Machine for forming and profiling a metal tubular product, like a pipe
A machine for forming, using a pressurized fluid, and for profiling, using profiling tools, a metal tubular product, for instance a pipe, in one and the same work cycle. In particular a machine for forming a tubular product in two different portions thereof by using one injector only and forming the tubular product in two different non-adjacent portions by using two injectors.
1. A machine for forming and profiling a metal tubular product using pressurized fluids and profiling tools comprising:
means for feeding a pressurized liquid to the machine,
a pusher configured and arranged for pushing the metal tubular product,
a vise,
a mold configured and arranged for determining a desired profile of the metal tubular product through a forming process, and
at least a first injector and a second injector provided with at least one battery of profiling tools, wherein the first injector includes a first aperture for providing pressurized liquid received from the means for feeding to an interior of the tubular product and the second injector includes a second aperture for providing pressurized liquid received from the means for feeding to the interior of the tubular product,
wherein the first injector is provided with two first radial channels and two first gaskets, wherein one of said first gaskets is seated within each of said first radial channels, and further wherein said first aperture is between said first radial channels, when considered along an axis of the first injector, and
wherein the second injector is provided with one second radial channel only and one second gasket only, where the second gasket is seated within the second radial channel, and
wherein the battery of profiling tools is placed next to at least one of the first and second injectors, and further wherein said at least one injector next to the battery is configured and arranged to move along an x axis or a z axis to thereby leave space for operation of the profiling tools when a forming step is completed according to a work cycle.
2. The machine for forming and profiling a metal tubular product, according to claim 1 , wherein the means for feeding is configured and arranged for feeding each of said first and second injectors with fluids at different pressures.
3. A machine for forming and profiling a metal tubular product using pressurized fluids and profiling tools comprising:
means for feeding a pressurized liquid to the machine,
a pusher configured and arranged for pushing the metal tubular product,
a vise,
a mold configured and arranged for determining a desired profile of the metal tubular product through a forming process, and
at least a first injector and a second injector provided with at least one battery of profiling tools, wherein the first injector includes a first aperture for providing pressurized liquid received from the means for feeding to an interior of the tubular product and the second injector includes a second aperture for providing pressurized liquid received from the means for feeding to the interior of the tubular product,
wherein the first injector is provided with two first radial channels and two first gaskets, wherein one of said first gaskets is seated within each of said first radial channels, and further wherein said first aperture is between said first radial channels, when considered along an axis of the first injector, and
wherein the second injector is provided with two second radial channels and two second gaskets, where one of the second gaskets is seated within each of the second radial channels, and
wherein the battery of profiling tools is placed next to at least one of the first and second injectors, and further wherein said at least one injector next to the battery is configured and arranged to move along an x axis or a z axis to thereby leave space for operation of the profiling tools when a forming step is completed according to a work cycle.
4. The machine for forming and profiling a metal tubular product, according to claim 3 , wherein the means for feeding is configured and arranged for feeding each of said first and second injectors with fluids at different pressures.
5. The machine for forming and profiling a metal tubular product according to claim 3 , wherein said second aperture is between said second radial channels, when considered along an axis of the second injector.
