Abstract
The present invention discloses a system and a method for manufacturing fittings and connections for biaxially-oriented plastic tubes in an integral way from straight preformed tubes, with the possibility of adjusting and distributing the thicknesses as well as adjusting the specific stretching in the different areas of the fittings, allowing them to be reinforced or optimized during the method itself and without causing an increase in the production time or an increase in the raw material used, such that it allows for the manufacture of fittings of different geometric shapes (curves, tapers, couplers, branches, etc.)
Claims20
A system for manufacturing fittings and connections for biaxially-oriented plastic tubes from a straight preform tube of a non-oriented polymer tube which comprises a first end and a second end, wherein the system comprises:
- a heater configured to control the temperature of the preform tube;
- a first gripping head and a second gripping head, wherein the first gripping head is configured to grip the first end of the preform tube and the second gripping head is configured to grip the second end of the preform tube;
- a handling support configured to support the first gripping head and the second gripping head,
- a base plate that supports two mobile pieces configured to move about;
- a mold that comprises at least two parts, wherein each one of the parts of the mold is arranged on a mobile piece of the base plate, wherein the mold is configured to orient a deformed tube or the preform tube when the at least two parts of the mold are arranged in contact;
- a tempered climatic chamber configured to maintain the temperature of the preform tube at a first predetermined temperature;
- wherein the handling support together with the first and second gripping head are disposed in the tempered climatic chamber and are configured to at least rotate, stretch, contract or deform the preform tube.
