Claims
- 1. Device for straightening out a deformed element having undergone a deformation from an original shape, comprising:
- a pressure means for exerting pressure on the deformed element,
- a means for heating the deformed element, and
- at least one reinforcing support integral with said deformed element,
- wherein the means for exerting pressure on the deformed element is a balloon inflated by means of a fluid whose pressure is controlled,
- said device including two templates having the original shape of the deformed element, said two templates facing each other so that said deformed element is positioned between said two templates, one of said templates being placed inside the deformed element and the other of said templates being placed outside the deformed element, and said two templates being supported by supports and connected to flexible jacks acting on said templates so as to form a press.
- 2. Device according to claim 1, wherein the templates having the original shape of the deformed element are made of a thermoplastic material which is hot-cast, or are made of a hardening material which hardens roughly at room temperature, said hardening material having been cast in a part having the original shape of the deformed element.
- 3. Device according to claim 2, wherein the templates are reinforced with steel bars and edges of the templates are equipped with L-shaped members.
- 4. Device according to claim 1, which includes an ultrasound emitter means acting on the deformed element in order to make it vibrate.
- 5. Device according to claim 2, which includes an ultrasound emitter means acting on the deformed element in order to make it vibrate.
- 6. Device according to claim 3, which includes an ultrasound emitter means acting on the deformed element in order to make it vibrate.
- 7. Device according to claim 1, which includes a computer memory and a software collecting and processing data relating to at least one characteristic of the element to be straightened, including its original shape, as well as different data.
- 8. Device according to claim 2, which includes a computer memory and a software collecting and processing data relating to at least one characteristic of the element to be straightened, including its original shape, as well as different data.
- 9. Device according to claim 3, which includes a computer memory and a software collecting and processing data relating to at least one characteristic of the element to be straightened, including its original shape, as well as different data.
- 10. Device according to claim 4, which includes a computer memory and a software collecting and processing data relating to at least one characteristic of the element to be straightened, including its original shape, as well as different data.
- 11. Device according to claim 7, wherein the different data includes data selected from the group consisting of a shape of the templates, an inner pressure of the balloon or inner pressures of the baloons, and a temperature of the heating means.
- 12. Device according to claim 8, wherein the different data includes data selected from the group consisting of a shape of the templates, an inner pressure of the balloon or inner pressures of the balloons, and a temperature of the heating means.
- 13. Device according to claim 9, wherein the different data includes data selected from the group consisting of a shape of the templates, an inner pressure of the balloon or inner pressures of the balloons, and a temperature of the heating means.
- 14. Device according to claim 10, wherein the different data includes data selected from the group consisting of a shape of the templates, an inner pressure of the balloon or inner pressures of the balloons, and a temperature of the heating means.
- 15. Method for repairing deformed elements comprising the following steps:
- introducing at least one means for exerting pressure on a deformed element having a side having undergone a deformation from an original shape on a side opposite the side having undergone the deformation,
- placing a reinforcement so that the means for exerting pressure is situated between the deformed element and the reinforcement,
- introducing a template having the original shape of the deformed element between the deformed element and the means for exerting pressure,
- activating the pressure means,
- heating the deformed part by means of a heating means, and optionally striking the deformed part by means of ramming,
- finishing using a spot light in order to show remaining imperfections and correcting said imperfections,
- wherein the means for exerting pressure comprises at least one balloon filled with fluid under a controlled pressure and two templates having the original shape of the deformed element, said two templates facing each other so that the deformed part is positioned between said two templates, one of said templates being placed inside the deformed element and the other of said templates being placed outside the deformed element, and said two templates being supported by supports and connected to flexible jacks acting on said templates so as to form a press.
