Definitions
- the present invention relates to a system for manufacturing mouthpieces integrally in oriented tubes, with the possibility of regulating and distributing the thicknesses at will of the mouthpiece, allowing to strengthen the traditionally weaker areas, without increasing the process times of manufacturing and with optimal energy efficiency.
- the object of the invention is to form the openings with housing for sealing joints in a tube of molecularly oriented plastic material, integrated within the own production of the discontinuous systems.
- the invention is encompassed within the field of manufacturing processes of molecularly oriented profiles, in particular within discontinuous systems.
- Molecular orientation is a process by which, by applying a mechanical deformation to a previously extruded tube or proforma, under suitable conditions of temperature, pressure, deformation speed and deformation radius mainly, a substantial modification of its mechanical properties occurs, mainly the sigma of the material, the resistance to impact, improvement of creep, resistance to Ia crack propagation, Young's module improvement, etc.
- the discontinuous systems are based on producing the "element-to-element" molecular orientation, which is achieved through an expansion of the proforma within a mold that provides the definitive shape of the tubular profile.
- the oriented tubes must join with each other to form the conduction line and can do so in two ways: by means of sleeves, which are independent interconnection pieces that do it on pipes of constant and circular section, or by means of the formation of a mouth in each tube that allows one end to be introduced with one tube into another, each tube having its two distinct ends, one with a smooth shape and the other with a mouthpiece, and in this way the line is constituted, so that in this mouth there is sufficient space to accommodate a seal of flexible material, which ensures a tight seal of the network.
- Continuous or in-line processes by their nature, require that the embouching process be a separate process from that of the orientation, whereby special machines are required that, at a later stage than the orientation, perform the embouchure.
- the discontinuous processes allow the mouthpiece to be carried out in an integral manner, that is, to conform at the same moment in which the tube is formed, or be performed in a manner similar to that previously described, as an external process to the orientation of the own tube.
- Numerous patent documents can be cited for the realization of non-integral openings, as an extra process, being representative:
- the invention patent WO200200926 which develops a water-oriented tube heating system, limiting the heating zone with two plugs so that once heated and by pressure the tube is formed against a stamp that provides the shape. Subsequently, the proforma is cooled and the water is extracted.
- the system described in this invention patent allows a good temperature regularity, but it is very slow and suffers from a thickness control.
- the patent EP0930148 can be cited in which in heating a machine is established that heats the area to be formed of the tube, at a temperature similar to that of the orientation.
- the system consists in that, at one of the ends of the mold, a cavity is made where, when expanding the tube, a part of the tube on this section, giving rise to the mouthpiece, being subsequently cooled by contact of the metal of the tube on the mold.
- the upper part of the profile due to its upper diameter, is thinned after the elaboration of the mouth, as well as the profile in general, due to its larger diameter with respect to the constant section of the tube.
- This phenomenon common to all systems, is a real problem, since it is not only the weak point of the tube, but because the regulations require minimum thicknesses at any point of the tube.
- This thinning sometimes causes having to return the entire tube, with an extra expense of unproductive raw material, only to comply with said norm at the aforementioned point of the mouth.
- the present invention proposes a simple system that solves the above-mentioned problem, being based on means that, coupled to one of the closures of the mold or head allows the integral elaboration of the mouthpiece, contributing the important novelty of being able to make a distribution of thicknesses at will within the profile of the mouth, even getting that the traditionally thinner part of that profile, by the very nature of the process, becomes, if desired, the thickest and reinforced.
- the regulation of thicknesses is achieved within the integral embedding process, including the following means:
- a central support body which is intended to join the body of the pipe orientation mold.
- - Mechanical claws that fix the plastic pipe so that it does not move during the orientation or flare process.
- a sliding rod that pushes the proforma forward, so that this rod is initially delayed and when the orientation process begins, it moves axially in the opposite direction to the skate.
- Said rod is provided with an axial and central orifice that allows the passage, at inlet or outlet, of fluids both for the expansion process and for the cooling process, so that it is possible to project cooling fluid through said orifice of the rod , still having internal pressure.
- the system first comprises a support body (1) intended to be coupled on the head of the corresponding molecular orientation mold of pipes, and in which the conformation of the mouthpiece of the plastic tube that will be made It is introduced into such a mold.
- a coaxial and sliding skate (2) with a rear wall (3) as a stop means of the movement towards the inside of said skate (2) is mounted with axial displacement power on the body (1), skate (2) presenting its inner end in a conical shape (4) in correspondence with the inner face, while on the outer face it presents a step (5) as a stop of maximum displacement towards the outside of the support body
- the aforementioned sliding skate (2) incorporates heating elements (6) such as electrical resistors, although they may be determined by a circulation of hot fluid or any other appropriate means or system, the purpose of which is to heat the skate (2) to maintain this at the orientation and conformation temperature of the mouth.
- heating elements (6) such as electrical resistors, although they may be determined by a circulation of hot fluid or any other appropriate means or system, the purpose of which is to heat the skate (2) to maintain this at the orientation and conformation temperature of the mouth.
- small holes (7) are provided in the skate (2) to allow the entry of a lubricating fluid that will facilitate the sliding of the skate itself, all in such a way that the heating elements (6) and holes (7 ) referred to constitute a means of conditioning the remaining components of the system, for its optimal behavior, that is, a homogeneous distribution, reduction of forces, prevent wrinkles or scratches in the plastic and facilitate sliding.
- the system also includes a sliding rod (8) intended to push the proforma (11) or plastic tube forward, inside the mold, said rod (8) being affected by an axial and central hole (9) for the passage, inlet or outlet, of the intended fluids for the expansion of the proforma (11) and for cooling it.
- Said rod (8) incorporates at its inner end, means
- the skate (2) moves backwards slowly, allowing the plastic or preform (11) to adapt to the cavity that is left, which is done regularly and smoothly, since The skate (2) is heated to a temperature identical to that of the proforma (11), said sliding surface being able to be lubricated by the fluid that can be introduced through the holes (7) provided in the skate (2). Wrinkles do not occur because the internal pressure is always kept constant, pushing the plastic against the mold walls.
- the rod (8) begins to move in the opposite direction to the movement of the skate (2), pushing the proforma (11) and contributing that material to the global expansion.
- the speed ratio between the rod (8) and sliding skid (2) it is regulated where you want to place that contribution of material, preferably in the area of maximum diameter, but can always be regulated at will with the proper ratio of speeds and displacements.
- the speed of the rod (8) should be increased, that of the skate (2) reduced, or both, doing the opposite to thin the areas.
- the proforma (11) is cooled with a cooling fluid that is introduced through the hole (9) of the rod (8), while maintaining the internal pressure.
- the central hole (9) of the rod (8) is connected to the atmosphere so that depressurization occurs, and from there the extraction of the tube with its shaped mouth is carried out. It is only necessary to finish the opening by cutting the excess material, cleaning, placement of the seal and air conditioning.
