strip dish.
this steel strip are punched holes 4 which are oriented diametrically two by two when the rings are formed. After the formation of these rings 2-3, they are pressed one inside the other and one on the other, so that in a simple and inexpensive way one obtains a support ring which satisfies all the requirements formulated.
This matrix has a cylindrical core 5 with a cylindrical part 6 whose diameter corresponds to inner diameter of the inner ring 2 and a second cylindrical part 7 whose diameter corresponds to the inner diameter of the outer ring 3 to be formed.
Said core 5 is provided with two diametrically and longitudinally located grooves 8, in which a pressing element 9 is placed in a longitudinally sliding manner and whose external measurement is greater than the largest diameter of the core 5.
This pressure element 9 is fitted an axially sliding central punch 10.
This central punch has a flat surface 11 whose opposite lateral edges 12 are rounded with a radius which is equal to half the inside diameter of the outer ring 3 to be formed.
this punch also has a flat surface 14, which is narrower than the first surface 11 and whose opposite lateral edges 15 are rounded with a radius equal to half the inside diameter of the inner ring 2 With each flat surface 11-14 cooperates a step-down 16 to maintain on these surfaces the metallic ribbons AB whose rings 2-3 are formed.
a movable bending punch 17 Above the flat surface 11 of the central punch 10 is provided a movable bending punch 17, the machining surface of which has the same shape as said flat surface and which serve together for the preforming of the outer ring 3 to be formed .
This folding punch also has a semi-cylindrical groove 18 for pressing the metal strip A on the cylindrical part 7 of the core 5 and forming the outer ring 3.
a second punch to be folded 19 Opposite the other flat surface 14 of the central punch 10 is arranged a second punch to be folded 19, which are used together for preforming the inner ring 2 to be formed.
Said punch to be folded is provided with a semi-cylindrical groove 20 for pressing on the cylindrical part 6 of the core 5 the second metal strip B and forming the inner ring 2.
a calibrator punch 21 At the end of the core 5 is placed a calibrator punch 21 to press one on the other and to measure the rings 2-3 pressed one inside the other.
the operation of the matrix takes place as described below.
the punches to be folded 17-19 and the depressors 16 are moved away from the core 5 and the central punch 10 is slid between the punches to be folded.
a flat strip of steel strip A in which holes 4 have been previously punched and whose length is equal to the circumference of the outer ring 3 is slid between the central punch 10 and the bending punch 17.
a second strip of steel strip B is slipped , in which also holes 4 have been previously punched and whose length is equal to the circumference of the inner ring 2.
the lowerers 16 then press the strips AB firmly against the central punch 10 and the punches to be bent 17-19 are pushed towards the central punch 10.
the two ends of the two strips AB are curved in an arc of a circle.
the circular arcs of the ribbon A will thus have a radius equal to half the inside diameter of the outer ring 3 to be formed and the circular arcs of the ribbon B will have a radius equal to half the internal diameter 2.
the preformed ribbon B is pushed by the cylindrical groove 20 of the punch 19 to be folded around the cylindrical part 6 of the core 5, whereby around this perfectly completed inner ring 2 is formed.
the lowerers 16 are removed and the central punch 10 is moved relative to the core 5, whereby the outer ring 3 formed is pressed onto the inner ring 2 formed.
the pressing element 9 then presses the two rings 2-3 in the calibrator punch 21, in which the two rings are pressed firmly one on the other at the right measure.
a perfectly completed support ring 1 is thus obtained with four holes provided radially, the connection joints of the outer and inner rings 2-3 advance one over the other.
