Definitions

  • the invention refers to a steel canalization for modular bimetallic heating radiators, such a canalization can be carried out with no weldings and installed by screwing down the rectilinear pipe tracts, which constitute its horizontal pipes, into the laying ducts of a fixed part body of the modular elements where the couples of the mouths of the pipe tracts, which form the connection duct, are situated.
  • the above stated horizontal pipes are the residual working part of a preliminary structure integrated inside an aluminium covering during the radiator working process by high-pressure die-casting, subsequently tapered onto terminals by means of shearings which allow the heat to reach the above stated ducts.
  • bimetallic modular radiators which feature a canalization sector integrated into an aluminium structure have the advantage that both the size and the shape of the radiator can be adjusted to the users' specific needs with lower costs of production, control and assembling owing to their compositive simplicity, lower weight and minor overall dimensions.
  • the modular elements have a structure formed by an aluminium covering that can be manufactured through a high-pressure die-casting process, both their model and composition can be varied according to the house interior decoration and furnishing.
  • the monobloc-type steel pipes now in use consist of a counterposed pair of horizontal pipe tracts that can be jointed in different ways; therefore, they can be manufactured either by pressing down or welding the pipe tracts, or even they can be put together by jointing the successive pipe tracts coaxially.
  • the first system has the disadvantage of high operative costs caused by the welding process and by the risk of breakages; as regards the second system, though no welding operations are requested, the assembly procedure is rather complex as the pipe fittings must be rapported on pipe tracts which are located outside the main structure of the basic element.
  • the drawbacks of the second system are caused by the fact that for the heating the radiator modular parts must be installed with interposition devices such as reducing pipe joints on fixed stabilizers, or equipped with locators set on runners.
  • the invented system for realizing canalization improves the sector in particular way as: a) a very essential composition can be carried out during the radiator unit installation only by screwing down a pair of pipe tracts, which are part of the horizontal duct, into the ducts of the aluminium covering of the radiator element itself, where the mouths of the jointing pipe tracts are positioned in such a way to fit with the corresponding position of the pipe-fitting tracts owing to the original manufacturing system featured by the present invention; b) a cheaper, lighter heating element of smaller dimensions is featured as it can be manufactured with a minimum quantity of steel pipe tracts and through a pressure die-casting manufacturing process, which can be entirely carried out by an automatic cycle; c) the canalization assembling and installation can be made even by non-specialists, as they can be carried out by mnemonic comparison; d) a safety canalization is obtained as no weldings are necessary and also because the steel pipe tracts are connected on a thread line which ensures the
  • the manufacturing system features a modular element with an aluminium structure body 1 having on its ends couple of ducts 2 with screw threads 3 having centrally the mouths 4 of a couple of parallel steel pipes 5 symmetrically convergent at their ends; said couple of steel pipes integrated into the aluminium structure itself and forming fitting carrier pipe of the canalization.
  • the modular element with aluminium body 1 can be carried out starting from a preliminary steel structure 6 to be placed in a pressure die-casting mould to obtain the working bodies where the end parts 7 of the preliminary structure 6 come out centrally from the smooth wall ducts 2.
  • the above stated working bodies stop in a sequence one after the other in the shearing station 9, on a bearing 10, where a couple of oleodynamic cylinders 11 let simultaneously progress the shearing tools 12 into ducts 2 cutting the end parts 7 and discharge them through the openings 13.
  • a working body is thus formed having in the ducts 2 the mouths of the steel fitting carrier pipes.
  • the bodies thus obtained reach another working station where the screw thread 3 is operated in the ducts 2.
  • the canalization to be completed during the assembling of the heating elements by screwing down parts of steel horizontal pipe - with an external thread in relation with the screw thread 3 - into the sequence of couples of ducts 2.
  • Said parts consist of horizontal pipe-fitting tracts 14 with openings 15, to be sent to mouths 4 of the starting modular element of the series to be connected and so on until the last but one of them, and of pipe tracts for initial position 16 and for end position 17, the last tract with openings 18 to be conveyed onto the mouths 4 of the last modular body 1, both of them featuring a sealing crown 19 and an external holding part for the tool.
  • the heating units to be installed by placing two or more modular unit with an aluminium structural body 1, in a preliminary fixing condition, by previously interposing O ring 24 between their semiseats in a pendant position 22 and 23, then completing their assembling by screwing down one or more pipe-fitting tracts 14 - which form the horizontal duct- into ducts 2, until their openings 15 have come onto the mouths 4 of the steel pipes 5.
  • the installation is then completed by screwing down a pipe tract for initial position 16 into the duct initial part and, at the end, a pipe tract for end position 17 letting that the openings 18 come onto the mouths 4 of the last modular element.
  • Working realization of the present invention and assembly phase are illustrated by way of example in the drawings of sheets 1, 2 and 3. In sheet 1 fig.
  • FIG. 1 is front view of the duct tracts 20 which can be used to make the preliminary steel structure.
  • Fig. 2 is front view of the preliminary steel structure 6 with its parallel pipes held on terminals, which are centrally convergent and assembled with weldings 21 on their fixing borders.
  • Fig. 3 is side view of a working element, carried out by means of a pressure die-casting process, to show the end parts 7 emerging from ducts 2.
  • Fig. 4 is side view of a structural modular body 1, made of aluminium, obtained by shearing the pipe end parts 7 and by screw threading 3 the ducts 2.
  • Fig. 5 is longitudinal section view of an end part of the working body coming from the casting to show a duct 2 with the emerging end part 7.
  • FIG. 6 is longitudinal section view of the same structural modular body 1 with duct 2 screw threaded 3, to show one of the mouths 4 of the couple of steel pipe tracts 5.
  • sheet 2 fig. 7 shows the shearing of a radiator element to be worked according to the predetermined setting plan of a pair of ducts 2, such an element to be worked reaches the working line 8 by an intermitted feed, and places itself exactly near a bearing 10 standing behind.
  • a couple of oleodynamic cylinders 11, with shearing tools 12 in an initial position, as well as a couple of end parts 7 to be removed and emerging from the ducts 2 are here illustrated.
  • Fig. 8 is transversal section view of the same working process with a view of one of the shearing tools 12 in progress along a duct 2.
  • fig. 10 is partial view of the assembling of a radiator unit consisting of two modular bodies 1. It is to be noted a pipe-fitting junction tract 14 in its operative as well as the end pipe tract for initial position 16.
  • Fig. 11 is partial prospectic view of the end part of the modular body 1 with a cutaway of duct 2 with thread 3 and, axially, an exploded drawing of the junction pipe tracts 14 and the pipe tract for initial disposition 16.
  • Fig. 12 is a sectional transversal view of an end part of the modular element 1, showing the coinciding system between the openings 15 and the mouths 4.
  • Fig. 13 is a prospectic view of an heating unit composed of two modular elements with the pipe tract for end position 17.
